Answer:
Yes,
You need 88 points.
Step-by-step explanation:
What you need to do here is to set up an equation using algebra (I do this in my master's degree to determine my grade).
= 400
x = 320
Your target required points is 320.
320 - 232 = 88 points.
You need 88 points on the exam to get the 80%.
Divide both sides by -2
-2(2x-1)=3x+16
distribute
-4x+2=3x+16
add 4x to both sides
2=7x+16
minus 16 from both sides
-14=7x
divide both sides by 7
-2=x
Step-by-step explanation:
C =2pi*(d/2) A = pi (d/2)^2
Part A
A B
25.12 = 2pi *(8/2) 9.42 = 2pi (3/2)
25.12 = 8pi 9.42 = 3pi
pi = 25.12 / 8 pi = 9.42 / 3
pi ≈ 3.14 pi = 3.14
Part B
A B
50.24 = pi (8/2)^2 7.065 = pi (3/2)^2
50.24 = pi *4^2 7.065 = pi (9/4)
50.24 = 16 pi 7.065 ( 4/9) = pi
50.24/16 = pi pi = 3.14
pi = 3.14
Part C
We see that pi is the constant ≈ 3.14
The volume of the prism is A!
Answer:
X = 12.21
Step-by-step explanation:
Since this is a right triangle, use the formula A^2 + B^2 = C^2 and plug in appropriate values.
(10)^2 + (7)^2 = C^2
100 + 49 = C^2
149 = C^2
12.2065 = C
Rounded to two decimal places, this makes X equal to 12.21.
