The height of a football after it's been kicked from the top of a hill is h=2(-2-4t)(2t-5) where h is height and t is time in seconds how long was football in the air?
Answer:
2.5 seconds.
Step-by-step explanation:
When the football reaches the ground h = 0, so:
2(-2 - 4t)(2t - 5) = 0
so either -2 - 4t = 0 or 2t - 5 = 0
so -4t = 2 or 2t = 5
t = -1/2 , t = 5/2 = 2.5 seconds.
WE ignore the negative t , so
Time that the ball was in the air = 2.5 seconds.
3(2x-4)=3X-3. What is the x?
Answer:
x = 3
Step-by-step explanation:
Distributive property: a(b + c) = (a*b) + (a*c)
3(2x - 4) = 3x - 3
3*2x - 3*4 = 3x - 3
6x - 12 = 3x - 3 {Add 12 to both sides}
6x -12 + 12 = 3x -3 + 12
6x = 3x + 9 {subtract 3x from both side}
6x - 3x = 3x - 3x + 9
3x = 9 {Divide both sides by 3}
3x/3 = 9/3
x = 3

Kade has $45 in savings and wants to purchase a video game console for $250. He has a coupon for 10% off, and sales tax is 8.25%. In order to be financially responsible, Kade wants to wait until he has enough in savings to not have to borrow money. If Kade is able to save $45 each week, what is the minimum number of weeks Kade should save before making his purchase?
Answer:
5 weeks
Step-by-step explanation:
First, solve for the total cost of the game console after tax and a coupon
Solve for tax:
$250 × 8.25%
Convert percentage into a decimal
250 × 0.0825
20.625
Round up to nearest hundredths place (because the unit is dollars)
20.63
Add this tax onto the original cost
250 + 20.63
270.63
Subtract the coupon from the total
270.63 - 10
260.63
Total cost is $260.63
Now let's find how much Kade needs to save so set up an equation
Variable x = number of weeks
45 + 45x = 260.63
Subtract 45 from both sides to isolate the variable
45x = 215.63
Divide both sides by 45
x = 4.791777...
Round up to nearest whole number (because units are weeks)
x = 5 weeks

Bo invests money in an account paying a simple interest of 8% per year. If no money will be added or removed from the investment, what should he multiply his current balance by to find his total balance in a year in one step?
Answer:
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year,
then, solving our equation
I = Prt (Where p=principle,r=rate,t=time)
I = p*0.08*1=0.08p
Step-by-step explanation:
Bo should multiply his current amount by 1.08 to get the complete balance in one step.
What is the simple interest?Simple interest is defined as interest paid on the original principal and calculated with the following formula:
S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100
We have been given that Bo invests money in an account paying a simple interest of 8% per year.
To find the total balance in a year, you can use the formula:
balance after 1 year = balance × (1 + (interest rate/100))
In this case, the interest rate is 8%, so you can use the formula like this:
balance after 1 year = balance × (1 + (8/100))
This simplifies to:
balance after 1 year = balance × 1.08
Therefore, to find the total balance in one step, Bo should multiply his current balance by 1.08.

Write an equation in standard form for the line that contains the given pair of points.
(3, 8) and (3, -7)
Answer:
x = 3
Step-by-step explanation:
which three statements are true about the line segment CB
it's the radius of the circle
it is the circumference of the circle
it is a cord
it is 6cm long
it is diameter of the circle
it is 7cm long
it is 1.75cm long
Answer:
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
Step-by-step explanation:
Here, we want to select three statements that are true about CB
From what we have, CB runs from one edge to the other, passing through the center of the circle
Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter
The diameter is a chord that passes through the center of the circle and it is a radius
So let us select the correct statements;
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle

Given:
A box-and-whisker plot of data set.
To find:
The percentage of the data values that are greater than 80.
Solution:
From the given box-and-whisker plot, it is clear that:
Minimum value = 8
First quartile = 60
Median = 68
Third quartile = 80
Maximum value = 92
We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.
Therefore, about 25% of the data values that are greater than 80.

can u help me finish setting up the tangent ratio?
This is because
tan(angle) = opposite/adjacent
For the reference angle 38, we have 10 as the opposite side and x as the adjacent side.
Therefore, tan(38) = opposite/adjacent = 10/x
Side note: if you solve for x, you should get roughly x = 12.799

Answer:
y = 5x - 8
Step-by-step explanation:
The linear equation in slope intercept form :
y = mx + c
m = slope ; c = intercept
m = Rise / Run = (y2 - y1) / (x2 - x 1)
Rise = (y2 - y1) = (12 - (-8)) = (12 + 8) = 20
Run = (x2 - x1) = (4 - 0) = 4
Slope, m = Rise / Run = 20 /4 = 5
Hence,
y = 5x + c
For the points ; y = 12 ; x = 4 ; we could obtain c
12 = 5(4) + c
12 = 20 + c
12 - 20 = c
-8 = c
The equation becomes :
y = 5x - 8

Eighteen students decide they don't want to be
rescued and want to continue to live in the
jungle. If this represents 40% of the students,
how many students want to be rescued?
Type your answer into the box to continue.
Answer: 45
Step-by-step explanation:
18 = 40% N
18 = 0.4 N
Divide both sides by 0.4
N = 45
There are 45 students want to be rescued.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Eighteen students decide they don't want to be rescued and want to continue to live in the jungle.
And, This represents 40% of the students.
Now,
Let the number of students want to be rescued = x
So, We can formulate;
⇒ 40% of x = 18
Solve for x as;
⇒ 40/100 × x = 18
⇒ 40x = 1,800
⇒ x = 1800/40
⇒ x = 45
Thus, The number of students want to be rescued = 45

Lawrence found a shirt he liked in the clearance aisle for 15% off the original price. If the original price of the shirt was $35, how much will Lawrence be saving when he buys it?
Answer:
15/100 x 35 = $5.25
Of means multiplication
Always consider a percent as a fraction but it has to be out of 100.
A way to remember that is that the word "cent" means 100. So you multiply the two numbers (divide at the end 21/4 = 5.25)
