Answer:

hi

Step-by-step explanation:

Proportions are two fractions (or rational numbers) that are equal to each other.

Fractions are considered equal if both the numerator and denominator can be multiplied or divided by the same constant to get the other fraction.

How you answer this??
AleksandrR [38]

Answer:

$298

Step-by-step explanation:

Profit = Income - Cost

2 tires for 35 each, so total cost is 2*35=70.  Sold for 65 each, so income is 2*65=130. Profit is 130 - 70 = $60.

3 rims for 75 each, so total cost is 3*75=225. Sold 136 each, so income is 3*136=408. Profit is 408 - 225 = $183.

5 headlight covers for 4 each, so total cost is 5*4=20. Sold for 15 each, so income is 5*15=75. Profit is 75 - 20 = $55.

Total profit = 60 + 183 + 55 = $298

If an arrow is shot upward on Mars with a speed of 68 m/s, its height in meters t seconds later is given by
Talja [164]

Answer:

(a) dy/dt = 68 - 3.72t

(b) 64.28m/s

Step-by-step explanation:

Given y = 68t - 1.86t²

Average Speed is rate of chance of distance with respect to time. Written as dy/dt

To obtain dy/dt, we differentiate y with respect to t, doing that, we have

dy/dt = 68 - 2(1.86)t

= 68 - 3.72t

(a) dy/dt = 68 - 3.72t

(b) To estimate the speed when t = 1, we substitute t = 1 in dy/dt .

dy/dt at t = 1 is

68 - 3.72(1)

= 68 - 3.72

= 64.28

The speed at t = 1 is 64.28m/s
