Brandon enters a contest at the gym. He earns 1 point for his first workout. If he works out the next day, he earns double the p

oints of the previous day. Brandon creates the graph to show the number of points that can be earned on the nth consecutive day of working out.
A graph shows day of workout labeled 1 to 10 on the horizontal axis and daily points earned on the vertical axis. A line increases from 1 to 7.

How many points will Brandon earn on day 8 if he works out each of the previous 7 days?

Answer:

128

Step-by-step explanation:

You start out with one point on day one. The second day, your points are doubled. Each day after that is doubled from the previous day. So, the second day, you have 2 points. Multiply that by 2 to get 4 for day three.

Day four:4 x 2 = 8.

Day five: 8 x 2 = 16.

Day six: 16 x 2 = 32

Day seven: 32 x 2 = 64

Day eight: 64 x 2 = 128

Answer:

It is 39 cupcakes.

Since he charges $2 per cupcake (39), it is 78.

He makes profit so subtract 30 from 78 and you get $48.

Determine whether the given measures can be the lengths of the sides of a triangle write yes or no
ohaa [14]

NO.,the given measures can not be the lengths of the sides of a triangle

Step-by-step explanation

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

so, Find the range for the measure of the third side of a triangle given the measures of two sides.

here given measures are 2,2,6

2+2 = 4 which is less than the third side 6

        = 4 < 6    

This not at all a triangle.

Hence, the given measures can not be the lengths of the sides of a triangle

10. What is the measure of angle C?<br> A. 25°<br> B. 30°<br> C. 60°<br> D. 75°
Reil [10]

Answer:

D

Step-by-step explanation:

x + 5 + 3x + C = 180                All triangles have 180 degrees.

4x + 5 + C = 180

But C must be equal to 3x. Notice the markings on the lets of the triangle.

4x + 5 + 3x = 180

7x + 5 = 180                          Subtract 5 from both sides

7x = 180 - 5

7x = 175

x = 25

But angle C = 3x

C = 3*25

C = 75

What is the measure of ∠L?
otez555 [7]
<h3>Answer:  72.54</h3>

====================================================

Explanation:

We set up a cosine ratio, since we want to connect the adjacent and hypotenuse. Then we'll use the inverse cosine, which is also known as arccosine, to isolate the angle value.

This is what your steps could look like:

cos(angle) = adjacent/hypotenuse

cos(L) = LM/LN

cos(L) = 18/60

cos(L) = 0.3

L = arccos(0.3)

L = 72.542396876278 which is approximate

L = 72.54 degrees approximately

Make sure your calculator is in degree mode.
