Answer:

Step-by-step explanation:

D. No solution

This is simply because -3x-6 cannot equal -3x-7 because -6 and -7 are different numbers therefore x is a false statement.

Calculate the volume of the composite shape please please help giving brainliest!!

Ilya [14]

${\qquad\qquad\huge\underline{{\sf Answer}}}$

There are two hemispheres in there with radius 3 cm, so we can consider it as a whole one. and the other shape in between is Cylinder with radius 3 cm and height 4 cm.

Volume of whole ahape = volume of Cylinder + volume of sphere ~

Volume of sphere :

$\qquad \sf \dashrightarrow \: \cfrac{4}{3} \pi {r}^{3}$

$\qquad \sf \dashrightarrow \: \cfrac{4}{3} \sdot3.14 \sdot {(3)}^{3}$

$\qquad \sf \dashrightarrow \: (4 )\sdot(3.14) \sdot(9)$

$\qquad \sf \dashrightarrow \: 113.04 \: \: cm {}^{3}$

Volume of Cylinder :

$\qquad \sf \dashrightarrow \: \pi {r}^{2} h$

$\qquad \sf \dashrightarrow \: 3.14 \cdot(3) {}^{2} \sdot4$

$\qquad \sf \dashrightarrow \: 3.14 \sdot(9) \sdot(4)$

$\qquad \sf \dashrightarrow \: 113.04 \: \: cm {}^{3}$

Volume of whole shape :

$\qquad \sf \dashrightarrow \: 113.04 + 113.04 = 226.08 \: \: cm {}^{3}$

$\qquad \sf \dashrightarrow \: 226.08 \: \: cm {}^{3}$

geniusboy [140]

Answer:

$m$

Step-by-step explanation:

Part 1) Find the measure of angle 1

we know that

$m$ -----> by supplementary angles

$m$

Part 2) Find the measure of angle 2

we know that

$m$ -----> by alternate exterior angles

Part 3) Find the measure of angle 3

we know that

$m$ -----> by vertical angles

Part 4) Find the measure of angle 4

we know that

$m$ ------> by corresponding angles

Part 5) Find the measure of angle 5

we know that

$m$ -----> by vertical angles

$m$

Part 6) Find the measure of angle 6

we know that

$m$ -----> by supplementary angles

we have

$m$

substitute

$86\°+m$
