8. Lesly took a test with 30 questions. The ratio of correct answers to incorrect answers

Firlakuza [10]

Lesly got 14 answers correctly.

Let the correct answers be C.

Let the incorrect answers be I.

Given the following data:

Total number of questions = 30 questions.

Ratio of C to I = 7 : 8

C to I = 7 + 8 = 15

To find the number of answers she got correctly;

$C = \frac{7}{15}$ × $30$

$C = 7$ × $2$

Correct answers, C = 14 answers

Therefore, Lesly got 14 answers correctly.

13.

Artist 52 [7]

Answer:

5 units

Step-by-step explanation:

An isosceles triangle is a triangle with two legs that have the same length. The perimeter of a triangle is the sum of the lengths of all sides of the triangle. Now taking this into account, we know that:

2L + B = 14 units

Where:

L is the measure of one leg

B is the measure of the base

Since two legs are the same and the base is 1 less, this means the measure of each leg would be:

B = L -1

Now we have two equations:

2L + B = 14 units

B = L- 1

We plug one equation into the other and make 1 equation:

2L + (L-1) = 14 units

Get rid of the parentheses:

2L + L - 1 = 14

Combine like terms:

3L - 1 = 14

Add 1 to both sides of the equation:

3L - 1 + 1 = 14 + 1

3L = 15

Divide both sides by 3:

3L/3 = 15/3

L = 5

So the length of a leg is 5 units

Let's check!

B = L - 1

B = 5 - 1

B = 4

Then we use that to solve for the perimeter:

2L + B

2(5) + 4

10 + 4 = 14

30% of number A is the same as 40% of number B. what could A and B ?

Sunny_sXe [5.5K]

9514 1404 393

Answer:

A = 4, B = 3

Step-by-step explanation:

You require that ...

0.30 × A = 0.40 × B

Then ...

B = (3/4)A . . . . . divide by 0.40

Any pair of numbers that satisfies this equation will be possible values of A and B. One such pair is (A, B) = (4, 3).
