Answer:
4/663 or .6%
Step-by-step explanation:
P(Queen) = 4/52 or 1/13
P(4) = 4/51 (51 cards because the first card drawn was not replaced)
multiply the probabilities together to get:
1/13 x 4/51 = 4/663

How do i solve these problems
Answer:
X = 13
X = 70
Step-by-step explanation:
1. Since it is a right angle set the equation up as X +2 + 75 = 90.
X =13
2. Set up x - 20 + 40 = 90 since right triangles are 90 degrees
x = 70

Answer:
(9+13)/2*10
=22/2*10
=11*10
=110
Step-by-step explanation:
First, we figure out the formula for areas of trapezoids is (a+b)/2*h.
Next, we plug in the numbers which will give use the equation:
22/2*10
Lastly, we solve:
11*10=110
Solve for b
4b+5=1+5b
Answer: b=4
Step-by-step explanation: 4b+5=1+5b = B = 4
Answer:
b = 4
Step-by-step explanation:
subtract 4b from 5b and you get 1b. subtract 1 from 5 and u get 4 = 1b. divide both sides by 1 therefore b = 4

what is the circumference of this circle r = 2 km
Answer: 4*pi, or 12.57 rounded to the nearest hundredth.
Step-by-step explanation: Circumference= pi*diameter. Diameter=2*radius. Radius=2, so diameter=4. 4*pi=12.57
Bill has saved $825 from his last 8 paychecks. He saved either $75 or $150 a paycheck. Formulate and solve a system of equations. to determine how many times bill saved $75 from his paycheck.
Answer: 5 times
Step-by-step explanation:
Let the number of times that he saved $75 be x.
Let the number of times that he saved $150 be y.
Therefore, based on the information given in the question, we can form an equation which will be:
x + y = 8 ...... i
75x + 150y = 825 ....... ii
From equation I,
x + y = 8
y = 8 - x....... iiii
Put equation iii into ii and this will be:
75x + 150y = 825
75x + 150(8 - x) = 825
75x + 1200 - 150x = 825
75x - 150x = 825 - 1200
-75x = -375
x = 375/75
x = 5
He saved $75 5times from his paycheck.
Write this expression in the fewest number of terms: x+3y+2x+10+2y+12
Answer:
3x+5y+22
Step-by-step explanation:
Answer:
3x + 5y + 22
Step-by-step explanation:
Given expression:- x + 3y + 2x + 10 + 2y + 12
Here, you can add all the 'x' terms together and 'y' terms together.
There is an 'x' and '2x'.
On adding them, you get 2x + x equals 3x.
Then add the 'y' terms
There is a '3y' and a '2y'. On adding them, you get 3y + 2y equals 5y.
Then add the numbers that are left. 12 and 10.
12 + 10 equals 22.
Then take all the values we got after addition:- 3x, 5y and 22.
2x, 5y and 22 cannot be added together. So, the expression in the simplified form would be:-
3x + 5y + 22How the heck do you do the onion skin math method?

40 POINTS QUESTION
PLS HELP
A Ferris wheel with a radius of 19m rotates once every 56 seconds. The top of the
wheel is 42.5m above the ground.
Determine a sine and cosine equation of the function that gives the rider's height
above the ground in metres, as a function of time, in seconds, with the rider starting
at the bottom.
Answer:
(First of all its 20 points not 40 but any ways) A ferris wheel has a raidus of 20 m. Passengers get on halfway up on the right side. The direction of rotation is counter clockwise. The bottom of the ferris wheel is 2 m above ground. It rotates every 36 seconds. Determine height above the ground after 15 seconds algebraically. Determine seconds to the nearest tenth when height is 38 m above the ground algebraically.
**
let t=seconds after wheel starts to rotate.
let h=meters above ground after wheel starts to rotate
..
The formula I got: h(t)=20sin(πt/18)+22
This is close to the formula you got, except I left the negative sign out since passengers start to rise after the wheel starts going counter-clockwise.
..
After 15 seconds:
h=20sin(15π/18)+22
=20sin(5π/6)+22
=20*(1/2)+22
=32 m
..
When h=38 m
38=20sin(πt/18)+22
38-22=20sin(πt/18)
20sin(πt/18)=16
sin(πt/18)=16/20=4/5=.8
arcsin(.8)=0.927
πt/18=0.927 (radians)
t=(.927*18)/π≈5.31
..
height above the ground after 15 seconds≈38 m
seconds elapsed when height is 38 m above ground≈5.3 seconds
