A 2 quart carton of chocolate milk costs $1.40.
What is the price per pint?

Answers

Answer 1

Answer: 0.35 is the answer!!

Answer 2

Answer:

Answer:

If i am correct 0.35 per pint.

Step-by-step explanation:

As there is 2 pints in a quart you multiply 2x2 ( the amount of quarts) to get 4. Then you divide the price of $1.40 by 4.

approximately 93 million miles Definition of astronomical unit. For general reference, we can say that one astronomical unit (AU) represents the mean distance between the Earth and our sun. An AU is approximately 93 million miles (150 million km). It's approximately 8 light-minutes.

Lynette has a metal doorstop with the dimensions shown. Each cubic centimeter of the metal in the doorstop has a mass of about 8.6 grams. Find the volume of the metal in the doorstop. Then find the mass of the doorstop.(Picture is provided)

Answers

Answer:

The answers are:

Volume: 75 cubic centimeters

Mass: 645 grams

Step-by-step explanation:

In order to determine both volume and mass of the doorstop, we have to know the formulas of a triangular prism.

I have attached an image that shows some formulas about triangular prism.

As we see in the image, a triangular prism consists basically in a triangular face and its projection.

So, using the variables and formula of the image:

B=10 cm

H=6 cm

L=2.5 cm

$V=(1)/(2)*B*H*L\nV=(1)/(2)*10*6*2.5\nV=75$

Then, we know the density of the metal that is:

δ= $8.6 (gr)/(cm^3)$

So, the mass of the doorstop is:

m=δ*V

m=8.6 $(gr)/(cm^3)$ * 75 $cm^3$

m=645 gr

Finally, the volume is 75 $cm^3$ and the mass 645 gr

75 is the volume. 510 is the mass.

For a field trip, 4 students rode in cars and the rest filled nine buses. How many students went in each bus if 472 students were on the trip

Answers

Answer:

Step-by-step explanation:

only 4 students went in the cars. So 472-4=468.

You have 9 buses.

So 468÷9=52

SOS help i can't figure out this math problem

Answers

You would subtract each term of g(x) from f(x)

f(x) = 9x^3 + 2x^2 - 5x + 4
g(x) = 5x^3 - 7x + 4

9x^3 - 5x^3 = 4x^3

2x^2 - 0 = 2x^2

-5x - (-7x) = 2x

4 - 4 = 0

FINAL ANSWER:
4x^3 + 2x^2 + 2x

Do you have any info on adding and dividing fractions?

Answers

When you add fractions, you NEED to have the same denominator.

When you divide fractions, you do NOT need to have the same denominator.

$(a)/(c) + (b)/(c) = \boxed{\bf{(a+b)/(c)}}$

$(a)/(b) / (c)/(d) = (a)/(b) * (d)/(c) = \boxed{\bf{(ad)/(bc)}}$

a, b, c, and d are variables. You can replace them with any number.

adding and dividing fractions:

To add (and subtract) fractions, we need the same denominator. If both fractions that you are adding (or subtracting) do not have the same denominator, you will have to find the least common denominator of both of them.
If the fractions are:
$(2)/(3)$ + $(1)/(2)$
3 × 1 = 3 2 × 1 = 2
3 × 2 = 6 2 × 2 = 4
2 × 3 = 6
The least common denominator is 6
$(2*2)/(3*2)$ + $(1*3)/(2*3)$
$(4)/(6) + (3)/(6)$ = $(7)/(6)$ or $1(1)/(6)$

For diving fractions, you do not need common denominators
You can multiply the first fraction by the second fraction's reciprocal.
