30/6 = 5

So, he needs to multiply all the ingredients by 5.

135 * 5 = 675

He needs 675g flour.

1 * 5 = 5

He needs 5 teaspoons of baking powder.

2 * 5 = 10

He needs 10 tablespoons of sugar.

130 * 5 = 650

He needs 650ml of milk.

1 * 5 = 5

He needs 5 eggs.

2 * 5 = 10

The formula c=5/9(f-32) is used to convert the temperature in degrees fahrenheit (

Dovator [93]

We are going to have to sub in 113 for f and solve for c

c = 5/9(f - 32)
c = 5/9(113 - 32)
c = 5/9(81)
c = 405/9
c = 45 <===

How much time would it take to earn $45 simple interest on an investment of $790 if the annual rate of return was 3.4%?

Tanzania [10]

Answer:

<u>I will take around 1 year and 8 months to earn $ 45 of interest on this investment</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Interest earned = $ 45

Investment = $ 790

Annual simple interest rate = 3.4% = 0.034

2. How much time would it take to earn $45?

Let's recall the formula for calculating the simple interest of an investment:

A = P * (1 + rt)

Replacing with the values we already have:

835 = 790 + (1 + 0.034t).

Where t is the time we want to calculate

835 = 790 + 26.86t

26.86t = 835 - 790

26.86t = 45

t = 1.68 (Rounding to the next hundredth)

<u>t ≅ 1 year and 8 months</u>

Your parents are buying a house for $187,500. They have a good credit rating, are making a 20% down payment, and expect to pay $

den301095 [7]

Sale price = 187500
20% down = 0.2 * 187500 = 37500
Loan amount = 187500-37500 = 150000
Interest = 4.65%/12 per month
Monthly payment = $1575
At the end of the first month, outstanding amount
= loan * interest rate - monthly payment
= 149006.25

Interest accrued during the first month
=150000*0.0465/12
= 581.25

Interest accrued during the second month
= outstanding amount at the end of the first month * (0.0465/12)
= 577.40

Total interest accrued during the first two months
= 581.25+577.40
= 1158.65 (to the nearest cent)

Answer: A) Yes, because the number can be written as the quotient of two integers

=====================================================

Explanation:

Any repeating decimal can be expressed as a fraction of two integers.

---------------------------------------

Optional section:

Here's a proof showing how the given number can be expressed as a fraction

Let x = 0.020020200202002...

The block of digits "02002" repeats forever.

Multiply both sides by 10^5 = 100,000 to move the decimal over 5 spots to the right.

The equation

x = 0.020020200202002...

will turn into

100000x = 2002.0200202002...

We have this system of equations

$\begin{cases} x = 0.020020200202002\ldots\\100000x = 2002.0200202002\ldots\end{cases}$

Subtracting said equations leads to

100,000x - x = 99,999x on the left

2002.0200202002... - 0.0200202002... = 2002 on the left

Note how the decimal portions line up perfectly to cancel out when we subtract

After those two subtractions, we end up with the equation

99,999x = 2002

Divide both sides by 99,999 and we isolate x

x = 2002/(99,999)

Use your calculator to find that,

2002/(99,999) = 0.02002020020202...

which helps confirm our answer.
