Answer:

It's 14..... I just took the quiz

By applying the above properties of a kite, the length of line segment BC is equal to: B. 14 units.

The properties of a kite.

According to geometry, the adjacent sides of a kite ABCD are always equal and a pair of opposite angles are always equal. Thus, we can logically deduce the following points:

AB = BCCD ≅ AD

By applying the above properties of a kite, the length of line segment BC is equal to 14 units because it's equal to the length of line segment AB.

Solve this problem, and identify the percent, amount, and base.
What percent of 60 is 45?

Answers

over all answerrr 75

The percentage is 75%, the amount is 45 and the base is 60 so option (D) will be correct.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given that 45 is some percentage of 60

So, 60 will be the base because we are calculating the percentage of it and the amount will be 45.

Let's say 45 is x percentage of 60

Then,

60 × x/100 = 45

x = 4500/60

x = 75%

Percentage will be 75

Hence "The percentage is 75%, the amount is 45 and the base is 60".

A college student completed some courses worth 3 credits and some
courses worth 4 credits. The student earned a total of 5% credits after
completing 18 courses. How many courses worth 3 credits did the student
complete?
A. 13
B. 5
C. 20
D. 39

Answers

Answer:

A. 13

Step-by-step explanation:

Note: It seems typo in the question. 5% should read 59.

Let 3 credit courses = x, 4 credit courses = y

As per  given we have following equations:

x + y = 183x + 4y = 59

Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:

4(x + y) - (3x + 4y) = 4(18) - 594x + 4y - 3x - 4y = 72 - 59x = 13

The answer is 13

Correct choice is A

I think its A.

the answer is 12.9045.

which is close to 13.

I hope this helps.
