Answer: You will need 220 feet of ribbon and 5 rolls.
Step-by-step explanation:
Hi, to answer this question we have to multiply the amount of ribbon that each box needs (2 3/4) by the number of boxes (80).
Mathematically speaking:
2 3/4 x 8 = (2x4+3)/4 x 8 = 11/4 x 80 = 880/4 = 220 feet of ribbon
You will need 220 feet of ribbon.
Since each roll of ribbon has 50 feet, we have to divide the total amount of ribbon needed (220) by the amount of ribbon that each roll has (50), to calculate the number of rolls needed.
220/50 = 4.4 rolls =5 rolls (1 roll is not fully used)

a.Two friends share 76 blueberries
To count the blueberries,they can put them into small bowls of 10 blueberries.Draw a picture to show how the blueberries can be shared equally.Will they have to split apart any of the bowls of 10 bluberries when they share them?
To divide 76 blueberries equally into small bowls of 10 blueberries, 7 bowls will be needed. They will need to divide the remaining 6 blueberries equally by adding 1 blueberry to each bowl.
Explanation:To divide 76 blueberries equally into small bowls of 10 blueberries, we will need 7 bowls. Each bowl will contain 10 blueberries, with 6 blueberries left over. Since they cannot split apart a bowl of 10 blueberries, they will need to divide the remaining 6 blueberries equally by adding 1 blueberry to each of the 7 bowls. This way, they will have shared the blueberries equally.

Michelle multiplied 3.4 x 52 She incorrectly wrote 1,768 as her product. Use words, numbers, and/or pictures to explain Michelle's mistake.
Michelle forgot to add the decimal point on her result number.
Further ExplanationWhen multiplying decimal numbers don't forget to put the decimal point. The whole process of multiplying would be the same as the whole numbers multiplication except for the placement of the decimal point in the answer.
For example:
[tex]=\boxed {3.4 \times52\ }\\ =\boxed {176.8\ }[/tex]
The step by step process would be:
3.4 ⇒ the first factor has 1 decimal point
52 x ⇒ the second factor has 0 decimal point
68
170 +
176.8 ⇒ the answer would have 1 decimal point
Unlike the additional decimal numbers, when we are doing the multiplication, we don't need to line up the decimal point, in the case above:
first factor has 1 decimal pointthe second factor has 0 decimal point (a whole number)so the answer would be have 1+0 = 1 decimal pointLearn moreDecimal numbers multiplication https://brainly.com/question/2002881

how to turn 5x+10y=15 in to slope intercept form (y=mx+b)
To convert the equation 5x+10y=15 into the slope-intercept form y=mx+b, subtract 5x from both sides and then divide by 10. The final equation will be y = -0.5x + 1.5, where -0.5 is the slope (m) and 1.5 is the y-intercept (b).
Explanation:Converting the equation 5x+10y=15 into slope-intercept form (y=mx+b) involves isolating y on one side of the equation. The slope-intercept form of an equation is defined such that m is the slope and b is the y-intercept.
Here are the steps to convert this:
Start with the original equation: 5x + 10y = 15.Subtract 5x from both sides to get: 10y = -5x + 15.Divide every term by 10 to isolate y: y = -0.5x + 1.5.The equation is now in the form y = mx + b. Here, the slope, m, is -0.5 and the y intercept, b, is 1.5, which is the point at which the line intercepts the y axis.

Melanie spent four hours babysitting. She charges $16 upfront and then and additional charge per hour. The total amount she earned can be represented by the expression $4x + $16. What expression represents the amount she earns each hour?
The expression representing the amount Melanie earns each hour from babysitting, based on the expression $4x + $16 and her working for four hours, is represented by the variable $x. To determine the hourly rate, we would divide the total hourly charge by the number of hours, but the specific value of $x is not given.
Explanation:The given expression representing Melanie's total earnings from babysitting for four hours is $4x + $16. Here, $16 is the upfront charge and $4x represents the additional hourly charge multiplied by the number of hours worked. To find the expression representing the amount she earns each hour, we look at the variable part of the expression, which is $4x.
Since Melanie worked for four hours, this part of the expression ($4x) must account for her earnings per hour times the number of hours worked. To find her earnings per hour, we divide the total hourly charge by the number of hours. Therefore, the expression for the hourly rate is $x.
To determine the specific amount that x represents, we would need additional information, such as the total amount she earned after working the four hours. However, based on the given expression, we can conclude that x is representative of Melanie's earnings per hour.
The seventh-grade band is going to sell baked goods at the craft show. The cost to rent a booth at the craft show is $60. The band plans to charge $1.50 per baked good. How many baked goods must they sell in order to profit at least $200?
The number of baked goods to have at least a profit of $200 is
94 or more.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
Cost of renting a booth = $60
Charge per baked good = $1.50
The number of baked goods to have a profit of at least $200.
60 + 1.50x ≥200
Solve for x.
60 + 1.50x ≥ 200
Subtract 60 on both sides.
1.50x ≥ 200 - 60
1.50x ≥ 140
Divide both sides by 1.50
x ≥ 140/1.50
x ≥ 93.33
This means,
94 or more baked goods.
Thus,
94 or more baked goods need to be sold to have a profit of at least $200.
