Hours = 34 Income per hour = 12.5$ Service calls = 6 Income per call = 4 Therefore, total income = (time of working * income per hour) + (service calls * income per call) = (34*12.5) + (6*4) = 425+24 = 449

It is 2 miles from Ellie’s house to school, 1 mile = 5280 feet. How many feet is it from Ellie’s house to school ?
Lana71 [14]
This is a conversion problem. We know that 1 mile is 5280 feet, right? Since Ellie lives 2 miles, and two is double of 1, we just take 5280 and multiply that by two (or add it twice) to find how many feet is between Ellie's house and school. 5280 x 2 = 10560 (you get the same answer if you add 5280 twice). Therefore, 10560 feet lies between Ellie's house and school.

X^2/9+2y/7 help me solve
vfiekz [6]

So firstly, we have to find the LCD, or lowest common denominator, of 9 and 7. To do this, list the multiples of 9 and 7 and the lowest multiple they share is going to be your LCD. In this case, the LCD of 9 and 7 is 63. Multiply x^2/9 by 7/7 and 2y/7 by 9/9:

\frac{x^2}{9}\times \frac{7}{7}=\frac{7x^2}{63}\\\\\frac{2y}{7}\times \frac{9}{9}=\frac{18y}{63}\\\\\frac{7x^2}{63}+\frac{18y}{63}

Next, add the numerators together, and your answer will be: \frac{7x^2}{63}+\frac{18y}{63}=\frac{7x^2+18y}{63}

The intersection between the complement of set A and the complement of set B is 7.

<h3>What is a Venn diagram?</h3>

A Venn diagram is a visual representation that shows mathematical sets as circular curves inside of a rectangle (known as the universal set).

From the Venn diagram, we are to find the intersection between the complement of set A and the complement of set B.

\mathbf{A^c = \{ 7,6,11 \}} \\ \\ \\ \mathbf{B^c = \{7,9,13 \}}

Therefore, the intersection between the two sets is the set of elements that exists in both of them. Therefore, we have:

\mathbf{n(A^c \cap B^c) = \{7\}}
