Answer: The radius would be twelve

Step-by-step explanation:

The radius of a sphere would be 12 cm. By putting the value of volume we can find the radius of the sphere. The radius of a sphere would be 12 cm.

Step-by-step explanation:

C.P=5×1=Rs.5

S.P.=4×1=Rs.4

Loss=C.P.=S.P.

=Rs.5-Rs.4

=Re.1

loss%=loss/C.P ×100

=1/5×100%

=20%

Answer:

We have to first see that the given lengths makes a triangle or not by using a+b > c in which a,b and c are

length of sides of a triangle lets check out

16 + 21 = 37 > 28

21 + 28 = 49 > 16

16+ 28 = 44 > 21

As because the statement fits correct in the lengths given so its a triangle

So we can say that the triangle is scalene by means of measurements

but cant be a right angle as by taking the pythagorean triplet

= a^2 + b ^ 2 = c^2

lets see if a=16, b = 21 and c = 28

So a^2 + b^2

= 256 + 441

= 697

but c^2

= 28^2 = 784

As 441 =/= 784

So The triangle lengths cant be a right angled triangle

So 1/2 of possibility is the traingle acute and 1/2 of the possibilty that the triangle is obtuse

Now you can find the correct triangle on the basis of acute or obtuse angle by drawing with given length of sides of triangle

Answer:

0, 3, -6, 7

Step-by-step explanation:

Answer:

(-√3/2., -1/2)

Step-by-step explanation:

This is a reflection in the line y = -x.

So x =  1/2 becomes y = -1/2

and y = √3/2  becomes x = -√3/2.

Answer:

mean = 2

median = 2.5

Step-by-step explanation:

There are a total of 20 goals  (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)

There are 10 games, so 20/10 = 2 = mean

Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5.  So the median is 2.5

Answer:

13

Step-by-step explanation:

Once again we are looking at inscribed angles and intercepted arcs. Like stated previously an inscribed angle is equal to half its intercepted arc

That being said we want to create an equation to solve for x

The equation would be 7x + 5 = 192/2

We now solve for x

step 1 simplify

192/2=96

now we have 7x + 5 = 96

step 2 subtract 5 from each side

5 - 5 cancels out

96 - 5 = 91

7x = 91

step 3 divide each side by 7

7x/7 = x

91 / 7 = 13

we're left with x = 13

Answer:

∠A = 126°

Step-by-step explanation:

Supplementary angles are angles that add up to equal 180°

Given that ∠B = 54°, we can subtract 54° from 180°.

180° - 54° = 126°

∠A = 126°

Answer:

4ft

Step-by-step explanation:

to get the area of a square you multiply the sides together so you just find the square root of the area

Answer:

4 feet would be the legth of the squares side

Step-by-step explanation:

t16 is the squares area and the area of a square is length X width, since all the sides of a square are equal, we can just take the square root of  16 which is 4 feet.

Answer:

40

Step-by-step explanation:

Find the other missing angle, which is supplementary to 100 first.

Supplementary angels are a sum of 180

The missing angle is 180-100 = 80

Now use that to find missing angle x

All angles in the triangle have a sum of 180

180 = 60+80+x

180-60-80=x

40 = x

Answer:

Step-by-step explanation:

Sum of angles of a triangle = 180

x + (180 - 105) + (180 -140) = 180

x + 75 + 40 = 180

x = 180 -75 - 40

x = 65

Answer: 3

Step-by-step explanation:

The number of getting the black hair color clients will be 4.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of samples

Given the of the clients who had their hair cut at Tanner's salon last month, 4 clients had black hair and 12 clients had hair in other colors.

The probability is:-

P = 4 / 12

The number of clients having black color hair is calculated as:-

Number = ( 4 / 12 ) x 12

Number =  4

Therefore, there will be 4 people getting black hair colors.

Answer:

The HCF is 75

Step-by-step explanation:

Here, we want to get the highest common factors of the two numbers

To do this, we have to write the numbers as the product of their prime factors

We have;

3,000 = 2 * 2 * 2 * 3 * 5 * 5 * 5

525 = 3 * 5 * 5 * 7

now looking at this, we can see that in both numbers, we can have 3 * 5 * 5 taken out as it is common to both numbers

This represents the highest common factor of the two numbers

and that is 75

Answer:

So If you start with sinØ = .5

your calculator is programmed to always give the closest angle to 0, and that would be 30°

You probably used the cosine law to find the first angle. A suggestion is to always find the largest angle first. If that happens to be an obtuse angle, your calculator will find the correct angle.

Of course there can only be one obtuse angle in a triangle, so using the sine law for your second angle does not result in any problems

notice that in your solution 78 and 102 add up to 180 , and sin 78 = sin(180-78) = sin 102

I would have found angle S first, the largest angle always opposite the largest side.

7^2 = 5^2 + 4^2 - 2(5)(4)cosØ

40cosØ = -8

cosØ = -8/40 = -1/5

Ø = 101.537°

Now you can use the sine law and you will find the correct other angles.
