The area, to the nearst square inch, of a circle the same size az the bicycle wheel is  531 inches².

A circle is a bounded figure which points from its center to its circumference is equidistant.

Area of a circle = πr²

Where :

π = pi = 22/7

R = radius

The full rotation of the wheel is equal to the circumference of the wheel.

circumference of the wheel = 2 πr

26π = 2 πr

r = 13 inches

Area = 22/7 x 13³ = 531 inches²

Answer:

Step-by-step explanation:

here is a step-by-step explanation:

Convert half a gallon of milk to liters. There are 3.785 liters in a gallon, so half a gallon is 1.892 liters.

Convert 5 ounces to liters. There are 0.147868 liters in 5 ounces.

Divide the total volume of milk (1.892 liters) by the volume of each bottle (0.147868 liters) to find out how many bottles can be filled completely:

1.892 liters / 0.147868 liters per bottle = 12.8 bottles

Note that the answer is not a whole number, which means there will be some leftover milk after 12 bottles are filled.

To find out how many milliliters are in each bottle, we can convert 5 fluid ounces to milliliters:

5 fluid ounces x 29.5735 milliliters per fluid ounce = 147.868 milliliters

Therefore, each bottle will contain approximately 147.868 milliliters of milk.

So, in summary, with half a gallon of milk, you can fill 12 bottles completely and each bottle will contain about 147.868 milliliters of milk.

The area of the triangle is 47.91 units²

When all three sides of the triangle are known we can use Heron's formula. Consider the triangle ABC with sides a, b, and c has shown in the image.

Heron’s formula is:

Area =√s(s−a)(s−b)(s−c)

where,

a, b, c are the side length of the triangle

s is the semi-perimeter. s = (a+b+c)/2

In this case:

Using the knowledge of the radius of a circle. We can say:

a = BC = 3 + 9 = 12 units

b = AC = 5 + 3 = 8 units

c = AB = 5 + 9 = 14 units

s = (a+b+c)/2

s = (12+8+14)/2

s = 34/2

s = 17 units

Area = √s(s−a)(s−b)(s−c)

Area = √17(17−12)(17−8)(17−14)

Area = √17(5)(9)(3)

Area = √2295

Area = 47.91 units²

Given the functions:

We want to find:

First of all, we need to find:

This is done by inserting the value of h(x) into f(x)

So, we have:

Substituting 7 for x in f[h(x)], we have f[h(7)]

Which is what we are looking for.

The inequality c - 7 > 3 is matched to the graph of its solution. The correct answer is option C.

As per the shown number line,

Here, the inequality is inclusive (c ≤ 10), and the point at 10 is included, so use a closed circle to mark the point.

An arrow extends to the left of the marked point. This arrow indicates all the values of c that are less than 10.

If the inequality is strict (c < 10), the arrow should be drawn with an open end.

Thus, the inequality c - 7 > 3 is matched to the graph of its solution.

Hence, the correct answer is option C.

Flagpole                       90                                     x

36/90 = 54 / x                Cross Mulltiply

36x =90 * 54

36x = 4860                    Divide by 36

x = 4860/36

x = 135 inches.

Do you need the height in feet?

That would be 135/12 = 11.25 feet or 11 feet 3 inches.

The possible values for a third quiz score that would give her an average between 85 and 90, inclusive is: 97 ≤ x ≤ 112.

In Mathematics, the average of these quiz scores can be calculated by using the following formula:

Average = Sum of quiz score/Number of quiz scores

Note: Let the variable q represent the student's score on the third (3rd) quiz.

Substituting the given parameters into the formula, we have the following;

Average = (75 + 83 + q)/3

Average = (158 + q)/3

This ultimately implies that, an average between 85 and 90, inclusive is given by this compound inequality:

85 ≤ (158 + q)/3 ≤ 90

Multiplying all through by 3, we have the following:

255 ≤ (158 + q) ≤ 270

Subtracting 158 from both sides of the inequality, we have the following:

97 ≤ x ≤ 112

Answer:

First option is correct.

Step-by-step explanation:

Normally, Pete's dad deposits $25 into his bank account every week.

Now, he wants to deposit x extra dollars for 8 weeks. So, the total deposits for these 8 weeks will be:

8*(25 + x)

He wants to keep the total deposits above 500. So

8*(25 + x) > 500

Now we solve the inequality similarly to how we would solve an equality.

8*(25 + x) > 500

200 + 8x > 500

8x > 500 - 200

8x > 300

x > 300/8

x > $37.50

So the first option is correct.

Answer:

To calculate the fixed expenses each month, we need to add up all the monthly expenses:

Mortgage: $985.64

Cell phone: $58.30

Groceries: $154.00 x 2 = $308.00

Clothing (with 25% job-related): $180.00

Water & electric: $128.40

Weekly dinner & movie: $55.00 x 4 = $220.00

Total monthly fixed expenses: $1,880.34

To calculate how much could be saved per month, we need to first calculate the discretionary income:

Realized income: $2,943.20

Fixed expenses: $1,880.34

Discretionary income: $2,943.20 - $1,880.34 = $1,062.86

25% of discretionary income: 0.25 x $1,062.86 = $265.72

Therefore, the amount that could be saved per month by putting 25% of the discretionary income in a savings account is $265.72.

Answer: Changing the radius of an object by a given amount has a greater effect on the volume than changing the height by the same amount. The volume of a cylinder is given by the formula V = πr²h, where V is the volume, r is the radius, and h is the height. If we change the radius by a given amount, say x, the new radius would be r+x. Hence, the new volume would be V' = π(r+x)²h = π(r²+2rx+x²)h = V + 2πrxh + πx²h. We can see that the volume change equals 2πrxh + πx²h. The first term is proportional to both the radius and the height, whereas the second term is proportional to the square of the radius and the height. Assuming that the height change is also x, the new volume would be V'' = πr²(h+x) = V + πr²x. We can see that the volume change is proportional to the radius squared and the change in height. Therefore, changing the radius by a given amount has a greater effect on the volume than changing the height by the same amount.

Answer:

Step-by-step explanation:

Answer:

∠3 = 108

Step-by-step explanation:

∠1 + ∠2=180 because a straight line is 180°

∠1=5x+10  and  ∠2=9x+2

5x+10  +  9x+2 = 14x+12

14x+12=180

180-12=168

168/14=12

x=12

∠2 = 9x+2 = 110

180-110 = 70

∠4 = 70

∠4 + ∠3 + ∠5 = 180

∠5 = 90 -5x = 30

As a result, the limit value is 0. This indicates that the derivative of the function f(x) = x² when x = -5 equals zero.

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. A function is an equation that depicts the connection between an input x and an output y, with precisely one output for each input. Another name for input is domain, while another one for output is range.

Here,

The limit in question is a definition of the derivative of a function at a point. In this case, we want to evaluate the limit as h approaches 0 of the expression (f(x + h) - f(x)) / h, where f(x) = x² and x = -5.

Substituting the given values, we have:

lim _h right arrow 0 (x² + h²- x²) / h = lim _h right arrow 0 h² / h = lim _h right arrow 0 h = 0

So the value of the limit is 0. This means that the derivative of the function f(x) = x² at the point x = -5 is equal to 0.
