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

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

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

Answer:

-12 Fahrenheit.

Step-by-step explanation:

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.)

Answer:

7/2

Step-by-step explanation:

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
