Answer:

39/110 or 0.355

Step-by-step explanation:

subtract

5/11 - 1/10 = 5x10/11x10 - 1x11/10x11 = 50/110 - 11/110

50/110 - 11/110 = 50-11/110 = 39/110

Answer:

Step-by-step explanation:

The percent decrease in Julia's monthly driving would be 35.9%. This is calculated by taking the difference between the two months (120 - 78 = 42) and dividing it by the initial amount (120) and then multiplying the result by 100. (42/120)*100 = 35.9%.

Her monthly driving decreased by 35%

Answer:

It is 12boys:13girls

Step-by-step explanation:

The total is 250 out of which 130 are girls. So it is 250-130 which is 120boys. Now to find the ratio it is 120:130 which in its simplest form is 12 boys:13 girls.

Answer:

The nine ounce box is the better deal.

Step-by-step explanation:

Kyle will save 2 cents/oz.

Answer: 9oz pack is better. C.

Step-by-step explanation:

9 ounces=$2.52

3 ounces=$0.84

1 ounce=$0.28

12 ounces=$3.60

3 ounces=$1.20

1 ounces=$0.30

0.30-0.28=0.02

3 ounces cost more for the 12oz pack than the 9oz pack.

Answer: This situation cannot be true for any positive value of x. The valid range would be 0 < x < 4. If the x is less than 4, the perimeter of triangle 1 is always greater than triangle 2.

Explanation: We need to add up the lengths of the sides for obtaining the perimeters first.

Triangle 1: 5x + 57

Triangle 2: 11x + 33

Then, we need to build up an inequality for the case which the perimeter of triangle 1 is always greater than triangle 2.

This means => 5x + 57 > 11x + 33

If we write "x" values on one side:

24 > 6x

Then dividing by 6 for both sides:

4 > x

This means that a positive value of x should be less than 4 for this particular situation.

Answer: 2x + 4x = (2 + 4)x = 6x

Step-by-step explanation:

The expression 2x + 4x represents the cost of buying the same number of cases of spring water and sparkling water. To express the total cost, we need to add the cost of buying the two types of water.

Since the expression 2x represents the cost of buying x cases of spring water, and 4x represents the cost of buying x cases of sparkling water, the total cost can be expressed as:

2x + 4x = (2 + 4)x = 6x

Therefore, the total cost of buying x cases of spring water and sparkling water can be expressed as 6x.

Alternatively, you can think of it as buying x cases of spring water at a cost of 2x dollars and x cases of sparkling water at a cost of 4x dollars. So the total cost is (2x+4x) dollars which is 6x dollars.

Step-by-step explanation:

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

to get the slope of any straight line, we simply need two points off of it, let's use those two in the picture below.

[tex](\stackrel{x_1}{6}~,~\stackrel{y_1}{194})\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{178}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{178}-\stackrel{y1}{194}}}{\underset{\textit{\large run}} {\underset{x_2}{8}-\underset{x_1}{6}}} \implies \cfrac{ \stackrel{Lbs}{-16 }}{ \underset{Weeks}{2} } \implies \cfrac{\stackrel{Lbs}{-8}}{\underset{Weeks}{1}}\implies {\Large \begin{array}{llll} -8~\frac{Lbs}{Week} \end{array}}[/tex]

Answer: to understand the relation between the basic math operators + , − , × , ÷ so that solving an equation becomes easier and time saving.

Step-by-step explanation: Inverse operations are used to reverse the effect of one operation on the other. The purpose of inverse operations is to understand the relation between the basic math operators + , − , × , ÷ so that solving an equation becomes easier and time saving.

Answer:

A) solution 2 is more acidic than solution 1

Step-by-step explanation:

A chemist prepares two acid solutions:

Solution 1: 3 parts sulfuric acid to 7 parts water

Ratio of sulphur to water: 3/7 (3:7)

Solution 2: 4 parts sulfuric acid to 9 parts water

Ratio of sulphur to water: 4/9 (4:9)

___________________________________________________

Part A: (using ratios to determine which solution is more acidic)

First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.

Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63

Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63

Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.

Mathematical Line (Not sure what you would call this lol): 28 > 27

Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)

Equation of solution 1: y = 3/7x

Equation of solution 2: y = 4/9x

Please find attachment for graph.

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

Answer:

[tex]s\geq 45[/tex]

Step-by-step explanation:

First, we need to find out how many spoons Lily actually needs.

420-159=420-160-1=269

Next, we need to find out how many packs of spoons Lily needs.

269/6=44.83333333…

Now we need to round this number down and add 1.

44+1=45

Finally, we need make an inequality. Remember, “at least” means greater than or equal to.

[tex]s\geq 45[/tex]

Answer:

To find out how much money is in the account after the growth, we can use the formula:

FV = PV(1+r)

Where FV is the future value of the account, PV is the present value of the account, and r is the rate of growth expressed as a decimal.

In this case,

PV = $225

r = 3.2% = 0.032 (as a decimal)

By substituting the values in the formula:

FV = PV(1+r)

FV = $225 * (1 + 0.032)

FV = $225 * 1.032

FV ≈ $232.7 (rounded to two decimal places)

Therefore, the account has $232.7 after the growth of 3.2%.

Answer: $232.20

Step-by-step explanation:

3.2%=0.032

225x0.032=7.2

225+7.2=232.2

Answer:

5/6

Step-by-step explanation:

In fractions, you can convert 1/2 and 1/3's denominators into a common number.
First, multiply 2 by 3 and 3 by 2. The denominator will be 6
Then, multiply the top by the same number (the numerator)
1/2*3/3 = 3/6.
1/3*2/2=2/6
3/6+2/6=5/6

Answer: 1.5, 1 1/2

Step-by-step explanation:

1/2 / 1/3
reciprocal of 1/3 is 3/1
1/2 x 3/1 = 3/2 = 1 1/2
