Diagram shows the composite solid formed by a cuboid and a right prism. Trapezium LMNP is the uniform cross section of the prism. It is given the volume of the composite solid is 444cm³. Calculate the length, in cm of MN
Answers
Answer:
MN = 7 cm
Step-by-step explanation:
Well the volume we can separate into pieces
first the ABCDEFGH (? you know this cuboid)
which has a volume of
[tex]V = AB\cdot BC\cdot CH\\\\V = 3*6*(3+JY+4)[/tex]
if you ask where does the 4 come from
it comes from LP = KB = YC and JY + YC =JC
so
[tex]V = 18(7+MX)[/tex]
this is because JY = MX
the other volume is of BCNPKLXY (hope you understand which one)
and the volume is
[tex]V = BP*PN*NX\\\\V=8*6*4\\\\V = 192[/tex]
and the last one is KYXLMJ (the top "triangle")
the volume is
[tex]V = \frac{LX*XM}{2}*LK\\\\V = \frac{6*MX}{2}*8\\\\V= 6*4*MX\\\\V=24MX[/tex]
so now add them up
and has to equal 444
[tex]V_T = 18(7+MX)+192+24MX\\\\V_T = 126+18MX+192+24MX\\\\V_T = 318+42MX\\\\444=318+42MX\\\\444-318=42MX\\\\126=42MX\\\\MX = 3[/tex]
and finally we know that MN = MX + XN = 3+4 = 7
so here is our answer MN = 7 cm
a couple of notes
[tex]1.\:\angle LXM = 90\\\\2.\:\angle KYX = 90[/tex]
3. the units don't matter due to the fact that everything is in cm
4. see the picture below to get a better idea of which prism I am talking of

what is 4 to the 7th power
Answers
Answer:
16384
Step-by-step explanation:
The solution for 4 to the 7th power can be expressed as 16,384.
What is 4 to the 7th power?To calculate 4 to the 7th power, we need to multiply 4 by itself seven times. Let's break it down step by step:
4¹ = 4 {4 to the power of 1}
4² = 4 x 4 = 16 {4 to the power of }
4³ = 16 x 4 = 64 {4 to the power of 3}
4⁴ = 64 x 4 = 256 {4 to the power of 4}
4⁵ = 256 x 4 = 1024 {4 to the power of 5}
4⁶ = 1024 x 4 = 4096 {4 to the power of 6}
4⁷ = 4096 x 4 = 16384 {4 to the power of 7}
Therefore, 4 to the 7th power has a solution equal to 16,384.

Answer with only a number, no units: Mohammed runs 3 1/4 miles in 1/2 an hour. What is his rate in miles per hour? *
Answers
Answer:
yes yes
Step-by-step explanation:
Answer: 6 & 1/2
This is a mixed number with 6 as the whole part and 1/2 as the fractional part.
Your teacher may want you to enter the answer without the ampersand symbol. If that's the case, then you would type in 6 1/2.
=============================================================
Work Shown:
1/4 = 0.25
3 & 1/4 = 3 + 1/4 = 3 + 0.25 = 3.25
1/2 = 0.5
He runs 3.25 miles in 0.5 of an hour
d = distance = 3.25 miles
t = time = 0.5 hour
r = unknown rate or speed in miles per hour (mph)
------------
distance = rate*time
d = r*t
3.25 = r*0.5
3.25 = 0.5r
0.5r = 3.25
r = 3.25/0.5 .......... divide both sides by 0.5
r = 6.5
r = 6 + 0.5
r = 6 + 1/2
r = 6 & 1/2
His rate is 6 & 1/2 mph
