3y-2(9-2y)=10
3y-18+4y=10
-y-18=10
-y=28
y=-28
3(-28)-2x=10
-84-2x=10
-2x=94
x=-47
so x is -47 and y is -28

Diagram shows the composite solid formed by a cuboid and a right prism. Trapezium LMNP is the uniform cross section of the prism
kherson [118]

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

V = AB\cdot BC\cdot CH\\\\V = 3*6*(3+JY+4)

if you ask where does the 4 come from

it comes from LP = KB = YC and JY + YC =JC

so

V = 18(7+MX)

this is because JY = MX

the other volume is of BCNPKLXY (hope you understand which one)

and the volume is

V = BP*PN*NX\\\\V=8*6*4\\\\V = 192

and the last one is KYXLMJ (the top "triangle")

the volume is

V = \frac{LX*XM}{2}*LK\\\\V = \frac{6*MX}{2}*8\\\\V= 6*4*MX\\\\V=24MX

so now add them up

and has to equal 444

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

and finally we know that MN = MX + XN = 3+4 = 7

so here is our answer MN = 7 cm

a couple of notes

1.\:\angle LXM = 90\\\\2.\:\angle KYX = 90

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

5. tell me if you have questions :D

What is 15 cm/year converted to inches per month? Round to the nearest tenth.
topjm [15]

Answer:

0.5 inches per month

Step-by-step explanation:

There are nearly 0.3937 inches in 1 cm, so

1 \ cm \approx 0.03937 \ in\\ \\15\ cm\approx 5.9055\ in

There are 12 months in the year, so'

15 centimeters per year is equivalent to

15 \ cm/year\approx \dfrac{5.9055}{12}\ in/month\\\approx 0.492125\ in/month\\\approx 0.5\ in/month\\\\

Shayna enlarged a square photo by adding 10 inches to each side so it could be seen on a large poster. The area of the enlarged
ivanzaharov [21]
The area of a square is expressed as the length of the side to the power of two, A = s^2. We were given the area of the enlarged photo which is 256 in^2. Also, it was stated that the length of the enlarged photo is the length of the original photo plus ten inches. So, from these statements we can make an equation to solve for x which represents the length of the original photo.

A = s^2
where s = (x+10)
A = (x+10)^2 = 256
Solving for x,
x= 6 in.

The dimensions of the original photo is 6 x 6.
