Answer: c) 0.6
<u>Step-by-step explanation:</u>
0 is not a success so that value is not included.
1 and 2 are successes so those values are added:
0.48 + 0.16 = 0.64
Rounded to the nearest tenth is: 0.6
Answer: 27g+12q-8qr+42d-90
Step-by-step explanation:
3(9g+8),-6(9-2q) -8(9r+6) and 6(-2+7d)
=27g+24-54+12q-8qr-48-12+42d
=27g+12q-8qr+42d-90
Answer:
Step-by-step explanation:
Answer:
You can check it by solving it in your head. They are separating at the rate of 55-40 or 15 miles per hour. So in 1 hour or 60 minutes they'll be 15 miles apart, so in 20 minutes they'll be 5 miles apart, so in 40 minutes they'll be 10 miles apart. So it has to be 40 minutes.
Step-by-step explanation:
55t-40t=10
15t=10
15t/15=10/15
2/3
40 Minutes
Answer:
The value of x is 4
Step-by-step explanation:
In a right triangle, if a segment is drawn from the right angle ⊥ to the hypotenuse like the given figure, then
∵ The length of one side of the right triangle = (x + 2)
∵ The length of the hypotenuse = x + 5
∴ (x + 2)² = x (x + 5)
∵ (x + 2)² = (x + 2)(x + 2)
∴ (x + 2)(x + 2) = x(x + 5)
→ Simplify the two sides
∵ (x)(x) + (x)(2) + (2)(x) + (2)(2) = (x)(x) + (x)(5)
∴ x² + 2x + 2x + 4 = x² + 5x
→ Add the like terms in the left side
∴ x² + 4x + 4 = x² + 5x
→ Subtract x² from both sides
∵ x² - x² + 4x + 4 = x² - x² + 5x
∴ 4x + 4 = 5x
→ Subtract 4x from both sides
∴ 4x - 4x + 4 = 5x - 4x
∴ 4 = x
∴ The value of x is 4
