zzz [600]

Answer:

  • width: 1.9 ft
  • length: 2.3 ft
  • height: 1.7 ft

Step-by-step explanation:

The volume of a rectilinear shape is given by ...

  V = W·L·H . . . . . where W, L, and H represent width, length, and height

Filling in the given information, we want to find a solution to ...

  7.4 = x(x +0.4)(x -0.2)

If we write ...

  f(x) = x(x +0.4)(x -0.2)

Then we're looking for the value of x that satisfies ...

  f(x) -7.4 = 0

The attached graph shows that value to be 1.897, about 1.9 (feet). Then the desired kennel dimensions are ...

  • width: 1.9 ft
  • length: 2.3 ft
  • height: 1.7 ft

To qualify for gold status at awesome airlines, One must fly at least 16500 and less than 31500 miles each year. If Casey takes
SIZIF [17.4K]

Answer:

<em>[22,42]</em>

Step-by-step explanation:

<u>Division </u>

We must find an interval for the number of visits Casey needs to make to her parents to earn the gold status. The lower limit for that status is 16500 miles.

Each round trip flight Casey takes to visit her parents is 750 miles long. To know the minimum number of visits needed, we divide 16500 / 750= 22. To know the maximum number of visits, we divide 31500 / 750 = 42.

Thus, to earn the gold status at awesome airlines, Casey must go between 22 and 42 times to visit her parents. Expressing in interval notation: [22,42]

The average length of a King Cobra is 118 inches, which is 22 inches longer than the black mamba. Write and solve an addition eq
TiliK225 [7]
I think it would be:

22 + x = 118 for your equation.

And then to solve, it would be:

22 + x = 118
-22 -22

x = 96

Average length of black mamba = 96 inches

However it is late where I am so my bad if that’s not what you needed

PLEASE HELP! Will mark brainliest!
Stells [14]

Answer:

x = 4

Step-by-step explanation:

This is special right triangles  

For the triangle on the bottom, the shorter leg is x, the longer leg is x * √3, and the hypotenuse is x *2. This means that the shorter leg is 2 since you the longer leg is that side multiplied by √3. The hypotenuse is x *2, which is 2 * 2 which equals 4.

Now we have one side of the bigger triangle. This triangle is a 45-45-90 triangle, and the rule is that the two legs are x, and the hypotenuse is x *2. Since we found a leg and not the hypotenuse of the bigger triangle, and the two legs are congruent, that means x is 4.

ine segment XY has endpoints X(–10, –1) and Y(5, 15). To find the y-coordinate of the point that divides the directed line segme
stiks02 [169]
X=(-10,-1)=(Xx,Yx)→Xx=-10, Yx=-1
Y=(5,15)=(Xy,Yy)→Xy=5,Yy=15
y=?
ratio=5:3→r=5/3
y=(Yx+rYy) / (1+r)
y=[-1+(5/3)15] / (1+5/3)
y=[-1+(5*15)/3] / [(3+5)/3]
y=(-1+75/3) / (8/3)

y=(24) / (8/3)
y=24*(3/8)
