help with (b) I had ended up with 7234.56 . . . but it came out incorrect...
V = (4 / 3) π r3
= (4 / 3) • 3.1416 • (6 ft)3
= (4 / 3) • 3.1416 • 216 ft3
= 904.7808 ft3
You got 7234 because you cubed the diameter instead of the radius.
.
Write the phrase as an expression:
X
The quotient of a number x and the sum of 3 and 7. ––––––
3 + 7
200
17 less than the quotient of 200 and a number y. ––––– – 17
Y
15w – 9 = 2w + 5
15w – 2w – 9 = 2w – 2w + 5
13W – 9 = + 5
13W – 9 + 9 = + 5 + 9
13W = + 14
13W 14
–––– = ––––
13 13
W = 14 / 13
W = 1 1/13
An 8 digit number X has one 2, three 3's, two 4's, and two 5's.
X can be expressed as a power of 2. Find value X
X = 225 = 33,554,432
I admit this was too hard for me. I had to get help.
what can 15 be divided by except 3
Fifteen can be divided by any number at all, except zero.
If you mean divided evenly, the factors are 1, 3, 5, & 15.
what is 0.95m=________ft

what is IaI=9.5 the "i" is for abouslute vaule
If the absolute value of a is 9.5, then a = + 9.5
That's read as "plus or minus nine point five".
If there's an input-output table such as:
INPUT: 7, -1, 11 OUTPUT: 2,-6,6
What is the input-output rule?
Input Output
7 2
–1 –6
11 6
In this specific example, the rule was subtract 5.
