A plumber charges a $25 flat rate. If he works for 6 hours, how much does he charge per hour if the total is $67?

Answer:

61

Step-by-step explanation:

b(a + b) + a

First, distribute b to a+b

ba + b^2 + a

Now, substitute values

9(4) + 4(4) + 9

36 + 16 + 9 = 61

The probability that a data value is between 54 and 66 is 81.9%

z score is used to determine by how many standard deviations the raw score is above or below the mean.

The z score is given by:

[tex]z = \frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]

Given that μ = 62, σ = 4

For x = 54:

[tex]z=\frac{54-62}{4}=-2[/tex]

For x = 66:

[tex]z=\frac{66-62}{4}=1[/tex]

P(54 < x < 66) = P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 81.9%

The probability that a data value is between 54 and 66 is 81.9%

The area of the shape is 110 square centimeters

From the diagram, the shape can be subdivided into rectangles of the following dimensions:

So, the area of the shape is the sum of the areas of the three rectangles.

This gives

[tex]Area = 6cm \times 11cm + 5cm \times 6cm + 7cm \times 2cm[/tex]

Evaluate the products

[tex]Area = 66cm^2 + 30cm^2 + 14cm^2[/tex]

Add the terms

[tex]Area = 110cm^2[/tex]

Hence, the area of the shape is 110 square centimeters

Answer:

A)

Step-by-step explanation:

Given expression:

[tex] \boxed{\mathsf{c = 15 + am}}[/tex]

subtracting 15 from both sides, and combining like terms on the RHS

[tex] \implies\mathsf{c - 15 = (15 - 15)+ am}[/tex]

Dividing both sides by a

[tex] \implies\mathsf{ \frac{c - 15}{a} = am \times \frac{1}{a} }[/tex]

a On the RHS gets canceled for being present in both Numerator as well as denominator, and were left with the following equation:

Answer:

3/10

Step-by-step explanation:

0.4 - 0.1 = x

there are two ways I can find the answer to this question.

Option 1

0.4 - 0.1 = 0.3 then turn it into a fraction which would be 3/10

or I can turn both into fraction and subtract them

4/10 - 1/10 = 3/10

Both ways would give you the same answer!

I hope this helps!!

Please tell me if I have made any mistakes I enjoy learning form them:)

The value of 0.4 - 0.3 = 0.1 and the fractional form is 3/10

What is a Fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the equation be A = 0.4 - 0.1

The value of A = 0.4 - 0.1

                         = 0.3

A = 0.3

Multiply by 10 on both sides , we get

10A = 3

Divide by 10 on both sides , we get

A = 3/10

Hence , the fractional form of 0.3 is 3/10
