Answer:
Aisha has 24 2p coins and 24 1p coins, then she has in total:
2p*(24) + 1*p*(24) = 48p + 24p = 72p
Step-by-step explanation:
Suppose that we have a set of N elements in a bag (if the bag is closed and we put our hand inside to grab one element, we could not distinguish them apart), and K of these elements have a given property (for example, these are red).
The probability of selecting at random one of these red elements is equal to the quotient between the number of elements with that property (K) and the total number of elements in the bag (N)
P = K/N
Now let's go to our problem.
We have 24 1p coins.
We have X 2p coins.
Then the total number of coins is: (24 + X)
We know that the probability of choosing at random a 2p coin is then:
P = X/(24 + X)
And we know that this is equal to 1/2
Then:
X/(24 + X) = 1/2
X = (1/2)*(24 + X) = 24/2 + X/2
X = 12 + X/2
X - X/2 = 12
X/2 = 12
X = 2*12 = 24
Then Aisha has 24 2p coins.
Aisha has 24 2p coins and 24 1p coins, then she has in total:
2p*(24) + 1*p*(24) = 48p + 24p = 72p
A building casts a shadow that reaches10 ft. Out from the base of the building. The length of shade from the top of the building to the end of the shadow is 26 ft. How tall is the building?
Answer:
24 ft
Step-by-step explanation:
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
26^2 = 10^2 + length^2
676 - 100 = length^2
length = 576
find the square root
= 24

A. Use the formula to verify that turkey sandwiches and 9-grain wheat are
independent events. Show your work or explain how you found your
answer.
Answer:
Proved
Step-by-step explanation:
See attachment for the given parameters.
Required
Prove that turkey sandwiches and 9-grain wheat are independent events
From the attachment, we have:
[tex]P(T) = 23.6\%[/tex]
[tex]P(W) = 51.7\%[/tex]
The intersection between both is:
[tex]W\ and\ T = 36[/tex]
So:
[tex]P(W\ and\ T) = \frac{36}{300}[/tex]
[tex]P(W\ and\ T) = 0.12[/tex]
[tex]P(W\ and\ T) = 12\%[/tex]
For both events to be independent, the following must be true.
[tex]P(W\ and\ T) = P(W) * P(T)[/tex]
[tex]P(W\ and\ T) = 23.6\% * 51.7\%[/tex]
[tex]P(W\ and\ T) = 12.2\%[/tex]
The calculated values of P(W and T) are estimates
[tex]12.2\% \approx 12\%[/tex]
Hence, both events are independent

Marta's dog just had six puppies. Four are female (F), and two are male (M). One of the males is brown. Two of the females are brown. All puppies are either brown or white. If Marta randomly gives away puppies to her friends, what is the probability of a friend getting a puppy that is male, brown, or both?
4. What is the probability that a puppy Marta gives away is male, brown, or both? Explain.
Answer:
male= 1/3 brown =1/2, both 1/6
Step-by-step explanation:
there is 2 males and 6 total, simplified is 1/3. there are 3 browns and 3 whites, so simplified is 1/2 instead of 3/6. There is only one brown male, so you cannot simplify it more than 1/6.

We are assuming that only one puppy is given away!
Step-by-step explanation:
6 puppies in total
4/6 are female 2/6 are male
2/6 female and brown 2/6 female and white 1/6 male and brown 1/6 male and white
We want all of the male population which is 2/6 and the 2/6 of the female population that are brown added together

Write the ratio as a fraction in simplest form: 18 minnows to 32 fish
Answer:
9/16
Step-by-step explanation:
Use the Part = 18, as the numerator and use the Whole = 32, as the denominator. The part-to-whole fraction is 18/32
Meaning:
The Part is 18/32 of the Whole
Reducing the fraction, it is also true that:
The Part = 9/16 of the whole
Write an equation to represent the measures of the angles

72 paper clips to 63 paper clips
find the change in percent
Answer:
The number of paperclips decreased by 12.5%
Step-by-step explanation:
72-63=9
9/72 = .125 or 12.5%
Answer:
Step-by-step explanation:
To get percentage change, we use the formula:
Percentage change =
Here,
the new value is the later value of 63 and the old value is the first value of 72
Plugging in the values in the formula gives us:
Percentage change =
The percent change is 12.5% (we can also say that it is a decrease of 12.5% since negative)
Given figure is a solid made up of a cone and a hemisphere.
The total height of ther figure is 20 cm and the slant height of
the cone is V218 cm. If the centimeter measure of the radius
of the base is a multiple of 7, find the volume of the solid
figure.
Answer:
5514.67 cm³
Step-by-step explanation:
The computation of the volume of the solid figure is shown below
Given that
The total height is 20 cm
The slant height is 218 cm
radius of the base is 7 cm
the height of the hemisphere would be equivalent to the radius i.e. 7 cm
the height of the cone is
= 20 cm - 7 cm
= 13 cm
Now the volume of the cone is
= πrl
= 3.14 × 7 × 218
= 4796 cm^3
The volume of the hemisphere is
= 2 ÷3 πr^3
= 2 ÷ 3 × 3.14 × 7^3
= 718.67 cm3
Now the volume of the solid figure is
The volume of solid= volume of cone + volume of the hemisphere
= 4796 + 718.67
= 5514.67 cm³

Answer:
A = 216.314
C = 52.124
Step-by-step explanation:
We know the radius so now we need to know the diameter. So multiple the radius by 2.
R = 8.3
D = 16.6
Let's find the area first
A = 3.14×r²
A = 3.14×68.89
A = 216.314
Now find the circumference
A = 3.14×d
A = 3.14×16.6
A = 52.124

Is the dilation an enlargement or a reduction base on the picture attached ?how can u tell ?
NEED HELP ASAP !
Answer:
Reduction
Step-by-step explanation:
Whenever you see a shape graphed where the points have ' after the letter, then that is the RESULT. So, the yellow parallelogram ABCD is the original, and the blue parallelogram A'B'C'D' is the result, which is obviously smaller than the original. So that means that it's a reduction.
I hope this made sense and helped! :)
Answer:
Step-by-step explanation:
The yellow rectangle is an enlargement of the blue one, and is a positive dilation. The blue rectangle is shrunken from the yellow one and is a negative dilation.
Yan is climbing down a ladder. Each time he descends four rungs on the ladder, he stops to see how much farther he has to go
Question:
Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?
4+4+4+4
8+8+8+8
(-1)(4+4+4+4)
(-8) + (-8) + (-8) + (-8)
Answer:
[tex]Total = (-8) +(-8) +(-8) +(-8)[/tex]
Step-by-step explanation:
Given
[tex]Rungs = -4[/tex] --- It is negative because he is climbing down
[tex]Steps = 8[/tex]
Required
An expression for the number of rungs climbed
To do this, we simply multiply the number of rungs by the steps taken.
[tex]Total = Rungs * Steps[/tex]
[tex]Total = -4 * 8[/tex]
This can be rewritten as:
[tex]Total = -8 * 4[/tex]
The product, when written as sum is:
[tex]Total = (-8) +(-8) +(-8) +(-8)[/tex]
