Answer 1

Answer:

The spheres are similar as their radius will be in the ratio

What is a Sphere?

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere = ( 4/3 ) πr³

where r is the radius of the sphere

Given data ,

Let the first sphere be represented as A

Now , the radius of the sphere A = r₁

Let the first sphere be represented as B

Now , the radius of the sphere B = r₂

And , the volume of sphere A , V₁ = ( 4/3 ) πr₁³

The volume of sphere B , V₂ = ( 4/3 ) πr₂³

The ratio of V₁ / V₂ is given by

V₁ / V₂ = ( 4/3 ) πr₁³ / ( 4/3 ) πr₂³

On simplifying , we get

V₁ / V₂ = r₁³ / r₂³

So , the spheres are similar by their ratio of radius

Hence , all the spheres are similar in ratios

Find the measure of angle x in the figure below: A triangle is shown. At the top vertex of the triangle is a horizontal line aligned to the base of the triangle. The angle formed between the horizontal line and the left edge of the triangle is shown as 52 degrees, the angle formed between the horizontal line and the right edge of the triangle is shown as 59 degrees. The angle at the top vertex of the triangle is labeled as y, and the interior angle on the right is labeled as 63 degrees. The interior angle on the left is labeled as x.

Answers

y = 180 - 52 - 59 = 69 degrees . . . . . . . . (angles on a straight line are supplementary, i.e. add up to 180 degrees)

x = 180 - 69 - 63 = 48 degrees . . . . . . . . (sum of interior angles of a triangle is 180 degrees)

Therefore, m/_x = 48 degrees.

The measure of the interior angle x as shown in the triangle below is 48°

Triangle

A triangle is a polygon with three sides and three angles. Types of triangles are obtuse, scalene, isosceles and equilateral. The sum of all angles in a triangle is 180 degrees.

From the diagram:

y + 52 + 59 = 180° (sum of angles in a straight line)

y = 69°

x + y + 63 = 180° (sum of angles in a triangle)

x + 69 + 63 = 180

x = 48°

The measure of the interior angle x as shown in the triangle below is 48°

Cameron got 18 out of 20 problems correct on the test.What percent did she make

Answers

She got 90% correct. How? Do 18 divided by 20. You get 0.9 which is equal to 90%

She got 90% because you multiply 18 and 20 by 5 and it equals to 90/100. So, 90% is an A.

Joe what's to build a fence for his dog Charlie he plans to surround the rectangle to the right with fence. How many feet will he need

Answers

Joe wants to build a fence for his dog Charlie.
The lengths of the perimeter of the rectangle that he plans to surround with fence are as follows:

10 feet + 15 feet + 10 feet + 15 +feet.

The total perimeter area of a rectangle is worked out as follows:
10 + 15 + 10 + 15 = 50
Therefore Joe needs 50 feet of fencing to totally surround the rectangle with fence.
