•) Change both denominators to twelve since 12 goes into 3 4 times. Now, add 7+2. The answer is 9. 9/12 can be simplified. Divide 9/3 and 12/3. Your answer is 3/4.

A group of friends were working on a student film that had a budget of $1140. They used 65% of their budget on costumes. How muc
Stells [14]

Answer:

They use 741 dollars

Step-by-step explanation:

Write 65% as

65/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

65/100 of 1140 = 65/100× 1140

Therefore, the answer is 741

If you are using a calculator, simply enter 65÷100×1140 which will give you 741 as the answer.

The ratio of the side lengths triangle is 7:24:29 and it’s perimeter is 180 m. What are the side lengths of the triangle? Select
kakasveta [241]
Answer: Only 21:72:87


Explanation: We know that the side lengths are not simply 7, 24, and 29, as the sum of these is only 60.


Therefore, we need to find the scale factor they were multiplied by to have side lengths with a sum of 180.

We can use 7x+24x+29x=180.

This becomes 60x=180 and the scale factor is x=3.

7*3=21, 24*3=72, and 29*3=87.

Choose the correct conic section to match the equation. 16x 2 - y 2 = 16 parabola hyperbola ellipse circle
Nastasia [14]

The equation 16x² - y² = 16 represents a hyperbola ⇒ 2nd answer

Step-by-step explanation:

The general form of the equation of a conic is

Ax² + Bxy + Cy² + Dx + Ey + F = 0, where A, B, C, D, E, and F

are constants

To find the type of conic that the equation represent find B² - 4AC

1. B² - 4AC < 0 and the conic is exist, then it's ellipse or circle,

   if A = C, (non-zero) then it is a circle, if A ≠ C, then it is an ellipse

2. B² - 4AC = 0 and the conic is exist, then it's a parabola

3. B² - 4AC > 0 and the conic is exist, then it's a hyperbola

∵ The equation is 16x² - y² = 16

- Subtract 16 from both sides

∴ 16x² - y² - 16 = 0

∵ Ax² + Bxy + Cy² + Dx + Ey + F = 0

∴ A = 16 , B = 0 , C = -1 , D = 0 , E = 0 , F = -16

∵ B² - 4AC = (0)² - 4(16)(-1)

∴ B² - 4AC = 64

∵ 64 > 0

∵ B² - 4AC > 0

∴ The conic is hyperbola

The equation 16x² - y² = 16 represents a hyperbola
