Write an equation of the line that is perpendicular to y=-3x+1 and passes through point (5,3).
Answer: There are two formulas that we will use the first one is the y=m x+b and the second one is finding the perpendicular line.
Step-by-step explanation:
the first one is
y=m x+b
y= 3 x -12
the second one is
first find the negative reciprocal of the slope of the original line and use the point slope formula y- y,= m(x - x1) to find the line perpendicular to
Y= 3 x 1
X= 5

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.

In Earth's southern hemisphere, the summer season is from December to March and winter is from June to September. The table shows the highest temperatures recorded at the South Pole for three different months.
Graph model:
South Pole Temperatures
Month Highest temperature (°F)
January 6
June –24
November –2
Each month's highest recorded temperature is plotted on the number line.
Which of these months had the lowest high temperature? (ignore this)
1. Write the three temperatures in order from least to greatest. Explain how you put the numbers in order.
2. Which month had the lowest high temperature?
3. Which month had the highest temperature?
Answer:
sorry explenation lang po kaya ko ☺ thanks for points
Step-by-step explanation:
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.
(-8)–(-13)? Answer plz
Answer:

Step-by-step explanation:
(-8)-(-13)= 5
Please Help?
If X = 5, what is the value of -2X + 2 + 5X + 8?
-2X + 2 + 5X + 8?
-2(5) + 2 + 5(5) + 8
-10 + 2 + 25 + 8
25
Answer: 25
Answer:
The answer would be 25.
Step-by-step explanation:
If x=5, that means:
-2(5)+2+5(5)+8
-10+2+25+8
-8+25+8
-17+8
25
Therefore, the value would be 25.

A class is having a water balloon tossing contest. There is a large tub of water. Gavin uses 3 1/5 quarts of water to fill some balloons, and Quinley uses 6 1/2 quarts to fill more balloons. Find the total change of volume of water in the tub
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:
Gavin uses (3 + 1/5) quarts of waterQuinley uses (6 + 1/2) quarts of water.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.

1. The ratio of red marbles to blue marbles
in a bag is 2 to 5. If there are 60 more
blue marbles than red marbles in the
bag, how many marbles are there all
together?
Answer:
84
Step-by-step explanation:
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.
solve for x pleaseeee

In the diagram below, AB and CB each have a length of 5 centimeters. If m<A=6(x-3) and m<C=4(x+1), determine the value of each angle of the triangle.
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.
-----------------------------
Segments AC and CB have the same length, thus, angles A and C have the same measure, and then:[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.
