Answer:
2 x 2 x 2 x 5
Step-by-step explanation:
The first few prime numbers: {2, 3, 5, 7, 11, 13, 17, 19}
One way to start is to divide by the first prime until you can't do that any more, then try the next prime and so on until all the numbers in your list are prime.
40 = 2(20) divide 20 by 2 again
40 = 2(2)(10) divide 10 by 2 again
40 = 2(2)(2)(5) stop--all factors are prime.

9m by 40m : yes

15m by 30m : no
18m by 25m : no
Step-by-step explanation:
Essentially this question is asking us which dimensions of the rectangles would form a park that has the same area as the triangular park.
So the first step is to calculate the area of the triangular park.
The area of a triangle can be calculated using the formula, A = (bh)/2
where b = base length and h = height.
We are given the dimensions of the triangle and it appears that the height of the park is 20m while the base length is 36m
So we have A = (bh)/2
we know that b = 36 and h = 20
So area of triangular park = (36 * 20)/2
36 * 20 = 720
720 / 2 = 360
So the area of the triangular park is 360m²
Now we want to find which dimensions of a rectangle would create a park that has the same area of the triangular park, more specifically an area of 360m²
(Note that area of a rectangle is simply length times width )
The first rectangle dimensions are 40m by 9m. These dimensions would create a park with an area of 40 * 9 = 360m². This is the same as the triangular park so the answer would be yes for this one.
The second rectangle dimensions are 10m by 36m These dimensions would create a park with an area of 36 * 10 = 360m², which is also the same as the area of the triangular park meaning the answer for this one is also yes.
The third rectangle dimensions are 12m by 60m. These dimensions would create a park with an area of 60 * 12 = 720m². this is not the same as the area of the triangular park so the answer is no for this one.
The forth rectangle dimensions are 15m by 30m. These dimensions would create a park with an area of 30 * 15 = 450m², which is also not the same as the area of the triangular park meaning that the answer for this one is no.
Finally, the last rectangle dimensions are 18m by 25m. These dimensions would create a park with an area of 18 * 25 = 450m². These dimensions would also not create a park with the same area as the triangular park therefore the answer to this one is also no.

[tex]\\ \sf\longmapsto 50000(10)=500000[/tex]
1hundred=1005000hundreds
[tex]\\ \sf\longmapsto 5000(100)=500000[/tex]
The number 500,000 can be composed of in 50,000 tens and 5,000 hundred option (B) 50,000 tens and option (C) 5,000 hundreds are correct.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that a number that is:
= 500, 000
In the above number there is five zeroes
As we know,
Tens = 10 (one zero)
Hundreds = 100 (two zero)
We can write the above number as follows:
500,000 = 50,000x10 = 5,000 tens
500,000 = 5,000x100 = 5,000 tens
The number 500,000 can be composed of:
50,000 tens5,000 hundredsWhere tens mean 10 and hundreds mean 100.
Thus, the number 500,000 can be composed of in 50,000 tens and 5,000 hundred option (B) 50,000 tens and option (C) 5,000 hundreds are correct.

Given info:- Rationalisie the denominator of the following 1/(3+√7) + 1/(√7+√5) + 1/(√5+√3) + 1/(√3+1) = 1, also show that Left hand side is equal to Right hand side that means LHS = RHS.
Explanation:-
On rationalising the denominator, we get
First term: 1/(3+√7)
⇛{1/(3+√7)}×{(3-√7)/(3-√7)}
⇛{1(3-√7)}/{(3+√7)(3-√7)}
⇛(3-√7)/{(3)²-(√7)²}
⇛(3-√7)/{(3*3)-(√7*7)}
⇛(3-√7)/(9 - 7)
⇛(3-√7)/2
Second term: 1/(√7+√5)
⇛{1/√7+√5)}×{(√7-√5)/(√7-√5)}
⇛{1(√7-√5)}/{(√7+√5)(√7-√5)}
⇛(√7-√5)/{(√7)²-(√5)²}
⇛(√7-√5)/{(√7*7)-(√5*5)}
⇛(√7-√5)/(7-5)
⇛(√7-√5)/2
Third term: 1/(√5+√3)
⇛{1/(√5+√3)}×{(√5-√3)/(√5-√3)}
⇛{1(√5-√3)}/{(√5+√3)(√5-√3)}
⇛(√5-√3}/{(5)²-(√3)²}
⇛(√5-√3)/{(√5*5)-(√3*3)}
⇛(√5-√3)/(5-3)
⇛(√5-√3)/2
Fourth term: 1/(√3+1)
⇛{1/(√3+1)}×{(√3-1)/(√3-1)}
⇛{1(√3-1)}/{(√3+1)(√3-1)}
⇛(√3-1)/{(√3)²-(1)²}
⇛(√3-1)/{(√3*3)-(1*1)}
⇛(√3-1)/3-1
⇛(√3-1)/2
Hence, LHS = 1/(3+√7) + 1/(√7+√5) + 1/(√5+√3) + 1/(√3+1)
Now, Substitute their rationalised value in expression, we get
= (3-√7)/2 + (√7-√5)/2 + (√5-√3)/2 + (√3-1)/2
Take the LCM of all the denominator 2,2,2 and 2 is "2".
= (3-√7+√7-√5+√5-√3+√3-1)/2
= (3-1)/2
= 2/2
= 1
= RHS proved.

a.2² + b.2 + c = 2
4a + 2b = 2
(- 2,2)
a.(- 2)² + b.(- 2) + c = 2
4a - 2b = 2
4a + 2b = 4a - 2b
2b + 2b = 0
4b = 0
b = 0
4a + 2b = 2
4a = 2
a = 2/4
a = 1/2
g(x) = 1/2x² + 0x + 0

The fret numbers on a string are represented by the numbers on Bass TAB. The fifth fret on your bass is represented by the number 5. If you play a standard bass guitar, you will notice that it only has four strings. E, A, D, G is the standard tuning for a four-string bass (the same as the four lowest strings on the guitar but one octave lower). Fourths are used to tune the bass strings. A 4-string will probably suffice for most styles.Therefore,

Sarah made 2 3/4 cup of lemonade she drank 1 and 1/2 cups for lunch how much lemonade does she have left
Answer:
1 1/4 cup
Step-by-step explanation:
Make the mixed fractions regular fractions by multiplying the outside number by the denominator and then adding it to the numerator. For example
2 3/4
2 * 4 = 8 + 3 = 11
2 3/4 = 11/4
You should get 3/2 for how much she drank.
Now make sure your denominators are the same. Multiply both the numerator and denominator of the amount she drank by two to get 6/4
Then subtract the fractions.
11/4 - 6/4 = 5/4
Now make that into a mixed fraction.
She has 1 1/4 cup left
