9. Thirty percent of the metal sphere will be covered in a metal that is tinted red. What is the area of the section of the sphere that is tinted​ red?

please help :))

Answers

Step-by-step explanation:

Given that,

8. The radius of a sphere, r = 115 cm

We need to find the surface area of the metal​ sphere. The formula for the surface area of a sphere is given by :

[tex]A=4\pi r^2[/tex]

Put all the values,

[tex]A=4\times 3.14 \times (115)^2\\\\=166106\ cm^2[/tex]

9. Thirty percent of the metal sphere will be covered in a metal that is tinted red.

So, the area of the section that is tinted red is :

[tex]A=30\%\ of\ 166106\\\\=\dfrac{30}{100}\times 166106\\\\=49831.8\ cm^2[/tex]

Hence, this is the required solution.

Billy and Tommy are playing a dice game with a six-sided die. Billy needs to roll a 5 or higher to win the game. What is the probability that Billy will roll a 5 or higher?

Answers

Answer:

Probability that Billy will roll a 5 or higher [tex]=\frac{1}{3}[/tex]

Step-by-step explanation:

Probability refers to chances of occurrence of any event.

If a six-sided die is thrown, possible outcomes are [tex]1,2,3,4,5,6[/tex].

Billy needs to roll a 5 or higher to win the game.

So,

Favorable outcomes are [tex]5,6[/tex]

Number of favorable outcomes [tex]=2[/tex]

Total number of outcomes [tex]=6[/tex]

Probability that Billy will roll a 5 or higher

= Number of favorable outcomes ÷ Total number of outcomes

 [tex]=\frac{2}{6}[/tex]

 [tex]=\frac{1}{3}[/tex]

Juana is measuring two pyramids whose base are isosceles right triangles. The second pyramid has the same height, but has 9 times the volume. What is the side length of its base

Answers

9514 1404 393

Answer:

  3 times the smaller triangle base

Step-by-step explanation:

The volume is proportional to the height and to the area of the base.

If the height is unchanged, the larger pyramid must have a triangular base with an area that is 9 times the smaller base area.

Since the bases are similar, the area ratio is the square of the side length ratio. The side lengths of the larger base triangle must be √9 = 3 times the side lengths of the smaller base triangle.

Explain how to use a number line to find the sum 7 + −2.

Answers

Step-by-step explanation:

start at 7 on the number line. move to the left (because the value is negative) 2 jumps. you will land on 5.

Answer: 5

Step-by-step explanation:

Usually you would just do 7+-2 which is also 7-2 which equals 5 but since it's a number line you do this

You would locate 7 on the number line and do the same for -2

Once done, you would take the distance 2 is from 0 and push 7 there(basically moving it to 5) and that would be how you would use a number line to find the sum of 7 + -2

Now if the 2 was positive, this would be different and you would add the distance making it 9 but since it's negative you push it towards 0 which makes it 5

Answers

Answer: B. 4x*2x^2+4x*(-2)+1*4x+1*(-2)

Step-by-step explanation: Hope this help :D

Answer:

A. 4x * 2x^2 + 4x * (-2) + 1 * 2x^2 + 1 * (-2)

Step-by-step explanation:

We have the binomial (4x + 1)(2x^2 - 2) and are asked to see how it looks like expanded.

When solving binomials, we need to follow the FOIL method :

First - First number in first parenthesis multiplied by first number in second parenthesis

Outer - First number in first parenthesis multiplied by second number in second parenthesis

Inner - Second number in first parenthesis multiplied by first number in second parenthesis

Last - Second number in first parenthesis multiplied by second number in second parenthesis

If we follow the definitions given, we can find our correct answer and also see where all the other answers mess up at :

A. 4x*2x^2+4x*(-2)+1*2x^2+1*(-2)

This follows FOIL entirely from start to finish.

B. 4x*2x^2+4x*(-2)+1*4x+1*(-2)

This did not follow the Inner part of FOIL.

C. 4x*2x^2+4x*(1)+1*2x^2+1*(-2)

This did not follow the Outer part of FOIL.

Tangents C B and C B intersect at point C outside of the circle. A line is drawn to connect points C and O. We are given that angle AOB is a central angle of circle O and that angle ACB is a circumscribed angle of circle O. We see that AO ≅ BO because . We also know that AC ≅ BC since . Using the reflexive property, we see that . Therefore, we conclude that △ACO is congruent to △BCO by the .

Answers

Answer:

all radii of the same circle are congruent

SSS congruency theorem

Step-by-step explanation:

The triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.

Given: ∠AOB is a central angle and ∠ACB is a circumscribed angle.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

We know that the radius and the tangent are perpendicular to each other.

Then the angle ∠CAO and angle ∠CBO are of 90°.

We know that the tangent of the circle drawn from the point outside the circle will be 2, and these tangent are of equal length.

In triangle △ACO ≅ △BCO, we have

CO = CO (Common side)

∠CAO = ∠CBO = 90°

OA = OB (Radius)

Thus, the triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.
