There are 6 wooden cubes, each of side 5 centimeters there total mass is 525 grams find the mass per cube. b)find the mass per cubic centimeter of a cube.

Answers

Answer:

(a) 87.5 g

(b) 0.7 g per cubic cm

Step-by-step explanation:

side of each cube, s = 5 cm

total mass, M = 525 g

(a) mass of each cube, m = M/6 = 525/6 = 87.5 g

(b) Volume of each cube = s x s  s = 5 x 5 x 5 = 125 cubic cm

mass per cubic cm = 87.5/125 =0.7 g per cubic cm

The perimeter of a rectangular park is 200 feet. The length of the park is 40 feet longer than the width.Find the length of the park.

What is the length of the park?
feet?​

Answers

[tex] \green{ \boxed{\sf \: length \: \: = 70 \: \: feet}}[/tex]

Step-by-step explanation:

Let assume that,

Wide = x

So,

length = x + 40

Given,

perimeter = 200 feet

We know that,

Perimeter = 2(length + wide)

So,

[tex]200 = 2(x + 40 + x) \\ = > \frac{200}{2} = 2x + 40 \\ = > 2x + 40 = 100 \\ = > 2x = 100 - 40 = 60 \\ = > x = \frac{60}{2} \\ = > x = 30 \: feet[/tex]

So length = x + 40 = 30 + 40 = 70 feet

Answers

Answer:

381/90

Step-by-step explanation:

x = 4.2333.... ----------(I)

Number of digit after decimal is 2 ( 4 , 3). So multiply both sides by of equation 100

100x = 423.333..... (II)

One digit (3) is repeating.So, multiply by both sides of equation (I) by 10

10x = 42.333....... -----(III)

Subtract Equation (III) from (II)

(II)     100x = 423.333......

(III)        10x =  42.333......  {Subtract}

         90x   = 381

                x = 381/90

Infinite solutions

Step-by-step explanation:

8y = 14 - 2x

⇒ 2x + 8y = 14 -----------(II)

[tex]\frac{a_{1}}{a_{2}}=\frac{1}{2}\\\\\frac{b_{1}}{b_{2}}=\frac{4}{8}=\frac{1}{2}\\\\\frac{c_{1}}{c_{2}}=\frac{7}{14}=\frac{1}{2}\\\\\frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}}=\frac{1}{2}[/tex]

So, infinite solutions

Answer:

G

Step-by-step explanation:

Given the 2 equations

x + 4y = 7 → (1)

8y = 14 - 2x → (2)

make x the subject of (1) by subtracting 4y from both sides

x = 7 - 4y

Substitute x = 7 - 4y into (2)

8y = 14 - 2(7 - 4y) ← distribute

8y = 14 - 14 + 8y

8y = 8y

Since both sides are equal this indicates the system has infinite solutions

Step-by-step explanation:

The sum of the angles in a triangle is 180°.

x + 75 + 50 = 180

x + 125 = 180

x = 55

Therefore, x = 55°.

Answer:

x = 55

Step-by-step explanation:

the angles of a triangle add up to 180 degrees. So far we have 125 taken up.

We do 180 - 125 = 55.

Answers

Step-by-step explanation:

I am not sure what you want to calculate as ultimate goal.

but your have an error already in your third line in the picture.

(3-6i)(2-4i) = 3×(2-4i) - 6i(2-4i)

you had there a "+" instead of a "-".

and then you made subsequent mistakes in every line, some of them are funnily bringing you more back to the real result (e.g. -12i + 12i would be 0 and not -24i, but if the third line would have been correct, then yes, -24i is actually needed) - but not completely.

= 3×2 - 3×4i - 6i×2 + 6i×4i =

= 6 - 12i - 12i + 24×-1 = 6 - 24i - 24 = -24i - 18

then in the last 3 lines you kind of lose it completely. I am absolutely not sure, what you are calculating, and where the "+" cube from instead of "×" (multiplications) and such.

(3+6i)(2+4i) = 3×2 + 3×4i + 6i×2 + 6i×4i =

= 6 + 12i + 12i + 24×-1 =

= 6 + 24i - 24 = 24i - 18

Answers

Answer:

294

Step-by-step explanation:

Surface area is the total area of the bases

The cube shown has a side length of 7

Cubes have 6 bases, each being a square, and the area of a square can be calculated by squaring the side length.

7^2 = 49

So the area of 1 base is 49

If we want to find the area of all the bases we multiply the area of 1 base by 6 ( because there are 6 bases )

42 * 6 = 294

The area of all of the bases is 294 so the surface area is 294

Given data :

x = 65, n = 300
