Answer:

3.98 meters

Step-by-step explanation:

First we need to know the formula for finding the height of a cylinder

[tex]h=\frac{V}{\pi r^2}[/tex]

Now That we know our formula, we just need to put in our numbers and simplify

[tex]h=\frac{5000}{\pi 20^2}[/tex]

[tex]h=\frac{5000}{1256.637}[/tex]

[tex]h=3.97887[/tex]

Now

[tex]\\ \rm\rightarrowtail V=\pi r^2h[/tex]

[tex]\\ \rm\rightarrowtail 5000\pi=\pi 20^2h[/tex]

[tex]\\ \rm\rightarrowtail 5000=400h[/tex]

[tex]\\ \rm\rightarrowtail h=50/4=12.5m[/tex]

Answer:

1. The area is approximately [tex]50.27m^{2}[/tex]

2.The area is approximately [tex]63.62ft^{2}[/tex]

Step-by-step explanation:

The formula for area of a circle is [tex]A=\pi r^{2}[/tex]

Answer:

[tex]\boxed{\tt \cfrac{4}{\$ 7.76} =\cfrac{13}{x} }[/tex]

Step-by-step explanation:

4 glue sticks cost $7.76.

[tex]\dashrightarrow \tt \cfrac{4}{\$\:7.67}[/tex]

let x represent the cost of 13 glue sticks. and now since 13 glue sticks cost x, we have the following proportion:

[tex]\dashrightarrow\tt \cfrac{13}{x}[/tex]

Cost changes along with the number of glue sticks purchased, and so the two proportions are equivalent.

[tex]\dashrightarrow\tt \cfrac{4}{\$ 7.76} =\cfrac{13}{x}[/tex]

Therefore, your answer is C !!!!!

Answer:

There are 28,000 sweat glands on a hand measuring 7 cm by 8 cm.

Step-by-step explanation:

We assume the palm has the shape of a rectangle.

The area of a rectangle is length × width.

The area of a palm measuring 7 cm by 8 cm is:

length × width = 7 cm × 8 cm = 56 cm²

Since 1 cm² has 500 sweat glands, 56 cm² has 56 times as many sweat glands.

500 × 56 = 28,000

Answer: There are 28,000 sweat glands on a hand measuring 7 cm by 8 cm.

Answer:

Perimeter_hexagon

= 78 inches

Step-by-step explanation:

"Regular hexagon" means the shape has 6 sides and all the sides are the SAME length.

"equilateral triangles" means the triangles all three sides are the same.

"perimeter" is distance around the outside of a shape.

see image.

So if the triangle has perimeter 39 inches. We divide to find the length of a side.

39/3

= 13.

The side of the triangle is also the side of the hexagon.

Perimeter of the hexagon is

P = 6•side

P = 6•13

P = 78

18 (d/2-5) = 171

1. If you apply the Distributive Property​ first, what operation will you need to use​ last?

    a. Multiplication

    b. Addition

    c. Division

    d. Subtraction

18 (d/2-5) = 171

[tex]18(\frac{d}{2}-5)=171 \\\\18(\frac{d}{2})+18(-5)=171\\\\\frac{18d}{2} -90=171\\\\9d-90=171\\\\+90\ \ \ \ \ +90\\\\9d = 261\\\\/9 \ \ \ \ /9[/tex]<== division was used last

2. If​ instead, you divide first to solve the equation what operation would you need to use​ last?

Answer:

  A.  21.2 m

Step-by-step explanation:

The perimeter of a polygon is the sum of its side lengths. A square is a polygon with four sides, all the same length. You can add up the side lengths, or you can take advantage of multiplication to do the repeated addition.

  P = 4s

  P = 4(5.3 m) = 21.2 m

The distance Yani walked was 21.2 meters.

Answer:

21.2 Meters

Step-by-step explanation:

The perimeter is 4n where n is the length of one side of a square.

1 side of the square patio is 5.3 meters.

4(5.3)=21.2

Side 2 is x+13

Side 3 is x

(4x) and (x) are like terms and can be combined

(x+13) must stay like this since the x is unknown.

Answer:

P = 3x + 17

Step-by-step explanation:

length = x, side = x + 4, side = x + 13

How do u need help ill help u anyway i can

Step-by-step explanation:

Answer:

x = 34

Step-by-step explanation:

By Pythagoras theorem:

[tex] {x}^{2} = {(16)}^{2} + {(30)}^{2} \\ \\ = 256 + 900 \\ \\ = 1156 \\ \\ \implies \: x = \sqrt{1156} \\ \\ \implies \: x =34[/tex]

Answer:

x = 34 cm

Step-by-step explanation:

Using Pythagorean Theorem,

a² + b² = c²

Values given :-

a and b = 16 and 30

c = x

Substitute :-

x² = (16)² + (30)²

x² = 256 + 900

x² = 1156

x = √1156

x = 34 cm

Answer:

red: y=2x+5

yellow: y=-3x+5

black: y=2x-6

blue: x=5

Step-by-step explanation:

Answer:

As an example, we have 26 plus 36,

To add these two numbers, we first consider the "ones" column and calculate 6 plus 6, which results in 12. Since 12 is greater than 9 (remembering that base 10 operates with digits 0-9), we "carry" the 1 from the "ones" column to the "tens column" and leave the 2 in the "ones" column.

Considering the "tens" column, we calculate 1 + (2 + 3), which results in 6. Since 6 is less than 9, there is nothing to "carry" and we leave 6 in the "tens" column.

Answer: (to the example) - 62
