A rental car company charges $77.25 per day to rent a car and $0.12 for every mile
driven. Owen wants to rent a car, knowing that:
He plans to drive 175 miles.
He has at most $330 to spend.
.
.
Write and solve an inequality which can be used to determine x, the number of days
Owen can afford to rent while staying within his budget.
Answer:
Owen can afford to keep and drive the car for 4 days.
Step-by-step explanation:
The total owing on the car rental is R(d) = ($77.25/day)d + ($0.12/mile)m ≤ $330. Substitute 1 for d (that is, the rental is for 1 day) and 175 for m:
R(d) = ($77.25/day)(d days) + ($0.12/mile)(175 miles) ≤ $330
= $77.25d + $21 ≤ $330
This simplifies to $77.25d + $21 ≤ $330, or
$77.25d ≤ $309
Solving this by dividing both sides of the above equation by $77.25, we get
d = ($309)/($77.25) = 4
Owen can afford to keep and drive the car for 4 days.

Suppose you have a bag with 10 black and 10 red balls, with the balls of each color numbered 1 to 10. Suppose you pick two balls uniformly at random from the bag.
a. Show that the probability that you pick a ball of each color is 10/19.
b. Show that the probability that you pick a ball of each color, with the number on the red ball being one less than the number on the black ball, is 9/190.
Answer:
Step-by-step explanation:
[tex]\text{From the given information:}[/tex]
[tex](a)[/tex]
[tex]\text{ P(ball of each color)=P(1st ball is black \& 2nd (red)) + P(1st(red) \& 2nd(black)})[/tex]
[tex]\text{ P(ball of each color)} = {P(1st (black) \times P(2nd \ red \ | \ 1st black) }+P(1st \ red) \times P(2nd \ black \ | \ 1st \ red)}[/tex]
[tex]\text{ P(ball of each color)} = \Big(\dfrac{10}{20}\Big ) \times \Big(\dfrac{10}{19}\Big ) + \Big(\dfrac{10}{20}\Big ) \times \Big(\dfrac{10}{20}\Big )[/tex]
[tex]\text{ P(ball of each color)} = \Big(\dfrac{10}{19}\Big )[/tex]
[tex](b)[/tex]
[tex]\text{If the combination of total no. of black \& red balls with no =10*10 =100}[/tex]
[tex]Then;[/tex]
[tex]\text{the no. of ways red is less than no. of black = 9}[/tex]
[tex]Thus:[/tex]
[tex]\text{P(ball of each color and number on red ball is 1 less than number of black ball is :)}[/tex][tex]= \text{P(ball of each color) * P(red is 1 less than black [] ball of each color)}[/tex]
[tex]=\Big( \dfrac{10}{19}\times \dfrac{9}{100} \Big )[/tex]
[tex]= \dfrac{9}{190}[/tex]

Rationalize denominators when applicable.
sin theta= [tex]\sqrt{\frac{3}{7} }[/tex] given that theta is in quadrant I.
cos theta=
csc theta=
sec theta=
tan theta=
cot theta=
Answer:
See answers below
Step-by-step explanation:
Given that sin theta = √3/√7
Opposite =√3
Hypotenuse = √7
Get the adjacent
Adj² = (√7)²-(√3)²
Adj² = 7-3
Adj² = 4
Adj = √4
Adj = 2
Cos theta = adj/hyp = 2/√7
csc theta= 1/sin theta = 1/(√3/√7) =
√7/√3
sec theta= 1/costheta = 1/(2/√7) = √7/2
tan theta= opp./adj = √3/2
cot theta =1/tan theta = 1/(√3/2) = 2/√3
= 2√3/3

Circle A has a radius of 10 centimeters. and are tangent to circle A.
If AC = 26 cm, what is BC?
A)20cm
B)24cm
C)26cm
D)[tex]2\sqrt{194} cm[/tex]
Step-by-step explanation:
the answer is in the pic I posted! hope It helps...mark brainliest please!
The measure of BC is 24 cm. So, option B is correct.
Important information:
The diagram of a circle A with two tangents.Radius of circle A is 10 cm.AC = 26 cmWe need to find the measure of BC.
Tangent to circle:We have,
AD = AB = 10 cm
We know that the radius of a circle is perpendicular to the tangent at the point of tangency. It means triangle ABC is a right angle triangle.
Using the Pythagoras theorem, we get
[tex](AB)^2+(BC)^2=(AC)^2[/tex]
[tex](10)^2+(BC)^2=(26)^2[/tex]
[tex](BC)^2=676-100[/tex]
[tex](BC)^2=576[/tex]
Taking square root on both sides, we get
[tex]BC=\sqrt{576}[/tex]
[tex]BC=24[/tex]
The measure of BC is 24 cm. So, option B is correct.

How many gallons of 60% antifreeze solution must be mixed with 70 gallons of 20% antifreeze to get a mixture that is 50% antifreeze.
(Round to the nearest whole number)
Answer:
Answer: Add 315 gallons of 70% antifreeze to 90 gallons of 25% antifreeze to make a 60% mixture.
You need to end up a mixture that is 60% antifreeze.
You have 90 gallons of 25% antifreeze, which means it has .25*90 = 22.5 gallons of pure antifreeze mixed with a solvent (probably water).
.
You will add 'x' gallons of 70% antifreeze to make the 60% mixture.
So, at the conclusion, you will have (90+x) gallons 60% 'pure' antifreeze. That can be shown with the equation:
.
.25*90 + .7*x = .6*(90+x)
.
Multiply by 100 to eliminate fractions.
.
25*90 + 70x = 60(90 +x)
.
2250 + 70x = 5400 + 60x
.
10x = 5400 -2250
.
10x = 3150
.
x = 315 gallons of 70% antifreeze.
.
How much will you end up having on hand?
90 + 315 = 405 gallons
.
If it is 60% antifreeze, how much 'pure' antifreeze will be in the mixture?
.6*405 = 243
.
In the original 90 gallons, you have 22.5 gallons of pure antifreeze.
In the additional 315 gallons, you have .7*315 = 220.5 gallons.
22.5+220.5 = 243 gallons

Step-by-step explanation:
To solve for the variable t, you must isolate it on one side of the equation. [tex]-\frac{t}{6.5} =6.4[/tex], multiply both sides of the equation by -6.5 and you will get t = 6.4 * (-6.5) or t = -41.6.

What is 3-6? Please help meeeee
your answer is going to be -3
Answer:
The Answer to 3-6 is -3!
Step-by-step explanation:
Think of it as a regular problem at first, 6-3: Switch the rolls!
6-3= 3 So when you switch the numbers back to 3-6, you get -3.
The answer has to have a negative sign (-) because it is a negative, a number below zero.
3-3= 0, 3 is half of 6, 6 is the number you need to subtract so you have to go below zero because subtraction is all about taking away from that first number. So 3-3= 0, 0-3= -3.

Answer:
k=3/2Step-by-step explanation:
the first point with whole numbers is (2,3), the next is (4,6), then (6,9). from this, we can make a chart
[tex]\frac{x}{y}\frac{2}{3}\frac{4}{6}\frac{6}{9}[/tex] **pretend this is a chart
Remember the formula y=kx. (k means constant)
we need k by itself, so divide by x on both sides
[tex]\frac{y}{x} =k[/tex]
Now substitute in values from the table in place of x&y
It is best to start with the largest pair (as long as the numbers are easy to deal with)
[tex]\frac{9}{6} =k[/tex]
Now simplify that fraction
[tex]\frac{9}{6} becomes\frac{6}{4} becomes\frac{3}{2}[/tex]
if all of the pairs simplify to the same thing, that is the Constant of Proportionality.Answer:
