Answer:
The correct option is;
C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2
Step-by-step explanation:
The area of the square frame is the area of the inner square subtracted from the area of the outer square
Which gives;
52.2² - 47.8² = 440
Therefore;
Option A. 52.2² - 47.8² is a correct way of finding the area of the square frame
Option B. 2 × ((52.2×2.2) + (47.8×2.2)) = 440, is a correct way of finding the area of the square frame
Option C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2 = 880, is not a correct way of finding the area of the square frame
The error is the thickness is 2.2 not 4.4
Option D. 100×(52.2 - 47.8) = (52.2 + 47.8) × (52.2 - 47.8) = 52.2² - 47.8² = 440, is a correct way of finding the area of the square frame
Answer:
26 wins , 14 ties
Step-by-step explanation:
Given: Hockey teams receive 
points when they win and 
point when they tie. One season, a team won a championship with 
points. They won 
more games than they tied.
To Find: How many wins and how many ties did the team have.
Solution:
let the number of wins hockey team have 
let the number of ties hockey team have 
Now,
Hockey teams receive points when they win and point when they tie.
They won more games than they tied
Solving both equations we get
Hence, the hockey team have 
wins and 
ties.
Answer:
x = 37.5
Step-by-step explanation:
By Basic Proportionality Theorem:
Answer:
739.47
Step-by-step explanation:
height - h, radius -r
V=hπ²r=5×3.14²×15=739.47
26' wheel @ 90 rpms = 2,340 inches / min (26 x 90)
2,340 inches / min = 140,400 inches / hour (2,340 x 60)
140,400 inches / hour = 11,700 feet / hour (140,400 / 12)
11,700 feet / hour = approx. 2.216 miles / hour (11,700 / 5,280)
