Each person shakes 7 hands, but once you count the handshake between A and B, you don't need to count the handshake between B and A. There are a total of 8*7/2 = 28 handshakes.
Saturday and Sunday: 8 1/4 hours + 6 1/4 hours = 33/4 + 25/4 = 58/4 = 29/2 hours = 14 1/2 hours
A total of 88 1/2 miles = 177/2 miles for both days.
If you would like to know how long does it take him to ride one mile on his bike, you can calculate this using the following steps:
88 1/2 miles ... 14 1/2 hours
1 mile ... x hours = ?
88 1/2 * x = 1 * 14 1/2
177/2 * x = 29/2 /*2
177 * x = 29 /177
x = 29/177 hours
x = 0.16 hours
Result: It takes him 0.16 hours to ride one mile on his bike.
Answer:
B. 1788
Step-by-step explanation:
The volume of solid shaped is expressed in cubic yards. The sides of the shape are multiplied or powered as 3 for the volume determination. Volume is the total space covered by the object. It includes height, length, width. The three dimensional objects volume is found by
length * height * width
The volume for current object is :
12 * 28 * 5
= 1788 cubic yards.
The answer would be B. Only 3.
An object has a line of symmetry when it is cut a certain way and both parts are identical. Only line 3 will give you two identical halves when cut in that way.
Answer:
Yola is 42, Zed is 19
Step-by-step explanation:
I used a system of equations:
y - z = 23
2z + y = 80
Then I graphed them.
