A wall 15 m long, 30 cm wide and 4 m high is made of bricks, each measuring
22 cm x 12.5 cm x 7.5 cm . If 1/12 of the total volume of the wall consists of mortar, how many
12
bricks are there in the wall
Answers
b= 30cm
h= 4m= 400cm
So, total volume of the wall= l×b×h
= 1500×30×400= 1,80,00,000 cm^3
Now, volume of one brick= 22×12.5×7.5= 2062.5 cm^3
Volume of wall containing only bricks= total volume of the wall - volume of wall containing mortar
= 1,80,00,000 - (1,80,00,000 × 1/12)
= 1,65,00,000 cm^3
So, no. of bricks = volume of wall containing bricks ÷ volume of one brick
= 1,65,00,000 ÷ 2062.5
= 8000 bricks.
Write the equation of the line that passes through the points (9, -2) and (4, 2). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answers
Answer:
The equation of the line that passes through (9,-2)&(4,2) is
y=-4/5x+26/5
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=2-(-2)/4-9
m=4/-5
m=-4/5
y-y=m(x-x¹)
y-2=-4/5(x-4)
y-2=-4/5x+16/5
+2 +2
y=-4/5x+26/5

What is the solutions of the following system of equations.
y = -2x + 2
y = x - 1
Answers
Answer:
x = 1, y = 0
Step-by-step explanation:
Given the 2 equations
y = - 2x + 2 → (1)
y = x - 1 → (2)
Substitute y = x - 1 into (1)
x - 1 = - 2x + 2 ( add 2x to both sides )
3x - 1 = 2 ( add 1 to both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = 1 - 1 = 0
Solution is (1, 0 )

Brainliest? Thanks!Answer:
So the first part of this shape is 400 ft and the secound part of this shape is 544 ft. Hence, since want the whole shape volume your answer would be and always will be 944 ft.
Step-by-step explanation:
since i'm pretty good at math I well tell you how I got this answer in this qustion I seen that this figure is 3-dimensional meaning that we have height,length, and width ( there is two more and were not going to talk about it ) prove we got to time not 2 but 3 times and since this figure has 2 part we would need to brake it into and mutlply both parts (sepertly) to get the answer right so for the first part (or what on the top).
1st part
since the height is 5 ft. that is the first part of our equation,I see that the width must be 10 ft., which well be the second part of our equation, and i see the length is 8 ft so our equation is , 8x10x5 witch mean the first part of the figure is 400 ft
2nd part
since the height is 4 ft. this mean we have the first part of our equation,the width is 8 ft so that the second part of our equation,and I see the length is 17 ft., means this equation is 4x8x17 so this part of the figure is 544 ft.
The whole figure
So with are info from the first and second part of our equation we can now add both parts of the figures means if we add both of them the answer would be 944 ft.
if you don't other stand here a tip:In geometry, a three-dimensional shape can be defined as a solid figure or an object or shape that has three dimensions – length, width and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth.

One week, Ethan earned $391.00 at his job when he worked for 23 hours. If he is paid the same hourly wage, how many hours would he have to work the next week to earn $102.00?
Answers
Answer:
6 hrs.
Step-by-step explanation:
So 391.00 can just be converted to 391 because they mean the same thing, so since we have $391 for 23 hrs, we can divde those, which gives us 17, this answer would show that Ethan earns $17 a hour, so if we divide how much he earns by the hour by how much money he could earn by next week ( 102/17), that would give us 6, Therefore, Ethan would need to work 6 hours for $102.00

The perimeter of the polygon is 12 in. What is the length of side x?
Answers
Answer:
2in
Step-by-step explanation:
Since we are not given the type of polygon, let the polygon be an hexagon. An hexagon is a 6 sides shape. The perimeter of the shape will be the sum of all the sides of the polygon
Perimeter of the polygon = 6L
Length is the length of the side
Given
Perimeter of the polygon = 12in
Substitute and get L
P = 6L
12 = 6L
L = 12/6
L = 2in
Hence the length of side x of the polygon is 2in
