Two students, Matt and Billy , each calculated the volume of a spherical ball with a dime tee of 15 centimeters. Their work is show below

Answers

Answer 1

Answer:

Matt ;

Used diameter of the ball instead of Radius

Step-by-step explanation:

The volume of a sphere is given as :

4/3πr³

Radius, r = diameter / 2

Given that, the diameter = 15 cm ; The Radius = 15 / 2 = 7.5 cm

Matt made an error in his calculation by failing to covert the value of the diameter given to Radius.

By dividing the diameter by 2 = 15 / 2 = 7.5, we obtain the Radius, which is what Billy did in her own calculation.

Convert the improper fraction to a mixed number or a whole number to improper fraction is 50/10

Answers

Answer: Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

50/10 = 5

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (5) and multiply it by the original denominator (10). The result of that multiplication is then subtracted from the original numerator:

50 - (10 x 5) = 0

Step 3: Our mixed fraction

We've now simplified 50/10 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

5

0

10

You maybe have noticed here that our new numerator is actually 0. Since there is no remainder, we can remove the entire fraction part of this mixed number, leaving us with a final answer of:

5

1. What is the measure of angle B04?
2. What is the measure of angie BDA?
3. What is the measure of angle BCA?

Answers

Using the inscribed angle theorems, the measure of the indicated angles are:

1. m∠BOA = 30°

2. m∠BDA = 15°

3. m∠BCA = 15°

What is the Inscribed Angle Theorems?

Based on the inscribed angle theorems, the following relationships are established:

Inscribed angle = 2(measure of intersected arc)Central angle = measure of intersected arc

Given:

Intercepted arc BA = 30°

1. ∠BOA is central angle

Thus:

m∠BOA = 30° (inscribed angle theorems)

2. ∠BDA is inscribed angle.

m∠BDA = 1/2(30) = 15° (inscribed angle theorems)

3. m∠BCA = m∠BDA  = 15° (inscribed angle theorems)

2x+4=12 helppppppppppppppp​

Answers

Answer:

x=4

Step-by-step explanation:

1. 2x+4=12

2. 2x+4-4=12-4

3. 2x=8

4. 2x/2=8/2

5. x=4

Answer:

x=4

Step-by-step explanation:

2x+4=12

Step 1: subtract both sides by 4

4-4=0 and 12-4=8

Now you are left with 2x=8

Step 2: divide 2 on both sides

2/2=1x and 8/2=4

Therefore, x=4

An angle measures 150° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

         165°  and  15°

Step-by-step explanation:

x      - an angle

x - 150°     - the angle's suplementary angle

Measure of suplementery angles adds to 180°

x + x - 150° = 180°

2x = 180° + 150°

2x = 330°

 x = 330°÷2

 x = 165°

x-150° = 165° = 150° = 15°
