Answer:
Step-by-step explanation:
The scale factor = 1 : 20
<u>The area is the product of two dimensions, so the area of the model part to actual part is:</u>
<u>If the actual plane has wing area of 400 ft², then the model will have wing area:</u>
Given: w²+9=6w [0, 3, 6, 9]
We need to substitute each number for w and find which works
Sub Zero: 0²+9=6×0
Simplify: 9=0. 9 does not equal 0, so it is not 0
Sub Three: 3²+9=6×3
Simplify: 9+9=18
Addition: 18=18
The statement 18=18 is true, therefore we have our answer.
Answer: The second option is correct. 3 would be the correct number to substitute to make the equation correct.
429 ÷ 39= 11
11 ÷ 2= 5.5 (5 1/2)
It takes 5 1/2 weeks to produce 429 wetsuits
Answer:
Sierra's team has a greater percent of left-handed batters.
25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.
Step-by-step explanation:
Sierra: 7/28 = 1/4
1/4 written as a percentage is 25%
Aubrey: 5/25 = 1/5
1/5 written as a percentage is 20%
25% is greater than 20%, so Sierra's team has a greater percent of left-handed batters.
25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.
Hope this helps ;)
