The junior senator can work his way through

senior senator can work his way through a
bureaucratic labyrinth in 30 minutes.
Working together, how many minutes would
it take them to work their way through 12
bureaucratic labyrinths?

Answers

-- Working together, they work through (1/50 + 1/30) of a labyrinth in 1 minute.

-- That's 1/18.75 of a labyrinth each minute.

-- So it takes them 18.75 minutes to work through 1 labyrinth together.

-- To work their way through 12 labyrinths, working together, would take them

(12 x 18.75 minutes) = 225 minutes.

The entry fee for a charity event is $15 per pair of people. The fee can be
paid in cash or by collecting and turning in soda can tabs. Every 10 tabs
collected earns $0.01.
Brian and Eva are collecting tabs to pay their entry fee. So far, Eva has
collected 7,100 tabs and Brian has collected 1,300 tabs. What is the
least number of tabs they must still collect in order to have enough to
pay the entry fee?

Answers

Answer:

660

Step-by-step explanation:

First, to find out how much money they have collected so far, you need to add 7100 + 1300 which is 8400. 8400= $8.40. So now you know that they have collected 8.40, you need to subtract 1500-840 which = 660

1. 2 + x = 3

2. 3x = 15

3. 2/x = 10

4. x − 7 = 12

Answers

Answer:

2

Step-by-step explanation:

3x=15

divide both sides by 3

x=5

Answer: 2. 3x = 15

Step-by-step explanation:

3x=15

divide the 3 out on both sides

so 3/3 and 15/3

and you are left with

x=5

1.) x=1

3.)x=1/5

4/)x=19

So number two is the correct answer.

Answers

Answer:

.

Step-by-step explanation:     The first answer is c. 7+3w, because the puppy already weighs 7 ounces. Since the puppy didn't end up losing those pounds, then you would add instead of subtract. Since the puppy gains 3 ounces a week, you would multiply the 3 ounces by the number of weeks that pass by. So, if one week passes, the puppy gains three ounces. Add that to the original 7 ounces, then after one week, the puppy weighs 10 ounces.

The second answer would be a. 22 ounces, because if you use the previous formula (x=7+3w), then you would plug 5 in for w. This would give you 7+3(5). 3x5=15 and 15+7=22. therefore, x=22 ounces.

Answer:

7)c, 8)a

Step-by-step explanation:

since it is originally 7 oz, and grows 3 ounces a week, it would be 7+3w.

Substitutions would be 7+3(5) = 7+15 = 22 oz

pls help I will mark as brainliest

Answers

Answer 10

Step-by-step explanation:

We need to first place the numbers in order from least to greatest.

5, 8, 10, 10, 15, 18, 23.

Now we find the median. The median is 10 (I put the ten in brackets so you know which one I'm talking about).

5, 8, 10, [10] , 15, 18, 23

Now we take out the median.

5, 8, 10, 15, 18, 23

Now we find the median of the lower portion. I put the lower portion in brackets so you could see it better.

[5, 8, 10,] 15, 18, 23

The median of the lower portion is 8.

Now we find the median of the upper portion. I put in brackets so you could see it better.

5, 8, 10, [15, 18, 23]

The median of the upper portion is 18.

Now all we have to do is find the difference between the two numbers.

18-8=10 10 is the IQR

Hope this helps and it wasn't very confusing.

Answer:

10

Step-by-step explanation:

Find the median:

(5, 8, 10, 10, 15, 18, 23)

Then, find the medians between the median and the sides.

Last, find the difference between Q3 and Q1,

Sue had 5 identical bags of candy to share with the crew. Twenty-five pieces of candy disappeared. Ted had 4 bags with the same amount of candies. He mysteriously found 10 additional pieces. Now Sue and Ted have an equal number of candies. How many pieces of candy originally came in each bag?

Answers

Answer:

Each bag originally had 35 pieces of candy

Step-by-step explanation:

Since the bags are identical, Let them Number of candies in each bag sue had be x. Thus, she had 5x candies. Since she lost 25 pieces, then she now has;

5x - 25 candies left.

We are told that Ted had 4 bags with the same number of candies like Sue had. Thus, he has 4x candies.

He mysteriously found 10 additional pieces. Total Ted now has is;. 4x + 10

Finally, we are told that Sue and Ted now have an equal number of candies.

Thus;

5x - 25 = 4x + 10

Rearranging, we have;

5x - 4x = 25 + 10

x = 35

Thus, each bag originally had 35 pieces of candy

sebuah topi berbentuk kerucut dengan panjang diameter 18 cm dan tinggi topi tersebut 20cm berapakah volume nya​

Answers

Answer:

The area of the cone is "1,695.6 cm³".

Step-by-step explanation:

The given values are:

Diameter of cone,

d = 18 cm

then,

Radius,

r = [tex]\frac{d}{2}[/tex]

 = [tex]\frac{18}{2}[/tex]

 = [tex]9 \ cm[/tex]

Height,

h = 20 cm

As we know,

⇒  Area of a cone = [tex]\frac{1}{3} \pi r^2 h[/tex]

On substituting the given values in the above formula, we get

⇒                            = [tex]\frac{1}{3}\times 3.14\times (9)^2\times 20[/tex]

⇒                            = [tex]\frac{1}{3}\times 3.14\times 81\times 20[/tex]

⇒                            = [tex]3.14\times 27\times 20[/tex]

⇒                            = [tex]1,695.6 \ cm^3[/tex]
