34 = - (m + 3) \\ 34 = - m - 3 \\ 37 = - m \\ m = - 37
First, we factor the - into the parentheses.
Then we add 3 to both sides.
Then we multiply both sides by -1.

The negative sign outside the parentheses represents –1. Distribute the –1 to everything inside the parenthesis. Use the addition property of equality first to add 3 to both sides. Then use the division property of equality to divide both sides by -1.

Which two angles in the figure are obtuse angles?
ValentinkaMS [17]

Answer: C. ∠SQP and ∠TQR

Step-by-step explanation:

Since, by the given diagram,

m∠TQR  = m∠SQP (vertical angles)

And, m∠TQP < m∠TQR

By adding ∠TQR on both sides,

m∠TQP + m∠TQR < m∠TQR+m∠TQR

⇒m∠TQP + m∠TQR < 2 ∠TQR

⇒ 180° < 2 m∠TQR ( Because ∠TQP and ∠TQR are linear angles)

⇒ 90° < m∠TQR

Hence ∠TQR is a obtuse angle,

⇒  ∠SQP also is a obtuse angle.

a construction company poured a cylindrical shaped concrete column 15 feet long with a radius of 3 feet. How much concrete did i
Vinil7 [7]

<u>Answer:</u>

The volume of cylinder in terms of π is 135\pi cubic feet

<u>Explanation:</u>

Given the radius of the cylindrical shaped concrete column is 3 feet

Height of the column is 15 feet

The volume of a cylinder is calculated by the formula;

V = \pi r^2h, where

r is the radius and h is the height

Substituting the values,

V = \pi \times (3)2\times (15)

V = \pi \times 9\times 15

V = \pi \times 135\\V = 135\pi

Hence, the volume of cylinder in terms of π is 135\pi cubic feet

A young equestrian loved to ride her horse all day long, dreaming of the day she would ride in the kentucky derby. one day in ea
podryga [215]
Poor family could afford a horse and a scooter but not a cellphone. Kidding aside, The girl had a two-hour head start, and was riding her horse at 10 mph. Her father was riding his scooter at 15 mph. As they will meet up, their distances would be the same. Looking at the formula for distance: distance = speed*time, we can equate the distance for the two people as they would be the same. This is shown below:

Let: x = number of hours

distance of girl = distance of dad
10(x + 2) = 15x
x = 4

Therefore, they will meet after 4 hours after 12:00pm, or at 4:00 pm.
