8. james had a 3-quart water bottle. Eileen bought 1-gallon jug. whose container holds more cups? ------ How many more? ------- cups
please, please help, will give brainliest if correct. by the way this is 4th grade math.
Answer:
6. (a) No Mr Lee did not order the correct amount of milk.
(b)Mr Lee should have ordered for 48 pints of milk.
7. 156 pints sized jars
8. Eilleen's gallon can hold more cups that James's 3 quart water bottle.It can hold 4 more cups
Step-by-step explanation:
6. There are 96 fourth graders and each is supposed to get 1 cup of milk.
Hence, the number of cups of milk for all the fourth graders at the party is
96 × 1 cup of milk = 96 cups of milk.
Mr. Lee ordered 45 pints of milk for the fourth - grade party.
We have the conversion rate:
1 cup = 0.5 pints
Hence
1 cup = 0.5 pints
96 cups of milk = x
Cross Multiply
1 cup × x = 96 cups of milk × 0.5 pints
x = 96 cups of milk × 0.5 pints/1 cup
x = 48 cups of milk
a. Did Mr. Lee order the correct amount of milk?
No Mr Lee did not order the correct amount of milk.
b. if so, explain why you think he is correct. if not, how many pints of milk should he have ordered?
Mr Lee should have ordered for 48 pints of milk.
7. Daphne and Jordan made jam to sell at the market. Their jam is sold in pint - size jars.
They made 137 quarts but only sold 59 quarts.
The amount of quarts left is calculated as: 137 quarts - 59 quarts
= 78 quarts
We have conversion rate of
1 quart = 2 pints
The number of pint - size jars that are left is calculated as:
1 quart = 2 pints
78 quarts = x
Cross Multiply
1 quart × x = 78 quarts × 2 pints
x = 78 quarts × 2 pints/1 quart
x = 156 pints
The number of pint - size jars that are left 156 pints
8.
For James
James had a 3-quart water bottle.
1 quart = 4 cups
3 quarts = x
Cross Multiply
1 quart × x = 3 quarts × 4 cups
x = 3 quarts × 4 cups/1 quart
x = 12 cups
Hence, James 3 quart water bottle can hold 12 cups
For Eileen
Eileen bought 1-gallon jug.
1 gallon = 16 cups
Hence, Eileen's gallon can hold 16 cups
The difference between both containers is:
16 cups - 12 cups = 4 cups
Therefore, Eileen's gallon can hold more cups that James's 3 quart water bottle
It can hold 4 more cups
5x+2y = 19
1x + 4y=13
Answer:
{x,y} = {25/9,23/9}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = -4y + 13
// Plug this in for variable x in equation [1]
[1] 5•(-4y+13) + 2y = 19
[1] - 18y = -46
// Solve equation [1] for the variable y
[1] 18y = 46
[1] y = 23/9
// By now we know this much :
x = -4y+13
y = 23/9
// Use the y value to solve for x
Solve the following quadratic by
completing the square.
y = x2 + 10x + 10
Answer:
x = -5 - √15 or x = -5 + √15Step-by-step explanation:
[tex]y = x^2+10x+10\\\\y=x^2+10x+25-25+10\\\\y=(x+5)^2-15\\\\y=0\quad\iff\quad (x+5)^2-15=0\\\\(x+5)^2=15\\\\x+5=\pm\sqrt{15}\\\\x=-5-\sqrt{15}\quad or\quad x= -5+\sqrt{15}[/tex]
what is the answer????
Answer:
side LN is 28 units
Step-by-step explanation:
find the length of KN to be 21 through reverse pythagorean theorem and then subtract the square of 21 (441) from the square of 35 (1225) to get 784 and then find the square root of 784. that is the length of LN: 28
Jillian's puppy weighed 16 pounds at the age of 2 months. It weighed 60 pounds at the age of 8 months. What is the percent change in the puppy's weight?
Answer:the percent change in the puppy's weight= 275%
Step-by-step explanation:
Jillian's puppy Weight at 2 months =16 pounds
Jillian's puppy Weight at 8 months =60 pounds
percent change in the puppy's weight= change in weight / Old weight x 100
(60 pounds -16pounds ) / 16 x 100
44/16 x 100 = 275%
Alex makes $61,992 per year and pays about 25% of his gross monthly income in federal and state taxes. He wants to find an apartment to rent. Estimate how much he can afford to pay for rent each month. Then, determine how much money he will have after taxes and rent are paid.
Answer:
Rent each month = $1421
Amount left after rent and taxes monthly = $2453
Step-by-step explanation:
Gross salary; $61,992 per year
His gross pay per month will be;
61992/12 = $5166
Now, the standard recommended rule in budgeting for house rent is to use between 25% to 30% of your monthly pay for rent.
Now, let's adopt an average of 27.5%
Thus;
Amount he can afford for rent each month = 27.5% × 5166 = $1420.65 ≈ $1421
We are told he pays 25% of his gross monthly income in federal and state taxes.
Thus, amount spent on taxes each month = 25% × 5166 = $1291.5 ≈ $1292
Thus, amount he will gave left after rent and taxes = 5166 - (1421 + 1292) = $2453

How are finding the volume of a rectangular prism and a triangular prism alike
Answer:
the triangular prism is ⅓ the size of the rectangular prism. they have the same concept equation of:
rectangular prism - length×width×height
triangular prism - ½×length×width×height
they both have to multiply the base and height to find the volume
Answer:
Finding the volume of a rectangular and triangular prism are alike, one way is they use similar formula base x length x height. Another way is They both have rectangle in the prism.
