Answer:

31/40 Hope this helps!

Step-by-step explanation:

Answer:

The answer for this question is 31/40

Answer:

(1) First pair; (2, 3), (7, 3), d₁ = 5

(2) Second pair; (-2, 5), (-2, -3), d₂ = 8

(3) Third pair; (-8, 5), (-2, 5), d₃ = 6

(4) Fourth pair; (-9, 1), (6, 1), d₄ = 15

Step-by-step explanation:

Given pair of points;

(1)  (2, 3), (7, 3)

(2) (-2, 5), (-2, -3)

(3) (-8, 5), (-2, 5)

(4) ) (-9, 1), (6, 1)

The distance between each pair of points is calculated as follows;

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

(1) first pair; (2, 3), (7, 3)

[tex]d_1 = \sqrt{(3-3)^2 + (7-2)^2} \\\\d_1 = 5[/tex]

(2) second pair; (-2, 5), (-2, -3)

[tex]d_2 = \sqrt{(-3-5)^2 + (-2-(-2))^2}\\\\d_2 = \sqrt{(-3-5)^2 + (-2+2)^2} \\\\d_2 = 8[/tex]

(3) Third pair; (-8, 5), (-2, 5)

[tex]d_3 = \sqrt{(5-5)^2 + (-2-(-8))^2}\\\\d_3 = \sqrt{(5-5)^2 + (-2+8)^2} \\\\d_3 = 6[/tex]

(4) Fourth pair; (-9, 1), (6, 1)

[tex]d_4 = \sqrt{(1-1)^2 + (6-(-9))^2}\\\\d_4 = \sqrt{(1-1)^2 + (6+9)^2} \\\\d_4 = 15[/tex]

Answer: 460 students

Step-by-step explanation:

Based on the information given in the question, let the total number of students that attend I.S. 59 be represented by x.

Since we've been given the information that 230 signed up for the school picnic which was 50% of all students in the school. Then, the students in the school will be:

= 50% of x = 230

0.5 × x = 230

0.5x = 230

x = 230/0.5

x = 460

Therefore, 460 students attend the school.

Answer:

n = 7 1/3 weeks

Step-by-step explanation:

Amount Jabari wants to save = $66

Amount he earns per week = $9

Hours worked per week = 2 hours

How many weeks will it take him to save $66?

Let

n = number of weeks will it take him to save $66

66 = 9n

n = 66/9

n = 7 3/9

n = 7 1/3 weeks

Or

n = 7.33 weeks

Answer:

C. Log base b (a) - Log base b (d)

Step-by-step explanation:

In logarithm, log means index or exponent. It can be explained with following example. Consider 2^5 = 32

here index = log = 5 so you can write the log of 32 = 5

Consider 64/16 = 4

now 64 = 2^6 and 16 = 2^4

We can write log 2(64) = 6 and log2(16)=4

Now log 64/16= log 4= 2

Also log2(64)-log2(16)=6-4=2

Therefore

Log base b (a/d) = Log base b (a) - Log base b (d)

Answer:

x=16 or any value less than 16.

Step-by-step explanation:

16x5=80 and subtract 10 you get 70. X has to equal a value that makes the whole left side of the equation "smaller" than the irght side, and 16 or any value less than that would accomplsish this.

Answer:

6m - 15 = 9m+9

Step-by-step explanation:

Looking at option b;

6m - 15 = 9m+9

Collect the like terms

6m-9m= 9 + 15

-3m = 24

Divide both sides by -3

-3m/-3 = 24/-3

m = -8

Hence the equation that has -8 as solution is 6m - 15 = 9m+9

Answer:

I did the figure

Answer:

The resultant speed = 181.3 mph

The final direction = 38.7° northeast.

Step-by-step explanation:

We need to find the component in the x-direction and in the y-direction of the speed:

For the plane:

[tex] v_{p_{x}} = 200cos(45) = 141.42 [/tex]

[tex] v_{p_{y}} = 200sin(45) = 141.42 [/tex]

For the wind we have:

[tex] v_{w_{x}} = -28 [/tex]

[tex] v_{w_{y}} = 0 [/tex]

Now, the total speed in the x-direction and  in the y-direction is:

[tex] V_{x} = v_{p_{x}} + v_{w_{x}} = 141.42 - 28 = 113.42 [/tex]

[tex] V_{y} = v_{p_{y}} + v_{w_{y}} = 141.42 [/tex]

Hence, the resultant speed is:

[tex] V = \sqrt{V_{x}^{2} + V_{y}^{2}} = \sqrt{(113.42)^{2} + (141.42)^{2}} = 181.3 mph [/tex]

Finally, the direction of the plane is:

[tex] tan(\theta) = \frac{V_{y}}{V_{x}} = \frac{141.42}{113.42} = 1.25 [/tex]

[tex] \theta = 51.3 ^{\circ} [/tex]

[tex] \theta = 90 - 51.3 = 38.7 ^{\circ} [/tex]

The plane is moving at 38.7° northeast.

The length of AC is 6.4 unit.

The correct option is C.

We have the figure from which we can say that

BD is the diameter which is

= 4.8 + 1.6

= 6.4 unit long.

Now, AC is the chord.

As, the distance between the two opposite point the the surface of circle would be same.

Then, the length of AC = length of BD

Thus, the length of AC is 6.4 unit.
