Answer:

given ,

\bold{ZH = (11x - 29)}

Also ,

\bold{x = 19}

substituting the value of x in the value of ZH , we get

\bold{ZH = 11(19) - 29 }\\\bold{ ZH = 209 - 29 }\\ \bold\blue{ZH = 180}

hope helpful~

Determine whether or not the equation shows a proportional relationship. If it does, identify the unit rate (constant of proport
sergiy2304 [10]

Answer:

y = 25·x shows a proportional relationship

a = 5·x + 5 does not show a proportional relationship

m = 105.25·n shows a proportional relationship

Step-by-step explanation:

An equation that shows a proportional relationship is of the form, y = kx

Where;

k = The constant of proportionality = y/x

Therefore, the equation, y = 25·x shows a proportional relationship

The constant of proportionality = k = y/x = 25

Similarly, the equation m = 105.25·n shows a proportional relationship

The constant of proportionality = k = m/n = 105.25

When the equation shows a proportional relationship, the graph of the equation passes through the origin, therefore, the equation of the form, y = m·x + c, where c = the y-intercept > 0, the equation does not show a proportional relationship

The equation a = 5·x + 5, which is of the form, y = m·x + c, with c = 5 > 0, therefore, does not show a proportional relationship.

Therefore;

y = 25·x shows a proportional relationship

m = 105.25·n shows a proportional relationship

a = 5·x + 5 does not show a proportional relationship.

Chong thinks of a Number adds 10 and then multiplies the number so obtained by 3, and get 42. If the number is n then write an e
eimsori [14]

Answer:

The equation for this is: 3(n+10) = 42

Step-by-step explanation:

We have that the number though is n.

Adds 10:

This means that now we have: n + 10

Multiplies by 3:

This means that now we have: 3(n+10)

Gets 42:

This means that: 3(n+10) = 42

An airline promotion to business travelers is based on the assumption that two-thirds of business travelers use a laptop compute
skad [1K]

Answer:

a

  The null hypothesis is  H_o  :  p =  0.67

   The alternative hypothesis is  H_a : p \ne 0.67

b

 The sample proportion is \^ p  =  0.65

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  546  

      The number of people that use a laptop overnight is  k = 355

    The population proportion is  p =  \frac{2}{3}  =  0.67

   Generally

  The null hypothesis is  H_o  :  p =  0.67

   The alternative hypothesis is  H_a : p \ne 0.67

Gnerally the sample proportion is mathematically represented as

        \^ p  =  \frac{ k}{n}

=>     \^ p  =  \frac{ 355}{546}

=>     \^ p  =  0.65

The length of a rectangular garden is 5x+5
REY [17]

Answer:

4x+14

Step-by-step explanation:

we know that in a rectangle, 2 sides are equal to one another (opposite sides), and the other 2 are equal to each other.

so,

2(5x+5) for the first 2 sides. you'd get 10x+10

2(2-3x) for the other two sides. you'd get -6x+4

add them up, and you'd get 4x+14
