Answer:

5 hours

Step-by-step explanation:

Scott's delivery rate = 10 pizzas per hour

Kenneth's delivery rate = 12 pizzas per hour

Combined delivery rate

= Scotts delivery rate + Kenneth's delivery rate

= 10 + 12

= 22 pizza's per hour (take reciprocal to find the rate in "hours per pizza")

= 1/22 hours per pizza

Given that they both deliver 110 pizzas combined, the will take

= 1/22 hours per pizza x 110 pizzas

= (1/22) x 110

= 5 hours

To reflect over the y axis, the formula is (-x, y). For W, which currently is (-6, -4), the -6 becomes -(-6), which is the same as 6, so the answer is (6, -4).

A company’s board of directors wants to form a committee of 3 of its members. There are 4 members to choose from. How many diffe

Ugo [173]

Answer:

Step-by-step explanation:

There are 4 board members and 3 committee members. You can solve this using combinations:

4C3 = 4!/(3!(4-3)!) = 4!/(3!1!) = 4

You can also solve this by recognizing that since there is one fewer committee spot than there are board members, there will be one possible committee excluding each of the 4 board members.

valina [46]

Answer:

10%

Step-by-step explanation:

The total population of students will be equal to the sum of both those who wore the silly hat and those who didn't hence

Total students= 74+666=740

Number of students who wore silly hat is given as 74 hence when expressed as a percentage of the total students' population we get that

percentage of the students wore a silly hat= $\frac {74\times 100}{740}=10\%$

Therefore, 10% of students wore a silly hat last Tuesday
