If you divide 35 (amount of detergent in the container )into 1.25 (the 1 1/4 cups) your answer would be that you can do 28 loads , and if you had 3 boxes you would be able to do 84 loads because you just need to multiply the previous answer by 3

Answer:

1. 2507.034 g

2. 1243mg

0.001243kg

1,243,000 mcg

3. 162.5g

Step-by-step explanation:

1. First of all we need to convert 30mg and 2.5kg to gram.

⇒ 1 gram = 1000 milligrams

x = 35mg

⇒ 1000mg(x) = 35mg

⇒ x = 35mg = 35 = 0.035g

1000mg 1000

Next we convert 2.5kg to gm.

⇒ 1 kilogram = 1000g

2.5kg = x

(We then criss cross)

⇒ x = 2.5kg × 1000g = 2500g = 2500g

1kg 1

Now that we converted them all to gram, we will add them.

⇒ 30mg + 2.5kg + 7g = 0.035g + 2500g + 7g = 2507.035 ≈ 2507g

2. We convert 1.234g into

a. mg

⇒ 1 gram = 1000 milligram

1.243g = x

⇒ x = 1.243g × 1000mg = 1243mg = 1243mg

1g 1

b. kg

⇒ 1 kilogram = 1000gram

x = 1.243 gram

⇒ x = 1.243g × 1kg = 1.243kg = 0.001243kg = 1.243 × 10⁻³ kg

1000g 1000

c. mcg

⇒ 1 gram = 1000000mcg

1.243g = x

⇒ x = 1.243g × 1,000,000mcg = 1,243,000mcg = 1,243,000mcg

1 g 1

3. We need 500 aspirin, the amount of grams needed and we know that one tablet contains 325mg.

So now we can derive the formula such that:

⇒ 1 tablet = 325mg

500 tablet = x

But first we need to convert 325mg to grams.

⇒ 1 gram = 1000mg

x = 325mg

⇒ x = 325mg × 1 g = 325g = 0.325g

1000mg 1000

So now instead of using 325mg we can use 0.325g.

⇒ 1 tablet = 0.325g

500 tablets = x

⇒ x = 500 tablets × 0.325g = 162.5g = 162.5g

1 tablet 1

A graphing calculator displays 1.89 x 10^12 as 1.89e12. How do you think it would display 1.89 x 10^-12? What does the e stand f

Lerok [7]

What you need to know for this case is that the calculator is using the scientific notation in two different ways:

Way 1:

$a * 10 ^ b$

Way 2:

$aeb$

Where, in both cases:

a, b: they are real numbers.

Therefore, for the following number:

$1.89*10^{-12}$

We have an equivalent way is:

$1.89e-12$

Answer:

$1.89e-12$

The e refers to the exponent to which the base 10 is elevated.

Ian puts 300.00 into an account to use for school expenses the account earns 6%interest compounded annually how much will be in

romanna [79]

This problem is about componded interest. The formula for compounded interest is:

$\begin{gathered} \text{Amount}=\text{Initial}\cdot(1+r)^t \\ \text{Where,} \\ \text{Amount is the total acumulative at time t.} \\ \text{Initial is the initial amount, at t=0} \\ r\text{ is the interest in decimal number.} \\ t\text{ is the time accordingly the interest, in this case is in years.} \end{gathered}$

In this case, Initial = 300, r = 0.06 and t=10 so the total amount in the account after 10 years is:

$\begin{gathered} \text{Amount}=300\cdot(1+0.06)^{10} \\ \text{Amount}=300\cdot1.06^{10} \\ \text{Amount}=300\cdot1.79085 \\ \text{Amount}=537.255 \end{gathered}$

The amount after 10 years is 573.26.
