Just took the test it's 8inches so it's (C)

Volume of cube = 1/3 * pi * r^2 * h
83.74 = 1/3 x 3.14 x r^2 x 5 = 5.233r^2
r^2 = 83.74/5.233 = 16
r = sqrt(16) = 4

Therefore, d = 2(4) = 8 inches.

Find the area of the iscoseles triangle first answer=brainliest
blsea [12.9K]

Answer:

60cm^{2}

Step-by-step explanation:

so first we need to find the height so by splitting the isosceles triangle into two right-angled triangles and then applying Pythagoras' Theorem to one of them.

h^{2} =13^{2} -5^{2}

h^{2} =169-25

h^{2} =144

h=\sqrt{144}

h=12

We now know the height of the triangle and can use this to go back and find the area of the isosceles triangle.

area of triangle = \frac{1}{2} x base x height

area of triangle = \frac{1}{2} x 10 x 12

area of triangle = 60

The official run time of a movie is 140 minutes.Your friend who has seen the movie says its about 2.3 hours
Elza [17]
A.
1 hour = 60 minutes ;
2 hour s= 120 minutes;
140 - 120 = 20 minutes ;
20 = 60 ÷ 3 ;
20 minutes represents ( 1 / 3 ) hour;
Then, 140 minutes represents 2 1 / 3 hours ;
2 1 / 3 = 7 / 3 = 2.(3) ;
B.
2.(3) > 2.3 ;
your friend underestimate the length of the movie ;

PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!!
jenyasd209 [6]

Answer:

x= -1/3

y= -3 1/3

Step-by-step explanation:

Make both of them into y=Mx+b form

y=-x-3

y=(-x-7)/2

Substitute the x-3 in the first equation for the y in the second one.

x-3=(-x-7)/2

2x-6=-x-7

3x=-1

x=-1/3

Now that we have x, we can solve for y.

y=-x-3

y=-1/3-3

y=-3 1/3
