Step-by-step explanation:

9z-3w

9(5)-3(5)

Multiply:

45-3(5)

Multiply:

45-15

Subtract:

= 30

The lengths of the three sides are 14 feet, 17 feet, and 25 feet.

Let's assume that the shortest side of the triangular deck has a length of x feet.

According to the given information, the second side of the deck is 3 feet longer than the shortest side. Therefore, its length would be (x + 3) feet.

The third side of the deck is 3 feet shorter than twice the length of the shortest side. Hence, its length would be (2x - 3) feet.

The perimeter of a triangle is the sum of the lengths of its sides. In this case, the perimeter is given as 56 feet. So, we can set up the following equation:

x + (x + 3) + (2x - 3) = 56

Simplifying the equation, we have:

4x = 56

Dividing both sides by 4, we find:

x = 14

Now, we can substitute the value of x back into the expressions for the

second and third sides:

Second side: x + 3 = 14 + 3 = 17 feet

Third side: 2x - 3 = 2(14) - 3 = 25 feet

Marked price = $36

Marked down = 30%

Amount of mark down

Or

Sale price

Answer:

$25.2

Step-by-step explanation:

We know that the original price is $36 and it was marked down 30%.

Turn the percentage into a decimal.

30% = 0.3

Multiply.

36 * 0.3 = 10.8

Subtract.

36 - 10.8 = 25.2

Answer:

50, 130

Step-by-step explanation:

Since they are a linear pair they add to 180

z + ( 2.4z+10) = 180

Combine like terms

3.4z + 10 = 180

Subtract 10 from each side

3.4z+10-10 = 180-10

3.4z = 170

Divide each side by 3.4

3.4z/3.4 = 170/3.4

z = 50

2.4z + 10 = 130

Step-by-step explanation:

This is simply what the chart shows, as well as I got this correct on Edge :)

Answer:

B.

Step-by-step explanation:

Let's write an equation that expresses the relationship.

Let s denote the amount of spiders.

We know that every time Alex catches one spider, the remaining population doubles.

So, if s represent the population of spiders, if Alex catches 1, then the population will become (s-1).

However, for every catch, the population doubles, so, the new population will be 2(s-1).

Therefore, we can write the following equation:

[tex]s_n=2(s_o-1)[/tex]

Where s_n represents the new population and s_o represents the original population.

We know that there are now 194 spiders in Alex's house. We want to find the number of spiders in his house before he caught the last 2 spiders. So, let's solve for s_o twice.

Substitute 194 for s_n. Solve for s_o:

[tex]194=2(s_o-1)[/tex]

Divide by 2:

[tex]97=s_o-1\\\Rightarrow s_o=98[/tex]

Therefore, before catching the last spider, there were 98 spiders.

So, to find the number of spiders before the last 2, we will solve for s_0 again. This time, we will use 98 for s_n. So:

[tex]98=2(s_0-1)[/tex]

Solve for s_o:

[tex]\Rightarrow 49=s_o-1\\\Rightarrow s_o=50[/tex]

Therefore, there were 50 spiders in Alex's house before he caught the last 2 spiders given that the current population is 194 spiders.

Our answer is B.

Answer:

Step-by-step explanation:

The Sequence is not properly written. Here is the correct sequence

408, 433, 458...

THe sequence is an arithmetic sequence. The nth term of an arithmetic sequence is expressed as;

[tex]T_n = a+(n-1)d[/tex] where;

a is the first term

d is the common difference.

Common difference is the constant value that is being added to preceding term of the sequence to get the next value in the sequence.

T1 = 408

T2 = 433

T3 = 458

d = T3-T2 = T2-T1

d = 458-433 = 433-408

d = 25

Hence the common difference in the sequence is 25

Answer:

The spindle speed is 37.4 rev./ min

Step-by-step explanation:

This is a form of joint variation. From the question, it can be deduced that:

S [tex]\alpha[/tex] [tex]\frac{C}{D}[/tex]

S = [tex]\frac{KC}{D}[/tex]

where K is the constant of proportionality.

Given that:

C = 50 feet per minute, D = 2 inches, S = 93.5 rev/ min, thus;

K = [tex]\frac{SD}{C}[/tex]

  = [tex]\frac{2*93.5}{50}[/tex]

  = [tex]\frac{187}{50}[/tex]

  = 3.74

K = 3.74

When D = 4 inches, C = 40 feet /minute, the S can be determined by;

S = [tex]\frac{KC}{D}[/tex]

  = [tex]\frac{3.74*40}{4}[/tex]

  = 37.4 rev./ min

Given the set B = {4, 9}, the inverse image  f⁻¹(B) is a collection of all real numbers whose squares are either 4 or 9. This set can be expressed as f⁻¹(B) = {-2, 2, -3, 3}.

Let's use mathematical language to represent the direct image as f(A), where a mapping function  takes a set A as input and generates its corresponding image.

The set of inputs that correspond to a certain set B is referred to as the inverse image or f⁻¹(B).

To illustrate this concept effectively, let's analyze a practical scenario. Suppose there exists a mathematical function denoted as  that maps real numbers to their respective squares by using the equation f(x) = x².

Given the set B = {4, 9}, the inverse image  f⁻¹(B) is a collection of all real numbers whose squares are either 4 or 9. This set can be expressed as  f⁻¹(B) = {-2, 2, -3, 3}. The elements in set B are the result of squaring the inputs corresponding to these values.

The distance the Morris family travels depends on the number of hours they travel, and can be calculated as 45 times the number of hours they travel.

The distance travelled as a function of the number of hours at an average speed can be expressed using the formula:

distance = speed x time, or d = st

In this case, the Morris family is traveling from Providence to Fredricksburg at an average speed of 45 miles per hour. Let t represent the number of hours they travel.

Therefore, the distance they travel can be expressed as:

distance = speed x time = 45t miles.

For example, if the Morris family travels for 4 hours, then the distance they travel is:

distance = 45 x 4 = 180 miles.

If they travel for 6 hours, then the distance they travel is:

distance = 45 x 6 = 270 miles.

Step-by-step explanation:

The dimensions of the smaller rectangle are 13 centimeters by 52 centimeters.

Let's assume the dimensions of the smaller rectangle are length L and width W (in centimeters).

We know that the area of the smaller rectangle is 676 square centimeters:

L * W = 676    ----(1)

We also know that the larger rectangle has a shorter side of 41 centimeters. Let's say the corresponding longer side of the larger rectangle is H centimeters.

The area of the larger rectangle is 3457 square centimeters:

41 * H = 3457    ----(2)

Our current set of equations contains two unknowns. In order to get the smaller rectangle's dimensions, we can simultaneously solve these equations.

In order to find H, we can use equation (2):

H = 3457 / 41

H ≈ 84.22

Now we can substitute this value of H into equation (1):

L * W = 676

We need to find the dimensions (L and W) that multiply to give 676. We can start by looking for factors of 676.

Factors of 676: 1, 2, 4, 13, 26, 52, 169, 338, 676

By trial and error, we can see that the factors that give a close match to the dimensions of the larger rectangle (41 and 84.22) are 13 and 52:

L = 13

W = 52

Therefore, the smaller rectangle has measurements of 13 by 52 centimetres.
