Step-by-step explanation:

Answer 2

Answer:

1.) B.) 30

2.) D.) 2.38

Step-by-step explanation:

1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.

2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:

Start: Year 1: Year 2: Year 3: Year 4:

$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

(Please tell me if they are wrong is I can fix them, other wise, have a nice day!)

Bill rented a truck for one day. There was a base fee of $16.99, and there was an additional charge of 92 cents for each mile driven. Bill had to pay $185.35 when he returned the truck. For how many miles did he drive the truck? miles

Answers

Answer:

He paid $18 of which $15.95 was

the flat fee.

18.00

- 15.95

---------

$2.05 is the amount paid for mileage.

This is 205 cents for mileage

at 71 cents per mile. Divide

205 by 71 to get the miles driven.

205/71 = 2.9 miles.

Answers

Answer:

no solution

Step-by-step explanation:

x²-4 is (x+2)(x-2), which is your least common multiplier

So first, eliminate the denominators by multiplying all terms by (x+2)(x-2)

(x+2)(x-2)/(x-2) + (6x)(x+2)(x-2)/(x+2)(x-2) = 3(x+2)(x-2)/(x+2)

Then simplify

(x+2) + (6x) = 3(x-2)

combine the variables, and expand the right side of the equation

7x + 2 = 3x - 6

Subtract 2 from both sides

7x = 3x - 8

Substract 3x from both sides

4x = -8

Divide both sides by 4

x = -2

Although x = -2, the final answer is undefined.

Because if you plug x = -2 back into the equation, you would get...

for example, 3/(x+2) will become 3/(-2+2), which is 1/0

it is not possible to divide by 0

anything divided by 0 is undefined, therefore this equation has no solution.

write 34 as a product of its prime factors. PLEASE HELP I NEED TO TURN IT IN IN % MINUTES

Answers

Answer: Down below

Step-by-step explanation: First of all, as 34 is an even number, so it must be divisible by smallest prime 2.

Thus, 2 must be a factor of 34.

Now, look for number obtained on dividing 34 by 2 i.e.

34÷2=17.

So, 17 is our new number.

Now, look for factors/divisors of 17, which are precisely 1 and 17 i.e. 17 is itself a prime.

This implies only factors possible for 34 are 2 and 17.

Thus ,34 can be written as product of prime numbers 2 and 17 as 34=2×17.

Key idea. Given any number, divide it by smallest divisible prime and look for the number obtained on division.

Now, repeat the process for the number obtained.

If no division by a smaller prime than that number is possible, then our number is itself a prime.

30 flags in 3 3/4 that’s the whole question?

A flagpole and a model flag pole have a scale factor of 1 in.= 4 ft. If the model pole measures 12 inches, how tall is the actual pole?

Answers

Answer:

[tex]48\ \text{feet}[/tex]

Step-by-step explanation:

[tex]1\ \text{inch}[/tex] of the model is [tex]4\ \text{feet}[/tex] of the actual pole.

Here, the pole which is present in the model measures [tex]12\ \text{inches}[/tex], so

[tex]12\ \text{inches}[/tex] of the model will be [tex](12\times 4)\ \text{feet}=48\ \text{feet}[/tex]

Hence, the actual pole will be [tex]\boldsymbol{48\ \text{feet}}[/tex] tall.

You are at Coney Island Amusement Park, and burgers
cost $5 and hot dogs cost $3. You and your friends
spend $45. This is modelled by the equation
5b + 3h= 45.
Is the solution (2, 5) a viable solution?
show your work to the left]

Answers

Answer: No, the ordered pair (2,5) is not a viable solution

===========================================================

Explanation:

(2,5) means that b = 2 and h = 5

I'm assuming each ordered pair is of the form (b,h) where b comes first, since b is before h in the alphabet.

So if b = 2 and h = 5, then we can replace each letter with those numbers to get the following:

5b + 3h = 45

5*2 + 3h = 45 ..... b replaced with 2

5*2 + 3*5 = 45 ..... h replaced with 5

10 + 15 = 45

25 = 45

We don't get the same number on both sides, so (b,h) = (2,5) is not a solution.

--------------

Put another way:

If b = 2 and h = 5, this means you bought 2 burgers and 5 hot dogs

1 burger = $5

2 burgers = 2*5 = $10

1 hot dog = $3

5 hot dogs = 5*3 = $15

total amount spent = $10 + $15 = $25

total amount spent = $25

This does not match up with the $45 total spent that we're given. So this is another way to see we don't have a solution.

Step-by-step explanation:

to understand thisyou need to know about:linear equationPEMDASgiven:[tex] \tt y = - \frac{1}{4} x+ 2[/tex]to find:x and y intercepttips and formulas:to find x and y intercept we have to substitute x and y to 0 let's solve:

let's substitute x to 0 to find y intercept

y=-¼(0)+2y=2

therefore y intercept is 0

let's substitute y to 0 to find x intercept

0=(-¼)x+2(-¼)x=-2x=-2×-4x=8

therefore

x intercept is 8

and

y intercept is 2

explanation of the graph

you can clearly see that the red line crosses x and y axis to (8,0) and (0,2) respectively

therefore

x intercept is 8

What is the outlier in the following data set:
15,11,10,8,9,1,8,7,5,4,2,3, and 37?

Answers

Step-by-step explanation:

The steps to find an outlier:

1. Put the data in numerical order.

2. Find the median.

3. Find the medians for the top and bottom parts of the data. This divides the data into 4 equal parts.

The median with the smallest value is called Q1. The median for all the values - usually just called the median is also called Q2. The median with the largest value is Q3.

4. Subtract...Q3 - Q1. This value is the InterQuartileRange or IQR. Remember that the range means taking the largest minus the smallest. This is a special range having to do with the quartiles.

5. Multiply...1.5 * IQR

6. Take your answer from #5 and do 2 things with it. A). Subtract it from Q1 and B) Additional to Q3.

7. Look at all your data points. If any are SMALLER than Q1 - 1.5 *IQR, they are outliers. If any are LARGER than Q3 + 1.5 *IQR, they are also outliers.

For your data....the median, Q2 is

(43+38)/2 = 40.5.

Q1 = (30+26)/2 = 28.

Q3 = (54+52)/2 = 53

The IQR is 53 - 28 = 25

1.5 * IQR = 37.5

Q1 - 37.5 = 28 - 37.5 = -9.5. There is no data value less than -9.5.

Q3 + 37.5 = 53 + 37.5 = 90.5. there is no data value greater than 90.5.

My conclusion is that there are no outliers in this data.

I hope this helps!
