Answer:
50.6 cm
Step-by-step explanation:
We can use similar triangles and proportions to solve. Put the smaller triangle side over the larger triangle side.
x 46.2-14 (This is the length of the short side of the triangle)
--------- = -------------
72.6 46.2
Using cross products
46.2 *x = (46.2-14) *72.6
46.2 *x = (32.2) *72.6
46.2 *x = (32.2) *72.6
46.2x =2337.72
Divide each side by 46.2
46.2/46.2 *x = 2337.72/46.2
x = 50.6

Answer:
Step-by-step explanation:
distance = rate * time
rate = distance / time
= 2/3 mile divided by 1/2 hour
= 2/3 * 2/1 = 4/3 mph = 1 and 1/3 mph
His speed is 4/3 mph = 1 and 1/3 mph = 1.3 mph
So
1 mile = (4/3 mph) * TIME
Solving for Time T, it will take him t = 3/4 <--- the RECIPROCAL
and 3/4 hour = 45 minutes
Jack walks 1 mile in 45 minutes = 3/4 hour
Answer:
2 19/21, 61/21
Step-by-step explanation:
First, lets make the denimonators, "3 and 7" common. 3 and 7 are prime numbers, so the common denonminator is "21".
For 7/3, multiply by "7/7" and for 4/7 multiply by "3/3".
49/21 + 12/21
Add.
61/21
61 is a prime number so this answer will be your final answer.
(unless you have to put it as a mixed number which would be 2 19/21)
I feel like it is B hope this helps
