b. The value of t in the table is 3 years

<h3>Simple Interest</h3>

From the question, we are to solve for t in the given formula

The given formula is the formula for simple interest

I = Prt

To solve for t, we will divide both sides of the equation by Pr

That is,

I/Pr = Prt/Pr

I/Pr = t

∴ t = I/Pr

The formula solved for t is t = I/Pr

b. We are to find the value of t when

I = $75

P = $500

r = 5% = 0.05

From

t = I/Pr

t = 75/(500×0.05)

t = 75/25

t = 3 years

Hence, the value of t in the table is 3 years

Two mechanics worked on a car. The first mechanic worked for 5 hours, and the second mechanic worked for 15 hours. Together they

Lunna [17]

Answer:

The mechanic who worked 5 hours charged $115 per hour, the one who worked 15 hours charged $120 per hour.

Step-by-step explanation:

x = rate of mechanic who worked 5 hours

y = rate of mechanic who worked 15 hours

Then

x + y = 235

5x + 15y = 2375

Just solve these 2 equations above for x and y.

x + y = 235 ⇒ x = 235 - y

Substitute into second equation to find y.

5(235 - y) + 15y = 2375

1175 - 5y + 15y = 2375

10y = 1200

y = 1200/10 = 120

x = 235 - y = 235 - 120 = 115

Against the wind a commercial airline in South America flew 630 miles in 3.5 hours. With a tailwind the return trip took 3 hours

Salsk061 [2.6K]

Answer:

The speed of plane is $195\ mph$ , and speed wind is $15\ mph$ .

Step-by-step explanation:

Given against the wind the airline flew $630$ miles in $3.5$ hours.

including the tailwind the return trip took $3$ hours.

Let speed of plane is $x$ .

Also, speed of the wind is $y$ .

Now, we will find speed on each case.

Speed against the wind is $\frac{630}{3.5}=180\ mph$

Speed with the wind is $\frac{630}{3}=210\ mph$

Now, we will write the equation

$x+y=210\\x-y=180$

Add these equation we get,

$2x=390\\x=\frac{390}{2}\\x=195\ mph$

Now, plug this value in $x+y=210$ to get speed of wind

$195+y=210\\y=210-195\\y=15\ mph$

So, the speed of plane in still air is $195\ mph$ , and speed of the wind is $15\ mph$ .
