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

Step-by-step explanation:

calculator

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.

Answer:

3/22

Step-by-step explanation:

Reciprocal means the inverse of the fraction. For your mixed number 7 and 1/3, turn it into fraction by multiplying 7 with the denominator which is 3, then add the numerator which is 1 to get the numerator of a normal fraction which is 22. The numerator remains the same.

The fraction is 22/3. As mentioned above, reciprocal means the inverse, so the final answer is 3/22

The reciprocal of a number in mathematics is referred to as the inverse of that number.

This means that:

Given a number x, its reciprocal is :

[tex]x = x/ 1= 1/x[/tex]

Given a number 1/x, its reciprocal is

[tex]1/x = x/1[/tex]

The reciprocal of [tex]7\frac{1}{3}[/tex]  is [tex]\frac{3}{22}[/tex]

From the question, [tex]7\frac{1}{3}[/tex] is called a mixed fraction

Converting to an improper fraction

[tex]7\frac{1}{3}[/tex] = [tex]\frac{22}{3}[/tex]

The inverse of [tex]\frac{22}{3}[/tex]

[tex]\frac{22}{3}[/tex] = [tex]\frac{3}{22}[/tex]

Therefore, the reciprocal of [tex]7\frac{1}{3}[/tex]   is [tex]\frac{3}{22}[/tex]

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:

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:

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.
