The length of the base of an isosceles triangle is x. The length of a leg is 3x - 4. The perimeter of the triangle is 76. Find x.
X=

Answers

Answer:

12

Step-by-step explanation:

Hi!

We're given that the perimeter is 76. A triangle's perimeter is given by the sum of all of the sides. So, we'll find the lengths of the sides of the triangle and add them.

This is an isosceles triangle. The legs of an isosceles triangle are equal. In this problem, we're given the length of one leg: 3x-4. That means that the length of the other leg is also 3x-4. Now, the last side of the triangle is x ("base is x).

2(3x-4) + x = 76

6x-8+x=76

7x-8=76

7x=84

x=12

Let's check our answer.

3(12) - 4 =36-4 = 32

32 times 2 = 64 +12 =76

Correct!

Answers

Answer:

1

Step-by-step explanation:

A teacher administers a standardized math test to his class of 75 students. The mean score (out of 300 possible points) is 235. From previous studies, you know the population standard deviation is 28. Using the sample data given, calculate a 95% confidence interval for the population mean.

Answers

Answer:

(228.663 ; 241.337)

Step-by-step explanation:

Given that:

Mean (m) = 235

Standard deviation (s) = 28

α = 95%

Zcritical at 95% = 1.96

Sample size (n) = 75

The confidence interval of the population mean can be obtained using the relation :

Mean ± Error

Error = Zcritical * (s/sqrt(n))

Error = 1.96 * (28/sqrt(75))

Error = 1.96 * 3.2331615

Error = 6.33699654

Error = 6.337

Lower boundary = 235 - 6.337 = 228.663

Upper boundary = 235 + 6.337 = 241.337

(228.663 ; 241.337)

So we have to satisfy the equation so let us simplifyLet the empty space be n N-16+4n+9+1= 10n-6 N-4n=10nn=14n So the missing value is 14N to statify the equation
Let the blue line equal to n

So now the equation is n-16+4n+10=10n-6

Collect like terms

5n-6= 10n-6

Move 6 to the other side as a positive

5n=10n

Move 10n to the other side as a negative

5n-10n=0

-5n=0

Divide both sides by -5

So, n is equal to 0

Answers

Answer:

The answer is 81°

Step-by-step explaination:

To start, the top right angle and the bottom left angle are alternate interior angles, making them congruent. The same justification goes for the angles in the top left and bottom right. With this in mind, 37° + 44° = 81°. Every triangle's angles always add up to 180°, meaning that 180° - 81° = 99°. Because angle n and the angle we just found to be 99° are supplementary, they also add up to 180°, therefore 180° - 99° = 81° which is the value of angle n.

Which graph represents the equation (x – 1)2 + (y + 1)2 = 9?

Answers

Answer:

D

Step-by-step explanation:

The given equation  (x – 1)² + (y + 1)² = 9 represents a circle with the center (1, -1) and a radius of 3.

What are the properties of the circle?

The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.

Given an equation  (x – 1)² + (y + 1)² = 9

The general coordinate equation of a circle is:

(x-h)² + (y - k)² = r²

Where,

(h, k) is the center of a circle,

"r" is the radius of the circle.

Comparing with the general equation of a circle:

h = 1,

k = -1

r² = 9

r = 3

thus, the given equation  (x – 1)² + (y + 1)² = 9 represents a circle with the centre (1, -1) and the radius of 3.

The Tierney Group has two divisions of equal size: an office furniture manufacturing division and a data processing division. Its CFO believes that stand-alone data processor companies typically have a WACC of 9%, while stand-alone furniture manufacturers typically have a 13% WACC. She also believes that the data processing and manufacturing divisions have the same risk as their typical peers. Consequently, she estimates that the composite, or corporate, WACC is 11%. A consultant has suggested using a 9% hurdle rate for the data processing division and a 13% hurdle rate for the manufacturing division. However, the CFO disagrees, and she has assigned an 11% WACC to all projects in both divisions. Which of the following statements is CORRECT?A. The decision not to adjust for risk means, in effect, that it is favoring the data processing division. Therefore, that division is likely to become a larger part of the consolidated company over time.B. The decision not to adjust for risk means that the company will accept too many projects in the manufacturing division and too few in the data processing division. This will lead to a reduction in the firm's intrinsic value over time.C. The decision not to risk-adjust means that the company will accept too many projects in the data processing business and too few projects in the manufacturing business. This will lead to a reduction in its intrinsic value over time.D. The decision not to risk-adjust means that the company will accept too many projects in the manufacturing business and too few projects in the data processing business. This may affect the firm's capital structure but it will not affect its intrinsic value.E. While the decision to use just one WACC will result in its accepting more projects in the manufacturing division and fewer projects in its data processing division than if it followed the consultant's recommendation, this should not affect the firm's intrinsic value. a school population of 1200 increases by 6% per year what will the population be after 4 years
