In ten-pin bowling, the highest possible score in a single game is 300. At one point in the bowling season, Fred F Stone had an average score of 177. In his next game he obtained a score of 199, which caused his average to increase to. 178. After one more game Fred would like his average to be 183. Is it possible for Fred

Answers

Let, number of games played is n and sum of their points are x.

So, [tex]177=\dfrac{x}{n}[/tex]

Now, In his next game he obtained a score of 199, which caused his average to increase to 178.

[tex]178=\dfrac{x+199}{n+1}[/tex]

Now equations are :

x = 177n ...1)

x + 199 = 178( n + 1 )

x = 178n - 21 ...2)

Solving eq 1 and 2 , we get :

x = 3717 and n = 21 .

Now, new average is 183.

Let, point scored in last game is y.

So,

[tex]183 =\dfrac{x+y}{n+1+1}\\\\183 = \dfrac{3717+y}{23}\\\\y = 183\times 23 - 3717\\\\y=492[/tex]

He required 492 points which is greater than the maximum i.e 300.

Therefore, it is not possible for Fred.

Hence, this is the required solution.

What is the slope of 12x + 3y =7

Answers

X=7/12-y/4

Ik this because I did it

Answer: y = -4x + 7/3 so the slope is -4

Step-by-step explanation:

First, we need to put the linear equation into the slope-intercept form: y = mx + b

We do this by subtracting 12x from both sides, so the equation now looks like 3y = -12x + 7. Now we divide both sides by 3 to get y alone, which gives us y = -4x + 7/3

m is always the slope, so the slope of this line is -4 or -4/1.

A roll of chain is 26 000 mm long to 2 sf. Necklaces are 540mm exactly. What is the greatest guaranteed number of necklaces that could possibly be made from the roll?

Answers

Answer:

Step-by-step explanation:

2 sf for this number means to the nearest 1 000

1 000 ÷ 2 = 500

A perfect square is a number that can be expressed as the product of an integer by itself , 169,196,225 are the perfect squares that are greater than 150 and less than 250.

What is perfect square?

A perfect square is a number that can be expressed as the product of an integer by itself or as the second exponent of an integer

greater than 150 and less than 250 perfect squares we need to find.

According to the definition of perfect square

if we multiply 13*13 we get 169 which is in between 150 and 250

if we multiply 14*14 we get 196 which is in between 150 and 250

if we multiply 15*15 we get 225 which is in between 150 and 250

So 169, 196 and 225 are perfect square numbers between 150 and 250

Answers

9514 1404 393

Answer:

see below

Step-by-step explanation:

When a figure is rotated about a center point, the central angle formed by any point on the figure and the corresponding image point will be the rotation angle. Every image point is the same distance from the center of rotation that the pre-image point was. No lengths or angles are changed: rotation is a "rigid motion", so the rotated figure is congruent with the original.

-Angle AQA' is 60 degrees.

-Triangles ABC and A'B'C' are congruent.

-Angle ABC is congruent to angle A'B'C'. (this is one of the angles of the congruent triangles)

-Segment BC is congruent to segment B'C'

-Segment AQ is congruent to segment A'Q.

Find the midpoint of segment LK with endpoints L(-2, 4) and K(5,3).

Answers

Answer: (1.5, 3.5)

Explanation:
Find the slope by using the coordinates for points L and K.

3 - 4 = -1
5 - (-2) = 7
Slope = -1/7

Then you plot your points on the graph.
But you want to half your slope to find the midpoint. So your slope would now be -0.5/3.5.

And when you follow that slope, you will plot down the coordinate (1.5, 3.5), which is the midpoint.

George is helping the manager of the local produce market expand her business by distributing flyers

George would like to earn at least $65 each day. Which of the following represents this situation,
where x is the number of flyers distributed.
a. 20 + 0.05x ≤ 65 c. 20 + 0.05x ≥ 65 c. 20 + 0.05x ≥ 65

b. 20 + 5x ≤ 65 d. 20 + 5x ≥ 65 d. 20 + 5x ≥ 65

Answers

Answer:

20 + 0.05x ≥ 65

Step-by-step explanation:

20 is by itself since thats what he earns extra per day.

Since he earns 0.05 per flyer, that means we are going to need a variable since we don't know how many flyers he passes. Let x be equal to that.

Since he wants to make at LEAST 65 we are going to use the greater than or equal to symbol since he doesn't want to make less than that.

20 + 0.05x ≥ 65
