perimeter = Answer:
Step-by-step explanation:
5. Perimeter of semi circle = r(pi+2)
Given diameter=17m; r=17/2
Perimeter = (17/2)(pi+2)
6. Given diameter = 10.5
Perimeter = (10.5/2)(pi+2)
Answer:
when we add two negative numbers the result will always be a negative number, on adding negative numbers the direction of the move will always be to the left side
hope this helps!
Answer:
Step-by-step explanation:
Equation
L = a + (n - 1)*d
Givens
L = 55
a = 13
n =8
Solution
55 = 13 + (8 - 1)*d Combine
55 = 13 + 7d Subtract 13 from both sides
55 - 13 = 7d
42 = 7d Divide by 7
d = 6
Answer:
2
Step-by-step explanation:
Fill in each function's argument and do the arithmetic.
Answer:
tall candles = 39
Short candles = 52
Step-by-step explanation:
let tall candles be x
and short candles be y
No. Of candles sold = x + y =91
Money made from candles will be equal to = 8x + 5y = $572
These both are simultaneous linear equations.
x + y =91 ( multiply by 5)
5x + 5y = 455
8x + 5y = $572
Subtract them:
-3x = -117
x = -117/3
x = 39
put value of x in
x + y = 91
39 + y = 91
y = 91 - 39
y = 52
x shows tall candles so they are 39
y shows short candles so they are 52
