The answer is D.
This is because 1/8 and 4/32 are equivalent, and 12.5% is the percentage.

judy got 117 problems right on a math test in her night school class. She got a score of 78% right. How many problems were on th

scZoUnD [109]

You would set this up as Part÷Whole=Percent÷100
Part=117
Whole= X
Percent=78
117÷X=78÷100
Set these up as fractions and cross multiply. You will get 117×100=78X
117×100=11,700
Divide both sides by 78 and you get x=150
There were 150 problems

Find P on AB that is 2/3 of the distance from A(-3,-5) to B(9,4).

Ludmilka [50]

A line segment can be divided into ratios.

The coordinate of P on line segment AB is (5,1)

Given

$A = (-3,-5)$

$B = (9,4)$

The position of P from A to B is:

$P_A = \frac 23$

So, from P to B would be:

$P_B =1 - \frac 23$

$P_B = \frac 13$

So, the ratio is:

$m : n = \frac 23 : \frac 13$

Simplify

$m : n = 2 :1$

The coordinate of point P is:

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

So, we have:

$P = (\frac{2 \times 9 + 1 \times -3}{2 + 1},\frac{2 \times 4 + 1 \times -5}{2 + 1})$

$P = (\frac{15}{3},\frac{3}{3})$

$P = (5,1)$

Hence, the coordinate of P is (5,1)

Please really need the correct answer for this or I'll fail algebra 3

trapecia [35]

Answer:

$4\pi$

Step-by-step explanation:

S = Arc Lenth

θ = Radians

R = Radius

S = θR

So, now that we understand the formula, we will convert 72° into radians by introducing the equation $x*\frac{\pi }{180}$ , x = 72

S = $72*\frac{\pi }{180} * R$

given that R = 10

S = $\frac{72*10*\pi }{180}$

S = $\frac{720*\pi }{180}$

We simplify 720 as 180 goes into 720 4 times and we get

S = $4\pi$

Hope this helps
