Answer:
Let's find how many letters California has first, c-a-l-i-f-o-r-n-i-a has 10 letters.
Now let's find how many letter A's are in the word California, California has two a's in the word.
So there are 2 cards out of 10 that could possibly be selected as the letter A.
Your probability is:-
2/10 which simplifies to 1/5, if you wanted to make this a percentage as well;
1/5 * x/100
solve for x;
20%
The required probability of turning over an A is given as 20% or 0.2.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
California = C, a, l, i, f, o, r, n, i, a = 10 letters
So,
Number of card = 10
Now,
there are two a's in the card deck
So the probability of turning over an A,
= 2 / 10
= 0.2 or 20%
Thus, the required probability of turning over an A is given as 20% or 0.2.

The diameter of a circle is 36 inches. What is the circle's area?
use 3.14 for PI
but only windowssssssssssssssssssss
The area of the circle is the region occupied by it in the two dimensional plane.
Area of a circle is given by ;
➝ πr²The diameter of the circle is 36inches
ㅤㅤㅤ➙ Radius = D / 2
ㅤㅤㅤ➙ Radius = 36 / 2
ㅤㅤㅤ➙ Radius = 18 inches
Therefore, area :
➝ A = πr²
➝ A = 3.14 × ( 18 )²
➝ A = 3.14 × 324
➝ A = 1017.36
Solution:
We know that:
Diameter of circle = 36 in.Radius of circle = Diameter/2 in.Area of circle = πr²Finding the radius of the circle:
Radius of circle = Diameter/2 in.=> Radius of circle = 36/2 in.=> Radius of circle = 18 in.Finding the area of the circle:
Area of circle = πr²=> Area of circle = (3.14)(18²)=> Area of circle = (3.14)(324)=> Area of circle = 3.14 x 324 = 1017.36 in²A mechanic alters the lighthouse to make the light rotate in such a way that is reflection travels north word along the wall at a constant rate of 100 ft./s how fast in radians per second is the beam of light rotating when the lights reflection is 100 feet north of the point on the wall that is closest to the lighthouse
Answer:
The correct solution will be "1 Rad/sec".
Step-by-step explanation:
The given value is:
Velocity (V)
= 100 ft./sec
As we know,
Angular velocity,
⇒ [tex]\omega=\frac{V}{R}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{100}{100}[/tex]
⇒ [tex]=1 \ Rad/sec[/tex]
What is the value of x?
The sum of all the angles of a triangle is 180 degrees
We see that Line HI and JI are equal in length meaning that triangle HIJ is an isosceles triangle. This means that the two angles of unknown measure are both x.
So lets now set up our equation:
[tex]x + x + 74 = 180\\2x = 106\\x = 53[/tex]
Thus x is 53 degrees
Hope that helps!

What is the value of the equation 3×-9y=1?
A.3 B. 9 C. 1 D. -9
Answer:
y = -1/27
Step-by-step explanation:
3 * -9y = 1
~Simplify left side
-27y = 1
~Divide -27 to both sides
y = -1/27
Best of Luck!
anybody know this answer?
Answer:
y = -4/5x + 3
Step-by-step explanation:
Chose any two points on the line:
(5, -2)
(-5, 6)
Slope = (y2 - y1) / (x2 - x1)
6 -(-2) / -5 - 5
8 / -10
-4/5
Equation:
y = mx + b
Plug in x and y using any coords and then plug in m (the slope):
-2 = -4/5 * 5 + b
-2 = -20/4 + b
-2 = -5 + b
Add 5 on both sides:
3 = b
Now our equation is:
y = -4/5x + 3

What is m
A)30
B)60
C)90
D)50
Answer:
A) 30°
Step-by-step explanation:
All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°
Answer:
m Is 30
Step-by-step explanation:
m is 30
because....the sum of angles in a triangle is 180
75+75+m =180
150+m=180
make m the subject of the formula
m=180-150
m=30

The freshman class is selling candy bars to raise money. They purchased 3100 candy bars and paid a delivery fee of $35. The total cost, including the delivery fee, was $1430. What was the cost of each candy bar?
Answer:
$0.45
Step-by-step explanation:
To answer this question, we first have to subtract the delivery fee from the total cost:
1430 - 35 = 1395
Now, we divide this number by the total amount of candy bars:
1395 / 3100 = 0.45
So, each candy bar costs $0.45
Hope this helps :)
Each candy bar would be 45 cents
at a hockey game the snack bar sells nachos 2 dollars and pretzels for 3 dollars. The snack bar sold 49 nachos and pretzels all together for $137 dollars
Answer:
The total number of nachos sold:49
The total number of pretzels sold:13
Step-by-step explanation:
The numbers of nachos is 49. Each nacho costs 2 dollars.
2 x 49 = 98
Then you subtract that amount to get the amount of money left for pretzels.
137 - 98 = 39
Then you divide 39 by 3 since that's the cost of each pretzel.
39 ÷ 3 = 13
13 is the amount of pretzels you can buy after you buy 49 nachos.
