Answer:

The answer is 8.

Step-by-step explanation:

Plugging in n and m in the equation, we have,

0.1 * (30) + 8 - (12) * (1/4) = ? → equation 1

Then we apply PEMDAS to solve.

Solve 0.1 * 30 first; 0.1*30 = 3

Then 12 * 1/4; 12 * 1/4 = 3

Put the values from above to equation 1

Now we have 3 + 8 - 3 = ?

Keeping the PEMDAS in mind, addition first before subtraction.

3 + 8 = 11

11 - 3 = 8

Therefore the answer is 8.

Answer:

Step-by-step explanation:

All you need to do is plug in m and n.

m=30

n=1/4

0.1m+8-12n

0.1(30)+8-12(1/4)=8

Translate each of the following English statements into logical expressions. The domain of discourse is the set of all real numb

Scilla [17]

Answer:

A) З x,y : ( x/y < 1, y/x < 1 )

B) ∀ Y : ( Y > 0 = 1/Y > 0 )

C) з x,y : ( x+y = xy )

D) ∀ x,y : [ ( x>0 ) ∧( y > 0 ) = (( x/y > 0 ) ∧ ( y/x > 0 ))

E ) ∀ y : [ ( y > 0 ) ∧ ( y < 1) = ( 1 / y > 1 )

F) <em>n</em> ( ( з x ∀ y ( x <y ) )

G) ∀x (( x ≠ 0 ) = ( зy ( xy = 1 ) ))

H) ∀x ( (x≠0) = ( з! y (xy = 1))

Step-by-step explanation:

since the domain of discourse is a set of all real numbers the logical expressions of the English statements are expressed with respect to real number:

A) З x,y : ( x/y < 1, y/x < 1 )

B) ∀ Y : ( Y > 0 = 1/Y > 0 )

C) з x,y : ( x+y = xy )

D) ∀ x,y : [ ( x>0 ) ∧( y > 0 ) = (( x/y > 0 ) ∧ ( y/x > 0 ))

E ) ∀ y : [ ( y > 0 ) ∧ ( y < 1) = ( 1 / y > 1 )

F) <em>n</em> ( ( з x ∀ y ( x <y ) )

G) ∀x (( x ≠ 0 ) = ( зy ( xy = 1 ) ))

H) ∀x ( (x≠0) = ( з! y (xy = 1))

Age Problem. Please help. I suck at these.

eimsori [14]

Let Cynthia's age be C, then Abigail's age A

since Abigail is 8 years older, her age A = C+8.

20 years ago Cynthia's she was C-20 and Abigail was A-20=3(C-20)

A-20=3C-60
A=3C-40
but we just said A=C+8
so 3C-40=C+8
2C=48
C=24
A=24+8=32

Cynthia's age is 24 and Abigail's age is 32

For a given rabbit population, the relationship between the number of adult female rabbits, F, and the number of offspring, R, t

Sphinxa [80]

Considering the given function in the problem, it is found that:

a. 9.6 offspring survive to maturity when there are 12 female rabbits in the population.

b. At least 18 female rabbits are required for there to be 13 offspring.

<h3>What is the given function in this problem?</h3>

The function gives the relationship between the number of adult female rabbits F and the number of offspring R as follows:

$R = 3 + \frac{350F}{F + 625}$

When there are 12 female rabbits, we have that F = 12, hence:

$R = 3 + \frac{350 \times 12}{12 + 625} = 9.6$

9.6 offspring survive to maturity when there are 12 female rabbits in the population.

For at least 13 offspring, we have that the number of rabbits needed is given as follows:

$R \geq 13$

$3 + \frac{350F}{F + 625} \geq 13$

$\frac{350F}{F + 625} \geq 10$

$350F \geq 10F + 6250$

$F \geq \frac{6250}{340}$

$F \geq 18$

At least 18 female rabbits are required for there to be 13 offspring.

Solve by substitution. <br> 3x-y=5<br> -2x+y=0

Citrus2011 [14]

In order to use substitution, you need to isolate a variable on one of the equations:

-2x+y=0
y=2x

Then you plug that equation into the other equation. Since we isolated y, we plug in 2x for y in the other equation:

3x-(2x)=5
x=5

Then plug the value you found into any equation to solve for the other variable:

3(5)-y=5
15-y=5
-y=-10
y=10

So your answers are x=5, y=10
