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

Answer:

Step-by-step explanation:

Start box

180 = 89+42+x

180-89-42=x

49 = x

2nd box

180 = 84+58+x

180-84-58=x

38 = x

3rd box

180=74+2x

180-74=2x

106/2 = x

53 = x

4th box

180=102+2x

180-102=2x

78/2 = x

39 = x

4th box

180 = 73+81 +x

180-73-81=x

26 = x

5th box

180=2*54+x

180 - 2*54 = x

72 = x

6th box

180=62-2x

180-62=2x

118=2x

118/2=x

59 = x

7th box

180 = 2*68 + x

180-2*68=x

44 = x

Step-by-step explanation:

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.

Answer: The answer above me is correct.

Step-by-step explanation:  good luck on the quiz :)

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

Answer:

4.8% of $4,500 = $216

Answer:

C

Step-by-step explanation:

The answer is c because there is only one answer for the question.

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.

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.

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).

you 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

then, square each calculated value from above

then, add the squared values together

you would then divide 1762 by 7 (number of data values given orginally)

finally, take the square root of 251.714 to find the standard deviation

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.
