Two numbers, both greater than 23, have HCF 23 and LCM 644. The sum of the numbers is:
Answer: 253
Step-by-step explanation:
First, we have two numbers A and B.
We know that all numbers can be written as a product of prime numbers.
And the HCF of A and B is 23
Then we can write:
A = 23*a
B = 23*b
(remember that 23 is a prime number)
Where a and b are larger than 1.
Now we know that the least common multiple between them is 644.
Notice that the primes that conform a can not be the same as the ones for b, because in that case, the HCF would not be 23.
Now to find a and b we can compute:
644/23 = 28.
28 = a*b
Now let's write 28 as a product of prime numbers:
a*b = 28 = 4*7 = 2*2*7
Then we can define:
a = 2*2
b = 7.
Our two numbers are:
A = 23*2*2 = 92
B = 23*7 = 161
A + B = 92 + 161 = 253
The sum of the two numbers would be:
253
Assume the two numbers be [tex]x[/tex] and [tex]y[/tex]
Given that,
HCF of [tex]x[/tex] and [tex]y[/tex] = 23
so,
The numbers could be written as:
23[tex]x[/tex] and 23[tex]y[/tex]
We know that,
LCM of 23[tex]x[/tex] and 23[tex]y[/tex] = 644
We also know that,
LCM × HCF = The product of two numbers
∵ 644 × 23 = 23[tex]x[/tex] × 23[tex]y[/tex]
So, by solving them we get;
14812/529 = [tex]x[/tex] × [tex]y[/tex]
∵ [tex]x[/tex] × [tex]y[/tex] = 28
If we prime factorize 28, we get
28 = 2 × 2 × 7
This gives us,
[tex]x =[/tex]23 × 2 × 2 = 92
[tex]y =[/tex] 23 × 7 = 161
Thus, the sum of the two numbers = 92 + 161 = 253

Mr. Anderson has 4/5 of a pizza left over and split it among his 4 children. What fraction of the pizza did each child get? * 11 points 1/5 2/3 16/5 16/20
Answer:
The answer is 1/5
Step-by-step explanation: Turn 4 in to a fraction (4/1) and take 4/5 then flip the the 4/1 fraction (1/4) and multiply it by 4/5. 4/5*1/4=4/20 simplify it 1/5. Hope this helped!

Jill can run 20 miles in
three hours at a steady
rate. How many minutes
will it take her to run
five miles?
Answer:
45 minutes
Step-by-step explanation:
Change 3 hours to minutes
1 hours = 60 minutes
3 hours = 180 minutes
Using proportions
20 miles 5 miles
------------- = ----------------
180 minutes x minutes
Using cross products
20x = 5* 180
20x =900
Divide each side by 20
20x/20x = 900/20
x =45
45 minutes
Answer: 45 minutes
Step-by-step explanation: 20 miles in 180 minutes, 5 miles is 1/4 of 20 miles so you divide 180 by 4 which gives you 45
The sum of 2 numbers is 25. The sum of their reciprocals os 1/4. Determine the two numbers.
Answer:
5, and 20
Step-by-step explanation:
5+20=25
reciprocal of 5 is 1/5 and reciprocal of 20 is 1/20 so 1/5=4/20 and 4/20 + 1/20 = 5/20. 5/20 = 1/4

Is 4x + 9 equivalent to 2(2x+5) -1?
Answer: Yes!
Step-by-step explanation:
1. So you have: 4x+9 and 2(2x+5)-1
2. Simplify the 2nd expression: 2(2x+5) -1 = 4x + 10 - 1 = 4x+9
4x+9 = 4x+9
Answer:
Yes
Step-by-step explanation:
Set them equal to each other to see. If they are, then you should come out with the answer 0 = 0.
4x + 9 = 2(2x + 5) - 1
4x + 9 = 4x + 10 - 1
0 = 0

When do you use the divergence test, comparison test, p test, geometric, integral, comparison, limit comparison, and alternating series?
Step-by-step explanation:
Divergence Test: use this when the limit as n approaches infinity of a sequence isn't 0.
If lim(n→∞) an ≠ 0, then an diverges.
(Note this only tests divergence, not convergence.)
P Test: use this when the series is a p-series.
For an = 1 / nᵖ, if p > 1, then the series converges. Otherwise, it diverges.
Geometric Test: use this when the series is a geometric series.
For an = a₁ (r)ⁿ, if -1 < r < 1, then the series converges. Otherwise, it diverges.
Integral Test: use this when the sequence can be easily integrated.
If ∫₁°° f(x) dx converges, then ∑₁°° f(n) converges.
If ∫₁°° f(x) dx diverges, then ∑₁°° f(n) diverges.
Comparison Test: use this when a sequence is similar to a p-series or a geometric series.
If bn > an and bn converges, then an converges.
If bn < an and bn diverges, then an diverges.
Otherwise, inconclusive.
Limit Comparison Test: use this when comparison test is inconclusive.
If an ≥ 0 and bn > 0, and lim(n→∞) an/bn > 0 and finite, then an and bn either both converge or both diverge.
Alternating Series Test: use this when the series is alternating. This usually includes (-1)ⁿ or (-1)ⁿ⁺¹, but might use trig functions instead.
If an = (-1)ⁿ bn or (-1)ⁿ⁺¹ bn, where bn ≥ 0, and if lim(n→∞) bn = 0, and bn is decreasing, then an converges.
(Notice this only tests for convergence, not divergence.)
