Step-by-step explanation:

1. volume of a cylinder = pi x radius squared x height (I wasn't sure which was the radius/diameter)

2. 615.74

3. 1km

4. rearrange formula for volume of the cylinder to get the radius on 1 side. divide both sides by height and pi to leave u with r². then divide by the square root.

formula= r=square root of 3080³/3.14 × 20

5. height = volume/ pi x radius squared

6. 2463.01

7. 28.01

8. 145.955 m

9. 21.01

10. 17

Answer:

<h2>total no of markers :36</h2>

in first condition

<h2>no of blue marksers :4</h2>

so probability:

\frac{4}{36}  =  \frac{1}{9}

same goes to the second condition

Please solve. Will mark brainilest

Answer:

x = -3\frac{11}{20}

Step-by-step explanation:

Convert the mixed fractions to improper fractions;

⇒\frac{-19}{4} = x - \frac{6}{5}  

⇒ \frac{-71}{20} = x   [add 6/5 to both sides]

⇒ x = -3\frac{11}{20}   [convert to mixed fraction]

For 11 and 12, find... a.) The slope of the line parallel to the line that passes through the given points, and b.) The slope of
Minchanka [31]

(11)

we are given two points

(x1,y1)=(0,3)

(x2,y2)=(8,7)

so, we get

x_1=0,y_1=3

x_2=8,y_2=7

(a)

we know that slope of parallel lines are always equal

so, we can use formula

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug values

m=\frac{7-3}{8-0}

m=\frac{4}{8}

m=\frac{1}{2}............Answer

(b)

we know that slope of perpendicular line is -1/m

so,

slope=\frac{-1}{m}

now, we can plug value

slope=\frac{-1}{\frac{1}{2}}

slope=-2...............Answer

(12)

we are given two points

(x1,y1)=(5,-1)

(x2,y2)=(3,1)

so, we get

x_1=5,y_1=-1

x_2=3,y_2=1

(a)

we know that slope of parallel lines are always equal

so, we can use formula

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug values

m=\frac{1+1}{3-5}

m=\frac{2}{-2}

m=-1............Answer

(b)

we know that slope of perpendicular line is -1/m

so,

slope=\frac{-1}{m}

now, we can plug value

slope=\frac{-1}{-1}

slope=1...............Answer

If points a,b,c,d and ,e are collinear and in that order. Find AC if AE = x+50 and CE=x+32
Alla [95]
By the segment addition postulate,
AC + CE = AE so AC = AE - CE
AC = (x+50) - (x+32)
AC = x+50-x-32
AC = 18
