What is the answer for x?

Mathematics
1 answer:
vagabundo [1.1K]3 years ago
4 0

Answer:

x=5

Step-by-step explanation:

I first subtracted 88 from 180 because we know that 180 is the total degree of the three angles in a trangle. I got 92, then divided that by 2 since there are two angles that are unknown. I got 46, which I can then use to form the equation (9x+1)=46. I subtracted 1 from both sides to get rid of the 1 (since we're finding what x equals to), I then got 9x=45. After that, I divided 9 from both sides and got the answer x=5.

Hope this helped you : )

A company rents water tanks shaped like a cylinders. Each tank has a diameter of 12 feet and a height of 3 feet. The cost is $2
12345 [234]

Answer:

\$678.58

Step-by-step explanation:

step 1

<u>Find the volume of the tank</u>

we know that

The volume of a cylinder (water tank) is equal to

V=\pi r^{2}h

in this problem we have

r=12/2=6\ ft -----> the radius is half the diameter

h=3\ ft

substitute

V=\pi (6^{2})(3)=339.29\ ft^{3}

step 2

Find the cost

339.29\ ft^{3}*2\frac{\$}{ft^{3}}=\$678.58

MATH HELP???

<h2>Answer:</h2>

The quadratic function are:

 option: A   A)  y(y + 4) - y = 6

 Option: C   C.)  4b(b) = 0

<h2>Step-by-step explanation:</h2>

We know that the general equation of a quadratic equation in terms of a variable x is given by:

   ax^2+bx+c=0

A)

y(y + 4) - y = 6

On simplifying the terms we have:

   y^2+4y-y=6\\\\y^2+3y-6=0

Hence, option: A is correct.

B)

(3x + 2) + (6x - 1) = 0

(3x + 2) + (6x - 1) = 0\\\\i.e.\\\\3x+2+6x-1=0\\\\i.e.\\\\3x+6x+2-1=0\\\\i.e.\\\\9x+1=0

Hence, it is a linear equation.

Hence, option: B is incorrect.

C)

4b(b) = 0

it could also be written as:

4b^2=0

Hence, it is a quadratic equation.

Hence, option: C is correct.

D)

3a - 7 = 2(7a - 3)

3a-7 = 2(7a-3)\\\\i.e.\\\\3a-7=14a-6\\\\\\i.e.\\\\14a-6-3a+7=0\\\\i.e.\\\\14a-3a-6+7=0\\\\i.e.\\\\11a+1=0

which is again a linear equation.

Hence, option: D is incorrect.

Which is the graph of f(x) =3 sqrtx/4?
Ket [755]

Step-by-step explanation:

f(x) = 3√x /4

x=0 => y = 0

x=1 => y = 0.75

x=4 => y = 1.5 ==> (4, 1.5)

x=16=>y= 3

the right answer is the second graph
