PLS HELP I WILL MARK BRAINLIST

It’s d

Because…
A= 77% which is equivalent to .77, which is less than 1

B= 10/8 because it is a little more than one

And by looking at the line you can see how C and D are marked correctly because both of them are over 2, and D is a little bigger than C

A rectangular prism and a cylinder have the same height. The length of each side of the prism base is equal to the diameter of t

NARA [144]

Answer:

The rectangular prism has the greater volume

Step-by-step explanation:

Given

Prism:

$Length = Width = a$

$Height = h$

Cylinder

$Diameter = a$

$Height = h$

Required

Shape with greater volume

The volume of a rectangular prism is:

$Volume = Length * Base * Height$

So, we have:

$V_1 = a*a*h$

$V_1 = a^2h$

The volume of a cylinder is:

$Volume = \pi r^2h$

Where

$r = \frac{d}{2}$

$r = \frac{a}{2}$

So, we have:

$V_2 = \pi *(a/2)^2 h$

$V_2 = \pi *\frac{a^2}{4} h$

$\pi = 3.14$

So:

$V_2 = 3.14*\frac{a^2}{4} h$

$V_2 = \frac{3.14}{4} a^2h$

$V_2 = 0.785 a^2h$

So, we have:

$V_1 = a^2h$

$V_2 = 0.785 a^2h$

Both expressions have the same factor but different coefficient

The expression with greater coefficient has the greater volume

So, the $rectangular$ $prism \\$ has the $greater$ $volume$

Because: $1 > 0.785$

A stone fell from the top of a cliff into the ocean.

Nikitich [7]

Answer:

5 seconds.

Step-by-step explanation:

Make an equation.

Time in air = x

Time in water = 12 - x

16x + 36 - 3x = 127

13x = 91

x = 7

12 - 7 = 5

Solve the equation 2(AB) + 16 = 24 to find the length of segment AB. Write a justification for each step.

Lera25 [3.4K]

2(AB)+ 16= 24
⇒ 2(AB)= 24 -16
⇒ 2(AB)= 8
⇒ AB= 8/2
⇒ AB= 4

Final answer: AB=4~
