What's up?
let's implement these numbers into the problem first.
3•3 + 1/4 4^2
let's solve what we can
9 + 1/4 • 16
9 + 4 = 13
Answer:
1995 => 22°
2005 => 36°
Step-by-step explanation:
Central angle of the sector representing nuclear energy in 1995 = percentage of nuclear energy in 1995 ÷ 100 × 360°
Nuclear energy is approximately 6% (rounded to whole number) in 1995.
Central angle = 
Central angle representing nuclear energy in 1995 ≈ 22° (nearest whole number).
Central angle of the sector representing nuclear energy in 2005 = percentage of nuclear energy in 2005 ÷ 100 × 360°
Nuclear energy is approximately 10% (rounded to whole number) in 1995.
Central angle = 
Central angle representing nuclear energy in 2005 = 36°.
Answer:
x = 28/3
Step-by-step explanation:
We can solve this problem by using similar triangles:
Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.
Now we can set up ratios and solve:
13/7 = (x+8)/x
multiply both sides by x:
13x/7 = x+8
Multiply both sides by 7:
13x = 7x + 56
move the 7x over and divide by 6:
6x = 56
x = 28/3
Answer
9/20
Step-by-step explanation:
This is a probabilty, problem
firstly, let us bring out the sample space and size
the sample space is
9 apples,
5 bananas,
1 orange, and
5 peaches
The sample size is (9+5+1+5)= 20
The probability of picking a banana is
Pr(banana) =5/20
=1/4
The probability of picking an apple
Pr(apple) = 9/20
The probability of picking up a banana and an apple with replacement is
=1/4+9/20
=9/80
