Solve the proportion 40/z+1 = 15/6

Mathematics
1 answer:
vovangra [49]3 years ago
7 0

Answer:

<h2>z = 15</h2>

Step-by-step explanation:

\frac{40}{z + 1}  =  \frac{15}{6}  \\

<u>Cross multiply </u>

That's

15(z + 1) = 40(6) \\ 15z + 15 = 240

<u>Send 15 to the right side of the equation</u>

15z = 240 - 15 \\ 15z = 225

Divide both sides by 15

\frac{15z}{15}  =  \frac{225}{15}  \\

We have the final answer as

<h3>z = 15</h3>

Hope this helps you

How do you write 5y&lt;3 without exponents?
satela [25.4K]

Answer:

When an exponent is 1, the base remains the same. a 1 = a . When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Shown below is an example of an argument for a 0 =1 using one of the previously mentioned exponent laws.

Find the equation of the line passing through the points A (2,1) B (7,9)
Bezzdna [24]
m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{9 - 1}{7 - 2} = \frac{8}{5} = 1\frac{3}{5}
              y - y₁ = m(x - x₁)
               y - 1 = 1³/₅(x - 2) Point - Slope Form
               y - 1 = 1³/₅(x) - 1³/₅(2)
               y - 1 = 1³/₅x - 3¹/₅
                 + 1           + 1
                    y = 1³/₅x - 2¹/₅ Slope - Intercept Form
         -1³/₅x - y = 1³/₅x - 1³/₅x - 2¹/₅
          -1³/₅x - y = -2¹/₅
     -1(-1³/₅x - y) = -1(-2¹/₅)
-1(-1³/₅x) + 1(y) = 2¹/₅
           1³/₅x - y = 2¹/₅ Standard Form
         1³/₅(0) - y = 2¹/₅
                0 - y = 2¹/₅
                    -y = 2¹/₅
                    -1    -1
                     y = -2¹/₅ Y - Intercept
               (x, y) = (0, -2¹/₅)

Help Please<br><br><br> thats my image
Alenkasestr [34]

Answer:

\frac{5}{6}

Step-by-step explanation:

The total number of squares is 36, and only 6 of them are shaded therefore, the remaining 30 are not shaded. The probability that a randomly selected square is not shaded would therefore be:

\frac{30}{36}  =  \frac{10}{12}  \\ =   \frac{5}{6}

miskamm [114]

Answer:

        1  

= -----------

   6(x + 7)

Step-by-step explanation:

3x - 21      x^2 - 49

----------- ÷ -------------

18x - 18        x - 1

3x - 21          x - 1

----------- ×  -------------

18x - 18       x^2 - 49

Factor the top left:

3x - 21  = 3(x - 7)

Factor the bottom left:

18x - 18 = 18(x - 1)

Factor the new bottom right:

x^2 - 49 = (x + 7)(x - 7)

Multiply and simplify the faction:

3(x - 7)            x - 1

----------- ×  -----------------

18(x - 1)       (x + 7)(x - 7)

        1  

= -------------

   6(x + 7)
