Answer:

x=35°

3x= 105°

Step-by-step explanation:

$40 + 3x + x = 180$

$40 + 4x = 180$

$4x = 180 - 40$

$4x = 140$

$x = \frac{140}{4}$

$x = 35$

$3x = 3(35) \\ 105$

Dmitry_Shevchenko [17]

Answer:

Nominee d receive 202 votes.

Step-by-step explanation:

Given : In a poll 303 students voted. Nominee d received $\frac{2}{3}$ of the votes.

To find : How many votes did nominee d receive ?

Solution :

The number of votes = 303

Nominee d received $\frac{2}{3}$ of the votes.

i.e. $n=\frac{2}{3}\times 303$

$n=2\times 101$

$n=202$

Therefore, nominee d receive 202 votes.

Find the volume of a right circular cone that has a height of 17.1 in and a base with a

padilas [110]

Answer:

Volume of the right circular cone = 1188.79 cubic inches

Step-by-step explanation:

Height of the cone = 17.1 inch

Circumference of the cone= 16.3 inches

Radius = 16.3/2

= 8.15 inch

Volume of the cone is:

$=\pi *r^2*\frac{h}{3}$

As, $\pi =\frac{22}{7}=3.14$

Volume of the cone

$=3.14*(8.15*8.15)*\frac{17.1}{3} \\\\=3.14*(8.15*8.15)*5.7\\\\=3.14*66.42*5.7\\\\=3.14*378.59\\\\=1188.79inch^3$

Volume of the right circular cone is 1188.79 cubic inches

Which equation represents the line that passes through the points (-3, 7) and (9,-1)? oy--3x+5 o y=-x-7 o y=zx-7 oy - 12 2x+5

nekit [7.7K]

Answer:

use the slope equation (y2-y1) / (x2 -x1). plug in values and solve

(-1 -7) / (9 -(-3)) (subtracting a negative is the same as adding a positive)

-8 / 12 (simplify)

m = -2/3

then, plug in one of the points and the slope into the slope-point equation.

(y - y1) = m (x - x1) (the point-slope form)

y - 7 = -2/3( x - (-3)) (plug in the slope and point 1 values, then solve)

y - 7 = -2/3x - 2 (add 7 to both sides)

y = 2/3x +5 (the answer)

Step-by-step explanation:

I hope this helps :))
