Find X and Y in the figure

Answer:

Step-by-step explanation:

  1 km/h = (1000 m)/(3600 s) = 1/3.6 m/s

Then

  225 km/h = 225(1/3.6) m/s = 62.5 m/s

In 15 seconds, that's ...

  (15 s)(62.5 m/s) = 937.5 m

The total cost equation of renting the truck if Emma were to drive mm miles will be

C=2.5m+20

Let,

C=total cost

m=number of miles

the cost function is in the form of

C=am+b

the rental company charges a fee of $2.5 per mile so a=2.5

C=2.5m+b.....................(1)

if Emma were to drive m=2 miles, the total cost would be C=25

25=2.5\c*2+b

25=5+b

25-5=b

20=b

b=20..................put it back in equation 1

C=2.5m+b

Therefore, The total cost equation of renting the truck if Emma were to drive mm miles will be C=2.5m+20

Answer:

$4

To find the amount Rae pays each month, we have to divide 48 by 12 (because there are 12 months in a year.)

48 ÷ 12 = 4.

Answer = $4.

Answer: C

Step-by-step explanation: First you have to do y-y÷x-x. So first you do 2-3 which gives you -1. Then you do 6-4 which gives you 2. Then you divide -1÷2 which gives you -0.5x. Now you know it's either C or D because it's negative. For the y-intercept, you have to plug in one of the ordered pairs to y and x using the slope-intercept form.

Answer:

[tex]N = 6[/tex] so that number becomes divisible by 3, 6 and 9.

Step-by-step explanation:

In Number Theory there is a rule of thumb which states that sum of digits of a multiple of 3 equal 3 or a multiple of three. If we know that [tex]n = 154N38[/tex], then its sum of digits is:

[tex]x = 1 + 5+4+N+3+8[/tex]

[tex]x = 21+N[/tex] (Eq. 1)

We have to determine which digits corresponds to multiples of three, there are four digits:

N = 0

[tex]x = 21+0[/tex]

[tex]x = 21[/tex] ([tex]3\times 7 = 21[/tex])

N = 3

[tex]x = 21+3[/tex]

[tex]x = 24[/tex] ([tex]3\times 8 = 24[/tex])

N = 6

[tex]x = 21+6[/tex]

[tex]x = 27[/tex] ([tex]3\times 9 = 27[/tex])

N = 9

[tex]x = 21+9[/tex]

[tex]x = 30[/tex] ([tex]3\times 10 = 30[/tex])

We get the following four distinct options: 154038, 154338, 154638, 154938. Now we find which number is divisible by 6 and 9 by factor decomposition:

[tex]154038 = 2\times 3\times 25673[/tex]

[tex]154338 =2\times 3\times 29 \times 887[/tex]

[tex]154638 = 2\times 3\times 3\times 11\times 11\times 71[/tex]

[tex]154938 = 2\times 3\times 7\times 7\times 17\times 31[/tex]

It is quite evident that [tex]N = 6[/tex] so that number becomes divisible by 3, 6 and 9.

Step-by-step explanation:

Well you first have to find the slope, which is y2-y1/x2-x1

Which is -12-7/5-5 and that equals to undefined.

So since you can't find the slope the answer should be undefined.

Step-by-step explanation:

If the sum of the two given angles is 5 + 10 = 15 then the third side cannot be larger than 15. If it is, the two given angles will fall flat on the third angle.

If the third angle is less than 5 then the sum will be less than 10 and the same thing will happen as described above.

Answer:

13

Step-by-step explanation:

Answer: 13

Step-by-step explanation:

The distance formula between two points is:

[tex]c = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Our points are as follows -

[tex]x_2 = 0, x_1 = 5\\y_2 = 8, y_1 = -4[/tex]

If we plug them in:

[tex]c = \sqrt{(0 - 5)^2 + (8 - (-4))^2}[/tex]

All we need to do now is simplify

[tex]c = \sqrt{(-5)^2 + (12)^2}[/tex]

[tex]c = \sqrt{25 + 144}[/tex]

[tex]c = \sqrt{169} = 13[/tex]

Step-by-step explanation:

Answer:

The slope of the line is 1.

Step-by-step explanation:

To solve this problem, we should use the equation for slope, which is given below:

slope = m = (y2-y1)/(x2-x1)

We can now plug in two points that are given in the table.

slope = m = (9-5)/(9-5)

We can simplify our expression for slope by first computing the subtraction inside the parentheses.

slope = m = 4/4

If we simplify the expression further by dividing the numerator by the denominator, we get:

slope = m = 1

Therefore, the correct answer is slope = 1.

Answer:

(a) 1,411,200.

(b) 302,400.

(c) 100,800.

(d) 1,008,000.

Step-by-step explanation:

Permutation is the number of ways to select k items from n distinct items in a specific order.

The formula to compute the permutation or arrangement of k items is:

[tex]^{n}P_{k}=\frac{n!}{(n-k)!}[/tex]

(a)

Compute the total number of schedules as follows:

[tex]\text{Total Number of Schedules}=\ ^{8}P_{4}\times \ ^{7}P_{4}[/tex]

                                          [tex]=\frac{8!}{(8-4)!}\times \frac{7!}{(7-4)!}\\\\=\frac{8\times 7\times 6\times 5\times 4!}{4!}\times \frac{ 7\times 6\times 5\times 4\times 3!}{3!}\\\\=(8\times 7\times 6\times 5)\times (7\times 6\times 5\times 4)\\\\=1411200[/tex]

Thus, the total number of schedules are, 1,411,200.

(b)

Compute the number of schedules that includes neither sister as follows:

If neither of sister are included in the schedule then the number of players from the team are 7 and 6 respectively.

[tex]\text{Number of Schedules without the sisters}=\ ^{7}P_{4}\times \ ^{6}P_{4}[/tex]

                                                               [tex]=\frac{7!}{(7-4)!}\times \frac{6!}{(6-4)!}\\\\=\frac{ 7\times 6\times 5\times 4\times 3!}{3!}\times \frac{ 6\times 5\times 4\times 3\times 2!}{2!}\\\\=(7\times 6\times 5\times 4)\times (6\times 5\times 4\times 3)\\\\=302400[/tex]

Thus, the number of schedules that includes neither sister is 302,400.

(c)

Compute the number of schedules including both sisters and have them playing against each other as follows:

If both the sisters are playing against each other then there will be three more places to be filled in both the teams.

And the two sisters can play in any of the 4 matches.

[tex]\text{number of schedules including} \\\text{both sisters against each other}=(\ ^{7}P_{3}\times \ ^{6}P_{3})\times 4[/tex]

                                                [tex]=[\frac{7!}{(7-3)!}\times \frac{6!}{(6-3)!}]\times 4\\\\=[\frac{ 7\times 6\times 5\times 4!}{4!}\times \frac{ 6\times 5\times 4\times 3!}{3!}]\times 4\\\\=[(7\times 6\times 5)\times (6\times 5\times 4)]\times 4\\\\=100800[/tex]

Thus, the number of schedules including both sisters and have them playing against each other is 100,800.

(d)

Compute the number of schedules including both sisters as follows:

[tex]\# \text {Schedules with the Sisters}=\text{Total}\ \#\ \text{Schedules }-\ \# \text {Schedules without the Sisters}[/tex]                                             [tex]=1411200-302400\\=1108800[/tex]

Now compute the number of schedules having the sisters playing in different matches as follows:

[tex]\text{Playing in Different Matches}=\# \text {Schedules with the Sisters}-\text{Playing together}[/tex]

                                              [tex]=1108800-100800\\=1008000[/tex]

Thus, the number of schedules including both sisters, but have them playing in different matches is 1,008,000.
