Answer:

Since there are 8 sections and 3 are even

We consider that 3/8

We now multiply by 120 since they said 120 times it is spun

3/8 x 120 = 45

The answer is 45.

1. 2/50

2.  1/10

Answer:

Step-by-step explanation:

Circumstance of a curcle C=2*pi*r

So if you want to find r from this equation you come up with r=C/2*pi. That's exactly what they give you in the problem.

Now you know that C= 26.69 so replacing what we know in the formula r=C/2*pi you get

r=26.69/2*3.14 =4.25

So looking at the figure you they said r=4.25

That means that the figure is has to be a circle.

Hope that makes sense.

Answer: 7/10, 7/10 and 3/10.

Step-by-step explanation:

7/10 = Between 1 and 10, the multiples of three are 3, 6, and 9. So the amount favourable outcomes is the total minus the multiples, 10-3 = 7. So 7/10.

7/10 = Between 1 and 10, the multiples of 2 are 2, 4, 6, 8, and 10. The multiples of 3 are 3, 6 and 9. That, gives 7 favourable outcomes (6 is a multiple of both but counted once) giving the probability of 7/10.

3/10 = The favourable outcome is 8 and above, so: 8, 9 and 10. There are 3 favourable outcomes which gives the probability of 3/10.

Answer:

1) = 2hrs and 30mins

2) = 130miles

Step-by-step explanation:

1) 60mi/hr, total driven 150miles

so at 120miles thats 2 hours. 30 miles is 30 minutes

60+60+30=150miles

2) 40miles/hr you drove 2 hours at 40 miles

40+40 =80miles

50miles/hr you drove 1 hour st 50 miles

40+40+50 = 130miles

Answer: 1)  2.5 hours,  2)  130 miles

Step-by-step explanation:

To solve both of these problems, let us remember the formula:

    Distance = (speed) × (time)

1)  Plug in the numbers into the formula:

    150miles = (30miles/hour) × (time)

Divide both sides by 30miles/hour to solve for time:

    150miles/(30miles/hour) = time

Simplify:

    2.5hours = time

2)  Susan's driving is broken into two parts with different speeds and time.

Solve the distance for first drive by plugging numbers into formula:

    Distance = (40miles/hour) × (2hours)

Multiply:

    Distance of first drive = 80miles

Solve for distance of second drive:

    Distance = (50miles/hour) × (1hour)

Multiply:

    Distance of second drive = 50miles

Add distance of first drive and second drive:

    80miles + 50miles = 130miles

Answer:

Step-by-step explanation:

Each package holds 24 so you would use the equation n = 24p

which means the number of lightbulbs = 24 times the number of packages

so 1 package = 24

3 packages = 72

10 packages = 240

Answer:

7 is the radius

14 is the diameter

44 is the circumference

Step-by-step explanation:

7 is the smallest number of them all so it's the radius. The diameter is double of a radius so 14 is the diameter and finally 44 is the circumference :)

Answer:

each runner ran 2.5 kilometers

Step-by-step explanation:

10÷4=2.5

The distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.

A method of dividing something into equal parts is called division. It produces a fair distribution of resources and is one of the four basic operations in mathematics.

Total distance = 10 kilometers

Total number of runners = 4

Since they all covered the same distance,

the distance = 10/4 = 2.5 kilometers

Therefore, the distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.

#SPJ2

The greatest possible length of each piece is 2 cm.

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

Three ropes of length 2 m 84 cm, 4 m 26 cm, and 7 m 10 cm are to be cut into small pieces of equal length.

We have been given the lengths of the ropes as

2 m 84 cm = 284cm

4 m 26 cm = 426cm

7 m 10 cm= 710 cm

We have to determine the greatest possible length of each equal part So that there is no wastage

So the greatest possible length of each piece will be the HCF of the length of the ropes.

⇒ 284 = 2× 142

⇒ 426 = 2 × 213

⇒ 710 = 2 × 355

Hence, the HCF of the 284, 426, and 710 is 2.

Therefore, the greatest possible length of each piece is 2 cm.

Add a nails: 65+40+45+176= The answer

660

Step-by-step explanation:

John

65s (small)

40m (medium)

45 L (large)

Susan

x small

176m

y large

From question:

Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box =Meaning same ratio

John ratio. Susan

s : m : L s : m : L

65 : 40 : 45. 13 : 8 : 9

13 : 8 : 9. x : 176 : y

x = (176/8)*13

=286

y = (176/8) * 9

= 198

Total number of nails in Susan box

= x + 176 + y

= 286 + 176 + 198

=660

Answer:

x = 5

Step-by-step explanation:

4x + 2y + z = 24

2x - 3y - z = 2

5x + y + 2z = 21

-----------------

Eliminate z

Add the 1st and 2nd eqn

4x + 2y + z = 24

2x - 3y - z = 2

----------------

6x - 1y = 26 eqn A

Multiply the 2nd eqn by 2, then add the 3rd.

4x - 6y -2z = 4

5x + y + 2z = 21

----------------

9x - 5y = 25 eqn B

---------------

Now you have 2 eqns in 2 unknowns, not 3.

Multiply eqn A by 5 and subtract eqn B.

30x - 5y = 130 eqn A times 5

9x - 5y = 25 eqn B

-------------

21x = 105

x = 5
