Have a good day!!

We want to find the total change in the volume of water of a tub, given that we know how much water is used.

The change in volume is: -(9 + 7/10) quarts.

To find the change in volume, we need to find the total volume of water used.

We do know that:

The total amount used is the sum of the two quantities above, we get:

(3 + 1/5) quarts + (6 + 1/2) quarts

(3 + 6 + 1/2 + 1/5) quarts

(9 + 7/10) quarts.

So the change in volume is related to this, and we should write:

Final Volume - Initial Volume = -(9 + 7/10) quarts.

Where the negative sign is because at the end we have less volume than at the beginning.

Answer:

Exact area = 1800 - 450pi  square cm

Approximate area = 387 square cm

I used 3.14 for pi to get the approximate value.

============================================================

Explanation:

Check out the diagram below.

As the diagram shows, the largest radius possible is half of the shortest dimension of this rectangle. So the radius of each identical circle is 30/2 = 15 cm. The radius cannot exceed this value, or else the circle will spill outside the rectangle.

The area of one circle would be

A = pi*r^2

A = pi*15^2

A = pi*225

A = 225pi

Two identical circles like this combine to a total area of 2A = 2*225pi = 450pi square cm.

The area of the brown shaded region in the figure, aka the amount of cardboard leftover, is exactly 1800 - 450pi. The 1800 is from the computation of 60*30 = 1800, which is the area of the original rectangle before we made any cuts.

If we wanted to find the approximate area, then we could use pi = 3.14 to get

1800 - 450pi = 1800 - 450*3.14 = 387

The approximate area remaining is 387 square cm. This value is approximate because pi = 3.14 is approximate. If you were to use more decimal digits of pi, then you'd get some other approximate area.

Cross multiply to solve for the red marbles

Let x = the number of red marbles

2/5 = x/60

Cross multiply

2(60)/5 = x

x = 24 which is the number of red marbles.

60 blue plus 24 red = 84 total marbles.

Answer & Step-by-step explanation:

The main note to remember here is that the square root of 64 can be positive 8 or negative 8, we don't know which was used, so we give TWO answers.

Considering that angles A and C are equal, and the sum of the internal angles of a triangle is 180º, we have that:

The measure of angle A is of: 48º.

The measure of angle B is of: 84º.

The measure of angle C is of: 48º.

-----------------------------

[tex]6(x - 3) = 4(x + 1)[/tex]

[tex]6x - 18 = 4x + 4[/tex]

[tex]2x = 22[/tex]

[tex]x = \frac{22}{2}[/tex]

[tex]x = 11[/tex]

[tex]6(11 - 3) = 6(8) = 48[/tex]

The measure of angle A is of: 48º.

The measure of angle C is of: 48º.

The sum of the internal angles of a triangle is of 180º, and this is used to find the measure of angle B.

[tex]mA + mB + mC = 180[/tex]

[tex]2(48) + mB = 180[/tex]

[tex]mB = 84[/tex]

The measure of angle B is of: 84º.

Task

Here are the low temperatures (in Celsius) for one week in Juneau, Alaska:

Monday Tuesday Wednesday Thursday Friday Saturday Sunday

5 -1 -6 -2 3 7 0

Arrange them in order from coldest to warmest temperature.

On a winter day, the low temperature in Anchorage was 23 degrees below zero (in ∘C ) and the low temperature in Minneapolis was 14 degrees below zero (in ∘C ). Sophia wrote,

Minneapolis was colder because −14<−23.

Is Sophia correct? Explain your answer.

The lowest temperature ever recorded on earth was −89∘C in Antarctica. The average temperature on Mars is about −55∘C. Which is warmer, the coldest temperature on earth or the average temperature on Mars? Write an inequality to support your answer.

IM Commentary

The purpose of the task is for students to compare signed numbers in a real-world context. It could be used for either assessment or instruction if the teacher were to use it to generate classroom discussion.

Solution

Let’s begin by plotting them all on the same number line.

Sol_2_ec6fb38ef3896587f51b9afceb07f705

The number line has positive numbers to the right of zero and negative numbers to the left of zero. This means that numbers farther to the right are always greater than those to the left. In terms of temperature, the coldest temperature (the least number) is all the way to the left, and the warmest temperature (the greatest number) is all the way to the right.

We can now list the temperatures from coldest to warmest:

−7,−6,−2,−1,0,3,5

Sophia is incorrect. It is common for students to compare negative numbers as if they were positive and to assume that the one with the greatest magnitude is the greatest number. However, −23 is to the left of −14 on the number line, and so it is less than −14. Thus

−23<−14

and Anchorage was colder.

Again, the coldest temperature corresponds to the least number. So the warmest temperature corresponds to the greatest number. Since

−55>−89

the average temperature on Mars is warmer than the coldest temperature on Earth.
