Jay should have applied division operation first, then addition operation.
The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Given:
We have an expression,
3 × (3 + 12 ÷ 3) - 4.
In order to solve the problem,
we can use PEMDAS.
First, we solve parenthesis,
and division.
3 × (3 + 4) - 4.
Now,
3 × 7 - 4.
Now, multiplication,
21 - 4.
= 17
Therefore, the solution is 17.

#1 What is the volume of a pyramid with base area B = 6 ft2 and height h = 13 ft? A. 26 ft3 B. 39 ft3 C. 52 ft3 D. 78 ft3 #2 The base of a square pyramid has a side length of 6 inches. The height of the pyramid is 12 inches. What is the volume of the pyramid? A. 144 in3 B. 36 in3 C. 72 in3 D. 108 in3
Answer:
1). Option A is correct.
2). option A is correct.
Step-by-step explanation:
1).
Given : Area of Base = 6 ft.² and height, h = 13 ft.
Volume of pyramid =
=
= 2 × 13 = 26 ft.³
Therefore, Option A is correct.
2).
Side of square of base = 6 inches.
Height of pyramid = 12 inches
Base Area = Area of Square
= side × side = 6 × 6 = 36 inches²
Volume of pyramid =
=
= 36 × 4 = 144 inches³
Therefore, Option A is correct.
Answer:
It will take 13 years until Ishaan is only 5 times as old as William.
A.
–27
B.
27
The absolute value of -27 is 27.
The absolute value of a number is its distance from zero on the number line, regardless of whether the number is positive or negative.
In the case of -27, the absolute value is calculated by removing the negative sign, resulting in a positive value.
Therefore, the absolute value of -27 is 27.

I think it is 1/216
80* 4/5
Cross out 80 and 5
You can divide by 5 for both of the numbers
80/5=16
5/5=1
16*4= 64
Answer is 64
