Answer:
214 ft^3
Step-by-step explanation:
Here, we are asked to calculate the volume of the cylindrical construction pipe.
Mathematically, the volume V
V = pi * r^2 * h
r is radius = diameter/2 = 4/2 = 2 ft
h = 17ft
pi = 3.14
Putting these values, we have;
V = 3.14 * 2^2 * 17 = 213.52 which is 214 ft^3 to the nearest whole number

Answer:
y + 2 = -2(x - 3)^2
Step-by-step explanation:
We can see immediately that the vertex is at (3, -2).
The vertex form of the equation of a parabola is
y - k = a(x - h)^2.
If the parabola opened upward, the equation would be y + 2 = 2(x - 3)^2. But seeing that this particular parabola opens downward, the equation is
y + 2 = -2(x - 3)^2.
Check: Does the point (2, -4) satisfy this equation?
-4 + 2 = -2(2 - 3)^2 becomes -2 = -2(-1)^2, which is true.

what is the surface area of a cone in terms of pi with a diameter of 14cm and a slant height of 20cm
Answer:
476 Pi cm^2
Step-by-step explanation:
The surface area of a cone is given by the formula:
● Sa = Pi× r^2 + Pi×r×l
r is the radius and l is the slant heigth.
■■■■■■■■■■■■■■■■■■■■■■■■■■
We are given that:
● r = 14 cm
● l = 20 cm
Let's calculate Sa
● Sa = Pi×14^2 + Pi × 14 × 20
● Sa = 476 Pi cm^2

Answer:
[tex]\boxed{\sf \ 48 \ }[/tex]
Step-by-step explanation:
Hello,
the sum of all angles of the triangle at the left must be 180
so the last one is 180 - 80 - 60 = 40
and then the angle at the bottom left of the second triangle is 180 - 40 -72 = 180 - 112 = 68
and then the angle that we have to find is 180 - 64 - 68 = 48

what number is not part of the solution set to the inequality below?
w - 10 less than or equal to 16
Answer:
If you have this as an answer, 27
(The question is "what number is not part of the solution set to the inequality below?)
Step-by-step explanation:
w - 10 ≤ 16
w - 10 + 10 ≤ 16 + 10
w ≤ 26
11, 15, and 26 are all either less than, or equal to 26. Only 27 is not.
f(x) = x ^ 2 + 6x - 4 in vertex form
Answer:y=(x-6)^2-4
Step-by-step explanation:
Answer:
f(x) = (x + 3)² - 13
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
Given
f(x) = x² + 6x - 4
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = x² + 2(3)x + 9 - 9 - 4
f(x) = (x + 3)² - 13 ← in vertex form

Gracie has 1/2 of a cantaloupe that she wants to divide. How many 's 1/8 of a cantaloupe are there in 1/2 of a cantaloupe?
Answer:
4/8
Step-by-step explanation:
Dividing a whole cantaloupe into eighths will give you 8/8 or 1. When it is cut in half then divided there is one half of 8/8 or there are 4/8 in one half. This is true because 1/2 and 4/8 are equal terms.

Answer:
Answer is A
Step-by-step explanation:
(14x^4y^6)/(7x^8y^2)
because everything is one term, you can split into three terms
14/7, x^4 / x^8 , and y^6/y^2
multiplying these three terms will get us the starting term
14/7 = 2
x^4 / x^8
with division of exponents, you subtract the smaller exponent (4), from the big exponent (8), and leave it on the same side (bottom) as the big exponent
1/x^4
same thing with our y's
y^6/y^2
this time, the term stays on the top
y^4
take the simplified terms and multiply them together
(2) * (1/x^4) * (y^4) =
A: (2y^4) / (x^4)

The bottom part of this block is a rectangular prism. The top part is a square pyramid. You want to cover the block entirely with paper. How much paper do you need?
Answer:
Total paper required = 165 cm²
Step-by-step explanation:
Paper required to cover the entire block = (Surface area of the prism at the base - area of the top of the prism) + Lateral surface area of the pyramid
Surface area of the rectangular prism = 2(lb + bh + hl)
(here l, b, h are the length, width and height respectively)
= 2(5×5 + 5×4 + 4×5)
= 2(25 + 20 + 20)
= 2×65
= 130 cm²
Area of the top of the prism = (side)²
= 5²
= 25 cm²
Lateral area of the square pyramid = 4 × Area of one lateral side
= 4 × [tex][\frac{1}{2}(\text{Base})(\text{Height})][/tex]
= 4 × [tex][\frac{1}{2}(5)(6)][/tex]
= 60 cm²
Total paper required = (130 - 25) + 60
= 105 + 60
= 165 cm²
What is equivalent to log2(7)
A.7^2
B.2^7
C.7log(2)
D.log(7)/log(2)
E. Log(2)/log(7)
Answer:
D
Step-by-step explanation:
Using the changing base formula, log base 2 raised to 7 can be written as log7/log2
The correct answer is D. log(7) / log(2).
To find the equivalent of log2(7), you can use the change of base formula for logarithms.
The change of base formula states that log base a of b is equal to log base c of b divided by log base c of a.
In this case, we want to find the equivalent of log2(7), so we can use the change of base formula with base 10 as follows:
log2(7) = log(7) / log(2)
Therefore, the correct answer is D. log(7) / log(2).

Answer:
We need a non-included side of one triangle
Step-by-step explanation:
By means of the AAS postulate.
The Angle-Angle-Side postulate (AAS) tells us that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

If two sets of data have the same mean, they must be the same set of data.
Answer:
opinion
Step-by-step explanation:
2 different sets of data can have the same mean:
for example
4, 5, 6 ---> has a mean of 5
2,6,7 ---> also has a mean of 5
hence it is NOT a fact that if the means are the same, that it must be the same data set
