I think it is C. 60.
You can eliminate A because it is not a right angle, and D because the angle is bigger than the given angle. So it is between 50 and 60, and I hope this is right and the picture makes sense

The coordinates of the endpoints of directed line sergeant ABC are A(-8,7) and C(7,-13). If AB:BC = 3:2 then the coordinates of

cestrela7 [59]

The correct answer is A) (1,-5)

Further explanation:

Given points are:

A(-8,7)=(x1,y1)

C(7,13)=(x2,y2)

IT is also given that

AB:BC=3:2

Which means that B divides the line segment in 3:2

Here,

m=3

n=2

To find the coordinates of B

$x_B=\frac{mx_2+nx_1}{m+n}\\ = \frac{(3)(7)+(2)(-8)}{3+2}\\=\frac{21-16}{5}\\=\frac{5}{5}\\=1\\y_B=\frac{my_2+ny_1}{m+n}\\=\frac{(3)(-13)+(2)(7)}{3+2}\\=\frac{-39+14}{5}\\=\frac{-25}{5}\\=-5$

The coordinates of point B are (1,-5)

The correct answer is A) (1,-5)

Nora's leaf collection consisted of 150 leaves by August. By december , her collection had grown to 177 leaves. How much did her

Elza [17]

Answer=18%

177/150=1.18

1.18=118%

118%-100%=18%

___________________________
another way to solve the equation...

150 177
_____=_____
100% x

Cross Multiply
150x=17700
divide both sides by 150
x=118%

118%-100%=18%

What is 1.83 as a mixed fraction

lora16 [44]

Answer:

$1\frac{83}{100}$

Step-by-step explanation:

First of all, the number before the decimal would be the whole number of the fraction.

So, $1\frac{?}{?}$

Then, you would put 0.83 over a fraction.

So because you cannot simplify it anymore, it would be $1\frac{83}{100}$

A shoe making company makes 256 pairs of boots in a day how many pairs of boots do they make in 260 days

My name is Ann [436]

Answer:

66560 pairs

Step-by-step explanation:

let the number of pairs of boots the company makes in 260 days = X

1day -----------------256pairs

260days-------------X

cross multiplying

1×X = 260×256

X= 66560

therefore, in 260days, he makes 66560 pairs
