The equation which shows how to find the height in inches of based on the screen's width is; h=2w
What is the screen's height in terms of the screen's width?According to the taks content!
The ratio of the height of the screen to its width is 18:9.
On this note, it follows that;
h/w = 18/9
By making the h the subject of the formula;
h = 18w/9
h = 2w.

A rectangular prism has a height of 4.5 cm, length of 7.2 cm and a width of 9 cm. Joe is going to cover the sides only. How much paper will he need?
Answer:
210.6cm^2
Step-by-step explanation:
1) In the diagram below the shape of the rectangular prism is shown:
where L=7.2, W= 9 and H=4.5
In order to cover only the sides, the area of the front and back faces and the side faces should be added, the top and bottom faces should not be
so the area of front and back faces= 2 (length *width) (multiply by 2 to account for both the front and back face, instead of just one face)
=2(7.2)(9)= 129.6 cm^2
area of side faces: 2(W)(H)=2*9*4.5=81cm^2
129.6cm^2+81cm^2=210.6 cm^2
How many solutions exist for the given equation? 3(x 10) 6 = 3(x 12) zero one two infinitely many
The given equation 3(x+10)+6=3(x+12) has infinitely many solutions.
We have the following expression
[tex]3(x+10)+6=3(x+12)[/tex]
We must rewrite both sides of the equation.
For this, we use the distributive property.
What is the distributive property?
A (B + C) = AB + AC
We have then
3(x+10)+6=3(x+12)
Adding like terms we have

We observe that we have two equal equations.
Therefore, the equations intersect for any value of x.
Therefore, the equation has infinite solutions.

Answer:
y=2x+4
Step-by-step explanation:
**Your line isn't clearly shown on point with the grid**
If you want this in the slope-intercept form then here it is:
Slope-intercept formula: y=mx+b
Your coordinates: (-3,2) and (1,10)
To find the slope (which is the "m" in the formula) you need to do this formula:
y2 - y1 / x2 - x1 =
(The 2's and 1's should be subscript)
10-2/1-(-3) = 8/4
8/4=2
The slope should be 2
Formula right now: y=2x+b
You need to find the y-intercept:
That should be a point on the y-axis.
(0,n) **N is used for a variable since we don't have a number yet.
In your coordinate plane, (0,4) is your y-intercept.
When writing the y-intercept in the formula don't write a coordinate write the "y"
Formula: y=2x+4

Gene has a gasoline budget of $300 per month. He uses an average of $7 of gasoline each day he drives. Which of the following equations represents how much money is left in his gasoline budget after x days of driving? A. y = 300 + 7x B. y = 7x - 300 C. y = 300x - 7 D. y = 300 - 7x
Answer:
y=300-7x
Step-by-step explanation:
since monthly budget for gasoline=$300
Per day, he uses an average of $7 of gasoline
after x days he will use $7x of gasoline.
remaining amount after x days of driving= 300-7x
the equation will be y= 300-7x

HELP! WILL GIVE BRAINLEST! In a right triangle, sin(β) = 0.292. If the hypotenuse of the triangle has a length of 17.5 cm, what is the length of the side adjacent to angle β. Note: You will also need to use the Pythagorean theorem to answer this question.
16.7 cm
5.1 cm
11.4 cm
4.1 cm
Applying the sine ratio and the Pythagorean theorem, the adjecent length to angle β is: A. 16.7 cm.
What is the Sine Ratio?The sine ratio is given as, sin ∅ = opposite/hypotenuse.
Given the following in a right triangle:
∅ = β sin(β) = 0.292Hypotenuse = 17.5 cmFind the opposite side by applying the sine ratio:
0.292 = opp/17.5
Opposite = (0.292)(17.5)
Opposite = 5.11
Using the Pythagorean theorem, we have:
Adjacent length = √(17.5² - 5.11²)
Adjacent length = 16.7 cm.
Thus, applying the sine ratio and the Pythagorean theorem, the adjecent length to angle β is: A. 16.7 cm.

What is the volume of this solid?
O A. 63
O B. 10
O c. 27
O D. 39
Answer:
Find the cube's volume first (because it's the simplest figure) by using the formula;
(Formula for vol. of cube)
V = [tex]s^{3}[/tex]
Where 's' stands for one side of the cube raised to the power of three.
or
V = w · l · h
Where 'w' stands for the width, 'l' stands for the length, and 'h' stands for the height.
Plug in the values you know since they literally give it to you (I'll be using the formula [tex]s^{3}[/tex]);
V = [tex]s^{3}[/tex]
V = 3^3 → (The symbol ' ^ ' means to the power of.)
V = 27, is the volume of the cube.
Now we find the volume of the pyramid using the formula;
(Formula for vol. of pyramid)
V = (l · w · h) · 1/3
Where 'l' means the length, 'w' the width, and 'h' the height whereas the 1/3 is just dividing the product of those three by 3.
Plug in the values you know using both the lengths from the cube and pyramid.
What we know of the dimensions for the cube:Length = 3
Width = 3
Height = 3(we won't use)
What we know of the dimensions for the pyramid:Height = 4
Use these to figure out the volume for the pyramid.
V = (l · w · h) · 1/3
V = (3 · 3 · 4) · 1/3
V = 36 · 1/3
V = 36/3
V = 12, is the volume of the pyramid.
Add your volumes:-
27(cube vol.) + 12(pyramid vol.)
= 39 is the volume for this whole solid, your answer is D.
Which is the smallest fraction?
A. 1/3
B. 1/6
C. 1/4
D. 1/7
Answer:
its 1/7 because if you have a pizza and you cut it in 3 pieces, it will be bigger than a pizza cut in 4 pieces.
So basically if you buy a pizza and you were originally going to cut it in 3 pieces, but then one of your other friend wants a piece, so now you will have to cut it into 4 pieces which will give you a smaller piece and the same way cutting a pizza into 7 pieces will make it way smaller
so its D
but if you are asking from another point of view than I guess it A
