Find the value of x

bearhunter [10]

Answer:

x=66

Step-by-step explanation:

A straight line is equal to 180 degrees so we can make the equation 180=2x-48. After this we can do 180-48=2x then we can do 132/2=x

Two spheres have radii 6 and 15. Find the ratios of the areas and the volumes.

lina2011 [118]

Answer:

1st sphere has r1 = 6

=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 6^2 = 144pi

=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 6^3 =288pi

2nd sphere has r1 = 15

=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 15^2 = 900pi

=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 15^3 =4500pi

=> S1/S2 = 144pi/900pi = 0.16

=> V1/V2 = 288pi/4500pi = 0.064

Hope this helps!

Trees are being planted in an area of land that measures approximately three acres. One acre contains 43,560 square feet, if one

kobusy [5.1K]

1 yard = 3 feet, so 2yds x 1yd is the same as 6ft x 3ft, or 18 square feet

If one acre contains 43,560 square feet, and the question asks how many trees can be planted per acre, then all we have to do is divide 43,560 by 18:

43,560 ÷ 18 = 2420 trees

So, the answer is A) 2,420.

Which of the following systems is dependent? x − y = 2 and x + y = −2 x − y = 2 and −2x + 2y = −4 x − y = 2 and 3x − 3y = 2 x −

hram777 [196]

A system is linearly dependent, when multiplying one of the equations by a scalar, you get the other equation.
We then have the following system of equations:
$x - y = 2

-2x + 2y = -4$
Let's rewrite the system of equations.
To do this, let's multiply equation 1 by scalar -2:
$-2x - (-2) y = (-2) 2

-2x + 2y = -4$
We observe that we obtain equation 2 of the system.
Therefore, the system is linearly dependent.
Answer:
the following system is dependent:
x - y = 2 and -2x + 2y = -4
