I believe the answer is 20.

C= 15n + 85

$385= 15n+85

$385-85= 300

300/15= 20

20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th

jeka94

Answer:

Step-by-step explanation:

Given tq equation of the height reached by the rocket as y=-16x^2+235x+133

The velocity of the object at its maximum height is zero

v = dy/dx = 0(at max height)

v =-32x +235

0 =-32x+235

x = 235/32

x = 7.34

Hence the rocket will reach its maximum height after 7.34seconds

Jill and Erika made 4 gallons of lemonade for their lemonade stand. How many quarts did they make if then charge $2:00 per quart

notka56 [123]

Answer:

Number of quarts=16

Money earned=$32

Step-by-step explanation:

Given

4 Gallons of lemonade is prepared
They charge $2 for a quart

1 Gallon= 4 Quarts

Therefore Number of quarts

$= \text{number of gallons} \times 4\\= 4 \times 4\\=16$

Therefore Number of quarts of lemonade prepared by them = 16 quarts

As they charge $2 for each quart

⇒

Total money made if they sell it all

$=\text{number of quarts} \times 2\\= 16 \times 2\\=32$

Therefore, if they are to sell all the lemonade that they prepared

They would earn=$32

Five-sevenths of a number is -35. what is the number?

White raven [17]

So lets write this equation out. Let x be that number we are trying to find.

So five-sevenths is a fraction that is written like this

5/7

when you see the word "of" that means multiplication

so we can write the full equation.

(5/7)x = -35

now we can solve

Multiply both sides by 7

5x = -245

now divide by 5
and we get

x = -49
