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

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:

[tex]b = \sqrt{ \frac{ {c}^{2} }{2 {\pi}^{2} } - {a}^{2} } [/tex]

Answer:

x<12

Step-by-step explanation:

Let's solve your inequality step-by-step.

−3< x/ −4

Step 1: Simplify both sides of the inequality.

−3< −1/ 4 x

Step 2: Flip the equation.

−1/ 4 x>−3

Step 3: Multiply both sides by 4/(-1).

( 4/ −1 )*( −1/ 4 x)>( 4 /−1 )*(−3)

x<12

Answer:

x<12

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:

816

A=a+b/ 2  h=13+38 /2·32=816

Answer:

The area is 816 [tex]m^2[/tex]

Step-by-step explanation:

The formula for the area of a trapezoid is

A= [tex]\frac{a+b}{2}[/tex]h

A and B are the bases and h stands for the height

So, then you can input all of your known variables

A= [tex]\frac{38 +13}{2}[/tex](32) ( honestly, you could just input all of this into a calculator)

A= [tex]\frac{51}{2}[/tex](32)

A= 816

The answer is letter B. the second one

The single expression that represents the surface area of the rectangular prism is :

S= 2lw + 2lh + 2wh

Let us assume the l is length, width is w and h is the height of the rectangular prism.

What is the rectangular prism?

In geometry, a rectangular prism can be stated as a 3-dimensional solid shape that has 6 faces with its base as rectangles.

So, the surface area S would be :

S = surface area

S= 2lw + 2lh + 2wh

where,

l= length

w= width

h = height

Therefore, the surface area of the rectangular prism is :

S= 2lw + 2lh + 2wh

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.

The correct statement about the angles of ΔABC is,

⇒ m ∠B > m ∠C > m ∠A

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Sides of the triangle ABC are,

BC = 13

CA = 20

AB = 19

We know that;

Opposite angle of the larger side of the triangle are large.

Here, we have;

CA > AB > BC

Hence, We get;

⇒ m ∠B > m ∠C > m ∠A

Thus, The correct statement about the angles of ΔABC is,

⇒ m ∠B > m ∠C > m ∠A

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: lisa's sister is 3

Step-by-step explanation:12-6 is 6 then 6/2 is 3 so the check lets do it backwards 3*2 is 6 +6 because Lisa is 6 years older than twice her sister's age

The equation is y = 2x + 6. Then the age of her sister will be 3 years old.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Lisa is six years older than her younger sister. Lisa is twelve years old.

Let y be the age of Lisa and 'x' be the age of her sister. Then the equation is given as,

y = 2x + 6

If the age of Lisa is 12. Then the age of her sister is calculated as,

12 = 2x + 6

2x = 12 - 6

2x = 6

x = 6 / 2

x = 3

The equation is y = 2x + 6. Then the age of her sister will be 3 years old.
