Using the SA formula you'll have to substitute in the edge length for s.
SA = 6(312)²
SA = 584064
The surface area is 584,064 feet²
Hope this helps :)
To calculate the average you add up all the scores and divide by the number of scores (5)
add all the current test scores and allow X to be the unknown score:
92+80+88+93+X: or 353 + X
set up equation:
(353+X)
______ = 90
5
Multiply both side of the equation by 5 to clear the fraction resulting in:
353+X=450
Subtract 353 from both sides of the equation:
x = 97
So the test score needed to get a 90 average is 97.
Answer:
114
Step-by-step explanation:
Add all the angles displayed and add 90 degrees because we can see one of the angles is a right angle, Now take the total and subtract 540 with the sum and you will get 114 which is your answer.
Answer:
(0,8)
Step-by-step explanation:
To get the y-intercept put all x values equal to 0 (because we want to see where y lies on the graph when x is zero.
y=2^0+3
y=2^3
y=8
The y-intercept is (0,8)
As for the rest of the answers.....
1)A) 2
-5
= 4
-5
so the final answer is -![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
1B) the problem is (3-
)(3+
) a quick formula to help you solve this type of problem is (a-b)(a+b)= a^2-b^2 so you transform the question to 3^2-
^2
to get 9-7 which is 3 therefore the final answer is 3
2) when you transform a function from y=x^2-3 to y=x^2+1 the graph moves 4 units up. So the final answer is b)4 units up
Question 3a and 3b are correct
IM NOT A BOT I SWEAR.
