As you can see, ABCD is similar to FECG which means its just a bigger or smaller version of the other. The sides change by a specific amount like times 2 or divided by 2

In this case abcd is 2x bigger thab fecg. You can see this by the side BC being 10 and it is the same side on the other shape being 5 so you know FECG is just ABCD x 1/2

Because of this since we know what FG is (4) on FECG we know y is 2x that side so it is 8.

267.4 divided by 1\10

Answers

Answer:

2674

Step-by-step explanation:

267.4 divided by 1/10 is the same as 267.4/.10 which you can use a calculator and solve that easly.

Or you can do 267.4/1 times 10/1 because when you are dividing, you flip the second number and mutply instead of divide. And when doing that, the answer is the same.

A certain store sells only T-shirts. Let the random variable X represent the number of T-shirts bought from the store on any day, with a mean of 75 and a standard deviation of 20. Let the random variable Y be the total revenue from this store on a randomly selected day. If the store charges $15 per T-shirt, what are the mean and standard deviation of Y

Answers

Answer:

[tex](a)\ \mu_y = 1125[/tex]

[tex](b)\ \sigma_y = 300[/tex]

Step-by-step explanation:

Given

[tex]\mu_x = 75[/tex] -- Mean of T-shirts

[tex]\sigma_x = 20[/tex] -- Standard deviation of T-shirts

[tex]Rate = \$ 15[/tex]

Solving (a): The mean of the revenue [tex](\mu_y)[/tex]

To solve this, we use:

[tex]\mu_y = Rate * \mu_x\\[/tex]

This gives:

[tex]\mu_y = 15 * 75[/tex]

[tex]\mu_y = 1125[/tex]

Solving (b): The standard deviation of the revenue [tex](\sigma_y)[/tex]

To solve this, we use:

[tex]\sigma_y = \sqrt{Rate^2 * \sigma_2^2}[/tex]

This gives:

[tex]\sigma_y = \sqrt{15^2 * 20^2}[/tex]

[tex]\sigma_y = \sqrt{90000}[/tex]

[tex]\sigma_y = 300[/tex]

Answer:

32 kilometers

Step-by-step explanation:

65 - 33 = 32 kilometers

Hope this helps

Answer:

b = 56km is the answer.

Step-by-step explanation:

a (Northbound train) = 33km

b (Eastbound train) = ?

c (Distance between them) = 65km

According to the Pythagorean theorem,

a² + b² = c²

33² + b² = 65²

1089 + b² = 4225

b² = 4225 - 1089

b² = 3136

b = 56km

∴ the eastbound train has travelled 56km.

Step-by-step explanation:

but look their is an aapp called MATH installed it and w you will get the answer

4. a) the sum of 30 and 100 is 130
100+30=130
$99. 100%
$X. 130%
X=99•130/100
X=12870/100
X=128.70$

4 b) If X is increased price
99•(130:100)=X
99•1.3=X
Equality:
99•(130:100)=99•1.3
99•1.3=99•1.3

5
a) AB=8X
Reduction of 40%
40%=4/10=2/5
AB’ =8X•2/5
AB’=16X/5

b) AC=6X
AC’ =6X•2/5
AC’=12X/5

c) CB? Can’t see the vector
CB= 2X+10
CB’ = 2X+10•2/5
CB’ = 2(2X+10)/5
CB’ = 4X+20/5

d) P of reduced triangle
P’ = AB’ + AC’ + CB’
P’ = 16X/5+12X/5+4X+20/5 all sides have same denominator of 5 therefore we can add them up,
P’ = 16X+12X+4X+20 all over 5
P’ = 32X+20/5=4(8X+5)/5

Good luck.

(Please help asap! Brainliest to best/correct answer)Read this argument from The New York Times opinion pages. Does the author of this article agree or disagree with Nadia Arumugam? Use evidence from each article to support your answer. Answer in a minimum of five sentences. (20 points)Mayor Michael Bloomberg has done a lot to help improve the health of New York City residents. Smoking is outlawed in workplaces, restaurants and bars. Trans fat is banned in restaurants. Chain restaurants are required to post calorie counts, allowing customers to make informed choices.Mr. Bloomberg, however, is overreaching with his new plan to ban the sale of sugary drinks larger than 16 ounces. He argues that prohibiting big drinks at restaurants, movie theaters, stadiums and other food sellers can help combat obesity. But as he admits, customers can get around the ban by purchasing two drinks.The administration should be focusing its energies on programs that educate and encourage people to make sound choices. For example, obesity rates have declined slightly among students in elementary and middle schools, with the city's initiatives to make lunches healthier with salad bars, lower-calorie drinks and water fountains in cafeterias. Requiring students to get more exercise has also helped.The city should keep up its tough anti-obesity advertising campaignsone ad shows that it takes walking from Union Square to Brooklyn to burn off the calories from a 20-ounce soda. The mayor has also started adult exercise programs and expanded the program for more fresh produce vendors around the city.Promoting healthy lifestyles is important. In the case of sugary drinks, a regular reminder that a 64-ounce cola has 780 calories should help. But too much nannying with a ban might well cause people to tune out.Citation: "A Ban Too Far."
