3 Select the correct answer. The variable y varles directly as x. When x = 20, y= 12. What is the value of y when x= 15?
А. 7 B. 9 C. 18 D. 25
Answer:
B.9
Step-by-step explanation:
What I did is I used ratio.
20:12
15:X
Cross multiply:15x12
Answer:180
The answer you get divided by 20.
180/20=9.
Answer:
B
Step-by-step explanation:
Given y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when x = 20, y = 12, then
12 = 20k ( divide both sides by 20 )
k = [tex]\frac{12}{20}[/tex] = [tex]\frac{3}{5}[/tex]
y = [tex]\frac{3}{5}[/tex] x ← equation of variation
When x = 15, then
y = [tex]\frac{3}{5}[/tex] × 15 = 9

A set of speakers costs $22 and songs cost $1.25 each. The sales tax rate is 7.5%. The expression 0.075(22 + 1.25s) can be used to determine the amount of sales tax due on the entire purchase of a set of speakers and s songs. Expand the expression and round to the nearest hundredth.
Answer:
0.94s+1.65
Step-by-step explanation:
0.075*22+0.075*1.25s
0.075*22 is 1.65
0.075*1.25s is 0.9375 but rounded to the nearest hundreth so 0.94.
Our final expression is 0.94s+1.65

Can the sides of a right triangle have sides the lengths of 48.5ft, 32.5ft, and 30 ft?
Answer:
No, you can't have a right triangle with the sides 48.5ft, 30ft, 32.5ft.
Step-by-step explanation:
48.5 + 30 + 32.5 = 111 ft
Triangle's total sides: 180.
One side has to be equal to 90ft.
Answer:
Step-by-step explanation:
32.5²+30²=1056.25+900=1956.25
48.5²=2352.25≠1956.25
so it is not a right angled triangle.

What does it mean to translate an x and y coordinate into a composition?
Answer: When a point or figure on a coordinate plane is moved by sliding it to the right or left or up or down, the movement is called a translation. The figure is translated from one position to another. Example 1: A point is located at (3, 7) on the coordinate plane. In geometry, a translation is the shifting of a figure from one place to another without rotating, reflecting, or changing its size. This is done by moving the vertices of the figure to the prescribed number of spaces on a coordinate plane and then drawing the new figure. There are four main types of transformations: translation, rotation, reflection, and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.

What is the surface area of the sphere?Let r be the radius of the sphere. Then the surface area of the sphere will be given as,
SA = 4πr² square units
The radius of the sphere is 9 units. Then the surface area of the sphere is calculated as,
SA = 4 x π x 9²
SA = 4 x π x 81
SA = 324π square units
The surface area of the sphere will be 324π square units. Then the correct option is D.

69= 7x + 5x + 9. Please help. I need this done by 12/4/2020
______________________________
1.) Swap sides so that all variable terms are on the left hand side:[tex]7x+5x+9=69[/tex]
- This is an optional step. I prefer the numbers to be on the left hand side, but it's not necessary.
Equation at the end of Step 1:
[tex]7x+5x+9=69[/tex][tex]69=7x+5x+9[/tex]2.) Combine 7x and 5x:[tex]7x+5x=12x[/tex]
- We combine like terms because there is 2 x's, and we need 1 x.
Equation at the end of Step 2:
[tex]12x+9=69[/tex]3.) Subtract 9 from both sides:[tex]9-9=[/tex] Cancels Out[tex]69-9=60[/tex]
- When solving problems like this, to get x alone you have to do the opposite of what you see.
- In this case, we have a positive 9. So to get rid of 9 we do the opposite: -9 on each side.
Equation at the end of Step 3:
[tex]12x=60[/tex]4.) Divide both sides by 12:[tex]12x[/tex] ÷ [tex]12=x[/tex][tex]60[/tex] ÷ [tex]12=5[/tex]- When solving problems like this, to get x alone you have to do the opposite of what you see.
- In this case, we have 12 being multiplied by x. So to get rid of the 12 we do the opposite: Divide by 12 on each side.

When 20 is subtracted from five times a number, the result is the same as when 18 is added to three times the number. What is the number?
Answer:
Number is 19
Step-by-step explanation:
denote the number by x.
the line says:
5x - 20 = 18 + 3 x
Subtracting 3x form both sides
2x - 20 = 18
adding 20 to both sides
2x = 38
dividing both sides by 2
x = 19
Answer:
19
Step-by-step explanation:
let n = the number
5n - 20 = 18 + 3n
combine like terms in one of four different ways
2n = 38
n = 19
