Answer:

A. Total number of liters = 1.25 liters

B. Milk = 0.25 liters

Step-by-step explanation:

Let

x = total number of liters ( milk + water )

Milk = 20% of x

= 0.2x

Water = 1 liter

Total number of liters = milk + water

x = 0.2x + 1

x - 0.2x = 1

0.8x = 1

Divide both sides by 0.8

x = 1 / 0.8

= 1.25

x = 1.25 liters

Total number of liters = 1.25 liters

B.

Liters of milk in the bottle = Total number of liters - liters of water

= 1.25 liters - 1 liter

= 0.25 liter

Milk = 0.25 liters

[tex]\frac{-1}{0}[/tex] which is -1

Step-by-step explanation:

The slope formula is y2-y1 over x2-x1

So just plug it in. 2 - 3 = -1

-8 - -8 = 0

So the slope is -1 over 0

Step-by-step explanation:

1. have info for adjacent side and hypotenuse

so use; cosine

cos32=x/19

x=cos32×19

=15.9

2. have info for opposite side and hypotenuse

so use; sine

sin63=16/x

x=16/sin63

=95.6

3. have info for opposite side and adjacent side

so use; tangent

tan26=17/x

x=17/tan26

=14.4

4. have info for opposite side and adjacent side

so use tangent

tan42= x/13

x=tan42×13

x=29.8

Answer:

I think that the answer is A.

Step-by-step explanation:

The values that complete the table are -1/2, -√2/2 and -√3/2

The function is given as:

[tex]y = sin(x)[/tex]

From the table, we have:

sin(π) = 0

Next, we calculate the value of y for other values of x

When x = 7π/6, we have:

sin(7π/6) = -1/2

When x = 5π/4, we have:

sin(7π/6) = -√2/2

When x = 4π/3, we have:

sin(4π/3) = -√3/2

Hence, the values that complete the table are -1/2, -√2/2 and -√3/2

Answer:

The answer is yes!

Step-by-step explanation:

I'm 100% sure, put it into a calculator and it'll give you 1 as the answer.

Answer:

Yes

Step-by-step explanation:

The answer is yes because:

1) As you can see, in standard form the pattern is x * 3 = y

2) If x = 1 it would match the pattern because the next number will be 1 x 3 which is 3, and then the the third number would be 3 x 3 = 9, and then the fourth number would be 9 x 3 = 27 and so on.

Step-by-step explanation:

Answer:

The product st is irrational.

The product pt is irrational.

Step-by-step explanation:

Let p = 3/4 and q= 5/9

Now multiplying these two non zero rational numbers

3/4 (5/9)= 15/36 ( this is also a rational number)

An irrational number is one which cannot be expressed in the form of p/q where p and q are integers( in the form of a simple expression) like the rational number.

Now let the two irrational numbers  s and t be √3 and √5

Now multiplying the two irrational numbers we get

st = √3  √5

st =√15  ( this is also an irrational number)

√15 cannot be expressed in the form of a simple fraction.

Now multiplying pt

3/4 * √5= 3√5/4  ( this is also irrational)

Step-by-step explanation:

let x be the number of adults and y number of childrens

so we have. x+y=100 people

and. 12*x+8*y=1056 dollars

x=100-y

replace 100-y to the second equation

12*(100-y)+8y=1056

1200-12y+8y=1056

1200-4y=1055

1200-1056=4y

144=4y

y=144/4=36

so x=100-y=100-36=64

so in this group were 64 adults and 36 childrens

In this group were 64 adults and 36 children.

In mathematics, a system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.

let x be the number of adults and y number of children

so we have. x + y = 100 people

and. 12 × x + 8 × y = 1056 dollars

x=100 - y

replace 100 - y to the second equation

12 × (100 - y) + 8y = 1056

1200 - 12y + 8y = 1056

1200 - 4y = 1055

1200 - 1056 = 4y

144 = 4y

y = 144/4 = 36

so x = 100 - y = 100 - 36 = 64

Hence, in this group were 64 adults and 36 children.
