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

Hope this helps!

Step-by-step explanation:

Solving by factoring is a strategy used to solve quadratic in form polynomials, which are equations that can be written in the form of ax^2 + bx + c = 0. The goal of this strategy is to factor the equation into two binomials that are equal to zero. Once the equation is factored, we can use the zero product property to set each binomial equal to zero and solve for the roots or solutions of the equation.

The process of factoring begins by finding the greatest common factor of all the terms in the equation. Once the GCF is identified, it can be factored out of the equation. Next, we look for two binomials that multiply to give the remaining terms in the equation and add to give the remaining constant term.

For example, consider the equation: 3x^2 + 6x - 9 = 0.

To factor this equation, we first find the GCF of all the terms, which is 3. We can factor out 3 from all the terms, giving us: 3(x^2 + 2x - 3) = 0.

Now, we look for two binomials that multiply to give x^2 + 2x - 3 and add to give -2. We can see that (x-3)(x+1) satisfies this condition.

By factoring the equation, we have now factored the polynomial into (x-3)(x+1) = 0. We can use the zero product property to set each binomial equal to zero and solve for the roots: x-3 = 0 and x+1 = 0. The solutions are x=3 and x=-1.

By using the factoring strategy, we were able to solve the quadratic in form polynomial 3x^2 + 6x - 9 = 0 and find the roots x=3 and x=-1. This strategy can be applied to any quadratic in form polynomial and is a useful tool in solving equations.

Step-by-step explanation:

the denominator of a rational expression cannot be zero as this would make the expression undefined.

equating the denominator to zero and solving gives the value/s that x cannot be.

4x = 0 ⇒ x = 0

x = 0 ← is an excluded value in the domain

2

8x + 3 = 0

8x = - 3

x = - [tex]\frac{3}{8}[/tex]

x = - [tex]\frac{3}{8}[/tex] ← is an excluded value in the domain

3

2 - 10x = 0

- 10x = - 2

x = [tex]\frac{-2}{-10}[/tex] = [tex]\frac{1}{5}[/tex]

x = [tex]\frac{1}{5}[/tex] ← is an excluded value in the domain

4

x + 12 = 0

x = - 12

x = - 12 ← is an excluded value in the domain

(2x - 1)(x + 6) = 0

equate each factor to zero and solve for x

2x - 1 = 0

2x = 1

x = [tex]\frac{1}{2}[/tex]

x + 6 = 0

x = - 6

x = - 6 and x = [tex]\frac{1}{2}[/tex] ← are excluded values in the domain

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:

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

/6       /6

y = 18

If the exchange rate is 1 U.S. dollar to 81 Japanese yen, to purchase something that costs 50 dollars, you would have to spend 50 x 81 = 4050 Japanese yen.

Answer: You would have to spend 4050 yen to buy something that costs 50 dollars.

Step-by-step explanation: Since we already know the amount of yen that's equal to a dollar, all we have to do is multiply that number by the amount of dollars being spent.

This gives us: 81 * 50 = 4050. You would have to spend 4050 yen to buy something that costs 50 dollars.

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

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

The number of quarters Dalton has is 5.

Dalton has $3.05 in dimes and quarters. He has 13 more dimes than quarters. Therefore, the number of quarters he has can be calculated as follows:

Hence, using system of equation,

Therefore,

let

x = number of quarters

y = number of dimes

y = x + 13

0.25x + 0.1y = 3.05

using substitution method,

0.25x + 0.1(x + 13) = 3.05

0.25x + 0.1x + 1.3  = 3.05

0.35x = 3.05 - 1.3

I used a calculator lol

Answer: To calculate the % confidence interval for the proportion of US adults who spend less than three hours watching TV on an average day, we can use the following formula:

p +/- z*(sqrt(p(1-p)/n))

Where:

p = proportion of US adults who spend less than three hours watching TV on an average day (0.42)

z = standard normal score for a given level of confidence (e.g. for a 95% confidence level, z = 1.96)

n = sample size (1031)

Plugging in the given values, we get:

0.42 +/- 1.96*(sqrt(0.42*(1-0.42)/1031))

Simplifying, we get:

0.42 +/- 0.0156

So the 95% confidence interval for the proportion of US adults who spend less than three hours watching TV on an average day is approximately (0.40,0.44)

So what I did is (5+4) and times 10 = 90m.

P.s:If I'm wrong I'm sorry.

Step-by-step explanation:

well, it is a rectangle, where an isoceles right-angled triangle is cut off in the top left corner, but that triangle is added to the top right corner.

so, the area is the same as the regular rectangle.

we know, the area of a rectangle is

length × width

now, we know the length for sure (10 m).

what is the width ?

we know the part of the width until the triangle is 5 m.

and we know the leg length of the triangle is 4 m.

the width is simply the sum of the basic part and the leg length

5 + 4 = 9 m
