Answer:

72 in^3

36 in^3

80 in^3

54 in^3

Step-by-step explanation:

Basically, all your doing is multiplying each of the 3 numbers together since the formula for the volume of a rectangular prism is L x W x H.

4 × 3 = 12 × 6 = 72

6 × 3 = 18 × 2 = 36

4 × 5 = 20 × 4 = 80

2 × 9 = 18 × 3 = 54

Hope this helps !! Have a good day! :)

The perimeter of the rectangle below is 84 unit . Find the length side of XY

lesya [120]

Answer:

25 unit

Step-by-step explanation:

See attachment for the missing figure.

Assuming the complete question is:

Side UY = 4z-1

Side UV = 5z+3

Perimeter of rectangle is given by:

2UY+2UV=P

2(4z-1)+2(5z+3)=84

8z-2+10z+6=84

18z+4=84

18z = 84 -4 =>

18z = 80

z= 4.45 unit

Side UV = 5z+3 => 5(4.45) + 3

Side UV ≈ 25 unit

SInce, Side UV = Side XY

Side XY≈ 25 unit

which of these shows the result of using the first equation to substitute for y in the second equation, then combining like term

Furkat [3]

Answer:

C. $\Rightarrow \bold{8x = 16}$

Step-by-step explanation:

Given the two equations:

$y=2x ........ (1)\\ 2x+3y=16.......(2)$

To find:

The correct option when value of y is substituted to 2nd equation using the 1st equation.

Solution:

First of all, let us learn about the substitution method.

Substitution method is the method to provide solutions to two variables when we have two equations and two variables.

In substitution method, we find the value of one variable in terms of the other variable and put this value in the other equation.

Now, the other equation becomes only single variable and then we solve for the variable's value.

Here, we have two equations and value of one varible is:

$y=2x$

Let us put value of y in 2nd equation:

$2x+3y=16\\\Rightarrow 2x + 3(2x) = 16\\\Rightarrow 2x + 6x = 16\\\Rightarrow \bold{8x=16}$

So, the correct answer is option C. $\Rightarrow \bold{8x = 16}$

Help me plssssssss!!!!!!!

ExtremeBDS [4]

Answer:

44 degrees

Step-by-step explanation:

there's two ways u could do this. One is all triangles add up to 180 degrees. u simply ignore the outside angle of 136 degrees, and add 62 and 74, and u get 136. take 180-136, and u get 44.

Another way is all strait angles add up to 180 degrees. take 180-136, and u get 44 degrees

Hope this helps and have a nice day :) :) :)

You travel from City X to City Y. You know that the round-trip distance is 647 miles. City Z, a city you pass on the way, is 27

Nady [450]

Answer:

296.5 miles

Step-by-step explanation:

Round trip distance of City X to City Y is 647 miles.

Round trip includes to and fro.

i.e. City X to City Y and then City Y to City X back.

Let the distance between City X and City Y = D

Distance traveled in round trip between City X and City Y = D + D = 2D

Given than 2D = 647

D = $\frac{647}2$ = 323.5 miles

Kindly refer to the attached diagram, for the location of City Z.

Distance between XY = Distance from X to Z + Distance from Z to Y.

Distance XY = XZ +ZY

323.5 = 27 +ZY

ZY =296.5 miles
