Answer 1

The linear function for the amount of store credit he will have left after purchasing x video games is given as follows:

f(x) = 299 - 60x.

How to obtain alinear function?


The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

The slope m represents the rate of change.The intercept b represents the value of y when x = 0.

The parameters for this problem are given as follows:

b = 299, which is the initial credit that he has.m = -60, as for each videogame purchased, the amount of credit decays by $60.

Maria is renting kayaks from a local shop that charges a $7 fee, plus an hourly rate of $5. 50. For how long can maria rent the kayak if she pays a total of $40?.

Answers

The number of hours Maria rent the kayak for the paid amount of $40 when hourly rate is $5.50 is equal to 6 hours.

Fees of renting charges paid for kayaks from a local shop = $7

Hourly rate = $5.50

Let 't' be the number of hours Maria rent kayak.

Total fees paid by Maria for renting kayak for 't' hours is equal to $40

Required equation to represents the above condition is

$40 = $7 + $5.50t

Simplify the expression to get the value of 't'

⇒ 5.50t = 40 - 7

⇒ t = 33 / 5.50

⇒ t = 6 hours

Therefore, for the number of hours Maria rent kayak by paying total of $40 is equal to 6 hours.

One cubic foot holds 7.48 gallons of​ water, and 1 gallon of water weighs 8.33 pounds. How much does 2.2 cubic feet of water weigh:
In​ pounds?
In​ tons?

So far I Havn't received the correct answer yet.

Answers

To calculate the weight of 2.2 cubic feet of water, first, we need to find the number of gallons of water in 2.2 cubic feet. This can be done by multiplying 2.2 cubic feet by 7.48 gallons/cubic feet:

2.2 cubic feet * 7.48 gallons/cubic foot = 16.53 gallons

Next, we can find the weight of the water in pounds by multiplying the number of gallons by 8.33 pounds/gallon:

16.53 gallons * 8.33 pounds/gallon = 137.53 pounds

So, 2.2 cubic feet of water weighs 137.53 pounds.

To find the weight in tons, we can divide the weight in pounds by 2,000 pounds/ton:

137.53 pounds / 2,000 pounds/ton = 0.0688 tons

So, 2.2 cubic feet of water weighs 0.0688 tons

19.375 pounds is the weight of bike.

What is Unit of Measurement?

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

Given that the  frame of a bike weighs16 pounds.

each tire weighs 9 ounces.

In a bike there are 2 tires, so total weight of tires is 2×9=18 ounces.

The seat weighs 12 ounces

The handlebars weigh 24 ounces.

Convert the ounces to pounds.

We know that 1 pound=16 ounces

So The total number of weight in ounces is 18+12+24=54 ounces

Divide by 16 to convert 54 ounces to pounds

54/16=3.375

Now total weight=16+3.375 pounds

=19.375

Hence, 19.375 pounds is the weight of bike.

A passenger train traveled 240 miles in the same amount of time it took a freight train to travel 160 miles. The rate of the freight train was 20 miles per hour slower than the rate of the passenger train. Find the rate of the passenger train.

Answers

The rate of the passenger's train is given as follows:

60 miles per hour.

What is the relation between velocity, distance and time?

Velocity is distance divided by time, hence the following equation is built to model the relationship between these variables:

v = d/t.

For the passenger train, the equation is given as follows:

v = 240/t.

vt = 240

t = 240/v.

For the freight train, the velocity is 20 miles slower than for the passenger train, hence:

v - 20 = 160/t

v = 160/t + 20.

Replacing the first equation into the second, the rate of the passenger train is obtained as follows:

v = 160v/240 + 20

v = 2v/3 + 20

v/3 = 20

v = 60 miles per hour.

A set contains the numbers 0,6,12 and 15. 2 different numbers are selected randomly from this set. What is the probability that the sum is greater than 12

Answers

Answer:

Step-by-step explanation:

To find the probability of the sum of two randomly selected numbers from a set being greater than 12, we need to first find the total number of possible combinations of two numbers and then count the number of combinations that result in a sum greater than 12.

The set contains four numbers, so there are 4 choose 2 possible combinations of two numbers, which is equal to (4! / (2! * (4 - 2)!)), or 6 combinations. These combinations are:

(0,6), (0,12), (0,15), (6,12), (6,15), (12,15)

Next, we'll count the number of combinations that result in a sum greater than 12. These combinations are:

(6,15), (12,15)

There are 2 combinations that result in a sum greater than 12.

Finally, to find the probability, we'll divide the number of favorable outcomes (combinations with a sum greater than 12) by the total number of outcomes (all possible combinations of two numbers), and express the result as a fraction:

probability = 2 / 6

Reducing the fraction, we get:

probability = 1 / 3

So, the probability that the sum of two randomly selected numbers from the set is greater than 12 is 1/3.

That's how you find the probability of the sum of two randomly selected numbers from a set being greater than a certain value. By counting the number of favorable outcomes and dividing by the total number of possible outcomes, you can find the probability of a certain event.

5 / 5 = 1

So, 5 reduced to its lowest terms is 1.

To make it kid-friendly, you could explain it like this: "We can simplify the fraction 5 by dividing the top and bottom by the biggest number that they both share. In this case, 5 is the biggest number that 5 and 5 share, so we divide both 5 and 5 by 5 to get 1."

Answers

If the diameter of the tub is 8 inches, then the height of gallon tube is,  5.25 inches

What is surface area ?

Surface area is the sum of the areas of all the faces (or surfaces) of a three-dimensional object. It is a measure of how much area the surfaces of an object take up in two dimensions. The surface area of a solid can be found by adding up the areas of its faces.

The surface area of a cylinder can be expressed as:

SA = 2πr² + 2πr x h

where r is the radius of the cylinder, h is its height, and π is the constant pi (3.14).

The diameter of the tub is 8 inches, which means the radius is 4 inches. We are also given that the total surface area is 232.36 square inches.

So we can write:

232.36 = 2(3.14)(4²) + 2(3.14)(4)(h)

Simplifying and solving for h, we get:

232.36 = 100.48 + 25.12h

131.88 = 25.12h

h = 131.88/25.12

h ≈ 5.25 inches

Therefore, the height of the ice cream tub is approximately 5.25 inches.

How do I simplify this into a radical?

Answers

Answer:

Step-by-step explanation:

To simplify the expression X^(12/7) * Y^(35/7) into its simplest form, we need to find the greatest common divisor (GCD) of the exponents 12/7 and 35/7 and divide both exponents by the GCD. Here's the step-by-step process:

Find the GCD of 12/7 and 35/7. To do this, we'll use the Euclidean algorithm method:

a. Divide the larger number, 35, by the smaller number, 12, and get the remainder: 35 ÷ 12 = 2 with a remainder of 11.

b. Divide the smaller number, 12, by the remainder, 11, and get the quotient and remainder: 12 ÷ 11 = 1 with a remainder of 1.

c. The last non-zero remainder, 1, is the GCD of 12/7 and 35/7.

Divide both exponents by the GCD, 1:

a. X^(12/7) becomes X^(12/7 ÷ 1) = X^12.

b. Y^(35/7) becomes Y^(35/7 ÷ 1) = Y^35.

Replace the original exponents in the expression with the simplified exponents: X^12 * Y^35.

So, the expression X^(12/7) * Y^(35/7) is simplified as X^12 * Y^35, which is written as a single radical in its simplest form.
