every week Mr. Kirkson uses 3/16 gallon of water to water every 1/3 square foot of his garden. How many gallons of water dose Mr. Kirkson use per square foot to water his garden each week
Answer
Find out the how many gallons of water dose Mr. Kirkson use per square foot to water his garden each week .
To prove
As given
[tex]Every\ week\ Mr. Kirkson\ uses\ \frac{3}{16} gallon\ of\ water\ to\ water\ every\ \frac{1}{3}\ square foot\ of\ his\ garden.[/tex]
[tex]\frac{3}{16}\ gallon= \frac{1}{3}\ square\ foot[/tex]
Now find out for water uses per square foot to water his garden each week .
[tex]1 square foot = \frac{\frac{3}{16}} {\frac{1}{3}}[/tex]
[tex]1 square foot = \frac{3\times 3}{16\times 1}[tex]
[tex]1 square foot = \frac{9}{16}gallon[tex]
1 square foot = 0.5625 gallons
Therefore for Mr. Kirkson use per square foot to water his garden each week is 0.5625 gallons.
Mr. Kirkson will use 9/16 gallons of water for 1 square foot.
What is proportion?The correct relationship between the size of different parts of the same thing, or between one thing and another.
Given that, Mr. Kirkson uses 3/16 gallon of water to water every 1/3 square foot of his garden.
3/16 for 1/3
3*3/16 for 1
9/16 for 1
Hence, Mr. Kirkson will use 9/16 gallons of water for 1 square foot.

Blueberries are on sale for $2.80 per pint. The regular price is $3.50 per pint.
What is the percent of decrease?
Select from the drop-down menu to correctly complete the statement.
Answer: The percent of decrease= 20 %.
Step-by-step explanation:
Regular price of blueberries= $3.50per pint
Current selling price=$2.80 per pint
Clearly, there is decrease in price as 'Current selling price' < 'Regular price'
Now, Decrease in price=Regular price-Current selling price
[tex]=\$3.50-\$2.80=\$0.70[/tex]
We know that Decrease percentage =[tex]\frac{\text{Decreased price}}{\text{Regular price}}\times100[/tex]
[tex]=\frac{0.70}{3.50}\times100\\=\frac{7}{35}\times100\\=\frac{1}{5}\times100\\=20\%[/tex]
Therefore, the percent of decrease= 20 %.

Fiona eats 75 grams of trail mix. How many calories does she eat? If 50 trail mix= 150
Final answer:
To find out how many calories are in 75 grams of trail mix when 50 grams contain 150 calories, set up a proportion and solve for x. The calculation shows that 75 grams of trail mix contains 225 calories.
Explanation:
If 50 grams of trail mix contains 150 calories, to find out how many calories are in 75 grams of trail mix, we need to set up a proportion since the relationship between the weight of the trail mix and the calories it contains is a direct one. This means that if the weight goes up, the calories will also go up by the same rate.
To calculate the calories in 75 grams of trail mix, we use the following steps:
Understand the given information: 50 grams = 150 calories.Set up a proportion to find out how many calories are in 75 grams:$105 skateboard; 7 1/2% tax

What is 62.5% as a fraction in simplest form
Answer:
5/8
Step-by-step explanation:
The required simplest form of 62.5% is 5/8.
Given that 62.5%.
To express a% as a fraction in simplest form, we divide a% by 100 gives,
a% = a/ 100
For example, if a = 75%, gives:
75% = 75/ 100
Simplifying the fraction:
75 / 100
To further simplify, divide both the numerator and denominator by their greatest common divisor (GCD), which is 25:
75 ÷ 25 / 100 ÷ 25
This gives:
3/4
Thus, 75% as a fraction in simplest form is 3/4.
Consider the example of 62.5%.
To express 62.5% as a fraction, divide 62.5% by 100:
62.5% / 100
Simplifying the fraction:
62.5 / 100
To further simplify, divide both the numerator and denominator by their greatest common divisor (GCD), which is 12.5:
62.5 ÷ 12.5 / 100 ÷ 12.5
This gives:
5/8
Therefore, 62.5% as a fraction in simplest form is 5/8.

Last week, Chen bought 8 1/2 gallons of gas at $2.30 per gallon. This week, he bought 4 3/10 gallons of gas at $2.70 per gallon.
What was his total cost?
The total cost of the gallons of gas will be $31.16
Since Chen bought 8 1/2 gallons of gas at $2.30 per gallon, the cost will be:
= 8 1/2 × $2.30
= 8.5 × $2.30
= $19.55
Since he also bought 4 3/10 gallons of gas at $2.70 per gallon, the cost will be:
= 4 3/10 × $2.70
= 4.3 × $2.70
= $11.61
Therefore, the total cost will be the addition of both values gotten and this will be:
= $19.55 + $11.61
= $31.16
Therefore, the total cost is $31.16

Dreanne uploads 292 pictures to her online album.Her online album shows 12 pictures on each page.How many pages does she scroll through to see all 292 pictures?What does the remainder represent
Dreanne needs to scroll through 25 pages to see all her 292 pictures. She scrolls through 24 full pages, and the 25th page has the remaining 4 pictures.
Explanation:To find out how many pages Dreanne has to scroll through to see all 292 pictures in her online album, we need to divide the total number of pictures by the number of pictures per page. We know there are 292 pictures and each page shows 12 pictures.
Dividing 292 by 12, we get:
292 ÷ 12 = 24 R 4
This means Dreanne will have to scroll through 24 full pages of pictures. However, there's a remainder of 4, which means there will be an additional page with only 4 pictures on it. In total, Dreanne will scroll through 25 pages. The remainder represents the number of pictures on the last, non-full page.
