Answer:

B

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

p = 180° - (80 + 20)° = 180° - 100° = 80° and

q = 180° - (45 + 55)° = 180° - 100° = 80°

Thus p = q → B

A truck driver drove 48 miles in 45 minutes.At this rate,how many miles can the truck drive in one hour?
murzikaleks [220]

Answer:

64 miles

Step-by-step explanation:

Number of miles driven in 45 minutes = 48 miles

We need to find how many miles will the truck drive drive in one hour. Since the rate is the same, the distance covered in each minute remains the same.

Number of miles driven in 1 minute =  miles

Since, 1 hour = 60 minutes, we can write:

The number of miles driven in 1 hour (60 minutes) =  miles

This means the truck driver can drive 64 miles in an hour.

HOPE THIS HELPS! :)

The sum of the following algebraic expression 2x + 15, 7-8x and 3x - 41 is 30 find the value of x..​
Ksju [112]

\\  \tt  \longmapsto2x + 15 + 7 - 8x + 3x - 41 = 30 \\   \\  \tt  \longmapsto 2x - 8x + 3x + 15 + 7 - 41 = 30 \\  \\  \tt  \longmapsto  - 3x - 19 = 30 \\  \\  \tt  \longmapsto 3x + 19 =  - 30 \\  \\  \tt  \longmapsto 3x =  - 30 -19 \\  \\  \tt  \longmapsto 3x =  - 49 \\  \\  \tt  \longmapsto x = - \frac{49}{3}

PLEASE HELP ME I ONLY HAVE 20 MINUTES!!!!
Over [174]

h(x) = 40x - 16x^2\\h(x) = 15\\40x - 16x^2 = 15\\-16x^2 + 40x - 15 = 0\\

Using the quadratic formula we get

x_1 = 0.5\\x_2 = 2.04

Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds

Boyd’s dartboard is octagonal. Each side measures 9 in. He drew a copy of the board that was smaller by a scale factor 0.25.
Basile [38]
<span>The question is about the side length of a copy of the dartboard. We know that the original dartboard has sides that measure 9 inches. We also have the scale factor 0.25. The ratio of the corresponding sides is called the scale factor. If we have the scale factor 0.25 it means that for 1 unit of the original figure there are 0.25 units of length of a copy. Therefore: x = 9 * 0.25; x = 2.25 in. Answer: The side length of the dartboard Boyd drew is 2.25 inches.</span>
