Please help me it’s urgent! I WILL MARK AS BRANLIEST!

Mathematics
1 answer:
UkoKoshka [18]3 years ago
3 0

Answer:

(1,4)

Step-by-step explanation:

2x-3y=-10

y=4x

Since the y is already isolated, you can use substitution to find the answer to this equation. Simply replace any y values in the first equation with 4x:

2x-3(4x)=-10

2x-12x=-10

-10x=-10

x=1

y=4(1)=4

Hope this helps!

Hello hello :))) please help me with this problem
Vsevolod [243]
Since they want the unit of volume to be cm^3, first we have to convert the values given from inch into cm
=> 12 in = 30.48cm
4 in = 10.16cm
14 in = 35.56cm
Since both of the figures are cylinders, we have to find them one by one
Find the volume of the upper cylinder
Formula: V = pi*r^2*h
We know, pi = 3,
radius = diameter of base/2
=> r = 30.48cm/2 = 15.24cm
height = 30.48cm
We get V=3*(15.24)^2*30.48=21237.6cm^3

Find the volume of lower cylinder
Formula: V = pi*r^2*h
We know, pi = 3,
radius = diameter of base/2
=> r = 35.56cm/2 = 17.78cm
height = 10.16cm
We get
V = 3*(17.78)^2*10.16 = 9635.6cm^3
Therefore, the volume of the object is
V = 21237.6cm^3 + 9635.6cm^3
= 30873.2cm^3.
