How would I plot and label the numbers 6.5 & 8.5 on a number line to write a inequality using the symbol “>” to compare t

scZoUnD [109]

Answer:

To label 6.5 on a number line, put the plot between the 6 and 7.

Same thing goes for 8.5, except the plot would go between the 8 and 9.

8.5 > 6.5

Step-by-step explanation:

1.) Since 8.5 and 6.5 are decimals, they are not a whole number which is why they go right in the middle of the two numbers they are behind and in front of.

2.) > means greater than, and 6.5 is smaller than 8.5 therefore we use the greater than sign, pointed towards the 8.5.

I hope this helps! :)

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27nft3. Which equation gives the volume o

inna [77]

Answer:

The volume of the sphere is $V=18\pi\ ft^{3}$

Step-by-step explanation:

we know that

The volume of cylinder is equal to

$V=\pi r^{2}h$

we have

$V=27\pi\ ft^{3}$

substitute

$27\pi=\pi r^{2}h$

simplify

$27=r^{2}h$

Remember that

A sphere and a cylinder have the same radius and height

The height of cylinder is equal to the diameter of sphere

h=2r

substitute

$27=r^{2}(2r)$

$13.5=r^{3}$ -----> equation A

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

substitute equation A in the formula of the volume of sphere

$V=\frac{4}{3}\pi (13.5)$

$V=18\pi\ ft^{3}$

Which ordered pairs are in a proportional relationship with (0.2, 0.3)?

MAXImum [283]

Answer:

C and E

Step-by-step explanation:

We are given that

$x_1=0.2,y_1=0.3$

$\frac{y}{x}=\frac{0.3}{0.2}=\frac{3}{2}$

$k=\frac{y}{x}=\frac{3}{2}$

A. $x_2=1.2,y_2=2.3$

$\frac{y_2}{x_2}=\frac{2.3}{1.2}=\frac{23}{12}\neq=\frac{3}{2}$

Hence, it is not in proportional relationship with (0.2,0.3)

B.(2.7,4.3)

$x_3=2.7,y_3=4.3$

$\frac{y_3}{x_3}=\frac{4.3}{2.7}=\frac{43}{27}\neq\frac{3}{2}$

Hence, it is not in proportional relationship with (0.2,0.3).

C.(3.2,4.8)

$x_4=3.2,y_4=4.8$

$\frac{y_4}{x_4}=\frac{4.8}{3.2}=\frac{3}{2}$

Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).

D.(3.5,5.3)

$\frac{y_5}{x_5}=\frac{5.3}{3.5}=\frac{53}{35}\neq \frac{3}{2}$

Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).

E.(5.2,7.8)

$\frac{y_6}{x_6}=\frac{7.8}{5.2}=\frac{3}{2}$

Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).
