If the corresponding heights of similar pyramids are in a ratio of 2:5. What will be the ratio of the volumes of the similar pyramids?
2:5
8:125
4:25
6:15

Answers

Answer 1

Answer:

2:5

Step-by-step explanation:

Shapes that are similar have the same ratio (and angle measurements), usually the only change in similar shapes is through a dilation or rotation.

The sum is (n-2)180. N is the number of sides. In this case, you have 20 sides. You get (20-2)180, which is 18x180 and results in 3240 degrees. This is the sum!! To get one angle, do the same thing but divide it by 20. The formula, as seen in the question, is (n-2)180/n. Therefore, you have (20-2) 180 divided by the number of signs, which is 20. Since 18 times 180 = 3240 is the (n-2)180, divide 3240 by 20. You get 162° for each angle.

What is tangent of an angle?

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

According to the given question.

We have a diagram in which we have two right angled triangles.

Now, in the upper right angled triangle

[tex]tan50 = \frac{0pposite side}{5}[/tex]

⇒ 1.19 = 0pposite side/ 5

⇒ opposite side = 1.19 × 5

⇒ opposite side = 1.2 × 5

opposite side = 6cm

Now, the opposite side w.r.t angle 50  degrees in the upper right angle triangle is a adjacent side w.r.t to angle 38 degrees in the lower right angle triangle.

So, in the lower right angle triangle.

[tex]tan38 = \frac{x}{adjacent side}[/tex]

⇒[tex]0.78 = \frac{x}{6}[/tex]

⇒ x = 0.78 × 6

⇒ x = 4.68

x = 7cm

Hence, the value of x in the given diagram is 7cm.

I got it wrong i need it help

Answers

Answer:

25

Step-by-step explanation:

Given,

Measurement of <1 = x + 10

Measurement of <2 = 4x + 5

Also, said in the question that both these angles are complementary.

Therefore, by the problem,

<1 + <2 = 90°

=> x + 10 + 4x + 5 = 90

=> x + 4x + 10 + 5 = 90

=> 5x + 15 = 90

=> 5x = 90 - 15 = 75

[tex] = > x = \frac{75}{5} [/tex]

=> x = 15

Now, we have got the value of x so,

Measurement of <1 is

<1 = x + 10 = 15 + 10 = 25 (Ans)

What is the result when the number 27 is increased by 1.6%?

Answers

27.432

Step-by-step explanation:

27 = 100%

divide by one hundred to get one percent

0.27 = 1%

Divide this by two to get 0.5%

0.135 = 0.5%

Divide by 5 to get 0.1%

0.027 = 0.1%

Add

0.27 + 0.135 + 0.027 = 0.432 =1.6%

Add 0.432 to 27

If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341) Don't forget units in your work and answer.

Step-by-step explanation:

Volume of Rectangular prism = L*W*H = 8*10*16 = 1280in

Volume of Cylinder = pi*r^2*H = 8*pi*r^2

We know that the diameter is 8 (because that's the height of the rectangular prism as stated in the question) and diameter is 2*r thus the radius of the cylinder is 4.

therefore the volume of the cylinder is 8*pi*(4)^2 which is 128pi If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341)

y is inversely proportional to x.when y=7 x=9 a) work out an equation connecting y and x b) work out the value of y when x=21

Answers

Answer:

a) y = k/x

7 = k/9

b) y = 3

Step-by-step explanation:

From the question, we are told that:

y is inversely proportional to x.

Mathematically:

y ∝ 1/x

y = k × 1/x

y = k/x

k = Constant of Proportionality

a) work out an equation connecting y and x

To find this Equation,

y = k/x

when y=7 x=9

Hence:

7 = k/9

b) work out the value of y when x=21

We find the value of k first

7 = k/9

k = 7 × 9

k = 63

Hence, the value of y when x=21

y = k/x

k = 63, x = 21

y = 63/21

y = 3

when a is positive
when a is negative
when b is positive
when b is negative

Answers

Answer:

B. when a is negative

Step-by-step explanation:

Inequality given:

ax + b > c

When solving we do steps:

ax > c - bx > (c - b)/a

At the second step both sides divided by a.

When a is positive the inequality symbol remains as is, when a is negative we have to divide both sides by -1 as well. This will reverse the inequality symbol.
