Easy

System of equations required to determine number of games and rides are x + y=12,  2.50x + 3.75y=36.25 where x represents number of games and y number of rides.

As given,

Let x represents the number of games

and y represents the number of rides

System of equation are:

x+ y=12                        ___(1)

2.50x+3.75y=36.25    ___(2)

Multiply 2.50 to (1) subtract from (2) we get,

1.25y=6.25

⇒y=5

Hence, x=12-5

               =7

Therefore, system of equations required to determine number of games and rides are x + y=12,  2.50x + 3.75y=36.25 where x represents number of games and y number of rides.

The average rate of change in temperature per week will be -5°C.

It should be noted that from the information, the temperature of a city changed by a total of -20 over a 4 week time span.

Therefore, let the average rate of change per week be illustrated as x

Therefore, the average rate of change in temperature per week will be:

= Total change in temperature / Number of weeks

= -20 / 4.

= -5

Therefore, the average rate of change in temperature per week will be -5°C.

Answer:

24 hours/day

Step-by-step explanation:

We need to know about mixed fraction to solve this problem. Natasha used approximately 4 cups of ingredients.

A mixed fraction is a fraction that is represented with its quotient and remainder. For example there is a mixed fraction [tex]5\frac{2}{3}[/tex] where 5 is the quotient and 2 is the remainder. To convert a mixed fraction to a simple fraction we multiply the denominator by the quotient and add the remainder to it to get the numerator of the simple fraction, the denominator remains the same. In this question we have to find the cups of ingredients that Natasha uses to make the sauce, we have to simplify all the mixed fractions and then add the fraction together to get the number of cups.

cups of cream=[tex]2\frac{3}{4}[/tex]=11/4

teaspoon of salt =1/2

cups of chive=3/8

cups pf butter=[tex]1\frac{1}{4}[/tex]=5/4

total cups of ingredients used= 11/4+3/8+5/4=(22+3+10)/8=35/8≈4 cups

Therefore we found out that the total number of cups natasha uses to make the sauce is 4.

Area of rectangle = length × breadth

length of the rectangle = 4 foot  

breadth = 8 foot.

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.

Since we have to cut the plywood.

And, form a square from it.

we know that all sides of square are same.

The largest square you can cut from a rectangle will have a side length equal to the smallest dimension of the rectangle.

The total mass of the paper clips in scientific notation is 2.226*10 mg

We know that the mass of a single paper clip is:

M = 7.0*10⁻⁴ mg

And in one box has a total of 3.18*10⁴ clips inside of it, then the total mass of the paper clips on the box will be equal to the product between the mass of a single clip and the total number of clips.

We will get:

total mass = (7.0*10⁻⁴ mg)*(3.18*10⁴)

Using the associative property we can rewrite:

total mass = (7.0*3.18)*(10⁻⁴*10⁴) mg

                 = (22.26)*(10⁰) mg = 22.26 mg

Now we want to write this in scientific notation, so we need to have a single digit in the left of the decimal point, then we can rewrite this as:

22.26 mg = 2.226*10 mg

The measure of the angle labelled y as represented in the image attached to the task content is; 125°.

It follows from the task content that the value of angle y is to be determined from the image attached to the task content.

On this note, one must recall that from polygon theorems; the sum of all exteriors angles of a polygon is equal to; 360°.

Therefore; we have;

60° + 70° + 65° + 40° + y° = 360°

By isolating y°; we have;

y° = 360° - 60° - 70° - 65° - 40°

y° = 125°

Answer:

x² + (y – 3)² = 36  

and

x²+ (y + 8)²= 36  

Step-by-step explanation:

The equation of circle that has a center (a, b) is given by the formula

(x - a)² + (x - b)² = r²

where r is the radius of the circle

If the circle lies on the y axis, its x-coordinate must be 0.
The radius of the circle = 1/2 x diameter = 1/2 x 12 = 6 units

So the equation must be of the form
(x - 0)² + (y - b)² = 36

We can eliminate x² + (y – 5)² = 6
We can also eliminate (x + 6)² + y² = 144

That leaves us with the two possible equations

x² + (y – 3)² = 36   (center at 0, 3)

and

x²+ (y + 8)²= 36   (center at (0, -8) )

The variables are:

a) discrete.

b) continuous.

c) continuous.

d)  discrete.

e) continuous.

f)  discrete.

A continuos variable can take any value in a dense set, while a discrete variable can only take some selected values.

a) "Bag of apples"

Here the variable is the number of apples in the bag, we can only have whole numbers of apples, then this variable is discrete.

b) "Distance from here to the moon"

This is a distance, so the value is continuous.

c) "Area of a circle"

Exactly like in the case above, the area is continuous.

d) "Number of telephone calls made each day"

Like in the first example, here the variable can only take whole numbers thus, it is discrete.

e) "The height of a ball as it is thrown into the air."

Similar than case b, a height can take any value on a given range, thus, this is continuous.

f) "The balance in an account over a week."

Here the balance can only be a number followed by 2 digits after the decimal point, so from:

$23.50

We can only go up to:

$23.51

Total                          50                       250                        2500

Total                          50               150

The median class is 40 -60 as cf ≥ N/2

which is 33 ≥ 25

medain = 40 + |25-15|/18 ×20

medain = 40 + 200/18

median = 41.111

Mode = lower limit + f1-f0/2f1-f0-f2 × height

Here, f1 is the frequency of the modal class = 18.

f0 is the frequency of the preceding modal class = 9.

f2 is t/he frequency of the succeeding modal class = 13.

Mode = 40+ 18-9/2(18)-9-13

Mode = 52.857

Hence, the modal price is 52.857.
