An antelope can run a speed of 61 miles per hour. What is this speed in yards per second? Round to the nearest hundredth
DochEvi [55]

Answer:

= 29.82 yards/second

Step-by-step explanation:

The speed is given in the problem.  We just need to convert its units.  The multiplicative identity (that is, 1) may be used to change the units without changing the value.  (note:  do you know what the additive identity is?)

     61 miles per hour

    (61 miles) / (1 hour)

   (61 miles)/(1 hour)*1

   ((61 miles)/(1 hour))*((5280 feet)/(1 mile))

   ((61 miles)/(1 hour))*((5280 feet)/(1 mile))*((1 yard)/(3 feet))*((1 hour)/(60 minutes))*((1 minute)/(60 seconds))

      note:  miles, feet, hours, minutes cancel out; leaving yards per second

    (61/1)*(5280/1)*(1/3)*(1/60)*(1/60)   yards/second          (note: I write that way to paste into Excel)

What is the product of 16x48?
Elis [28]
768 because 6x8 = 48 the 8 drop Down to the answer and the 4 on top of 1 and multiply 1x8= 8+1 =9 so the 9 drop down to the answer. Now that is fake because you need to multiply 4x6 and 4x1 so 4x6 is 24 below the 8 add a 0 and go 1 move to the left and put 4 and 2 on top of 1 now 4x1 is 4+1 is 5 and put 5 on the left of 4 and the final step is add 98+540=768 so 768 is your real answer.

Employees at Driscoll's Electronics as a base salary plus a 20% Commission on their total sales for the year. Suppose. The base
never [62]

Answer:

Step-by-step explanation:

Let x represent the total sales made in a year.

Employees at Driscoll's Electronics as a base salary plus a 20% Commission on their total sales for the year. If the base salary is $40,000, it means that if the employee makes a total sales of $x in a year, the total equation to represent earnings would be

0.2x + 40000

b) if Stewart wants to make $65,000 this year, it means that

0.2x + 40000 = 65000

0.2x = 65000 - 40000

0.2x = 25000

x = 25000/0.2

x = 125000

c) 52,000 + 0.3s = 82,000

The base salary is $52000

The percentage of commission from sales is 30%
