Step-by-step explanation:

This is a subtraction.

4 7 - - 0 4

- - 1 3 4 -

4 0 4 3 5 7

The 7 in the result is the result o 14 - 7 so the last digit of 2nd no. is 7

4 7 - - 0 4

- - 1 3 4 7

4 0 4 3 5 7

The second '-' on the top row is 7 ( from 7 - 4). The 4 comes from the number 3 being increased by 1 ( carried form the second column).

4 7 - 7 0 4

- - 1 3 4 7

4 0 4 3 5 7

The first '-' on the top row is 5 ( 5 - 1) = 4)

4 7 5 7 0 4

- - 1 3 4 7

4 0 4 3 5 7

As the second digit on bottom row is 0 The first '-' on second row must be 7.

4 7 5 7 0 4

- 7 1 3 4 7

4 0 4 3 5 7

A scientist needs 60 liters of a 40% acid solution. He currently has a 20 % solution and a 50 % solution. How many liters of ea

Stella [2.4K]

percent ---------------- quantity

Acid type I 60.00% ---------------- x liters

acid type II 30.00% ------ 60 - x liters

Mixture 40.00% ---------------- 60

Total 60 liters

60.00% x + 30.00% ( 60 - x ) = 40.00% * 60

60 x + 30 ( 60 - x ) = 2400

60 x + 1800 - 30 x = 2400

60 x - 30 x = 2400 - -1800

30 x = 600

/ 30

x = 20 liters 60.00% Acid type I

40 liters 30.00% acid type II

To find the density:

⇒ must find the relationship between the density, mass, and volume

⇒ $Density = \frac{mass}{volume}$

Let's examine the information given:

weight: 1890g
dimensions: 8cm * 5cm* 5cm

Let's first find the volume:

⇒ the volume is the dimensions multiplied together

$Volume = 8cm * 5cm * 5cm = 200cm^3$

LEt's calculate the density now:

$Density = \frac{1890g}{200cm^3} =9.45g/cm^3$

Answer: The density of the copper is 9.45g/cm^3 or Choice (A)

Hope that helps!

4. Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number. The

a_sh-v [17]

4.) The lateral area of a figure is the area of the figure with the exception of the bases.
Given a prism with right triangle bases, the lateral area of the prism is the sum of the areas of the rectangles making up the prism.
This is given by
Lateral area = (8.94)(41) + (4)(41) + (8)(41) = 366.54 + 164 + 328 = 858.54 ≈ 859 m^2

The surface area is the sum of the bases plus the lateral area. The area of a rectangle is given by half base times height.
Surface area = 1/2 x 8 x 4 + 1/2 x 8 x 4 + 859 = 16 + 16 + 859 = 891 m^2

5.) The surface area of a cylinder is given by pi r^2h where r is the radius = 12 inches and h is the height = 17 inches.
Surface area = π x (12)^2 x 17 = 2,448π = 7,690.62 in^2 ≈ 7,691 in^2
