Are the two triangles below similar?

Answer:

Henry = 12 hours        

Robert = 10 hours

that 2 people

so 12/ divided by how many people

and 10/ divided by how many people

so 12/2

and 10/2

= 5 and 6

then find the (median) middle of both numbers one or more  

which is 5 1/2

so they can finish working together in 5 1/2 hours

We conclude that the parent function f(x) = √x has been shifted 1 unit to the left and 5 units downwards.

For a function f(x), a vertical translation of N units is written as:

g(x) = f(x) + N

For a function f(x), a horizontal translation of N units is written as:

g(x) = f(x) + N

Here we have f(x) = √x, and g(x) = √(x + 1) - 5

Then:

g(x) = f(x + 1) - 5

From this, we conclude that the parent function f(x) = √x has been shifted 1 unit to the left and 5 units downwards.

Step-by-step explanation:

The average rainfall in December is 4.15 inches. Therefore option C is the answer.

Given that,  in Pensacola, Florida, the average rainfall in the month of July is 7.40 inches. By  October, the average rainfall decreases by  35%. By December, the average rainfall drops another 0.66 inches.

We need to find the average rainfall, in inches, in  December.

The term "average annual rainfall" refers to the sum of the yearly precipitation totals for a location during a year as determined by the nearest National Weather Service station over the three decades prior.

In July, rainfall was 7.40 inches. By  October, the average rainfall decreases by  35%.

That is, 7.40-35% of 7.40

=7.40-0.35 × 7.40

=7.40-2.59=4.81

By December, the average rainfall drops another 0.66 inches.

That is, 4.81-0.66=4.15

The average rainfall in December is 4.15 inches. Therefore option C is the answer.

Answer:

240 cartons

Step-by-step explanation:

First, I need to find the volume of the 2 objects.

If the measurements of the carton is 1 x 1 x 1, ultimately the volume of the carton is 1 cubic foot.

Then, to find the shipping crate volume, multiply 5 x 12 x 4. You will get 240 cubic feet.

Then, we need to find how many cartons can fit in the shipping crate. Divide 240 by 1, and obviously you get 240.

So, 240 cartons can be packed into the shipping crate.

Answer:

divide both sides of the inequality by -2 and flip the inequality sign the you get (x < 3)

To solve the inequality -2x > -6, divide both sides by -2, remembering to reverse the inequality sign, to obtain x < 3 as the solution.

To solve the inequality -2x > -6, we start by isolating the variable x. To do this, we divide both sides of the inequality by -2. It's important to remember that when we divide or multiply both sides of an inequality by a negative number, we must reverse the direction of the inequality sign. Thus, dividing by -2, the inequality becomes x < 6/2. Simplifying further, we find that x < 3.

Others parts of the referenced information discuss concepts like absolute values, z-scores, and transitivity of numbers but are not directly relevant to solving this inequality.

Hence, the correct answer to the inequality is x < 3.

Answer:

-8

Step-by-step explanation:

Final answer:

Upon checking both inequalities, the point (1, 7) satisfies y < x + 8 and y ≤ 6x + 1. Thus, (1, 7) is a solution to the system of inequalities.

Explanation:

To determine if the point (1, 7) is a solution to the given system of inequalities, we need to check if the point satisfies both inequalities. The system is:

y < x + 8

y ≤ 6x + 1

For the first inequality:

y < x + 8

7 < 1 + 8

7 < 9 ⇒ True

For the second inequality:

y ≤ 6x + 1

7 ≤ 6(1) + 1

7 ≤ 7 ⇒ True

Since the point (1, 7) satisfies both inequalities, it is indeed a solution to the system.

Answer:

Kayla plays on average 0.2 more chess games than Becker

Step-by-step explanation:

The first thing we must do is calculate the mean of each one.

Becker:

(5 + 2 + 4 + 1 + 1 + 4 + 5 + 3 + 2 + 1) / 10 = 2.8

Kayla:

(2 + 3 + 1 + 1 + 4 + 1 + 5 + 3 + 5 + 5) / 10 = 3

if we subtract these averages, we have to:

3 - 2.8 = 0.2

which means that Kayla plays on average 0.2 more chess games than Becker. Since it is not even a complete game, the difference between the two is very small and almost irrelevant.

g= L/(T/2π)²

Step-by-step explanation:

To solve for L in the equation T=2π√L/g, we square both sides to get T² = 4π²L/g. Then, multiplying both sides by g gives gT² = 4π²L. Finally, dividing by 4π² gives the rearranged formula L = gT²/(4π²).

The initial formula T=2π√L/g denotes the period of one swing of a simple pendulum, where T is the period, L is the length of the string, and g is the acceleration due to gravity. To solve for L, we first need to square both sides of the equation to get rid of the square root, resulting in T² = 4π²L/g. Then we multiply both sides by g to get gT² = 4π²L. Finally, we divide both sides by 4π² to solve for L: L = gT²/(4π²). This is the rearranged formula to solve for the length of the pendulum in terms of π, T, and g.

Answer:

X=90 degrees, Y=134 degrees, Z=136 degrees

Step-by-step explanation:

X=90 degrees. It is supplementary to the right angle or forms 180 degrees with it.

The triangle angles add up to 180 degrees.  Therefore, the angle supplementary to Y is 180-(90+44)=46.  Now, 180-46=134.  You could also use the exterior angle theorem which states that the exterior angle is equal to the sum of the two remote interior angles.  The 2 remote interior angle to y would be 90 and 44.  90+44=134=y.

Z is  supplementary to 44 because it is also 180 degrees.  Z=180-44=136 degrees.

Answer:

x = 90

y = 134

z = 136

Step-by-step explanation:

The right angle measures 90 degrees.

x + 90 = 180

x = 90

z + 44 = 180

z = 136

Theorem:

The measure of an exterior angles of a triangle equals the sum of the measure of the two remote interior angles.

Using the theorem, we get

y = 90 + 44

y = 134

Answer:

x = 90

The inequality fir the given phrase is x+14≥18, the solution for the obtained inequality is x≥4.

The given phrase is "The sum of a number and 14 is at least 18".

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Let the unknown number be x.

Here, the inequality is x+14≥18

Subtract 14 on both the sides of an inequality, we get

x+14-14≥18-14

x≥4

Therefore, the inequality fir the given phrase is x+14≥18, the solution for the obtained inequality is x≥4.

Final answer:

The sum of a number and 14 is at least 18' can be expressed as the inequality x + 14 >= 18, indicating that the unknown number must be 4 or greater.

Explanation:

The student's question involves setting up an inequality to represent the situation described.

The problem statement, 'The sum of a number and 14 is at least 18,' translates to a mathematical inequality as follows:

Let 'x' represent the unknown number.

The problem states that when you add 14 to this number, the result should be at least 18. Therefore, the inequality would be:

x + 14 >= 18.

To solve this inequality, you would subtract 14 from both sides:

x = 18 - 14

x = 4

This means the unknown number must be 4 or any larger number. In other words, any number greater than or equal to 4, when added to 14, will be at least 18.

The mean of the number of real messages you should expect to find in your inbox is 22.75

Step-by-step explanation:

According to the given data we have the following:

reported spam email messages percenatge=91%

number of messages in inbox=25

Therefore, In order to calculate the mean of the number of real messages you should expect to find in your inbox we would have to use the following formula:

Mean ( np ) =number of messages in inbox*reported spam email messages percenatge10 * 0.6 = 6

Mean ( np ) =25 *0.91= 22.75

The mean of the number of real messages you should expect to find in your inbox is 22.75

To find the mean of real messages in an inbox, subtract the percentage of spam messages from 100% to obtain the real message percentage. The mean number of real messages is then calculated by finding 9% of the total number in the inbox. For an inbox with 25 messages, the mean number of real messages would be 2.25.

To find the mean number of real messages we would expect in an inbox containing 25 emails, we need to utilize percentages first. According to the data given by Postini, 91% of email messages are spam, which implies that the rest, 9% (100% - 91%), are real messages.

To find the expected number of real messages, we calculate 9% of the total number of messages, in this case, 25. This calculation leads us to:

0.09 * 25 = 2.25

Therefore, the mean number of real messages we can expect to find in an inbox of 25 messages is 2.25.

Answer:

Step-by-step explanation:

Given the function:

[tex]m(x)=-(x-5)^{2} +25[/tex]

As we know the above function is a quadratic equation (vertical parabola) open downward and the vertex is the maximum number of mosquitoes.

The vertex form of a quadratic function is:

[tex]y=a(x-h)^{2} +k[/tex] where (h,k) is the vertex

Our given function have the vertex form as well, so the

(h,k) = (5,25)

At the height of 5 cm the rainfall will produce the maximum number of mosquitoes

Final answer:

In the function modeling the number of mosquitoes by rainfall, 5 centimeters of rainfall will produce the maximum number of mosquitoes, corresponding to the vertex of the parabola.

Explanation:

To find the number of centimeters of rainfall that will produce the maximum number of mosquitoes in Minneapolis, Minnesota, we look at the vertex of the parabolic function m(x) = -(x - 5)2 + 25. The vertex form of a parabola is given by f(x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. In this equation, h represents the x-value that results in the maximum y-value for the parabola when a is negative, which corresponds to the maximum number of mosquitoes.

In this case, the vertex of the parabola is (5, 25), which tells us that 5 centimeters of rainfall will produce the maximum number, which is 25 million mosquitoes. This value is represented by h in the vertex form of the equation, indicating that the parabola opens downwards (since the coefficient of the (x - h)2 term is negative) and reaches its maximum at x = 5.
