Subtract 8 feet from 9 yards, 1 foot
Advocard [28]

Answer:

20 feet

Step-by-step explanation:

There are 3 feet in a yard, so 9 yards and 1 foot = 28 feet. You find this by multiplying 9x3 = 27 and adding the extra foot, which makes it 28. To find the final answer just subtract 8 from 28, which gives you 20.

QF Q6.) Find the function for a.
irakobra [83]
The function for a is (f o g) (x) = 8x^2-10.



Explanation

=========================
f(x)=2x-4, g(x)=4x^2-3, (f o g)=f(g(x))  

I already knew that the g of x is equal to 4x^2-3 so I substitute inside of the g of x

g(x)=4x^2-3 =======> f(x)=4x^2-3 =============> 2(4x^2-3)-4 

simplify it 
 
2(4x^2-3)-4  =======> 8x^2-6-4 =========> 8x^2-10

(f o g) = 8x^2-10

The measures of a triangle are in the ratio 2:3:5. what are the measures of the angles?
xxTIMURxx [149]

9514 1404 393

Answer:

  36°, 54°, 90°

Step-by-step explanation:

We have to assume that the given measures are <em>angle</em> ratios, not <em>side</em> ratios. Sides in the ratios 2:3:5 will not form a triangle.

For some multiplier x, the angle values will total 180°.

  2x +3x +5x = 180

  x = 180/(2+3+5) = 18

Then the angle measures are ...

  2x° = 2·18° = 36°

  3x° = 3·18° = 54°

  5x° = 5·18° = 90°

The angle measures are 36°, 54°, and 90°.
