Answer:
12 hours 15 min
Step-by-step explanation:
Melissa has 14 reports to file.
She file 70% of report. She takes average of 1 hour and 15 minutes for each report.
First we find number of reported by Melissa.
Number of reported = 70% of 14
= 9.8
1 hour 15 min [tex]=\dfrac{5}{4}[/tex] hours
For 1 report of file [tex]=\dfrac{5}{4}[/tex] hours
For 9.8 reports of file [tex]=9.8\times \dfrac{5}{4}\approx 12.25[/tex] hours
She will take 12.25 hours to report 70% of them.
12.25 hours = 12 hours 15 min
Hence, Melissa will take 12 hours 15 min to file 70% of report.

To meet building codes, a building must have a roof no taller than 74 feet. An architect is designing a museum with a 14 ½ foot ground floor, and 12 foot 3 inch upper floors (including supports) How many floors, including the ground floor, can the building have?
Answer:
Building can have 4 floors.
Step-by-step explanation:
Height of the ground floor is 14.5 foot and height of upper floors = 12 foot 3 inches or 12.25 foot per floor
Let there are x floors in the building.
Total height of the building = 74 foot
Therefore, total height of the building = Height of the ground floor + Height of the upper floors
74 = 14.5 + 12.25x
74 - 14.5 = 12.25x
12.25x = 59.5
x = [tex]\frac{59.5}{12.25}[/tex]
x = 4.9 floors
Therefore, the building can have 4 floors.

Gina and Danny are playing an addition card game. In the card game, each player takes turns pulling two cards, one at a time, from a deck of cards. If the first card plus the second card is positive, the player keeps those cards. If the answer is zero or negative, the player loses those cards, and the cards go back in the deck.
There are only 10 cards in the deck, which have the following numbers:
(a) If a player gets a first card that is a positive number, what must the second card be in order for the player to keep the cards? Explain your reasoning.
(b) Gina pulls as her first card. What must her second card be in order for her to have a positive answer? List all correct answers and explain why or show your work.
(c) Danny also pulls a as his first card. He pulls a second card and says he has to put the cards back in the deck because he got a negative answer. What card could Danny have pulled? List all correct ans

What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.
Another example could be kilo gram to gram.
Given,
1 gallon ↔ $3.14
Since, 1 gallon = 128 ounce and $1 = 100 cents
128 ounce ↔ 314 cents
So,
1 ounce ↔ 2.453 cents
Now,
Snack-size bottle cost ⇒
1 ounce ↔ 3 cents.
Hence " a gallon of chocolate milk is cheap and batter to buy".

what are three ways you can solve a proportion?
In this exercise we have to explain the three possible methods of solving a proportion, as follows:
1) Vertical
2)Horizontal
3)Diagonal
What is proportion?It is the equality between two or more ratios derived from measurements extracted from quantities. When two ratios have the same result, we say they are proportional. If these ratios represent measures of some magnitude, we also say that they are proportional.
So we know that a proportion is given by the equality between two ratios and the resolution process consists of the following situation: “the product of the extremes is equal to the product of the means” or using the eventual cross multiplication.

What is the coefficient in the expression 2x/7+2
The coefficient of the expression 2x/7 + 2 will be 2/7.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 2x/7 + 2
Now,
The coefficient of x is the number which is multiply with the x.
So, The expression is,
⇒ 2x/7 + 2
⇒ (2/7) x + 2
The coefficient of x in the expression is;

Show how to solve the problem 378 times 6 using place value with regrouping. Explain how you knew when to regroup
Answer:
2268
Step-by-step explanation:
We have to solve the problem 378 dimes 6 using place value.
Place of 8 in 378 = once
Place of 7 in 378 = Tens
Place of 3 in 378 = Hundred
Now we can write this number as ( 300 + 70 + 8 )
( 300 + 70 + 8 ) × 6 = (300) × 6 + 70 × 6 + 8 × 6
= 1800 + 420 + 48

Since a middle school opened, the
girls'
basketball team has had the same record every season. The team has won a total of
84
games while losing only
6
games. Find the constant of proportionality of wins to losses.
The constant of proportionality of the girls' basketball team's record, with 84 wins to 6 losses, is 14.
The constant of proportionality in the context of a basketball team's win-loss record is calculated by dividing the total number of wins by the total number of losses. As the team has won a total of 84 games and lost 6 games, the constant of proportionality is 84 divided by 6, which equals 14. This means that for every loss, the team has approximately 14 wins.

The number m and 58 are additive inverses.
Drag and drop 58 and m to their correct positions on the number line.
Drag and drop the label “Sum” to the sum of 58 and m.
Answer:
[tex]m=-\frac{5}{8}[/tex]
Step-by-step explanation:
We have been given that the number m and 58 are additive inverses.
We know that two numbers are additive inverses when they add up-to 0.
[tex]\frac{5}{8}+m=0[/tex]
[tex]\frac{5}{8}-\frac{5}{8}+m=0-\frac{5}{8}[/tex]
[tex]m=-\frac{5}{8}[/tex]
Therefore, the additive inverse of [tex]\frac{5}{8}[/tex] would be [tex]-\frac{5}{8}[/tex].
