Answer:
V = 10.5 ft³
Step-by-step explanation:
Volume formula: length x width x height
We are given all 3, so all we have to do is multiply them all together, When we plug it into the calc, we should get 21/2 or 10.5 ft³ as our answer.
Answer:
9 and -4
Step-by-step explanation:
change the word form to math form so now
x² - 36 = 5x <u>This look like a factoring problem, so we put it equal to 0</u>
x² - 5x - 36 = 0 <u>Now factor</u>
(x - 9) (x + 4) <u>We have to find 2 numbers that give -36 when we multiply and -5x when we add</u>
x - 9 = 0
x = 9
x + 4 = 0
x = -4
you can check by plugin the x value to actual equation.
the answer is 113.3Repeating
Answer:
86
Step-by-step explanation:
Firstly,
Average = Sum/Number of Numbers
Since 7 grades' average is 77, so we can say:
77 = Sum/7
Hence, Sum = 77 * 7 = 539
Now,
81 - 18 = 63 [63 marks were recorded incorrectly. actual sum would be 63 more]
So,
Actual Sum should be 539 + 63 = 602
Actual Average = 602 / 7 = 86
Hence, actual report card average would be 86
