Answer:
C. 4 weeks
Step-by-step explanation:
Trish and Aria are walking to raise money for the school library. Trish has walked 38 miles and walks 10 miles each week. Aria has walked 30 miles and walks 12 miles each week
After how many weeks will Trish and Aria have walked the same number of miles? A. 2 weeks B. 3 weeks C. 4 weeks D. 5 weeks
Trish = 38 + 10x
Aria = 30 + 12x
Where,
x = number of weeks
After how many weeks will Trish and Aria have walked the same number of miles?
Equate both equations
38 + 10x = 30 + 12x
38 - 30 = 12x - 10x
8 = 2x
x = 8/2
x = 4 weeks
Answer:
57.1mm^2
Step-by-step explanation:
4*4=16
16/2=8mm^2 cross section
(4*3) + (4*3) + (5.7*3) = 41.1mm
8*2=16
41.1+16=57.1mm^2
Answer:
~2000 lbs
Step-by-step explanation:
Set up a proportion:

Answer: See explanation
Step-by-step explanation:
The dimensions of the first drawing will be 1/3 the dimensions of the leaf and the dimension of the oak leaf is 5 1/2 inches. Therefore, the dimensions of the 1st leaf:
= 1/3 × 5 1/2
= 1/3 × 11/2
= 11/6
= 1 5/6 inches
This is less than 5 1/2 inches
The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. This will be:
= 2 1/2 × 5 1/2
= 5/2 × 11/2
= 55/4
= 13 3/4 inches
Thus is greater than 5 1/2 inches
