Step-by-step explanation:

Givens

Notice that the ramp is formed by two triangles and three rectangles.

Each triangle has a base of 2 feet and a height of 1.5 feet. So, the area of each triangle is

[tex]A_{triangle}=\frac{bh}{2}=\frac{2(1.5)}{2}=1.5ft^{2}[/tex]

The base of the ramp has dimensions of 3 feet x 2 feet. Its are is

[tex]A_{base}=3(2)=6ft^{2}[/tex]

The back of the ram has an area of

[tex]A_{back}=1.5(3)=4.5 ft^{2}[/tex]

The riding surface is

[tex]A_{riding}=3(2.5)= 7.5ft^{2}[/tex]

So, basically, to know the total surface, we just have to sum the are of both triangles, and the area of all three rectangles, as follows

[tex]S=1.5+1.5+6+4.5+7.5=21ft^{2}[/tex]

This means that Trenton needs 21 square feet of plywood to cover all the surface of the ramp.

Answer:

Option B is correct

Step-by-step explanation:

We need to find g(h(f(x))

We first find h(f(x))

f(x) = x-3/x

Putting value of f(x) in place of x in h(x)

h(x) = 2x+1

h(f(x)) = 2(x-3/x) + 1

         = 2(x-3/x) + 1

         = 2x -6 /x +1

         = 2x-6 +x/x

         = 3x-6/x

Now, putting value of h(f(x)) in g(x)

g(x) = x+3

g(h(f(x)))= (3x-6/x) + 3

            = 3x-6/x + 3

            = 3x-6+3x/x

            = 6x-6/x  

So, Option B is correct.

Symbol answer: 6/12 < 9/12

Step-by-Step explanation:

Common knowledge: Anytime you have the same numerator, with a different denominator, the one with the bigger denominator is always smaller. For example, if had a pizza with 6 slices and a pizza with 4 slices, the one with 6 slices and smaller and the one with 4 slices and bigger. Even though 6>4 that mindset has to change when thinking about a problem like this.

Another explanation:

If you still don’t get it, simply find a common denominator, so we’ll choose 12. Take 3/6 and multiply that by 2/2 so you get 6/12 and then take 3/4 and multiply that by 3/3 on both the (numerator and denominator) and that equals 9/12.

So now you have the expression: 6/12<9/12.

Hello there!

Answer:

8/13

Step-by-step explanation:

In order to find the probability in questions like this, we would need to find the number that we want to get and the total amount of possibilities.

Important information in the text:

With the information, we can find the probability.

In the question, we are trying to find the probability of picking out a black sock, and there is 8 black socks. The 8 will go on our numerator.

Our denominator would be the total amount of things that leads to our probability. Since we only have 8 black socks and 5 yellow socks, we would add 8 + 5 to get the total amount of socks.

8 + 5 = 13

The 13 will go in the denominator.

When you put all of the stuff together, you should get 8/13. You can't simplify it because 13 is an odd number that can't get any smaller.

8/13 is the probability of picking out a black sock

Answer:

-4x + y + 6z

Step-by-step explanation:

2x + 5y - z + (-6x - 4y + 7z) < distribute positive 1 to (-6x - 4y + 7z)

2x + 5y - z - 6x - 4y + 7z < combine like terms to get the answer

2x - 6x = -4x

5y - 4y = y

-z + 7z = 6z

our new expression is:

-4x + y + 6z we cannot simplify this any further, so this is our answer

Step-by-step explanation:

step 1

Find the area of the circular region

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=7\ mi[/tex]

assume

[tex]\pi =3.14[/tex]

substitute

[tex]A=(3.14)(7)^{2}[/tex]

[tex]A=153.86\ mi^{2}[/tex]

step 2

Find the number of people who live in the region

Multiply the area by the density

so

[tex]A=153.86*(2,200)=338,492\ people[/tex]

Round to the nearest ten thousand

[tex]338,492=340,000\ people[/tex]

The number of people who live in the region to the nearest ten thousand is 340,000.

Population density is the amount of organisms that live in a square feet of an area.

Population density x area = population

Area = πr²

3.14 x 7² = 153.86 m²

Population = 153.86 x 2200 = 340,000

Answer:

D) The number of bacteria decreases by 7% each hour.

Step-by-step explanation:

Exponential functions describe situations where values do not increase at a linear or constant rate. Adding or subtracting every year or hour will result in a linear function, so A, B, and C are incorrect.

Option (D) The number of bacteria decreases by 7% each hour is correct.

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]

where 'a' is a constant and a>1

As we know, the exponential function increases rapidly according to the exponent.

It is not a linear function, and it never gives a negative value if the value of a>0

As the no other information was given.

Thus, option (D) The number of bacteria decreases by 7% each hour is correct.

Answer:

B

Step-by-step explanation:

B is the correct answer.  Since Mrs. Hooper and Mr. Anderson had to call a total of 8 parents, you know the first equation must be either A or B (H + A = 8).

Since you know that Mrs. Hooper had to call 2 more parents than Mr. Anderson, the equation will have to have H + 2 on one side; that's how you know the correct answer is B.

The set of equations which correctly describes the phone calls made is A. H + A = 8 ; H = A + 2.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

H denote the number of calls Mrs. Hooper made and A denote the number of calls Mr. Anderson made.

Mrs. Hooper and Mr. Anderson had to call a total of eight parents.

So, the equation representing this is, H + A = 8

Mrs. Hooper needed to call two more students than Mr. Anderson.

H = A + 2

So the set of equations are,

H + A = 8 ; H = A + 2

Hence the correct option is A. H + A = 8 ; H = A + 2

Answer:

A. 15

Step-by-step explanation:

To solve this you need to compare the lengths given to you in the question statement.

Because the lines originate from a single point, they're like triangles.  We can easily see a triangle AGF and a triangle ADE, right?

Both triangles are similar triangles, so we can see triangle ADE as a larger version of angle AGF.

They give you the dimension of A F and A E (through A F + F E) to establish a ratio... and they give you A G, asking for A D.

So, A F = 16, A E = 20 (16 + 4), A G = 12.

Since A D is to A G what A E is to A F, we can easily make the following cross-multiplication:

[tex]\frac{A D}{A G} = \frac{A E}{A F}[/tex]

So, A D = (A G * A E)/A F

A D = (12 * 20) / 16 = 15

Multiply the two numbers.

Answer:

D: a single firm supplies all the output.

Step-by-step explanation:

A natural monopoly runs most efficiently when one large firm supplies all of the output.

A natural monopoly occurs when the most efficient number of firms in the industry is one. As the name suggests, monopoly means single. We can also say that it is a market structure characterized by a single seller, selling a unique product in the market.  

A natural monopoly functions by having a single firm supply all output in a specific market, typically due to economies of scale. This usually occurs in markets where having multiple firms would be inefficient and costly, such as utilities. Government usually regulates these to protect consumers.

A natural monopoly functions in a manner where a single firm supplies all the output in a particular market. This is typically because this single firm can produce the total output in the market at a lower cost compared to several firms due to economies of scale. For example, in the utilities industry (like water or electricity), it would be highly inefficient and costly to have multiple firms deliver these services. Therefore, a single firm, or a 'natural monopoly', can provide these services at a lower cost.

The government often regulates natural monopolies to prevent abuse of monopoly power. This is done to ensure fair prices and adequate supply to consumers.

Final answer:

The solution set for the inequality –x ≥ 4 is x ≤ – 4, which includes all numbers less than or equal to – 4. This would be represented on a number line with a solid dot at – 4 and shading to the left.

Explanation:

The question pertains to solving the inequality –x ≥ 4 and representing the solution on a number line. To solve for x, we first multiply both sides by – 1, remembering to reverse the inequality sign since multiplying or dividing by a negative number reverses the inequality:

–x ≥ 4

( – 1)( –x) ≤ ( – 1)(4)

x ≤ – 4

This means that x is less than or equal to – 4. On the number line, the solution set for x includes all numbers to the left of – 4, including – 4 itself. To represent this graphically, one would draw a solid dot at – 4 and shade all the region to the left of – 4, indicating all those numbers are included in the solution set.

Step-by-step explanation:

You have 5 WHITE marbles and 5 Black marbles.

The probability of drawing a WHITE marble is 5/10  or 1/2

And the probability of drawing the second (marble another WHITE marble) is 4/9

So 1/2 x 4/9 = 4/18 or 5/10 x 4/9 = 20/90 / 5 = 4/18

Therefore the probability of drawing a WHITE marble not replacing it then drawing another WHITE marble is 4/18

Answer:   [tex]x=-12.8[/tex]

Step-by-step explanation:

Given the equation [tex]\frac{5x}{8}+10=2[/tex], you need to solve for "x":

Apply the Subtraction property of equality and subtract 10 from both sides of the equation:

 [tex]\frac{5x}{8}+10-10=2-10[/tex]

 [tex]\frac{5x}{8}=-8[/tex]

Apply the Multiplication property of equality and multiply  both sides of the equation by 8:

[tex](\frac{5x}{8})(8)=-8(8)[/tex]

[tex]5x=-64[/tex]

Apply the Division property of equality and divide  both sides of the equation by 5:

[tex]\frac{5x}{5}=\frac{-64}{5}[/tex]

[tex]x=-12.8[/tex]

Final answer:

The expressions 2(x+3) and 2x+4+2x are not equivalent.

Explanation:

To determine if the expressions 2(x+3) and 2x+4+2x are equivalent, we can simplify them and compare the results. Let's simplify each expression when x=1:

2(x+3) = 2(1+3) = 2(4) = 8

2x+4+2x = 2(1)+4+2(1) = 2+4+2 = 8

Both expressions evaluate to 8 when x=1, so they are equivalent. Now, let's evaluate the first expression when x=2:

2(x+3) = 2(2+3) = 2(5) = 10

The first expression evaluates to 10 when x=2, which is different from the value of 8 obtained from the second expression. Therefore, the expressions 2(x+3) and 2x+4+2x are not equivalent.
