Answer:
V = 1077.566 units²
Step-by-step explanation:
Assuming this is a cylinder, the formula is (area of base) × (height)
or (πr²)(h), simply plug-in the given values:
= (π(7)²)(7)
= (153.938)(7)
V = 1077.566 units²
Answer:
x = 7
Step-by-step explanation:
Lets do the brackets first,
6 × 2x = 12
6 × -11 = -66
------
Calculate the x constant:
12x - 3x = 9x
-------
Then the ones with no x:
-66 + 15 = -51
51 + 12 = 63
-------
Lastly, divide
63 ÷ 9 = 7
-------
Have a good day :)
Answer:
What kind of geometry EX. 6th grade 7th grade 8th grade Eureka etc.
Step-by-step explanation:
Answer:
x =2
SK = 21
KY = 13
SY = 34
Step-by-step explanation:
we can see from the picture the following:
SK + KY = SY equation 1
SK=13x-5 equation 2
KY = 2x+9 equation 3
SY = 36-x equation 4
using equation 2, equation 3 and equation 4 in equation 1 we have:
13x - 5 + 2x + 9 = 36-x
15x +4 = 36 - x
15x +x = 36-4
16x = 32
x = 32/16
x= 2
using x as 2 we evaluate it in equation 2, equation 3 and equation 4:
SK=13(2)-5 = 21
KY= 2(2) +9 = 13
SY = 36-2 = 34
520*.04=20.8, or closer to 21 spam emails.
