Its D. they are equidistant from the center of the circle , just took the test and that was the answer on apex
1) You must add 4 to each side to complete the square.
2) You must add 16 to each side to complete the square.
3) You must add 27 to each side to complete the square.
Explanation:
1) x²-4x=0
To find the number that we add to both sides, we look at b, the cofficient of x. It is -4. We divide it by 2 and square it; -4/2 = -2; (-2)² = 4. This is the value that we add to both sides.
2) x²-8x=6
-8/2 = -4; (-4)²=16
We add 16 to each side to complete the square.
3) 3x²+18x=24
First we can factor a 3 out of the left side:
3(x²+6x) = 24
Our b value is now 6. 6/2 = 3; 3²=9. The 9 would, however, go in the parentheses, so it would be multiplied by 3, which makes 27; this means we would add 27 to both sides.
we know that
The unit rate is $0.65 per foot
so
To find out the cost, multiply the unit rate by the length of the rope
so
0.65*(10.8)=$7.02
therefore
<h2>The cost is $7.02</h2>
Answer:
7r³ - 3r² + 20r
Step-by-step explanation:
(9r³ + 5r² + 11r) + (-2r³ + 9r - 8r²)
You can get rid of the parentheses since there is nothing to distribute.
9r³ + 5r² + 11r - 2r³ + 9r - 8r²
Combine like factors.
7r³ - 3r² + 20r
The group that had the highest percentage of students that like Sports is group B.
The group that had the less percentage of students that like English is group A.
the percentage of students like Math in group A is 30% and 10% in group B
<h3>What are the percentages?</h3>
A pie chart is a graph that displays information in a circle. The circle is divided into slices which represent a numerical proportion. The sum of angles in a pie chart is 360 degrees
Percentage of students that like sports in:
- Group A = [20 / (20 + 15 + 5 + 10)] x 100 = 40%
- Group B = [22 / (5 + 4 + 9 + 22)] x 100 = 55%
Percentage of students that like English in:
- Group A = [5 / (20 + 15 + 5 + 10)] x 100 = 10%
- Group B = [5 / (5 + 4 + 9 + 22)] x 100 = 22.5%
Percentage of students that like Maths in:
Group A = [15 / (20 + 15 + 5 + 10)] x 100 = 30%
- Group B = [4 / (5 + 4 + 9 + 22)] x 100 = 10%
