Hi there!

1:28

1.Add extra hour into first term:

[tex]5:28=6:28[/tex]

Now there is 1 hour..

2.Subtract the two terms in minute place:

[tex]52-28=24[/tex]

3.Combine the terms:

[tex]1:00+24=1:24[/tex]

Answer:

(x, y) = (-1, -11/5)

Step-by-step explanation:

Add together the two equations. We get:

(4x - 5y) + (3x + 5y) = 7 + (-14).

Simplifing we get:

7x = -7

x = -1.

So, y = -11/5

Answer:

slope:-11/5

y-intercept : (0, 3/5)

Answer: complementary

Step-by-step explanation:

The diagram of x + 3 and 2x are as drawn in the image attached

Given the situations: x = 1, x = 2, x = 3 and x = 4

For  x + 3

x = 1, x+3 = 4

x = 2, x+3 = 5

x = 3, x+3 = 6

x = 4, x+3 = 7

For  2x

x = 1, 2x = 2

x = 2, 2x = 4

x = 3, 2x = 6

x = 4, 2x = 8

You will use the values of x and y = x+3, and the values of x and y = 2x to draw the diagram of the lines as shown in the attached image

Answer:

[tex]1134yd^3[/tex]

Step-by-step explanation:

Right Triangular Prism

V = LWH

L = 6yd

W = 21yd

H = 9yd

____________________

Follow the volume formula, and multiply the length by width and height together.

V = LWH

V = (6)(21)(9)

V = 1134yd^3

Answer: the answer is 4.

Step-by-step explanation:

I got my answer by simply by “doing to one side you do to the other” in that case you going to divide 5x by 5x then on the other side your going to do the same which gets you 4. Hope this helps.

The percent of scores with the indicated ranges found using their z-scores and the z-table are as follows;

a) The percentage of scores less than 40 = 0.272%

b) Percentage of scores that are at least 72 = 21.77%

c) The percentage of scores that are between 60 and 85 = 69.905%

A z-score is an indication of the location of a score on the normal distribution curve.

The distribution of the scores on the exam = Normal distribution

The mean of the scores, μ = 65

The standard deviation, σ = 9

a) The z-score can be found by using the formula;

[tex]z = \dfrac{x - \mu}{\sigma}[/tex]

Which indicates that when x = 40 we get;

[tex]z = \dfrac{40 - 65}{9}\approx -2.\overline 7[/tex]

b) The percentage of scores that are at least 72, consists of scores that are from 72 and above;

The z-score of 72 is found as follows;

[tex]z = \dfrac{72 - 65}{9} =0.\overline 7[/tex]

From the z-score table, we get;

p(z ≥ 0.[tex]\overline 7[/tex]) = 1 - p(z ≤ 0.[tex]\overline 7[/tex])  = 1 - 0.78230 = 0.2177

c) The percentage of scares that are between 60 and 80 is found as follows;

The required percentage is; p(60 ≤ x ≤ 85)

The z-score of 60 is;  [tex]z = \dfrac{60 - 65}{9} = -0.\overline 5[/tex]

The values to the left of the z-score for 60 from the z-table is therefore p(z ≤ -0.[tex]\overline 5[/tex]) = 0.28774

The z-score of 85 is;  [tex]z = \dfrac{85 - 65}{9} = 2.\overline 2[/tex]

From the z-table, we get p(z ≤ 2.[tex]\overline 2[/tex]) = 0.98679

Answer:

10 ways

Step-by-step explanation:

Find out the number of ways in which 6 flags can be arranged in a row if 3 red ,2 green, and 3 yellow ?

The above question can be calculated as:

= 6!/(3! × 2! × 3!)

= 720 /(6 × 2 × 6)

= 720/(72)

= 10 ways

Answer:

d = 9

Step-by-step explanation:

d = [tex]\sqrt{(-5 - 5)^{2} + (10 - 1)^{2} }[/tex]

d = [tex]\sqrt{(0) + (9)^{2} }[/tex]

d = [tex]\sqrt{0 + 81}[/tex]

d = [tex]\sqrt{81}[/tex]

Step-by-step explanation:

Answer:

y= -1/2x+2

Step-by-step explanation: Our "y-intercept" (where x = 0) acts as the foundation of our function here.

We can extrapolate from what we have here...if x is 0, y is going to be 2.

So, we start at 2 for y, and every time we decrease x by 2, y increases by 1.

If we decrease x by just 1, y increases by ½.

This also goes in the opposite direction. Increase x by 1, decrease y by ½.

We can write the change in y as -½x.

That change is being added to our original value of 4, of course.

Answer:

f(10) = 93

Step-by-step explanation:

Substitute the value 10 into the equation.

f(10) = 9(10) + 3

       = 90 + 3

       = 93

Answer:

4.5 ft

Step-by-step explanation:

Let us assume the height of the taller brother be x

And, the height of the shorter brother be y

Now according to the question

x + y = 10.33

x - y = 0.833

Now solve these two equations

2x = 11.666

x = 5.833

y = 10.33 - 5.83

= 4.5 ft
