B is the answer; 0.147 and 0.4 are both repeating. Repeating decimals can be turned into fractions. Therefore, this would be a rational number!

What is the measure of angle A in the triangle?<br> Enter your answer in the box.<br> mZA=

stepladder [879]

Answer:

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

A + B + C = 180

2x-10 + 70+ x+30 = 180

Combine like terms

3x +90 = 180

Subtract 90 from each side

3x+90-90=180-90

3x= 90

Divide by 3

3x/3= 90/3

x=30

We want to find angle A

A = 2x-10

=2*30 -10

=60-10

Suppose a flare is shot from the top of a 120 foot building at a speed of 160 feet per second. The equation h = ?16t + 160t + 12

insens350 [35]

Answer:

The time taken for the flare to hit the ground is approximately 10.7 seconds.

Step-by-step explanation:

Given : Suppose a flare is shot from the top of a 120 foot building at a speed of 160 feet per second. The equation $h =- 16t^2+ 160t + 120$ models the h height at t seconds of the flare.

To find : How long will it take for the flare to hit the ground?

Solution :

The equation $h =- 16t^2+ 160t + 120$ models the h height at t seconds of the flare.

The flare to hit the ground when h=0.

Substitute in the equation,

$-16t^2+ 160t + 120=0$

Applying quadratic formula, $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Where, a=-16, b=160 and c=120

$x=\frac{-160\pm\sqrt{160^2-4(-16)(120)}}{2(-16)}$

$x=\frac{-160\pm\sqrt{33280}}{-32}$

$x=\frac{-160\pm 182.42}{-32}$

$x=\frac{-160+182.42}{-32},\frac{-160-182.42}{-32}$

$x=−0.70,10.70$

Reject the negative value.

Therefore, the time taken for the flare to hit the ground is approximately 10.7 seconds.
