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!

If the simple interest on $1000 for 9 years is $630, then what is the interest rate?
Answers
Answer:
0.07 or 7%
Step-by-step explanation:
I = Prt
630 = (1000)(9)r
630 = 9000r
r = 0.07
Step-by-step explanation:
Simple interest (SI) = $ 630
Time (T) = 9 years
Principal (P) = $ 1000
Rate (R) = ?
We know
[tex]si = \frac{ptr}{100} \\630 = \frac{1000 \times 9 \times r}{100} \\ 630 = 90r \\ r \: = \frac{630}{90} \\ = 7\%[/tex]
Therefore the rate of interest is 7%.

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.

At a flea market, used computer games are sold at the prices shown in the table below.
Number of Games Price ($)
2 9.00
5 22.50
7 31.50
Answers
The proportion relation between the number of games and the price is given by the proportionality constant k = 4.5
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the number of games be represented as x
Let the cost for the total number of games be y
And , the values of x = { 2 , 5 , 7 }
Now , the values of y = { 9.00 , 22.50 , 31.50 }
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
On simplifying , we get
9 = k ( 2 )
Divide by 2 on both sides , we get
k = 4.5
And , 22.50 = k ( 5 )
Divide by 2 on both sides , we get
k = 4.5
Therefore , the proportionality constant is k = 4.5
Hence , the proportion is y = 4.5x
