Answer 1

Answer: 13. There are 3 feet in a yard. You divide 34 by 3 and get 11 with one left over. So it should be 11 yards and 1 foot.
14. 16 oz. = 1 lb. If you multiply 16 (oz) x 8 (lbs.) you get 128 ounces.

Answers

assuming number cube has 6 sides

probablity is (desiredoutcomes)/(total possible ouctomes)

since it is 450 times
total possible outcomes=450

experimiental probablity is the one actaully obtained by doing it
theoretical is the predicted amount

so theoretical probablity of rolling a 3 is 1 number out of 6 or 1/6 or 75 times out o 450 times

experimiental is the actaull one so67 out of 450 or 67/450

theoretical is 1/6 or 75/450
experimental is 67/450

A store has apples on sale for $3.00 for 2 pounds. How many pounds of apples can you buy for $9? If an apple is approximately 5 ounces, how many apples can you buy for $9? Explain your reasoning.

Answers

we know that

A store has apples on sale for $ $3.00$ for $2$ pounds

Part a) How many pounds of apples can you buy for $ $9$ ?

by using proportion

$(3)/(2)(usd)/(pound) =(9)/(x) (usd)/(pound) \n \n 3x=9*2\n \n x=(18)/(3) \n \n x=6 pounds$

therefore

the answer Part a) is

$6 pounds$

Part b) If an apple is approximately $5$ ounces, how many apples can you buy for $ $9$ ?

we know that

$1 pound=16 ounces$

step 1

convert ounces to pounds

$1apple=(5)/(16)pounds$

by using proportion

$(1)/((5)/(16))\ (apples)/(pounds) =(x)/(6) (apples)/(pounds)\n \n x(5)/(16) =6\n \n x=(16*6)/(5) \n \n x=19.2 apples$

therefore

the answer part b) is

about $19 apples$

Since 2 pounds is $3 and you have $9, you would do:

$(3)/(2) = (9)/(x)$ , x= # of pounds of apples

You do cross multiplication to get:

$3x=18$

x=6

1 lb= 16 oz

So $6*16=96$ to get the number of ounces you can buy for $9.

Then divide 96 by 5, so that is ABOUT 19 APPLES.

Dave can paint the office by himself in 4 hours. Working with an associate, he can paint theoffice in 3 hours. How long would it take his associate to do it working alone?

Answers

Answer:

It would take 12 hours for his associate to do the complete work alone.

Step-by-step explanation:

Let 'x' be the hours taken by his associate working alone.

Given:

Time to paint the office by Dave is 4 hours.

Time to paint the office together is 3 hours.

Therefore, the part of work completed by Dave alone in 1 hour is $(1)/(4)$

Part of work completed by an associate in 1 hour is $(1)/(x)$

Now part of work completed by both in 1 hour is $(1)/(3)$

Therefore,

$(1)/(4)+(1)/(x)=(1)/(3)\n\n(1)/(x)=(1)/(3)-(1)/(4)\n\n(1)/(x)=(4-3)/(12)\n\n(1)/(x)=(1)/(12)\n\nx=12\ h$

Therefore, it would take 12 hours for his associate to do the complete work alone.

A grocery store only sells eggs by the dozen.There are 12 eggs in one dozen eggs.If there are 624 eggs in stock how many dozens of eggs are there

Answers

work:

624 divided by 12 equals 52

answer:

52 dozens

Final answer:

Given a stock of 624 eggs and knowing 1 dozen equals 12 eggs, there are 52 dozen eggs in the store.

Explanation:

The subject of this question pertains to Mathematics, specifically a real world application of division. In the given query, a grocery store only sells eggs by the dozen, meaning twelve eggs. The store has in stock, 624 eggs. The task is therefore to determine how many dozens make up this total number of eggs available.

To find the answer, we divide the total number of eggs by the number of eggs in one dozen. That is 624 (total number of eggs) divided by 12 (number of eggs in a dozen). This equals 52 dozens. Thus, the grocery store has 52 dozens of eggs in stock.
