Answer:
315 miles
Step-by-step explanation:
y = distance
x = time
y = 45x
y = 45(7)
y = 315
You can find the rate by y/x
22.5/.5 = 45
67.5/1.5 = 45

Answer:
y + 2= [tex]\frac{2}{3}[/tex]x - 2 [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Adding 2 to y is equivalent to [tex]\frac{2}{3}[/tex](x-4). To simplify, we can do
y + 2= ([tex]\frac{2}{3}[/tex])x - ([tex]\frac{2}{3}[/tex])4
(2/3 × x= [tex]\frac{2}{3}[/tex]x) - ([tex]\frac{2}{3}[/tex] × 4= 2 [tex]\frac{2}{3}[/tex])
y + 2= [tex]\frac{2}{3}[/tex]x - 2 [tex]\frac{2}{3}[/tex]
how can you find the simplest form of 100/1,000?
Answer:
0.1
Step-by-step explanation:
To figure this out, since the numbers are pretty much the same with a 1 and 0's, we can take the 100 and subtract the number of zeros in 1,000, which is 3. So, take the decimal point which is by the last 0 on the 100 and move it 3 times because there are 3 zeros in 1,000:
100.0 (This is where the decimal would be in one hundred)
10.0 (This is one decimal point over)
1.0 (This is two decimal points over)
0.1 (This is three decimal points over)

Answer:
y = -0.4x + 12.6
Step-by-step explanation:
Given the following functions, find the indicated values.
f(x)=1-2x
a. f(-2)
b. f(0)
c. f(2)
Answer: {5, 1, 3}
Step-by-step explanation:
Plug in the numbers in parentheses for x.
a: f(-2) = 1-2(-2) = 1+4 = 5
b: f(0) = 1-2(0) = 1-0 = 1
c: f(2) = 1-2(2) = 1-4 = -3
Answer: 5, 1, -3
Step-by-step explanation:
1. f(-2) = 1-2x(-2) = 1+4 =5 ; f(-2)= 5
2. f(0) = 1-2(0) = 1-0 = 1 ; f(0) = 1
3. f(2) = 1-2(2) = 1-4 = -3 ; f(2) = -3
At track practice, Alexia ran 5 attempts of the 100-meter dash. All of her times were different values between 11 and 13 seconds, except for an attempt when she tripped and finished in 24 seconds.
Alexia's coach said they would remove the 24 result from the set of these practice times.
How will removing this time affect the mean and median?
(Choice A)
A
Both the mean and median will decrease, but the mean will decrease by more than the median.
(Choice B)
B
Both the mean and median will decrease, but the median will decrease by more than the mean.
(Choice C)
C
Both the mean and median will increase, but the mean will increase by more than the median.
(Choice D)
D
Both the mean and median will increase, but the median will increase by more than the mean.
Answer:
A is correct
Step-by-step explanation:
khan
Removing this time affects the mean and the median will decrease but the median will decrease by more than the mean.
Option B is the correct answer.
What is median?It is the middles value of the given set of numbers after arranging the given set of numbers in an order.
We have,
The value 24 is an outlier, and its removal will have a greater effect on the mean than on the median.
Since all of Alexia's other times are between 11 and 13 seconds, removing the 24 will bring the mean closer to the values between 11 and 13.
However, the median, which is the middle value of the ordered set, will not change as much, since it is not affected by extreme values like the outlier.
Therefore,
Both the mean and median will decrease, but the median will decrease by more than the mean.

Answer: 50 inches would represent the scale drawing as 250 feet
Step-by-step explanation:
im not exactly sure what your asking but there brainliest if im right?
Answer:
The length of the building in the scale drawing is 31. 25 Inches
Step-by-step explanation:
Scale drawing was used0. 25 inches represents 2 feetThe length of the building is 250 feetThen,
If 0. 25 inches = 2 feet
Then x inches = 250 feet
cross multiply
x × 2 = 0. 25 × 2500
Multiply through, we then have
2x = 62. 5
Make 'x' the subject by dividing both sides by 2
2x/2 = 62. 5/ 2
x = 31. 25 Inches
Tom has 2 boards that are the same length as Bill's. He says that he found the total length of the boards by adding 28 twelfths and 23 twelfths. Does his method work? Explain.
Answer:This method does not work
Step-by-step explanation:
Since the 2 boards have the same length, the addition of the 2 boards should be the same.
Since 28 does not equal to 23, the method will not work.

Which of the following elevations is less than negative -5 feet from sea level?
A)negative -10 feet
B)negative-3 feet
C) positive 2
D) positive 5 feet
Solution:
An elevation of -10 ft would be less than -5 ft from sea level.
(NOTE) When it comes to negative integers on a number line, just keep in mind that the closer to 0 the negative integer is, the greater in value it becomes. However, the further away from the zero mark the integer is, the value decreases/is a smaller number.
This being said, lets look at the given options.
A) -10 feet ← Notice when you place -10 on the number line, the point is far to the left of the zero mark, as well as -5. This being said, this most likely means that this is a lesser elevation level than that of -5 feet from sea level.B) -3 feet ← Notice when you place -3 on the number line, the point is also to the left of the zero mark, however it is ahead of -5. This being said, this elevation is not lesser than -5 feet from sea level, and hence not the correct choice.C) 2 feet ← Notice when you place 2 on the number line, the point is just to the right of the zero mark and is definitely ahead of -5 feet. This means that this elevation is not lesser than -5 feet from sea level, and hence is not the correct choice.D) 5 feet ← Notice that when you place 5 on the number line, the point is to the right of the zero mark and is definitely also ahead of -5 feet. This being said, this means that this elevation is not lesser than -5 feet from sea level, and hence is not the correct choice.Hence, in conclusion to all of this, our correct choice would be A) -10 feet, considering it is the only elevation that is less than -5 feet from sea level.

The value 5^6 is 25 . 25 . 25 = 15,625
Step-by-step explanation:
For 5^6, we can multiply 5 for 6 times as per stated on the question
5^6 = 5 x 5 x 5 x 5 x 5 x 5
Then we can simplify that value by pairing 2 items of 5
5^6 = (5 x 5) (5 x 5) (5 x 5)
And makes one of the easiest multiply number (5x5) equal 25
So 5^6 = 25 x 25 x 25
= 15,625

PLS HELP 25 POINTS! DUE TODAY
Answer:
Simplifying
5x + 3 = 2x + 1
Reorder the terms:
3 + 5x = 2x + 1
Reorder the terms:
3 + 5x = 1 + 2x
Solving
3 + 5x = 1 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
3 + 5x + -2x = 1 + 2x + -2x
Combine like terms: 5x + -2x = 3x
3 + 3x = 1 + 2x + -2x
Combine like terms: 2x + -2x = 0
3 + 3x = 1 + 0
3 + 3x = 1
Add '-3' to each side of the equation.
3 + -3 + 3x = 1 + -3
Combine like terms: 3 + -3 = 0
0 + 3x = 1 + -3
3x = 1 + -3
Combine like terms: 1 + -3 = -2
3x = -2
Divide each side by '3'.
x = -0.6666666667
Simplifying
x = -0.6666666667
