Answer:
it should be 47
Step-by-step explanation:
Length x width equals area of rectangle. 301/2÷61/2=5
the width of the rectangle equals 5 inches.
It would take 110 seconds or a minute and 40 seconds. 400 divided by 50 = 4...... 27.5 multiplied by 4 equals 110; therefore, the answer is mike would swim 400 meters in 110 seconds.
To solve use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
14 + 18 ÷ 2 x 18 - 7
Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be division first then multiplication.
NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression
Division
14 + 18 ÷ 2 x 18 - 7
18 ÷ 2 = 9
14 + 9 × 18 - 7
Multiplication
14 + 9 × 18 - 7
9 × 18 = 162
14 + 162 - 7
Addition
14 + 162 - 7
14 + 162 = 176
Subtraction
176 - 7
= 169
