Why are points important in geometry
Points are very important in geometry.
In fact, a point is the most basic figure in geometry.
A point has no size, only position.
Although it's basic, it's used all the time in geometry and it creates things.
For example, two points creates line segments.
Line segments are used in postulates and theorems.
Jane is saving to buy a cell phone
$35 a month from her allowance
Does it make sense to represent to
and the number of months with a
your answer.
She is given a $100 gift to start and saves
after 1 month, Jane has saved $135.Does it make sense to represent the relationship between the amount saved
ne constant rate? Why or why not? Explain.
Answer:
She saves the same amount of money, it doesn't make sense to represent the amount saved and number of months with one constant rate.
Step-by-step explanation:
Because the se amount is saved every month, it makes ot linear, and then unnecessary to represent the amount saved and the number of months with one constant rate.

Jessica want to slowly decrease her daily caloric intake, which is currently 2500 calories per day. She plans to decrease her calorie intake by 40 calories every 2 days for the next 30 days. Determine a reasonable domain and range for this situation.
Answer:
domain is (0, 30)
Range is (1900, 2500)
Step-by-step explanation:
We are told that Jessica plans to decrease her calorie intake by 40 calories every 2 days for the next 30 days.
This means that the domain of this period is between 0 days to 30 days.
Thus, the domain is (0, 30)
Now,she plans decrease of 40 calories every 2 days. This amounts to an average of 20 calories a day.
Which means that in a month of 30 days, she would have decreased her daily calorie intake by; 20 × 30 = 600 calories.
Since she is currently on 2500 calories per day, it means that the new targeted daily intake is; 2500 - 600 = 1900 calories.
Thus, the range for this situation would be between 1900 calories and 2500 calories.
Range = (1900, 2500)
If m∠OZQ = 125 and m∠OZP = 62, what is m∠PZQ
Answer:
63° or 173°Step-by-step explanation:
You didn't specify where the point P is so there are two posibilites:
1.
P₁Z is dividing angle OZQ
then:
m∠P₁ZQ = m∠OZQ - m∠OZP₁ = 125° - 62° = 63°
2.
P₂Z is outside angle OZQ
then
m∠P₂ZQ = 360° - (m∠OZQ + m∠OZP₂) = 360° - (125° + 62°) = 173°
You go shopping for some new shoes on a sales tax free weekend (yay no taxes!). You have a 20% off coupon. If you have a $100 to spend, what is the maximum price of the shoes you can buy with the coupon? Explain how you figure out your answer.
Answer:
$125
Step-by-step explanation:
With a 20% off coupon, the price you pay is 80% of the marked price. If that amount is $100, you have ...
$100 = 0.80p
p = $100/0.80 = $125
The maximum price of the shoes you can buy is $125.
_____
Check
20% of $125 is -.20×$125 = $25. When that is subtracted, the price you pay is ...
$125 -25 = $100
Answer:
$125
Step-by-step explanation:
let the maximum price be 'x'
[tex]x -( \frac{20}{100} \times x) = 100[/tex]
[tex]x - ( \frac{x}{5} ) = 100[/tex]
[tex] \frac{4x}{5} = 100[/tex]
[tex]4x = 500[/tex]
[tex]x = 125[/tex]

A football field measures 300 feet in length. It can also be expressed as approximately 5.7 times 10 Superscript n miles. If there are 5,280 feet in 1 mile, which is the most reasonable value of n? Negative 3 Negative 2 2 3
Answer:
-2
Step-by-step explanation:
300 ft * (1 mile)/(5280 ft) = 0.057 miles = 5.7 * 10^-2 miles
Answer:
The answer is b
Step-by-step explanation:
find the slope of the line through each pair of points (1/2,0) and (0,4/7)
The line crosses (1/2,0) and (0,4/7)
Let m be the slope of this line
● m = [0-(4/7)]/[(1/2)-0)]
● m = (-4/7)/(1/2)
● m = (-4×2)/7
● m = -8/7
So the slope of this line is -8/7

Find the Area of the parallelograms.
Answer:
2
Step-by-step explanation:
area of a parallelogram : b x h (base x height)
since there are no measurements, we are looking at the squares
im assuming that the squares are 1x1 squares
hence, for the base of the parallelogram, we are counting the squares
i added the halves together and got the answer 2
then we need to take the height
which im also assuming is 1
b x h = 1 x 2
a = 2

At a stop in New York City, 50 people board a subway every 10 minutes. After how long will 250 people have boarded a train at that stop? A. 20 minutes B. 40 minutes C. 50 minutes D. 1 hour
Answer:
C. 50 minutes
Step-by-step explanation:
each time, 50 people can aboard. to calculate how many times people aboard, divide 250 by 50, equals 5
each time to aboard takes 10 minutes, so multiply 5 by 10 equals 50minutes.
What is 325 .623 rounded to the nearest 10
The 325.623 round to the nearest 10 is 325.6.
What is round figures in maths?Rounding a number of means simplifying it while retaining its value close to what it was. The end output is less accurate but more usable. For instance, 73 rounded to the closest ten is 70, because 73 is closer to 70 than 80.
The tens' digit is the rule for rounding to the closest a hundred. If the number is five or more, round up. If the number is four or less, round down. Consider the number formed by the digits in the tens and one's columns when rounding to the nearest hundred.
To round to the next thousand, write down the multiple of 1000 closest to our number. The thousands' digit will either remain unchanged or rise by one.
Therefore, the nearest 10 is 325.6.

Triangle ABC is split into two triangles as shown: shaded and non-shaded.
If the area of the shaded triangle is twice the area of the non-shaded triangle, find the size of angle ACB, correct to 1 decimal place.
Answer:
26.6°
Step-by-step explanation:
The area of a triangle is given by (1/2) * (base) * (height). The two triangles share the same height, so in order for the shaded triangle to have twice the area, its base must be twice that of the non-shaded triangle.
The non-shaded triangle is a right triangle with two 45° angles, so it's an isoceles right triangle with a base equal to its height.
This means that the height of the shaded triangle is 1/2 of its base. Knowing that we can get the angle of ACB with:
tan⁻¹(1/2) ≈ 0.4636476 (in radians)
Convert to decimal angle:
0.4636476 * (180/π) ≈ 26.6°

Which statement below is true concerning the number 5/11?
Answer:
C. The number 5/11 is a rational number because it is a repeating decimal.
Step-by-step explanation:
The importance of this question is to distinguish a rational number from an irrational number.
A rational number can be written as a ratio or a set of repeating decimals.
An irrational number cannot be written as a ratio and cannot be represented by repeating decimals.
So out of the four options you have, the first two, A and B, are false, C is true, and D is false since rationality doesn't have anything to do with signs.

Let x represent the total income.
20% of the total amount = 300 --> 0.20x = 300
÷0.20 ÷0.20
x = 1500
Answer:
The total income is $1,500.
Step-by-step explanation:
$300 / 20% = $15 [ budget percent x 15 = budget amount in dollars]
Housing: 10 x 15 = $150
Food: 30 x 15 = $450
Fuel: 15 x 15 = $225
Clothing: 20 x 15 = $300
Health: 15 x 15 = $225
Miscellaneous: 10 x 15 = $150
Total Income: 150+450+225+300+225+150 = $1500

Both Galapagos islands and the Island of Nauru are on the equator, but the Galapagos islands are at 90°W where the Island of Nauru is at 166.50°E. How far is it from the Galapagos islands to Nauru traveling over the Pacific ocean along the equator, correct to the nearest km?
Answer:
11565 km
Step-by-step explanation:
The computation is shown below:
But before reaching the final solution first we need to do the following calculations
The angle lies between the Galapagos and Nauru is
= 90° + 166.50°
= 256.5°
Since the sum of angle is 360 degrees
So the major arc and the minor arc is
= 360° - 256.5°
= 103.50°
Now the angles lies between galapagos islands is
= 180° - 90°
= 90°
And, between the naura island is
= 180° - 166.50°
= 13.5°
Now the total of this two island is
= 90° + 13.5°
= 103.5°
The length is
[tex]= \frac{\pi r }{180^{\circ}} \times \theta\\\\ = \frac{6,400\pi}{180^{\circ}} \times 103.5^{\circ}[/tex]
= 11565 km
