Answer:
the range of possible values for x are 1.6<x<9.6
Step-by-step explanation:
Answer:
146
Step-by-step explanation:
730 divided by 100 equals 7.3 and 7.3 times 20 equals 146
2015-2000=15 years
P=100,350,000×(1+0.017)^(15)
P=129,220,575.43
Her change will be $16.22 since 20 +20 is 40 and 40 - 23.78 is 16.22
Answer:
2√46 + 25π/4 ≈ 33.2 . . . . m²
Step-by-step explanation:
The altitude of the triangle is given by the Pythagorean theorem. The right triangle of interest is the one that has 5√2 as its hypotenuse, and a leg of half the base shown. Then the other leg, the altitude of the triangle, is ...
h = √((5√2)² - 2²) = √46
Then the area of the triangle shown is ...
A = (1/2)bh = (1/2)(4)(√46)
A = 2√46
__
The area of the semicircle is given by the formula ...
A = (1/2)πr²
Filling in the radius shown, the area is computed as ...
A = (1/2)π(5√2/2)² = 25π/4
So, the total area of the figure is ...
total area = triangle area + semicircle area
= 2√46 + 25π/4 . . . square meters
≈ 33.2 . . . square meters
