Answer:
175ft an hour
Step-by-step explanation: lets say t=hours
so 2t=400ft and 6t=700ft
the difference between hours is 4 because 6-4=2
so we would multiply 4 by ?
to get the missing # you would have to multiple 4 by numbers between 170 and 190 because anything under 170 is no where near 175 and anything above 190 is way off 175. Answer is 175ft per hour
Answer:
total distance =700+400ft
time =2+8 =10hour
rate =distance/time=1100/10=110 ft/hour
since he stops two times
rate of change =110/2=75ft/hour

The domain is the left-right (horizontal) extent of the function. The dots at the end of the continuous line are solid, so the brackets on the interval are square brackets.
The left dot is at x=-4; the right dot is at x=3, so the domain is ...

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.
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.
please help! no rush though :)

Sum of all three angle in a triangle=180
Given angles are 35°,45°
Let the remaining angle =x
So 35 +45+X=180
X=180-80
X=100°

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

Answer:
2.55%
Step-by-step explanation:
You have 11 years to make $500, To do this, take the 11 and multiply it by the percentage, after that, do $2000 divided by 11 x (percentage) answer. Then you will have the difference, which should roughly equal $556, which is slightly over $500 but you can't have it under so this is the best answer.
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.
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
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.
Answer:
3
Step-by-step explanation:
Replace 8 with 3
Cz angle 4 is equal to 8
Angle 4+Angle 3 is 180⁰
And angle one is equal to angle three

0.139x4=0.556
so he can eat 55 cookies in 80 mins
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?
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 minutesTo 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.

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?
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: $3,726.18The 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.
