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.

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

Answer:

Good day sir

The answer is (3,7)

Step-by-step explanation:

One way is to graph the line

Another way is to do it the hard way

3x + y = 16 is y = -3x + 16

Add the original equations up and solve

2y = -x + 17

This is a start (just solve this equation) but the answer is (3,7)

Answer: -4

Step-by-step explanation: Hello! :) To get started we need to use the equation 7x+3=4x-9, First, we need to subtract 4x from both sides to get 3x+3=-9, then we need to subtract 3 on both sides to get 3x=-12, Finally, we need to divide both sides by 3 to get x = -4. So x = -4.

Hope this helps!

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.

Solve the equation and simplify

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.

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

So the measure in degrees of the smaller angle formed by the hands of the clock at 7:48 is 24 degrees

Step-by-step explanation:

At 7:48 , we have two angles formed

One formed by the hour and the other formed by the minute hand

The angle formed by the hour hand will be;

7/12 * 360 = 210 degrees

Let’s now go for the minutes hand

mathematically;

60 minutes = 360 degrees

So 48 minutes will be ;

Recall;

there are 12 hours on a clock, so each hour will be 30 degrees

So the angle for 48 minutes will be;

48/60 * 30 = 24 degrees

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.
