Step-by-step explanation:
Klara picks a number. She rounds to the nearest hundred. She rounds tot the nearest thousand. She rounds the number to the nearest ten thousand. All three times, the result is the same. Which choice could be klara's number?
Answer with step-by-step explanation:
The question does not seem complete, but I'll try to make some explanations.
When you want to round a number, there are some rules.
1. If the number you are rounding is followed by 5, 6, 7, 8, 9, then round the number up, that is add 1 to it.
2. If the number you are rounding is followed by 0, 1, 2, 3, 4, then round the number down, that is add 0.
Now if given a number and you are asked to round to the nearest 100, 1 000, 10 000 and so on, then for nearest 100, count 2 numbers from the back. Whatever number you stop at, that is the number you are to round. For 1000 count 3, for 10 000 count 4 and so on.
Since Kiara is having the same value after rounding, it means she picked a number that has zeros after the 10 000th value
Let's assume she picked: 70 000
Rounding that number to nearest 100, 1000 and 10000 gives the same number which is
70 000.
what is the volume of this cube?
Answer:
1
Step-by-step explanation:
The volume of this cube is 1 cu.cm , Option B is the correct answer.
What is a cube ?A cube is a three dimensional shape having 6 square faces , all the faces are of equal length , breadth and height.
The volume of the cube is given by side * side * side
Let side = a
Then volume of the cube = a³
In the given figure all the side of the cube is given as 1 cm.
Therefore to determine the value of the volume , we will substitute in the equation
V = (1)³
Volume = 1 cu.cm
Therefore , the volume of this cube is 1 cu.cm, Option B is the correct answer.

Step-by-step explanation:
If we use both hoses, we fill the pool at 40 + 60 = 100 gallons per hour.
The volume of the pool is 60 * 300 = 45 * 400 = 18,000 gallons.
Hence, we need 18,000 / 100 = 180 hours.

Step-by-step explanation:
The first humor bookshelf in the section of a library can hold 2296, books. The bookshelf has 7 shelves. Shelves. Each shelf can hold the same number of books. How many books can each shelf hold? Write an equation to help solve this problem.
They said each shelf can hold the same number of books
And we have 7 shelves
Total number of books = 2296
Hence:
The number of books each shelf can hold = 2296 books/7 Shelves
= 328 books
Hence, each shelf can hold 328 books
An equation to solve this problem =
Number of books can be represented by x
Hence:
7x = 2296

Answer:
The answer you have clicked is correct
Step-by-step explanation:
To get x alone you need to get rid of the 4 so you subtract it from both sides
so then you have
x + 4 - 4 = 24 - 4
the fours on the left cancel out
x = 24 - 4
subtract
x = 20

Three people need to peel 1000 potatoes working together. Stacey starts at 2 PM peeling 20 potatoes per hour. Rob starts at 3 PM peeling 30 potatoes per hour, and James starts at 4 PM peeling 40 potatoes per hour. If they work continuously, at what time will the 1000 potatoes be peeled ?
Answer:
They would be done by 2 : 18 AM
Step-by-step explanation:
Key Information:
- Stacey starts at 2 PM peeling 20 potatoes per hour
- Rob starts at 3 PM peeling 30 potatoes per hour
- James starts at 4 PM peeling 40 potatoes per hour
At 5pm;
Stacy would have worked for 3 hours and would have peeled ( 3 * 20 = 60 potatoes)
Rob would have worked for 2 hours and would have peeled ( 2 * 30 = 60 potatoes)
James would have worked for an hour and would have peeled ( 1 * 40 = 40 potatoes)
Total number of potatoes peeled at 5pm = 60 + 60 + 40 = 160 potatoes
Potatoes left = 1000 - 160 = 840 potatoes.
The new peeling rate for three of them combined is (20 + 30+ 40 ) = 90 potatoes per hour.
Rate = potatoes left / time;
Time = Potatoes / Rate
Time = 840 / 90 = 9.3 hours = 9 hours 18 minutes
Total time taken = 9 hours 18 minutes + 3 hours = 12 hours 18 minutes
They would be done by 2 : 18 AM
Answer:
2:20 am
Step-by-step explanation:
Stacey's start time = 2 pm
Rate = 20 per hour
Rob start time = 3pm
Rate = 30 per hour
James start time = 4pm
Rate = 40 per hour
Number of potatoes = 1000
By 4 pm when James started :
(2 * 20) + (1 * 30) = 40 + 30 = 70
Potatoes left at 4pm = 1000 - 70 = 930 potatoes
Number of potatoes peeled per hour staring from 4 pm:
20 + 30 + 40 = 90 potatoes
Time taken to peel 930 potatoes will be :
930 / 90 = 10.333333 hours
(0.33333 * 60) = 19.9998 minutes
10.3333 hours = 10 hours 19.99998 minutes = 10 hours 20 minutes
Hence, from 4pm = 4pm + 10 hours 20 minutes = 2 : 20 a. M
Does 6(3-5w)=5(4-2w)-20w have one solution, no solution, or infinitely many solutions?
Answer:

Two or more expressions with an Equal sign is called as Equation.6(3-5w)=5(4-2w)-20w have no solution
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 6 times of three minus five w equal to five times of four minus two w minus twenty w.
6(3-5w)=5(4-2w)-20w
Apply distributive law on LHS side
6(3)-6(5w)=5(4)-5(2w)-20w
18-30w=20-10w-20w
Let us take all the variable w terms to one side
18-20=30w-10w-20w
-2=0

5(0-1) + 3y = 7(x + 1)
What is the solution?
Answer:
7x - 3y = -12
Step-by-step explanation:
5(0-1) + 3y = 7(x + 1)
using BODMAS to solve
5(-1) + 3y = 7(x + 1)
-5 + 3y = 7x + 7
7x - 3y = -5 - 7
7x - 3y = -12
Express (x + 5)^2 as a trinomial in standard form.
Answer:
Ste(x−5)2=x2−10x 25
step-by-step explanation:
The standard form of a polynomial in one variable is a sum of terms in decreasing order of degree.
For brevity, terms with negative coefficients are usually written as subtractions rather than adding the additive inverses. That is, we would write
x
2
−
3
x
+
2
rather than
x
2
+
(
−
3
)
x
+
2
In order to express
(
x
−

)
2
in standard form, we need to multiply it out, combining terms of like degree. We can use the FOIL mnemonic to help:
(
x

=

Alternatively, we can recognise a pattern and use it.
For example:

(

−

a

So we could take the second of these and put

,
b
=

to find:
(

The standard form is: [tex]x^2+10x+25[/tex].
We expand the given expression.
[tex](x + 5)^2\\=x^2+2(x)(5)+5^2\\=x^2+10x+25[/tex]
So the standard form is: [tex]x^2+10x+25[/tex].

James works in a flower shop. He will put 60 tulips in vases for a wedding. He must use the same number of tulips in each vase. The number of tulips in each vase must be greater than 1 and less than 10.
Answer: a. 1, 3, 5, 15
Step-by-step explanation:
If he needs to put an equal number of tulips in each vase he uses, the number of vases will have to be multiples of 15.
The multiples of 15 are;
1, 3, 5, and 15.
