Answer 1

Answer: $m=0.001\ some\ unit\n\n400\ mg=400\cdot0.001\ g=\boxed{0.4\ g}$

Answer 2

Answer: There are 1000 milligrams, or mg, in one gram, or g. Therefore, we have 400/1000=4/10=.4 grams in 400 milligrams. The fourth answer is the best one.

Nadine bought 5 quarts of oil for her car. How many fluid ounces is that?

Answers

Answer:

5 quarts is equal to 160 fluid ounces.

Step-by-step explanation:

Nadine bought 5 quarts of oil for her car. How many fluid ounces is that?

The relation between 1 quart and number of fluid ounces is :

1 quart = 32 fluid ounces.

So, 5 quarts will be = $5*32=160$ fluid ounces.

Hence, we can say that Nadine bought 160 fluid ounces for her car.

1 quart = 32 fluid ounces.

So, 5 quarts = ? fluid ounces.

Lets solve to find ?.

5 × 32 = 160

So, Nadine bout 160 fluid ounces (5 quarts) or oil for her car.

ACCORDING to the rate of electricity charge, the minimum charge up to 20 unit is Rs 80 and the cost per unit from 21 units to 250 units is Rs 7.30. How many units were consumed by Rs 1248?

Answers

Answer:

180

Step-by-step explanation:

let x = total units of electricity after 250 units

the total units of electricity consumed can be determined using the formula below

80 + 7.3x = 1248

7.3x = 1248 - 80

7.3x = 1168

divide both sides of the equation by 7.3

x = 1168 / 7.3

x = 160

total electricity consumed = 160 + 20 = 180

160

The lateral area of a cube is 36 square inches. How long is each edge?

Answers

The length of the edge of the given cube that has a lateral area of 36 square inches is: 3 inches.

What is the Lateral Area of a Cube?

Lateral area of a cube = 4a², wherea is the length of each edge of the cube.

Given the parameters:

Lateral area = 36 square inches
Length of each edge = a = ?

4a² = 36

a² = 36/4

a² = 9

a = 3 inches.

Length of each edge of the cube = 3 inches.

#SPJ2

Cubes have three square sides. The area of one side is the edge length squared:
36 = L^2
L = sqrt(36) = 6
The volume of a cube is edge length cubed:
V = L^3 = 216 cubic inches

Eighty-four is what percent of 212? 3.962% 39.62% 2.52% 25.2%

Answers

Answer:

Option B, 39.62%

Step-by-step explanation:

We have to find 84 is what percent of 212.

For this we will put 84 in the numerator and 212 in the denominator to find the fraction first.

Then we will multiply this fraction by 100 to get the percentage.

Fraction of 84 to 212 = $(84)/(212)$

= $(21)/(53)$

Now the percentage will be $(21)/(53)* 100$

= 39.62%

Option B, 39.62% is the correct answer.

The value of percentage 84 is of 212 is 39.62%, the correct option is B.

We are given that;

Percentage= 84%

Number= 212

Now,

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

To find the percentage, we need to divide 84 by 212 and then multiply by 100.

By solving

84 / 212 = 0.3962

0.3962 x 100 = 39.62

Therefore, by percentage the answer will be 39.62%.

What is the area, in square centimeters, of the shape below?

Answers

Answer:

21.46 cm squared

Step-by-step explanation:

3.8x5.8=21.46

Final answer:

The area of a shape can be calculated by multiplying its dimensions. Given a rectangle with length 0.6238 cm and width 6.6 cm, you would multiply these figures to get an area of 4.1 cm².

Explanation:

To calculate the area of a shape in square centimeters, you need to know the dimensions of the shape. For example, if you have a rectangle, you would multiply its length by its width to get the area. If the length was 0.6238 cm and the width was 6.6 cm, the area would be 0.6238 cm x 6.6 cm = 4.11708 cm². However, we often round to two significant figures, so the area would be 4.1 cm². Remember that area is expressed in square units, so for centimeters, the area would be in square centimeters.
