Answer:

The height of cylinder is 9 cm

Step-by-step explanation:

Volume of cylinder = 198 cm³

Base Area = 22 cm²

We need to find height of the cylinder

The formula used is: [tex]Volume\:of\:cylinder=\pi r^2h[/tex]

Where [tex]Base\: Area = \pi r^2[/tex]

First we need to find radius r

[tex]Base\: Area = \pi r^2\\22=3.14\: r^2\\r^2=\frac{22}{3.14}\\r^2=7\\Taking\: square\: root\: on\: both\: sides\\\sqrt{r^2}=\sqrt{7}\\r=2.656[/tex]

So, we get radius r = 2.656

Putting values of volume and radius are to find height

[tex]Volume\:of\:cylinder=\pi r^2h\\198=3.14(2.656)^2h\\h=\frac{198}{22}\\h=9[/tex]

So, the height of cylinder is 9 cm

Step-by-step explanation:

87.50/125= 0.70

1-0.7-0.3

Answer:

42.9%

Step-by-step explanation:

So you would use [ ((V2 - V1) / |V1|) * 100 ]

V1 = 87.5 to V2 = 125

= ((125 - 87.5) / |87.5|) * 100

= (37.5 / 87.5) * 100

= 0.428571 * 100

= 42.8571% change

= 42.8571% increase

Then you round to 42.9!

The maximum height, in feet, of a ladder she can buy to fit through the door is, 6.7 feet

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

The shed in Stephanie’s back yard has a door that measures 6 feet high and 3 feet wide.

Now, By using Pythagoras theorem;

The length of a ladder she can buy to fit through the door is, x

⇒ x² = 6² + 3²

⇒ x² = 36 + 9

⇒ x² = 45

⇒ x = √ 45

⇒ x = 6.7 feet

Thus, The maximum height, in feet, of a ladder she can buy to fit through the door is, 6.7 feet

Answer:

3,250

Step-by-step explanation:

Let's go from left to right, using multiple of 12 times a power of 10 in the process.

What is the closest multiple of 12,000 (12 * 10^3) to 39,000 without going over? That's 3 (36,000). That's the thousands digit in this answer.

12,000 * 3 = 36000

39000 - 36000 = 3000

What's the closest multiple of 1,200 (12 * 10^2) to 3,000 without going over? That's 2 (2,400). That's the hundreds digit.

1,200 * 2 = 2,400

3,000 - 2,400 = 600

What is the multiple of 120 (12 * 10) closest to 600 without going over? That's 5 (600, it's even!). That's the tens digit. Since it goes evenly, 0 is the ones digit.

120 * 5 = 600

600 - 600 = 0.

The answer to 39,000 over 12 is 3,250.

Answer:

JK=8

Step-by-step explanation:

the sides are equal so set KL equal to LM

b+5=3b-1

b=6=3b

6=2b

b=3

b+5

3+5

8

Using the property of the sides of a rhombus, the missing length is determined as: B. JK = 8.

Thus:

KL = ML

Substitute

b + 5 = 3b - 1

b - 3b = -5 - 1

-2b = -6

b = 3

Find JK

JK = KL = b + 5

JK = b + 5

JK = 3 + 5

JK = 8

Therefore, using the property of the sides of a rhombus, the missing length is determined as: B. JK = 8.
