Answer:
QR = 5
Step-by-step explanation:
Since the parallelograms are similar, then the ratios of corresponding sides are equal, that is
= 
, then
= 
( cross- multiply )
9QR = 45 ( divide both sides by 9 )
QR = 5
Answer:
- Circumference = 69.14cm
- Area = 380.29cm²
Step-by-step explanation:
Circumference.
Circumference of a circle is calculated by the formula:
= Pie * diameter
= π * diameter
= 22/7 * 22
= 69.14 cm
Area
Area of circle:
= Pie * radius ²
Radius = diameter/2
= 22/2
= 11 cm
Area = 22/7 * 11²
= 22/7 * 121
= 380.29 cm²
Answer:
False
Step-by-step explanation:
The lowest point is at 11.
Answer:
r=0
Step-by-step explanation:
1) Place point (2, 3) on graph.
2) Use the slope of -1 to go left -1 and go down -1
3) Until you get to x value of -1
In this question, you're solving for x.
Solve for x:
2(4 - 8x) + 5(2x - 3) = 20 - 5x
Use the distributive property:
8 - 16x + 5(2x - 3) = 20 - 5x
8 - 16x + 10x - 15 = 20 - 5x
Combine like terms:
8 - 16x + 10x - 15 = 20 - 5x
8 - 6x - 15= 20 - 5x
-6x - 7 = 20 - 5x
Add 5x to both sides
-x - 7 = 20
Add 7 to both sides
-x = 27
Divide both sides by -1
x = -27
Answer:
x = -27
