What is the perimeter of the composite figure?
Answer: 96 cm
Step-by-step explanation:
The perimeter is the combined sum of the sides.
So 18 + 22 + 3 + 8 + 6 + 15 = 72
To find the 2 missing sides we use the information we already have.
On the top, we can see 18 is overall the largest line from the missing side.
So we'll need to subtract something from 18.
15 - 8 = 7 ( Inferencing )
18 - 7 = 11 ( length of the top missing side )
22 - 9 = 13
11 + 13 + 72 = 96 cm
Answer: The perimeter is 85 cm
Step-by-step explanation:
To find the perimeter you will need to add the distance around the shape.
But there seem to be one missing side .
To find that missing side we will have to add 3cm and 6 cm then subtract it from 22.
3 + 6 = 9
22 - 9 = 13
Now add the distance around the shape plus the 13.
22 + 15 + 6 + 8 + 13 + 3 + 18 = 85

Answer:
The actual dimensions would be 3.375 feet by 3.5 feet. The area of the room would be 11.8 square feet.
Step-by-step explanation:
A shipping container will be used to transport several 80-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 26500
kilograms. Other shipments weighing 6300 kilograms have already been loaded into
the container. Write and solve an inequality which can be used to determine x, the
number of 80-kilogram crates that can be loaded into the shipping container.
Answers:
The inequality to solve is [tex]80x+6300 \le 26500[/tex]The solution to the inequality is [tex]x \le 252.5[/tex]Interpretation: The most crates we can load is 252 since we can only load a positive whole number of crates, and because 253 is too many.==============================================================
Explanation:
x = number of 80-kilogram crates
x is some positive whole number
1 crate weighs 80 kilograms, so x of them will weigh 80x kilograms.
This is added on top of the 6300 kg from the other cargo already on board.
We have a total weight of 80x+6300. Let's call this T.
So T = 80x+6300
We want T to be 26500 or smaller. Otherwise, we've gone over capacity.
This must mean we want [tex]T \le 26500[/tex] which is the same as saying [tex]80x+6300 \le 26500[/tex] after replacing T with 80x+6300.
---------------------------
Let's follow PEMDAS in reverse to isolate x
[tex]80x+6300 \le 26500\\\\80x+6300-6300 \le 26500-6300 \ \text{ ... subtract 6300 from both sides}\\\\80x \le 20200\\\\\frac{80x}{80} \le \frac{20200}{80} \ \text{ ... divide both sides by 80}\\\\x \le 252.5\\\\[/tex]
The inequality sign stays the same the entire time. It would only flip if we divided both sides by a negative number.
In the last step, we get a decimal value. However, as stated earlier, x is a positive whole number.
We cannot round to 253 because that's too high. We can check x = 253 is too high by noticing that...
80x+6300 = 80*253+6300 = 26,540
which is over the 26,500 mark by 40 kg
So we must round down to the nearest whole number and find that x = 252 is the largest x value possible. Let's check to see if we're under the weight limit
80x+6300 = 80*252+6300 = 26,460
We're under the 26,500 weight limit (with 40 kg to spare)
In short, the most crates that we can load is 252 crates in addition to the other cargo that collectively weighs 6300 kg (which may or may not consist of those 80-kilogram crates).

Kaylee surveyed 920 of the students in her school about their favorite color. 95% said
their favorite color was blue. How many students' favorite color was blue?
Answer:
x = 874
Step-by-step explanation
Set up your equation like this: Part/whole = percent/100
Assign the variable x to the unknown part of the equation and add in the known numbers:
So in this situation it would be: x/920 = 95/100
Solve for x:
100 times X = 920 times 95. (cross multiply)
That leaves you with 100x = 87,400
Divide both sides by 100:
x = 874
Draw graph of straight lines to find approximate solution to these simultaneous equations . y = 3x + 7 and 2y + x = 2
Answer:
(-1.714, 1.857)
Step-by-step explanation:
Here, we want to find the approximate solution to the system of linear equations
We start by plotting the graph of the lines
We have the plot as shown below;
the red line represents the first equation while the blue line represents the second equation
We have the solution as the point at which the two lines meet
The solution to this is;
(-1.714, 1.857)
Write an equation in slope-intercept form of the line that passes through the points (-2, - 11) and (3,9).
The equation is y=
Answer:
y = 4x - 3
Step-by-step explanation:
(-2, -11) & (3, 9)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(9 - (-11)) / (3 - (-2))
Simplify the parentheses.
= (20) / (5)
Simplify the fraction.
20/5
= 4
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 4x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 9). Plug in the x and y values into the x and y of the standard equation.
9 = 4(3) + b
To find b, multiply the slope and the input of x(3)
9 = 12 + b
Now, subtract 12 from both sides to isolate b.
-3 = b
Plug this into your standard equation.
y = 4x - 3
This is your equation.
Check this by plugging in the other point you have not checked yet (-2, -11).
y = 4x - 3
-11 = 4(-2) -3
-11 = -8 - 3
-11 = -11
Your equation is correct.
Hope this helps!
I need help with my math practice problems

Solve the system.
3x + 2y + 4z = 11
2x – y + 3z = 4
5x – 3y + 5z = -1
Enter your answer as an ordered triple.
Someone help please!!
Answer: (x, y, z) = (-3, 2, 4)
In other words, x = -3, y = 2 and z = 4.
You'll enter the number only into each box.
===============================================================
Explanation:
There are a few routes we can take to solve this. I'll use substitution.
First let's isolate y in the second equation.
2x - y + 3z = 4
2x + 3z = 4+y
4+y = 2x+3z
y = 2x+3z-4
This is then plugged into the first equation
3x+2y+4z = 11
3x+2( y )+4z = 11
3x+2( 2x+3z-4)+4z = 11 .... replace y with 2x+3z-4; since y = 2x+3z-4
3x+4x+6z-8+4z =11
7x+10z-8 = 11
7x+10z = 11+8
7x+10z = 19 .... we'll call this equation (4) and come back to this later
--------------------------------------
Move onto the third equation (of the original equations given)
Plug in y = 2x+3z-4
5x - 3y + 5z = -1
5x - 3( y ) + 5z = -1
5x - 3( 2x+3z-4 ) + 5z = -1
5x - 6x - 9z + 12 + 5z = -1
-x - 4z + 12 = -1
-x - 4z = -1-12
-x - 4z = -13 ..... let's call this equation (5)
--------------------------------------
To recap, we found equation (4) and equation (5) to be
7x+10z = 19-x - 4z = -13We can then solve for x in equation (5) like so
-x - 4z = -13
-x = -13 + 4z
-x = 4z - 13
x = -(4z - 13)
x = -4z + 13
This is then plugged into equation (4)
7x+10z = 19
7(-4z+13)+10z = 19 .... note how we now have one variable
-28z+91+10z = 19
-18z+91 = 19
-18z = 19-91
-18z = -72
z = -72/(-18)
z = 4
We can use this value of z to find x
x = -4z+13
x = -4(4)+13
x = -16+13
x = -3
Use the values of x and z to find y. We'll revisit the first equation in which we isolated y
y = 2x+3z-4
y = 2(-3)+3(4)-4
y = -6+12-4
y = 6-4
y = 2
So overall, the solution to this system is (x, y, z) = (-3, 2, 4)
-------------------------------
Checking the answer:
We'll replace x,y,z with the values we found.
In the first equation, 3x+2y+4z = 11 becomes 3(-3)+2(2)+4(4) = 11 and that simplifies to 11 = 11. In other words, the expression 3(-3)+2(2)+4(4) turns into 11. This confirms the first equation.Repeat the same idea for the second equation. We have 2x-y+3z=4 turn into 2(-3)-2+3(4) = 4 and that simplifies to 4 = 4. The answer is verified here. The third equation 5x-3y+5z = -1 becomes 5(-3)-3(2)+5(4) = -1 which simplifies to -1 = -1. We get a true equation here as well.Since all three equations are true when (x, y, z) = (-3, 2, 4), this verifies the answer completely. This is the only solution to the system. The system is independent and consistent.

Answer:
Another ratio that is equivalent to this is 7:2.
Step-by-step explanation:
If we divide both sides by 6, we get 7 and we get 2. Since 42 comes first, we put the 7 in place of the 42. Then we replace 12 with 6. After this, we get the ratio 7:2.

How many 3-inch thick bags of mulch should Noemi buy to cover 100 square feet at a depth of 4 inches? The length is 3.2ft and the width is 2.5ft.
Answer:
Approximately 17 bags.
Step-by-step explanation:
The length of the bag of mulch = 3.2 ft
The width of the bag of mulch = 2.5 ft
The thickness of the bag of mulch = 3 inch = 0.25 ft
Volume of a bag of mulch = length x width x thickness
= 3.2 x 2.5 x 0.25
= 2 cubic feet
So that, the volume of a bag of mulch is 2 cubic feet.
The area to be covered = 100 square feet
The depth of the area = 4 inches = [tex]\frac{1}{3}[/tex] feet
volume of the portion to be covered = area x depth
= 100 x [tex]\frac{1}{3}[/tex]
= 33 [tex]\frac{1}{3}[/tex] cubic feet
The volume of the portion to be covered is 33 [tex]\frac{1}{3}[/tex] cubic feet.
The number of bags of mulch needed = [tex]\frac{33\frac{1}{3} }{2}[/tex]
= 16[tex]\frac{2}{3}[/tex]
= 16.6667
The number of bags of mulch needed is 17.

Latoya made $147 for 7 hours of work.
At the same rate, how much would she make for 9 hours of work?
help pls
Answer:
$189 in 9 hrs
Step-by-step explanation:
Division is one of the four fundamental arithmetic operations. The amount that Latoya will make by working 9 hours is $189.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Latoya made $147 for 7 hours of work. Therefore, we can write,
Money made in an hour = Total Amount / Number of hours
= $147 / 7 hours
= $21 per hour
Now, the amount that Latoya will make in 9 hours will be,
Amount for 9 hours of work = Money made in an hour × Number of hours
= $21 per hour × 9 hours
= $189
Hence, the amount that Latoya will make by working 9 hours is $189.
