Could some please help me with these two

Mathematics
1 answer:
damaskus [11]3 years ago
4 0

Answer:

+3

Step-by-step explanation:

(-m)^(-3) = -m^3, since (-1)^-3 = 1 / (-1).

If m = 2 then we have -2^(-3), or  -1 / [2^3]), or -1/8.

Finally, if n = -24, the original expression becomes

(-1/8)(-24) = +3

Second problem:  Only the first expression simplifies to a negative result.

Sphere A has a radius of 24 centimeters, and sphere B has a diameter of 42 centimeters. The radius of sphere A is multiplied by
Tamiku [17]

Answer:

7/8

Step-by-step explanation:

Sphere A has a radius of 24 centimeters, and sphere B has a diameter of 42 centimeters.

WE need find which factor is multiplied with radius of sphere A to produce the radius of sphere B

Diameter of sphere B is 42

Radius = diameter /2

Radius = 42/2= 21

Radius of sphere B = 21

RAdius of sphere A times x= radius of sphere B

24 * x= 21

Divide by 24 on both sides

x= 21/ 24

divide top and bottom by 3

x= 7/ 8

If z=3 and z*y=12 what does y+5 equal
mart [117]
Z = 3                                              (This equation is a given)

z(y) = 12                                       ( This equation is also given) 

3y = 12                                         (as z = 3, plug 3 into z)

3y/3 = 12/3                                   (isolate the y by dividing 3 to both sides) 
                                                  * you divide 3 to both sides because of the equal                                                             sign. What you do to one side you do to the                                                                    other
y = 4                                             (answer for y)

y + 5                                             (what you are solving for)

(4) + 5 = 9                                    (As y = 4, plug in 4 for y in this equation)

y + 5 = 9                                       (4 + 5 =  9, or addition property)

9 is your answer           

hope this helps
