How do you subtract fl oz from liters?
Answers
Answer:
Step-by-step explanation:
Convert a liter or liters what how ever many the question says to fl oz. 1 liter= 33.814, so if you need to minus 2 cups then just minus 16 fl oz, from 33.814, or the given amount in the question.
Answer:
Step-by-step explanation:
1. convert fl oz to liters using a conversion factor
2. 1 liter = 33.814 fl oz approx
3. you must divide the # of fl oz by 33.814
4. For example, if you wanted to subtract 20 fl oz from 3 liters, you would first convert the 20 fl oz to liters: 20 fl oz/33.814 = 2.406
5. Then you would subtract the converted fl oz from the liters: 3 liters-0.594 liters= 2.406 liters
20 fl oz = 0.594 liters, and 3 liters minus 0.594 liters equals 2.406 liters

ayo earns 50,000 monthly and he spends 35,000 altogether. if he saves the rest, find the percentage of his savings
Answers
Answer:
30%.
Step-by-step explanation:
Ayo earns 50,000 monthly and he spends 35,000 altogether, so he saves the rest of his income. To find the percentage of his savings, we can divide his savings by his total income and multiply by 100.
His total income is 50,000
His total expenditure is 35,000
His savings = total income - total expenditure = 50,000-35,000 = 15,000
So the percentage of his savings = (savings / total income) x 100 = (15,000 / 50,000) x 100 = 0.3 x 100 = 30%
Therefore, Ayo's savings percentage is 30%.
Consider parallelogram JKLM below.
Use the information given in the figure to find x, mZM, and mZMJ

K
Answers
Part 1:
Notice the lengths of the top and bottom sides. These sides are lengths of 3x and 3. Since JKLM is a Parallelogram, it is a property that opposite sides are parallel and congruent. Because the top and bottom sides are opposite each other, they are parallel and congruent. This means that the side lengths are equal. We can form an equation to solve for x:
3x=3
Solve for x:
Divide both sides by 3:
3x/3=3/3
x=1
This should make sense because 3(1)=3, meaning this pair of sides are equal.
So, x=1 is the answer for this part.
Part 2:
Now, let’s find the m∠M. To find the measure of angle M, we must apply another Parallelogram property: opposite angles are congruent.
Therefore, the opposite angle of angle M is angle K. Angle K measures 70,° which means angle M must also measure 70° by the properties of a parallelogram.
So, the answer is: m∠M=70°
Part 3:
To find m∠MJL, we will apply another Parallelogram property: adjacent (angles on the same side) sum to 180.° This is the reason we found the measure of angle M, since it will help us solve for angle MLJ.
Therefore, m∠MJK + m∠JML = 180.°
Now, we must break angle MJK down into its adjacent angles that sum to it, which includes angle MJL. So, m∠MJK = m∠MJL + m∠KJL. We know that m∠KJL = 51.° Now, let’s substitute this information into the equation:
m∠MJL+51°+70°=180°
Let’s solve for angle MJL:
Combine like terms:
m∠MJL+121=180
Subtract 121 from both sides:
m∠MJL=180-121
m∠MJL=59°
This should make sense because 59+51+70=180.
So, the answer is: m∠59°

If BD=7x-10, BC=4x-29, and CD=5x-9, find each value
Answers
Answer: We know that in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Using the triangle inequality theorem, we can set up the following inequality:
BD + BC > CD
7x - 10 + 4x - 29 > 5x - 9
Simplifying, we get:
11x - 39 > 5x - 9
Subtracting 5x from both sides, we get:
6x - 39 > -9
Adding 39 to both sides, we get:
6x > 30
Dividing by 6 from both sides, we get:
x > 5
So x must be greater than 5.
To find the value of BD, we can substitute the value of x in the equation:
BD = 7x - 10
BD = 7(5) - 10 = 25 - 10 = 15
To find the value of BC, we can substitute the value of x in the equation:
BC = 4x - 29
BC = 4(5) - 29 = 20 - 29 = -9
To find the value of CD, we can substitute the value of x in the equation:
CD = 5x - 9
CD = 5(5) - 9 = 25 - 9 = 16
So, BD = 15, BC = -9, CD = 16

Answers
Step-by-step explanation:
16 transactions per hour (60 minutes).
in short :
16/1
or 16/60 (for minutes instead of 1 hour)
in 20 minutes 6 transactions.
so,
6/20
hour many transactions then in 1 hour (60 minutes) ?
60 = 20×3
so, to bring the ratio to 1 hour (60 minutes) we need to multiply the denominator by 3. and to keep the ratio value, we need to to do the same thing also to the numerator.
therefore,
6/20 × 3/3 = 18/60
so, the clerk will do 18 transactions per hour.
he will meet his goal of 16 : true
he will even exceed but definitely meet his goal.
12 transactions in 1 hour : false
9 transactions every half hour : true
as he will do 18 transactions in 1 hour, he will do half of these transactions (9) in half an hour.
96 transactions in 6 hours : false
18/1
6 = 1×6
so, with the same trick as above we get
18/1 × 6/6 = 108/6
and we see, he would complete 108 transactions in a 6- hour shift.
96 would be right, if the actual ratio would be 16/1 :
16/1 × 6/6 = 96/6

What is the value of y that makes T Parallel to U
Answers
Answer: y = 18
Sentence: The value of y that makes T Parallel to U is 18.
Step-by-step explanation:
We are given 3 expressions:
(7x)(6y + 9)(3x + 36)We know that since the angle (7x) is on the same line as the angle (3x + 36), we can therefore determine that they correspond to each other. I referred an image to help demonstrate this concept. So since they correspond to each other, that means they have the same value (meaning they are equal to each other).
We can set both expressions equal to each other.
7x = 3x + 36
And solve:
7x = 3x + 36
-3x -3x
4x = 36
/4 /4
x = 9
now we know the value of x, we can plug it into one of the equations. We can plug it in to 3x + 36 to help with the process in solving y.
3(9) + 36 = 63 degrees
Since 6y + 9 and 3x + 36 (63 degrees) are supplementary angles, we can subtract 180 from 63.
180 - 63 = 117
now we know that 117 degrees = 6y + 9 BUT!, we need to solve for y, because that's what the question is asking for.
So lets solve for y:
117 = 6y + 9
-9 -9
108 = 6y

y = 18

The difference between two numbers is 9. Four times the larger number plus one-half the smaller is 45. What are the numbers?
Answers
Answer:
To solve this problem, we will use the following steps:
Step 1: Let's assume that the larger number is x and the smaller number is y, we know that the difference between the two numbers is 9, so we can write the equation: x-y = 9
Step 2: We know that Four times the larger number plus one-half the smaller is 45, so we can write the equation: 4x + 0.5y = 45
Step 3: Now we have two equations with two unknowns, we can solve for one of the unknowns by isolating it in one of the equations.
x-y = 9
x = y+9
Step 4: Now we can substitute the value of x in the second equation
4(y+9) + 0.5y = 45
4y + 36 + 0.5y = 45
4.5y + 36 = 45
4.5y = 9
y=2
Step 5: We can substitute the value of y in one of the equation, to find the value of x
x-2 = 9
x = 11

Triangle abc undergoes a sequence of transformations 1 reflection across line x=1. 2 dilation by a factor of 2 centered at the origin. What is the resulting image
Answers
The resulting image of the triangle ABC after the transformations is given by the image presented at the end of the answer.
How to obtain the image of the triangle?The vertices of the original triangle ABC are given as follows:
A(0,2), B(3,2), C (2,7).
First we have the reflection across the line x = 1, which is a vertical line, meaning that:
The x-coordinate remains the same distance from x = 1, however on an opposite direction.The y-coordinate remains constant.Hence the vertices after the reflection are given as follows:
A'(2,2), B'(-1,2), C'(0,7).
For example, a coordinate of 0 is one unit left of x = 1, hence the coordinate of the image will be one unit right, at x = 2.
The dilation with a scale factor of 2 centered at the origin means that the coordinates are multiplied by 2, hence:
A''(4,4), B''(-2,4), C''(0,14).

Two consecutive integers are such that 3 times the larger exceeds twice the smaller by 24. find the integers.
Answers
Answer:
26 and 27
Step-by-step explanation:
If the smaller integer is represented using the variable n, then the next consecutive integer is n + 1
3 times the smaller => 3n
2 times the larger => 2(n + 1 = 2n + 2
We are given 3 times the larger exceeds twice the smaller by 24 which can be represented as:
3n - (2n + 2) = 24
3n - 2n - 2 = 24
n - 2 = 24
n = 24 + 2 = 26

Step-by-step explanation:
First, what is 7.86 by 4.564?
It is 35.87304.
But the answer needs to be in significant figures, so how do we do that?
Well, significant figures are the numbers that comes after the decimal place. For example, 0.52, which has 2 significant figures.
So with 7.86, there are 2 significant figures and with 4.565, there are 3.
We want to use the one with the least amount of significant figures, so we would round our answer to the hundredth:
35.87
Hope this helps!
The required answer is 35.8730
The number of significant figures in a measurement represents the level of precision in that measurement. In general, the last digit in a number is considered uncertain and is rounded based on the number of significant figures.
When performing arithmetic calculations, the result should be rounded to the same number of significant figures as the least precise measurement used in the calculation.
In this case, the least precise measurement is 4.564, with four significant figures. Therefore, the final result of the calculation 7.86 x 4.564 should be reported with four significant figures.
The answer is 35.87304 and should be reported as 35.8730

Answers
Converting within measurement systems means that we are changing the unit of measurement from one to another.
What is Converting within measurement systems?It is referred to as converting units within measuring systems if we do it using the metric or conventional systems. The conventional system and the metric system are the two most widely used measurement systems. In other words, we are not converting units from customary to metric or vice versa.
Simple unit conversions can be performed mentally or with one-step multiplication or division. There are, however, more difficult conversions that call for many conversions between a wide range of units.
The Unit Factor Method, another name for the Dimensional Analysis process, is a mathematical technique that takes advantage of the fact that any number or statement may be multiplied by "one" without changing its value. By multiplying the previous measurement by one (or more) different representations of the number 1, you can convert units. Although the measurement's value is unaffected by the factor of 1, the measurement's units are.
A ratio of one is referred to as a conversion ratio or unit factor. The names of the units that will be used in the conversion are listed in this ratio. It can be used to convert values both within the English and Metric Systems and between the two. The idea of equivalent values serves as the foundation for the conversion ratio.

A bank has launched a three-year structured deposit that offers an effective annual interest of 8% for the first 18 months, quarterly interest of 1.5% for the next 6 months and semi-annual interest of 2% for the last 12 months. If I wish to receive $100, 000 on the maturity date (that is, on the last day of the third year), how much, to the nearest dollar, should I invest? (Assume that interest rates and principal are guaranteed)
Answers
Answer:
To determine how much you should invest to receive $100,000 on the maturity date, you will need to calculate the present value of the cash flows at the beginning of the investment. The present value is the amount of money you would need to invest today to receive a certain amount at a future date, taking into account the time value of money and the interest rate.
You can calculate the present value by using the formula:
PV = CF / (1 + r)^t
Where:
PV = present value
CF = cash flow (the amount you will receive at the maturity date)
r = interest rate
t = time (in years)
The first 18 months, the interest rate is 8% per year, which is equivalent to 8/12 = 0.67% per month.
The next 6 months, the interest rate is 1.5% per quarter, which is equivalent to 1.5/4 = 0.375% per month.
The last 12 months, the interest rate is 2% per semi-annual, which is equivalent to 2/2 = 1% per month.
For the first 18 months, the present value of the cash flow is:
PV = 100,000 / (1 + 0.0067)^(18/12) = 95,167
For the next 6 months, the present value of the cash flow is:
PV = 95,167 / (1 + 0.00375)^(6/12) = 94,853
For the last 12 months, the present value of the cash flow is:
PV = 94,853 / (1 + 0.01)^(12/12) = 94,853
So, to receive $100,000 on the maturity date, you should invest 94,853 dollars to the nearest dollar.
