find the area use 3.14 for pi circle with a half line labled 4?

Answers

Answer 1

Answer:

50.24 units^2

Step-by-step explanation:

I'm assuming what half line means is radius so radius is 4.

The area formula is πr^2.

π(4)^2

3.14(4)^2

3.14x16=50.24

Area= 50.24 units^2

Answer:

24.3

Step-by-step explanation:

area of a rectangle =length*width

if we know at least the 2 quantities already

total area = 656.1

and one of the sides = 27

we have to divide the are by one of the sides to get the remaining side

width = area/length

656.1 divided by 27 equals 24.3

Which loan will cost its holder the most in interest?
A. $10,000 at 2 percent interest compounded for four years
B. $10,000 at 2 percent simple interest for four years
C. $5,000 at 4 percent simple interest for four years
D. $5,000 at 4 percent interest compounded for four years

Answers

Answer:

D. $5,000 at 4 percent interest compounded for four years

Hope this helps :)

The loan that will cost its holder the most in interest is option D. $5,000 at 4 percent interest compounded for four years.

To calculate the interest for each option, with the  use of the relevant interest formulas.

For option A, compounded interest, by the use of the formula:

[tex]CI =A -P\\CI=A = P(1 + r/n)^{nt} - P[/tex],

where:

A is the final amount,CI is the compound interest P is the principal, r is the interest rate, n is the number of times interest is compounded per year t is the number of years.

Plugging in the values, gives:

[tex]C.I= 10,000(1 + 0.02/1)^{(1\times4)} - 10,000[/tex]

By adding the value in the bracket gives:

[tex]C.I= 10,000(1 .02)^{4} - 10,000[/tex]

To evaluate [tex](1.02)^4[/tex],   raise 1.02 to the power of 4 gives:

[tex](1.02)^4 \approx 1.082432[/tex]

Substituting this value back into the expression:

[tex]CI\approx10,000 \times 1.082432- 10,000[/tex]

On multiplication gives:

[tex]CI\approx10824.32- 10,000[/tex]

On subtraction gives:

[tex]CI\approx 824.32[/tex]

2. For option B, simple interest, by the  use of the formula

[tex]SI = Prt[/tex]

where:

SI is the simple interest, P is the principal,r is the interest rate t is the number of years.

Plugging in the values, we get:

[tex]SI = 10,000\times( 0.02\times4)[/tex]

By multiplying the value in the bracket gives:

[tex]SI = 10,000\times 0.08[/tex]

On multiplication gives:

[tex]SI = 800[/tex]

For option C, simple interest  formula

[tex]SI = Prt[/tex]

where:

SI is the simple interest, P is the principal,r is the interest rate t is the number of years.

Plugging in the values, we get:

[tex]SI = 5,000\times( 0.04\times4)[/tex]

By multiplying the value in the bracket gives:

[tex]SI = 5,000\times 0.16[/tex]

On multiplication gives:

[tex]SI = 800[/tex]

For option D, compounded interest, we get:

A = 5,000(1 + 0.04/1)^(1*4) - 5,000 ≈ $6,181.73

For option D, compounded interest, by the use of the formula:

[tex]CI =A -P\\CI=A = P(1 + r/n)^{nt} - P[/tex],

where:

A is the final amount,CI is the compound interest P is the principal, r is the interest rate, n is the number of times interest is compounded per year t is the number of years.

Plugging in the values, gives:

[tex]C.I= 5,000(1 + 0.04/1)^{(1\times4)} - 5,000[/tex]

By adding the value in the bracket gives:

[tex]C.I= 5,000(1 .04)^{4} - 5,000[/tex]

To evaluate [tex](1.04)^4[/tex],   raise 1.04 to the power of 4 gives:

[tex](1.04)^4 \approx 1.1699[/tex]

Substituting this value back into the expression:

[tex]CI\approx5,000 \times 1.1699- 5,000[/tex]

On multiplication gives:

[tex]CI\approx5,849.2928- 5,000[/tex]

On subtraction gives:

[tex]CI\approx849.2928[/tex]

Comparing the final loan interest, option D has the highest value, indicating that it will cost its holder the most in interest.

And we need no find [tex]{\bf n(B\cup C)}[/tex] . At first Let me tell you that here [tex]{\sf (B\cup C)}[/tex] represents the union of the set B and C.And [tex]{\sf n(B\cup C)}[/tex] represents the cardinal no. of the respective set or no. of elements present in the respective set.So let's find the set [tex]{\sf (B\cup C)}[/tex] first

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{n(B\cup C)=7}}}[/tex]

Alternative Method :-

As we know that ;

[tex]{\boxed{\bf n(A\cup B)=n(A)+n(B)-n(A\cap B)}}[/tex]

Where [tex]{\sf (A\cap B)}[/tex] is the Intersection of A and B or the set of common elements of A and B. So now by same concept , now finding the intersection of B and C :-

[tex]{:\implies \quad \sf B\cap C=\{French\}}[/tex]

So , [tex]{\sf n(B\cap C)=1}[/tex] . Now , putting the values in the formula;

[tex]{:\implies \quad \sf n(B\cup C)=n(B)+n(C)-n(B\cap C)}[/tex]

4. Earl still hates to wash dishes and take out the trash. He finds his own weighted coin, one that
will randomly land on heads 30% of time. He will flip a coin once for each chore and will
perform the chore if the coin lands on heads.

A.) what is the probability that Earl will get out of the doing both chores?

B.) what is the probability that Earl will have to take out the trash but will not need to wash dishes?

Answers

Answer:

49%

21%

Step-by-step explanation:

Hello!

This is a probability question.

There is a 30% chance they need to do the chore and a 70% chance they don't for every coin toss.

Let's put this into fractions. 30% = 3/10. 70% = 7/10.

Now, to calculate a compound probability, we need to multiply the probability of each of the outcomes of the events.

A)

We have two events here. One where he doesn't do the chore and the other where he also doesn't do the chore.

Both events on their own have a 70% chance of happening or 7/10. So we multiply both the numbers together to find the compound probability. 7/10 * 7/10 = 49/100. 49/100 = 49%.

B)

We follow the same guidelines here. The probability of not doing the chore is 70% or 7/10, and the probability of doing the chore is 30%, or 3/10.

Now you need to multiply both probabilities. 7/10 * 3/10 = 21/100. 21/100 = 21%.
