Answer:

The smaller angle is 18 degrees

The larger angle is 72 degrees

Step-by-step explanation:

x = smaller angle

y = larger angle

y = 4x ---> one angle is 4 times larger than other one.

y + x = 90 ----> the sum of complementary angles is 90 degrees

4x + x = 90 ----> plug in 4x for the larger angle (y) and then solve

5x = 90

x = 18 ----> the smaller angle is 18 degrees

y = 90 - 18

y = 72 ----> the larger angle is 72 degrees

4. Find the height of a cylinder whose radius is 7cm and the total surface area is 968 sq.cm

timofeeve [1]

Answer:

<u>Height of the cylinder = 15</u>

Step-by-step explanation:

According to the question, TSA=968

TSA of cylinder=2π r (r+h2*22 / 7*7 (7+h) = 968

2*22 (7+h) = 968

(7+h) = 968/44

7+h=22

h = 22-7

= 15 cm

An officer printer prints 25 photos in 12.5 minutes. A home printer prints 15 photos in 6 minutes. Which printer is faster, How

ollegr [7]

Answer:

The home printer is faster.

Step-by-step explanation:

25 photos in 12.5 minutes

12.5 is half of 25 and therefore this is a two to one ratio.

So 2 photos print in 1 minute with the office printer.

And 4 photos in 2 minutes(this is relevant later)

The home printer prints 15 photos in 6 minutes. Since 15 is not divisible by 6 without a remainder divide both by 3.

So 5 photos in 2 minutes. This is faster than the office printer.

To find how many photos it would print in 12 more minutes, simply multiply 15 by two, since the minutes(6) was multiplied by 2 to get 12. This leaves you with an answer of 30 photos in 12 minutes

Verdich [7]

Answer:

reflected across the y-axis
compressed by a factor of 2

Step-by-step explanation:

Replacing x by -x in f(x) causes it to be reversed horizontally, that is, reflected across the y-axis.

Replacing x by 2x in f(x) causes it to be compressed horizontally by a factor of 2.

Both of these transformations result in g(x) being a horizontally compressed horizontal reflection of f(x).

See the attachment for an example. The blue curve is g(x); the red curve is f(x).
