Question 4 Multiple Choice Worth 6 points)

Mathematics
1 answer:
Kryger [21]3 years ago

Answer:

50°

Step-by-step explanation:

The diagram shows the arc RQ with the measure of 80°, this means the central angle ROQ (where O is the center of the circle) has the same measure of 80°. Angle QPR is inscribed angle subtended on the arc RQ. Its measure is half of the measure of the central angle QOR, so

m\angle QPR=\dfrac{1}{2}\cdot 80^{\circ}=40^{\circ}

In right triangle PQR, the sum of two acute angles is 90°, so

m\angle QPR+m\angle PQR=90^{\circ}\\ \\40^{\circ}+m\angle PQR=90^{\circ}\\ \\m\angle PQR=90^{\circ}-40^{\circ}\\ \\m\angle PQR=50^{\circ}

Denise and Stacey went to a carnival. The admission fee was $6 per person. Each ride at the carnival costs c dollars. The game b
evablogger [386]
The correct answer is D. 14c + 5g + 12.

The entry fee is $6 each. 6 + 6 = 12
Each girl goes on 7 rides which cost c dollars. 7c + 7c = 14c
The number of games both girls play totals 5. And each game costs g dollars. 2g + 3g = 5g.

Add all the costs up and you get 14c + 5g + 12 as their total cost for going to a carnival.

The cost of providing water bottles at a high school football game is $35 for the rental of the coolers and $0.50 per bottle
zloy xaker [14]

The cost function is an illustration of a linear function

The equation of the cost function is C(x) = 35 + 0.5x

The given parameters are:

Rentals = 35 -- the cost of renting a cooler

Rate = 0.5 --- the rate per bottle

Assume the number of bottles in a cooler is x.

The cost function for the bottles in a cooler would be:

C(x) = Rentals + Rate \times x

So, we have:

C(x) = 35 + 0.5\times x

Evaluate the products

C(x) = 35 + 0.5x

Hence, the equation is C(x) = 35 + 0.5x

The circumference C of a circle is equal to the product of π and the diameter d.
Lelu [443]

C=3.14 • d

3.14 is pi as a number but it’s non ending :3

D is diameter

C is circumference

Since it said the product of pi and diameter it means d or diameter times pi is c or circumference.

So if

D= i don’t n know maybe 5 find what’s c or te circumference.

So 5 multiplyed by pi or 3.14 is your circumference!

If u need help with the problem please don’t hesitate to ask me! And am purely her to help!!! :3
