If a >b, then ac> bc true or false?

Mathematics
1 answer:
Verdich [7]2 years ago
5 0

Answer:

False

Step-by-step explanation:

a>b

Let c> 0 then ac>bc because we are multiplying by a positive number

if c<0  then ac < bc because we are multiplying by a negative number we have to flip the inequality symbol

Since we do not know the value of c, we have to go with false

When having the same radius and height what fraction of a cylinder have the same volume as one cone?
trasher [3.6K]

Answer:

1/3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone = 1/3(nr^2h)

n = 22/7

r = radius  

h = height

If the volume of a cylinder is 300, the volume of a cone = 1/3 x 300 = 100

the capacity of a cone is 1/3 that of a cylinder

adelina 88 [10]

The answer is Internal Validity.

Internal Validity is high in an experiment. when it demonstrates persuasively that changes in behavior are caused by the independent variable and not by unknown factors.

What is Internal Validity?

  • Internal validity is defined as the degree to which the observed results represent the truth in the population under investigation and are not the consequence of methodological flaws.
  • Internal validity is the degree of certainty that the causal link being examined is reliable and unaffected by other factors or variables.
  • The extent to which study results may be extended (generalized) to other contexts, groups, or events is referred to as external validity.

in order to solve the system of equations below , harvey multiplies each equation by a constant to eliminate the x terms.
kicyunya [14]

Answer:

14x + 6y = 10 \\  - 14x - 35y = 77

multiply all terms in the top equation by 2

multiply all terms in the second equation by -7. it would then add the two equations together to cancel out the variable x

You will then have two equations in terms of y

solve for y and either equation then substitute that value for y into the other equation then solve for x
