Answer:

<u>953.78in^3</u> of grain

Step-by-step explanation:

You use the equation π r^2 h to find the volume of the cylinder

r = radius of the base = 9/2

= 4.5 in and the height h = 15 in

the volume is 3.14 * 4.5^2 * 15

= 953.78 in^3.

Answer:

953.78 in³

Step-by-step explanation:

Volume = Area circle x height

Step 1: Area of the Circle

Formula = πr²

3.14 * (4.5*4.5) =

3.14 x 20.25 ≈ 63.59

63.59 x 15 ≈ 953.78

If my answer is incorrect, pls correct me!

6) What are ED and FD?

kolezko [41]

Answer:

ED = 12 and FD = 24

Step-by-step explanation:

See the attached diagram.

The perpendicular distance between the three parallel lines are same i.e. AB = BC = 8

Therefore, the parallel lines will divide any transverse line ( say FD ) in 1 : 1 ratio i.e. will divide equally.

Therefore, FE = ED = 12 units.

Again, FD = FE + ED = 12 + 12 = 24 units. (Answer)

5. 3x + 5y + 5z =1<br> x - 2y = 5<br> 2x + 4y = 11

lilavasa [31]

Answer:

see explanation

Step-by-step explanation:

Given the 3 equations

3x + 5y + 5z = 1 → (1)

x - 2y = 5 → (2)

2x + 4y = 11 → (3)

Use (2) and (3) to solve for x and y

Multiply (2) by 2

2x - 4y = 10 → (4)

Add (3) and (4) term by term

4x = 21 ( divide both sides by 4 )

x = $\frac{21}{4\\}$

Substitute this value of x into (3)

2 × $\frac{21}{4\\}$ + 4y = 11

$\frac{21}{2\\}$ + 4y = 11 ( subtract $\frac{21}{2\\}$ from both sides )

4y = $\frac{1}{2}$ ( divide both sides by 4 )

y = $\frac{1}{8\\}$

Substitute the values of x and y into (1) and solve for z

3 × $\frac{21}{4\\}$ + 5 × $\frac{1}{8\\}$ + 5z = 1

$\frac{63}{4}$ + $\frac{5}{8}$ + 5z = 1

$\frac{131}{8}$ + 5z = 1 ( subtract $\frac{131}{8}$ from both sides )

5z = - $\frac{123}{8}$ ( divide both sides by 5 )

z = - $\frac{123}{40}$

Solution is

x = $\frac{21}{4\\}$ , y = $\frac{1}{8\\}$ , z = - $\frac{123}{40}$

When 5 times a number is added to 45 the answer is the sm of 85 and 140 what is the number

zimovet [89]

Hello.

First, let the number be r.

5 times r is written like this:

$\rm{5r}$

Now, add 45:

$\mathrm{5r+45}$

Now, the sum of 5r+45 is equal to the sum of 85 and 140:

$\mathrm{5r+45=85+140}$

In order to solve this equation, we need to add 85 and 140:

$\mathrm{5r+45=225}$

Now, subtract 45 from both sides:

$\mathrm{5r+45-45=225-45}$

$\mathrm{5r=225-45}$

$\mathrm{5r=180}$

The last step is to divide both sides by 5:

$\mathrm{r=36}$

Therefore, the answer is

$\rm{r=36}$

I hope it helps.

Have a nice day.

In parallelogram FGHJ if m∡ GHJ=55˚ find m∡FGH

hodyreva [135]

Answer:

∠ FGH = 125°

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary, then

∠ FGH + ∠ GHJ = 180° , that is

∠ FGH + 55° = 180° ( subtract 55° from both sides )

∠ FGH = 125°
