Dillon peeled 40 pounds of potatoes. How many ounces of potatoes did Dillon peel?
Answer:
640
Step-by-step explanation:
40 pounds = 640 ounces
The ounces of potatoes that Dillon peeled is 640 ounces.
What is Unit Conversion?Unit conversion is defined as expressing the same quantity by different measurement units.
For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.
Given that,
Amount of potatoes that Dillon peeled = 40 pounds
We have to convert the same amount of potatoes in to the measurement unit of ounces.
We have to convert the unit.
We have the measurement unit that,
1 pound = 16 ounces
40 pounds = 40 × 16 = 640 ounces
Hence 640 ounces of potatoes did Dillon peel.

if you stop at random in front of an animal exhibit,What is the probability that you will be looking at monkeys? I put the table chart below
Answer:
1/10
step-by-step explanation:
----------------------------------
| animals | percent of animals |
----------------------------------
| goats | 16% |
----------------------------------
| camels | 4% |
----------------------------------
| giraffes | 6% |
----------------------------------
| llamas | 6% |
----------------------------------
| deer | 1% |
----------------------------------
| monkeys | 10% |
----------------------------------
| birds | 27% |
----------------------------------
| reptiles | 14% |
----------------------------------
| bears | 16% |
----------------------------------
( sorry if the table above isnt 100% right or straight ^ )
first you add up all the percents of how much animals are in this exhibit
16 + 4 + 6 + 6 + 1 + 10 + 27 + 14 + 16
= 100 %
then since we are looking for the probability of stopping in front of the monkeys, we take that 100 we got earlier and get the 10% of monkeys from our table
10/100
but since there isnt a 10/100 on the answers we look for something that equals to 10/100 and 1/10 does since you can just times both the 1 and 10 to equal the 10 and 100 you were looking for
1/10
making 1/10 your answer!

Veronica took her friend out for a birthday dinner. She purchased an appetizer
for $7.95, two entrées for $12.95 and $15.95, two drinks for $3.50 each, and two
desserts for $6.95 each. She had a 25% off coupon. A sales-tax rate of 9.25% was
then added. How much was the meal? If Veronica left a 20% tip, how much did
she leave for the tip? *
Answer:
Veronica left a tip of $6.87
Step-by-step explanation:
3.50×2= 7
6.95×2= 13.9
7.95+12.95+15.95+7+13.9 = 41.8
0.25×41.8= 10.45
41.8-10.45= 31.35
0.0925×31.35 = 3
31.35+3 = 34.35
0.20×34.35 = 6.87

C : 4√2
Step-by-step explanation:
An triangle has two sides of equal right angles
We call the perpendicular side a, the isosceles triangle FGD at G
According to the Pythagorean Theorem
FH = √FG² + GH² = √a²+ a² => a√2 = 8
⇒a = 4√2
Edward and Jacob are competing for the same job cutting firewood. While interviewing,
Edward reported that he can cut five cords of firewood in eight hours. (A cord is the
official measurement for firewood. It is actually a measurement for volume.) Jacob,
trying to sound more impressive, says he can cut 162 cords in 100 hours. Who would you
hire as the better firewood cutter? Why? Explain completely.
Answer:
I would hire Jacob.
Step-by-step explanation:
Jacob is trying to sound more impressive knowing that Edward has more cords per hour. The writers of the question wouldn't say "trying to SOUND more impressive" if Jacob actually WAS more impressive. But maybe that's what they want you to think. If you take the 5 cords of Edward and divide it by the eight hours that it takes him to do you will notice he has an average of 0.625 cords per hour. And if you take a look at Jacob's average you immediately notice that he has an average of ABOVE 1. Jacob has an average of 1.62 cords per hour. Therefor Jacob is more efficient in this category of work. That's why I would hire Jacob.

A farmer sells 9.4 kilograms of pears and apples at the farmer's market. 2 5 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Answer: 6.9 kg
Step-by-step explanation:
Given
The combined weight of apple and pears is 9.4 kg
If pears weigh 2.5 kg
The weight of apples is the subtraction of pears weight from the total
[tex]\Rightarrow 9.4-2.5=6.9\ kg[/tex]
Thus, the farmer sells 6.9 kg of apples

Clare said that 4/3 divided by 5/2 is 10/3 She reasoned: 4/3 x 5 equals 20/3 and 20/3 divided by 2 is 10/3 Explain why Clare's answer and reasoning are incorrect. Find the correct quotient.
Answer: See explanation
Step-by-step explanation:
4/3 ÷ 5/2
To solve this further, the minus sign changes to multiplication and the inverse of 5/2 is written. This will be:
= 4/3 ÷ 5/2
= 4/3 × 2/5
= 8/15
Claire's reasoning is wrong as she didn't multiply by the inverse of the number.
8a-6=34 can some one help me with this problem it will be really helpful
