You have two rectangular prisms (Prism A and Prism B). Prism A has the following dimensions: length x, width y, and height z. Pr

noname [10]

Answer:

Part A) The surface area of prism B is equal to the surface area of prism A multiplied by the scale factor (m) squared

Part B) The Volume of prism B is equal to the Volume of prism A multiplied by the scale factor (m) elevated to the cube

Step-by-step explanation:

Part A) we know that

The scale factor is equal to m

The surface area of the prism is equal to

$S=2B+Ph$

where

B is the area of the base

P is the perimeter of the base

h is the height of the prism

we have

Prism A

$B=xy\ units^{2}$

$P=2(x+y)\ units$

$h=z\ units$

substitute

$SA=[2(xy)+2(x+y)z]\ units^{2}$

Prism B

$B=(mx)(my)=(xy)m^{2}\ units^{2}$

$P=2(mx+my)=2m(x+y)\ units$

$h=mz\ units$

substitute

$SB=[2(xym^{2})+2m(x+y)mz]\ units^{2}$

$SB=[2(xym^{2})+2m^{2}(x+y)z]\ units^{2}$

$SB=m^{2}[2(xy)+2(x+y)z]\ units^{2}$

therefore

The surface area of prism B is equal to the surface area of prism A multiplied by the scale factor (m) squared

Part B) we know that

The volume of the prism is equal to

$V=Bh$

where

B is the area of the base

h is the height of the prism

we have

Prism A

$B=xy\ units^{2}$

$h=z\ units$

substitute

$VA=[(xyz]\ units^{3}$

Prism B

$B=(mx)(my)=(xy)m^{2}\ units^{2}$

$h=mz\ units$

substitute

$VB=[(xym^{2})mz]\ units^{3}$

$VB=[(xyzm^{3})]\ units^{3}$

therefore

The Volume of prism B is equal to the Volume of prism A multiplied by the scale factor (m) elevated to the cube

In a class of 147 students, 95 are taking math(m), 75 are taking science (s), 52 are taking both math and science. What is the p

Dmitriy789 [7]

Subtract 52 from m, s, and the total amount of students.. 52 is the amount of students that would take both math and science. m now equals 43, s now equals 23, and the total students remaining is 95.

Since the criteria wants you to exclude students that take math or science, add m and s together.

$43 + 23 = 66$

This is the total amount of students that take math or science.

To find the probability of picking a student that doesn't take math or science, subtract 66 from the total amount of students.

$95 - 66 = 29$

Take this amount and divide by the total amount of students again.

$\frac{29}{95} = 0.3052$

Convert the decimal into a percentage.

$0.3052 = 30.52$ %

There is a 30.52% chance of picking a student that doesn't take math nor science.
