Answer:
60%
Step-by-step explanation:
12 kids played. 8 didn't play. That means there is a total of 20 students.
The fraction would be 12/20.
To make it into a percent, divide 100 by the denominator (20) and multiply it by the numerator (12)
100 divided by 20 is 5
12 x 5 = 60
Answer:
60%
Step-by-step explanation:
theres 20 kids and 12 played so yeah its pretty simple
A lost turtle - swimming 13 feet below the surface of the water - begins to ascend at 0.5 foot per second. In hopes of (harmlessly) capturing the turtle, a diver jumps into the water to a depth of 4 feet before descending at a rate of 0.25 foot per second.
a) Write an equation to model the position of the turtle at any given time.
b) Write an equation to model the position of the diver at any given time.
c) After how long will the diver be able to catch the turtle?
d) At what depth will the diver be able to catch the turtle?
9514 1404 393
Answer:
a) T(t) = -13 +0.5t
b) D(t) = -4 -0.25t
c) 12 seconds
d) 7 feet
Step-by-step explanation:
a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...
T(t) = -13 +0.5t
__
b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...
D(t) = -4 -0.25t
__
c) The diver and turtle will be at the same depth when ...
T(t) = D(t)
-13 +0.50t = -4 -0.25t
0.75t = 9 . . . . . . . . . . . . add 13+0.25t
t = 12 . . . . . . . . . . . . . . . divide by 0.75
The diver and turtle will be at the same depth after 12 seconds.
__
d) That depth will be ...
T(12) = -13 +0.5(12) = -13 +6 = -7
The diver and turtle meet at a depth of 7 feet.

Mrs. Garcia’s students were asked to find 220% of 75. Each of the students had a different method.
Amy: “I multiplied 2.20 by 75 to find my answer.”
Braden: “I created a table with columns for 100%, 100%, 20%, and 220%. Then I filled in the table and added the values.”
Colton: “I created a table with columns for 100%, 10%, 10%, and 220%. Then I filled in
the table and added the values.”
Danielle: “I divided 75 by 5 to find 20%. Then I added 75 twice to what I found to get my final answer.”
If all of the students completed their steps accurately, which student got the answer wrong?
Answer:
Colten took test reveiw on edge!
Step-by-step explanation:
Colton got the wrong answer
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Garcia’s students were asked to find 220% of 75, we need to find who did incorrect answer among Amy, Braden, Colton and Danielle
Amy multiplied 2.20 by 75 to find my answer.”
220/100×75=2.2
His answer is correct
Barden
Braden created table for 100, 100 and 20% and added. This will be equivalent to finding 220%
Braden is correct.
Colton created table for 100%, 10% and 10% percent and added these.
But this addition would result in 100+10+10 =120% not 220%
Hence Colton is wrong.
Danielle divided 75 by 5 to find 20%.
Then he added 75 twice to find his answer.
Danielle is correct.
Hence Colton got the wrong answer

What is the equation of the line in slope -intercept form? *
A. y= x +8
B. y= x - 8
C. y = 8x +8
D. y = 8x - 8
Answer:
d
Step-by-step explanation:
The equation of the line in slope -intercept form is y=x-8, Option b is correct.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
From the graph let us take two points of line joining which are (8, 0) and (0, -8).
m=-8-0/0-8=1
So slope of line is 1.
Now let us find find the y intercept
0=1(8)+b
0-8=b
b=-8
Slope intercept form of line is y=x-8
Hence, the equation of the line in slope -intercept form is y=x-8, Option b is correct.

Mrs. Taylor is knitting socks. it takes her 1/4 hour to knit one pair of socks. She has a meeting to go to in 3 1/2 hours.
How many pairs of socks can she knit before her meeting?
Answer:
14 socks.
Step-by-step explanation:
3 1/2 / 1/4
= 7/2 / 1/4
= 7/2 * 4
= 28/2
= 14 socks.
Answer:
14
Step-by-step explanation:
Mrs. taylor can knit 4 socks in an hour, so if she has to go to her meeting in 3 1/2 hours, she should be able to knit 14 pairs of socks. The reason for this is in 3 hours she can knit 12 socks because 4 times 3 is 12. Then, in half an hour she can knit 2 socks because she can knit one pair in 1/4 so in 1/2 it would be 2.

Take a look at the first graph. Notice it goes through (0,-2) and the slope is 5/2 so the answer is A.Next to find the equation we look at the y-intercept and determine that its -2 and the slope is -5/2. Hence the answer is CStep-by-step explanation:
Problem 1.
Start at (0, -2). Go up 5 and right 2. That is a slope of 5/2.
First choice.
Problem 2.
The y-intercept is (0, -2), so b = -2.
Start at (0, -2). Go down 5 and right 2. That is a slope of -5/2.

The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.
Write an expression to model this situation.
How far could you travel if you drove 40 miles?
Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)
Step-by-step explanation:
The equation for these types of problems is y = mx + b.
M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.
Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.
If you plug everything in, you would get y= $0.20x + $35.
I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.
Now that we know x would be the amount of miles, we can plug that into the equation.
You would get y= $0.20 * 40 + $35.

Cassie wants to buy a pair of shoes for $26.50 and a shirt for $9.50. If the sales tax rate is 8.25%, what will be the amount of sales tax on Cassie’s purchase?
$3.13
$2.97
$3.06
$2.89
The amount of sales tax is $2.97.
The tax for the shoes: 26.50*0.0825=2.18625
The tax for the shirt: 9.5*0.0825=0.78375
2.18625+0.78375=2.97
pls mark brainliest:))
Answer:
B. 2.97
Step-by-step explanation:
First, add 26.5 plus 9.5 to get the total of the purchase without tax. Then, create a proportion (8.25/100= x/36). multiply 8.25 by 36, and divide the product by 100 to get 2.97. Hope this helps!
