The head of a nail is circular, as shown. The head of this nail has a diameter of 6 millimeters. Which measurement is closest to the area of the head of this nail in square millimeters?
Answers
Answer: [tex]\boxed{\ 28.26}[/tex]
My step-by-step explanation:
We would use the formula πr2 (pi x radius x radius)2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2
And so we find: 6mm÷2=3mm3. So now that we have our radius, we can just plug the numbers into the formula. So this would be:
πr2= 3.14 x 3 x 3= 28.26mm2Hope this helps you!

A school counselor surveyed 90 randomly selected students about the languages they speak. Of the students surveyed, 15 speak more than one language fluently. Based on these results, how many of the 1,800 students at the school can be expected to speak more than one language fluently? A.288 B.300 C.113 D.389
Answers
Answer:
b
Step-by-step explanation:
Because the population is too large and it would be impractical to survey the whole population, a sample of the population is chosen to take part in the survey. This sample is taken as been representative of the whole population
Based on the sample, the fraction of students that speak more than one language fluently = 15/90= 0.166667
Population that would speak more than one language fluently = 0.166667 x 1800 = 300

Answers
Answer:
<QRS = 55 degrees
Step-by-step explanation:
Given the following
m∠QRS=(10x−1) ∘
∠RPQ=(3x+17) ∘
m∠PQR=(2x+12)
External angle m<QRS = 10x-1
Interior angles are m∠RPQ=(3x+17) ∘ and m∠PQR=(2x+12)
Using the law that the sum of interior angle is equal to exterior
10x + 1 = 3x+17 + 2x + 12
10x+1 = 5x+29
10x-5x = 29-1
5x = 28
x = 28/5
x = 5.6
Get m<QRS
Recall that <QRS = 10x - 1
<QRS = 10(5.6) - 1
<QRS = 56-1
<QRS = 55 degrees

Working at papa rons pizza you make 30 per shoft plus 3 per pizza you deliver. If you worked gor bombinoes you eould make 20?Per shift snd 4 per pizza you delivers. How many pizzas do you have to deliver to earb the same amount of money
Answers
Answer: 10 pizzas
Step-by-step explanation:
To answer this you need to equate the formulas of the money earned from both pizzerias.
Assume number of pizzas is x:
Papa rons:
= 30 + 3x
This is the amount one gets for delivering a certain number of pizzas
Bombinoes
= 20 + 4x
Equate them:
30 + 3x = 20 + 4x
30 - 20 = 4x - 3x
x = 10
10 pizzas would earn you the same amount of money.
