A scientist observes that a zebra ran 54 yards in 135 seconds. The zebra ran at a rate of _ feet per minute

Answers

Answer 1

Answer: First convert yards to feet, there are 3 feet in a yard so it's just 54x3 which is 162 ft, the convert seconds to minutes so the zebra ran for 135 seconds with 60 seconds in a minute meaning it ran for 135/60 which is 2.25 minutes, then just divide the feet over the minutes to solve ft/min so 162/2.25 gives you 72, which means the answer is just 72ft/minute

What are 4 equations that equal 16

Answers

The 4 equations that equals 16 will be $4*4=16\n$ , $12+4=16$ , $18-2=16$ and $(80)/(5) =16$ .

In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equal sign "=".

Equations often contain algebra. Algebra is used in Math when you do not know the exact number in a calculation.

But, in given question, there is no variable in the statement so we use only constant to make equation which is equal to 4.

Now the equation will be,

$4*4=16\n$
$12+4=16$
$18-2=16$
$(80)/(5) =16$

a bottle contains 20 fluid ounces of lotion and sells for $5.80. The 20-fluid-ounce bottle contains 125% of the lotion in the next smallest size, which sells for $5.12. Which is the better buy? Explain

Answers

here is a way to solve wihtout knowning the volume of the smaller bottle (which is 16oz, btw)

if 5.8 is 125% of the volume of the other one
find what it would cost for 100%
5.8=125% of volume
1.16=25% of volume
4.64

that contains the sameamount as theother one

4.64<5.12

the 20 oz bottle is the better buy

don't believe me?

20=125% of other
4=25% of other
16=100% of other

let's find the cost per ounce of lotion
5.8/20?5.12/16 where ? represents a relation symbol (=,> <)
0.29?0.32
0.29<0.32

20 oz bottle is the better buy

the 20 fluid ounce because you get more for .78 cents more
