Answer:
3; Sara is driving 30 miles per hour
Step-by-step explanation:
Here in this question, we want to select which of the options represent what a unit rate is.
When we talk of rate, we are referring to how a particular measured entity is changing in relation to another measured entity. Hence, we are simply looking at how there is a change between two measurable quantities.
Option 1 is not rate, it only tells us Sara ate 1 cookie. How Sara did this, we do not know, whether fast or slow
Option 2 is just measuring distance. We only know that Sara traveled a particular distance. We do not know how fast, or slow this has occurred
Option 3 is our answer. It clearly tells us how the distance Sara is traveling is measured against time
Option 4 is not correct, we only know the number of crackers and apples are, the rate at which this is done, we do not know
Leslie ran a total of 8 miles over the course of 4 track practices. How many miles would Leslie have ran after 5 track practices? Solve using unit rate.
Answer:
10 miles
Step-by-step explanation:
Find how much she runs during one track practice by dividing 8 by 4. This gives you the equation 2x, with x being the number of track practices.
Answer: 10 miles after 5 track practices.
Step-by-step explanation: Lets find the unit rate of this problem. Remember that unit rate means the denominator will always have a 1.
8/4 converted to a unit rate is 2/1
The unit rate is 2 miles per every 1 track practice.
We can use the unit rate to solve how many miles Leslie would have ran after 5 track practices.
2/1 x 5 = 10/5
So, Leslie would have ran 10 miles after 5 track practices.

Which two numbers of the given data set have the same absolute value? Explain your answer in full sentences.
-5, 5, -3, 8
pls help. ;)
Answer:
The answer is -5 and 5 because when you do absolute value if there is a negative number then it turns into a positive number. Negatives will always turn out as positives when doing absolute value. :)
Step-by-step explanation:
Answer: the two numbers that have the same absolute value is -5, and 5.
Step-by-step explanation:
Absolute will just make any negatives to positive.
So, the absolute value of -5 is 5, or the absolute value of -3, is 3.
If it's already positive, then nothing happens; it stays the same
So, the absolute value of 8 is 8, nothing is changed.
Discuss the continuity of the function (tan^-1 x)/x at x= 0
Step-by-step explanation:
This graph has a vertical asymptote at x=0, this means that it is not continues at x=0. However as the Limit, x approches 0, it is very close to 57.296.
x + 3y = 25
2x + y = 15
Answer: x=4 and y=7
Step-by-step explanation: x+3y=25
x+3y+−3y=25+−3y(Add -3y to both sides)
x=−3y+25

Answer:
5(x+8)-1=20+2(x+8)
or, 5x + 40 -1 = 20 + 2x + 16
or, 5x-2x = 20+ 16 -39
3x = -3
x = -1

the price of gravel is $24 for every 3/8 ton. kate wants to know the price of 2 tons of gravel
Answer:
$128
Step-by-step explanation:
your looking for 16/8, divide 16 by 3, leaving you with 5.333...
now times that by $24, and you have your answer hope this helps
The price of 2 tons of gravel is $128.
Given:
The price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.
To find:
The price of 2 tons of gravel.
Explanation:
Let [tex]x[/tex] be the price of 1 ton of gravel.
Then the price of [tex]\dfrac{3}{8}[/tex] ton is [tex]\dfrac{3}{8}x[/tex] and the price of 2 tons of gravel is [tex]2x[/tex].
It is given that the price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.
[tex]\dfrac{3}{8}x=24[/tex]
[tex]x=\dfrac{8}{3}\times 24[/tex]
[tex]x=8\times 8[/tex]
[tex]x=64[/tex]
Now, the price of 2 tons of gravel is:
[tex]2x=2(64)[/tex]
[tex]2x=128[/tex]
Therefore, the price of 2 tons of gravel is $128.

what coordinate expression represents the coordinates of any point after dilation by any scale factor, a?
Answer:
(x,y) → (ax,ay) .
Step-by-step explanation:
A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.
If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).
So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of a:
(x,y) → (ax,ay) .
Answer:
[tex]\huge\boxed{(ax, ay)}[/tex]
Step-by-step explanation:
In order to dilate the coordinates of a point, we want to make it [tex]a[/tex] times bigger. In order to do this, we can multiply the x and y values by our scale factor, a. This is called mapping. What it does is it basically multiplied our points by a specific number so that we end up with a figure that is [tex]a[/tex] (the scale factor) times bigger than the original.
So in order to make an expression for this, we multiply the x and y coordinates by a. So we have ax and ay.

Jason has applied to be a camp counselor for the summer. The job pays $9 per hour. The equation to re
job is y = 9x, where x is the number of hours he works and y is the total amount he earns,
Mia has applied to be a lifeguard for the summer. The lifeguard job is three days a week with hours and
the table below.
Hours worked
Amount paid
Tuesday
6
$52.50
Thursday
8
$70,00
Saturday
5
$43.75
Which statement best describes the hourly rates?
O The two jobs pay the same hourly rate.
The comparison cannot be made with the information given.
O Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Jason's camp counselor job pays a lower hourly rate than Mia's lifeguard job.
Answer:
The correct statement is (3).
Step-by-step explanation:
Jason's hourly pay rate as a camp counselor for the summer is:
J = $9 / hour.
The table representing Mia's pay as a lifeguard for the summer is as follows:
Days Hours worked Amount paid
Tuesday 6 $52.50
Thursday 8 $70,00
Saturday 5 $43.75
Compute Mia's hourly rate for Tuesday: [tex]\frac{\$52.50}{6}=\$8.75[/tex]
Compute Mia's hourly rate for Thursday : [tex]\frac{\$70.00}{8}=\$8.75[/tex]
Compute Mia's hourly rate for Saturday: [tex]\frac{\$43.75}{5}=\$8.75[/tex]
Thus, Mia's hourly rate as a lifeguard for the summer is,
M = $8.75 / hour
This implies that Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Thus, the correct statement is (3).
Answer:
The answer is C because if u multiply 6 by 9 its 54 that's how much Jason gets for 6 hours while on the other hand Mia for six hours gets 52 dollars.

Rewrite (x – 3) (x + 5) + (x – 3) (2x – 1) as the product of two binomials.
(x - 3)(x + 5) + (x - 3)(2x - 1)
We can factor out (x - 3) since both terms have that in common. Then we simply add together x + 5 and 2x - 1
(x - 3)(3x + 4) is the final answer.

What is the solution to -3m = -15
Answer:
[tex]m=5[/tex]
Step-by-step explanation:
[tex]-3m=-15[/tex]
Divide both sides by -3:
[tex]\frac{-3m}{-3}=\frac{-15}{-3}[/tex]
[tex]m=5[/tex]
Answer:
[tex]m = 5[/tex]
Step-by-step explanation:
Solve for [tex]m[/tex] :
[tex]-3m = -15[/tex]
-Take [tex]-3m[/tex] and divide it on both sides of the equation:
[tex]\frac{-3m}{-3} = \frac{-15}{-3}[/tex]
[tex]m = 5[/tex]
Therefore, the value of [tex]m[/tex] is [tex]5[/tex].
