Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
Let x be the Annika's weekly income.
2/25 of x = 42
2x/25 = 42
x = 42(25/2)
x = 525
Her weekly income is $525.
Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y =
or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x=
≈ 22.4
Answer: 200
Explanation/Calculation: 6 (in the one's place) rounds to 10. So it would round up to ten. Therefore, the answer is 200.
