It doesn't make sense to find the perimeter of a solid figure. Perimeter is a property of plane (flat) figures.

It is possible to find the surface area, lateral area, or volume of a solid figure. It is possible to find the perimeter of the triangular base of the prism, and then use that perimeter to then find the lateral area. the answer is 6

A kindergarten teacher asked the students’ parents to send their child to school with two fruits (apples and/or oranges). Below

hichkok12 [17]

Answer:

The frequency of oranges is the classroom is 47.37%.

Step-by-step explanation:

The relative frequency of oranges is the number of oranges divided by the total number of fruits.

We have that:

8 students brought 2 apples each. So there are 8*2 = 16 apples

4 students brought an apple and an orange each. So there are 16 + 4*1 = 20 apples and 4*1 = 4 oranges.

7 students brough 2 oranges each. So there are 4 + 2*7 = 18 oranges.

There are 18 oranges, and 20+18 = 38 fruits in total.

So the frequency of oranges in the classrom is

$F = \frac{18}{38} = 0.4737$

Meg is a veterinarian. In a given week, 50% of

krek1111 [17]

Answer:

a. Meg needs to find the part

b. Steve needs to find the percent.

Step-by-step explanation:

The question is incomplete.

This is the complete question:

Meg is a veterinarian. In a given week, 50% of the 16 dogs she saw were Boxers. Steve is also a veterinarian. In the same week, 7 of the 35 dogs he saw this week were Boxers. Each wants to record the part the whole, and the percent.

a. Does Meg need to find the part, the whole, or the percent.

b. Does Steve need to find the part, the whole, or the percent.

<h2>Solution to the problem</h2>

a. Does Meg need to find the part, the whole, or the percent.

Meg already knows the whole and the percent.

The whole is the entire number of dogs seen: 16 dogs.

The percent is 50%.

Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.

And she can do with a simple operation:

Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.

b. Does Steve need to find the part, the whole, or the percent.

He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).

Then he needs to find the percent, which he can do using the next operation:

Percent = (part / whole) × 100 = (7/35)×100 = 20%

A high school athletic department bought 40 soccer uniforms at a cost of $3,000. After soccer season they returned some uniforms

quester [9]

Interesting problem.

First - let's figure cost of each uniform at purchase.

3,000/40 = $75 each

When some uniforms were returned at $40 - there was a difference of $35 in what they paid and what they rec'd in return. ($75 - 35 = $40)

Michael and Lindsey are saving money. Michael begins with $20 and saves $5 per week. Lindsey begins with no money, but saves $10

True [87]

Let
x----------> number of weeks
y----------> saved money

we now that

Michael begins with $20 and saves $5 per week
so
y=20+5x------> equation 1

and
Lindsey begins with no money, but saves $10 per week
y=10x-------> equation 2

the number of weeks it will take for Lindsey and Michael to save the same amount of money is when equation 1 is equals to equation 2

therefore
20+5x=10x------> 10x-5x=20------> 5x=20-----> x=20/5-----> x=4 weeks

the answer is
4 weeks
