Answer:
200.96 square feet
Step-by-step explanation:
The amount of fencing Scott will need to buy can be gotten by calculating the area of the circular rock garden .
Area of a circle is given by
Pi r^2
Where
r = radius
Given diameter of 16 feet
r = diameter/2
= 16/2
= 8 feet
Pi = 3.14
Therefore,
Area = 3.14 x 8^2
= 3.14 x 8 x 8
= 200.96 square feet
The amount of fencing Scott will need to buy is 200.96square feet
Answer:
CNBD
Step-by-step explanation:
From the diagram, we can see that:
Then by Alternate Interior Angles:
From vertical angles, we also know that:
This is all we can gather from the given image. Knowing only three pairs of angles cannot prove congruence, as proving congruence requires at least one side.
Congruence cannot be determined.
Type A cost $5.75 per pound
Type B cost $4.25 per pound.
Set up 2 equations:
A. + B = 174 pounds
5.75A + 4.25B = 880.50
Rewrite the first equation as A= 174 - B
Replace A in the second equation:
5.75(174-B) + 4.25B= 880.50
Use distributive property:
1000.50 - 5.75B + 4.25B = 880.50
Combine like terms:
1000.50 - 1.5B = 880.50
Subtract 1000.50 from both sides:
-1.5B = -120
Divide both sides by -1.5:
B = -120 / -1.5
B = 80
They used 80 pounds of type B
Subtract B from the total used to find type A:
174 - 80 = 94
They used 94 pounds of type A
Due to the fact that the question states there is a 65% chance the bus will be full, that is a very high probability. Therefore, there is only a 35% chance it wont be full. Or you can say it in fractional form: 65/100 chance of it being full, and a 35/100 chance of it being less than full.<span />
She simplified it wrong because you're only supposed to simplify it with the same numbers. For example: simplify 2/4. You divide it by 2/2. You do the same and it will be correct.
