Answer:
The total amount of money Shanika and her friends want to raise is <u>$2400</u>.
Step-by-step explanation:
Given:
After a storm damages the community center, Shanika and her friends hold fundraising.
After the first event, they raise $240, which is 10% of the total amount that they want to raise.
Now, to find the total amount of money that Shanika and her friends want to raise.
Let the total amount of money that Shanika and her friends want to raise be 
.
As given 10% of fundraise is $240.
So, according to question:
<em>Multiplying both sides by 100 we get:</em>
<em>Dividing both sides by 10 we get:</em>
Therefore, the total amount of money Shanika and her friends want to raise is $2400.
Answer:
12.5 s
Step-by-step explanation:
If acceleration is constant, speed is proportional to time. To increase the speed by 50 km/h, the car will need an additional time given by ...
t/(50 km/h) = (20 s)/(80 km/h)
t = (20 s)(50/80) . . . . . multiply by 50 km/h
t = 12.5 s
It will take 12.5 more seconds for it to reach a speed of 130 km/h.
The area of the polygons compare to π in the way that as
more angles and sides are added to a polygon the polygon becomes closer to a
circle; the perimeter slowly changes to circumference. Π is used to find the
area and circumference of a circle, so as polygons come closer to becoming circles
π becomes more strongly associated to the polygon. You can even use π to find
the approximate area of a circle if you use the same formula (as you would to
find the area of a circle) on a polygon. Another way to go about it is like
this…
You can find the area of a circle if you know the circle’s
circumference by using these steps:
<span>1. Divide the
circumference by π to find the diameter of the circle.</span>
<span>2. Divide the
diameter by 2 to find the radius of the circle.</span>
<span>3. Now that you
have the radius you can use the formula Area= πr2 to find the area of the
circle.</span>
Answer:
y=2/5x+2
slope: 2/5
y=-1/4x+4
y-intercept: 4
Step-by-step explanation
The equation for slope-intercept form is y=mx+b.
m=the slope
b= the y-intercept
The answer is 20.
5*10-5*6=50-30=20
