Answer:
a) 84π b) 109.2π
Step-by-step explanation:
The formula to find this is v=πr^2h/3
r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.
252/3=84
and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π
B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.

Solve the system of equations using the substitution method. 2x+y=8
y=x-1
Answer:
x=3
Step-by-step explanation:
If we know that y=x-1, we can just substitute it and replace y with (x-1)
so 2x+y=8 becomes:
2x+(x-1)=8 and we simplify that into:
3x-1=8, add 1 on both sides to make it:
3x=9, divide 3 on both sides
x=3

Find the length of AB.
Answer:
We know that in a triangle, if two angles have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units
Answer:
AB=9
Step-by-step explanation:
[tex]\frac{DC}{BC}=\frac{EC}{AC}\\ \frac{4}{3}=\frac{16}{AC}\\\\ AC=12\\\\ AB=AC-BC\\ AB=12-3=9[/tex]

A tissue is 6 inches long the area is 24 in.² what is the width of the tissue
Answer:
4 In.
Step-by-step explanation:
If you 24 divided by 6 you would get 4. The equation to find area is L x W (length x Width). You're missing the width so you would just start from the area divided by length.
The area of the hardscape is 3x^2 + 13x + 4. what is the length and width of the hardscape
Answer:
[tex](3x+1)[/tex]
[tex](x+4)[/tex]
Step-by-step explanation:
Assuming that the given surface is two-dimensional, one can simply factor the given polynomial to find the dimensions of the surface.
[tex]3x^2 + 13x + 4[/tex]
Just by looking at the polynomial, it is fairly obvious that the factors are;
[tex](3x+1)(x+4)[/tex]
One can check this by distributing, multiply every term in one of the parenthesis by every term in the other. Then combine like terms,
[tex]3x^2 + 12x + x + 4\\\\3x^2 + 13x + 4[/tex]
Without further information, it is impossible to determine which is the length, and which is the width, one just knows that the dimensions of the surface are;
[tex](3x+1)\\\\(x+4)[/tex]

Find four consecutive multiples of three that the product of the first and third miners minus eight times the fourth number is negative 48
Answer:
The four consecutive multiples of three are 6, 9, 12, and 15
Step-by-step explanation:
let the first multiple of 3 = n
second multiple of 3 = (n + 3)
third multiple of 3 =(n + 6)
fourth multiple of 3 =(n + 9)
product of the first and the third = n(n + 6) = n² + 6n
eight times the fourth number = 8(n + 9) = 8n + 72
The difference between the two = n² + 6n - (8n + 72) = -48
n² + 6n - 8n - 72 = -48
n² - 2n = -48 + 72
n² - 2n = 24
n² - 2n - 24 = 0
n² - 2n - 24 = 0
n² + 4n - 6n - 24 = 0
n(n + 4) - 6(n + 4) = 0
(n - 6)(n + 4) = 0
n = 6 or - 4
n should be a positive number, thus n = 6
The second multiple of 3 = (n + 3) = 6 + 3 = 9
The third multiple of 3 =(n + 6) = 6 + 6 = 12
The fourth multiple of 3 = (n + 9) = 6 + 9 = 15
