Well

1 cg (centigram) is the same as 10 mg (milligrams)

so

25 milligrams are lighter

1 centigram= 10 milligram

if you convert 25cg to mg, you'll get 250mg (25×10)
so 25 mg is lighter than 25cg(250mg)

so your answer is 25mg is lighter than 25cg.

If f(x)=5x^2 and g(x)=x+1 find (f•g)

LenKa [72]

(f•g)= f(1)•g(1)

= 5(1)^2 • (1)+1

= 5(1) • 2

= 5 • 2

= 10

Your answer here is 10.

Hope I helped!

PLZ HLP Given the equation 5x + y = 7, which equation below would cause a consistent-independent system?

DanielleElmas [232]

Answer:

the equation D ) would cause a consistent-independent system.

Step-by-step explanation:

A ) 5 x + y = 7 /*( -2 )

10 x + 2 y = 14

--------------------

- 10 x - 2 y = - 14

10 x + 2 y = 14

------------------------

0 x = 0 ( Dependent system )

B ) 5 x + y = 7 / * 3

- 15 x - 3 y = - 6

--------------------------

15 x + 3 y = 21

- 15 x - 3 y = - 6

-------------------------

0 x = 15 ( Inconsistent system )

C ) 5 x + y = 7

5 x + y = - 7 / * ( - 1 )

---------------------------

5 x + y = 7

- 5 x - y = 7

------------------

0 x = 14 ( Inconsistent system )

D ) 5 x + y = 7 / * ( - 2 )

6 x + 2 y = 7

------------------

- 10 x - 2 y = - 14

6 x + 2 y = 7

-----------------------

- 4 x = - 7; x = 7/4; y = - 7/4

A gift shop sells 140 wind chimes per month at $90 each. The owners estimate that for each $5 increase in price, they will sell

guapka [62]

Answer: $95

Step-by-step explanation:

Te new price will be 90 + 5x, if the price increases "x" times

The number of wind chimes sold per month will become 140 - 7x

$\begin{aligned}&\text {Revenue, } \mathrm{R}(\mathrm{x})=(90+5 \mathrm{x})(140-7 \mathrm{x}) \\&R^{\prime}(x)=5(140-7 x)-7(90+5 x) \\&R^{\prime}(x)=700-35 x-630-35 x \\&R^{\prime}(x)=70-70 x=0 \\&70 x=70 \\&x=1\end{aligned}$

Therefore, if the price becomes (90 + 5(1)) = $95 per wind chime, then the revenue will be maximum

Rewrite each of the following statements in the form "∀ _____ x, _____." (a) All dinosaurs are extinct. ∀ x, . (b) Every real nu

jasenka [17]

Answer:

See below

Step-by-step explanation:

Essentially, we have to replace "quantifier words" like "All", "Every" by the universal quantifier ∀.

a) ∀ dinosaur x, x is extinct.

b) ∀ real number x, x is positive, negative, or zero.

c) ∀ irrational number x, x is not an integer.

d) ∀ logician x, x is not lazy.

e) ∀ integer x, x²≠ 2,147,581,953.

f) ∀ real number x, x²≠ -1.

In a) and b) we replace the words without major changes. In the other statements, we modify the statement using negation. For example, "No irrational numbers are integers." is equivalent to "Every irrational number is not integer".
