Answer:

4.4 hours

Step-by-step explanation:

Let the number of hours = x

Ida needs to hire a singer for her wedding.

For Singer A

Singer A is offering his services for an initial $65 in addition to $13.15 per hour.

65 + 13.15x

Singer B

Singer B is offering her services for an initial $73 in addition to $11.35 per hour.

73 + 11.35x

We equate both singers together

Singer A = Singer B

65 + 13.15x = 73 + 11.35x

We collect like terms

13.15x - 11.35x = 73 - 65

1.8x = 8

x = 8/1.8

x = 4.4444444444 hours

Approximately = 4.4 hours

The two singers will charge the same amount of money after 4.4 hours

Course Hero The Pretty Pizza Company wants to open a new pizza place on either the north side of town or the south side of town.
nikitadnepr [17]

Answer:

The Pretty Pizza Company should open a new pizza place on the south area.

Step-by-step explanation:

The population of 15 blocks of the north side of town is 225 people per block, and there are already 36 pizza places in the area.

15*225 = 3375 people

36 pizza places

36/3375 = 0.0106 > 0.1

So not on the north side of the town.

The population of 22 blocks of the south area is 275 people per block, and there are 37 pizza places in the area.

22*275 = 6050 people

37 pizza places

37/6050 = 0.006 < 0.1

So, the Pretty Pizza Company should open a new pizza place on the south area.

The value of the function y= (3/5)t decrease by what percentage of t increases by 1 unit
kirza4 [7]

Answer:

Percent of decrease in the value is 40%.

Step-by-step explanation:

Let's find the value of y when t=1 and t=2 because need to find the decrease by percent of t increases by 1 unit.

When t=1

y=\frac{3}{5}^{1}=0.6

When t=2

y=\frac{3}{5} ^{2} =0.36

Percent of decrease = 100 % -\frac{0.36}{0.6}*100%% = 100% -60% =40%

What is the length of BC in the right triangle below 21 and 72
sleet_krkn [62]
Im guessing 21 and 72 are the side lengths for the triangle?

Alright, so since it's a right triangle you can use the Pythagorean theorem or a^2+b^2=c^2

Since i cant see the picture, im going to use some general math <span>so i</span> can figure out if those two sides are the legs or if one of them is the hypotenuse
Alright 
so im guessing the side we're trying to find is the hypotenuse

21^2+72^2=c^2
441+5184=c^2
5625=c^2
<span>√5625=c</span>
75=c

The answer is 75, hope i helped!
