Help pleaseeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

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

Estimate the perimeter and area of the figure to the nearest whole number. Please help!!

solniwko [45]

Answer:

29 ; 37

Step-by-step explanation:

The figure is composed by a square, a rectangle, and a right triangle

The perimeter of the square is 6 units

The perimeter of the rectangle is 10 units

The triangle is composed by a side of 6 units and a side of 5 units

The third side can be find with the Pythagorean theorem

$\sqrt{6^2 + 5^2} = \sqrt{36 + 25} = \sqrt{61}$ = 7,81025

The total perimeter is

6 + 10 + 5 + 7,81025 = 28,81025 = 29

Area of the square = 2^2 = 4 square units

Area of the rectangle = 6 x 3 = 18 square units

Area of the triangle = (5 x 6)/2 = 15 square units

Total area = 4 + 18 + 15 = 37 square units
