Answer:
P(A and 2) = 1/12, P(D and 1) = 1/8, P(A and not 2) = 1/6
Step-by-step explanation:
P(A and 2)
There is a 1/4 chance that you hit a when you spin the spinner. There is a 2/6 chance that you hit two when you spin the spinner. 1/4*2/6 = 2/24=1/12
P(D and 1)
There is a 1/4 chance that you hit d when you spin the spinner. There is a 3/6 chance that you hit one when you spin the spinner. 1/4*3/6=3/24=1/8.
P(A and not 2)
There is a 1/4 chance that you hit a when you spin the spinner. There is a 4/6 chance that you hit anything but two in the second spinner. 1/4*4/6=4/24=1/6

A 15 ft long cable is connected from a hook to the top of a pole that has an unknown height. The distance from the hook to the base of the pole is 3 ft shorter than the height of the pole.
a. What can you use to find the height of the pole?
b. Write and solve a quadratic equation to find the height of the pole.
c. How far is the hook from the base of the pole?
a. What can you use to find the height of the pole?
solution: We can use Pythagoras theorem to find the height of the pole.
b. Write and solve a quadratic equation to find the height of the pole.
solution:
a² + b² = c²

Which shape has parallel side i-Ready
I never get help in this app but can someone at least solve this problem
Answer:
21
Step-by-step explanation:
If the angles are supplementary, that means they add up to 180 degrees.
That means if we subtract 75 from 180, we get 105.
If we divide 105 by 5, we get 21.
That means 21 * 5 + 75 = 180
or
5(21) + 75 = 180
Hope this helps!

A. 5/100
B. 8/100
C. 63/100
D. 108/100
WILL GIVE BRAINLIEST
Answer: B. 8/100
Let's give 5/10 a denominator of 100 since 58/100 does, so they have common denominators:
5/10 * 10 = 50/100
Now, we can subtract 50/100 from 58/100 to find the unknown fraction:
58/100 - 50/100 = 8/100
This gives us an answer of,
B. 8/100

Help me with this pls i dont understand
Answer:
Slope is 6 and Y intercept is 4.. You can look the image above.
solve each system by substitution.
y=3x-5
y=-6x-5
????
y=8x-9
y=-8x+7
???
-x+6y=21
y=-5x+12
?????
Given:
y = 3x - 5y = -6x - 5Multiplying y = 3x - 5 by 2:
=> 2(y = 3x - 5)y = -6x - 5
=> 2y = 6x - 10y = -6x - 5
Adding both equations:
=> 3y = -15Dividing 3 both sides:
=> y = -5Substitute the value of y into any equation.
y = -6x - 5=> -5 = -6x - 5=> 0 = -6xDivide -6 both sides.
=> x = 0/-6 = 0Solution (2):Given:
y = 8x - 9y = -8x + 7Add both the equations.
y = 8x - 9y = -8x + 7
2y = -2Divide 2 both sides.
2y = -2=> 2y/2 = -2/2=> y = -1Substitute the value of y into any equation.
y = 8x - 9=> -1 = 8x - 9Add 9 both sides.
=> -1 + 9 = 8x - 9 + 9=> 8 = 8xDivide 8 both sides.
=> 8/8 = 8x/8=> x = 1Solution (3):Given:
-x + 6y = 21y = -5x + 12Reorganize the first equation.
-x + 6y = 21=> 6y = x + 21Multiply the first equation by 5.
5(6y = x + 21)y = -5x + 12
30y = 5x + 105y = -5x + 12
Add both the equations.
31y = 117Divide 31 both sides.
31y = 117=> 31y/31 = 117/31=> y = 117/31Substitute the value of y into any equation.
-x + 6y = 21=> -x + 6(117/31) = 21=> -x + 702/31 = 651/31Subtract 702/31 both sides.
=> -x = 651/31 - 702/31=> -x = -51/31=> x = 51/31Boxes of granola are on sale of 2 for 4. 50. There are 12 ounces of granola in each box. What is the unit price of dollars per pound?
