What is the value of x?

1 answer:

3 0

In a right triangle, the hypotenuse is √2 x the legs. In this case, the value of x is $\frac{18}{\sqrt{2} } =\frac{18\sqrt{2} }{2} =9\sqrt{2}$ .

Lines L and K are parallel to each other. Measure of angle A= 120 degrees, and measure of angle C= 80 degrees. What is the numbe

ale4655 [162]

Answer:

160°

Step-by-step explanation:

The way I am doing it may not be the correct way but it works. What I did was take 90° away from 120° to make it 30° as if there is a line. I did this so I could make a triangle. Using the triangle addition postulate, I Added 30 to 80 to get 110 than subtracted that from 180 to get 70. Lastly, i added 90° to 70° to get 160°

Hope this helped you get the answer :)

David brought a variety pack of delicious donuts for his daughters Amy & Anna. Amy ate 2/3 of the pack and Anna devoured 1/4

Naya [18.7K]

Answer:

Step-by-step explanation:

Let the total number of donuts in the pack be x.

Amy = 2/3x

Anna = 1/4x

David = 1

x - 2/3x - 1/4x = 1

Find common denominators for 2/3 and 1/4

The common denominator is 12

2/3 * 4/4 = 8/12

1/4 * 3/3 = 3/12

x - 8/12x - 3/12x = 1

x - 11/12x = 1

1/12x = 1

x = 12

You can always check

Amy = 8

Anna = 3

So David must equal to 1

Hope this helps :)

We want to find the zeros of this polynomial:

SCORPION-xisa [38]

Answer:

x=0 x=2 x=7/2

Step-by-step explanation:

P(x) = 3x (x - 2) (2x - 7)

Set equal to zero

0 = 3x (x - 2) (2x - 7)

Using the zero product property

3x =0 x-2 =0 2x-7 =0

x=0 x=2 2x=7

x=0 x=2 x=7/2
