Try using a theory ask your teacher if a ruler can be used
Answer:
Step-by-step explanation:
4 over 5 = 4/5
First, multiply 20 to both numerator and denominator:
(4/5)(20/20) = 80/100
Next, change the fraction into a decimal. move the decimal sign to the left two place values (and drop the denominator)
80/100 = 0.80
Next, to change the decimal to a percentage, move the decimal point to the right two place value and add the % sign.
0.80 = 80%
80% is your answer

Table of the graph:
x: <em>
</em>
1 2 3
y: 5 25 125
Average Rate of Change =
Section A = 25-5/2-1 =20/1 =20
Section B = 125 - 25/ 3-2 = 100/1 = 100
So, Section B is 5 times greater than A.
Section B is greater because the slope of two points is greater than points in Section A.
Answer: |55.75 - (-15.8)|
Step-by-step explanation:
This is the answer that they have for edmentum but you can just copy it :)
From the diagram;
1. Angle 2 = ADB+BDH
= arcAB/2 +90
= 34 +90
= 124°
2. Angle 4= 90°,
Reason ; the angle between a tangent and a radius is equal to 90. A tangent is a line that touches the circumference of a circle once even if prolonged.
3. Angle 5 = 90 -BDC (note the acr subtends twice the angle it subtends on the circumference to the center.
= 90-arc BC/2
= 90-36
= 54°
4. Angle 6 = BFD
= 180-ADB-FBD
= 180-AB/2-DE/2
But DE = 180 -121 = 59
Therefore, BFD = 180 -34-29.5
= 116.5°
5. Angle 1 = 180- BFD (angles on a straight line add up to 180°)
= 180- 116.5
= 63.5°
6. Angle 3 = 180 -(ADB+BFD)
= 180 -(34 +116.5)
= 180- 150.5
= 29.5°
similarly angle 3 = DE/2 = 59/2 = 29.5°
7. Angle 8= 90, because BD is diameter;
angles subtended by a diameter to the circumference is always a right angle (90°)
8.Angle 7 = BE
but BE= AB+AE
= 68+ 53
= 121°
