help me figure this out answer with a good sketch and anwser.

square: 13² = 169 square units

rectangle: 15 x 8 = 120 square units

this will provide you the answer

44 practice, 113 machine, and 93 game balls

===========================================================

Explanation:

He bought 20 fewer game balls than pitching machine baseballs, which means,

z = y-20

Since the coach bought 250 baseballs total we can also write

x+y+z = 250

Let's replace z with y-20 and simplify

x+y+z = 250

x+y+y-20 = 250

x+2y = 250+20

x+2y = 270

Now let's calculate the subtotal costs for each type of baseball

Those subtotals add to this

1.75x+2.80y+6.25z = total cost = $974.65

1.75x+2.80y+6.25z = 974.65

Like before, I'll replace z with y-20

1.75x+2.80y+6.25(y-20) = 974.65

1.75x+2.80y+6.25y-125 = 974.65

1.75x+9.05y = 974.65+125

1.75x+9.05y = 1099.65

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

So far we have this system of equations

[tex]\begin{cases}x+2y = 270\\1.75x+9.05y = 1099.65\end{cases}[/tex]

I'll use substitution to solve the system.

Isolate x in equation (1)

x+2y = 270

x = 270-2y

Then plug this into equation (2) and solve for y.

1.75x+9.05y = 1099.65

1.75(270-2y)+9.05y = 1099.65

472.5-3.5y+9.05y = 1099.65

472.5+5.55y = 1099.65

5.55y = 1099.65-472.5

5.55y = 627.15

y = 627.15/5.55

y = 113

There are 113 pitching machine baseballs.

Use this y value to find x

x = 270-2y

x = 270-2(113)

x = 270-226

x = 44

There are 44 practice baseballs.

Also, we can say,

z = y-20

z = 113-20

z = 93

There are 93 game balls.

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

Check:

x+y+z = 44+113+93 = 250 baseballs total

A+B+C = 77+316.40+581.25 = 974.65 = total cost

Everything checks out. Also note that value of z is 20 fewer than the value of y.

Answer:

113`F= 46.11° Celsius

Step-by-step explanation:

(Celsius°C × 9/5) + 32 = Fahrenheit

(Celsius°C × 9/5) + 32 = 113

(Celsius°C × 9/5) = 113 - 32

(Celsius°C × 9/5) = 83

Celsius = 5(83)/9

Celsius  = 46.11° Celsius

Answer:

The number is 5

Step-by-step explanation:

Let the number be x,

13 - x = 2x - 2

or, 13 + 2 = 2x + x

so, x = 5

A regression can be modeled by linear regression, quadratic regression, quartic regression or exponential regression

The quadratic regression equation that models the data is

[tex]\^y = -0.875\^x^2 -3.596\^x +20.179[/tex]

The table entries are given as:

x: 0,1,2,3,4,5

y: 20,16,10,0,-7,-20

A quadratic regression is represented as:

[tex]\^y = a\^x^2 + b\^x + c[/tex]

Using a graphing calculator to determine the quadratic regression equation, we have the following calculation summary

a = -0.875

b = -3.596

c = 20.179

Hence, the quadratic regression equation is:

[tex]\^y = -0.875\^x^2 -3.596\^x +20.179[/tex]

Additional comment

When it comes to exponents, I find it useful to remember that an exponent signifies repeated multiplication: x·x·x = x³. The exponent outside parentheses has the same meaning:

  (x³)² = (x·x·x)·(x·x·x) = x⁶

The rule is summarized by ...

Seafloor spreading can be defined as a process that involves the formation of new oceanic crust as a result of volcanic activities and an upwelling of molten magma at mid-ocean ridges, as well as a slowly increasing distance (outward movement) from the ridge.

The theory of seafloor spreading was established by Harry Hammond Hess and it can be used to explain in details the slowly increasing distance between South America and Africa which grows from the center.

A hot spot refers to an area deep within Earth's mantle or under the rocky outermost layer of Earth, from which heat rises through convection and acquired as heat energy by a landform.

In the United States of America, you will see a layered sedimentary rock that is exposed by erosion when you view the Grand Canyon.

Furthermore, Australia is made up of relatively old and thick continental crust. Also, subduction causes the formation of extremely deep ocean Marianas Trench.

The correct answer is z can take on the values of both -6 and 6, not -5 and 5.

The equation that has both -5 and 5 as possible values of z is:

[tex]z^2 = 36[/tex]

When we solve this equation, taking the square root of both sides, we get:

z = ±6

Therefore, z can take on the values of both -6 and 6, not -5 and 5.

Hence, none of the given equations have both -5 and 5 as possible values of z.For the equation z^2 = 36, we need to find the values of z that satisfy the equation. Taking the square root of both sides, we get:

z = ±√36

Simplifying the square root of 36, we have:

z = ±6

This means that z can take on the values of both -6 and 6. However, the values -5 and 5 are not solutions to this equation.

Similarly, for the equation z^3 = 125, there are no values of z that satisfy the equation for z equal to -5 or 5.

Therefore, none of the given equations, z^2 = 36 and z^3 = 125, have both -5 and 5 as possible values of z.

Percentage is represented by '%' symbol. The final cost of the bike will be equal to $490.

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

Given to us

The initial cost of the bike, P = $950

Additional coupon = 30%

Marked down = $200

We know the original cost of the bike which is $950. therefore, when the price of the bike was marked down, its cost will be,

$900 - $200 = $700

Thus, the marked-down cost of the bike will be $700.

As it is given that we have an additional 30% off after the markdown, therefore, cost of the bike will be 70% of the marked price,

[tex]70\%\ of\ \$700\\\\ = 0.70 \times 700\\\\= \$490[/tex]

Hence, the final cost of the bike will be equal to $490.
