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)

Answer: The answer is k= -9

Step-by-step explanation:

this is how you solve it :

-8+k=-17

so then you add 8 to both sides so it would look like

-8+k+8=-17+8

then you simplify

after you simplify it would equal k=-9

THATS ALL :) have a good day

also could you please make me brainleast ???

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.

The correct option is A. Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

There are four types of rigid motions that we will consider translation , rotation, reflection, and glide reflection.

Here we have to rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

Hence option A is correct that is Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

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

-8 - -8 = 0

So the slope is -1 over 0

Answer:

138 of the students are boys, and 162 of them are girls. there are 24 more girls than boys.

Step-by-step explanation:

multiplying a number by its percent as a decimal gets you the percent of that number

300 x .46 = 138 boys

now subtract that from the original 300 to get the girls

300 - 138 = 162 girls

lastly subtract the girls from the boys to get how many more girls there are than boys

162 - 138 = 24

Answer:

The total number of planes = 23 planes

Step-by-step explanation:

The number of planes are give as follows;

The number of planes with three points, given that any three points of an octahedron forms a plane are ₆C₃ = 20

The number of distinct planes that has 4 points in the octahedron = 3

Therefore, the total number of planes are 20 + 3 = 23 planes.

Answer:

The pencil is £1 and the pen is £2

Step-by-step explanation:

Let the pencil be p and let the pen be f.

5p + 3f = 11

4p + 6f = 16

the top one multiplies by two:

10p + 6f = 22

4p + 6f = 16    subtract

6p = £6

pencil = £1

Then you substitute the value of the pencil into the equation and find the value of the pen.

Answer:

5p-6q or 5p+ (-6q)

If you are looking to create one equation, then combine like terms.

2p+3p and -5q + (-q or 1)

5p and -6q

5p-6q or 5p+ (-6q)

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.

Hope this helps! :D

Answer:

.125 or 1/8

Step-by-step explanation:

The question is looking for the difference divided by the long ride. The long ride is 6 1/4 miles, so now we need to find the difference.

In order to do this, we take the larger distance and subtract the smaller distance.

We would take (Tip: Use decimals when you can. They are easier to work with ) 6.25 - 5.5 and we get .75 or 3/4 of a mile.

Now, we put .75 over 6.25 and simplify.

.125 or 1/8

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
