The dimensions of a portable kennel can be expressed as width x, length x + 0.4, and height x − 0.2? What are the dimensions of

horsena [70]

Answer:

$L=2.3\ ft\\W=1.9\ ft\\H=1.7\ ft$

Step-by-step explanation:

we know that

The volume of a portable kennel (rectangular prism) is equal to

$V=LWH$

where

$L=(x+0.4)\ ft\\W=x\ ft\\H=(x-0.2)\ ft$

$V=7.4\ ft^3$

substitute the given values in the formula of volume

$7.4=(x+0.4)(x)(x-0.2)$

Apply distributive property right side

$7.4=x(x^2-0.2x+0.4x-0.08)$

$7.4=x(x^2+0.2x-0.08)$

$7.4=x^3+0.2x^2-0.08x$

$x^3+0.2x^2-0.08x-7.4=0$

Solve the cubic equation by graphing

using a graphing tool

The solution is x=1.9

see the attached figure

Find the dimensions

substitute the value of x

$L=(1.9+0.4)=2.3\ ft\\W=1.9\ ft\\H=(1.9-0.2)=1.7\ ft$

Eliminating by multiplying <br> X+3y=1<br> -5x+4y=-24

gavmur [86]

Answer:

y = -1 x = 4

Step-by-step explanation:

(X+3y=1) 5 Multiply this equation by 5 to cancel out the x

-5x+4y=-24

-5x + 4y= -24

+ 5x + 15y = 5 Add both equations together

19y = -19 Divide both sides by 19

y = -1

Plug -1 for y into one of the equations

x + 3(-1) = 1 Multiply 3(-1)

x - 3 = 1

+ 3 + 3 Add 3 to both sides

x = 4

In Walmart parking, there are 175 vehicles parked joe figures out that 64% of the vehicles are white. How many vehicles are NOT

aksik [14]

Answer:

63 vehicles are not white

Step-by-step explanation:

Well you know that there are 175 total vehicles, and that 64% of those vehicles are white. Therefore the remaining percentage of vehicles must not be white.

100%-64%=36%

This means that 36% of the vehicles aren't white.

Now you must find what 36% of 175 is. The word "of" always signals for multiplication, which is exactly what you need to do here. First start by converting the percentage into decimal form:

36%=0.36

Now you can multiply

175 x 0.36 = 63

63 Vehicles are not white
