Answer
Find out the how far above the water surface is the top of the pipe .
To prove
As given
A pipe that is 3.1 meters long is placed vertically in a pond.
Its lowest point is 1.5 meters under the water surface.
thus
The top of the pipe far above the water surface = 3.1 - 1.5
= 1.6 meter
Therefore the top of the pipe far above the water surface is 1.6 meter .

What is bigger pint or quart
A quart is larger than a pint, as 1 quart equals 2 pints or 4 cups.
In the US customary system of measurement, both pints and quarts are units of volume. Here's the relationship between them:
1 pint = 2 cups
1 quart = 2 pints
To compare the two, let's convert them to a common unit, such as cups:
1 quart = 2 pints = 2 * 2 cups = 4 cups
Since 1 quart equals 4 cups and 1 pint equals 2 cups, it is evident that a quart is larger than a pint. It contains twice the volume of a pint.

A clipboard cost $2.23.It cost $0.58 more than a notebook.Lisa bought two clipboards and one notebook.She paid with a ten dollar bill.How much change does Lisa get?Use a tape diagram to show your thinking.
Lisa gets a change amount of [tex]\fbox {\begin\ \bf \$ 3.89\\\end{minispace}}[/tex] when she pays a ten-dollar bill for two clipboards and a notebook.
Further explanation:
It is given that the cost of a clipboard is [tex]\$\ 2.23[/tex].
Also, it is known that the clipboard costs [tex]\$\text{ }0.58[/tex] more than a notebook so the cost of one notebook is calculated as,
[tex]\fbox {\begin\\\\\begin{aligned}\text{Cost of a notebook}&= 2.23-0.58\\&=1.65\end{aligned}\end{minispace}}[/tex]
Lisa bought two clipboards and one notebook then the total cost for items bought is obtained as the sum of cost of two clipboard and cost of one notebook.
[tex]\fbox {\begin\\\\\begin{aligned}\text{Total cost of two clipboard and one notebook}&= 2.23+2.23+1.65\\&=6.11\end{aligned}\end{minispace}}[/tex]
Lisa paid a ten dollar bill for the purchase of two clipboard and one notebook, so the total change she should get back is obtained as the difference of total cost of two clipboard and one notebook from the total paid price.
The tape diagram for the price paid for two clipboards and one notebook that Lisa bought is as shown in Figure 1 (attached at the end).
Therefore, the change that Lisa gets back is calculated as,
[tex]\boxed{\begin{aligned}\text{Change that Lisa gets}&= 10-6.11\\&=3.89\end{aligned}}[/tex]
Thus, the change amount that Lisa gets after she paid ten dollar for two clipboard and one notebook is [tex]\fbox {\begin\ \bf \$ 3.89\\\end{minispace}}[/tex].

Jayla buys and sells vintage clothing. She bought two blouses for $25.00 each and later sold them for $38.00 each. She bought three skirts for $15.00 each and later sold them for $26.00 each. She bought five pairs of pants for $30.00 each and later sold them for $65.00 each.
Jayla’s expenses for purchasing the items were
Jayla’s revenue from the sale of the items was
Jayla’s total profit was
Answer: Total expenses = $ 225
Total revenue = $479
Total profit = $254
Step-by-step explanation:
Since we have given that
Cost price of each blouse = $25.00
Cost price of two blouses is given by
[tex]25\times 2=\$50[/tex]
Cost price of skirts = $15.00
Cost price of 3 skirts is given by
[tex]3\times 15\\\\=\$45.00[/tex]
Cost price of pairs of pants = $30.00
Cost price of five pairs of pants is given by
[tex]30\times 5\\\\=\$150[/tex]
so, Total expenses for purchasing the items were
Price of 2 blouses +Price of 3 skirts +Price of 5 pairs of pants
[tex]\$50+\$45+\$150\\\\=\$245[/tex]
Selling price of each blouse = $38.00
Selling price of 2 blouses is given by
[tex]38\times 2\\\\=$76[/tex]
Selling price of each skirt = $26.00
Selling price of 3 skirts is given by
[tex]26\times 3\\\\=\$78[/tex]
Selling price of each pair of pants = $ 65.00
Selling price of 5 pairs of pants is given by
[tex]65\times 5\\\\=\$325[/tex]
Total revenue from the sale of the items were
Sale of 2 blouses + Sale of 3 skirts +Sale of 5 pants
[tex]\$76+\$78+\$325\\\\=\$479[/tex]
Total profit was
Total Revenue - Total Expenses
[tex]\$479-\$245\\\\=\$234[/tex]
What is the answer to 43.42 divided 2.6. Need the steps to it
Value of 43.42 divided by 2.6 is:
16.7
Step-by-step explanation:We have to find the value of:

Using the porpotions: WHIP= (Walks+Hits) divide by Innings Pitched. The pitcher wants to lower his WHIP from 1.53 to 1.3. How many more innings would he have to pitch without any walks or hits? Is this a reasonable goal? Explain your reasoning.
There were 85 innings last question and 130 walks + hits which gave a whip score of 1.53 if WHIP= (Walks+Hits).
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Using the portions: WHIP= (Walks+Hits) divide by Innings Pitched. The pitcher wants to lower his WHIP from 1.53 to 1.3.
From the question:
130 / (85 + x) = 1.3
After solving:
19.5 = 1.3x
x = 15
To achieve a target of 1.3 whip score, he would need to pitch 15 more innings without issuing any walks or hits.
Thus, there were 85 innings last question and 130 walks + hits which gave a whip score of 1.53 if WHIP= (Walks+Hits).
