namely how many times does 1/10 go into 3/4?

\bf \cfrac{3}{4}\div \cfrac{1}{10}\implies \cfrac{3}{4}\cdot \cfrac{10}{1}\implies \cfrac{3}{1}\cdot \cfrac{10}{4}\implies \cfrac{3}{1}\cdot \cfrac{5}{2}\implies \cfrac{15}{2}\implies 7\frac{1}{2}

Answer:

7 1/2 weeks

Step-by-step explanation:

To determine how many weeks her food will last, we take the amount of food and divide by how much she feeds her cats.

3/4 bag ÷ 1/10 bag per week

Copy dot flip

3/4 * 10/1

30/4

15/2

7 1/2 weeks

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)

If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X.
