The slope of the line that passes through the points (1, -2) and (3, -5) is -3/2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We need to find slope of line passing through the points (1, -2) and (3, -5)
m= -5-(-2)/3-1
=-5+2/2
=-3/2
Hence, the slope of the line that passes through the points (1, -2) and (3, -5) is -3/2.

A traffic helicopter descends 107 meters to be 407 meters above the ground, as illustrated in the diagram to the right. Write an equation to describe the situation using h as the original height of the helicopter. What was the original height of the helicopter?
Step-by-step explanation:
Its 514 because 107+407 is 514
Answer:
h = 514 meters
Step-by-step explanation:
If the helicopter descends 107 meters to then be 407 meters above the ground, then it was originally 107 meters above 407 meters.
h-107=407
add 107 to both sides
h = 107+407
h = 514

A conjecture and the paragraph proof used to prove the conjecture are shown.
Given: ABCD is a parallelogram. Segment DC bisects angle B D E. Prove: angle 1 is congruent to angle 3. Parallelogram A B C D. Two rays D B and D E share endpoints at vertex D. Ray D B extends diagonally up to the right from D C at vertex D forming interior angles A B D and B D C. Angle A B D is labeled 1 and angle B D C is labeled 2. Ray D E extends diagonally down to the right from segment D C at vertex D forming an exterior angle C D E. Angle C D E is labeled 3.
Drag an expression or phrase to each box to complete the proof.
It is given that ABCD is a parallelogram, so AB¯¯¯¯¯∥DC¯¯¯¯¯ by the definition of parallelogram. So, ∠1≅ ∠2 by the alternate interior angles theorem. It is also given that DC¯¯¯¯¯ bisects ∠BDE, so ∠2≅ Response area by the Response area. Therefore, Response area ≅∠3 by the Response area.

Incomplete questions. Here's the complete question:
Alexandra made a tally chart shown below. A 2-column table with 5 rows. Column 1 is labeled Books Read in the Last Month with entries 1, 2, 3, 4, 5. Column 2 is labeled Tally with entries 2, 5, 3, 1, 2.
Which would be a good statistical question based on the tally chart?
How many people read three books in the last month?How many people read one or two books in the last month?Did you read in the last month?How many books did you read in the last month?Answer:
How many books did you read in the last month?
Step-by-step explanation:
A tally chart is a numbering system used to quickly record data. It usually involves filling a chart with vertical dashes that represents the number of times an action or information is observed.
Therefore, by asking, "How many books did you read in the last month?", Alexandra would be able to get the answer by means of a tally chart which would show the number of times that action occurred.
a formula for 6 gallons of light green paint uses 3/8 gallon of white paint. Liam has 9/16 gallon does Liam have enough white paint to make 8 gallons of light green paint?
Given:
6 gallons of light green paint uses [tex]\dfrac{3}{8}[/tex] gallon of white paint.
Liam has [tex]\dfrac{9}{16}[/tex] gallon of white paint.
To find:
Whether Liam have enough white paint to make 8 gallons of light green paint.
Solution:
Here, 6 gallons of light green uses [tex]\dfrac{3}{8}[/tex] gallon of white paint.
So, the white paint for 1 gallon of light green [tex]=\dfrac{\dfrac{3}{8}}{6}[/tex]
[tex]=dfrac{3}{8\times 6}[/tex]
[tex]=\dfrac{3}{48}[/tex]
[tex]=\dfrac{1}{16}[/tex]
It means, 1 gallons of light green uses [tex]\dfrac{1}{16}[/tex] gallon of white paint.
White paint for 8 gallon of light green [tex]=8\times \dfrac{1}{16}[/tex]
[tex]=\dfrac{8}{16}[/tex]
She has [tex]\dfrac{9}{16}[/tex] gallon of white paint, which is greater than [tex]=\dfrac{8}{16}[/tex] gallons.
Therefore, Liam have enough white paint to make 8 gallons of light green paint.
If Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint
Given that 6 gallons of light green paint use 3/8 gallon of white paint, this can be expressed as:
3/8 gallons of white paint = 6 gallons of light green
We are to determine if 9/16 gallons will be enough to make 8 gallons of light green paint. This can be expressed as
9/16 gallons of white paint = x
Divide both expressions
3/8 * 16/9 = 6/x
2/3 = 6/x
Cross multiply
2x = 3 * 6
2x = 18
x = 18/2
x = 9
This shows that if Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint

Step-by-step explanation:
I multiply by splitting the numbers into digits. So for the 90, in my head I did 5 × 90, which is 450. Then I did 2 × 5, this is 10. Now I added those up to make 460. Considering the 92 is negative, the answer will also be negative.
You plant a tomato plant in your garden. It starts at 8 inches tall. After 1 week, it grows to 11 inches tall. After two weeks, it is now 14 inches tall. After 3 weeks, the plant is 17 inches tall. Write a linear equation that represents this model. How tall is the tomato plant after 56 weeks?
Answer:
The tomato plant is 176 inch tall after 56 weeks.
Step-by-step explanation:
x ⇒ weeks and y ⇒ inch.
Week 0 the tomato plant starts at 8 inch tall, week 1 it grows to 11 inch tall, week 2 it grows to 14 inch tall, week 3 it grows to 17 inch tall, week 56 is ? inch tall. So, every week (x) the tomato plant grows 3 inch (y).
y = 3x + 8
y = (3 × 56) + 8
y = 168 + 8
y = 176 inch
[tex]h(n) = 8 + 3n[/tex]
Using the function, after 56 weeks, the height of the plant is of 176 feet.The linear model for the height after n weeks has the following format:
[tex]h(n) = h(0) + an[/tex]
In which:
h(0) is the initial height. a is the rate of change.Starts at 8 inches tall, thus h(0) = 8. Each week the height increases 3 inches, thus, a = 3, and the model is:
[tex]h(n) = 8 + 3n[/tex]
After 56 weeks, the height is of h(56), thus:
[tex]h(56) = 8 + 3(56) = 176[/tex]
176 inches tall after 56 weeks.

Step-by-step explanation:
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 30 x 40 = 600 m²
Area of a square = side length x side length
⇒ area of the square = 30 x 30 = 900 m²
Surface area of square-base pyramid = area of 4 triangles + area of square
⇒ SA = 4 × 600 + 900 = 2400 + 900 = 3300 m²

estimate the area of the circle. use 3.14 3.14 or 22 7 227 for π π.
Answer:
615.44
Step-by-step explanation:
If the diameter is 28, that means the radius is 14.
The formula for the area of a circle is pi x radius to the power of 2. So, 14 to the power of 2 (or 14 x 14) equals 196. 196 x 3.14 (pi) = 615.44
The estimated area of the circle is about 615.44 cm² or 616 cm², depending on which value you use for π.
How to find the area of a circle?Suppose the circle has radius of 'r' units, then, its area is given as:
[tex]A = \pi \times r^2[/tex] sq. units
Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:
[tex]\pi \times (\dfrac{d}{2})^2[/tex] sq. units
We are given that;
Diameter=28cm
Now,
In this case, the diameter of the circle is 28 cm, so the radius is half of that:
r = 28 / 2 = 14 cm
Plugging this value into the formula, we get:
A = π × 14²
Now we can use either 3.14 or 22/7 for π. Let’s use both and compare:
A ≈ 3.14 × 14² ≈ 3.14 × 196 ≈ 615.44 cm²
Or
A ≈ (22/7) × 14² ≈ (22/7) × 196 ≈ (4312/7) cm² ≈ 616 cm²
Therefore, by the area of circle the answer will be 615.44 cm² or 616 cm², depending on which value you use for π.

The dilated cone's with surface area of 2,250π in^2 has a volume of about 12500π in³
What is dilation?
Dilation is the increase or decrease in the size of a figure.
The cone has surface area 360π in² and volume 800π in^3. the cone is dilated, and the surface area of the dilated cone is 2,250π in^2.
Hence:
Scale factor² = dilated cone area / cone surface area
scale factor² = 2250π / 360π
Scale factor = 2.5
Volume of dilated cone = 2.5³ × 800π = 12500π in³
The dilated cone's with surface area of 2,250π in^2 has a volume of about 12500π in³
