Answer:
22/7
Step-by-step explanation:
Diameter is 2m
we know,
radius= Diameter/2
r = d/2
r = 2/2
r = 1
Now,
area of circle= πr^2
22/7 * 1^2
22/7 ....... answer
Answer:
see explanation
Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
All the equations given are in slope- intercept form
y = 2x + 1 → with m = 2
y =
x - 4 → with m = 
y = x + 1 → with m = 1
y = -
x - 3 → with m = - 
y = 10 + x → y = x + 10 → with m = 1
Thus
y = x + 1 and y = 10 + x are Parallel since both have m = 1
y = 2x + 1 and y = -
x - 3 are Perpendicular since 2 × -
= - 1
1.85x-42.55>100 is the inequality. 42.55 is the amount already raised, 1.85x is number of laps times the money raised by them.
Answer:
E. None of these answers is reasonable.
Step-by-step explanation:
Customary units are inches, feet, yards, and miles.
Since,
1 foot = 0.3048 meters,
⇒ 1 meter =
feet,
17.42 meters =
feet



Now, 1 feet = 12 inches,
⇒
feet =
inches
= 
Hence,
17.42 meters = 
= 57' 232/127''
That is, None of these answers is reasonable.
You can use variables to solve this problem. Lets say that m is men, w is women, and c is children. m+w+c=266
four times as many men as children in ‘math words’ would be 4c=m
twice as many women as children would be 2c=w
what we can do now is plug those in to make everything easier with one variable
4c+2c+c=266
7c=266
c=38 now we have how many children, and we need to plug it back into what we have for women and men.
4c=m 4(38)=m m=152
2c=w 2(38)=w w=76
152 men, 76 women, and 38 children
