There are 205 total students in a school. 20% of the students are 5th
graders. How many students are 5th graders? *
Answer:
41 students
Step-by-step explanation:
We're trying to find what 20% of 205 is so:
We start by converting 20% to a fraction :
20% = 1/5
Then we have
20% of 205 = 1/5 x 205 = 1/5 x 205/1 = 205/5
Notice that 205 was rewritten as the fraction 205/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.
In order to find the simplest form of 205/5 we cancel out the greatest common divisor of 205 and 5, which is 5:
205/5 = 41/1
So there are 41 5th graders
f(x) = 2x2 + 12x + 1
Determine the vertex
Answer:
Step-by-step explanation:
The vertex would be the highest/lowest point so lets factor this first
when we factor we get
2(x^2+6x+8)
2(x+4) (x+2)
Using zero product property we find the 2 x values and x intercepts are
-4 and -2
the middle point of these points is -3
Substitute -3 for x and solve
2(-3+4) (-3+2)
2 * 1 * -1
2*-1
-2
(-3,-2) is the vertex

Step-by-step explanation:
At the beginning of a snowstorm, Nathaniel had 5 inches of snow on his lawn.
The snow then began to fall at a constant rate of 1.5 inches per hour.
Assuming no snow was melting, how much snow would Nathaniel have on his
lawn 5 hours after the snow began to fall? How much snow would Nathaniel
have on his lawn after t hours of snow falling?
Snow after 5 hours:
Show after t hours:
Answer:
In 5 hours he would have 7.5 inches of snow JUST from the snowstorm but the question says that he already had 5 inches in his lawn so that would make 12.5 inches of snow in 5 hours.
The second one says t, it doesn't state a number so lets assume the number is ten. So that's 5 more hours of constant snowfall, this makes our total be the sum of 12.5+7.5. This is equal to 20.
10 hours into the snowstorm Nathaniel had 20 inches of snow in his lawn.
Consider a brainliest if it helps :)
Answer:
Snow after 5 hours = 12.5
Show after t hours= 1.5t+5

Answer:
y = -|x -1| +2
Step-by-step explanation:
The transformation ...
-f(x -h) +k
reflects function f(x) over the x-axis, translates it 'h' units to the right and 'k' units up.
Your absolute value function is reflected over the x-axis, then translated 1 unit right (h=1) and 2 units up (k=2). Putting these values in the function, we have ...
y = -abs(x -1) +2
y = -|x -1| +2

Step-by-step explanation:
In 2019, there were about 21 million teenagers (aged 13-17) in the United States. They each sent an average of 3,300 text message per month. About how many text messages did all of the teenagers in the United States send each month? Express your answer using scientific notation.
Answer:
All of the teenagers in the United States sent about 69,300,000,000 text messages each month.
Step-by-step explanation:
Given that in 2019, there were about 21 million teenagers in the United States, and they each sent an average of 3,300 text messages per month, to determine about how many text messages did all of the teenagers in the United States send each month the following calculation should be done:
21,000,000 x 3,300 = X
69,300,000,000 = X
Therefore, all of the teenagers in the United States sent about 69,300,000,000 text messages each month.

Answer:
1. B.
2. A, E.
3. D.
Step-by-step explanation:
1. 8.225 ÷ 5 = 1.645
2. 892 ÷ 8 = 111.5
8920 ÷ 80 = 111.5
894 ÷ 10 = 89.4
89.2 ÷ 0.08 = 1115
8.92 ÷ 0.8 = 11.15
0.892 ÷ 0.008 = 111.5

Find the solution to the system of equations. Please Help
Answer:
x=−2
y=−4
Step-by-step explanation:
−2x+2y=−4
3x+3y=−18
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
−2x+2y=−4,3x+3y=−18
To make −2x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by −2.
3(−2)x+3×2y=3(−4),−2×3x−2×3y=−2(−18)
Simplify.
−6x+6y=−12,−6x−6y=36
Subtract −6x−6y=36 from −6x+6y=−12 by subtracting like terms on each side of the equal sign.
−6x+6x+6y+6y=−12−36
Add −6x to 6x. Terms −6x and 6x cancel out, leaving an equation with only one variable that can be solved.
6y+6y=−12−36
Add 6y to 6y.
12y=−12−36
Add −12 to −36.
12y=−48
Divide both sides by 12.
y=−4
Substitute −4 for y in 3x+3y=−18. Because the resulting equation contains only one variable, you can solve for x directly.
3x+3(−4)=−18
Multiply 3 times −4.
3x−12=−18
Add 12 to both sides of the equation.
3x=−6
Divide both sides by 3.
x=−2
The system is now solved.
x=−2,y=−4

6. You buy a pair of shoes that cost $120. You use your 20% off coupon and pay an 9% tax. What is your
total bill?
Answer:
$104.64
Step-by-step explanation:
Because coupons come before tax, we have to take away 20%, then add 9%
Step 1 : Find 20%
In order to find the percent of anything, all you have to do is multiply the percent (as a decimal) by your price
In this case, it's : 120 × 0.20
Using this expression, we find that 20% of $120 = $24
Step 2 : take away 20%
Coupons take away money from a full price, so we will take away $24 from $120, leaving us with $96
Step 3 : Find 9%
Now we multiply 0.09 (9%) by our new price (96)
96 × 0.09 = $8.64
Step 4 : Add 9%
Lastly, we use our coupon-added price (96) and add our tax (8.64)
96 + 8.64 = $104.64

please factor -28c-12c²-16
Answer:
-4(3c + 4)(c + 1)
Step-by-step explanation:
Reorder the expression
-12c² - 28c - 16
Divide it by -4
3c² + 7c + 4
Factor it by multiplying a (3) and c (4), then finding 2 factors that add up to b (7)
Two factors of 12 that add up to 7 are 4 and 3.
Use 4c and 3c to substitute for 7c in the expression, and simplify
3c² + 7c + 4
3c² + 3c + 4c + 4
3c(c + 1) + 4(c + 1)
(3c + 4)(c + 1)
Since we factored out a -4 in the beginning, add this in front
-4(3c + 4)(c + 1)

Answer: I would find it by counting the squares so that you can get 2 numbers and then do the formula for the area of a parallelogram. For the sides to find the number, you might want to draw a square around the parallelogram so that you get a triangle and then use the Pythagorean theorem to find the side of the parallelogram.

x
where
k
is some constant.
We are given that
