Answer:

2.5ft

Step-by-step explanation:

d=2r

r=1/2d

r=1/2*5ft=2.5 ft

Answer:

Slope Intercept Form

Step-by-step explanation:

its the basics

apply distributive property AKA (A • 9b)+(A • 13)

9Ab + 13A

I hope this helps :)

Answer:

a = -3

b = 3

c = 4

Step-by-step explanation:

Let's do this the long way!

[tex]x = \frac{-3 \pm\sqrt{3^2 - 4 \times (-3) \times 4}}{2 \times (-3)}\\-6x = -3 \pm\sqrt{3^2 - 4 \times (-3) \times 4}\\-6x + 3 = \pm\sqrt{3^2 - 4 \times (-3) \times 4}\\(-6x + 3)^2 = 3^2 - 4 \times (-3) \times 4\\36x^2 - 36x + 9 = 9 + 48\\36x^2 - 36x - 48 = 0\\3x^2 - 3x - 4 = 0[/tex]

So a = 3, b = -3, and c = -4

HOWEVER:

When you look at the terms in the solution originally given, the are all the negatives of what we see here.  That however makes sense, as we can simply multiply both sides of the equation to get the results they used:

[tex]3x^2 - 3x - 4 = 0\\-1(3x^2 - 3x - 4) = -1(0)\\-3x^2 + 3x + 4 = 0[/tex]

Answer:

Would it not be 20?

Step-by-step explanation:

Answer:

The answer is 20

Step-by-step explanation:

If 10 pages is 50% of the paper length, to make it equal 100% you just multiply 10X2 or add 10+10 and that equals 20.

Answer:

24.4%

Step-by-step explanation:

Percent is calculated as

[tex]\frac{choice}{total}[/tex] × 100%

The choice here is alternative = 479 and total = 1960, then

percent = [tex]\frac{479}{1960}[/tex] × 100% ≈ 0.24438.... × 100% = 24.4% ( to 1 dec. place )

Answer:

d) P(D|E)

Step-by-step explanation:

E = person exercises

D = person on a diet

Given the expression :

Of all the people who exercise, the probability that a randomly chosen person is on a diet.

This simply refers to a conditional probability whereby the subset from which the probability that a randomly chosen person is on diet is to be calculated is the subset of those who exercise.

In statistical parlance, the statement is expressed as ; the probability of A given B = P(A|B)

In this scenario, we say; the probability that a randomly chosen person is on a diet Given that the person exercise ; P(D|E)

Hence, the answer is D.

Answer:

96$, hope this helps! （＾⊆＾）

Step-by-step explanation:

120 x .20 = 24

120 -24 =$96

Answer:

well, I don't have the computer in front me with this question on it, but i can explain how you would do it.

all points, or in this case vertices, are written like this : (x , y)

the x-axis is the one that lies flat and the y-axis is the one going up and down.

in this graph, the y-axis and x-axis are more than likely not centered. so where the y-axis intersects the x-axis is known as the origin. you will start at the origin for plotting all points.

to plot point A : start at the origin and count to the left 3, and then down 5 and thats point A

for point B : start at the origin, count left 1 and then down 5, that's point B

point C : start at the origin, count left 1 and then down 1, that's point C

point D : count left 3 and then down 1, that's point D

after plotting the points, you just need to play "connect the dots" and make the shape a rectangle.

Start at point A, go right point B, up to point C, left to point D then down back to point A again

Answer:

As an equation, (we'll use x as the variable), that word problem is 3x+7=31.

To solve we'd subtract 7 from both sides to isolate 3x, which gives us 3x=24. Now, to isolate x(unknown number) we would divide both sides by 3. When you divide both sides by 3, you'd get x=8.

Answer:

8 students in a van and 22 in a bus

Step-by-step explanation:

lets use V as the number of students in each van and B as the number in each bus. hs A has filled 8 vans and 8 buses with 240 students in total so 8*V+8*B=240. We can divide by 8 and we will get that V+B=30 so B=30-V. hs B rented 4vans and 1 bus for 54 students so 4*V+1*B=54. we alredy know that B=30-V so we can substitute that in the 2nd equation so 4*V+30-V=54. simplify and we'll get that 3V=24, V=8 and B=30-V=30-8=22
