On Monday, five friends: Jamie, Susie, Sissy, Sandy, and Tiffany all put their money together
for a United Way donation. Together they gave fifteen dollars and nine cents. Sissy gave
twice as much as Susie. Susie gave ten cents more than twice as much as Sandy. Tiffany
gave thirty cents less than Sandy while Jamie gave seventy-five cents less than four times
what Sandy put in.
How much money did each person contribute?

Answer:

A. 78.5m^2

Step-by-step explanation:

To find the area of a circle you have to do:

Area = πr^2

The diameter is 2.5 x 4 which equals 10 and radius is half the diameter, so 5. Now your equation would be:

Area = π5^2

Solve:

π x 5^2

5^2 = 5 x 5 = 25

π x 25

π ≈ 3.14

3.14 x 25 = 78.5

Answer:

π5^2 ≈ 78.5

78.5m^2

Answer:

1 1/4 cups

Step-by-step explanation:

Answer:

1 1/4 cups of punch.

Step-by-step explanation:

Since 2 1/2 cups of sherbet are needed to make 24 cups, and we need to make 12 cups of punch, it's basically 24 divided by 2. So we need to divide 2 1/2 by 2, which would be 1 1/4 cups.

Answer:

A. The equation of the line is y=−2.5x+10.

C. The y-intercept is k.

F. The value of k is 10.

Step-by-step explanation:

A line passes through points (0, k) and (4,0) and has a slope of –2.5. Which statements are true regarding the graph of the line?

A. The equation of the line is y=−2.5x+10.

B. The equation of the line is y=−2.5x.

C. The y-intercept is k.

D. The y-intercept is 4.

E. The value of k is 4.

F. The value of k is 10.

Solution:

The slope of a line is the ratio of the vertical change to the horizontal change. The slope (m) of a line passing through [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Given that the line passes through (0, k) and (4,0)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]-2.5=\frac{0-k}{4-0}\\\\-2.5=\frac{-k}{4}\\\\k=10[/tex]

The equation of the line is given as:

[tex]y-y_1=m(x-x_1)\\\\y-10=-2.5(x-0)\\\\y = -2.5x+10[/tex]

The y intercept is the value of y when x = 0, hence intercept = k

Given the line that passes through points (0, k) and (4,0) and has a slope of –2.5, we need to get the value of "k

The formula for calculating the slope of a line is expressed as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\-2.5 = \frac{0-k}{4-0}\\-2.5=\frac{-k}{4} \\Cross \ multiply\\-2.5 \times 4 = -k\\-10 = -k\\k = 10[/tex]

Hence the value of k is 10.

From the coordinate given (0, 10) and (4, 0), we can see that the y intercept and x intercept of the graph is 10 and 4 respectively

Step-by-step explanation:

This are the options:

A. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 4 equal parts.

B. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 8 parts.

C. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 5 equal parts.

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

Amount of Fabric owned by Louisa = 4 yards

If she uses 2/5 yards to make a doll dress, to get the number of dolls that 4 yards can make we will say:

1 doll = 2/5 fabric

x doll = 4 fabrics

Cross multiply

2/5 * x = 4*1

2x/5 = 4

cross multiply

2x = 20

Divide both sides by 2:

2x/2 = 20/2

x = 10

This means that she can make 10 dolls using 4 yards of fabric.

Hence the correct option will be

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

==================================================

Explanation:

Pick any two rows from the table to form (x,y) points

I'll select the first two rows.

(x1,y1) = (-4,-3) from row 1

(x2,y2) = (0,-2) from row 2

Plug those values into the slope formula

m = (y2-y1)/(x2-x1)

m = (-2-(-3))/(0-(-4))

m = (-2+3)/(0+4)

m = 1/4

The slope is 1/4, which is also the rate of change.

Answer:

All real numbers.

Step-by-step explanation:

If both sides, when simplified, equals each other, the answer will be "all real numbers". Simplify the left side. Distribute 2 to all terms within the parenthesis:

2(x + 1) = (2 * x) + (2 * 1) = 2x + 2

2x + 2 = 2x + 2 ∴ A) All real numbers is your answer.

• Area of rectangle = 120 m²

• Breadth = 8m

• perimeter of the rectangle .

As we know that ,

• Area of rectangle = L× B

=> 120 = L × 8

=> L = 120/8

=> L = 15

Length of the rectangle is 15m .

Now ,

• perimeter of rectangle = 2 (L+B)

=> perimeter of rectangle = 2 (15+8)

=> perimeter of rectangle = 2 ( 23)

=> perimeter of rectangle = 46

Hence, the perimeter is 46 m .
