The answer is -3.7. Plug in -2.5 into the expression. Then the expression is rewritten as 2.2 - 2.5 - 3.4.  Subtract -2.5 from 2.2 and you get -.3. Now, the expression is -.3 - 3.4. Subtract those from each other and you get -3.7.

The volume of a spherical tank is 790.272 pie cubic feet what is the diameter of the container
pochemuha

Answer:

The diameter is 13.88 feet.

Step-by-step explanation:

1. The formula for calculate the volume of a sphere is:

V=\frac{3}{4}(r^{3}\pi)

Where r is the radius.

2. The diameter is:

D=2r

3. So, you must solve for the radius in the first equation:

r=\sqrt[3]{\frac{4V}{3\pi}} 

r=\sqrt[3]{\frac{4(790.272ft^{3} )}{3\pi}}\\r=6.94ft

4. Then, the diameter is:

D=2(6.94ft)\\D=13.88ft

Please help me with this Geometry Proof ASAP - IMAGE ATTACHED - THANKS
blondinia [14]

1) in first place you need to Know what kind of figure is it, in order to find solve the problem, as you can see it is a parallelogram, and the condition for this geometric figure the opposites  are equal ,

2) if you have a non -rectangular parallelogram and draw a diagonal  from A to C, you obtain two equal triangles, for this reason the line AC IS CALLED DIAGONAL,  and divide the parallelogram

3) in first place to determine that the angles are congruents for two triangles the Diagonal is comun for both, and the vertex  ∡CAB IS THE SAME ∡ACD

4) If the diagonal AB AND CD are equal , AD AND BC are equal too, then the triangles are congruent

5)  segment AB Parallel to CD THEY HAVE THE SAME SLOPE AND MAGNITUDE

Which of the following is a polynomial with roots: − square root of 5 , square root of 5 , and −3?
tresset_1 [31]
Roots: - √5 , √5, and - 3

=> these are factors of the polynomial: (x + √5), (x - √5), and (x + 3).

Multiply those three factors:

(x + √5) (x - √5) ( x + 3) = [x^2 - 5] ( x + 3 ) = x^2 + 3x^2 - 5x - 15

Therefore the polynomial x^2 + 3x^2 - 5x - 15 is a polynomial with the given roots.

Answer: option B. x^3 + 3x^2 - 5x - 15

Question 1 of
AnnyKZ [126]

Answer:

5L/2 < 100

Step-by-step explanation:

Let's get started!

Let :

⇒ Length = L

⇒ Width = L/4

It mentions the perimeter must be less than 100 inches.

Perimeter Formula :

<u><em>Perimeter (Rectangle) = 2(Length + Width)</em></u>

Then, the inequality formed will be :

⇒ 2 (L + L/4) < 100

⇒ 2 (5L/4) < 100

⇒ 10L/4 < 100

⇒ 5L/2 < 100
