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

Which best describes how to determine the decimal number that is modeled? 7 of 100 parts have been shaded, and 7 hundredths is w

Elina [12.6K]

Answer:

7 of 100 parts have been shaded, and 7 hundredths is written as 0.07

Step-by-step explanation:

Note that we have a grid of 100 squares and 7 of those squares are shaded. We can represent the shaded portion by saying 7/100 which is equivalent to .07.

With this information, we can say 7 out of 100 is shaded and is representative of 7 hundredths.

Note that each digit after the decimal is a multiple of (1/10). We can express this as (1/10)^n where n is the digit place after the decimal.

In this case, we have 7, two digits after the decimal so it will be equivalent to 7 * (1/10)^2 = 7 * (1/100) = 7/100.

Cheers.

Which features are present in this polar graph?

Blababa [14]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\texttt {D. Symmetry about the polar axis Theta = 0}$

____________________________________

$\large \tt Solution \: :$

The given graph is symmetric along Theta = 0

[ polar axis ]

Because it's a horizontal line that divides the features on the graph into two equal halves. and there's no other suitable symmetric relation.

Isaac walks 6/10 of a mile of a mile in 1/5 of an hour. If Isaac’s walking rate remains constant, what is Isaacs walking rate in

mezya [45]

Answer:

3 miles per hour.

Step-by-step explanation:

To get his walking rate in miles per hour, we multiply 1/5 by its reciprocal, 5/1. We also multiply 6/10 by 5/1. This gets us 30/10 of a mile in an hour. We can simplify 30/10 to 3. This means he walks at 3 miles per hour.
