Brian tied a 136-foot rope around the perimeter of his rectangular house. He knows that the length of the house is 10 feet less than twice the width. Find the dimensions of Brian’s house.

Answers

Answer:

length 42 cm and width 26 cm

Step-by-step explanation:

Given

Since Brian tied 136 foot rope around the perimeter , hence perimeter of house is 136 foot.

Given that shape of house is rectangular.

formula to calculate perimeter of rectangle can be used which is 2*(L+B)

where L is length of rectangle and B width of rectangle

Let the L and B be length of rectangular side of house

According to question

length of house is 10 feet less than twice the width of house

mathematically it can be represented as

L = 2*B - 10  --->eq. 1

Perimeter of house = 136 feet

using formula of Perimeter of rectangle

136 = 2*(L+B)

substituting the value of length in terms of width from eq. 1 in formula of perimeter

=> 136/2 = 2*B - 10 + B  (2*B+ B = 3B)

=> 68 = 3*B - 10

=> 78 = 3*B

B = 78/3 = 26

Therefore B which is width = 26 CM

length = 2*B - 10= 26*2 - 10 = 52-10=42

length of house = 42  cm

Hence dimension of Brian's house is length 42 cm and width 26 cm

-20-7x=-2x+2 solve the equation

Answers

Answer:

-4.4

Step-by-step explanation:

In order to do this, we need to move the variables to one side, and the numerical values to the other.

-20-7x=-2x+2

We can do this by adding 7x to both sides first

-20=5x+2

Now we can subtract 2 from both sides.

-22=5x

Next, we can divide each side by 5.

x=-22/5

Then we simplify the fraction

x=-4.4

Answer:

x = -4.4

or

x = 22/-5

Step-by-step explanation:

-20-7x = -2x+2

-7x = -2x+20+2

2x-7x = 22

-5x = 22

x/-5 = 22/-5

x = -4.4

or

x = 22/-5

The Smiths spend 6% of their budget on entertainment. Their total budget this year is $3,000 more than last year, and this year they plan to spend $2,580 on entertainment. What was their total budget last year?

Answers

Answer: Their total budget last year was $40,000.

Step-by-step explanation:

Given : The Smiths spend 6% of their budget on entertainment.

i.e. , The money they spend on entertainment = 0.06 x ( Total budget)

{ 6% is converted to 0.06 , when we divide it by 100 to remove percentage)

Since , this year they plan to spend $2,580 on entertainment.

i.e. 0.06 x ( Total budget )  = $2,580

On dividing both sides by 0.06 , we get

( Total budget )  = $2,580 ÷ 0.06

=  $43,000

Thus , their total budget for this year = $43,000

Also, Their total budget this year is $3,000 more than last year.

Therefore , their last year total budget = ( Total budget this year ) - $3000

= $43,000 - $3000

= $40,000

Hence, their total budget last year was $40,000.

The next day is sunny.

What can you conclude? What law did you use to draw this conclusion?

Answers

Answer:

I can conclude that Sally went down the slide. I used deductive reasoning to get my answer. Sally said that if it was sunny, she would go to the park. She also said that if she does go to the park, she will go down the slide. Since Sally did go to the park, I know that she did go down the slide. Based on the information I have, I can use deductive reasoning to get to my answer.

Step-by-step explanation:

Final answer:

Based on Sally's conditions and the law of syllogism, since it's sunny, we can conclude Sally will go to the park and go down the slide.

Explanation:

From Sally's statements, since the next day is sunny, we can conclude that Sally will go to the park and go down the slide. This conclusion is based on the law of syllogism in logic, which allows us to link two related conditional statements. In this scenario, the first conditional statement is 'If it's sunny, I will go to the park', and the second is 'When I go to the park, I go down the slide'. As it's sunny, the law of syllogism lets us link these conditions to infer that Sally will indeed go down the slide at the park.

Restaurants often slip takeout menus under Maura's apartment door. So far, Maura has collected 15 menus, including 3 for Chinese food. Considering this data, how many of the next 20 menus slipped under Maura's door should you expect to be from Chinese restaurants? menus

Answers

Based on the proportion of Chinese food menus Maura has already received (3 out of 15),we would expect her to receive approximately 4 Chinese food menus in the next batch of 20 menus.

To solve this, we look at the probability of Maura receiving a Chinese food menu by using the proportion of Chinese menus she has already received.

This initial probability is 3 out of 15, which simplifies to 1 out of 5. Therefore, we'd expect to receive the same proportion from the next set of menus.

To predict the number of Chinese food menus in the next 20, we multiply the total number of new menus by the probability of each being Chinese:

20 menus * (1/5 probability of Chinese) = 4 Chinese menus

Answers

Answer:

64,125 I think

Step-by-step explanation:

7%x 5 years =35%

35% of 47, 500 is 16625

16625 + 47,500=64,125

Answer:

about $66,621

Step-by-step explanation:

Since its an increase in salary, we want 0.07+1 = 1.07 (if he was losing his salary, it instead would be 0.07-1, but that's not the case here)

Then we plug it in as 47,500(1.07)^x

he's expecting what would he get in his fifth year at the firm. So let's set x = 5.

47,500(1.07)^5 = $66,621.20721 or ≈ $66,621 to the nearest dollar.

Answer:

Area of blank is 326.56m²

Step-by-step explanation:

For a better and pictorial understanding of this problem please see attached for your reference.

Given data

Let the flower bed be the small circle with diameter d= 22m

Radius of small circle = 22/2=11m

Let the side walk be the big circle with diameter D= 4+4+22=30m

Radius of big circle =30/2 = 15m

We know that the area of circle

Write three equations whose solution is x=3.5

Answers

Final answer:

To write three equations whose solution is x=3.5, you can use different algebraic expressions. Three examples are x + 2 = 5.5, (2x - 5) / 3 = 1.8333, and x^2 - 12x + 42 = 0.

Explanation:

To write three equations whose solution is x=3.5, we can use different algebraic expressions to represent the same value. Here are three examples:

x + 2 = 5.5 - In this equation, if we substitute x with 3.5, we get 3.5 + 2 = 5.5, which is true.(2x - 5) / 3 = 1.8333 - If we plug in x=3.5, we get (2(3.5) - 5) / 3 = 1.8333, which is true.x^2 - 12x + 42 = 0 - If we solve this quadratic equation, we find x=3.5 as one of the solutions.

Answers

Answer:

Step-by-step explanation:

Answer:

The value of angle A is 19.415 degrees.

Explanation:

Let's recalculate using the Law of Cosines to find the measure of angle[tex]\(A\)[/tex] in triangle [tex]\(ABC\)[/tex].

Given:

- [tex]\(a = 3.4\)[/tex] cm

- [tex]\(b = 7.9\)[/tex] cm

- [tex]\(c = 5.3\)[/tex] cm

We want to find angle [tex]\(A\)[/tex]. To use the Law of Cosines, we first need to find angle [tex]\(C\)[/tex]. We can use the Law of Cosines again:

[tex]\[ a^2 = b^2 + c^2 - 2bc \cos(A) \][/tex]

[tex]\[ (3.4)^2 = (7.9)^2 + (5.3)^2 - 2(7.9)(5.3) \cos(A) \][/tex]

[tex]\[ 11.56 = 62.41 + 28.09 - 83.54 \cos(A) \][/tex]

[tex]\[ 11.56 = 90.5 - 83.54 \cos(A) \][/tex]

[tex]\[ 83.54 \cos(A) = 90.5 - 11.56 \][/tex]

[tex]\[ 83.54 \cos(A) = 78.94 \][/tex]

[tex]\[ \cos(A) = \frac{78.94}{83.54} \][/tex]

[tex]\[ \cos(A) \approx 0.944 \][/tex]

Now, to find the measure of angle \(A\), we take the inverse cosine (cos⁻¹) of 0.944:

[tex]\[ A \approx \cos^{-1}(0.944) \][/tex]

[tex]\[ A \approx 19.415° \][/tex]

In total, there were 170 + 120 + 55 + 20 = 365 flights.Of those, 167 + 115 + 40 + 8 = 330 on time. The percentage on time is:

[tex]P = \frac{330}{365} \times 100\% = 90\%[/tex]

90% on time, and the rest, that is, 100% - 90% = 10% were delayed, and the marginal distribution is described by these percentages.

A similar problem is given at https://brainly.com/question/24372153

The marginal distribution of train arrival status shows that approximately 90% of the time the train is on-time and 10% of the time it is delayed. This is calculated by taking the frequency of each arrival status and expressing it as a percentage of the total number of days recorded by James.

James has been keeping track of the relationship between weather conditions and whether the downtown train runs on time.

To find the marginal distribution of train arrival status in percentages, we need to see the frequency of on-time and delayed trains irrespective of the weather conditions and then express these frequencies as a percentage of the total number of days recorded.

To calculate the on-time percentage:

Total on-time occurrences: 330Total recordings: 365On-time percentage = (Total on-time occurrences / Total recordings) x 100On-time percentage = (330 / 365) x 100 ≈ 90%

To calculate the delayed percentage:

Total delayed occurrences: 35Delayed percentage = (Total delayed occurrences / Total recordings) x 100Delayed percentage = (35 / 365) x 100 ≈ 10%

Therefore, the marginal distribution of arrival status is approximately 90% on-time and 10% delayed.
