Answer:

 

D. Yes, he has enough tiles. He needs only 4,256 tiles and will have 144 left over.

Step-by-step explanation

Multiply the width by the length 38x112= 4,256

He has 4,400 tiles and only needs 4,256

4,400- 4,256= 144 left over tiles

The high school dance team is learning a new routine to a song that lasts 3 minutes and 41 seconds, or 221 seconds total. Yesterday, they covered the first 45 seconds of the song at practice. They learn an average of 22 seconds of the dance in an hour. Let h represent the time, in hours, it will take the team to learn the entire dance. Which equation represents this situation, and how long will it take?

Answers

221÷22=h=~10.05     221 secs ÷ 22 secs per h
equation: 45 + 22h =  221

The number of hours it will take is :

22h = 221-45
22h = 176
h = 176/22
h=8
so it takes them 8 more hours to finish learning the song.

The amount of money that is left in a medical savings account is expressed by the equation y=-24x+379, where x represents the number of weeks and y represents the amount of money, in dollars, that is left in the account. After how many weeks will the account have $67 left in it?

Answers

You plug in $67 for y because you need to find out what week you'll have $67 dollars in the account.

The number of weeks required to have $67 left in the account is 13 weeks

Given the Parameters :

Linear equation : y = - 24x + 379

y = amount left in account

x = Number of weeks

To obtain the number of weeks to have $67 left in the account, we substitute y = 67 into the equation and solve for x :

y = - 24x + 379

67 = - 24x + 379

Collect like terms

24x = 379 - 67

24x = 312

x = 312 / 24

x = 13

Therefore, the Number of weeks required is 13 weeks

Use the multiplication table. Describe a pattern you see in rows 3 and 6

Answers

In row Three , the numbers are going by 3 every time and in row 6 the numbers are going by 6 every time.
 

The pattern observed in rows 3 and 6 is that the elements in the 6th row are exactly twice the corresponding elements in the 3rd row.

How to understand the multiplication table

In a multiplication table, each row represents the product of a particular number (the row number) with the numbers in each column. If we consider rows 3 and 6, they represent the products of 3 and 6 with the numbers in each column.

The pattern observed in rows 3 and 6 is that the elements in the 6th row are exactly twice the corresponding elements in the 3rd row.  This pattern holds true because each element in row 6 is twice the corresponding element in row 3.

Stacy and Neil painted 280 ft^2 of their living room wall with 4/5 gallon of paint. How many square feet can they paint with 3 gallons of paint? Enter your answer in the box.

Answers

we know that

Stacy and Neil painted [tex]280\ ft^2[/tex] of their living room wall with [tex]4/5\ gallon[/tex] of paint

so

by proportion

Find how many square feet can they paint with [tex]3[/tex] gallons of paint

[tex]\frac{280}{(4/5)} \frac{\ ft^{2} }{gallons} =\frac{x}{3} \frac{\ ft^{2} }{gallons} \\ \\x* \frac{4}{5} =3*280\\ \\x=\frac{5}{4}*3*280\\ \\x=1,050\ ft^{2}[/tex]

therefore

the answer is

[tex]1,050\ ft^{2}[/tex]

The square feet that can be painted with 3 gallons of paint is  1050 square feet.

The first step to take in order to determine the square feet that can be painted with 3 gallons, the square feet that can be painted with 1 gallon of paint has to be determined.

Number of square feet that can be painted with one gallon = 280 ft² ÷ [tex]\frac{4}{5}[/tex]

280 x [tex]\frac{5}{4}[/tex] = 280 feet

The second step is to determine the square feet can be painted with 3 gallons of paint.

280 feet x 3 = 1050 square feet.

if m<DCF =90 what is m<DCE

Answers

Final answer:

The measure of angle DCE is 90 degrees.

Explanation:

To find m <DCE, we need to use the fact that the angles in a triangle add up to 180 degrees.

Since m <DCF is 90 degrees, this means that DCF is a right angle. Therefore, the sum of m <DCF and m <DCE must be 180 degrees.

So, m <DCE = 180 - 90 = 90 degrees.

Answers

Hi there! So, the amount made is expected to increase by 20% from $25.9 billion next year. To find the projected amount, let’s multiply 25.9 billion by 120% 1.20. Multiply by that number brings us tot he total amount, instead of having to find the amount gained and adding it into the original price. 25,900,000,000 * 1.20 is 31,080,000,000. The projected amount of shoe sales next year is expected to be $31.08 billion.

what is 0.4 as a simplified fraction

Answers

Answer: 2/5

Step-by-step explanation: Using the place value chart, we can see that the decimal 0.4 is four tenths, so we can write 0.4 as the fraction 4/10.

Notice however that 4/10 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 4 and 10 which is 2.

So if we divide the numerator and the denominator by 2, we get the equivalent fraction 2/5.

Therefore, 0.4 can be written as the fraction 2/5 which is in lowest terms.

About how many more hours Avery spend sleeping than doing the activities in the "other" category? Justify your anwser.

Please I need to finish this before tommorow. Here is the graph and this is 7th grade math

Answers

Answer:

So, she spends 3 hours more sleeping than doing the activities.

Step-by-step explanation:

Consider the provided information.

According to the graph, Avery spends 33% of time in sleeping and 19% of time in doing "other" activities.

There are 24 h in a day.

According to Sleep category: 33% of 24 is:

33 % of 24=0.33×24=7.92 h ≈8 hours  

We are rounding to 8 hr because the solution should be in hours as per the question requirement.

Other category: 19% of 24 is:

19 % of 24=0.19×24=4.56 h ≈5 hours  

The difference of time is:

8h-5h=3h

So, she spends 3 hours more sleeping than doing the activities.
