help please!!!! also please explain how to solve equations with different variables in it (like 2k+3x= 30)
Answer:
C. j=2 and h=4
Step-by-step explanation:
Step 1: Create a system of equations for your problem based off what we know.
- we should know that the equation to find the perimeter of something is
[tex]P= 2l+2w[/tex] where P is the perimeter, l is the length, and w is the width.
- we know that the perimeter of Rectangle P is 20 inches and that the perimeter of Rectangle Q is 30
- we know the length and width of both rectangles
Using this information, lets set up our system.:
[tex]\left \{ {{20=2(j+4)+2h} \atop {30=2(3h)+2(j+1)}} \right.[/tex]
Step 2: Using the top equation we're going to try to solve for one of the variables. I chose to solve for variable j.
[tex]20=2(j+4)+2h[/tex]
Start by distributing 2 into j + 4.
[tex]20=2j+8+2h[/tex]
Now subtract 8 from both sides of the equation.
[tex]12=2j+2h[/tex]
Now isolate variable j by subtracting 2h from both sides of the equation.
[tex]12-2h=2j[/tex]
Now condense the equation into simple terms by dividing both sides by its GCF 2 then reorder to get j on the left.
[tex]j=6-h[/tex]
Step 3: Now that we solved for variable j we can now substitute j into one of our equations from the original system. I chose to use the bottom equation and chose to distribute it before substituting.
[tex]30=6h+2j+2[/tex]
Subtract two from both sides to isolate the variables
[tex]28=6h+2j[/tex]
Now we can plug j into our equation
[tex]28=6h+2(6-h)[/tex]
Step 4: Distribute 2 into 6-h
[tex]28=6h+12-2h[/tex]
Step 5: Combine like terms
[tex]28=4h+12[/tex]
Step 6: Subtract 12 from both sides of the equation
[tex]16=4h[/tex]
Step 7: Divide both sides by 4
[tex]4=h[/tex]
Now that we know that h=4 we can plug 4 into one of our earlier equations. I used j=6-h
[tex]j=6-4\\j=2[/tex]
Plug answers into either one of the original equations to check answer
A video rental store keeps a list of its top 15 movie rentals each week. This week the list includes 6 action, 4 comedies, 3 dramas, and 2 mysteries. The store manager removes a copy of each of the 15 movies from the shelf, then randomly selects 3 of the 15 to show on the display monitors in the store. What is the probability that she selected 2 comedies and 1 action movie?
Answer choices:
72/3375
96/3375
72/2730
96/2730
The probability that the store manager selects 2 comedies and 1 action movie is 96/3375.
Given that,
A video rental store keeps a list of its top 15 movie rentals each week.
Total = 15
Action movies = 6
Comedies = 4
When she selected three movies,
Probability of selecting an action movie = 6/15
Probability of selecting a comedy movie = 4/15
Probability of selecting one action and 2 comedies = 6/15 × (4/15)²
= 96/3375
Hence the required probability is 96/3375.

What is the approximate area of the shaded region? Use 3.14 for pi
Please do step by step...
Answer:
A. 20.86 square inches
Step-by-step explanation:
a)
We know that the formula for the area of a rectangle is Length x Height (A = LH).
Length (L) = 6 inches
Height (H) = 4 inches
So we incorporate our formula for the area of a rectangle into this situation:
Area (A) = 6 x 4
Area (A) = 24 in^2
b)
We know that the formula for the area of a circle is Pi x radius squared (A = πr^2).
Radius (r) = 1 inch
So we incorporate our formula for the area of a circle into this situation:
Area (A) = 3.14 x 1^2
Area (A) = 3.14 in^2
c)
We can see from the diagram that the shaded region come mainly from the rectangle. So to find the area of the shaded part, we can simply subtract the area of the circle, from the area of the rectangle (Area of rectangle - Area of circle = Area of shaded region).
Area of rectangle = 24 in^2
Area of circle = 3.14 in^2
So we incorporate our formula for the area of the shaded part into this situation:
Area (A) = 24 in^2 - 3.14 in^2
Area (A) = 20.86 in^2
Answer:
A

Equivalent to 8(t+8):
8t+64
(8*t)+(8*8)
Equivalent to 8t+8:
4t+8+4t
4(2t+2)
Equivalent to neither:
8t+16
(8+t)+(8+8)
Step-by-step explanation:
First we expand the bracket 8 (t + 8)
This gives us 8t + 64
Option 1:
8t + 16 is not an option, so it goes in the neither box.
Option 2:
8t + 64 is an option, so it goes in the 8 (t + 8) box.
Option 3:
(8 * t) + (8 * 8) is an option, so it goes in the 8 (t + 8) box.
Option 4:
4t + 8 + 4t is an option, so it goes in the 8t + 8 box.
Option 5:
4 (2t + 2) is an option, so it goes in the 8t + 8 box.
Option 6:
(8 * t) - (8 * 8) is not an option, so it goes in the neither box.

Answer:
96cm
Step-by-step explanation:
front/back triangles: (4 * 3) / 2 = 6cm
bottom rectangle: 4 * 7 = 28cm
side rectangle (left): 3 * 7 = 21cm
slanted rectangle: pythagoras - 3^2 + 4^2 = x^2
9 + 16 = x^2
25 = x^2
square root of 25 = 5
x = 5
7 * 5 = 35cm

What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is given as side².
We have,
To find the area painted green, we need to calculate the areas of the square and the triangle and then multiply by 14.2% (or 0.142).
The area of the square is simply the length of one side squared, so:
Area of square = (7 cm)² = 49 cm²
The area of the triangle is one-half the base times the height, so:
Area of triangle = (1/2)(7 cm)(3 cm) = 10.5 cm²
Therefore, the total area of the figure is the sum of the area of the square and the triangle:
Total area = 49 cm² + 10.5 cm² = 59.5 cm²
Finally, to find the area painted green, we multiply the total area by 14.2%:
Area painted green = 0.142 x 59.5 cm² ≈ 8.47 cm²
Therefore,
Approximately 8.47 cm² of the figure is painted green

Wan has 22 bulbs of the same shape and size in a box. The colors of and amounts of the bulbs are shown below:
6 blue bulbs
9 red bulbs
7 orange bulbs
Without looking in the box, Wan takes out a bulb at random. He then replaces the bulb and takes out another bulb from the box. What is the probability that Wan takes out an orange bulb in both draws? (5 points)
Answer: A
Step-by-step explanation:
This type of question is compound probability and it involves independent variables because the outcome of 1 event doesn't impact the probability of the next one.
the probability of taking an orange bulb is 7/22. Since he put that bulb back in the box, the probability of taking an orange bulb again, doesn't change. So the "compound probability " is 7/22x7/22= 49/484.
