Answer:
Find out the number of video games that Jasmine can buy with her savings .
To proof
Let us assume that the number of video games Jasmine can buy be x .
As given
Jasmine wants to use her savings of $1128 to buy video games and music CDs.
The total price of the music CDs she bought was $72. The video games cost $43 each.
Than the equation becomes
72 + 43× x = 1128
simplify
72 + 43x = 1128
43x = 1128 - 72
43x = 1056
x = 24.6 (approx)
Take
x = 24
Therefore the maximum number of video games that Jasmine can buy with her savings be 24 .
Step-by-step explanation:
The maximum number of video games that Jasmine can buy with her savings is... 24 ✅
Allow me to explain...
First, subtract $72 from $1,128
1,128 - 72 = 1,056
⬆️ ⬆️
Then, divide $1,056 by $43
1,056 ÷ 43 = 24.5581...
⬆️ ⬆️
Coming to the conclusion that Jasmine only has enough money for a maximum of 24 video games. ✅

Suppose that x and y vary inversely. Write a function that models the inverse variation.
x=-52 when y=1/4
The required function based on the given conditions is y = 13 / x.
What is a function?
A function is defined as an expression or rule that specifies the relationship between two variables or objects, out of which one is dependent and the other is an independent variable. The image of each and every element is unique.
Examining the function which satisfies the given conditions
Given values of x = 52 and y = ¼
Consider a function such that x and y vary inversely with each other,
y = k / x, where k is a constant —-- 1
Putting values of c and y, we get,
¼ = k / 52
52 / 4 = k
k = 13
Put the value of k in equation 1, we get,
y = 13 / x
Hence, the required function is given by, y = 13 / x.

Four times the sum of a number and two is equal to twice the number
Answer:
number is - 4
Step-by-step explanation:
let the number be n then 4 times the sum of the number and 2 is 4(n + 2)
4(n + 2) = 2n
4n + 8 = 2n ( subtract 2n from both sides )
2n + 8 = 0 ( subtract 8 from both sides )
2n = - 8 ( divide both sides by 2 )
n = - 4
the number is - 4

Quadrilateral MNOP below is a rectangle, and ∠M = 3x + 6. What is the value of x?
The value of x would be 28 and the measure of angle M will be 90 degrees.
What is a rectangle?That parallelogram in which adjacent sides are perpendicular to each other is called a rectangle.
A rectangle is always a parallelogram and a quadrilateral but reverse statement may or may not be true.
WE have been given the Quadrilateral MNOP is a rectangle, and ∠M = 3x + 6.
WE know that interior angle of the rectangle are 90 degrees each.
Therefore,
∠M = 3x + 6 = 90
3x + 6 = 90
3x = 90 - 6
3x = 84
x = 84/3
x = 28
Hence, the value of x would be 28 and the measure of angle M will be 90 degrees.

When numbers are in scientific notation, we can divide in two separate steps.
First, let's divide the powers of ten, then we will divide the other numbers.
Because of the properties of exponents, we can subtract the exponent in the denominator from the exponent in the numerator to divide the powers of 10.
Now we can divide the numbers that are not powers of 10.
The problem asks us to round to two decimal places, so our final answer will have three digits including the ones place. Let's round
so the final answer will have three digits.
first number is 1.109 and
second number is .109
Now let's put the two results back together.
we get, $1.21
we get number after scientific notation
The movie earned $1.21×10^7 in revenue per minute.
Scientific Notation is the expression of a number n in the form
a∗10b
where a is an integer such that
1≤|a|<10
and b is an integer too.
Multiplication: To multiply numbers in scientific notation, multiply the decimal numbers. Then add the exponents of the powers of 10. Place the new power of 10 with the decimal in scientific notation form. If your decimal number is greater than 10, count the number of times the decimal moves to the left, and add this number to the exponent.
Division: To divide numbers in scientific notation, first divide the decimal numbers. Then subtract the exponents of your power of 10. Place the new power of 10 with the decimal in scientific notation form. If the resulting decimal number is less than 1, move the decimal point to the right and decrease the exponent by the number of places that the decimal point moved.
Large Numbers in Standard Form
n=101325=1.01325∗105
(Move the decimal point 5 places to the right)
Express Small Numbers in Standard Form
n=0.00092=9.2∗10−4
(Move the decimal point 4 places to the left.)
Multiplication:
(2.3∗104)∗(6.6∗107)
First Step -
2.3∗6.6=16.38
Second Step -
104∗107=1011
Because the new decimal number in step one is greater than 10, count the number of places the decimal moves to put the number between 1 and 10. Add this number to the exponent. In this case, the decimal point moves one place, so add 1 to the exponent.

Which two forms of exponential functions are there?
Exponential growth and decay are the two different kinds of exponential functions. When b > 1, the function f (x) = bx represents exponential development. If 0 b 1, then the function f (x) = bx depicts exponential decay.What does Y mean in the exponential growth equation?
The variables y, a, r, and t represent the ultimate amount, growth rate, and decay rate, respectively, in the exponential growth and decay formulas. Growth exponential: y = a (1 + r)t.

An 8-yard roll of tape costs $3.04. What is the unit price?
The unit price for the tape is $0.38 or 38 cents per yard.
The unit price is the price of one unit of measurement for a particular substance.
The unit price of a substance is used to calculate the total cost of a particular substance or the cost of a fraction of a substance.
Unit price is calculated by dividing the total cost by the total quantity of the product.
The given price of the product is $3.04 for a 8-yard roll of tape.
So to find the unit price we divide the total cost by the total length to find the cost of 1 yard of tape.
Unit price = $3.04 ÷ 8
or, Unit price = $ 0.38
Therefore the unit price of the tape is $0.38 or 38 cents.

A truck that can carry no more than 6300 lb is being used to transport refrigerators and upright pianos. Each refrigerator weighs 300 lb and each piano weighs 425 lb. Write and graph an inequality to show how many refrigerators and how many pianos the truck could carry. Will 11 refrigerators and 8 pianos overload the truck? Explain.
The inequality for the load in truck is 300r + 425p ≤ 6300.
11 refrigerators and 8 pianos will overload the truck.
Given,
The carrying capacity of truck = 6300 lbs
The truck is used to transport refrigerators and pianos.
The weight of 1 refrigerator = 300 lb
The weight of 1 piano = 425 lb
We have to find an inequality which shows the number of refrigerators and pianos could the truck carry.
Let's take the number of refrigerators as r and number of pianos as p.
We can equate by using their weights:
That is,
300r + 425p ≤ 6300
Next, we need to determine that, will 11 refrigerators and 8 pianos overload the truck:
We have to multiply the given number with their weights:
That is,
(300 × 11) + (425 × 8) = 3300 + 3400 = 6700
6700 is greater than 6300.
So, we can conclude that 11 refrigerators and 8 pianos will overload the truck.

the pool. How many hours did Julie use the pool
in August?
Answer: 40 hours
Step-by-step explanation:
As stated in the question the total amount spent in the month of august is $35.
First of all you have to subtract 15 out of the entire amount spent so that you can start calculating how many hours did Julie use the pool.

The given expression can be solved by finding the square root of the terms if possible and expressing the terms in the simplest form.
The square root of a number is the factor (number) that can be multiplied by itself to get that number (within the square root sign). Finding the square root of a number can be seen as the opposite of squaring a number. In the general form, √a*a=a.
In the given expression, the numerator √6 cannot be further simplified.
√6=√2*3
We cannot take square root as the number is not multiplying itself.
In the denominator √36 can be further simplified.
