Answer:
70.4metres
Step-by-step explanation:
Wheel Diameter = 0.7m
Wheel Radius; 0.7m / 2 = 0.35m
For one rotation of the wheel, the distance travelled = circumference of the wheel.
Circumference = 2 x pi x radius
= 2 × π × r
= 2 × π × 0.35
= 2.1991148575 m
Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions
Distance travelled with 32 full revolutions of the wheel = 32 x 2.1991148575 m =
Distance in meters = 70.37167544m
Approximately = 70.4m
Therefore, Elaine managed to cycle 70.4metres
Answer:
≈ 77 cm²
Step-by-step explanation:
The area of the shaded portion is calculated as
area of outer sector - area of inner sector
= (πR² - π r²) × ( R is the outer radius, r is the inner radius )
= (π × 14² - π × 7² ) ×
= (196π - 49π ) ÷ 6
= 147π ÷ 6
≈ 77 cm² ( nearest whole number )
<span>-5m+17=52
Subtract 17 from both sides
-5m= 35
Divide -5 on both sides
Final Answer: m= -7</span>
Answer:
$3.00 is the constant
Step-by-step explanation:
let x be the mile driven then
total charge=$3.00+[x($0.30)]
Answer:
18.9
Step-by-step explanation:
Start with parentheses.
4/5 + 3/5 = 7/5
Simplify 7/5, 7/5 = 1 2/5
Next numbers.
3.5 x 5 = 17.5
Add.
17.5 + 1 2/5 = 18.9
