Answer:
It would require 40 teaspoons
Step-by-step explanation:
Given that;
A cookie recipe requires 3 teaspoons of baking soda for 36 cookies
The amount of teaspoons of baking soda required per cookie is;
r = 3/36 teaspoons per cookie
So, for 480 cookies i would require;
N = r × 480 cookies
Substituting r, we have;
N = 3/36 teaspoons per cookie × 480 cookies
N = 40 teaspoons
It would require 40 teaspoons
First we need to find out the volume of one cylinder. We already know the volume of the block of gold is 360cm3
V = Pie * radius squared* height.
Pie is 3.142
radius is 6.18/2 = 3.09 cm
height is 6cm
V = 3.142 * 3.09 * 3.09 * 6
V = 180cm3
Now we divide the volume of this cylinder with the volume of block of gold.
360/180 = 2
So it will take 2 cylinders to mold one block of gold.
Answer:
10
Step-by-step explanation:
3+2=5+26=31+9=40/4=10
6.25 times 3 is 18.75
7.50 times 3 is 22.5
1.25 times 6 is 7.5
Add those and you get 48.75.
48.75 times .045 is 2.19
48.75 times .15 is 7.31.
Add the tax and tip to the value, you get $58.25.
The percent error in Marcela's estimate is 612÷735=8.3%.
The actual speed of the car is either 57 mph or 63 mph. (60×0.05=3, 60-3=57 mph or 60+3= 63 mph)
