A worker can load 4 pallets in 30 minutes. At that rate, how many pallets can he load in 4 hours?

Answers

8 pallets each hour so it would be 8 x 4 to find the answer. the answer is 32 pallets

Answer:

Step-by-step explanation:

1 hour = 60 minutes

Thus, 30 minutes if half an hour.

The worker can load 4 pallets every 30 minutes.

30*2=60

4*2=8

So the worker can load 8 pallets every 60 minutes, or every hour.

8*4=32

So, a worker can load 32 pallets in 4 hours.

BONUS: The worker can load 1 pallet every 7.5 minute

For lines c, d and e, m1 = 90° and m3=90°

For the given diagram and angle measures, use complete sentences to describe each pair of lines as parallel or perpendicular. In your description, include the special angle relationship between angles 1 and 3.
lines d and e
lines d and c

Answers

The relationship between angles 1 and 3 is that they are congruent, or equal to each other. they have the same measure.

Lines D and E seem to be a pair of lines that are parallel to each other, which is what makes angles 1 and 3 congruent

Lines D and C seem to be perpendicular to each other, which would make angles 1 and 3 right angles.

Answers

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.

Answers

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

Hilary is ordering a large circular pizza from her local pizza shop. She asks about the size of the pizza and is given three different values: 14 inches, 44 inches and 7 inches.

Hilary knows three measurements that are used to describe circles: radius, diameter and circumference. Which value best matches each measurement? Explain your reasoning.

Answers

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 :)

7 in is the radius
14 in is the diameter
44 in is the circumference
7 has to be the radius because the radius is half the diameter. this in turn means that the diameter must be 14. and the circumference is 44 because the circumference is the perimeter of the circle. (it has to be the largest number)

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

Answers

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.

You have the 1st one correct...
The second one is 8/10...
The 3rd is 3/10

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. What is the greatest possible length of each equal part, so that there is no wastage? How many pieces are there in total?

Answers

1 m 42 cm, there would be 10 pieces in total. i believe this is right.

The greatest possible length of each piece is 2 cm.

What is HCF?

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.

Four runners completed in a 10-kilometer relay race. Each Runner ran the same distance. What was that distance?

Answers

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.

What is division?

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.

How to solve this problem?

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.
