Answer:
500 times
Step-by-step explanation:
They breathe 20 times per minute for 25 minutes
20(times per minute) x 25(minutes) = 500
Answer: 2/3
Simplifying fractions: Reducing the fraction to its lowest term by finding the greatest common factor and dividing both the numerator and denominator by the GCF.
GCF: The greatest common factor is integer divisible by both numbers. This number will evenly divide into both the numerator and denominator in this case.
Simplest term: The smallest possible number that cannot be reduced further while remaining as an integer.
Factors of numerator (6): 1, 2, 3, 6
Factors of Denominator (9): 1, 3, 9
- both numbers have a common factor of 3 which is the greatest
Steps to Calculate:
1. Find the GCF
2. Divide numerator and denominator by GCF
6/3 = 2
9/3 = 3
Therefore, the lowest term would be 2/3
Answer:
C
Step-by-step explanation:
Here, we are told that the school is trying to plant a garden which is trapezoidal in shape and we want to calculate the area of this said garden.
Mathematically, the area of the garden can be calculated using the formula;
A = 1/2 (a + b)h
here in this question, a is the value on the right hand side which is 75 ft, b is the value on the left hand side which is 85ft while h is the value on the bottom
which is 102 ft
Inserting these values into the equation, we have:
A = 1/2( 75 + 85) * 102
A = 1/2 * 160 * 102
A = 8,160 ft^2
C.
3(x+8)=9
Always make sure u do PEMDAS so since the number that Amy picked is unknown we will label it X. Next step was x added to 8 which will look like this x+8 but wants the sum multiplied by 3 so since we don't know the answer we will close it in parenthesis and multiply it by 3 which will look like 3(x+8) and lastly add the equal sign and the number 9.
