If people blink about 13 times per minute, how many times do they blink in 7 hours?

Answer:

C

Step-by-step explanation:

The area of the composite figure to the nearest whole number is 13 ft².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

Given:

Radius= 2 feet

As, Area of a single Quadrant = πr²/4

and, For 3 semi circle

= πr²/4 + πr²/4 + πr²/4 or 3 (πr²/4)

= 3 x 3.14 x 2 x 2 /4

= 9.42 ft²

and, Area of Square

= s x s

= 2 x 2

= 4 ft²

So, the Area of Figure = 4 + 9.42 = 13.42 ft²

Answer: 2/3x-13/12=-5/12x

Step-by-step explanation:

The equivalent equation is (8x + 5x)/12 = (3 + 10)/12 and x = 1.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an equation.

We have,

(2/3)x - 5/6 = -(5/12)x + 1/4

Add like terms.

(2/3)x + (5/12)x = 1/4 + 5/6

(8x + 5x)/12 = (3 + 10)/12

13x / 12 = 13/12

x = 1

Thus,

x = 1

Answer:

Low cost will result in more supply and low customer demands as demands decrease this will result in increase of supply,so low unit cost will is better value only if you purchased all the items to get lower unit rate.

Unit rates are the rates of one quantity.

Paul's claim about unit rates is correct.

From the question, we understand that Paul's claim that lower unit rates are better.

Take for instance, the following unit rates of a computer device in two stores are:

[tex]Rate\ 1 = \$50/computer[/tex]

[tex]Rate\ 2 = \$55/computer[/tex]

The sales of two computers in both stores would cost

[tex]Store\ 1 = \$100[/tex]

[tex]Store\ 2 = \$110[/tex]

By comparison, the cost of 2 computer devices in store 1 costs lesser because store 1 uses a lesser unit rates.

Hence, Paul's claim about unit rates is correct.

Step-by-step explanation:

Area of the shaded region =[ (3x-2)(x+3) ] - [ x*6 ]

= 3x*x +3x*3 + (-2)*x  + (-2)*3 - 6x

=3x² + 9x - 2x - 6 - 6x      {bring like term together}

=3x² + 9x - 2x - 6x - 6

= 3x² + x - 6           {9x - 2x - 6x = 9x - 8x = x}

Area = 24 square units

3x² + x - 6 = 24

3x² + x - 6 - 24 = 0

3x² + x - 30 = 0

Product = 3* -30 = -90

Sum = 1

Factors = 10 , (-1)

3x² + x - 30 = 0

3x² - 9x + 10x - 10*3 = 0

3x*(x - 3) +10*(x - 3) = 0

(x-3)(3x +10) = 0

3x + 10 is ignored because measurements will not be in negative values.

The solution to the equation 3a-7(3-a)=5 is a=13/5.

Let's solve for a in the equation:

3a-7(3-a)=5

We can solve the equation by rearranging the terms, distributing, combining like terms, adding/subtracting to both sides, dividing both sides by the same factor, and simplifying.

Steps to solve:

Rearrange terms:

3a-7(-a+3)=5

Distribute:

3a+7a-21=5

Combine like terms:

10a-21=5

Add/subtract to both sides:

10a-21+21=5+21

Simplify:

10a=26

Divide both sides by the same factor:

10a/10=26/10

Simplify:

a=13/5

Step-by-step explanation:

The mean is basically the average. To find it, we add up all the numbers and then divide that sum by the number of numbers.

Here, we need to find the sum: 7 + 8 + 9 + ... + 22 + 23. To do so, we can use the formula: [tex]\frac{(a_1+a_n)n}{2}[/tex] , where a_1 is the first number (7 in this case), a_n is the last number (23 in this case), and n is the number of numbers (23 - 7 + 1 = 17 numbers in this case). So: [tex]\frac{(7+23)*17}{2} =255[/tex] is the sum.

Now, we need to divide 255 by the number of numbers, which is 17: 255/17 = 15.

Thus, the mean is 15.

Answer:

183.17 cm cubed

Step-by-step explanation:

You would multiply 1/3 times pi times the radius squared times the height

so it would look like 1/3 * 3.14 * 5 squared * 7

5 squared is 25 and 25 times 7 is 175

Then you multiply 175 by 3.14 giving you 549.5

then you divide 549.5 by 3 resulting in 183.1667

then you round to 183.17 cm cubed

Let x represent number of hours after noon.

We have been given that Sara starts at noon and walks at a speed of 4 miles per hour. So distance covered by Sara in x hours would be [tex]4x[/tex].

We are also told that Eddie leaves the  same place an hour later. This means that Sara will be 4 miles ahead of Eddie as Sara will travel 4 miles in 1 hour.

As Eddie walks in the same direction at a speed of 5  miles per hour. So distance covered by Eddie in x hours would be [tex]5x[/tex].

Total distance covered by Sara when Eddie will start would be [tex]4x+4[/tex].

Now we will equate distance covered by both in x hours as:

[tex]5x=4x+4[/tex]

Let us solve for x.

[tex]5x-4x=4x-4x+4[/tex]

[tex]x=4[/tex]

Since x represents number of hours after noon, so 4 represents 4 hours after noon.

Therefore, Eddie will catch up with Sara at 4:00 pm and option D is the correct choice.

Final answer:

The area of a larger square with side lengths twice that of a smaller square is four times greater. This is because the scale factor for areas is the square of the scale factor for lengths, leading to an area of 64 square inches for the larger square, compared to 16 square inches for the smaller one.

Explanation:

When Marta has a square with a side length of 4 inches and then creates a similar square with dimensions that are twice the first square, we are working with a scale factor in geometry. As the new square has side lengths that are twice that of the original square (4 inches x 2 = 8 inches), the area of the larger square will be greater than that of the smaller square. To find the area of the larger square, we square the side length (8 inches x 8 inches), which gives us 64 square inches. This is exactly four times the area of the first square (4 inches x 4 inches = 16 square inches), since the scale factor for the areas of similar figures is the square of the scale factor for their corresponding lengths.

In the context of the examples given, this principle applies to understanding how the area of shapes scales when their dimensions are proportionally increased or decreased. The scale factor can be used to calculate dimensions or area of similar figures in various geometric problems.
