2/3 is greater or equal to 7/8

1 answer:

6 0

The smaller denominator will give a larger fraction. Another method for comparing is to think of the fractions. In this example it is obvious that 1/3 is smaller than 7/8. For one thing, 1/3 is smaller than 1/2 and 7/8 is larger than 1/2.

A cone with a radius 2 units is shown below. Its volume is 29 cubic units. Find the height of the cone

rusak2 [61]

Answer:

The height of the cone is $6.9\ units$

Step-by-step explanation:

we know that

The volume of the cone is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the circular base of the cone

h is the height of the cone

In this problem we have

$V=29\ units^{3}$

$r=2\ units$

$B=\pi r^{2}$

substitute the value of r

$B=\pi (2)^{2}=4 \pi\ units^{2}$

<em>Find the height of the cone</em>

$29=\frac{1}{3}(4 \pi)h$

$h=29*3/(4 \pi)$

assume $\pi=3.14$

$h=29*3/(4*3.14)=6.9\ units$

Answer: x = 2/3 and y = 2/3

Step-by-step explanation:

I've attached the solution.

From the solution, you get y = -5x + 4 and

y = x.

Now,

Put y = x in y = -5x + 4.

x = -5x + 4

6x = 4

x = 4/6

x = 2/3

So, y = 2/3 because y = x.
