Answer 1

Answer:

3200 cm

Step-by-step explanation:

Given,

Length of the rectangle = 12 meters = 1200 cm

Width of the rectangle = 400 cm

Therefore,

Perimeter of the rectangle = 2(l+w)

= 2(1200+400) cm

= 2 × 1600 cm

= 3200 cm (Ans)

Answer 2

Answer:

3200 cm

Step-by-step explanation:

12m = 12,000 cm so therefore the answer is 3200cm

Step-by-step explanation:

123 + 36 + x = 180

159 + x = 180

(159 - 159) + x = 180 - 159

x = 21

36 + 21 + x = 180

57 + x = 180

(57 - 57) + x = 180 - 57

x = 123

CDE = 123 + 36 + 21

ABC = 123 + 36 + 21

Step-by-step explanation:

w = 50 - L

For what value of t is f (t) = 0.0625

Answers

9514 1404 393

Answer:

t = 4

Step-by-step explanation:

It can be useful to convert the numbers to ratios of integers.

0.0625 = (0.5)^t

1/16 = (1/2)^t

1/2^4 = 1/2^t

4 = t . . . . . . . match exponents

If you like, you can solve this using logarithms.

0.0625 = 0.5^t

log(0.0625) = t×log(0.5)

t = log(0.0625)/log(0.5)

t = 4

Morty makes $200,000 a year selling stocks. If he loses 33% of his salary to taxes, what
does he make each week?
(explain work)
whoever responds this problem will get crown

Answers

Answer: $134,000

Step-by-step explanation:

We know that morty makes $200,000 a year. 1.00 or (100%)

We know the government takes 33% or (.33) of morty's annual income, to which we would get the equation (below)

200,000 x .33= x= 66,000

we subtract the $66,000 from the $200,000 to figure out the final answer

200,000-66,000

Final Answer

= $134,000

nothing years?

Answers

Answer:

2.5 years

$736 in interest

Step-by-step explanation:

The relationship between the values in an amortization is ...

A = P(r/12)/(1 -(1 +r/12)^(-12t))

Here, we have A = 140, P = 3400, r = 0.16 and we want to find t

140 = 3400(0.16/12)/(1 -(1 +0.16/12)^(-12t))

1 -(1 +0.16/12)^(-12t) = 1/3.0882353

(1 +0.16/12)^(-12t) = 0.67619048

Taking logarithms gives ...

-12t·log(1 +0.16/12) = log(0.67619048)

t = log(0.67619048)/(-12·log(1+0.16/12)) ≈ 2.46177

It will take about 2.5 years to pay off the loan.

The total of payments is ...

(2.46177)(12)($140) = $4135.77

so, the interest paid is ...

$4135.77 -3400 = $735.77

You will pay about $736 in interest over the life of the loan.

_____

Additional comment

The number of payments is calculated to be about 29.54. You would probably make 30 payments, with the last payment being a different amount than $140. The actual amount will depend on when the payment is made, and the amount of it that is finance charge. We believe the remaining balance after 29 payments will be $75. After a full month, the finance charge due on that amount is $1.00, bringing the total amount of interest paid to $736.

If the loan is paid off in the middle of the month, the interest due is reduced. Above, we have calculated interest based on a last payment made part way through the month. We rounded up, partly because of the ambiguity in the final payment.

Evaluate piecewise function.

Shown in the picture please
help!

Answers

4 only fits into the interval 2 < x ≤ 7 (the bottom one listed), so you only need to do the calculation as if your function was f(x) = -6.

Now this is both a simple and tricky function, f(x) = -6. It’s tricky, because there’s no x on the right side. But that’s what makes it simple, once you understand how that works.

Since there isn’t any x on the right side, the output/y-value is just always -6. There’s no calculation needed to do.

So, f(4) = -6.

Recap:
Step 1: figure out which piece of the function to use
Step 2: evaluate the function only using that piece.

All you need to do to find the decimal form of a fraction is to take the numerator and divide it by the denominator :

2 / 3 = 0.6666666.... and keeps going

= 0.67
