Maya says there are 4 hundreds in 5,467. Jenny says there are 54 hundreds in 5,467. their teacher say's they're both right. How can that be so?
Answer: See explanation
Step-by-step explanation:
They are truly both right.
Maya says there are 4 hundreds in 5,467. This is right because the place value of 4 in 5467 is 4 hundreds = 400.
Jenny says there are 54 hundreds in 5,467. This is also correct as well. The number 5467 in words is five thousand four hundred and sixty seven. 54 hundreds equals = 54 × 100 = 5400
The place value of 5 is 5000.
The place value of 4 is 400
Addition of both gives = 5000 + 400 = 5400
If we divide 5400 by 100, we would have 54. It shows that there are 54 hundreds.
Both are correct

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that;
The four options
Now,
This is because the electric field at a point in space is in the direction of the force that the electric field would exert on a positive test charge if there were a positive test charge at that point in space1. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.
Therefore, by unitary method the answer will be Lines with arrows that point outward radiate from the charge in all directions.

5. Which equation will solve the following word problem? The professor has 390 books that he wants to display in his office. Each shelf can hold 65 books. How many shelves will he need?
A)390s = 65
b)390(65) = s
c)s/390 = 65
d)390 = 65s
Answer:
[tex]65s = 390[/tex]
Step-by-step explanation:
Given
[tex]Books = 390[/tex]
[tex]Shelf = 65[/tex]
Required
Write an expression for the scenario
1 shelf can hold 65 books.
s shelves can hold 65s books.
So:
[tex]s\ shelves - 390[/tex]
Substitute 390 for s shelf
[tex]65s = 390[/tex]
suppose the distnace in feet that an object travels t seconds is given by the formula d=64t^2 how far would the object travel after 1.5 * 10^3 seconds
Answer:
The object travels 144,000,000 feet.
Step-by-step explanation:
The distance the object travel after t seconds is given by:
[tex]d(t) = 64t^2[/tex]
How far would the object travel after 1.5 * 10^3 seconds
This is d when [tex]t = 1.5 \times 10^3 = 1500[/tex], so [tex]d(1500)[/tex]
[tex]d(1500) = 64*1500^2 = 144000000[/tex]
The object travels 144,000,000 feet.

Jamil makes a drink by mixing
1 part of orange squash with 9 parts of water.
He uses 750 millilitres of orange squash.
Jamil is going to put the drink he has mixed into 1 litre bottles.
Work out the greatest number of 1 litre bottles that Jamil can completely fill.
Answer:
7 bottles
Step-by-step explanation:
first, calculate the volume of the total ammount of soloution
750ml + 9(750ml)=7500ml
then divide by 1000 to put the total into litres
7500/1000=7.5L
7.5L goes into 1L exactly 7 times with a remainder of 500ml as the bottles are required to be completely full
Amanda is a sunflower farmer. Her farm is in the shape of a parallelogram with a height measuring 13 kilometers and a base measuring 12 kilometers. What is the total land area Amanda uses?
Answer:

Step-by-step explanation:
To find the area of a rectangle you have to to base x height. Its the same with parrallograms becase most of them look like the attached image. If you simply take one of the triangles off one side and put it on the other it becomes a rectangle. This was the formula A= bh still works.
At a historical landmark, candles are used to simulate an authentic atmosphere. A volunteer is currently putting new candles in the candle holders. On the east side, he replaced candles in 24 small candle holders and 3 large candle holders, using a total of 87 candles. On the west side, he replaced the candles in 14 small candle holders and 7 large candle holders, for a total of 77 candles. How many candles does each candle holder hold?
Each small candleholder holds ____ candles, and each large one holds ____ candles
Answer:
Each small candleholder holds 3 candles, and each large one holds 5 candles.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of candles that a small candleholder holds.
y is the number of candles that a large candleholder holds.
24 small candle holders and 3 large candle holders, using a total of 87 candles.
This means that
[tex]24x + 3y = 87[/tex]
Simplifying by 3
[tex]8x + y = 29[/tex]
[tex]y = 29 - 8x[/tex]
14 small candle holders and 7 large candle holders, for a total of 77 candles.
This means that [tex]14x + 7y = 77[/tex]
Simplifying by 7
[tex]2x + y = 11[/tex]
[tex]y = 11 - 2x[/tex]
Since [tex]y = 29 - 8x[/tex]
[tex]11 - 2x = 29 - 8x[/tex]
[tex]6x = 18[/tex]
[tex]x = \frac{18}{6}[/tex]
[tex]x = 3[/tex]
[tex]y = 29 - 8x = 29 - 8*3 = 29 - 24 = 5[/tex]
Each small candleholder holds 3 candles, and each large one holds 5 candles.

Step-by-step explanation:
First, you multiply 5,500 times 3 to get 16,500, and then divide by 100 to get 165. That is how much she earned over the past three years, but it is NOT her new account balance, because you have to add 5,500 and 165, which you would get a final sum of $5,665. I hope this helps :)

Jamal needs to purchase a countertop for his kitchen. Jamal measured the countertop as 5 ft. The actual measurement is 4.5 ft. What is Jamal’s percent error?
A) 5%
B) 11%
C) 45%
D) 50%
Answer:
percent error is 11.1% (which agrees with answer B)
Step-by-step explanation:
The discrepancy (difference) between the measurement and the real length was: 5 - 4.5 = 0.5 ft
Then the percent difference is calculated as:
(difference / real value) * 100 = ( 0.5 / 4.5ft ) * 100 = 11.1%
1. JP Construction is building a rectangular children's wading pool for the local community center. The pool will be 4.5 meters wide. To meet city building code guidelines, the area of the pool must not be larger than 8 square meters. Which inequality represents the possible lengths of the wading pool, where x represents the length of the wading pool in meters?
Answer:
[tex]x\leq 1.78[/tex]
Step-by-step explanation:
We are given that
Width of pool, b=4.5 m
We have to find the inequality which represents the possible lengths of the wading pool.
Let x be the length of wading pool
We know that
Area of rectangle=[tex]length\times breadth[/tex]
According to question
Using the formula
[tex]4.5x\leq 8[/tex]
Divide by 4.5 on both sides we get
[tex]x\leq\frac{8}{4.5}[/tex]
[tex]x\leq 1.78[/tex]
