Greg earns $14 per hour at his office job, along with a $25 weekly bonus. The following inequality represents his earnings on hi

Neporo4naja [7]

Answer:

Greg worked more than 20 hours.

Step-by-step explanation:

Let's solve the inequality for $h$ so we know how many hours Greg worked:

Step 1. Subtract 25 from both sides of the inequality

$14h+25>305$

$14h+25-25>305-25$

$14h>280$

Step 2. Divide both sides by 14

$\frac{14h}{14} >\frac{280}{14}$

$h>20$

We can conclude that Greg worked more than 20 hours.

An electrical pole is 12.4m tall. It is supported by a guy wire that is 17.3 long. how far is the anchor of the guy wire to the

kari74 [83]

The anchor of the guy wire is 12.06 meters away form base of electrical pole.

Further explanation:

The whole given scenario forms a right angle triangle. The pole is standing straight so it is the perpendicular while the guy wire goes from the top of pole to the anchor so it will be the hypotenuse. We have to finds the base.

Pythagoras theorem will be used.

Pythagoras theorem states that:

$H^2=B^2+P^2$

Given

Base=?

Perpendicular=12.4 m

Hypotenuse = 17.3 m

Putting the values

$(17.3)^2=B^2+(12.4)^2\\299.29=B^2+153.76\\B^2=299.29-153.76\\B^2=145.53\\Takeing\ Square\ root\ on \both\ sides\\\sqrt{B^2}=\sqrt{145.53}\\B=12.06\ m$

The anchor of the guy wire is 12.06 meters away form base of electrical pole.

Solve X²-5X-14=0 using quadratic formula

il63 [147K]

Answer:

x=-2 or x=7

Step-by-step explanation:

X²-5X-14=0 find the factors of -14x² which is -7x and +2x

X² -7x + 2x - 14 = 0 factorize

x(x-7) + 2(x-7) = 0

(x+2)(x-7) =0

x+2 = 0 or x-7= 0

x=-2 or x=7
