What does the variable r represent in the equation 10r+4=8?
what does r represent in it?????
URGENTTTT
Answers
I think “represent” is asking you to solve to a number.
10r + 4 = 8
Subtract 4 from both sides of the equation:
10r = 4
Divide both sides by 10:
r = 0.4
Check the math:
10(0.4) + 4 =

Volume= 360 feet³
Step-by-step explanation:
We have two shapes, a triangular prism and a rectangular prism.
Rectangular Prism: [tex]w=6, h=2, l=8, V=lwh[/tex]
So, the volume is 6×2×8=96 feet³
Triangular Prism: [tex]h=5.5-2=3.5, w=6, l=8, V=\frac{1}{2}lwh[/tex]
So, the volume is (5.5×6)÷2 ×8= 33×8=264 feet³
We have to combine the two volumes to find the volume of the whole shape. 96+264=360. So, the volume of the whole shape is 360 feet³

This may be wrong, but x = 10
Explanation:

Ed stands on a moving walkway and gets from one end of the walkway to the other in 20 seconds. The walkway is 44 feet long. Which statements are true?
Every 8 seconds, Ed travels 32 feet.
Ed travels 11 feet every 5 seconds.
Ed travels 2.2 feet per second.
Ed travels 0.9 of a foot every 2 seconds.
Every 10 seconds, Ed travels 22 feet.
Answers
Ed travels 2.2 feet per second.
Every 10 seconds, Ed travels 22 feet.
Ed travels 11 feet every 5 seconds.
Explanation:
Divid feet (44) by the seconds (20) to find out how far Ed can move in a second.
44 ÷ 20 = 2.2
Multiply the feet per second by the seconds in each option to see which is correct.
(I’ll go through them in order of how you listed them)
8 x 2.2 = 17,6 So first one is false
5 x 2.2 = 11 So it’s true
1 x 2.2 = 2.2 So it’s true
2 x 2.2 = 4.4 So it’s false
10 x 2.2 = 22 So it’s true
(Now you know how to do it!) :D

Juan's earnings vary directly with the number of hours he works. Suppose that he worked 10 hours yesterday and earned $160. How much will he earn today if he works 13 hours?
Answers
Explanation: Find the unit rate/how much he earns if he works 1 hour
160 divided by 10: 16
Which will mean: 16 dollars for working 1 hour.
Multiply 16 by 13 to find out how many he earns for working 13 hours
16 x 13 = 208
So Juan earns $208 if he works 13 hours

X2-12x+21=-6 solve the quadratic by factoring
Answers
Answer:
(x-3)(x-9)
Step-by-step explanation:
first thing you need to do is move the -6 over. so we're going to add 6 to both sides (we add because it's negative 6 and we need 0 on the right side)
so you have: x^2-12x+27
now we need to come up with two numbers that add to -12 and multiply to 27.
the factors of 27 are 9 & 3 and 27 & 1. only 9 & 3 add to 12 so we are going to use those.
since the 12 is negative however, 9 and 3 should both be negative.
therefore we get: (x-3)(x-9)

Green = 9
Yellow = 6
A. 3/5
B. 11/15
C. 2/5
D. 4/15
Answers
Answer:
Probability(Not red) = 11 / 15
Step-by-step explanation:
Given:
Outcomes;
Red = 8
Blue = 7
Green = 9
Yellow = 6
Find:
Probability(Not red)
Computation:
Probability(Not red) = 1 - Probability(red)
Probability(Not red) = 1 - [Number of red/ Total]
Probability(Not red) = 1 - [8/(8+7+9+6)]
Probability(Not red) = 1 - [8/30]
Probability(Not red) = 1 - [4/15]
By taking LCM
Probability(Not red) = (15 - 4) / 15
Probability(Not red) = 11 / 15

Both C and D can be correct. But the answer would be D. Here is why
Intersecting lines are two or more lines that cross. Yes these lines are crossing by perpendicular lines also cross. The difference is, intersecting lines can cross at any angle. Perpendicular lines have to cross at 90 degrees making 4 right corners.

Suppose that the population of deer in a state is 7,700 and is growing 3% cach year. Predict the population
after 5 years
Answers
Answer:
Future Value= 8,927
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 7,700
Growth rate (g)= 3%
Number of periods (n)= 5 years
To calculate the future value (FV) of the population after 5 years, we need to use the following formula:
FV= PV*(1 + g)^n
FV= 7,700*(1.03^5)
FV= 8,927

(-1, -2), 3x - y = 5
Answers
3x - y = 5
3x = y + 5
y = 3x - 5
Parallel = same slope
Slope = 3
Y = 3x + b
Plug in the point
-2 = 3(-1) + b
-2 = -3 + b, b = 1
Solution: y = 3x + 1
Answer:
y = 3x + 1
Step-by-step explanation:
the slope of the line of the given equation can bé find in this way: -a/b, where a is the number that multiplies x and b is the number that multiplies y
m = -3/-1 = 3
two parallel lines have the same slope, so also the line that we are a searching has m=3
now we can use this formula
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point
y-(-2) = 3 (x-(-1)
y+2 = 3x + 3
y = 3x + 3-2
y = 3x + 1
