Answer: 30°

Explanation: so we know line F has to be 180° because it’s a line. it tells us the angle is 140°, so we know the interior angle is 40° because 180°-140°=40°. we also know that a triangle is 180°. so we have the two angles of the triangle: 110° and 40°. to find the third angle we find 110°+40°+?=180°. once we solve, we know the third angle is 30° because 180°-150°=30°.

hope this helped!

a piece of string is 3 yards long. How many 1 and a quarter yard long pieces can Julie cut from the string?
Georgia [21]
This question is actually a lot simpler than it seems

for a quarter think about money - a quarter is 25 cents or 1/4 of a dollar - so 1 and a quarter yard in decimal form is equivalent to 1.25

now you need to find how many 1 and a quarter yards are in 3 yards - to do this you simply divide 3 by 1.25

3/1.25 = 2.4

so julie can cut 2.4 1 and a quarter long pieces from the string

if you have any questions about how i answered this question please let me know:)

Industrial chemicals are stored in 55-gallon drums. The radius of the drum is 12 inches, and the height is 32 inches. what is th
Drupady [299]

Answer:

The surface area of the drum is 3317.5218 square inches.

Step-by-step explanation:

Drum's have a cylindrical form, therefore in order to calculate its surface area we need to apply the correct formula, as shown below:

area = 2*\pi*r^2 + 2*\pi*r*h

Where the first term of the sum is the area of the lid and bottom of the drum and the second term is the area of the walls of the drum, r is the radius and h is the height. Applying the data from the problem, we have:

area = 2*\pi*12^2 +2*\pi*12*32\\\\area = 3317.5218 \text{ square inches}

The surface area of the drum is 3317.5218 square inches.
