Step-by-step explanation:
20 + 20 + 20 +20 + 20 + 20 + 20 + 20 +20 = 180
45 + 45 + 45 + 45 = 180
Bus A would've taken 9 routes and Bus B would've taken 4, to reach the bus depot together
180 mins - hours = 3 hours
6 + 3 = 9

Answer:
1. x = -4
y = -20
2. x = -1
y = 3
3. x = 7
y = 4
4. x = -6.5
y = -10.5
hope this helps :) sorry if I get it wrong!
Answer:
1) x=−4, y=−20
2) x=−1, y=3
3) x = 7 , y=4
4) x = -6.5 , y = -10.5
Step-by-step explanation:
1) y=5x;−3x+2y=−28
solving system by substitution:
substitute y =5x into 2nd equation:
-3x +2*5x =-28 → -3x+10x = -28 → 7x = -28 → x = -4
plug in x in any equation and solve for y = 5* -4 = -20
2) solving system by elimination:
Multiply the first equation by 7, and the second equation by 5.
7(4x−5y=−19)
5(3x+7y=18)
----------------------
28x−35y=−133
15x+ 35y= 90
Add them up to eliminate y:
43x=−43 divide both sides by 43
x=−1
plug x back into 1st equation to solve for y
4x−5y=−19
(4)(−1)−5y=−19
−5y−4=−19 add 4 to both sides
−5y=−15 divide by -5
y=3
3) y =4 , 5x -6y = 11
plug in 4 for y in 2nd equation and solve for x:
5x -6* 4 =11 simplify
5x - 24 = 11 add 24 on each side
5x = 11 +24 simplify
5x = 35 divide by 5 on each side
x =7
4) y = x -4, 2x - y = -2.5
use substitution method:
2x -(x-4) = -2.5 distribute ( )
2x-x+4 = -2.5 simplify
x + 4 = -2.5 subtract 4 on each side
x = -2.5 -4
x = -6.5
plug in -6.5 for x in 1st equation and solve for y:
y = -6.5 -4
y = -10.5

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).
Answer:
The area of the shaded area is 27 [tex]\pi[/tex]
Step-by-step explanation:
The formula for the area of a circle is :[tex]\pi *radius^2[/tex]
To work this out you would first have to work out the area of the circle. You can do this by multiplying [tex]\pi[/tex] by the radius of 6 squared, this gives you 36[tex]\pi[/tex]. However the question is asking for that section of the circle.
To work out the area of the shaded section you will first have to look at the missing angle, as it is 90° . A circle has 360° and so if we divide 360 by 90, this gives us 4. This tells us that [tex]\frac{3}{4}[/tex] of the circle is shaded as [tex]\frac{1}{4}[/tex] is not.
To work out the area of the shaded area you would divide the area of the whole circle which is 36[tex]\pi[/tex] by 4, this gives us 9[tex]\pi[/tex]. This tells us the area of 1 quadrant of the circle.
The next strep is to multiply 9[tex]\pi[/tex] by 3, this gives us 27[tex]\pi[/tex]. This is because now that we know the area of one quadrant we can find the area of the shaded area which covers 3 quadrant of the circle.
1) Multiply [tex]\pi[/tex] by 6 squared.
[tex]\pi *6^2=36\pi[/tex]
2) Divide 360 by 90.
[tex]360/90=4[/tex]
3) Divide 36 [tex]\pi[/tex] by 4.
[tex]36\pi/4=9\pi[/tex]
4) Multiply 9 [tex]\pi[/tex] by 3.
[tex]9\pi*3=27\pi[/tex]

12. For angle A it is known that sin(A)>0 and tan (A) <0. If A is drawn in standard position, in which quadrant
does its terminal ray lie?
Answer:
Quadrant 2
Step-by-step explanation:
Sin = opp/hyp and opp is positive in quadrants 1 & 2.
Tan = opp/adj - we need one of these values to be positive and the other negative. adj is negative in quadrants 2 & 3.
Quadrant 2 is found in both of the scenarios that we need to occur.

A box is designed to hold pencils. The front of the box will be made from a clear material for display. The rest of the box will be made from cardboard.
A prism has a length of 20 centimeters, height of 5 centimeters, and width of 4 centimeters.
What is the surface area of the side with the clear material?
Answer:
area of a rectangle/front side of the box = 100 cm²
Step-by-step explanation:
The prism box is a rectangular prism and the front side of the box will be made of the clear material. The other sides will be made of cardboard paper. The surface area of the side with clear material is only the area of the front side of the box. The area of only the front side is the area of 1 rectangle.
The box has a length of 20 cm , height of 5 cm and a width of 4 cm. The surface area of only the front side of the box which is the area of one rectangle only deals with the height and the length.
area of a rectangle/front side = length × height
where
length = 20 cm
height = 5 cm
area of a rectangle/front side = 20 × 5
area of a rectangle/front side = 100 cm²

A square pyramid and its net are shown below. What is the surface area of the pyramid?
Answer:
736 Maybe
Step-by-step explanation:
Well what you gotta do is the triangles on the sides can be moved to form mini rectangles. When you do this you get 8 by 15 rectangles and since you have 4 of then you multiply those by 4. 8*15= 120 and 120*4 = 480. Then all you need to fing is the center square pretty easy to find that square right. Its just 16*16 = 256. And 480+256=736.
I hope this helps.
The surface area of the square base pyramid is 736 cm².
Surface area = A + 1 / 2 ps
where
A = base area
p = perimeter of the base
s = slant height
Therefore,
A = 16² = 256 cm²
p = 4(16) = 64 cm
s = 15 cm
surface area = 256 + 1 / 2 × 64 × 15
surface area = 256 + 480
surface area = 736 cm²

D. Costs of $4000 and revenues of $5000
Answer: C. Costs of $4000 and revenues of $4000
Step-by-step explanation: took the quiz.
The break-even point for a given company can be Costs of $4000 and revenues of $4000
What is a break-even point?The break-even point is the point at which total cost and total revenue are equal, meaning there is no loss or gain for your small business.
Given are some options we need to find a condition for a company to have a break-even point
Since, the break-even point is a condition of no loss no gain, that the difference of the cost and revenue is zero, that stage is called a break-even point.
From the options, option C is showing a condition of neither gain nor loss, it's having both cost and the revenue same = $4000
Hence, the break-even point for a given company can be Costs of $4000 and revenues of $4000

A company is trying to calculate the amount of
concrete that will be needed to create one concrete
block that is in the form below.
The concrete block is a rectangular prism with two
cubes cut out. The cubes have a side length of 6
inches.
What is the total volume, cubic feet, of concrete
needed to make this block?
Answer:
[tex]0.19\,\,cubic\,\,feet[/tex]
Step-by-step explanation:
Given:
The concrete block is a rectangular prism with two cubes cut out. The cubes have a side length of 6 inches.
To find: total volume, cubic feet, of concrete needed to make this block
Solution:
Side of cube = 6 inches
Volume of cube = [tex](side)^3=6^3=216\,\,cubic\,\,inches[/tex]
So, volume of two cubes = 2(216) = 432 cubic inches
Length of rectangular prism = 12 inches
Breadth of rectangular prism = 8 inches
Height of rectangular prism = 8 inches
Volume of rectangular prism = length × breadth × height = [tex]12(8)(8)=768 \,\,cubic\,\, inches[/tex]
Total volume of concrete needed to make this block = Volume of rectangular prism - Volume of two cubes = 768 - 432 = 336 cubic inches = [tex]\frac{336}{1728} =0.19\,\,cubic\,\,feet[/tex]
( use 1 cubic inch = [tex]\frac{1}{1728} \,\,feet[/tex])

What is the missing leg length
Answer:
b = 16
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2 + b^2 = 20^2
144+b^2 = 400
Subtract 144 from each side
b^2 = 400-144
b^2 = 256
Take the square root of each side
sqrt(b^2) = sqrt(256)
b = 16
