Shannon graphed the system of equations.
7x – 4y= –8
y = y equals StartFraction 3 over 4 EndFraction x minus 3.x – 3
A coordinate grid with 2 lines. The first line passes through (0, negative 3) and (negative 4, negative 6). The second line passes through (0, negative 2) and (negative 4, negative 6). The lines appear to cross at about negative 5 and between negative 6 and negative 8.
What is the closest approximate solution to the system of equations?
Given number => 1104
Nearest square number => 1156
1156 - 1104 = 52
52 should be added to 1104 to get a perfect square number .
Square root of 1156 = 34
answer:volume of the ball: 1000 c-cmradius of the ball:
Would the surface of the water be 4cm below the top of the tank?
A glass tank is 25cm long, 20cm wide, 30cm high and contains water. The surface of the water is 5 cm below the top of the tank.
Water tank is in the shape of cuboid:
Volume of cuboid:
After a solid metal spherical ball B1 has carefully been placed into the tank, the surface of the water is 3cm below the top of the tank.
Change in height of water level after placing the spherical ball in it = 2 cm
Volume of water raised = Volume of spherical Ball
10.1) Calculate the volume of the ball
10.2) Calculate the radius of the ball. Leave your answer in terms of and a surd if necessary.
10.3) Suppose the radius of a second solid metal ball, B2; is half the radius of ball B1: Suppose ball B2 was put into the tank of water instead of ball B1: Would the surface of the water be 4cm below the top of the tank? Explain your answer
answer: B2 is half the radius of B1
On putting that ball let the change in height of water is h,so
No,the surface of water is 4.75 cm below.
Hope it helps you.
your mad why? why? why?
let the common ratio be x
so the copper=4x and
total mass of alloy=413g
according to question
so the copper = 4×59=236
and the zinc=3×59=177
