Which expression is equivalent to 2-2 x 22?

Answer:

[tex]y = -x + 115[/tex]

Step-by-step explanation:

Given

See attachment for graph

Required

The equation of best fit

First, we pick two corresponding points on the graph,

We have:

[tex](x_1,y_1) =(55,60)[/tex]

[tex](x_2,y_2) =(45,70)[/tex]

Calculate slope (m)

[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]

This gives:

[tex]m = \frac{70 - 60}{45 - 55}[/tex]

[tex]m = \frac{10}{-10}[/tex]

[tex]m = -1[/tex]

The equation is the calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives

[tex]y = -1(x - 55) + 60[/tex]

Open bracket

[tex]y = -x + 55 + 60[/tex]

[tex]y = -x + 115[/tex]

Answer:

$168.

Step-by-step explanation:

1 group of 7 crayon pens and 4 sketch pens = 7 x 2 + 4 x (2 + 2) = 14  + 4 x 4 = $30

Number of groups = 360/30 = 12

12 x 7 x 2 = 168

He spent $168 on the crayons.

Answer:

Hours spent for snowboarding = 1 hour 35 minutes

Step-by-step explanation:

Total hours spent for skiing and snowboarding = 3 hours

Hours spent for skiing = 1 hours 25 minutes

How long did he spend snowboarding?

Hours spent for snowboarding = Total hours spent for skiing and snowboarding - Hours spent for skiing = 1 hours 25 minutes

= 3 hours - 1 hours 25 minutes

1 hour = 60 minutes

3 hours = 180 minutes

1 hours 25 minutes = 85 minutes

3 hours - 1 hours 25 minutes

= 180 minutes - 85 minutes

= 95 minutes

95 minutes = 1 hour 35 minutes

Hours spent for snowboarding = 1 hour 35 minutes

Answer:

x² + y² = 4

Step-by-step explanation:

We need to write the standard equation of circle with , centre (0,0) and radius 2 unit . The Standard equation of the circle ⭕ is ,

=> ( x - h)² + (y -k)² = r²

=> ( x -0)² + (y-0)² = 2²

=> x² + y² = 4 .

Divide the diameter by 2 to get the radius so 400/2 = 200

C = 2 π r = 2 · π · 200 = 1256.637

Answer: The answer is b

Step-by-step explanation:

Length is a non-negative quantity. The correct statement for solution of the equation representing length of the table is given by: Option B: B. No; One of the solutions is negative. You cannot use negative values for a length of a table

The solution to this equation means values of variable x for which the function p(x) evaluates to 0.

For the given condition, we're given that:

The solution to the equation [tex](x + 1)(2x-3) = 0[/tex] (the question needs to include the 0 on right or some constant at least) will give the length of the table.

Since we know that

[tex]A \times B \implies A = 0\: \rm or\: B = 0[/tex] or both.

Thus, from [tex](x + 1)(2x-3) = 0[/tex], we get:

[tex](x + 1) = 0[/tex] or [tex](2x-3) = 0[/tex]

From the first equation, we get:

[tex](x + 1) = 0\\x = -1[/tex]

From the second equation, we get:

[tex](2x-3) = 0\\x = \dfrac{3}{2} = 1.5[/tex]

x represents the solution of the considered equation, thus, representing length of the table, as stated in the problem. Know that length can be 0 or positive, but cannot be negative. Thus, the first solution is not valid as it gives negative value for the length of the table.

Therefore, the correct statement for solution of the equation representing length of the table is given by: Option B: B. No; One of the solutions is negative. You cannot use negative values for a length of a table

Answer:

Laura needs to try 36 more times before the lock is sure to open.

Step-by-step explanation:

Alright, with a three digit lock, there are 9 possible numbers for each digit:

1, 2, 3, 4, 5, 6, 7, 8, and 9.

Since the first one is 3, lets move onto the second digit, which is prime.

Of the numbers between 1-9,

2, 3, 5, and 7 are prime.

With the last digit, it can be any number 1-9.

With all of this, there are 4 combos left for the second digit then 9 combos for the third digit. Therefore, there would be 36 possible combinations as 4 * 9 =36.

the formula is

n!/(n-k)!)k!

remember 0! = 1

so

9!/(9!-0!)9! = 9!/9! = 1

so

Answer:

h = [tex]\sqrt{55}[/tex] in

Step-by-step explanation:

A right triangle is formed by h, slant height and radius

Here the legs are h and 6 ÷ 2 = 3, hypotenuse is 8

Using Pythagoras' identity in the right triangle

h² + 3² = 8²

h² + 9 = 64 ( subtract 9 from both sides )

h² = 55 ( take the square root of both sides )

h = [tex]\sqrt{55}[/tex] in

Yellow: 12.5% chance

Answer:

So blue is 4/8 which should be as likely as not then red is 3/8 could be unlikely since it is 38 percent. then yellow is for sure unlikely since it is just 1/8

Answer:

242

Step-by-step explanation:

Circles have a total of 360°

mDBG does not include mBA or mGA

This means that mDBG = 360 - ( mBA + mGA )

mBA = 28° ( this is given )

mGA = 90° ( this is also given; it's indicated by the right angle )

Thus, mDBG = 360 - ( 28 + 90 )

28 + 90 = 118

mDBG = 360 - 118

360 - 118 = 242

Hence, mDBG = 242
