Answer:
It is f(x), y or the "output".
Step-by-step explanation:
Using PEMDAS...
<span>4 x 4 + 4 x 4 + 4 - 4 x 4 =
(16) + (16) + 4 - (16) =
36 - 16 = 20
Your answer is 20, not 320.
You must multiply before you add and subtract</span>
Using proportions, it is found that he must have fewer at bats than Player A, as the batting average is inverse proportional to the number of at bats, hence you friend is incorrect.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The batting average is given by the division of the number of hits by the number of at bats. Player B has fewer hits but a greater batting average, which means that he must have fewer at bats than Player A, as the batting average is inverse proportional to the number of at bats, hence you friend is incorrect.

Hello!
ANSWER:
36 students have a dog as a pet, and 30 students have a cat as a pet.
EXPLANATION:
Let's quickly convert these fractions to decimals by dividing their numerators by their denominators.
4 ÷ 5 = 0.8
2 ÷ 3 = 0.6666666667
Now, multiply the decimal forms by the number of students in Mrs. Hu's class.
0.8 × 45 = 36
0.(6)7 × 45 = 30
Answer:
136 cm^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) *h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 12+22) *8
= 1/2 (34) * 8
= 136 cm^2
