A coin is tossed 10 times:
How many times do you expect to get heads?
How many times do you expect to get tails?
Answers
Final answer:
The expected number of heads and tails when tossing a coin 10 times is 5 each.
Explanation:
If you toss a coin ten times:
Expected number of heads: 5
Expected number of tails: 5
This is because for each toss, the probability of getting a head is 0.5 (50%) and the same for a tail. Over multiple tosses, the outcomes tend to approach these expected values.
A rectangle has a perimeter of 60 inches and length of 22 what is the width of the rectangle
Answers
perimeter = 2l +2w
length = 22
perimeter = 60
60 = 2(22) +2w
60 = 44 +2w
subtract 44 from both sides
16 = 2w
w = 16/2
w = 8
width is 8 inches
The length of a rectangle is 2 cm longer than its width. if the perimeter of the rectangle is 36 cm , find its area.
Answers
The area of the rectangle is 80 square cm.
Explanation:To find the area of a rectangle, we need to know the length and width. Let's denote the width of the rectangle as 'w'. As given, the length of the rectangle is 2 cm longer than its width, so the length can be represented as 'w + 2'.
The perimeter of a rectangle is the sum of all four sides. In this case, it is given as 36 cm. Using the formula for the perimeter of a rectangle, we can set up the equation:
2(w + w + 2) = 36
Simplifying the equation:
4w + 4 = 36
4w = 32
w = 8
Substituting the value of 'w' back into the expression for length:
Length = 8 + 2 = 10
The area of a rectangle is given by the formula: area = length × width. So, the area of this rectangle is:
Area = 10 × 8 = 80 square cm

find sin x if cos x= 2/3 and x is in quadrant 4
Answers
This is actually pretty easy. All you have to do is know what quadrant your angle is in and that will determine the sign.
Quadrant1 = all trig functions are positive
Quadrant2 = sine is positive and cosine and tangent are negative
Quadrant3 = tangent is positive and sine and cosine are negative
Quadrant4 = cosine is positive and sine and tangent are negative
since your original angle is in quadrant 4 then the half angle will be in Quadrant 2
so the sine of the half angle is positive and the cosine of the half angle is negative
adjacent side = 2 and hypotenuse = 3 so opposite side will be -sqrt 5
so sin x = - sqrt5/ 3

Charlie drove 864 miles in 12 hours. at the same rate, how long would it take him to drive 504 miles?
Answers
It would take Charlie 7 hours to drive 504 miles.
The formula for this is Speed = Distance/Time. Time = Distance/Speed
864miles/12hrs = 72mph
With the same formula plug in 504 miles for Distance and leave time as X and speed will be 72mph.
72mph = 504miles/x
Cross multiply
72x = 504
Divide by 72
X = 7 hours

What is the least angle measure by which this figure can be rotated so that it maps onto itself? 45° 90° 180° 360° Left right double headed arrow.
Answers
In mathematics, specifically geometry, the least angle measure by which a regular, symmetric figure can be rotated to map onto itself is usually 90°. This concept falls under the umbrella of rotational symmetry.
Explanation:The question is about rotation of objects in geometry. To identify the least angle measure for a figure to map onto itself, we need to know the shape of the figure. However, assuming the figure is regular and symmetric (a square or a rectangle for example), the least angle measure by which it can be rotated to map onto itself is 90°.
It's important to remember the concept of rotational symmetry. A figure has rotational symmetry if it can be rotated less than 360° around a central point and still appear the same. For instance, a regular rectangle or square has a rotational symmetry of 90°, since we can rotate it 90 degrees and it appears the same.

-6x=-7.2---->x=7.2/6 or 1.27
4(1.27)+6y=7.2---->5.08+6y=7.2----> 6y=2.12
y=.35
x=lemons y=limes
Answer: The cost of 1 lemon is $1.2 and the cost of 1 lime is $0.4.
Step-by-step explanation:
Let x be the cost of 1 lemon and y be the cost of 1 lime.
Then for Ray, the equation representing total price will be :-
[tex]5x+3y=7.20[/tex]................................(1)
For Lia, the equation representing total price will be :-
[tex]4x+6y=7.20[/tex]..................................(2)
Dividing 2 on the both sides of equation (2), we get
[tex]2x+3y=3.60[/tex]...............................(3)
Subtracting (3) from (1), we get
[tex]3x=3.6\\\\\Rightarrow x=1.2[/tex]
Substitute value of x in (3), we get
[tex]2(1.2)+3y=3.6\\\\\Rightarrow2.4+3y=3.6\\\\\Rightarrow3y=1.2\\\\\Rightarrow y=0.4[/tex]
Thus, the cost of 1 lemon is $1.2 and the cost of 1 lime is $0.4.

What are the coordinates of point S"?
Answers
Answer:
S''(-3/2, 9/2)
Step-by-step explanation:
In a dilation, the coordinates of every ordered pair in the pre-image are multiplied by the scale factor to create the ordered pairs of the image.
The first dilation has a scale factor of 1/2. This maps:
R(-6, 10)→R'(-6/2, 10/2) = R'(-3, 5)
S(-2, 6)→S'(-2/2, 6/2) = S'(-1, 3)
T(-10, 0)→T'(-10/2, 0/2) = T'(-5, 0)
The second dilation has a scale factor of 3/2:
R'(-3, 5)→R''(-9/2, 15/2)
S'(-1, 3)→S''(-3/2, 9/2)
T'(-5, 0)→T''(-15/2, 0)
This makes S'' have coordinates (-3/2, 9/2).

Answers
It is found that there are 43,800 minutes in a month.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We knowt that there are 365 days per year, 24 hours per day, 12 months per year, and 60 minutes per hour.
1 day = 24 hour
1 hour = 60 minutes.
1 minutes = 60 seconds
Therefore, 24 hours = 24 x 60 = 1440 minutes
There are 1440 minutes in one day.
Then 30 days = 30 x 1440 = 43,800
Hence, It is found that there are 43,800 minutes in a month.

A.55 dimes and 165 quarters
B.98 dimes and 293 quarters
C.73 dimes and 98 quarters
D.165 dimes and 55 quarters
Answers
Answer:
A. 55 dimes and 165 quarters
Step-by-step explanation:
Given,
The number of pennies in the Jar = 220,
∵ There are 3 quarters for every 4 pennies,
i.e. 4 pennies = 3 quarters,
⇒ 1 penny = [tex]\frac{3}{4}[/tex] quarter
⇒ 220 pennies = [tex]220\times \frac{3}{4}[/tex]
[tex]=\frac{660}{4}[/tex]
= 165 quarter.
Therefore, there are 165 quarters.
Now, there is 1 dime for every 3 quarters,
i.e. 3 quarters = 1 dime
⇒ 1 quarter = [tex]\frac{1}{3}[/tex] dime,
⇒ 165 quarters = [tex]\frac{165}{3}[/tex] = 55 dimes.
Therefore, there are 55 dimes.

the value of (t) that satisfies the equation is approximately (37.6992).
Let's solve the equation [tex]\(-\frac{t}{4} = -3\pi\) for \(t\).[/tex]
Step 1: Multiply both sides by \(-4\) to isolate \(t\).
[tex]\[-\frac{t}{4} \times (-4) = -3\pi \times (-4)\][/tex]
This simplifies to:
[tex]\[ t = 12\pi \][/tex]
Step 2: Substitute the value of \(\pi\) to get the final answer.
[tex]\[ t = 12 \times 3.14159 \][/tex]
[tex]\[ t = 37.6992 \][/tex]
Therefore, the value of ( t ) is approximately ( 37.6992 ).
To solve the equation [tex]\(-\frac{t}{4} = -3\pi\) for \(t\)[/tex] , we first want to isolate (t) on one side of the equation. To do this, we can multiply both sides of the equation by (-4). This cancels out the fraction and leaves us with (t) on the left side:
[tex]\[-\frac{t}{4} \times (-4) = -3\pi \times (-4) \\t = 12\pi\][/tex]
Now, to get the numerical value of \(t\), we substitute the value of \(\pi\), which is approximately \(3.14159\), into the equation:
[tex]\[ t = 12 \times 3.14159 \][/tex]
[tex]\[ t \approx 37.6992 \][/tex]
Therefore, the value of (t) that satisfies the equation is approximately (37.6992).

It takes an older pump twice as long to drain a certain pool as it does a newer pump. working together, it takes the two pumps 3 hours to drain the pool. how long will it take the newer pump to drain the pool working alone
Answers
It would take the newer pump 4.5 hours to drain the pool working alone.
Given that,
It takes an older pump twice as long to drain a certain pool as it does a newer pump.
Let us assume that,
The time it takes for the newer pump to drain the pool alone is x hours.
Hence, According to the information given, the older pump takes twice as long, so it would take 2x hour to drain the pool alone.
Now, When both pumps work together, their combined rate of draining the pool is additive.
Therefore, the equation is,
[tex]\dfrac{1}{x} + \dfrac{1}{2x} = \dfrac{1}{3}[/tex]
Simplify the equation for x,
[tex]\dfrac{(2 + 1)}{2x} = \dfrac{1}{3}[/tex]
[tex]\dfrac{(3)}{2x} = \dfrac{1}{3}[/tex]
Cross multiplication,
[tex]3 \times 3 = 2x[/tex]
[tex]2x = 9[/tex]
Dividing both sides by 2:
[tex]x = 4.5[/tex]
Therefore, it would take the newer pump 4.5 hours to drain the pool working alone.
