What are the sizes of angles a, b, c and d?

Lilit [14]

Answer:

a = 26°

b = 48°

c = 26°

d = 106°

Step-by-step explanation:

$c + {154}^{o} = {180}^{o} \\ c = {180}^{o} - {154}^{o} \\ c = {26}^{o}$

a = c (Alternate angles)

$a = {26}^{o}$

$b = {48}^{o}$

Corresponding angles

(a + d) + b = 180° (Interior angles)

${26}^{o} + d + {48}^{o} = {180}^{o} \\ d + {74}^{o} = {180}^{o} \\ d = {180}^{o} - {74}^{o} \\ d = {106}^{o}$

A cylinder has a base with a diameter of 10.8 cm and height 15 cm into the volume of a cylinder in a cubic centimeters round you

LekaFEV [45]

Answer:

$V=1,373.44\ cm^3$

Step-by-step explanation:

The correct question is

A cylinder has a base with a diameter of 10.8 centimeters and height 15 centimeters. Enter the volume of the cylinder, in cubic centimeters. Round your answer to the nearest hundredth

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

where

$r=10.8/2=5.4\ cm$ ----> the radius is half the diameter

$h=15\ cm$

assume

$\pi =3.14$

substitute

$V=(3.14)(5.4)^{2} (15)=1,373.44\ cm^3$

Which equation best describes the same line as y - 6 = -4(x+1)

Kobotan [32]

Answer:

y - 6 = -4(x+1) is equivalent to equation C: y = -4x + 2

Step-by-step explanation:

Solve the given y - 6 = -4(x+1) for y and remove the parentheses shown:

y - 6 = -4(x+1) becomes

y = -4(x + 1) + 6, or

y = -4x - 4 + 6, or

y = -4x + 2 This is equivalent to equation C.

The exponentia growth model A=30e^.198026t describes the population by what % is the population of the city increasing each year

Artyom0805 [142]

A=30e^.198026t
= 30(e^.198026)^t
= 30(1.218994087)^t

approximately 21.90% every year
