Answer 1

No these triangles are not similar.

Step-by-step explanation:

Given Information on First triangle :

Base = 3

Height = 8

Given information on Second triangle :

Base = 4

Height = 10

Area of a Right Angle triangle :

[tex] \frac{base \times height}{2} [/tex]

Area of First triangle :

[tex] \frac{3 \times 8}{2} = \frac{24}{2} \\ \\ = 12[/tex]

Area of Second triangle :

[tex] \frac{4 \times 10}{2} = \frac{40}{2} = 20[/tex]

Their Ratio :

[tex]12:20 = \frac{12}{20} \\ = \frac{3}{5} [/tex]

So I guess no, the triangles are not similar.

1. a rectangular room measures 10 feet by 12 feet. What is the area of the room?

2. What is the area of a rectangle with a base of 6 inches and height of 10 inches?

3. Travis is planting a rectangular garden that is 5 feet by 12 feet. One bag of soul covers 6 square feet. How many bags of soil does he need to cover the whole garden?

PLEASE HELP! PLEASE HELP!

Answers

Answers:

Area = 120 square feetArea = 60 square inchesHe needs 10 bags

==================================================

Explanation:

For problems 1 and 2, we just multiply the base and height. This is the same as multiplying the length and width.

So in problem 1 we have 10*12 = 120 square feet. In problem 2 we have 6*10 = 60 square inches.

-----------------------

Problem 3 follows the same idea, but we do a bit more work. The area of the garden is 5*12 = 60 square feet.

Let's say x is the number of bags needed.

1 bag covers 6 square feet

2 bags cover 12 square feet

and so on

x of those bags cover 6x square feet. The x is just a placeholder for a number. Specifically, a positive whole number.

The expression 6x represents how much area that can be covered by x bags. We want to cover 60 square feet.

The equation we need to solve is 6x = 60. Doing so leads to x = 10 after dividing both sides by 6.

So this means Travis needs 10 bags.

Answers

Answer: 276

Step-by-step explanation:

multiply 1/3 by 4/4 to make it similar to 5/12 that way you can add them. because the denominator is different from each other you can’t add them. once you do that you get 4/12, you then add 5/12 and that equals 9/12. in order to get to 12/12 you need 3/12 more. this 3/12 represents the 69 guest that chose vegetarian. the 5/12 represents the the guest who chose chicken and the 4/12 represents the ones who chose beef. now that you know 69 people is the same as 3/12 of all the guest. you then realize that 9 is divisible by 3. so you multiply 69 by 3 because 3 goes into 9 3 times. which gives you 207. 207 represents 9/12. and we already know 69 represents 3/12. so you add them together and get 276. sorry if that was confusing but that’s the best way i can explain it.

A quantity with an initial value of 8100 decays continuously at a rate of 0.95% per year. What is the value of the quantity after 96 months, to the nearest hundredth?

Answers

Answer:

20163.299

Step-by-step explanation:

Initial value = 8100

Rate r = 0.95% = 0.0095

t = 96 month

Therefore, Value of the quantity after 39 decades = Initial value*e^(rt)

= 8100*e^(0.0095*96)

= 8100*e^(0.912)

= 8100*2.48929615041

= 20163.298818321

= 20163.299

So, the value of the quantity after 96 months is 20163.299
