1.Samantha sells ostrich eggs for $2 each and goose eggs for 0.50. For every dollar she earns, she spends $0.10 on feed. If she sells 5 ostrich eggs and 20 goose eggs, how much money does she have left after buying feeds

Answers

Answer:

$18

Step-by-step explanation:

Sales price of each ostrich egg = $2

Sales price of each goose egg = $0.50

Amount spent after every dollar earned = $0.10

Number of ostrich eggs sold = 5

Number of goose eggs sold = 20

To find:

Total money left after the feeds are bought?

Solution:

First of all, let us find the total money earned by Samantha.

Money earned by selling ostrich eggs = [tex]2\times 5[/tex] = $10

Money earned by selling goose eggs = [tex]20\times 0.50[/tex] = $10

Total money earned by selling both the eggs = 10+10 = $20

Money spent on feeding on every $1 = $0.10

Money spent on feeding on every $20 = 0.10 [tex]\times[/tex] 20 = $2

Total money left after buying feeds = $20 - $2 = $18

hope that helps :))

The total number of tickets given away is 280

How to determine the total number of tickets?

To do this, we make use of the following representations:

c represents childrena represents adultss represents senior

From the question, we have the following equations:

a = 20 + c --- 20 more adult than children

s = 3a ---- 3 times as many senior as adult

c = 40 --- number of children tickets

Substitute c = 40 in a = 20 + c

a = 20 + 40

a = 60

Substitute a = 60 in s = 3a

s = 3 * 60

s = 180

The total number of tickets is:

Total = a + c + s

This gives

Total = 60 + 40 + 180

Evaluate

Total = 280

Hence, the total number of tickets given away is 280

Classify √3.
√3 means "the nonnegative square root of 3."
The square root of a number is a number that when multiplied by itself equals the original number. The radical symbol √ is used to denote the nonnegative square root.

Answers

√ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.

We are given a number √ 3.

We need to classify the number.

First we can see that, this is the non negative square root of the number 3.

That is when we multiply √ 3 two times, we get the number 3.

Also, we can see that, it will be an irrational number as it will be non terminating and non repeating number.

That is it will be a real irrational number.

Therefore, we get that, √ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.

The points (-5, 5) and (5, r) lle on a line with slope -3. Find the missing coordinate r.

Answers

Answer:

r = -25

Step-by-step explanation:

slope is change in "y" over change in "x"

so whatever your change in "x" is between the two points, the change in "y" needs to be in proportion to the slope of -3.

Here the change in "x" is +10, and to make the proportion of the slope equal to -3, the change in "y" needs to be -30.

Starting from the "y" coordinate of 5, a change in "y" of -30 will give you r = -25

So the two points are (-5, 5) and (5, -25)
