Answer:
so the first awnser is 90 and i am verry sorry but i do not know how to do the second one and the third does not have enogh information
Step-by-step explanation:
1. so first 12 inches is one foot, multiply 12 by 60 to get 720 now because it says that 1 inch is 8 feet and 720 is how manny inches it is so 720 divided by 8 is 90.

➷ First calculate how many counters are 'not white'
12 - 7 = 5
We have 5 counters that are 'not white'
The probability of taking a white counter the first time is 7/12
For the next pick, there would be 1 less of the total counters as it is not being replaced
The probability of then taking a 'not white' counter is 5/11
The other way you could still get one white counter is:
The first counter (non white) probability would be 5/12
The second counter (white) probability would be 7/11
Multiply these values:
7/12 x 5/11 = 35/132
5/12 x 7/11 = 35/132
Add these two values together:
35/132 + 35/132 = 70/132
Your answer is 70/132

Answer:
It is a factor
Step-by-step explanation:
[x³ -7x² + 8x + 16] ÷ (x + 1)
[x³ + x² - 8x² - 8x + 16x + 16] ÷ (x + 1)
[x²(x + 1) - 8x(x + 1) + 16(x + 1)] ÷ (x + 1)
x² - 8x + 16 and tye remainder is 0.
So, yes (x + 1) is a factor
Answer:
x²+y²-4x-6y+12.75=0
Step-by-step explanation:
The equation is given by (x-h)²+(y-k)²=r²
center is (2,3), so h=2, k=3,r=0.5
equation is given by;
(x-2)²+(y-3)²=0.5²
Expand
x(x-2)-2(x-2)+y(y-3)-3(y-3)=0.5²
4-2x-2x+x²+9-3y-3y+y²=0.25
4-4x+x²+9-6y+y²=0.25
x²-4x+13+y²-6y=0.25
x²-4x+y²-6y+13=0.25
x²-4x+y²-6y+12.75=0
x²+y²-4x-6y+12.75=0
Answer: answer is E
Step-by-step explanation: because it slope is -6(x) and intercept is (+)9
