Which equation has solutions of 6 and -6

Pani-rosa [81]

I don't see any answers provided so, i'm going to add, subtract, multiply, and divide with 6 and -6.

6 + -6 = 0 | Another solution: Any number multiplied by 0

6 - (-6) = 12 | Another Solution: 6 + 6

6 · -6 = -36 | Another Solution: -6 squared

6 / -6 = -1 | Another Solution: -1 x 1

Uca is designing a propeller system that consists of 3 blades, each of which is

zmey [24]

Answer:

The weight of the three blades together is $134\ g$

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=4\ in$

assume

$\pi=3.14$

substitute

$A=(3.14)(4)^{2}$

$A=50.24\ in^{2}$

step 2

Find the area of the 3 blades

we know that

The area of the 3 blades represent a central angle of 60 degrees, so

its a 1/6 of the area of complete circle

$A=50.24/6=8.37\ in^{2}$

step 3

Find the weight of the three blades together to the nearest gram

$(8.37\ in^{2})*(16\ g/in^{2})=134\ g$

Answer:

A. 11160 cubes B. 1395cm^3

Step-by-step explanation:

Volume= length x width x height

Its easiest to solve B. first and use it to solve A.

B. 7.5 x 12 x 15.5 = 1395cm^3 (volume of prism)

A. .5 x .5 x .5 = 1/8cm^3 (which is the volume of the cube)

1395 ÷ 1/8 = 11160
