Which of the following girls will have the greatest percent of change in height if they each grow 3 inches over the summer?Girl Current Height
Ann 60 inches
Betty 62 inches
Carol 64 inches
Diana 66 inches

Answers

Answer 1
Answer: If you would like to know which of the girls will have the greatest percent of change in height, you can calculate this using the following steps:

x% of 60 inches is 63 inches
x% * 60 = 63
x/100 * 60 = 63
x = 63 * 100 / 60 = 105% ... 5%

y% * 62 = 65
y/100 * 62 = 65
y = 65 * 100 / 62 = 104.84% ... 4.84%

w% * 64 = 67
w/100 * 64 = 67
w = 67 * 100 / 64 = 104.69% ... 4.69%

z% * 66 = 69
z/100 * 66 = 69
z = 69 * 100 / 66 = 104.55% ... 4.55%

The correct result would be Ann (60 inches).

Which statement is true about a line and a point? A point and a line have length as a dimension to measure. A point is a location and a line has many points located on it. A line and a point cannot lie on the same plane. A line and a point cannot be collinear. 2. Trisha drew a pair of line segments starting from a vertex. Which of these statements best compares the pair of line segments with the vertex? The line segments and the vertex have length as a dimension of measurement and there are three collinear points on each. Line segments and the vertex have two endpoints each and the distance between the end points is their dimension. Line segments have two endpoints and a vertex is a common endpoint where two line segments meet. The line segments and the vertex have their lines extending in one direction only and the lengths of both are infinite.

You are decorating your bedroom. To get the paint colour you want, you mix 2 parts red with 3 parts cream and 1 part blue.How much cream and blue paint will you need to mix with 4 litres of red?

Answers

Answer:

6 liters of cream.

2 liters of blue.

Step-by-step explanation:

We are given that  To get the paint colour you want, you mix 2 parts red with 3 parts cream and 1 part blue.

Ratio is  2:3:1

Now we are given that we need to calculate how  much cream and blue paint will you need to mix with 4 litres of red

Since we are mixing 2 parts of red and we have 4 litres

⇒2 times 2 = 4 litres

So, since they mix 3 parts of cream

Thus 3*2= 6 lites

So they use 6 liters of cream.

Since they mix 1 parts of blue

Thus 1*2= 2 liters

So, they use 2 liters of blue.
The cream paint is 3/2 of the red, since there are three parts cream for every two parts red.  Similarly, the blue paint is 1/2 of the red.  Thus, there are 3/2*4=6 liters cream paint and 1/2*4=2 liters blue paint.

The circle graph shows how a family spends its annual income. If $33,750
is used for Clothing and Savings combined, what is the total annual income?

Savings
9%
Insurance
10%
Entertainment
11%
Auto
14%
Clothing
16%
Food
18%
Housing
22%

Answers

we find that the total annual income is $40,178.57.

To find the total annual income, we need to subtract the amount spent on clothing and savings from 100%.

Clothing and savings make up 16% of the income, so the remaining 84% is used for other expenses.

Let's call the total annual income 'x'.

The equation can be written as:

84% of x = $33,750.

To solve for x, we can set up a proportion: 84/100 = $33,750/x.

Cross multiplying gives us 84x = $33,75000.

Dividing both sides by 84,

we find that x = $40,178.57.

  If 18,600 is 31% of X then X x .31 = 18,600 

Then solve for X 

18,600 / .31 = 60,000 

Then check your answer: 

31% of 60,000 is 60,000 x .31 = 18,600
