Answer:

Step-by-step explanation:

perimeter=2(85)+π(12.5)=220+2×12.5π

=170+25×3.14

=170+78.5

=248.5

distance ran=3×248.5=745.5 yards.

Answer:

Step-by-step explanation:

d= 25 yards ;   r = 25/2 = 12.5 yards

circumference of two semicircle = circumference of circle

=  2πr = 2*3.14*12.5 = 78.5 yards

Perimeter of school truck  = 78.5 + 85 + 85 = 248.5 yards

Distance traveled by  Jasmine = 3* 248.5 = 745.5 yards

When Han makes chocolate milk, he mixes 2 cups of milk with 3 tablespoons of chocolate syrup. Here is a table that shows how to
Korvikt [17]

Answer:

Part a) The table shows a proportional relationship between tablespoons of chocolate syrup and cups of milk

Part b) The scale factor is 1.5

Part c) The constant of proportionally for this relationship is 1.5

Part d) The units for the constant of proportionality are tablespoons of chocolate syrup per cups of milk

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line

Let

x ----> the quantity of cups of milk

y ----> the quantity of tablespoons of chocolate syrup

k ---> the constant of proportionality

For y=3, x=2 -----> k=\frac{y}{x}=\frac{3}{2}=1.5

For y=12, x=8 -----> k=\frac{y}{x}=\frac{12}{8}=1.5

For y=3/2, x=1 -----> k=\frac{y}{x}=\frac{(3/2)}{1}=1.5

For y=15, x=10 -----> k=\frac{y}{x}=\frac{15}{10}=1.5

therefore

The table shows a proportional relationship between tablespoons of chocolate syrup and cups of milk

The linear equation is

y=1.5x

That means----> The the quantity of tablespoons of chocolate syrup is 1.5 times the quantity of cups of milk

The scale factor is equal to the ratio between tablespoons of chocolate syrup and cups of milk. Is equal to the constant of proportionality k

The scale factor is 1.5

The constant of proportionality is 1.5

The units for the constant of proportionality are tablespoons of chocolate syrup per cups of milk

\frac{tablespoons\ of\ chocolate\ syrup}{cups\ of\ milk}
