Answer:

(5, 35) and (25, 20)

Step-by-step explanation:

The question is saying that x = minutes spent watching videos and y = minutes spent playing video games.  Gian has 45 minutes in total to spend.  The equation for Gian spending y minutes playing video games if he spent x minutes watching videos would be 45 - x, since x minutes have been taken away from Gian's 45 minutes by watching videos.  

Knowing this, if he spent 5 minutes watching videos (x) on Monday, that means he spent 40 minutes playing video games.  So, the first coordinate point would go to (5, 40).  On Tuesday, he spent 25 minutes watching videos, which would mean he spent 20 minutes playing video games.  The second coordinate point would go to (25, 20).

Yes, there is. It's 14. Hope this helps.

Answer:

First break it down

42= 40 & 2

27= 20 & 7

Then times 40 & 20 to get 800

20 x 2 to get 40

40 x 7 to get 280

7 x 2 to get 14

Now add them all together.

800 40 1080

+280 +14 + 54

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

1080 + 54 = 1134

The expression for the perimeter of the rectangle is 63.2x - 14.6.

Given that,

We Know that

Perimeter of the rectangle is

[tex]= 2(l+w)\\\\= 2 (7x + 3.1 + 24.6x - 10.4)\\\\= 2(31.6x - 7.3)[/tex]

= 63.2x - 14.6

Here the above formula should be applied for measuring the perimeter of the rectangle.

Therefore we can conclude that The expression for the perimeter of the rectangle is 63.2x - 14.6.

Answer:

24.3

Step-by-step explanation:

First you solve the sides:

24.6-10.4 =14.2

7+3.1=10.1

After that ,you will add because perimeter is adding up the side lengths of various shapes.

14.2+10.1=24.3

Answer:

5m

Step-by-step explanation:

Applying Pythagoras theorem:

a² + b² = c² (where a is base length, b is the height and c is the hypotenuse of the right triangle)

3² + 4² = c²

c² = 9 + 16 = 25

c = x = [tex]\sqrt{25}[/tex] = 5

∴ x = 5m

Assigning answers to statements about square numbers, whether it is always true, sometimes true or never true:

The term square numbers refers to numbers which are gotten when an integer multiplies itself. It is also called a perfect square. This number type is important in the field of mathematics and always applied.

Example of perfect squares are 4, 9, 16, 25, 36, 49, 64. 91, 100 and so on.

A perfect square will never have 2, 7, 3, or 8 as the last digit hence we can say that:

Answer: slope (m) = - 9/5

Step-by-step explanation:

Find two points = (-4,5) (1, -4)

The slope going uphill is positive and downhill is negative.

Slope m = (y-y)/(x-x)

(5- -4)/-4-1 = - 9/5

Also, start in one point go straight up or down counting, and then go left or right to the other point counting.

Answer:

  27 square units

Step-by-step explanation:

The height is measured perpendicular to the base, so it is convenient to use a base such that the height is easily found. Here, the vertical line is a suitable base, as the height is the horizontal distance from that to the opposite vertex.

  A = 1/2bh = 1/2(9)(6) = 27 . . . . square units = triangle area

Answer:

a + 4(n-1)

Step-by-step explanation:

The first term is a+4, the second term is a+8, the third term is a+12, etc.

A common theme that we can notice is that we add 4 for each term. For example, the second term (t₂) equals t₁+4, the third term equals t₂+4 (as a+4+4 = a+8), and so on. Another way of writing this is that we multiply 4 by (term number - 1) and add that to a. We can write this as

4 * (n-1) + a

(x-6)^2 + (y+3)^2= 144

Step-by-step explanation:

The equation of a circle can be written in the form

(x-h) ^2 + (y-k) ^2 = r^2 where (h,k) is the center and r is the radius

( x-6) ^2 + ( y--3)^2 = 12^2

Answer:

  (c)  16.5 cm^2

Step-by-step explanation:

The area of each triangle is given by the formula ...

  A = 1/2bh

Smaller triangle area = (1/2)(2 cm)(6 cm) = 6 cm^2

Larger triangle area = (1/2)(5 cm)(9 cm) = 22.5 cm^2

The difference in area is ...

  22.5 cm^2 -6 cm^2 = 16.5 cm^2
