On Sunday Sheldon bought 3 and 1/2kg of plant food. He used 1 and 2/3kg on his strawberry plants and used 1/4kg for his tomato p

notsponge [240]

The remaining plant food is: 1 7/12 kg

Step-by-step explanation:

Given

Total Plant food = 3 1/2 kg

Plant food used on Strawberry Plants = 1 2/3 kg

Plant food used on tomato Plants = 1/4 kg

We will first calculate the total food plant used and then subtract the used plant food from the total plant food.

So,

$Total\ Plant\ Food\ used=1\frac{2}{3}+\frac{1}{4}\\=\frac{5}{3}+\frac{1}{4}\\=\frac{20+3}{12}\\=\frac{23}{12}$

Now,

$Left\ Food\ Plant=3\frac{1}{2}-\frac{23}{12}\\=\frac{7}{2}-\frac{23}{12}\\=\frac{42-23}{12}\\=\frac{19}{12}\\=1\frac{7}{12}$

The remaining plant food is: 1 7/12 kg

A school librarian can buy books at a 20% discount from the list price. One month she spent $72 for books. What was the list pri

Nataly_w [17]

Answer:

$\boxed{\sf \ \ YES \ \ }$

Step-by-step explanation:

Hello

let's say that the price of the book was x

the price after a 20% discount is x - 20%*x = x*(1-20%)=x*(1-.20)=0.8*x

and this is $72 so we can write that

0.8*x=72

and then divide by 0.8 both parts

x = 72/0.8=90

So the list price value of the book is $90

and we can verify as 90 - 20%*90 = 90 - 18 = 72

Hope this helps

Look at the middle 7 in the decimal 0.777. How is its value related to the value of the 7 to its left? To the value of the 7 to

masya89 [10]

Answer:

Value of middle 7 = $\frac{1}{10}$ (value of 7 to the left of the middle 7)

Value of middle 7 = $10$ (value of 7 to the right of the middle 7)

Step-by-step explanation:

7 in the middle of number $0.777$ is equal to $\frac{7}{100}$

7 to the left of the middle 7 is equal to $\frac{7}{10}$

So,

$\frac{7}{100}=(\frac{1}{10}) \frac{7}{10}$

That is value of middle 7 = $\frac{1}{10}$ (value of 7 to the left of the middle 7)

Also,

7 to the right of the middle 7 is equal to $\frac{7}{1000}$

So,

$\frac{7}{100}=(10) \frac{7}{1000}$

That is value of middle 7 = $10$ (value of 7 to the right of the middle 7)
