Luther evaluated 2³ as 9 and Wade evaluated 3² as 9. Are both students correct? Explain why or why not.

Answers

Answer 1

Answer:

No, Wade is correct  Luther is incorrect

Step-by-step explanation:

3^2 =3*3 which is 9

2^3 = 2*2*2 which is 8

The two powers are not equal. Wade is correct, but Luther misinterpreted 2 to the power of 3 as 2 factors of 3. He switched the base and exponent. Luther’s value should be 2 times 2 times 2, which is 8.

Hope I helped

Brainliest plz

Answer 2
Wade is correct but luther is not. This is because when your multiplying exponents, you multiply the coefficient (the bug number) but the exponent (the little number). So, for 3^2 it would look like 3x3=9, so wade is correct! But for Luther, 2^3 would like like 2x2x2. So 2x2 we know equals 4 and then 4x2 equals 8. Which isn’t 9, so Wade is right and Luther is wrong

Carlos took a test and made a 50. On the next test, he made 75. What is the percentage of change between the two test scores?

A. 150% increase
B. 150% decrease
C. 50% decrease
D. 50% increase

Answers

Answer:

D

because if you increase by 50%, you get half of 50, which is added on ecause its an increase, therefore you should be left with 75%

D. 50% increase! 50% of 75 is 25, and 25+50=75%

How to find out the answer to the problem,
-3/4 ÷ -1/8=

Answers

Answer:

6

Step-by-step explanation:

Dividing a negative by a negative will get you a positive result, so we can treat these fractions as positive numbers. To divide fractions, we take the reciprocal of the fraction we're dividing by and it'll be multiplied by the first fraction. To multiply fractions, we multiply numerator with numerator and denominator with denominator.

-3/4 ÷ -1/8 = 3/4 ÷ 1/8 = 3/4 * 8/1 = 24/4 = 6
