Answer:
The answer is 24.28 square meters.
Step-by-step explanation:
Kwan bought three rolls of regular wrapping paper with 6.7 square meters of paper each.
The paper in three rolls become = [tex]3\times6.7=20.1[/tex] square meter
He also bought a roll of fancy wrapping paper containing 4.18 square meters.
So, total paper that Kwan had is = [tex]20.1+4.18=24.28[/tex] square meter.
Therefore, the answer is 24.28 square meters.
Answer: The answer is 20.1
Step-by-step explanation: To find out how much paper Kwan had altogether, we need to calculate each type's total square meters of wrapping paper and then add them together.
Kwan bought three rolls of regular wrapping paper, each with 6.7 square meters of paper. To find the total square meters for the traditional wrapping paper, we can multiply the number of rolls (3) by the square meters per roll (6.7):
3 rolls * 6.7 square meters/roll = 20.1 square meters
So, Kwan has 20.1 square meters of regular wrapping paper.
In addition, Kwan also bought a roll of fancy wrapping paper, which contains 4.18 square meters.
To find the total amount of wrapping paper Kwan has, we can add the square meters of regular wrapping paper to the square meters of fancy wrapping paper:

While shopping, Kyla found a dress that she would like to purchase, but it costs $52.25 more than she has. Kyla charges $5.50 an hour for babysitting. She wants to figure out how many hours she must babysit to earn $52.25 to buy the dress. Use a double number line to support your answer.
Kyla has to babysit for 9.55 hours to earn $52.50 so that she can buy the dress.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
The dress costs $52.50 more that Kyla has, so she has to earn that much money by babysitting so that she can have the full amount of that dress.
Kyla charges $5.50 for an hour.
So, for $52.50 she has to work for 52.50 divided by 5.50;
52.50/5.50 hours
= 9.55 hours
Therefore, Kyla has to babysit for 9.55 hours to earn $52.50 so that she can buy the dress.

Jake, Becky, and Max are meeting at Charley's Pizza for dinner and then plan to go to a movie. When they arrive at the pizza place, each one of them has a different coupon. They decide to use the coupon that will give them the best deal. Jake's coupon is $19.99 for a pizza and pasta meal deal; Becky's coupon is for two large one-topping pizzas--each at of the menu price; and Max's coupon is for three medium one-topping pizzas -- each at off the menu price. According to the menu, a medium one-topping pizza is $8.99, and a large one-topping pizza is $14.89. They also spend $1.25 each for sodas and $5.00 on the tip. At the movie theater, Max has a coupon that's good for off a third movie ticket when you purchase two other movie tickets at the regular price. The regular price of each movie ticket is $9.80.
Although Jake, Becky, and Max plan to split the cost of the pizza and movie, they decide that with the coupons, it's just easier if one of them pays at each place. So, the friends agree that Jake will pay for the pizza and Becky will pay for the movies. At the end of the night, they'll figure out how much Max owes both Jake and Becky.

One day, I decide to run to the park. On the way there, I run at a rate of x^2 miles per hour for 3 hours. On the way back, I take the same path and jog at a slower rate of 16 - 4x miles per hour so that it takes me 4 hours to get home. Given that x > 0, what is x? Express your answer as a common fraction.
Answer:
8/3
Step-by-step explanation:
Since we know that the distance that I traveled to the park and the distance that I traveled to get back home are the same, and that distance = rate x time, we have that
(x^2)(3)=(16-4x)(4)
3x^2=64-16x
3x^2+16x-64=0
(3x-8)(x+8)=0
Solving this equation, we get the solutions x=8/3 and x=-8. Since x must be positive, we have x=8/3.
The value of x = 8/3 and this can be determined by forming the quadratic equation using the given data and then factorizing it.
Given :

Now, factorize the above equation.

3x(x+8) - 8(x + 8) = 0
(x + 8)(3x - 8) = 0
x = -8 will be rejected because x is always positive. So, the value of x = 8/3.

Stephanie planted a home garden. She planted 2 rows of tomatoes with 5 tomato plants in each row. She also planted squash in rows of 7 plants each.
If x represents the number of rows of squash she planted, which of the following equations can be used to find the total number of plants Stephanie planted in her home garden?
A.
y = 7x + 10
B.
y = 7x + 7
C.
y = 8x + 7
D.
y = 15x + 7
Answer:
A. y = 7x + 10Step-by-step explanation:
The expression we have to find must include the total number of plants.
According to the problem, Stephanie has 2 rows of tomatoes with 5 tomatoes each, that means she has 10 tomato plants, so the expression must have 10 as a term.
You can see already that the only option that has 10 as a term is option A. Therefore, that's the right answer.
In addition, the other plant is represents by 7x, because the problem states that she planted squash in rows of 7 plants, where x expresses rows.

A used electronics store pays $40 for each cell phone, spends $25 refurbishing the phone, and sells the refurbished phone to a customer for $100. Write an expression in simplest form that represents the company's earnings (in dollars) from buying, processing, and selling cell phones. Use x to represent the number of cell phones they sell.
Answer:
[tex]y=35\cdot{x}[/tex]
Step-by-step explanation:
The two expenses for the phones is $40 and $25 per phone. It is sold for $100. The amount of earnings is the sale price of the phone minus the expense for the phone. Let x be the number of phones they sell and y be the earnings. The expression is:

(-3/4+4/3)+a=0
What value of a will make the equation a true statement
The value of A that will satisfy the equation (-3/4 + 4/3) + A = 0 is -7/12 after finding a common denominator and simplifying the fractions.
Explanation:To find the value of a that will make the equation (-3/4 + 4/3) + a = 0 a true statement, we need to first simplify the fraction part of the equation.
Let's find a common denominator for the fractions, which is 12. Converting both fractions, we get:
-3/4 = -9/124/3 = 16/12Now, adding these two fractions we have:
-9/12 + 16/12 = 7/12
So, the equation now is:
7/12 + a = 0
To solve for a, we need to isolate a on one side of the equation:
a = -7/12
Therefore, the value of a that makes the equation true is -7/12.
Explain why it works to break apart a number by place values to multiply
Answer:
We are still multiplying the sum of the addends whose result is those numbers. In other words, we are multiplying those same numbers too.
Step-by-step explanation:
Because when we break apart a number by placing values to multiply like when we do in partial products, we are still multiplying the sum of the addends whose result is those numbers. In other words, we are multiplying those same numbers too.
Check below that Partial Products example:
[tex]46*32=\\46=(40+6)\\32=(30+2)\\(40+6)(30+2)=1200+80+180+120[/tex]
Breaking a number apart by place values then multiply gives the same product as multiply the numbers directly because under multiplication condition, each digit in a number multiplies every other digit in the other value.
Using the expression as an example :
(17 × 12)
17 = 10 + 7 (tens and unit respectively)
12 = 10 + 2 (tens and unit respectively)
17 × 2 = (10 + 7)(10 + 2)
(10 + 7)(10 + 2) = (10×10) + (10×2) + (7×10) + (7×2) (10×10) + (10×2) + (7×10) + (7×2) = 100 + 20 + 70 + 14 = 204Therefore, the product will give the same result always.

Final answer:
The greatest number of pens or pencils that Louis can place in each bag is 15, which is the greatest common divisor of 45 and 75.
Explanation:
How to Find the Largest Number of Pens or Pencils Per Bag
For Louis to place an equal number of pens or pencils in each bag without mixing them and to find the largest number that he can place in each bag, we need to find the greatest common divisor (GCD) of 45 (pencils) and 75 (pens). The GCD is the largest number that can divide both quantities without leaving a remainder.
Let's calculate the GCD of 45 and 75:
List the factors of 45: 1, 3, 5, 9, 15, 45.
List the factors of 75: 1, 3, 5, 15, 25, 75.
Identify the common factors: 1, 3, 5, 15.
The greatest common factor is 15.
Therefore, the greatest number of pens or pencils Louis can place in each bag is 15.
4:189. Estimate the quotient
Final answer:
The estimated quotient of 4 divided by 189 is approximately 0.02, obtained by rounding 189 to 200 for easier calculation.
Explanation:
To estimate the quotient of 4 divided by 189, we can round the numbers to figures that are easier to work with and that will give us a ballpark figure of the actual quotient. Now, 189 can be rounded to 200 for estimation purposes because it is the nearest number that is easy to divide with 4. Then, we divide 4 by the rounded-up figure:
4 ÷ 200 = 0.02
This result indicates that the estimated quotient is 0.02. Keep in mind that this is a rough estimate and the actual quotient will be slightly higher since we rounded 189 up to 200.
