Answer:

Step-by-step explanation:

A would indicate that AE and BD are the same size, which they are not.

B would indicate that BD is larger than AE, which is not true.

C would indicate that AE is twice the size/ larger than BD, which is true, meaning that this statement is true.

D would also mean that AE and BD are the same size, which again is not true.

choli [55]

It will take 5 days for Montegro Flooring Company to complete this job

Solution:

Given, The Montegro Flooring Company can replace 200 square feet of carpet with tile in one day

They accept a job replacing carpet with tile in an apartment that measures 977.5 square feet

We have to find how many days will it take the Montegro Flooring Company to complete this job?

Now, according to given information,

200 square feet ⇒ 1 day

Then, 977.5 square feet ⇒ n days

Now, by chris cross method

$\begin{array}{l}{200 \times n=1 \times 977.5} \\\\ {200 n=977.5} \\\\ {n=\frac{977.5}{200}=4.8875}\end{array}$

Hence, the company requires 5 days approximately.

Two employees are wrapping gifts at the mall. Sally has wrapped seven gifts already and is wrapping at a rate of two gift every

Sunny_sXe [5.5K]

Answer:

It will take them 1.5 hours to wrap the same number of gifts.

Step-by-step explanation:

1. The first thing that we should do is set up two equations to represent the number of gifts that they wrap.

a) Sally: y = 2x + 7

b) John: y = x + 10

Here, y represents the total number of gifts wrapped and x is the number of half hours that pass.

So, what we are saying is that:

a) for every half hour that passes, Sally wraps two gifts, and then she also has 7 gifts that she has already wrapped so we add that on.

b) for every half hour that passes, John wraps one gift, and then he also has 10 gifts that he has already wrapped so we add that on.

2. Now that we have our two equations, we need to find when the number of gifts they have wrapped is equal, ie. when the two equations are equal. Thus, when:

2x + 7 = x + 10

x + 7 = 10 (Subtract x from each side)

x = 3 (Subtract 7 from each side)

Now, remember that x represents the number of half hours, so:

3 half hours = 3*0.5 hours = 1.5 hours

Therefor, it takes them 1.5 hours (or 1 hour and 30 minutes) to wrap the same number of gifts.

printing a newsletter costs $1.50 per copy plus $450 in printers fees. the copies are sold for $3 each. how many copies of the n

svlad2 [7]

Answer:

300 copies of the newsletter must be sold to break even.

Step-by-step explanation:

Let there are k newspapers sold to break even.

Cost price of each paper = $1.50

So, the cost price of k newspapers = k times $1.50 = 1.50 k

Printers fee = $450

Now, total cost of printing k papers = Printing Fee + Cost price of k papers

= $450 + $ 1.50k = 450 + 1.50k

Selling price of each paper = $3

SO, the cost price of k newspapers = k times $3 = 3 k

Now, to break even TOTAL COST = TOTAL SELLING PRICE

or, 450 + 1.50k = 3k

or, 450 = 3k - 1.50k

⇒ 1.5 k = 450

or, k = 450 /1.5 = 300

⇒ k = 300

Hence, 300 copies of the newsletter must be sold to break even.
