The figure is made up of a hemisphere and a cylinder.
What is the exact volume of the figure?
Enter your answer in the box.
Answers
Answer:
90π in^3.
Step-by-step explanation:
Total Volume = volume of cylinder + volume of the hemisphere.
= πr^2h + 1/2*4/3πr^3
= π * 3^2 * 8 + 2/3 π 3^3 ( Note the radius r = 1/2 diameter = 1/2*6 = 3)
= 72π + 18π
= 90π in^3.

james lives 4/5 miles from the libary he has already walked 3/4 of the way. How far had james walked
Answers
Answer:
600M
Step-by-step explanation:
Convert miles to meters. Then convert the fractions. 1000M divided by 5 = 200. Now times by the numerator of the fraction, which is 4. This gives you 800. Now, 3/4 of 800 = 600. as you divide by the denominator, and times by the numerator. The answer is 600M, or 0.6 Miles.

2. If √17 (square root of 17) is a side length of a square, what does that mean about the area? Explain.
3. What is a rational number? Give an example.
4. What is an irrational number? Give an example.
Estimate the value of √70 (square root of 70). Show your work and explain.
Answers
Answer:
1A: 29 units²
1B: √29 units
2, 3, 4. see below
5. between 8 and 8.5
Step-by-step explanation:
1A: Split the given square up into 4 triangles and a square in the centre. You'll get 4 triangles of sides 5 and 2, and a centre square of sides 3.
Area = 4(0.5)(5 x 2) + (3²) = 29 units²
1B: Square root your answer in 1A. √29 units
Alternatively you can use Pythagoras' theorem on one of the triangles. √(5² + 2²) = √29 units
2. The area is exactly 17 units, because the area of a square is the length of its side squared. (√17)² = 17, hence the square's area is 17 units.
3. A number that can be expressed as a fraction (includes whole numbers). E.g. 1/2, 1/7, 4
4. A number that cannot be expressed as a fraction. E.g. π, e, √3
5. Consider the closest square numbers to 70. 70 is closer to 64 than 81 (difference of 6 vs 11). Hence √70 should be closer to 8 than 9. Your answer should be between 8 and 8.5.

Carter bought a pair of shoes online for $64. He used a coupon code to get a 10% discount. The website also applied a 5% processing fee to the price after the discount. How much did Carter pay for the processing fee? Round to the nearest cent.
Answers
Answer:
$60.48
Step-by-step explanation:
Price after the discount = original price - discount
discount = 10% x 64 = $6.4
$64 - $6.4 = $57.60
processing fee = 57.60 x 5% = $2.88
Price paid = $2.88 + $57.60 = $60.48

Raja drove from A to B at an average speed of 50mph
The distance between A to B is 10 Miles
Raja took 30 minutes to drive from A to C
He drove from A to C at an average speed of 62mph
Work out Raja’s average speed as he drove from B to C
Answers
Answer:
44.7
Step-by-step explanation:
Speed = distance / time
speed from distance a to b = 50 = 10 / time
time = 10/50 = 12 minutes
Speed from a to c = 62 = distance / 30 minutes
distance = 62 x 0.5 = 31 m
diatance from b to c = 31 - 10 = 21
time = 30 - 12 = 28 minutes
speed = 21 / 28 minutes
31 / 0.47
What is the standard deviation for the data given:
{12, 13, 29, 18, 61, 35, 21}
Answers
Answer:
15.866
Step-by-step explanation:
you would first find the mean of the data set by adding all the numbers together and dividing by the number of data points given (7 in this case).
12+13+29+18+61+35+21 = 189189/7 = 27you would then use the mean to solve for the standard deviation by using the equation, σ=√Σ(x-μ)²/N.
first, subtract the mean from all the data points
12-27=-15, 13-27=-14, 29-27=2, 18-27=-9, 61-27=34, 35-27=8, 21-27=-6then, square each calculated value from above
-15²=225, -14²=196, 2²=4, 9²=81, 34²=1156, 8²=64, 6²=36then, add the squared values together
225+196+4+81+1156+64+36 = 1762you would then divide 1762 by 7 (number of data values given orginally)
1762/7 = 251.714finally, take the square root of 251.714 to find the standard deviation

Answer:
The answer is obtuse
Step-by-step explanation:
because a triangle cannot be a right or parallel or a Isosceles.
Hope this helps!:)
Answer:
The correct answer is: Isosceles.
Step-by-step explanation:
First let’s take a look at ‘Right’. Right, is determining the angle, not the side length.
’Obtuse’. Obtuse is also determinin the angle, therefore it cannot be the correct answer.
’Parallel’. It is impossible for a triangle to be parallel, meaning that there are two opposite sides, incapable of touching each other.
’Isosceles‘ for a triangle to be isosceles, it needs two sides made of equal length. This description connects with the question being asked, therefore ‘Isosceles‘ is the correct answer.
