Answer:
$95
Step-by-step explanation:
If 1 plant is $12 each, 17 plants will be
= 17($12)
= $204
Substitute the number of trees for x
The total cost of both is $964
Hence,
17($12) + 8(x) = $964
$204 + 8x = $964
Collect like terms
8x = $964 - $204
8x = $760
Divide both sides by 8
8x/8 = 760/8
x = $95
What is the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 2:3? m
The y-coordinate of the point that divides the directed line segment from J to K into a ratio of is 5.
The coordinates of point that divides the line segment into m:n ratio can be obtained as follows,
Coordinates of point = [tex](\frac{mx_{2}+ nx_{1} }{m+n} \frac{my_{2}+ ny_{1}}{m+n} )[/tex]
The coordinate of point J is (-3,1)
The coordinate of point K is (-8,11)
Consider the point that divides the line segment into 2:3 ratio as P(x,y).
The coordinates of point that divides the line segment into 2:3 ratio can be calculated as follows,
[tex]Coordinates of P = (\frac{3(-3)+2(-8)}{2+3}, \frac{3(1)+2(11)}{2+3} )[/tex]
[tex]= (\frac{-9-16}{5}, \frac{3+22}{5} )\\\\= (\frac{-25}{5} \frac{25}{5} )[/tex]

Which volume unit is smaller?
cubic millimeter cubic centimeter
Cubic millimeter volume unit is smaller.
You would multiply a measurement in cubic centimeters by 1,000 to translate it to cubic millimeters. This makes sense because you would anticipate needing a lot more cubic millimeters to fill the same space because a cubic centimeter is greater than a cubic millimeter.
Volume:
The total number of cubic units that a cube occupies in three dimensions is its volume. Six faces, twelve edges, and eight vertices make up the three-dimensional shape of a cube. Therefore, the area encircled by a cube's six faces is considered to equal its volume. It differs from 2D shapes in that it adds a third dimension, known as height or thickness, in addition to length and breadth. Since the product of a cube's length, width, and height determines its volume. Cubic units are used to measure it. The volume of a cube increases as the value of its dimensions increases.

If you are tossing a six-sided die, what is the probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss?.
The probability of getting either 1 or 2 on first and second toss is 1/9
How to calculate the probability?
Probability is numerical description for how likely something is to happen. To know probability something event we just divide no the outcome by total possible of the outcome.
The probability of either 1 or 2 side on first toss is
= no the outcome / total possible the outcome
= 2/6
= 1/3
For second toss is same as first toss
= 2/6
= 1/3
Since the second toss is independent, it is called an independent event. So, we just need to multiply the probability on the first toss by the probability on the second toss,
= 1/3 * 1/3
= 1/9
Thus, the probability of getting either 1 or 2 on first and second toss is 1/9

How can a image be reflected?
Behind a mirror's glass, people can see a reflection of themselves. The shiny surface creates that image when light rays strike it and reflect or bounce back, creating a "mirror image." Contrary to popular belief, the reflection is not mirrored from left to right as many people believe.
The coordinates of the point A is (-3,-2)
The rule of reflection over x-axis is
(x,y)→(x,-y)
So the point A after reflecting over the x-axis becomes
A(-3,-2)→ A(-3,2)
To move the point P(x,y), a units right and b units up we use
P(x+a,y+b)

triangle with side of 8 and 11 and angle of 38
The area of the triangle is 43.81 square units
The side a = 8 units
The side b = 11 units
The perimeter of the triangle = 32 units
First we have to find the third side of the triangle
a + b + c = 32
Substitute the values in the equation
8 + 11 + c = 32
19 + c = 32
c = 32 - 19
c = 13 units
Then the area of the triangle = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
The value of s = (a + b + c) / 2

Step-by-step explanation:

Answer:
The answer is x = 6. If you want to solve the equation by inputting the x and y value, then take the x value and input it into the equation as well as the y value.
Step-by-step explanation:
To solve this equation, plug in the value equal to y and solve for x. The first thing you have to do is make the equation -2 = 4x - 20, since we already have the value for y which is given in the question. Then add 20 to both sides of the equation. We now have 18 = 3x, divide both sides by 3 and you have your answer.

How to determine the parametric equations of the curve?A parametric equation is defined as a type of equation that employs an independent variable called a parameter (often denoted by t)
Given: The line with slope -4, passing through (-10, -20)
We can use the given properties of the curve to describe it parametrically as follows
The slope of -4 implies that if y decreases by 4, x increases by 1 i.e slope = Δy/Δx = -4/1. Thus, we have
x = -10 + 1t
y = -20 - 4t
Therefore, the parametric equations are x = -10 + 1t and y = -20 - 4t. So (x(t) , y(t)) = (-10 + 1t, -20 - 4t)

What value of x is in the solution set of the inequality 4x - 12 ≤ 16 + 8x?
O-10
997
-9
-8
O-7
Answer:
-7
Step-by-step explanation:
Given inequality:
[tex]4x - 12 \leq 16 + 8x[/tex]
Subtract 4x from both sides:
[tex]\implies 4x - 12-4x \leq 16 + 8x -4x[/tex]
[tex]\implies -12\leq 16+4x[/tex]
Subtract 16 from both sides:
[tex]\implies -12-16\leq 16+4x-16[/tex]
[tex]\implies -28\leq 4x[/tex]
[tex]\implies 4x \geq -28[/tex]
Divide both sides by 4:
[tex]\implies 4x \div 4 \geq -28 \div 4[/tex]
[tex]\implies x \geq -7[/tex]
This means that x is equal to or greater than -7.
Therefore, the value of x that is in the solution set of the inequality is -7 as -10, -9 and -8 are all less than -7.
Answer:
x ≥ -7
Step-by-step explanation:
Given inequation,
→ 4x - 12 ≤ 16 + 8x
Then the value of x will be,
→ 4x - 12 ≤ 16 + 8x
→ 4x - 8x ≤ 16 + 12
→ -4x ≤ 28
→ x ≥ 28/-4
→ [ x ≥ -7 ]
Hence, the value of x is -7.
X1. A restaurant owner keeps track of the food
prepared for guests for several days. Based on this
data, what is the constant of proportionality, if any
for this scenario? Show or explain how you know.
Vegetables Guests
Prepared

The constant of proportionality is the ratio of the number of guests to the food prepared is 0.8.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given tabel,
Suppose the number of guest ∝ food prepared.
Take the first data,
12 ∝ 15
12 = k(15)
k = 12/15 = 0.8
Hence "The constant of proportionality is the ratio of the number of guests to the food prepared is 0.8".
