IRINA_888 [86]

Answer:

c≤8

Step-by-step explanation:

Let c be the number of copies that you can make

Each copy is 25 cents or .25

It must be less than or equal to 2 dollars

.25c ≤2.00

Divide each side by .25

.25c/.25 ≤ 2.00/.25

c≤8

Maria wraps the gift she is taking to a friend’s birthday party. She doesn’t have much paper, so she does not overlap any of the
Elina [12.6K]

Answer:

Total paper required to wrap the gift without any overlaps: 2700\ cm^{2}

Step-by-step explanation:

Here, we need to find the total paper required without any sides overlapping to wrap the gift.

The gift is of <em>cuboid </em>type.

Given the following:

<em>Length </em>= 15 cm

<em>Width </em>= 30 cm

<em>Height </em>= 20 cm

Please refer to the attached figure.

We can infer that to find the paper required, we actually need to the find the<em> total surface area of the cuboid</em>.

Because the gift wrap will be done <em>on the faces of gift</em> (which is of cuboid shape).

Formula for Surface Area of <em>Cuboid:</em>

\text {Area = } 2 \times (\text{Length}\times \text{Width} + \text{Width}\times \text{Height} + \text{Length}\times \text{Height} )\\\\\Rightarrow 2 \times (15 \times 30 + 30 \times 20 + 15 \times  20)\\\Rightarrow 2 \times (450 + 600 + 300)\\\Rightarrow 2 \times (1350)\\\Rightarrow 2700 cm^{2}

Hence, total paper required to wrap the gift without any overlaps: 2700 cm^{2}

Vaselesa [24]

Using a system of equations, it is found that Debbie worked 45 hours during the week.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Amount of hours worked by Juan.
  • Variable y: Amount of hours worked by Debbie.

Juan and Debbie each earn 9 per hour at their "jobs", and earned a total of 765 for the week, hence:

9x + 9y = 765

Simplifying the expression by 9:

x + y = 85 -> x = 85 - y.

Debbie worked five hours more than juan during the week, hence:

y = x + 5.

Since x = 85 - y, we replace in the expression:

y = 85 - y + 5.

2y = 90.

y = 45.

Debbie worked 45 hours during the week.

Rosa wrote down a fraction on a piece of paper. If you take her fraction and multiply it by eight you get eleven. can you guess
Leviafan [203]

Well 8 times 1.375 equals 11, so we just have to convert 1.375 into a fraction. That means her fraction is \frac{11}{8}, or 1\frac{3}{8}, depending on what kind of fraction she wants.
