Solve the following absolute value equation. −8 − 2 |5X – 17| = −14

Mathematics
1 answer:
Levart [38]2 years ago
4 0

If 5x - 17 ≥ 0, then |5x - 17| = 5x - 17 and the equation reduces to

-8 - 2 (5x - 17) = -14

-8 - 10x + 34 = -14

-10x = -40

x = 4

If 5x - 17 < 0, then |5x - 17| = -(5x - 17) = -5x + 17 and we have

-8 - 2 (-5x + 17) = -14

-8 + 10x - 34 = -14

10x = 28

x = 2.8

What is the volume of a hemisphere with a radius of 2.3 m, rounded to the nearest tenth of a cubic meter?
ANTONII [103]

Answer:25.5m^3

Step-by-step explanation:

radius(r)=2.3m

π=3.14

volume of hemisphere=2/3 x π x r^3

Volume=2/3 x 3.14x(2.3)^3

Volume=2/3 x 3.14 x 2.3 x 2.3 x 2.3

volume=(2x3.14x2.3x2.3x2.3) ➗ 3

Volume=76.40876 ➗ 3

Volume=25.5

If 60 is 75% of s value, what is that value
ohaa [14]
Let's write it down:
<span>"60 is 75% of s" means:

60=75%*s

75% is \frac{75}{100}= \frac{3}{4}, (percent just means "out of 100" so we just divide it by 100) so we can also write:

60=</span><span>\frac{3}{4}s

now, let's multiply both sides by 4:

240=3s

and divide by 3:
80=s

So we have the result that the original value, s, is 80!
