Answer:
20 cubic feet.
From feet: length (ft) × width (ft) × height (ft) = cubic feet.
From inches: length (in) × width (in) × height (in) ÷ 1728 = cubic feet.
From yards: length (yd) × width (yd) × height (yd) × 27 = cubic feet.
If you need to convert to cubic feet from inches: divide the final number (i.e. the total you get after multiplying the three dimensions together

The graph shows a proportional relationship. Which equation matches the graph.
A. y = 1/5x
B. y = x
C. y = 15x
D. y = 5x
Answer:
D
Step-by-step explanation:
When x = 1, y = 5
When x = 3, y = 15
So, using this, find the slope.
(15 - 5) / (3 - 1) = 10 / 2 = 5
For every x, y increases by 5.
So, y = 5x, or D
Answer:
D

Write
1 quadratic function in
vertex form whose graph
has
the vertex (1,2) and passes
through the point (3,10)
Answer:
y = 2 ( x − 1 ) ^ 2 + 2
Step-by-step explanation:
y = a ( x − h ) ^ 2 + k
where vertex is (h,k) = (1,2)
h=1, k=2
y = a ( x − 1 ) ^ 2 + 2
sub ( 3,10)
10 = a (3 - 1)^2 + 2
a=2
y = 2 ( x − 1 ) ^ 2 + 2
A function is a relationship between inputs where each input is related to exactly one output.
The quadratic function in vertex form is given by:
y = a(x - h)² + k
(h, k) = vertex
The quadratic function in vertex form is y = 2(x - 1)² + 2.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = x + 2 is a function.
We have,
Quadratic function in vertex form whose graph has the vertex (1,2) and passes through the point (3,10).
The quadratic function in vertex form is given by:
y = a(x - h)² + k
(h, k) = vertex
Now,
(h, k) = (1, 2)
Passes through (3, 10).
So,
10 = a(3 - 1)² + 2
10 = 4a + 2
8 = 4a
a = 2
Now,
The quadratic function in vertex form is y = 2(x - 1)² + 2
Thus,
The quadratic function in vertex form is y = 2(x - 1)² + 2.

Your friend says that enough information is given to prove that x= 15. Is your friend correct?
please help
Answer:
Yes, it appears so.
Step-by-step explanation:
Based on the fact that angle L and angle P are congruent, the angles at point M are also congruent to their opposites. All of this points to triangles MNP and MLK being the same, which would mean that x does equal 15. Sorry I couldn't state any specific laws or anything.

Ed bus a box of eggs costing £2.30, two packs of bacon for £2.60 each and two tins of baked beans. He pays with a £10 note gets 80p change how much did the tin of beans cost?
Answer:
£0.85 for each
£1.70 for both
Step-by-step explanation:
Variable x = cost of baked beans
2.30 + 2(2.60) + 2x = 10 - 0.80
Use PEMDAS
2.30 + 5.20 + 2x = 10 - 0.80
7.50 + 2x = 9.20
Subtract both sides by 7.50
2x = 1.70
Divide both sides by 2 to isolate the variable
x = 0.85
Let's check our work by plugging this into our original equation
2.30 + 2(2.60) + 2(0.85) = 10 - 0.80
2.30 + 5.20 + 1.70 = 10 - 0.80
7.50 + 1.70 = 9.20
9.20 = 9.20
Our number is correct

Step-by-step explanation:
Given

Find x
Using law of sine, we have:
[tex]\frac{a}{sin A} = \frac{b}{Sin B}[/tex]
So, we have:
[tex]\frac{x}{sin 32} = \frac{18}{Sin 100}[/tex]
Make x the subject
[tex]x = \frac{18 * sin 32}{Sin 100}[/tex]
[tex]x = \frac{18 * 0.5299}{0.9848}[/tex]
[tex]x = 9.685[/tex]

Q1: A number minus 4 is greater than 2 times a number
Answer:
x - 4 > 2x
(see below to solve for x if needed)
Step-by-step explanation:
"Greater than" is key word for the greater than symbol: >.
"A number" can be represented by x.
So "a number minus four" would be x - 4 and "two times a number" would be 2x.
So "A number minus 4 is greater than 2 times a number" is:
x - 4 > 2x
If you were to solve for x, it would be:
x - 4 > 2x
-x -x
-------------
-4 > x
x < -4

somebody help please
Answer:
The last one
Step-by-step explanation:
The fast reason why - all the other scenarios require 3 lines: 2 lines both parallel to a 3rd, or 2 lines cut by a transversal line, etc. The diagram only shows 2 lines. So the right answer must be the one that doesn't require a third line to be present. :)
The longer answer why - See how angles 2 & 3 have the same style of arc? That is telling you they are of equal measure. So together they are a straight angle, 180°. And they are equal to each other, so 2x = 180° --> each one must be a 90° angle.
Wherever two lines cross, if one angle is a right angle, all 4 angles at the intersection also must be right angles, so everything is perpendicular.
Functions f(x) and g(x) are shown:
f(x) = x2 g(x) = x2 + 8x + 16
In which direction and by how many units should f(x) be shifted to match g(x)?
A. Left by 4 units
B. Right by 4 units
C. Left by 8 units
D. Right by 8 units
Answer:
Step-by-step explanation:
Factor g(x)
(x+4)(x+4)
(x+4)^2
So f(x) needs to be shifted left by 4 units.
Answer:
Option A, Left by 4 units
Step-by-step explanation:
Step 1: Convert g(x) to a function square
We currently have g(x) in this order: [tex]ax^2 + bx + c[/tex]
However, we want g(x) to be in this order: [tex](ax + c)^{2}[/tex]
The first thing we have to do is to factor it out:
[tex]g(x)=x^{2}+8x+16[/tex]
[tex]g(x) = (x + 4)(x + 4)[/tex]
[tex]g(x) = (x+4)^{2}[/tex]
Step 2: Now we can see which way we need to move it
The original form is: [tex]f(x) = (ax - b)^{2}[/tex]
Since the - has changed to a +, that means that we moved -4 spaces down the x-axis. This means that we move left by 4 units.
Answer: Option A, Left by 4 units
