In this exercise we have to use the conditions given in the statement, that is, when adding the extreme pairs they must give the middle number, so the only number that follows this condition is:

The next year to have to same property will be 2307

are analyzing the condition given in the statement and the example we can buy as follows:

$1978 \rightarrow 19+78= 97 \\2307 \rightarrow 23+07= 30$

so the year 2307 corresponds to the conditions given in the statement.

Last summer, winky's waterpark kept track of the number of park visitors each day.

Montano1993 [528]

As per the given data 100, 150, 200, 250, 300, 350 the range of the data set is 250.

<h3>What is range?</h3>

It is defined as the difference between the maximum value in the data set to the minimum value in the data set.

We have:

Last summer, Winky's watermark kept track of the number of park visitors each day.

The data given:

100, 150, 200, 250, 300, 350

As we know range is a statistical measure which is the difference between maximum and minimum value.

Range = maximum value in data set—minimum value in data set

Range = 350 - 100 = 250

Thus, as per the given data 100, 150, 200, 250, 300, 350 the range of the data set is 250.

For the first 30 km, the bicyclist rode with a speed of v km/hour. For the remaining 17 km he rode with a speed which was 2 km/h

damaskus [11]

Answer:

t= 2.52 hours

Step-by-step explanation:

It is given that for first 30 km, the speed of bicyclist is v km/hour

time taken to cover first 30 km is given by

$t_{1} =\frac{30}{v}$ ( $time=\frac{distance}{speed}$ )

for next 17 km the speed of bicyclist is 2 km/hour greater than his original speed

so the speed to cover next 17 km = v+2

time taken to cover next 17 km is given by

$t_{2} =\frac{17}{v+2}$

now total time t spent by the bicyclist to cover entire trip is given by

$t=t_{1} +t_{2}$

$t=\frac{30}{v} +\frac{17}{v+2}$

now if v=18 , we have

$t=\frac{30}{18} +\frac{17}{20}$

now to add fractions we make the denominator same

Hence we will find the LCM of 18 and 20

LCM of 18 and 20 = 180

now we need to make both the denominator equal to 180

$t=\frac{30(10)}{18(10)} +\frac{17(9)}{20(9)}$ $t=\frac{300}{180} +\frac{153}{180} =\frac{300+153}{180}$

$t=\frac{453}{180} =2.52$ hours (approx)

Expand and simplify (x+5)(x+2)

Savatey [412]

Answer= x²+7x+10

When we want to expand expressions such as this, the FOIL method helps us remember what exactly to do. FOIL stands for

F:First
O:Outer
I:Inner
L:Last

So, given the expression (x+5)(x+2), lets multiply the first two terms.

x*x=x²

now the outer two terms

x*2=2x

now the inner terms

5*x=5x

and the last terms...

5*2=10

When we combine these expressions we get:

x²+7x+10

I think this is what you meant to be answered in your question, if I have been mistaken, just comment and I'll edit my answer....

If $580 is invested in an account which earns 9% interest compounded annually, what will be the balance of the account at the en

joja [24]

The formula for compounded interest is A = P (1+r/n)^nt.
P=580
r = .09
n = 1
t = 9
<span>
To find how much the balance is at the end of nine years, plug in all of the knows into the formula.</span>
A = 1259.698 is how much the balance will be. (Rounded to 1259.70 if you round to the nearest cent).
