I=25.5

Answer:

The cylinder has the larger volume. this is because the formula for the volume of a cone and cylinder are the same but the cone has the fraction 1/3.

So, three cones can fit into the cylinder, so it is less then one half

Given:

Consider the below picture attached with this question.

The given expression is:

[tex]\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}[/tex]

To find:

The next step.

Solution:

We have,

[tex]\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}[/tex]

Cancel out the common factors.

[tex]=3m-\dfrac{4}{3}-\dfrac{2}{m}[/tex]

Therefore, the correct option is D.

Which neighbor's fencing project will take the most amount of time to complete?  Neighbor C

Answer:

The Answer is 69.27

Step-by-step explanation:

Answer:

8 in.

Step-by-step explanation:

The ratio of the surface areas is equal to the square of the ratio of the heights

Let h = the height of the smaller dodecagonal pyramid

So,  [tex]\frac{2080}{130} = \frac{32^{2}}{h^{2} }[/tex]

[tex]h^{2} = \frac{32^{2} * 130 }{2080}[/tex]

[tex]h^{2} = 64[/tex]

h = 8 in.

Answer:

72π feet

Step-by-step explanation:

circumference of circle= 2πr

Diameter= 2(radius)

radius of circle

= 72 ÷2

= 36 ft

Circumference

= 2(π)(36)

= 72π ft

Answer:

I don't know lol

Step-by-step explanation:

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

Answer:

70degrees

Step-by-step explanation:

Using the theorem;

Angle at the vertex is the half of the difference of the angles at its intercepted arcs

Angle at the vertex = 24 degrees

difference of the angles at its intercepted arcs = 118 - x

According to the theorem;

24 = 1/2(118 - x)

Cross multiply

24 * 2 = 118 - x

48 = 118 - x

x = 118 - 48

x = 70degrees

Hence the value of x is 70degrees

Answer:

the number of dozen cookies donated altogether is [tex]7\frac{3}{4}[/tex]

Step-by-step explanation:

Given that

The store donated 4 1 ÷ 2 dozen cookies

And, the another store donated 3 1 ÷ 4 dozen cookies

we need to find oyt the no of dozen cookies donated altogether is

[tex]= 4 \frac{1}{2} + 3 \frac{1}{4} \\\\= \frac{9}{2} + \frac{13}{4} \\\\= \frac{18 + 13}{4} \\\\= \frac{31}{4}\\\\= 7\frac{3}{4}[/tex]

Hence, the number of dozen cookies donated altogether is [tex]7\frac{3}{4}[/tex]

x = 242.7 m

Step-by-step explanation:

First we need to find the angle at one of the parachutists:

180 - 57 - 43 = 80°

We then use sine law to find the distance between the parachutists

[tex] \frac{x}{ \sin(57) } = \frac{285 \: m}{ \sin(80) } [/tex]

Solving for x

[tex]x = (\frac{ \sin(57) }{ \sin(80) } )(285 \: m) = 242.7 \: m[/tex]

Answer:

504

Step-by-step explanation:

Answer:

2x = 140  x = 70

Step-by-step explanation:

If you add the other 2 angles together, you get 150. Subtract 150 from 360 to get 210. Divide that by 3 and you get 70. Because QRS is 2 times the size of PQR, it is equal to 140.

Hope that this helps!

Explanation:

The sum of the interior angles of a quadrilateral is 360°.

x + 2x + 80 + 70 = 360

3x + 150 = 360

3x = 210

or

x = 70°

Therefore

angle Q = 70°

angle R = 2x = 140°

Answer:

feel like its C

Step-by-step explanation:

Answer:

Heather served 10 orders.

Felipe served 30 orders.

Jim served 50 orders.

What we know:

Let's refer to each person by their first initial (H, J, & F)

H + J + F = 90

F = 3 * H

J = 5 * H

Substitution:

Let's replace F and J by their equivalents in relation to H (basically making the entire left side only H)

H + (5 * H) + (3 * H) = 90

H + (5H) + (3H) = 90

9H = 90

H = 90/9

H = 10

Final Calculations

Now that we know how many orders Heather served, we can calculate how many Jim and Felipe served

F = 3 * H

F = 3 * 10

F = 30

J = 5 * H

J = 5 * 10

J = 50

Answer:

3(x+4)=-18

x+4= -18 -3

x+4= -21

x= -21 -4

x= -25
