Answer:
area = 301.44 in²
Step-by-step explanation:
area of top and bottom = π4² = 50.24 each, 100.48 in² for both
circumference = π2r = π2(4) = 25.12
25.12 x 8 = 200.96 in² area of side
100.48 + 200.96 = 301.44 in²
Answer: there are 50 humans and 24 horses.
Step-by-step explanation:
Let x represent the number of humans in the horse racing area.
Let y represent the number of horses in the horse racing area.
He counted 74 heads. A human has one head and a horse also has one head. It means that
x + y = 74
He counted 196 legs. A human has 2 legs and a horse has 4 legs. It means that
2x + 4y = 196 - - - - - - - -- - -1
Substituting x = 74 - y into equation 1, it becomes
2(74 - y) + 4y = 196
148 - 2y + 4y = 196
- 2y + 4y = 196 - 148
2y = 48
y = 48/2 = 24
x = 74 - y = 74 - 24
x = 50
Answer:
6x+2
Step-by-step explanation:
The perimeter is all of the sides added together.
We know that in a rectangle, sides that are parallel to each other are the same.
So, to find the expression that represents the perimeter, you have to multiply 2x+1 by 2 and x by 2 and add both of those together.
(2*(2x+1))+(2*(x))
(4x+2)+(2x)
4x+2+2x
6x+2

Multiplicative Inverse of rational number:
When we multiply a rational number and its multiplicative inverse, we get 1
Now,multiply this with (3/-17)
So, -5 2/3 is the multiplicatice inverse of 3/-17
