Answer:
5
Step-by-step explanation:
For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.
5x -2y= 30
When x=8,
5(8) -2y= 30
40 -2y= 30
40 -30= 2y (bring constant to 1 side)
2y= 10 (simplify)
y= 10 ÷2
y=5
Thus the missing value is 5.
What is the value of hin the figure below? In this diagram, ABAD ~ ACBD.
A. 5
B. 80
c. 16/5
D. 80
E. 16
F. 8
Answer:
F. 8
Step-by-step explanation:
The ratio of the long side to the short side is the same in similar triangles. The long side of triangle BAD is AD, which has length 20-4 = 16.
BD/DE = AD/BD
h/4 = 16/h
h^2 = 64 . . . . . . . multiply by 4h
h = 8 . . . . . . . . . . take the square root (matches selection F)
_____
Comment on this geometry
BD = √(AD·DC) is called the "geometric mean" of the segments AD and DC. This geometry has some other geometric mean relationships as well:
BC = √(AC·DC)
BA = √(AC·AD)

Use the graph to estimate x when y = 0.
You can use this table too. (y = 4x - 5)
｡☆✼★ ━━━━━━━━━━━━━━ ☾
You could just use the equation to get an answer
Substitute y in as 0
0 = 4x - 5
+ 5 to both sides
4x = 5
Divide both sides by 4:
x = 5/4 or 1.25
HOWEVER, you were supposed to use the graph.
If you look at where the line meets the x axis, you can see it is around 1.2

Find the surface area
Answer: 952.46
Step-by-step explanation:
Answer:
1,305
Step-by-step explanation:
15 x 15 = 225 divided by 2 = 112.5
5 x 15 = 225 divided by 2 = 112.5
15 x 24 = 360
15 x 24 = 360
15 x 24 = 360
ADD THEM ALL UP
You get 1305

Find the surface area of the sphere. Use 3.14 for pi. Round to the nearest
tenth. (Given diameter is 17)
Answer:
908, it's rounded to the nearest tenths
Step-by-step explanation:
Answer:
Step-by-step explanation:
Diameter = 17 units
Radius r = 17/2 = 8.5 units
Surface area of sphere = 4πr²
= 4 * 3.14 * 8.5 * 8.5
=907.46 square units

somebody help me please What is 10x + 60 = 300 first answer brainiest
Answer:
x=24
Step-by-step explanation:
10x + 60 = 300
10x=300-60
10x=240
x=24
Answer:
[tex] \boxed{x = 24} [/tex]
Step-by-step explanation:
[tex] Solve \: for \: x: \\=> 10x + 60 = 300 \\ \\ Substrate \: 60 \: from \: both \: sides: \\ =>10x + (60 - \boxed{60}) = 300 - \boxed{60} \\ \\ 60 - 60 = 0: \\ =>10x = 300 - 60 \\ \\ 300 - 60 = 240: \\ =>10x = \boxed{240} \\ \\ Divide \: both \: sides \: of \: 10 x = 240 \: by \: 10: \\=> \frac{10x}{10} = \frac{240}{10} \\ \\ \frac{10}{10} = 1: \\=>x = \frac{24\cancel{0}}{1\cancel{0}} \\ \\=> x = 24 [/tex]
Find the equation of the line below. If necessary, use a slash (/) to indicate a
division bar.
Answer: y=[tex]\frac{1}{5}x[/tex]
Step-by-step explanation: Let me know if you need an explanation.
Answer:
As shown in picture, the line passes (0, 0) then it has form of y = ax
This line also passes (5, 1) => 1 = 5a => a = 1/5
=> The equation of this line: y = (1/5)a

The length of a rectangular park is four timesfour times its width. The park is surrounded by a 33-foot-wide path. Let x denote the width of the park. Write a quadratic function to represent the total area of the park and the path.
The quadratic function that represents the total area of the park and the path is _____.
(Simplify your answer. Do not factor.)
Answer:
A(x) = 4x^2 + 330x + 4356
Step-by-step explanation:
width of park: x
length of park: 4x
width + path width = x + 66
length + path width = 4x + 66
area = (x + 66)(4x + 66)
area = 4x^2 + 66x + 264x + 4356
area = 4x^2 + 330x + 4356
A(x) = 4x^2 + 330x + 4356

Three points, Q, R, and S, lie on the same line such that R lies between Q and S. Find QS if RS = 19 and QR = 32
Answer:
QS=51
Step-by-step explanation:
It was given that RS = 19 and QR =32
QS=x
Q-R was measured and found to be 32
R-S was measured and found to be 19
Q-S will be the sum of Q-R and R-S which is 32+19= 51
QS=51

3.) Alex makes $31,992 per year and pays about 15% of his gross monthly income in federal
taxes. He wants to find an apartment to rent. Estimate how much he can afford to pay for
rent each month. Then determine how much money he will have after taxes and rent are
paid.
Answer: 1699.5 dollars
Step-by-step explanation:
If Alex makes $31,992 per year, then his monthly income will be
31992/12 = 2666 dollars
and he pays about 15% of his gross monthly income. That is
15/100 × 2666 = 399.9
The remaining money will be
2666 - 399.9 = 2266.1
He should able to afford 25% of his monthly income for rent
25/100 × 2266.1 = 567 dollars
The money left after tax and payment for rent will be
2266.1 - 567 = 1699.5 dollars
