What is 1/4 of 24 solve using a tape diagram

Answers

Draw the tape diagram: a long rectangle and divide it into 4 squares in a row.
The whole rectangle represents 24 (as a whole number), you're dividing it into 4 parts because you want to know what is 1/4 of it.
Now, to find the value of each square: 24:4 = 6.
Put the number 6 in each square, and you have found your result.
1/4 of 24 is 6.

You round 1 1/8 to 1 and 9/10 to 1 (since you are estimating) and then you add 1+1+1+1, which is 4 because to find perimeter you add the lengths and the widths together.

Zulfiya earns her regular pay $7.50 per hour for up to 40 hours of work in a week. For each hour over 40 hours of work in a week, Zulfiya is paid 1.5 times her regular pay. How much does Zulfiya earn for a week in which she works 46 hours? The answer is $367.5

Please show me the way of your solution

Answers

Zulfiya get $7.5 for each hour.
If she works more than 40 hrs she gets 1.5 times her regular pay.
She works for 46 hrs.
7.5×40=300
For next six hrs she gets 1.5 times her pay i.e. 7.5×1.5=11.25 for one hr.
for 6 hrs she gets 11.25×6=67.5
For 46 hrs she earns 300+67.5= $367.5

David is the president of the his student council. When the leadership team met for the first time,he asked each person to shake everyone else's hand if there were six people at this meeting how many handshakes were made

Answers

Answer:

There will be 15 handshakes.

Step-by-step explanation:

David is the president of the his student council. He asked each person to shake everyone else's hand.

Total number of people in the meeting = 6

Let us assume that no two people shake hands if they've already shaken them once.

The first person will shake hands with 5 persons.

The second will hand shake with 4 persons.

The third will shake hands with 3 persons and so on.

So, total handshakes will be = 5+4+3+2+1 = 15

Therefore, there will be 15 handshakes.

I believe it would be 30 total handshakes because there's 6 people and they all must shake hands with 5 other people (they can't give themselves a handshake) and 5 multiplied by 6 is 30

The floor of a rectangular meeting room is the same length as the room and is 1/6 the width of the room. What is the width of the raised platform. Length is 7 1/2 and width is 6 2/5.

Answers

Length of floor = length of room = 7.5 units

Width of floor = (1)/(6) * Width of Room = (1)/(6) * (32)/(5)

⇒ Width of floor = 1.067 units

Answer:

Width of raised platform = 1(1)/(15)\text{ units} = 1.067 units

Step-by-step explanation:

We are given the following information about the room:

Lenght of room = 7(1)/(2)\text{ units}

Width of room = 6(2)/(5)\text{ units}

We are given the following information about the raised platform of meeting room.

Length of raised platform = Length of the room  =  7(1)/(2)\text{ units}

Width of the raised platform = (1)/(6) * \text{Width of the room}

=(1)/(6) * (32)/(5)

= (16)/(15) \text{ units}

=1(1)/(15)\text{ units}

= 1.067 units
