both the squareroot of 19 and 23 are irrational because their square toots have decimals that go on infinately

Answer:

3. - 8n² -8n + 3

Step-by-step explanation:

(4n^4 - 8n +4) - (8n² + 4n^4 +1)

Firstly, open the brackets.

= 4n^4 - 8n +4 - 8n² -  4n^4 - 1

Now, group like terms.

= 4n^4 - 4n^4 - 8n² -8n - 1 + 4

4n^4 - 4n^4 cancel out with each other since one is negative and the other is positive. So we're left with - 8n² -8n - 1 + 4

= - 8n² -8n - 1 + 4

= - 8n² -8n + 3

Answer:

42

Step-by-step explanation:

25+2(12)-7

25 + 24 - 7

49 - 7

42

[tex] \huge \color{Red} Answer: [/tex]

[tex]25 + 2(3 \times 4 ) - 7 = [/tex]

[tex]25 + 2 \times 12 - 7 = [/tex]

[tex]25 + 24 - 7 = [/tex]

[tex]49 - 7 = 42[/tex]

[tex] \huge \color{Blue} Explaination: [/tex]

First, Multiply the numbers inside the parentheses.

Second, Also Parentheses is also a Multiply sign so Multiply 12 and 2.

Third, Follow the left to right rule so add 25 and 24.

Lastly, Subtract the last number.

Answer:

4. AC = 36

5. m<UTW = 42

Step-by-step explanation:

4.

AB = BC

-x + 25 = 3(2x - 8)

-x + 25 = 6x - 24

-7x = -49

x = 7

AC = 2(-x + 25) = 2(-7 + 25) = 2(18) = 36

AC = 36

5.

2x + 3 = 5x - 24

-3x = -27

x = 9

m<UTW = 2m<UTV = 2(2x + 3) = 2[2(9) + 3] = 2(21) = 42

m<UTW = 42

Answer:

The answer is 9.

Step-by-step explanation:

2 squared = 4

4 + 5 = 9

Answer:

We have the sentence:

"X by the power of 5 times y to the power of 6 over 2 by the power of -2 times x by the power of 0times x by the power of 9"

Let's break it into parts.

"X by the power of 5 times y to the power of 6..."

This can be written as:

x^5*y^6

"...  2 by the power of -2 times x by the power of 0times x by the power of 9"

This can be written as:

2^(-2)*x^(0)*x^(9)

And we have the quotient between the first thing and the second thing, then the equation is:

[tex]\frac{x^5*y^6}{2^{-2}*x^0*x^9}[/tex]

And any number by the power of 0 is equal to 1, then:

x^0 = 1, then we can rewrite the equation as:

[tex]\frac{x^5*y^6}{2^{-2}*x^9}[/tex]

We can keep simplifying this.

We know that:

a^(-n) = (1/a)^(n)

Then:

2^(-2) = (1/2)^2 = 1/4

Then we get:

[tex]\frac{x^5*y^6}{2^{-2}*x^9} = \frac{x^5*y^6}{x^9}*4[/tex]

And we also know that:

a^n/a^m = a^(n - m)

Then:

[tex]\frac{x^5*y^6}{x^9}*4 = 4*y^6*\frac{x^5}{x^9} = 4*y^6*x^{5 - 9} = 4*y^6*x^{-4} = \frac{4*y^6}{x^4}[/tex]

And we can't simplify this anymore.

Answer: 8.3 m

Step-by-step explanation:

Given

The angle of declination is [tex]50^{\circ}[/tex]

Earthworm is [tex]7\ m[/tex] away from the base of the tree

Suppose h is the height of the tree

from the figure, we can write

[tex]\Rightarrow \tan 50^{\circ}=\dfrac{h}{7}\\\\\Rightarrow h=7\tan 50^{\circ}=8.3\ m[/tex]

Answer:

A. the degree is 4         11x^4-4x^2-12

B. The degree is 5        2x^5-3x^4+3x^3+7x+14

Step-by-step explanation:

The degree is always the highest or greatest exponent in the polynomial. To rearrange the polynomial put it in descending order from highest exponent to lowest exponent with x as an exponent of 1

Answer:

first one, and third one

Answer:

Greater than symbol.

2/3 > 2/4

Step-by-step explanation:

We have two fractions, 2/3 and 2/4

We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=).

Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given.

2/3 and 2/4

With 2/3 being greater than 2/4.

2/3 = 0.67

2/4 = 0.50

Succinctly, 2/3 > 2/4.

Answer:

20-6= 14

14 divided by 2 equals 7

he needs 7 more customers

Step-by-step explanation:

have a wonderful day! brainliest?

Answer:

B. (7)

Step-by-step explanation:

First, we figure out how many more items Joshua needs to sell so we do 20 - 6.

20 - 6 = 14.

Next, we do 14 / 2 because each customer buys 2 items.

14 / 2 = 7

Therefore, Joshua must have 7 additional customers to reach his goal.

Step-by-step explanation:

boys : girls

8 : 5

x : 75

to find x, take 75 and divide it by 5:

75 ÷ 5 = 15

(you do this to determine how you can go from 5 to 75)

take the qoutient and multiply it by 8:

15 × 8 = 180

Answer:

The amount of steel used = 94.38 [tex]m^{2}[/tex]

Step-by-step explanation:

Height of the tank = 4.5 m.

Diameter of the tank = 4.2 m.

But,

radius = [tex]\frac{diameter}{2}[/tex]

           = [tex]\frac{4.2}{2}[/tex]

radius  = 2.1 m

Total surface area of a cylinder = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]

                                      = 2[tex]\pi[/tex]r(r + h)

                                      = 2 x [tex]\frac{22}{7}[/tex] x 2.1 (2.1 + 4.5)

                                      = 44 x 0.3 (6.6)

                                      = 87.12

Total surface area of a cylinder = 87.12 [tex]m^{2}[/tex]

Since [tex]\frac{1}{12}[/tex] of the steel was wasted, then;

[tex]\frac{1}{12}[/tex] x 87.12 = 7.26 [tex]m^{2}[/tex]

Actual area of steel sheet used = 87.12 + 7.26

                                                     = 94.38 [tex]m^{2}[/tex]

Thus, 94.38 [tex]m^{2}[/tex] of steel was used in making the tank.

Answer:

1 cup of milk = 3cups of brown sugar

Answer:

It's 3

Step-by-step explanation:

Because...

When we see the table we can find that it is given 2×3=6, 6×3=18, .... and so on so if we multiply 3 with 1 cup of milk then

3×1=3

So from this the answer is 3

Answer:

2650

Step-by-step explanation:

Ok so,

3000-(3.5(100))

3.5 multiplied by 100 is 350, (move the decimal place 2 times to the right)

so it would be:

3000-350

Simply subtract.

3000-350= 2650

Answer: 2650

Answer:

Step-by-step explanation:

so first what you want to do is split the shape in to

Draw a line down where the 2 is.

you should have a rectangle and a triangle

then you find the area of the rectangle

Rectangle:

5 x 2 = 10m^2

After than you try to find the triangles area

the bottom of the triangle is 9m but since to split it in 2 you will now have 7m

multiple 5 times 7 and you will receive 35 then you divide that by 2 and you will have 17.5m^2

Add your two areas together and you will get 27.5m^2
