By the Pythagorean Theorem a^2+b^2=c^2 or the sum of the squared sides is equal to the hypotenuse squared.

41^2=9^2+h^2

h^2=41^2-9^2

h^2=1600

Answer:

While 3/4 and 6/8 are equivalent fractions, 3/4 and 6/8 of a pizza could represent different amounts.

Answer: how are you doing this tho

Step-by-step explanation:

The 1/3 of 5/8 as a fraction is 5/24 after applying the arithmetic operation the answer is 5/24.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

1/3 of 5/8 as a fraction

Let x be the fraction:

x = 1/3 of 5/8

Or

x = (1/3)(5/8)

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

After multiplication:

x = 5/24

Thus, the 1/3 of 5/8 as a fraction is 5/24 after applying the arithmetic operation the answer is 5/24.

Answer:

x = 54

Step-by-step explanation:

Since both triangles are similar, therefore,

[tex] \frac{UV}{PQ} = \frac{VW}{QR} [/tex]

[tex] \frac{77}{66} = \frac{63}{x} [/tex]

[tex] \frac{7}{6} = \frac{63}{x} [/tex]

Cross multiply

[tex] 7*x = 63*6 [/tex]

[tex] 7x = 378 [/tex]

Divide both sides by 7

x = 54

Answer:

Mean=76

Median=72.5

Step-by-step explanation:

Mean= 70+71+72+73+74+96

                         456/6=76

Median = 70,71,72,73,74,96

               72+73=145/2=72.5

Mean= 76

Median= 72.5

The first step is to rearrange the numbers

70, 71, 72, 73, 74, 96

1. mean= sum of terms/number of terms

= 70+71+72+73+74+96/6

= 456/6

= 76

2. Median can be described as the middle number, the median can be calculated as follows

= 72+73/2

= 145/2

= 72.5

Hence the mean is 76 and the median is 72.5

Answer:

The side of the hypotenuse is 12.233 centimeters.

Step-by-step explanation:

The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:

[tex]\cos 56^{\circ} = \frac{7.4\,cm}{x}[/tex] (1)

Where [tex]x[/tex] is the length of the hypotenuse, measured in centimeters.

Then, we clear the variable within (1):

[tex]x = \frac{7.4\,cm}{\cos 56^{\circ}}[/tex]

[tex]x = 13.233\,cm[/tex]

The side of the hypotenuse is 12.233 centimeters.

(f o g)(x) = 4x^2 - 8

Step-by-step explanation:

(f o g)(x) = f(g(x))

f(x) = x^2 - 8

g(x) = 2x

f(g(x))

f(2x) = (2x)^2 - 8

       = 4x^2 - 8

(f o g)(x) = 4x^2 - 8

Answer:

Step-by-step explanation:

You haven't stated a problem. Do you want to add the fractions together? Subtract them?

Least common multiple of 8 and 5 is 40.

1/8 = 5/40

9/5 = 72/40

1/8 + 9/5 = 5/40 + 72/40 = 77/40 = 1 37/40

Answer:

4x+6

Step-by-step explanation:

The quotient of a number and 4 translates to 4x because, "a number" in the expression is x, and it is being multiplied by 4, so you get 4x. six more than would mean adding 6. So the answer would be 4x+6. Thank you! Good Luck!

Answer:

(x - 10, y - 13)

Step-by-step explanation:

We have two shapes on a graph and the question is asking for the translation of rhombus QRST to rhombus Q'R'S'T.

Looking at the graph we can see that not only does the rhombus move backwards, but also downward, this indicates that our answers will be in a subtracting symbol.

So all we have to do is count the amount of spaces rhombus QRST went to get to rhombus Q'R'S'T

Answer:

Number of dogs (x) | Amount charged to walk a dog (y)

1 | 20

2 | 40

3 | 60

4 | 80

5 | 100

6 | 120

7 | 140

8 | 160

Step-by-step explanation:

Charge for walking a dog = $20 per dog

Number of dogs = x

Amount charged to walk a dog in a day = y

Unit rate = 20

Equation to represent this is: y = 20x

Let's use this to form a table for walking 1 to 8 dogs:

For 1 dog (x):

y = 20(1) = $20

For 2 dogs (x):

y = 20(2) = $40

For 3 dogs(x):

y = 20(3) = $60

For 4 dogs:

y = 20(4) = $80

And so on till we get to tl8 dogs.

This, we should have the following table:

Number of dogs (x) | Amount charged to walk a dog (y)

1 | 20

2 | 40

3 | 60

4 | 80

5 | 100

6 | 120

7 | 140

8 | 160

Answer:

t - b >= e

Step-by-step explanation:

There are few actual necessities that a person actually needs in order to survive, everything else is actually a want and not a necessity. Such necessities include food, water, and rent. These can be represented as

Budget = b

We can use them in the following equality. While e would be representing the entertainment and t represents the total money he has.

t - b >= e

You can now plug in the actual values for t and b to find out how much you would have left for entertainment.

The required base of the isosceles triangle is given as 38 feet.

A triangle with two sides and two congruent angles is called an isosceles triangle.

here,

For a given isosceles triangle,
side/base = 2 / 7
side = 2/7 base = 7 /2 sides

According to the question,
The perimeter of the triangle is 304 feet,
2 side + base = 304
2 [7/2 base] + base = 304
8 base = 304
base= 304 / 8
base = 38 feet

Answer:

[tex]\boxed{\textsf{ The value of x is \textbf{ 8 + 6}$\sqrt{3 }$.}}[/tex]

Step-by-step explanation:

Here we are given a equation which we need today simplify and solve for x .The given equation to us is :-

[tex]\sf\implies \dfrac{1}{x {}^{2} - 3 } = \dfrac{ \sqrt{3} }{x + \sqrt{3} } - \dfrac{2}{ \sqrt{3} - x } [/tex]

Let's simplify the equation :-

[tex]\sf\implies \dfrac{1}{x {}^{2} - 3 } = \dfrac{ \sqrt{3} }{x + \sqrt{3} } - \dfrac{2}{ \sqrt{3} - x } \\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3}{x+\sqrt3}-\dfrac{2}{-(x-\sqrt3)}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3}{x+\sqrt3}+\dfrac{2}{x-\sqrt3}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3(x-\sqrt3)+2(x+\sqrt3)}{(x+\sqrt3)(x-\sqrt3)}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3x-3+2x+2\sqrt3}{x^2-3}\\\\\sf\implies 1=\sqrt3x-3+2x+2\sqrt3 \\\\\sf\implies \sqrt3x+2x = 4-2\sqrt3\\\\\sf\implies x(\sqrt3 +2)=4-2\sqrt3\\\\\sf\implies x =\dfrac{4-2\sqrt3}{\sqrt3+2}\\\\\sf\implies x =\dfrac{ (4-2\sqrt3)(\sqrt3-2)}{(\sqrt3+2)(\sqrt3-2)}\\\\\sf\implies x =\dfrac{-8-6\sqrt{3}}{3-4}\\\\\sf\implies \boxed{\pink{\sf x =8+6\sqrt3}}[/tex]

Answer:

x = -2y - 9

Step-by-step explanation:

First isolate the variable by putting the x on a side by itself.

-4x=36+8y (8y becomes positive when it changes sides)

Then divide the entire equation by -4 to make the x stand alone.

x = -9 -2y

Some teachers prefer the variables at the beginning of the equations so it could also read

x = -2y - 9

Hello there!

Question:-

[tex]-4x-8y=36[/tex]

We need to find the value of x.

Solution:-

[tex]\sf \longmapsto-4x-8y=36[/tex]

Firstly, Add 8y to both sides :-

[tex]\sf \longmapsto \: - 4x - 8y+8y=36+8y[/tex]

On Simplification:-

As (-) and (+) equals to (-),It Will be 8y-8y.Answer would be 0.

[tex]\sf \longmapsto \: - 4x - 0 = 36 + 8y[/tex]

[tex]\sf \longmapsto \: - 4x = 8y + 36[/tex]

Then, Divide both sides by -4:-

[tex]\sf \longmapsto \: \dfrac{4x}{ - 4} = \dfrac{8y + 36}{ - 4} [/tex]

On Simplification:-

[tex]\sf \longmapsto \: x = - 2y - 9[/tex]

______________________________________

Henceforth the value of x is :-

[tex] \boxed{\tt \: x = - 2y - 9}[/tex]
