what is the value of q?

Answers

Answer: q=70°

Step-by-step explanation: 52°+58°+q=180°

next q=180°-110°

so q=70°

Q=70

52+58 gives you 110.

180 is the half of a full rotation, so the straight line is 180 degrees.

180-110 would give you 70 degrees.

Solve for m. m + 4 3 = 2 what is m
HELP MEEEEE!!!!!!!!!!!

Answers

hi there user! Looks like your looking for help, so Mizuki came here to help you!

the answer is:

m is 2/3

The whole work I did:

m + 4 ÷ 3 = 2

m + 4/3 = 2

m + 4/3 - 4/3 = 2 - 4/3

m = 6/3 - 4/3

m = 2/3

Anyways hope this helped! qwq

can i have some helpWhat is the perimeter of this composite shape? ___ ft.Use 3.14 for "pi" and round

Answers

Answer:

36.85 ft

Step-by-step explanation:

3 feet on either end + 6 feet on either side + circumference of the circle

3 + 3 + 6 + 6 + circumference of the circle

18 + circumference of the circle

You can find the circle's diameter by subtracting 6 from 12.  You get 6.  You can find the radius by dividing the diameter by 2.  You get 3.

The formula for circumference is 2·π·Radius

2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

I hope this helps!

2. y = 150x

3. y = 21x

Two variables are said to be proportional if as one variable increases, the other variable increase or vice versa.

Proportional relationship is in the form:

y = kx

where k is a constant.

Hence the equation in the form y = kx, that represent a proportional relationship is:

2. y = 150x

3. y = 21x

Answer:

D) None of the above

Step-by-step explanation:

Let's use process of elimination!

A) Vertical angles are opposite angles formed by two intersecting lines. These two are adjacent, therefore rendering this statement false.

B) Complementary angles are two adjacent angles that add up to 90 degrees. There is no proof that m∠a+∠b=90°, therefore this statement is false.

C) Supplementary angles are two adjacent angles that add up to 180 degrees. Assuming A∈ED, this statement is false as well.
