. A large tree, b, removes 1.5 kg of pollution from the air each year. A small tree, s, removes 0.04 kg of pollution each year. An urban forest has 1,650 large and small trees. Together, these trees remove 1,818 kg of pollution each year. Which system of equations could be used to find the number of large and small trees in the forest?
Answer:
The system of equations are:
s + b = 1650.... Equation 1
0.04s + 1.5b = 1818........ Equation 2
The number of
Small trees = 450 trees
The number of Big trees = 1200 trees
Step-by-step explanation:
From the above question
Small trees = s
Large trees = b
An urban forest has 1,650 large and small trees.
Hence,
s + b = 1650.... Equation 1
s = 1650 -b
A large tree, b, removes 1.5 kg of pollution from the air each year. A small tree, s, removes 0.04 kg of pollution each year. Together, these trees remove 1,818 kg of pollution each year.
Hence:
0.04s + 1.5b = 1818........ Equation 2
We substitute 1650 - b for s
0.04(1650 - b) + 1.5b = 1818
66 - 0.04b + 1.5b = 1818
- 0.04b + 1.5b = 1818 - 66
1.46b = 1752
b = 1752 ÷ 1.46
b = 1200 trees
Solving for x
1650 - b = s
s = 1650 - 1200
s = 450 trees
3. Determine the slope of the line that has the following coordinates: (-3, 6) (4,-2)
-8/7
8/7
-7/8
12/7
Answer:
-8/7
Step-by-step explanation:
(-3, 6) & (4,-2)
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-2 - 6) / (4 - (-3))
Simplify the parentheses.
= (-2 - 6) / (4 + 3)
= -8 / 7
Simplify the fraction.
= -8/7
This is your slope.
Hope this helps!

yall its 9 i got it right on the test in edg
Step-by-step explanation:
The value of the variable 'x' in the arithmetic sequence 6, 9, 12, 15, x, .... will be 18.
What is an arithmetic sequence?A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.
Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
The sequence is given as,
6, 9, 12, 15, x, .....
The common difference between the succession term remains constant. Then the equation is given as,
15 - 12 = x - 15
Simplify the equation, then we have
15 - 12 = x - 15
3 = x - 15
x = 15 + 3
x = 18
The value of the variable 'x' in the arithmetic sequence 6, 9, 12, 15, x, .... will be 18.

Answer:
Blank 1: y=3x+10
Blank 2: y= 40
Step-by-step explanation:
Let the cost of gift wrap be y and the number of gifts be x.
Department
An upfront fee of $10 means that Mr Bentley needs to pay $10 first, and this $10 is only paid once on top of the cost of wrapping each gift.
y= 3x +10
Niece
A flat fee of $40 means that no matter how many gifts the niece wraps, Mr Bentley only pays $40.
y= 40
To find out when the two plans cost the same, equate the two equations together. Then, solve for x.
3x +10= 40
3x= 40 -10 (-10 on both sides)
3x= 30
x= 30 ÷3
x= 10
Thus when Mr Bentley has 10 gifts to be wrapped, the 2 plans costs the same.

A candelabra holds 5 identical cylindrical candles, each with a diameter of 6 centimeters and a height of 9 centimeters. How many cubic centimeters of wax are in all the candles on the candelabra combined?
Answer: [tex]1272.51\ cm^3[/tex]
Step-by-step explanation:
Given
diameter of each candle is [tex]d=6\ cm[/tex]
The height of each candle is [tex]h=9\ cm[/tex]
The volume of a cylinder is [tex]V=\pi r^2h[/tex]
The volume of each candle is
[tex]\Rightarrow V=\pi \times 3^2\times 9\\\Rightarrow V=254.502\ cm^3[/tex]
For 5 candles it is
[tex]\Rightarrow 5V=1272.51\ cm^3[/tex]
Total wax used for 5 candles is [tex]1272.51\ cm^3[/tex]

Write the linear equation in slope-intercept form given the following: (-4, 6); slope = -3/4
Answer:
6=-3/4x+(-4)
Step-by-step explanation:
The equation of any straight line, called a linear equation, can be written as: y= mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis. So for the given information you can see that they gave you your slope of -3/4 so you fill that in under the m. The point that would cross the y axis would be -4 because when you think of it on a graph you would see it as (-4 y) and (6 x). When you are writing linear equations you use the form y=mx+b.

A builder set up a wooden frame in which to pour concrete for a foundation to a house. The length of the wooden frame is 24 feet. The width is 32 feet. The diagonal is 40 feet. Which best describes the foundation?
Answer:
d) A foundation may be a rectangle : 24² + 32² = 40²
Step-by-step explanation:
P.S - The exact question is -
Given - A builder set up a wooden frame in which to pour concrete for a foundation to a house. The length of the wooden frame is 24 feet. The width is 32 feet. The diagonal is 40 feet.
To find - Which best describes the foundation?
a) A foundation can not be a rectangle : 24 + 32 ≠ 40
b) A foundation can not be a rectangle : (24 + 32)² ≠ 40²
c) A foundation can not be a rectangle : √24² + 32² ≠ 40²
d) A foundation may be a rectangle : 24² + 32² = 40²
Proof -
We have to check whether the shape of the frame is rectangle or not.
As we know that,
A diagonal divides the rectangle in two right angle triangles
So,
Given that Length = 24
Width = 32
Diagonal = 40
By applying Pythagoras theorem, we get
40² = 24² + 32²
So,
The correct option is - d) A foundation may be a rectangle : 24² + 32² = 40²

what is the exact volume of a cylinder with a radius of 7 inches and a height of 20 inches
Answer:
V = 3078.76 in³
Step-by-step explanation:
To find the volume of a cylinder, use this formula:
V = πr²h
V = volumer = radiush = heightPlug in the values you know.
V = π(7)²(20)
First let's evaluate the exponent.
7² = 49
V = π(49)(20)
Now let's multiply.
49 • π = 153.938
153.938 • 20 ≈ 3078.76
V = 3078.76 in³
This is your answer.
