In the middle school debate club, 30%
of the members are in sixth grade. If
there are 12 sixth graders in the debate
club, how many total members are
there?
a. 30
b. 36
c. 38
d. 40
Answer:
40
Step-by-step explanation:
I used a calculator tbh but all you have to do is multiply the number by the percentage. 30% * 40 is 12.
There are total 40 members in the middle school, option (d) is correct
What is percentage?Percentage is a measurement to find the value of a given number out of hundred.
Given that,
Percentage of the members present in 6th grade = 30%
Also, the number of the sixth grade members = 12
According to the condition,
30% = 12
1% = 12/30
Total members are 100%,
So, 100% = 40
Total number of members is 40 in the middle school.

The digit at the tens place of a two digit number is three times the digit at ones place . If the sum of this number and the number formed by reversing it's digits is 88 . Find the number .
Digit at the ten's place is three times the digit at ones place.
The sum of the number and the number formed by reversing the digits = 88
Find:the number
Solution:Let the digit at ten's place be x and digit at one's place be y.
The number = 10x + y or xy
Digit at the ten's place is three times the digit at ones place.
→ x = 3y -- equation (1)
Also,
The sum of the number and the number formed by reversing the digits = 88
Number formed by reversing the digits = 10y + x
Hence,
→ 10x + y + 10y + x = 88
→ 11x + 11y = 88
→ 11(x + y) = 88
→ x + y = 88/11
Substitute the value of x from equation (1).
→ 3y + y = 8
→ 4y = 8
→ y = 8/4
→ y = 2
Putting the value of y in equation (1) we get,
→ x = 3 * 2
→ x = 6
The number = xy = 62.
Therefore, the required two digit number is 62.
I hope it will help you.

An architect needs two support beams for a building. One beam has a length of 2 (square foot) 3 meters. Another has a length of 3 (square foot) 2 meters. Explain how can you find which beam is longer.
Answer:
First beam is longer
Step-by-step explanation:
Convert all units to meters
2 square foot = 0.1858 square meters=0.431 meter
First beam's length = 0.431 +3 =3.431 meters
3 square foot = 0.2787 square meters=0.528 meter
Second beam's length = 0.528 +2 = 2.528 meters
First beam is longer

Lin read for x minutes, and Elena read for 5/8 more than that. Write an expression for the number of minutes Elena read. Only use decimals in your expression.
Answer: The expression for the number of minutes Elena read. = x+0.625
Step-by-step explanation:
Given: Lin read for x minutes, and Elena read for 5/8 more than that.
Then, Elena reads = [tex]x+\dfrac58[/tex] minutes
Also, [tex]\dfrac58=0.625[/tex] [divide 5 by 8]
So expression becomes, [tex]x+0.625[/tex]
Hence, the expression for the number of minutes Elena read. = x+0.625

Answer:
The method that will not give the correct number of inches is:
Multiply 2 1/2×3, and then add 34.
Step-by-step explanation:
A small plant is 2 1/2 inches tall. How tall will it be in 3 weeks if it grows 34 inch each week?
For the first week
2 1/2 inches + 34 inches
For 3 weeks
= 2 1/2 inches + 3(34) inches
= 2 1/2 inches + (34 + 34 + 34)inches
= 2 1/2 inches + 102 inches
= 104 1/2 inches
The height of the small plant after 3 weeks
= 104 1/2 inches
Which method will NOT give the correct number of inches?
The method that will not give the correct number of inches is:
Multiply 2 1/2×3, and then add 34.
