Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answers
Answer:
Perimeter is 12mm, height is [tex]2\sqrt3[/tex]mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem ([tex]a^2+b^2=c^2[/tex]) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.
Hope this helps!

Answer: D. Acutes Isosceles
Step-by-step explanation:
Two sides of the triangle are equal making an isosceles triangle. Also most of the angles on the triangle are acute, therefore it can referred to as an Acute Isosceles triangle.
(You owe me brainliest)
Answer:
Acute Isosceles
Explanation:
Option 1. We can eliminate the first option since it's also an isosceles triangle(a triangle with two equal sides)
Option 2. It is an isosceles triangle although it is a right angled triangle (An angle with at least one 90 degree angle)
Option 3. it isn't an obtuse angled triangle since it has no angles that are greater than measure more than 90 degrees.
That leaves Option 4 which is our answer since it says that the triangle is both isosceles and acute(an angle less than 90 degrees)

Gabriella goes to a store and buys an item that costs x dollars. She has a coupon for 35% off, and then a 8% tax is added to the discounted price. Write an expression in terms of x that represents the total amount that Gabriella paid at the register.
Answers
Answer:
0.702x
Step-by-step explanation:
Let's first find the discounted price Gabriella received with the 35% off coupon:
Discounted price = x - (0.35 * x)
Now, let's calculate the 8% tax on this discounted price:
Tax = 0.08 * (x - 0.35x)
Finally, let's add the tax to the discounted price to find the total amount Gabriella paid at the register:
Total = (x - 0.35x) + 0.08(x - 0.35x)
Simplifying the expression:
Total = x(1 - 0.35) + 0.08(x - 0.35x)
Total = 0.65x + 0.08x - 0.028x
Total = 0.702x
Therefore, the expression that represents the total amount Gabriella paid at the register is 0.702x.
Answer: 0.702x
Step-by-step explanation:
Discounted price = x - (0.35 * x)
Now, let's calculate the 8% tax on this discounted price:
Tax = 0.08 * (x - 0.35x)
Finally, let's add the tax to the discounted price to find the total amount Gabriella paid at the register:
Total = (x - 0.35x) + 0.08(x - 0.35x)
Simplifying the expression:Total = x(1 - 0.35) + 0.08(x - 0.35x)
Total = 0.65x + 0.08x - 0.028
xTotal = 0.702x

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $1800 and his stock in Company B was worth $1930. The stock in Company A has decreased 16% since last year and the stock in Company B has decreased 20%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Answer:
18.4 is most likely the answer
The new value of the stock in Company A is:
0.84 x $1800 = $1512
Similarly, the new value of the stock in Company B after the decrease of 20% is:
0.8 x $1930 = $1544
The total value of the investor's stock account now is:
$1512 + $1544 = $3056
To find the percentage decrease in the investor's stock account, we need to compare the total value of the account now to the total value of the account last year:
($1800 + $1930) = $3730
The percentage decrease is:
[(3730 - 3056)/3730] x 100% ≈ 18.1%
Therefore, the total percentage decrease in the investor's stock account is approximately 18.1%.

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6100 and his stock in Company B was worth $6480. The stock in Company A has decreased 2% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Investment in Company A by investor = $6100
Investment in Company B by investor = $6480
The decrease in value of the stock of company A is 2%
The decrease in value of the stock of company B is 10%
Value of wealth that investor lost in company A = 6100× 2/100
= 61×2
= $122
The decline in the value of the stock of company B = 6480×10/100
= 648×1/1
= $648
The total decline in the wealth of the investor= 122+648
= $770
The combined wealth of investor in both companies= 6100+6480
= $12580
Percentage of decline in the stock account of investor= 770×100/12580
= 77000/12580
= 6.1%
The total percentage decline in investor's stock account is 6.1%

A spinner is divided into five sections, labeled A, B, C, D, and E. Devon spins the spinner 50 times and records the results in the table.
Based on the table above, make a prediction for 200 trials.
Answers
Answer:
Prediction for 200 trials: A- 40 times, B- 56 times, C- 48 times, D- 32 times, E- 24 times
Step-by-step explanation:
A=10/50=1/5 (then multiply by 200)
B=14/50=7/25 (then multiply by 200)
C=12/50=6/25 (then multiply by 200)
D=8/50=4/25 (then multiply by 200)
E=6/50=3/25 (then multiply by 200)
In the 50 trials, we see that section A occurred 9 times out of 50, or 18% of the time. Similarly, section B occurred 10 times out of 50, or 20% of the time. Section C occurred 15 times out of 50, or 30% of the time. Section D occurred 8 times out of 50, or 16% of the time. Finally, section E occurred 8 times out of 50, or 16% of the time.
Assuming that the same proportion holds for 200 trials, we can predict the number of occurrences for each section as follows:
- A: 0.18 x 200 = 36 occurrences
- B: 0.20 x 200 = 40 occurrences
- C: 0.30 x 200 = 60 occurrences
- D: 0.16 x 200 = 32 occurrences
- E: 0.16 x 200 = 32 occurrences
Therefore, based on the table above, we can predict that in 200 trials, section C will occur the most frequently (60 times), followed by section B (40 times), section A (36 times), and sections D and E equally (32 times each). It's important to note that this is just a prediction based on the observed data, and the actual results may vary due to chance.
Reena has a square office with an area of 126 square feet. Jazmine has a square office with an area that is 50% greater than the area of Reena’s office. To the nearest tenth, how much greater is the side length of Jazmine’s office than the side length of Reena’s office?
Answers
Answer:
Reena has a square office with an area of 126 square feet. Jazmine has a square office with an area that is 50% greater than the area of Reena’s office. To the nearest tenth, how much greater is the side length of Jazmine’s office than the side length of Reena’s office?
To find the side length of Jazmine's office, we need to first determine the area of her office. We know that her office has an area that is 50% greater than Reena's office, which means the area of Jazmine's office can be calculated as follows:
Area of Jazmine's office = (1 + 0.5) * Area of Reena's office Area of Jazmine's office = 1.5 * 126 square feet Area of Jazmine's office = 189 square feet
Since Jazmine's office is also square, we can find the side length by taking the square root of the area:
Side length of Jazmine's office = sqrt(189) feet Side length of Jazmine's office ≈ 13.7 feet
To find how much greater the side length of Jazmine's office is than the side length of Reena's office, we simply subtract the side length of Reena's office (which is also the square root of her office's area) from the side length of Jazmine's office:
Side length difference = Side length of Jazmine's office - Side length of Reena's office Side length difference = sqrt(189) feet - sqrt(126) feet Side length difference ≈ 1.8 feet
Therefore, to the nearest tenth, the side length of Jazmine's office is 1.8 feet greater than the side length of Reena's office.

1.8 feet greater than the side length of Reena's office

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6680 and his stock in Company B was worth $4660. The stock in Company A has decreased 20% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Answer:
$6,680 + $4,660 = $11,340
$6,680(.8) + $4,660(.9) = $9,538
1 - $9,538/$11,340 = .159 = 15.9%
The total percentage decrease in the investor's stock account was 15.9%.
The total percentage decrease in the investor's stock account was 15.9%.
Total stock value of both companies A and B = $6680 + $4660 = $11340.
Previous year's stock of company A = $6680
Total decrease on company A's stock = 6680×20/100 = 1336.
Previous year's stock of company B= $4660
Total decrease on company B' stock = 4660 × 10/100 = 466.
Total decrease in stock's value = Stock value of company A + Stock value of company B.
=1336 + 466 = 1802
Total percentage of decrease = 1802 × 11340 / 100
So, total percentage of decrease of investor for both the companies = 15.89%.
Therefore the total percentage decrease in the investor's stock account will be 15.9%.
