A truck can be rented from Company A form ​$130 a day plus $0.30 per mile. Company B charges ​$50 a day plus $0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answers

Answer:

160 miles

Step-by-step explanation:

Company A form ​$130 a day plus $0.30 per mile

Company A = 130 + 0.30x

Company B charges ​$50 a day plus $0.80 per mile

Company B = 50 + 0.80x

Where,

x = number of miles

Equate the cost of company A and company B

130 + 0.30x = 50 + 0.80x

Collect like terms

130 - 50 = 0.80x - 0.30x

80 = 0.50x

Divide both sides by 0.50x

x = 80 / 0.50

= 160

x = 160 miles

The number of miles in a day at which the rental costs for Company A and Company B are the same is 160 miles

C=5(f-32)/9
Make f the subject of the formula
Give answer in the form of aC+b/c

Answers

Answer:

F = [tex]\frac{9C+160}{5}[/tex]

Step-by-step explanation:

Given

C = [tex]\frac{5(F-32)}{9}[/tex] ( multiply both sides by 9 to clear the fraction )

9C = 5(F - 32) ← distribute

9C = 5F - 160 ( add 160 to both sides )

9C + 160 = 5F ( divide both sides by 5 )

[tex]\frac{9C+160}{5}[/tex] = F

Write the equation for a parabola with the focus at
(-1, 4) and the equation of the directrix x = 5.
(x + 1)2 = 3(y-4)
(y-4)2 = 12(x + 1)
(y-2)2 = -3(x – 4)
(y-4)2 = –12(x - 2)

Answers

The answer is (y - 4)2 = -12(x - 2)
Since the graph is facing the left, the starting equation would be (y - k)2 = -4p(x - h).
(h, k) is the vertex of the graph. If you plot the focus and the directrix, you can see that the distance is 6. Divide 6 by 2, thus the vertex should be 3 squares away from the focus and 3 squares away from the directrix. The vertex is (2, 4). And since the distance from the focus to the vertex and the distance from the directrix to the vertex is 3, P = 3.
Insert the numbers in and you should get the last choice.

I am given that p || q. ∠1 and ∠4 are supplementary angles because they form a linear pair, so m∠1 + m∠4 = 180°. ∠4 and ∠8 are also supplementary because of the Same-Side Interior Angles Postulate, so m∠4 + m∠8 = 180°. You can substitute m∠4 + m∠8 for 180° in the first equation above. The result is m∠1 + m∠4 = m∠4 + m∠8. After subtracting m∠4 from each side, I see that m∠1 = m∠8.

A train is traveling at a constant speed and goes 7.5 kilometers in 6 minutes. At that rate:




How far does the train go in 1 minute?
how far does the train go in 100 minutes?

Answers

Answer:

1.25 km in 1 minute

125 km in 100 minutes

Step-by-step explanation:

Find its speed in km/min by dividing the km by number of minutes:

7.5/6

= 1.25

So, the train goes 1.25 km in 1 minute.

Using this speed, find how far it goes in 100 minutes, by multiplying the speed by 100:

1.25(100)

= 125

So, in 100 minutes, the train goes 125 km.

a. The distance travelled by the train in 1 minute, at a constant speed is 1.25 kilometers.

b. The distance travelled by the train in 100 minute, at a constant speed is 125 kilometers.

Given the following data:

Distance = 7.5 kilometersTime = 6 minutes

To find how far (distance) the train go in 1 minute, we would use direct proportion:

7.5 kilometers = 6 minutes

X kilometers = 1 minute

Cross-multiplying, we have:

[tex]6 \times X = 7.5\\\\X = \frac{7.5}{6}[/tex]

X = 1.25 kilometers.

b. To find how far (distance) the train go in 100 minute:

Since the train travels 1.25 kilometers in 1 minute, we would multiply that distance by 100.

[tex]D(100) = 1.25 \times 100\\D(100) = 125 \; kilometers[/tex]

Distance = 125 kilometers.

A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind. Find the speed of the wind if the​ pilot's speed in still air is 315 miles per hour.

Answers

Given:

A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind.

Pilot's speed in still air is 315 miles per hour.

To find:

The speed of the wind.

Solution:

Let the speed of wind be x miles per hour.

Speed with wind = 315+x miles per hour

Speed against wind = 315-x miles per hour

We know that,

[tex]Time=\dfrac{Distance}{Speed}[/tex]

According to the question,

[tex]\dfrac{450}{315+x}=\dfrac{360}{315-x}[/tex]

Divide both sides by 90.

[tex]\dfrac{5}{315+x}=\dfrac{4}{315-x}[/tex]

By cross multiplication, we get

[tex]5(315-x)=4(315+x)[/tex]

[tex]5(315)-5x=4(315)+4x[/tex]

[tex]5(315)-4(315)=4x+5x[/tex]

[tex](5-4)315=9x[/tex]

Divide both sides by 9.

[tex]\dfrac{(1)315}{9}=x[/tex]

[tex]35=x[/tex]

Therefore, the speed of wind is 35 miles per hour.

Jaidee invests $2,628 in a retirement account with a fixed annual interest rate of 2.33% compounded 12 times per year. How long will it take for the account balance to reach $3,726.18?

Answers

Answer:

The time it will take for the account balance to reach $3,726.18 is 15 months.

Step-by-step explanation:

The information provided is:

Jaidee invests $2,628 in a retirement account With a fixed annual interest rate of 2.33% Compounded 12 times per year, i.e. compounded monthly.Final account balance: $3,726.18

The formula of compound interest (compounded monthly) is:

[tex]A=P(1+\frac{r}{12})^{12t}[/tex]

Compute the value of t as follows:

[tex]3726.18=2628\times (1+\frac{0.0233}{12})^{12t}\\\\\frac{3726.18}{2628}= (1.00194167)^{12t}\\\\1.41787671= (1.00194167)^{12t}\\\\\log(1.41787671)= 12t\times \log(1.00194167)\\\\12t=\frac{\log(1.41787671)}{\log(1.00194167)}\\\\t=14.99995\\\\t\approx 15[/tex]

Thus, the time it will take for the account balance to reach $3,726.18 is 15 months.
