30.625 cm2
49.625 cm2
61.25 cm2
Answers
square based pyramid = 3.5 cm base
side length = 7 cm
Base Area = (3.5cm)² = 12.25cm²
Surface Area = Base Area + 2sl = 12.25cm² + (2 * 3.5cm* 7cm)
S.A = 12.25 cm² + 49 cm²
S.A = 61.25 cm²
Answer:
The answer is C, 61.25

The total number of boxes that Marnie had to pack was 25.
What are percentages?
A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Marnie packed 18 boxes in 3 hours, which was 72% of the total number of boxes she had to pack.
Let the total number of boxes that she packed is x then we have
72/100 ×x=18
x=18×25/18
x=25
Hence, The total number of boxes that Marnie had to pack was 25.

let the total number be x.
72% of the total number = 18
(72/100)*x = 18
0.72x = 18
x = 18/0.72
x = 25
So she had to pack 25 boxes. Option A.
Hope this explains it.

Answer:
The annual simple interest is 1.7%
Step-by-step explanation:
We are given I=$17, P=$500, t=2 years
Formula:
SI= PRT
where,
SI = Simple Interest (SI=$17)
P = Principle (P=$500)
R = Rate of interest (R=?)
T = Time (T=2)
Substitute the values into formula
17 = 500 x R x 2
R = 1.7%
Hence, The annual simple interest is 1.7%
