The answer is 280 because you multiply 7cm x 2cm , then 2cm x 14cm, then you multiply is 14cm x 7cm . Then 7x2=14 , 2x14=18 ,then 14x7=98. So multiply 28,96, and 14 by 2 to get 196 ,56, and 28. Then your total will come up to 280
A line that's perpendicular would have a slope that the negative reciprocal of the line in the question
1. use the points to find the slope
(y1-y2)/(x1-x2)
=(-3-7)/(-7+5) (it's +5 because --5=+5)
=-10/-2
-5
slope of the line is -5
2. The negative reciprocal is basically flipping over a fraction (3/4 would become 4/3) and then multiplying it by -1 (4/3 would become -4/3)
Because -5 is really -5/1 you would flip it to -1/5 then multiple by -1 to equal 1/5.
3. Now we just need any line that has a slope of 1/5
y=mx+b where m=1/5 and b is whatever number you want
y=1/5x+8
y=1/5x-193748
y=1/5x-103595
All these are right answers just pick your favourite number for b
Answer:
Step-by-step explanation:
Find the magnitude of the complex number
Notice the magnitude is equal to
where a is the real number and b is the imaginary number.
Substitute
Multiply this by -5
Answer:
The volume of one shaped-cube block is
Step-by-step explanation:
we know that
The volume of a cube is equal to
where
b is the length side of the cube
step 1
Find the length side of one shaped-cube block
Let
x------> the length side of one shaped-cube block
y-----> the length side of the storage container
-----> equation A
we have
---> convert to an improper fraction
substitute in the equation A
step 2
Find the volume of one shaped-cube block
