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
What's the opposite of -1.5 and 3/4?
Answer:
1.5
- 3/4
Step-by-step explanation:
To find the opposite of a number, you just have to either add or remove a negative sign.
- 1.5 is negative, so the opposite of negative 1.5 is positive 1.5 or 1.5
3/4 is positive, so the opposite of positive 3/4 is negative 3/4 or - 3/4
I Hope That This Helps! :)
Answer:
1.5
- 3/4

Edward wanted to buy a skateboard. The original price of the skateboard was $90. The store was having a sale where everything in the store was markdown 35%, or 35% off. What was the price of the skateboard after the markdown or discount?
Answer:
$58.5Step-by-step explanation:
Step one:
Given data
original price of Skate board= $90
Also there was a 35% discount on the original price.
the idea now is to find what 35% of $90 is.
=(35/100)*90
=0.35*90
=31.5
hence 35% of $90 is $31.5, the discounted price is $31.5
Step two:
The markdown price is the original price- the discounted price
90-31.5= $58.5
Therefore the price of the skateboard is $58.5

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.

Answer:
[-4,3]
Step-by-step explanation:
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.
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

The radius of a circle is 5 kilometers. What is the length of a 90° degree arc?
Answer:
s =5*π/2 km
Step-by-step explanation:
arc length s = rθ
where θ =central angle in radians
r = 5km
θ = 90 degrees = 90 degrees/360degrees * 2π = [tex]\frac{1}{4}[/tex](2π) = π/2
s =5*π/2 km

If two thirds of a number is 56, what is three- quarters of that number?
Answer:
63
Step-by-step explanation: Let n represent the number. If two third of n = 56, n must be 56 times the reciprocal of 2/3 (3/2) 56 time 3/2 = 84. three quarter of 84 is 84 times 3/4 = 63
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.
URGENT MCQ Name the base of the triangle below.
Answer:
base of the triangle is answer c) bcC=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

GEOMETRY The sum of the measures of
the angles of a triangle is 180°.
Find the missing measure.
35°
45
Answer:
Step-by-step explanation:
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°
Remaining angle =X=100° is the answer
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)
Determine the value of x.
