Answer:
$180
Step-by-step explanation:
1. Find the perimeter: 2w + 2L
2(4) = 8 + 2(5) = 10
8 + 10 = 18 feet of fencing
2. multiply the cost per foot (10) by the number of feet (18)
10*18 = 180
Answer:
$2.5
Step-by-step explanation:
4 people went to the movies and spent $ 38 ( 9.50* 4= 38) since 48-38 = 10
they totally have 10 dollars left. 10/4 = 2.5 They each $2.5 left
Answer:
(3 (pm) sqrt(7))/2
Step-by-step explanation:
First step: Identify a,b, and c
a=2
b=-6
c=1
Second step: Find b^2-4ac (this is called the discriminant-I will call this D)
(-6)^2-4(2)(1)=36-8=28
Third step: Find the square root of the discriminant aka sqrt(D)
sqrt(28)
Let's see if we can simplify sqrt(28)
Here is there a factor of 28 that is a perfect square? How about 4? Yep!
sqrt(28)=sqrt(4)sqrt(7)=2sqrt(7).
Fourth Step: What is -b? If b=-6 then -b=6.
Fifth step: What is 2a? 2(2)=4
So the formula is
x=(-b (pm) sqrt(D))/(2a)
or
x=(step4 (pm) step 3)/(step 5)
x=(6 (pm) 2sqrt(7))/4
Simplify
x=(3 (pm) sqrt(7))/2
*pm means plus or minus
*sqrt( ) means square root of the number that follows in the ( )
Hi there! So, $2.97 is made for every toy Carl King assembles. He assembles 207 toys. To find out the amount of pay made per week, all you have to do is multiply 207 by 2.97, because of the amount of toys made and the price per toy made. 207 * 2.97 is 614.79. There. Carl King's total pay for a week is $614.79. The answer is D.
