Answer:

x = 62.1

Step-by-step explanation:

Note the equal sign in this equation, what you do to one side, you do to the other. Isolate the variable, x, by dividing 10 from both sides of the equation:

[tex]621 = 10x\\\\\frac{621}{10} = \frac{10x}{10} \\\\x = \frac{621}{10} \\x = 62.1[/tex]

Hi there!

If the nickels and dimes ratioe are both 2:6, then the quarter is also 2:6.

The total of of all together is also 6:6 and 6:6 is also 120 coins.

120 divide by 3 different kinds of coins are 40.

This means that there are 40 of 1 coin out of 3 different kinds of coins. What I really mean is that each coins all have 40 each...

Therefore, the ratios of nickels to dimes and to quarters are 40:40:40...

Answer:

2 9/14

Step-by-step explanation:

first we must make 1/6 and 3/7 have common demoniaters! (or however u spell it)

1/6 x 7/7 = 7/42

3/7 x 6/6 = 18/42

7/42 + 18/42 = 25/42

2/7 x 6/6 = 12/42

25/42 + 12/42 = 37/42

37/42 + 7/42 = 44/42

44/42 + 18/42 = 62/42

62/42 + 12/42 = 74/42

5/7 x 6/6 = 30/42

74/42 + 30/42 = 104/42

104/42+7/42 = 111/42

111/42 = 2 9/14

Answer:

2 miles.

Step-by-step explanation:

In this case, we would multiply the numerator by 3 since we know that it takes him 10 minutes to run 2/3 of a mile. So, 2x3 = 6. Which gives us 6/3. Simplified that would be 2 miles. Hope this helps!

The number of campers who voted for hotdogs is 40 campers

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of campers who voted for hot dogs = 5 campers

Let the number of campers who voted for sphagetti = 4 campers

Now , the total campers = 5 + 4

                                        = 9 campers

5 out of 9 campers vote for hot dogs

So ,

The total number of campers = 72 campers

The equation will be ,

The total number of campers who voted for hotdogs =
( number of campers who voted for hot dogs / the total campers ) x 72

The total number of campers who voted for hotdogs = ( 5 / 9 ) x 72

                                                                                        = 5 x 8

The total number of campers who voted for hotdogs = 40 campers

Hence , The number of campers who voted for hotdogs is 40 campers

[tex]\sf {tan~K} = \sf{{\dfrac{opposite~side}{adjacent~side}}} =\sf{{\dfrac{24}{51}}} [/tex]

None of the answers are correct

Answer:

Step-by-step explanation:

Picture 1

In right triangle ABC,

Side AB is the opposite side of angle C.

Picture 2

In triangle MKL,

tan(∠M) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

             = [tex]\frac{KL}{KM}[/tex]

             = [tex]\frac{15}{8}[/tex]

Option (1) is the answer.

Picture 3

In ΔXYZ,

sin(∠Z) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

            = [tex]\frac{XY}{XZ}[/tex]

For the length of XY we will apply Pythagoras theorem in ΔXYZ,

XZ² = XY² + YZ²

XY² = XZ² - YZ²

      = (40)² - (32)²

XY = √576

     = 24

sin(Z) = [tex]\frac{24}{40}[/tex]

sin(Z) = [tex]\frac{3}{5}[/tex]

Picture 4

In right triangle DEF,

Cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

           = [tex]\frac{EF}{DF}[/tex]

           = [tex]\frac{75}{72}[/tex]

           = [tex]\frac{25}{24}[/tex]

Picture 5

In ΔABC,

tan(63°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(63°) = [tex]\frac{BC}{AB}[/tex]

AB = [tex]\frac{BC}{\text{tan}(63)}[/tex]

AB = [tex]\frac{8}{\text{tan}(63)}[/tex]

AB = 4.0762 ≈ 4 m

Option (3) will be the answer.

Answer:

IQR = 10

Step-by-step explanation:

1. Find the median (middle data point.)

2. Find the median of the upper quartile (70 - 80.)

3. Find the median of the lower quartile. (60 - 70.)

4. Subtract the lower quartile from upper quartile.

1. median of the data = 70

2. median of Q2 = 75

3. median of the Q3 = 65

4. 75 - 65 = 10

IQR = 10

Answer:

a) Given that w=81 and k = 0.375 then r = 6

b)  Given that s=27 and k = 224 then w=32

Step-by-step explanation:

Step(i):-

Given that W varies directly as r³

      ⇒ w∝r³

    ⇒   w = kr³

where 'k' is proportionally constant

given that w= 24 and r =4

     ⇒  24 = k (4)³

     ⇒ k = [tex]\frac{24}{64}[/tex]

    ⇒ k = 0.375

Step(ii):-

Given that W varies indirectly as 's'

            w ∝[tex]\frac{1}{s}[/tex]

            W =k [tex]\frac{1}{s}[/tex]

where 'k' is proportionally constant

          28 = k ([tex]\frac{1}{8}[/tex])

        k = 28 × 8 = 224

Step(iii):-

a) Given that w=81 and k = 0.375

     w = kr³

   81 = 0.375 (r)³

   r³ = 216

  r = ∛216 =6

 r =6

b)

 Given that s=27 and k = 224

          W =k [tex]\frac{1}{s}[/tex]

         w = 224 ([tex]\frac{1}{27}[/tex])

        w = 32

Step-by-step explanation:

I would say the area its getting built. imagine wanting to build a house but you can't dig the sewer (if thats the spelling) pipes bc the area you want doesn't have any water or something like that. definitely money. without it, you can't do anything, you can't buy materials or even hire people to help you because you cannot tell me that you can build a house on your own. Another I would say is Labor cause like I said, if you ain't got nobody to help you, you're probably going to take a few years or more. so if you want to build a house in an area where there is a few architects and designers, you're just going to have to suck it up and get what you get.
