Answers

Answer:

Speed of the parachutist is meters per second [tex]2.083[/tex] meter per second

Distance travelled in 2 seconds [tex]4.167[/tex] meter

Step-by-step explanation:

Speed of the parachutist is kilometers per hour = 180

Speed of the parachutist is meters per second [tex]\frac{180*1000}{24*60*60} = 2.083[/tex] meter per second

Distance travelled in 2 seconds [tex]2.083 *2 = 4.167[/tex] meter

A and B are similar solid cylinders base area of A : base area of B = 9 : 25

complete these ratios

curved surface area of A : curved surface area of B : = ? : ?

height of A : height of B = ? : ?

Answers

Answer:

Two figures are similar if the figures have the same shape but different sizes.

Then if we have two figures X and X'

Such that one dimension of X is D, the correspondent dimension on X' will be:

D' = k*D

Such that k is the scale factor that relates the figures.

1:k

Because all the dimensions will be rescaled by the same scale factor k, we can conclude that any surface on X will be related to the same surface in X' by:

S' = k^2*S

then the ratio of the surfaces is:

1:k^2

While the relation between the volumes will be:

V' = k^3*V

Here the ratio is:

1:k^3

Ok, in this case we have two cylinders

We know that the ratio between the base area ( a surface) is:

9:25

a) We want to find the ratio: curved surface area of A : curved surface area of B

Because again we have a surface area, the ratio should be exactly the same as before, 9:25

b) height of A : height of B

In this case, we have a single dimension.

Because in the rescaling of a surface we need to use k^2, then we can conclude that the ratios:

9:25

is related to k^2

Then the ratio, in this case, is given by applying the square root to both sides of the previous ratio, so we get:

√9:√25

3:5

This is the ratio of the heights.

Also from this we could get the value of k, that is the right value when we leave the left value equal to 1, we can get that if we divide both sides by 3.

(3/3):(5/3)

1:(5/3)

Then:

k = 5/3

a). Common difference = 4

b). [tex]T_n=4n+3[/tex]

c). 51st term = 207

Step-by-step explanation:

Given arithmetic sequence is,

7, 11, 15, 19......

a). Common difference = Second term - First term

                                      = 11 - 7

                                      = 4

b). nth term of an arithmetic sequence is given by,

   [tex]T_n=a+(n-1)d[/tex]

   Here, n = number of term

   a = First term

   d = common difference

   By substituting the values in the given formula,

   [tex]T_n=7+(n-1)4[/tex]

   [tex]T_n=4n+3[/tex]

c). 51st term of the sequence will be,

   [tex]T_{51}=7+(51-1)4[/tex]

         = 7 + 200

Find the area of the shade region.round to the nearest tenth

Answers

Answer:

189.25

Step-by-step explanation:

first you find the area of the entire circle which is π times (14.5) squared so 210.25π. then you find the triangle which is 1/2 20×21= 21 then subtract 210.25π by 21= 189.25

Answer:

450.5 in²

Step-by-step explanation:

The area of the triangle

= (20×21)/2

= 210 in²

The hypotenuse of the triangle

=[tex] \sqrt{ {20}^{2} + {21}^{2} } [/tex]

=[tex] \sqrt{400 + 441} [/tex]

=[tex] \sqrt{841} [/tex]

= 29 in

The hypotenuse of the triangle (29 in)

= the diameter of the circle

The formula of area of a circle= πr²

The radius of the circle

= 29÷2

= 14.5 in

The area of the circle

= π × 14.5²

= 660.5 in² (rounded to the nearest tenth)

The area of the shaded region

= 660.5 - 210

= 450.5 in²

In a display at a museum, two planets have volumes of 8 cubic inches and 27 cubic
inches. What is the ratio of their diameters?
2:3
413.5
2:9
4:13.5

Answers

Answer:

2:3

Step-by-step explanation:

V = 4/3*pi*r^3

Diameter = 2r

The ratio of diameters of the two planets has volumes of 8 cubic inches and 27 cubic will be 2/3.

What is Ratio?

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other such that they should not be divisible.

The upper number is called as the numerator and the lower is called the denominator.

For example, 3/4 where 3 will be numerator and 4 will be denominator.

Given that the In a display at a museum, two planets have volumes of 8 cubic inches and 27 cubic.

Now volume of planets(sphere) = πD³/6 where D is diameter of sphere

So volume of first planet / volume of second planet ∝ (dia or first)³/(dia of second)³

⇒ V₁/V₂  ∝ (D₁/D₂)³

Given that V₁/V₂ = 8/27

So 8/27 =  (D₁/D₂)³

D₁/D₂ = 2/3

Hence, the ratio of diameters of two planets will be 2/3.

In the triangle below,
x = [? ] cm. Round to the
nearest tenth.
y
X
90°
20
10 cm
X=?

Answers

Answer: y ≈ 10.6 cm

Step-by-step explanation:

The cosine function relates the adjacent side to the hypotenuse in a right triangle. The side adjacent to the 20° angle is 10 cm.

cos(20°) = (10 cm)/y

y = (10 cm)/cos(20°)

y ≈ 10.6 cm

The approximate value of the variable x will be 3.64.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The base of the right angle triangle is 10 cm, the perpendicular is x, and the hypotenuse is y.

Then the value of y will be given by the cosine of angle 20°.

cos 20° = 10/y

          y = 10.64 cm

The approximate value of the variable x is given by the Pythagoras theorem.

     H² = P² + B²

10.64² = x² + 10²

113.25 = x² + 100

      x² = 113.25 – 100

      x² = 13.25

       x = 3.64
