Answer: $4.95
20 • .30 = 6
20 - 6 = 14
14 • .075 = 1.05
14 + 1.05 = 15.05
20 - 15.05 = 4.95
The answer is 0.625 because 1 mm=0.001 meter.
Steps:
10x50=500
500x1.25=625
Convert from mm to meters.
Answer:
1) 8.9 cm
2) 44.5 cm^2
Step-by-step explanation:
a) we want to calculate the length of the arc
Mathematically, we use the formula for the length of an arc
That will be ;
theta/360 * 2 * pi * r
theta = central angle = 51
r is radius = 10 cm
so we have ;
51/360 * 2 * 22/7 * 10 = 8.9 cm
2) The area of the sector is;
theta/360 * pi * r^2
51/360 * 22/7 * 10^2
= 44.5 cm^2
Answer:
SQUARE= 108 blocks
CIRCLE= 97.97
# OF BUNDLES= 2.05, 3
Step-by-step explanation:
square- find perimeter
- 22.5 x 4= 90ft
- 90ft/10inches
- convert 90 ft to inches> 90 x 12= 1080/10= 108
circle-
- find the circumference= c=2piR
- 2x3.14x13=81.64
- 81.64ft to in = 979.68/10
- =97 rounded
number of bundles = 205/100 =2.05, so 3
Answer:
4
Step-by-step explanation:
The length of CD will be twice the distance from the midpoint to the endpoint
To calculate the length use the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (8, 3)
d = 2 × 
= 2 × 
= 2 × 
= 2 × 
= 2 × 2 = 4 ← exact length
