A rhombus has sides 10 cm long and an angle of 60°. Find the diagonals of the rhombus.

Answers

Since all the sides are equal, the altitude is

10 sin60° = 5√3

To see this, draw the rhombus ABCD and drop an altitude from D to AB. Now you have a right triangle with hypotenuse=10 and base angle=60°

How many solutions are there to this system of equations? On a coordinate plane, 2 lines have equations y = one-fourth (x minus 4) and y = one-fourth x minus 1.
a. one solution
b. no solution
c. infinitely many solutions
d. it cannot be determined without solving

Answers

Answer:

b. no solution

Step-by-step explanation:

y=1/4x-4

y=1/4x-1

This pair of equations has the same slope, meaning that they are parallel lines. Parallel lines never intersect so there is no result of solving this system of equations. Therefore, the correct answer would be b, that this system of equations has no solution.

Answer:

NO solution

Answer: (4)

Step-by-step explanation:

At step 2 the student rewrites 6 as 2*(4), and 8x as 2*(6x). This is incireect, since 2*(4) is actually 8, and 2*(6x) is 12x.

The correct way to do it is to rewrite 6 as 2*(3), and rewrite 8x as 2*(4x), which corresponds to the answer option (4)

What is the volume of the figure below, in cubic centimeters?

2 rectangular prisms. One prism has a length of 16 centimeters, width of 6 centimeters, and height of 2 centimeters. The other prism has a length of 15 centimeters, width of 6 centimeters, and height of 30 centimeters.
A.) 2,700
B.) 2,712
C.) 2,892
D.) 3,072

Answers

The large cube is representing: 16*16*32= 8192cm

And the small cube is representing: 16*6*2= 72cm

length(cm) × width(cm) × height(cm) = cubic centimeters(cm³)

&

length(mm) × width(mm) × height(mm) ÷ 1000 = cubic centimeters(cm³)

So, answer would be 2,712.

How do you find the radius for a sphere?

10 Points shall be awarded for answering!

Answers

Given diameter: r = d / 2,
Given area: r = √[A / (4 * π)],
Given volume: r = ³√[3 * V / (4 * π)],
Given surface to volume ratio: r = 3 / (A/V).


Some equations based on what is given :)
If given the diameter, divide by 2. For example if the diameter is 16, that would mean the radius would be 8. If the problem doesn’t state the diameter, divide the circumference by pi. So if the circumference was 24, that would make the diameter 7.639437268. From there you divide that by 2 to get the radius. Hope this helps!

A scale model of the front view of Tony’s house is shown. What is the minimum amount of paint needed for two coats?

A. 594 square centimeters
B. 297 square centimeters
C. 216 square centimeters
D. 81 square centimeters

Answers

Answer:

594 square centimeters

The minimum amount of paint needed for two coats will be 297 square centimeters. Then the correct option is B.

What is the area?

Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.

The shape is a combination of the rectangle and the triangle. Then the area of the shape is calculated as,

A = 1/2 x 18 x 9 + 18 x 12

A = 81 + 216

A = 297 square centimeters

The minimum amount of paint needed for two coats will be 297 square centimeters. Then the correct option is B.

How far will a skier travel in 2 1/2 minutes? Explain how you figured it out.

You can’t answer this because you don’t know how fast the skiers goin

The distance traveled by the skier traveled in 2 1/2 minutes is A = 2,700 m

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

Let the distance traveled by the skier in 4 seconds = 72 m

And , let the distance traveled by the skier in 2 1/2 minutes = A

where 2 1/2 minutes = 150 seconds

Now , the proportion is

A / 150 = 72 / 4

Multiply by 150 on both sides , we get

A = ( 150 x 72 ) / 4

On simplifying , we get

A = 2,700 meters

Therefore , the value of A is 2,700 meters

Hence , the distance is 2,700 m

Whats the supplementary angle of 109 degrees.

Answers

Answer:

Answer is 71°

Step-by-step explanation:

Two angles are said to be

supplementary angles if their

sum is 180°.

******************************************

one angle ( x ) = 109°

Let the second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 109°

=> y = 71°

So,

Supplementary angle of 109° should be 71°
