Lanya's house is located at (2 2/3, 7 1/3) on a map. The store where she works is located at (-1 1/3, 7 1/3). what is the distan

notka56 [123]

Answer:

Option A: 4 units is the correct answer.

Step-by-step explanation:

Given that:

Layana's house is located at ( $2\frac{2}{3}, 7\frac{1}{3}$ )

Store is located at ( $-1\frac{1}{3},7\frac{1}3}$ )

We can find distance between two points by using distance formula.

S = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

The points can also be written as;

House (8/3, 22/3)

Store (-4/3, 22/3)

Putting values in the formula.

S = $\sqrt{\frac{8}{3}-(-\frac{4}{3}))^2+(\frac{22}{3}-\frac{22}{3})^2$

S = $\sqrt(\frac{8}{3}+\frac{4}{3}+0$

S = $\sqrt{(\frac{8+4}{3})^2$

S = $\sqrt{(\frac{12}{4})^2$

S = $\sqrt{(4)^2$

S = 4 units

Hence,

Option A: 4 units is the correct answer.

Find the value of x if B is between A and C, AB = 4x – 9, BC = 3x + 5 and AC = 17.

Tasya [4]

If A,B and C lie on the same line:

4x- 9 + 3x+5 = 17

7x = 21

x = 3

A two digit number is to be formed from the digits 0,1,2,3,4 Repetition of the is allowed. find the probability that the number

ra1l [238]

<h2>Answer:</h2>

<u>Sample space</u> = {10, 11, 12, 13, 14, 20, 21, 22, 23, 24, 30, 31, 32, 33, 34, 40, 41, 42, 43, 44}

∴ n(S) = 20 .

[i] <u>Let A be the event that the number so formed is a prime number</u>.

∴ A = {11,13,23,31,41,43}

∴ n(A) = 6

So, P(A) = n(A)/n(S) = 6/20

∴ P(A) = 3/10.

[ii] <u>Let B be the event that the number so formed is a multiple of 4</u>.

∴ B = {12,20,24,32,40,44}

∴ n(B) = 6

So, P(B) = n(B)/n(S) = 6/20

∴ P(B) = 3/10.

[iii] <u>Let C be the event that the number so formed is a multiple of 11</u>.

∴ C = {11,22,33,44}

∴ n(C) = 4

So, P(C) = n(C)/n(S) = 4/20

∴ P(C) = 1/5.

Creating like bases 2to-3 and 16

AfilCa [17]

Answer:

Step-by-step explanation:

Maybe you want a suitable common denominator for 2/3 and 1/6. If so, you can observe that 3 is a factor of 6, so 6 is a suitable common denominator.

2/3 = (2/3)·(2/2) = (2·2)/(3·2) = 4/6

The equivalents, 4/6 and 1/6, share a common denominator of 6.
