Oliver took a taxi from his house to the airport. The taxi company charged a pick-up
fee of $4.70 plus $4.75 per mile. The total fare was $18.95, not including the tip.
Write and solve an equation which can be used to determine m, the number of miles
in the taxi ride.
Answer:
$4.70 + $4.75m = $18.95 which is 3 miles in total.
Step-by-step explanation:
First make the numbers without the variables on one side.
4.75m = 18.95-4.70
Then subtract.
4.75m = 14.25
Finally divide the two numbers.
14.25 ÷ 4.75 = 3 miles
Answer: m = 3 or 3 miles
Answer:
3 miles
Step-by-step explanation:
Pick up fee = $4.70
Charge = $4.75 per mile therefore this is expressed as 4.75 x m (or 4.75m)
18.95 = 4.7 + 4.75m (add the pick up fee plus fare per mile)
Subtract 4.7 from both sides then divide 4.75 from both sides.
This leaves you with m = 3

Tamir wants to rewrite 13+ 65 using the greatest common factor and the distributive
property.
Complete the statements below.
The greatest common factor of 13 and 65 is ___
….
Answer:
give brainliest please I need it to level up
Step-by-step explanation:
the gcf of 13 and 65 is 13
13 + 65 can be rewritten using the gcf as
13( 1 + 5)
The greatest common factor of 13 and 65 is 13.
The 13 + 65 could be written using the gcf as 13(1 + 5).
Given that,
There are two numbers i.e. 13 and 65.There should be the plus sign i.e. 13 + 65.Here we need to find out the greatest common factor and the rewritten values.Based on the above information, the calculation is as follows:
The GCF is 13
And, it could be rewritten as 13(1 + 5).

On a map, 1 inch equals 15.4 miles. If two cities are 3.5 inches apart on the map, how far are they actually apart?
Answer:
They are actually 53.9 miles away.
Step-by-step explanation:
1 in = 15.4 mi
Set up an equation:
Variable x = number of miles
1/15.4 = 3.5/x
Cross multiply:
1 × x = 15.4 × 3.5
x = 53.9
The volume of a sphere is 367 ft. What is the radius of the sphere? Use the formula V = ar to find your answer.
Answer:
Answer: Radius is 3 ft
Step-by-step explanation:
Formular:
[tex]{ \boxed{V = \frac{4}{3} \pi {r}^{3} }} \\ [/tex]
substitute:
[tex]36\pi = \frac{4}{3} \pi {r}^{3} [/tex]
multiply all sides by 3:
[tex](36\pi \times 3) = ( \frac{4}{3} \pi {r}^{3} ) \times 3 \\ \\ 108\pi = 4\pi {r}^{3} [/tex]
divide all sides by π :
[tex] \frac{108\pi}{\pi} = \frac{4\pi {r}^{3} }{\pi} \\ \\ 108 = 4 {r}^{3} [/tex]
divide all sides by 4:
[tex] \frac{108}{4} = \frac{4 {r}^{3} }{4} \\ \\ {r}^{3} = 27[/tex]
take a cube root:
[tex] \sqrt[3]{ {r}^{3} } = \sqrt[3]{27} \\ r = \sqrt[3]{(3 \times 3 \times 3)} \\ r = \sqrt[3]{ {3}^{3} } \\ \\ r = 3[/tex]

Write an equation of the line passing through point P that is perpendicular to the given line:
P(6, 0) y=4
Answer:
x=6
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is one of those things that will drive you insane until you understand the answer.
Every y value is 4 no matter what x is.
The perpendicular will meet y = 4 at the point (6,4)
Answer: So the equation has to be x = 6.
The blue line is y = 4
The red line is x = 6

Answer the questions below.
(a) The area of a rectangular parking lot is 5673 m².
If the width of the parking lot is 61 m, what is its length?
Length of the parking lot:
(b) The perimeter of a rectangular pool is 292 m.
If the length of the pool is 88 m, what is its width?
Width of the pool:
Step-by-step explanation:
#1
Length = Area/Width
Length = 5673/61
Length = 91 m
#2
Perimeter = 2(l + w)
292 = 2(88 + w)
292/2 = 88 + w
146 = 88 + w
146 - 88 = w
58 = w

If a number is increased by 14 and the result is multiplied by 2/3, the answer is 60. Find the original number.
Answer:
76
Step-by-step explanation:
Firstly I called the original number 'y'
Then i formulated an equation by adding in the processes mentioned in the question: (y + 14) x 2/3 = 60
Then i solved the equation
First I multiplied (y + 14) by 2/3: (y + 14) x 2/3 = (2/3 x y) + (14 x 2/3) = 2y/3 + 28/3
I simplified that to 2y + 28/3 = 60 since you can add fractions which have the same denominator
Then to get rid of the fraction i multiplied both sides by 3 to get 2y + 28 = 180
Then i took away 28 from both sides to get 2y = 152
Then i divided both sides by 2 to get 'y'(the original number) on its on: y = 76

Which product will be rational
Answer:
Option A.
Step-by-step explanation:
A rational number is a number that can be expressed in a fraction (ratio of integers).
Option A is rational since both quantity are rational
Option B is irrational since
[tex]\sqrt{3}\cdot\sqrt{9}=\sqrt{27}[/tex]
where 27 is not a square of any fractions/ integers. Hence, it cannot be expressed as a fraction and is irrational.
Option C is irrational. Note that PI is irrational. Any rational multiples of an irrational number must also be irrational.
Option D is irrational. Similar to Option B.
