A car traveled 48.36 miles in one hour. What was it's average speed per minute?

Answers

Answer 1

Answer:

0.806 miles per minute

Step-by-step explanation:

There are 60 minutes in an hour, so replace the unit "hour" by 60 minutes and recompute.

... 48.36 mi/h = 48.36 mi/(60 min) = (48.36/60) mi/min = 0.806 mi/min

Answer 2

Final answer:

The car's average speed was calculated by dividing the total distance of 48.36 miles by the total time of 60 minutes, resulting in an average speed of 0.806 miles per minute.

Explanation:

To compute the car's average speed per minute, we need to divide the total distance covered by the total time in minutes. This is because speed is defined as the rate at which an object covers distance. The distance travelled by the car is 48.36 miles (the total distance), and the time is 1 hour. To transform this hour into minutes, we multiply by 60, as there are 60 minutes in an hour. So,

1 hour = 60 minutes

Therefore, to find the average speed, we take the total distance and divide by the total time in minutes. Using this, we find:

Average speed = Total distance / Total time

Average speed = 48.36 miles / 60 minutes = 0.806 miles per minute.

Therefore, the car's average speed was approximately 0.806 miles per minute.

Answers

Let
x-------------> liters of 10% alcohol solution
y-------------> liters of 60% alcohol solution

we know that

A protractor is used to measure an angle. Which of the following could be the measure of the angle if we know it is an acute angle?
125°
75°
0°
it can't be determined

Answers

Final answer:

To find an acute angle using a protractor, choose the angle less than 90°. The acute angle could be 75°.

Explanation:

To determine an acute angle using a protractor, we look for an angle that is less than 90 degrees, as acute angles are those that measure less than 90 degrees.

75° could be the measure of the angle as it falls within the range of acute angles.

Hence, in this case, the angle that could be the measure of the acute angle is 75°.

Final answer:

There are 31 quarter inches in 7 3/4 inches. This is determined by converting the mixed number into an improper fraction and then dividing by ¼, which gives us 31/4 or 31 quarter inches.

Explanation:

The question asks how many quarter inches there are in 7 3/4 inches. To find this, we can convert the mixed number into an improper fraction and then divide by the fraction representing a quarter inch (¼ inch).

First, convert 7 ¾ to an improper fraction by multiplying the whole number 7 by the denominator 4 and then adding the numerator 3. This gives us 28 + 3 = 31, so 7 ¾ inches is equivalent to ⅔31/4 or 31 quarter inches. Therefore, 7 3/4 inches is 31 quarter inches long.

which of the following functions gives the length of the base edge

Answers

The answer is b hope is the correct one

Answer:
a = sqrt(3v/8) which is the first choice

Explanation:
The volume of the right square pyramid is calculated using the following rule:
V = (1/3)*h*a^2 where:
V is the volume
a is the length of the base
h is the height
We are given that the height = 8 in and volume = v, this means that:
v = (1/3)*8*a^2 = (8/3)*a^2

Now, we will solve this equation for a as follows:
v = (8/3)*a^2
3v = 8a^2
3v/8 = a^2
a = sqrt(3v/8) which is the first choice

The graph of g(x) is the graph of f(x) shifted 8 units to the right.

Option D is correct.

What is shifting of a function?

A shift is a rigid translation in that it does not change the shape or size of the graph of the function. All that a shift will do is change the location of the graph. A vertical shift adds/subtracts a constant to/from every y-coordinate while leaving the x-coordinate unchanged.

According to the question

g(x) = f(x – 8)

If the function is shifted to the left it is going to plus(+).

If the function is shifted to the right it is going to minus(-).

Hence, The graph of g(x) is the graph of f(x) shifted 8 units to the right.

Option D is correct.

Jose and Sue are playing a board game. If they land on a red or blue square, they lose 1 point. The inequality statement compares the magnitude of their scores at the end of the game. |−2|<|−5| What does the inequality statement show?

Answers

Final answer:

The inequality statement |−2|<|−5| shows that 2 is less than 5.

Explanation:

In mathematics, an inequality compares two expressions or values, indicating their relative size. Symbols such as < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to) represent inequalities.

The inequality statement |−2|<|−5| compares the magnitude of two numbers, -2 and -5. To find the absolute value of a number, we remove the negative sign. So, |−2| is equal to 2 and |−5| is equal to 5. Therefore, the inequality statement |−2|<|−5| means that 2 is less than 5.

you lease a car valued at 23,495 for 3 years at $429.95/month with a $500 down payment. If interest is 30% of the payment, how much interest is paid over the 3 years?

Answers

(36 payments)*($429.95)*30% = $4,643.46 . . . . interest paid over 3 years

Solution:

Present Value of car= $ 23,495

Down Payment = $ 500

Total Amount paid monthly for 3 years that is 36 months, if you pay $ 429.95 per month=$ 15478.20

Total amount paid for the car as an agreement which includes Down payment of $ 500 as well as monthly Payment of $ 429.95 for 36 months= $ 15478.20+$ 500=$ 15978.20

As, given Interest is 30% of the payment.

So, total interest = 30% of $ 15978

[tex]=\frac{30}{100}\times 15978.20[/tex]

= $ 4793.40

But if you will calculate interest on payment of $ 429.95 at the rate of 30%, it gives

[tex]=\frac{30}{100}\times 429.95[/tex]

= $128.985

So, total interest for 3 years= $128.985 ×36=$ 4643.46

Also, if you will calculate interest on payment of ($500+$429.95=$929.95) at the rate of 30%

[tex]=\frac{30}{100}\times 929.95[/tex]

=$278.985

Total interest for 3 years= $278.985 ×36=$10,043.46

The legs of a right triangle are 12 cm and 16 cm. What is the length of the hypotenuse? 15 cm 17 cm 20 cm 28 cm

**The Pythagorean Theorem only works for right triangles.**

Substitute in the values.
a² + b² = c²
12² + 16² = c²

Solve for c, the hypotenuse.
