Answer:
She could purchase from stores A, D and E.
Step-by-step explanation:
She needs 8 cups so I multiplied each price by 8;
Store A 0.49(8)=$3.92
Store B 0.51(8)=$4.08
Store C 0.55(8)=$4.40
Store D 0.48(8)=$3.84
Store E 0.45(8)=$3.60
The width is 6cm
And the length is two times + 3 of the width
6 X 2 + 3 = 15
Add all 4 sides for the perimeter 6+6+15+15=42
The the dimensions are a rectangle that is 6cm wide and 15cm tall
Answer:
7 inches
Step-by-step explanation:
The volume of a cylinder is calculated using
where r =4 inches is the radius and V=351.68 is the volume.
To find the height of the jar, we substitute these values and solve for h.
Divide both sides by 50.24 to get:
h=7 inches
Therefore the height of the jar is 7 inches
Answer:
153,997 Labrador Retrievers
Step-by-step explanation:
Let's make an equation for this problem. We know that there were 9,860 Great Danes. The number of Labrador Retrievers was 6,997 more than 15 times the number of registered Great Danes. More than can be changed to a plus sign. 15 times the number of Great Danes is 15 times 9,860. The equation is now 15*9,860 + 6,997.
15*9,860 is 147,900
147,900 + 6,997 is 153,997.
Answer:
57.5
Step-by-step explanation:
The constant of proportionality is "k" in the equation ...
y = kx
It can be found from values of x and y using ...
k = y/x
For the given values, it is ...
k = (287.5 mi)/(5 h) = 57.5 mi/h
The constant of proportionality relating miles to hours is 57.5.
