Answer:
Step-by-step explanation:
Radius = r = 9 cm
Angle = θ = 200° = 3.5 radians
Now,
Area = 1/2 (9)²(3.5)
Area = 1/2 (81)(3.5)
Area = 282.7 / 2
Area of sector = 141.4 cm²
Bottom right! You are correct. :)
Answer:
8 baskets
Step-by-step explanation:
Well, we can simply divide each number by the amount of vegetables are needed.
6/6=1. We only need 1 basket for tomatoes.
21/3=7. We need 7 baskets for potatoes.
7+1=8 We need 8 total baskets.
Hope this helps! :D
Answer:
The value of the investment by the end of the month is $59.89.
Percent loss = 20% to the nearest tenth
Step-by-step explanation:
At the end of the month, there was a loss of $13.53 from the $73.42 investment at the beginning of the month.
Value in Dollars = $73.42 - $13.53
= $59.89
The value of the investment by the end of the month is $59.89.
PERCENTAGE LOSS =
(CP - SP / CP ) * 100
= ($73.42 - $59.89 / $73.42) * 100
= ($13.53 / $73.42) * 100
= 0.184 * 100
= 18.43%
= 20% to the nearest tenth
Enjoy! Maths is fun
For this question, I would first see what one child is equal toby divide the children by the percentage.
15÷3= 5
Each child is worth 5%. If you know each child is worth 5%, and the total number of students are 100%, then you can divide.
100÷5= 20
There are 20 students in the class. To make sure our answer is right, we can check to see if 3 students are 15 percent.
3÷20= .15×100= 15
So yes, there are 20 students in the class.
