tomas is planning out a rail trail using a map with a marked grid. The head of the trail, which has an information kiosk, is located at (3, 0). He moves 1 unit east and 3 units north and places a pin at (4, 3) to represent the location of another information kiosk. He continues to move 1 unit east and 3 units north twelve more times, placing a pin each time. Where will the last pin be placed?

theres a picture aswell!

Answers

Kiosks only occur when the y-coordinate is a multiple of 3. The closest to the 40 units of northern land would be at 39. 39 divided by 3 would mean Tomas placed an additional 13 kiosks after the first. With the x-coordinate incrementing 1 unit east each time, the x-coordinate of the last kiosk endpoint is 3+13 or 16. Thus the foot of the trail ends at (16,39).

Answer:

The last pin will be placed at (16,39).

An secondary school have 250 students 30% in the First grade secondary and 35% Second grade secondary.
how many students in the Third grade are there​

Answers

Answer:

Third grade secondary = 87 students

Step-by-step explanation:

First grade = 30/100 x 250 = 75 students

Second grade = 35/100 x 250 = 87.5 rounded off to 88 students. Because students can't be half thus can't be in decimal. So round off to the nearest whole number.

Third grade = 250 - 88 - 75 = 87 students

2. 1131

3. 490.1

4. 1809.6

Step-by-step explanation:

A=2πrh+2πr2

Answer:

1.  SA = 216π cm² ≈ 678.24cm²

2. SA = 360π ft²≈ 1130.40ft²

3. SA = 156π yd² ≈ 489.84yd²

4. SA = 576π m² ≈ 1808.64 m²

Step-by-step explanation:

SA of a cylinder = 2πrh + 2πr²

1.  r = diameter ÷ 2

  r = 12/2 = 6

   SA = 2π(6)(12) + 2π(6)²

   SA = 144π + 72π

   SA = 216π ≈ 678.24

2. r = 19/2 = 9

   SA = 2π(9)(11) + 2π(9)²

   SA = 198π + 162π

   SA = 360π ≈ 1130.40

3.  SA = 2π(6)(7) + 2π(6)²

    SA = 84π + 72π

    SA = 156π ≈ 489.84

4. r = 24/2 = 12

    SA = 2π(12)(12) + 2π(12)²

    SA = 288π + 288π

    SA = 576π ≈ 1808.64

Answers

Answer:

7282

Step-by-step explanation:

To answer this use PEMDAS

First, we need to multiply: 76 x 94 = 7144

Then we add: 7144 + 138 = 7282

Answer:

\(\boxed{7282}\)

Step-by-step explanation:

Using PEMDAS rule:

P = Parentheses

E = Exponents

M = Multiplication

D = Division

A = Addition

S = Subtraction

Now, let's solve:

\( \mathsf{138 + 76 \times 94}\)

Multiply the numbers

\( \mathsf{ = 138 + 7144}\)

Add the numbers

How did you decide where to place your line of best fit? Describe your reasoning.Based on your data,

Answers

Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.

So basically the units are counting up by 5.

The x axis is age in years and y axis is the number of US states named in 60 seconds.

Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.

(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

Pls help, 20 points! A number cube is rolled d360 times, and the results are recorded as follows: 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes. What is the experimental probability of rolling a 2 or a 3?

It would help if you could put the answer in decimal form but you don't have to :D

Answers

Answer:

The experimental probability of rolling a 2 or a 3 is 2/9 or 0.222222 (go as long as you like :D)

Step-by-step explanation:

Total number of times cube roller = T = 360,

we have 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes

The probability of rolling a 2 is,

since we get 31 twos out of 360 rolls,

P(2) = 31/360

The probability of rolling a 3 is,

since we get 49 threes out of 360 rolls,

P(3) = 49/360

the experimental probability of rolling a 2 or a 3 is the sum of these two,

so,

P(2 or 3) = P(2) + P(3) = 31/360 + 49/360 = 80/360 = 2/9

P(2 or 3) = 2/9

In decimal form, P(2 or 3) = 0.2222222

The experimental probability of rolling a 2 or a 3 is 2/9 or (0.2222) .

The number of times a 2 or a 3 was rolled is the sum of the occurrences of twos and threes,

P(2) = 31

P(3) = 49

P(2) + P(3) = 31 + 49 = 80.

The total number of rolls is given as 360.

Now, calculate the experimental probability:

Experimental probability of rolling a 2 or a 3 = Number of times a 2 or a 3 was rolled / Total number of rolls

P(2 or 3) = 80 / 360

After simplifying the fraction:

Experimental probability of rolling a 2 or a 3 = 2/9

Therefore, the experimental probability of rolling a 2 or a 3 is 2/9.

B: 3*2=6 n=6

D: 48/8=6 n=6

∑ Hey, js1012201 ⊃

Answer:

(A) 4 = 10 - n

(B) 3 = n/2

(D) 8n = 48

Step-by-step explanation:

Given:

Select all the equations where n = 6 is a solution.

Choose 3 answers:
(A) 4 = 10 - n

(B) 3 = n/2

(C) 12 = n + 7

(D) 8n = 48

(E) 5 + n = 8

Solution:

Let's solve each answer choices to see where n = 6 is a solution:

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

(A) 4 = 10 - n

4 + n = 10 - n + n

4 + n = 10

4 + n -4 = 10 - 4

n = 6

(A) n = 6

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

(B) 3 = n/2

Multiply both sides by 2

2n/2 = 3 × 2

n = 6

(B) n = 6

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

(C) 12 = n + 7

Subtract both sides by 7

n + 7 -7 = 12 - 7

n = 5

(C) n = 5

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

(D) 8n = 48

Divide both sides by 8

8n/8 = 48/8

n = 6

(D) n = 6

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

(E) 5 + n = 8

Subtract 5 from both sides

5 - 5 + n = 8 - 5

n = 3

(E) n = 3

This question is simple. Do not worry. I will get it done for you. What we need to do here is to divide 2/3 by 6 because you have 2/3 of the salad leftover and you want to split it among 6 friends. 6/1 is the same as 6 because if you divide 6 and 1, you get 6. Hence, 2/3 / 6/1. However, we need to flip the second fraction. So, 6 is the denominator and 1 is the numerator. When we do that, the question is now a multiplication question.

2/3 x 1/6 = 2/18

However, the fraction can be simplified by dividing both sides by 2.

2/2 x 18/2 = 1/9

Hence, each friend receives 1/9 of the salad.

Tokens are put on some squares of an 8 x 8 grid to make a pattern, such as the one shown in the first diagram (without arrows.

We try to remove the tokens in a sequence of clearing steps. A clearing step consists of choosing row or a column which only contains 1 or 2 tokens and removing them. For example, we cannot initially remove all tokens from Column D. But we can clear Row 5 and then, in some later step, remove the two remaining tokens in column D.


If all the tokens in a oattern can be removed from the grid using some sequence of clearing steps, the pattern is called clearable. The pattern in the diagram is clearable because we can remove all tokens using the following sequence of 13 steps (among other possibilites) :
