Answer:
answer: 560
Step-by-step explanation:
Multiply 5 by 112 so 112 × 5 = 560 So 112 is 20% of 560
It's an isosceles triangle so that you bottom angles are 71 add those then subtract whatever the sum of 71 + 71 is minus 180. and there's the third angle
Answer: 1.83
Step-by-step explanation:
Z = (x - mean) / standard deviation
= (97-75) / 12
= 22/12 = 11/6 = 1.83
He would have to take out at least 16 coins.
Taking any less could result in having fewer quarters since even 15 could result in <span>12 dimes and 3 quarters. This way it will always be at least 4 quarters.</span>
Answer:
The arc length of a circle is 3.14 m or 1π m
Step-by-step explanation:
First of all we have to calculate the circumference of the circle and then extract the portion that corresponds to 90°
To solve this exercise we need to use the circumference formula of a circle:
c = circumference
r = radius = 2m
π = 3.14
c = 2π * r
we replace the known values
c = 2 * 3.14 * 2m
c = 12.56m
As we know a circle is represented with 360 ° and they tell us that the angle is 90 °, so we have to know the relationship with respect to the total
90° / 360° = 1/4
Now we multiply this number by the circumference and we will obtain the length of the arc
12.56m * 1/4 = 3.14
The arc length of a circle is 3.14 m or 1π m
