Answer:
Option B 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The perimeter of the figure is equal to sum the length of semicircle plus the length of three sides of a square
<u>Find the length of semicircle</u>
Remember that the circumference of semicircle is equal to
we have
substitute
The perimeter of the figure is equal to
The amount of different ways possible can be shown by 7!=5040 Im pretty sure.
Answer:
There Is no problem.
Step-by-step explanation:
I would love to help you once you add a question. Have a blessed day!
8. The percentage of salt in each mixture is 0.35%.
To find out the latter part of the problem, we can use algebra:
14 (grams of salt) = 0.35m (0.35% of the mixture)
14 ÷ 0.35 = 0.35m ÷ 0.35 (we want to find just m, so we have to divide it by 0.35)
40 = m. The scientist made 40 g of mixture!
9. We just divide 32.5 pounds by 0.25 ( a quarter).
32.5 ÷ 0.25 = 130 kids!
10. Her original distance is 0.5 miles. But! She walked back 0.25 (quarter) mile so now this adds a quarter of a mile of distance from her house to her school.
0.5 × 3 = 1.5 + 0.25 = 1.75 miles from her house to her school.
