Answer:
c.132
Step-by-step explanation:
so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**
but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**
so we have to divide 42/2 which equals 21
now we need to set up the formula;
c=2πr/c=2xπxr **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**
c=2π21
=131.946891451
and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132
good luck :)
i hope this helps
have a good one !!
Answer:
second option
Step-by-step explanation:
Given
x² - 6x - 33 = 0 ( add 33 to both sides )
x² - 6x = 33
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 33 + 9
(x - 3)² = 42 → second option
<u>Answer:</u>
<h3>(
) x (
) </h3>
<u>Step-by-step explanation:</u>
To find the area of a rectangle, we have to multiply the length with the width.
In the question, the given length is 'x' and the width given is 'x +7'
So, the area would be
( ) x ( )
The area = 
So, the equation to find the area of such a rectangle would be:-
( ) x ( )
Answer: The answer is C
Step-by-step explanation:
Answer:
C. 25x+12y+4≤ 130
Step-by-step explanation:
Each ticket cost $25, so x would be the number of tickets she has to buy.
25x
Each T-shirt cost $12, so y would be the number of T-shirts she can buy.
12y
And since there is an service fee for the entree purchase, that's another $4.
+4
The cost of everything has to be less than $130, so the equation would be:
25x+12y+4≤ 130
