Final answer:
Lou starts with a roll of fabric that's 9 yards long which equals 27 feet (9 yd x 3 ft/1 yd). After cutting 3 yards (9 feet) and then 4 feet, he's left with 14 feet of fabric.
Explanation:
The question involves calculating the remaining length of fabric in feet after Lou makes two cuts from a roll. Since one yard is equivalent to 3 feet, we'll first convert the roll's total length from yards to feet. Starting with a 9-yard roll, we convert it to feet (9 yd x 3 ft/1 yd = 27 ft). After cutting 3 yards (which equals 9 feet) and then another 4 feet, we subtract these from the total length.
Here's the step-by-step calculation:
Convert initial length to feet: 9 yd x 3 ft/1 yd = 27 ft.
Subtract the first cut in feet: 27 ft - 3 yd (9 ft) = 18 ft remaining.
Subtract the second cut: 18 ft - 4 ft = 14 feet remaining.
Therefore, there are 14 feet of fabric left on the roll.

What is the greatest 3 digit number you can subtract from 426 so that you would need to regroup?
Answer:
419
Step-by-step explanation:
Regrouping in subtraction: If we borrow from one group (tens group) and give to another (Once group) so that the operation can be completed, then this process is called regroup.
For example: We need to find the value of 52-39
[tex]52=50+2[/tex]
[tex]39=30+9[/tex]
We can not subtract 9 from 2. So we will borrow 10 from 50 and give to 2.
[tex]52=40+12[/tex]
Now,
[tex]52-39=(40+12)-(30+9)[/tex]
[tex]52-39=(40-30)+(12-9)[/tex]
[tex]52-39=(10)+(3)[/tex]
[tex]52-39=13[/tex]
We need to find the greatest 3 digit number that can subtract from 426 so that we need to regroup.
To use regroup, the once digit must be more that 6. So, maximum value for once place is 9.
Therefore, the greatest 3 digit number that can subtract from 426 by using regroup is 419.
How do you write " Five less than the product of a number n and 26 is at least 8"
To write 'Five less than the product of a number n and 26 is at least 8', we can use an inequality to represent the given information.
Explanation:To write "Five less than the product of a number n and 26 is at least 8", we can use an inequality to represent the given information. The word "less than" suggests the use of the less than symbol '<'. 'Product' means multiplication, so we have n * 26. The word 'is' indicates the use of the equal sign '=', and 'at least' means greater than or equal to, so we use the greater than or equal to symbol '>='. Combining all the information, the equation becomes:
n * 26 - 5 >= 8
Using this equation, you can find the value of n that satisfies the inequality.
louis has 45 pencils and 75 Pens to divide into gift bags at the fair he does not want to mix the pens and pencils he wants to place an equal amount in each bag what is the greatest number of pens or pencils he can place in each bag
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.
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.
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 :
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.x > 0The quadratic equation that represents the given situation is:

Simplify the above quadratic equation.
[tex]3x^2= 64-16x[/tex]
[tex]3x^2+16x - 64=0[/tex]
Now, factorize the above equation.
[tex]3x^2+24x-8x - 64=0[/tex]
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.

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.
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.

The problem involves mathematical inequalities. We translate the sentence into the inequality 3x - 5 ≥ 16 and solve for 'x', resulting in 'x ≥ 7'. Thus, the number must be 7 or any number above 7.
Explanation:The student's question involves mathematical inequalities. To solve it, let's use 'x' to represent the unknown number in the problem. The question can therefore be translated into the following inequality: 3x - 5 ≥ 16. To find 'x', follow these steps:
Add 5 to both sides of the inequality to undo the subtraction: 3x ≥ 21.Divide both sides of the inequality by 3, to isolate on 'x': x ≥ 7.So, the original sentence 'three times some number decreased by five is no less than 16' is equivalent to the inequality 'x ≥ 7'. Hence, the number must be 7 or any number greater than 7.
