Solve the compound inequality<br> 3t-8/5 and 4-t<-7

Sav [38]

Answer: -2.8

Step-by-step explanation:

3t-(8/5) * 4-t < -7

(15t-8)/5 * 4-t < -7

((15t-8)(4-t))/5 < -7

(15t^2)-28t-32< -7

(15t^2)-28t-32-7< 0

(15t^2)-28t-39< 0

Using the quadratic/almighty formula

t= (-b +- ((b^2)-4ac)^(1/2)/2a)

a=15, b=-28, c=-39

t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))

t= -2.8 or t= 0.9

Since

t<0, then t= -2.8

A third of a number minus 8 is 17 What is the number

katrin [286]

Answer:

<h2>The number is 75</h2>

Step-by-step explanation:

Let the number be x

A third of a number is written as

$\frac{1}{3} x$

A third of a number minus 8 is written as

$\frac{1}{3} x - 8$

The result is 17

We have

$\frac{1}{3} x - 8 = 17$

<u>Add 8 to both sides of the equation</u>

That's

$\frac{1}{3} x + 8 - 8 = 17 + 8 \\ \frac{1}{3} x = 25$

<u>Multiply through by 3 to eliminate the fraction</u>

That's

$3 \times \frac{1}{3} x = 25 \times 3 \\ x = 2 5 \times 3 \\ x = 75$

<h3>The number is 75</h3>

Hope this helps you

3. A children's slide is 10 feet long and inclines 64° from the ground. The

Nata [24]

Answer:

87.0°

Step-by-step explanation:

The law of sines can be used to solve this. We have two sides of a triangle and the angle opposite one of them. We want to find the angle opposite the other known side.

In the attached, the triangle is ΔACS. We have side "a" = 9, and side "c" = 10. Angle A is given as 64°. The law of sines tells us ...

sin(C)/c = sin(A)/a

sin(C) = (c/a)sin(A)

C = arcsin((c/a)sin(A)) = arcsin(10/9·sin(64°)) ≈ 87.03°

The ladder makes an angle of about 87° with the ground.
