8 pencils = 1 package
28 children need pencils
Each child gets 4 pencils
28x4 = 112 (pencils needed)
112/8 = 14 packages needed.
15.1 is close to 14 so then you have 14/7 which approximately = 2
Answer: 1 1/4feet
Step-by-step explanation:
From the question, we are informed that the depth of the water in the pool changes by −3/4 foot every hour and that the depth of the water was 5 feet when she started draining.
The depth of the water after 5 hours will be:
= 5 - 3/4(5)
= 5 - 15/4
= 5 - 3 3/4
= 1 1/4 feet
Answer:
600,000 km²
Step-by-step explanation:
Using the exponential regression calculator : the regression fit obtained for the data is :
36510 * (1.08^x)
After 40 years ;
x = 40
Hence,
y = 36510 * 1.08^40
y = 36510 * 21.72452
y = 793,162.27 km
Hence, y is closest to 800,000 km
I assume the volume of the larger pyramid is 108 ft^3, not 108 ft^2.
The scale factor of edges of two solids is x.
The scale factor of their areas is x^2.
The scale factor of their volumes is x^3
The areas have a scale factor of 18/8 = 2.25
The length have a scale factor of sqrt(2.25) = 1.5
The volumes have a scale factor of 3.375
108/3.375 = 32
Answer: 32 ft^3
