A right rectangular pyramid when sliced vertically, the shape of the cross-section is known as Triangle.

<h3>What is A triangle?</h3>

This is known to be a kind of shape that is said to be in a closed form and it is also known to be a 2-dimensional shape that has 3 sides, 3 angles, and also 3 vertices.

Note that when the when the right rectangular pyramid is sliced vertically (down) by a plane passing through the of the pyramid, the new shape of the cross-section is a triangle.

musickatia [10]

Answer:

The patient owe $1255.6 .

Step-by-step explanation:

As given

A patient's total surgery charges are $1,278.

The patient must pay the annual deductible of $1,000.

The policy states a 80-20 coinsurance. (i.e 20% of the surgery amount is given by the patient .)

20% is written in the decimal form .

$= \frac{20}{100}$

= 0.20

20% of patients surgery cost = 0.20 × $1278

= $ 255.6

Patients owe = Deductible cost + 20% of patients surgery cost

= $1000 + $255.6

= $ 1255.6

Therefore the patient owe $1255.6 .

George has $49 which he decides to spend on x and y. commodity x costs $5 per unit and commodity y costs $11 per unit. he has th

FromTheMoon [43]

We are given the equations:

Rewrite eqtn 1 explicit to y:

11 y = 49 – 5 x

Substitute eqtn 3 to eqtn 2:

u = 3 x^2 + 6 [(49 – 5x) / 11]^2

u = 3 x^2 + 6 [(2401 – 490 x + 25 x^2) / 121]

u = 3 x^2 + 14406/121 – 2940x/121 + 150x^2/121

u = 4.24 x^2 – 24.3 x + 119.06

Derive then set du/dx = 0 to get the maxima:

du/dx = 8.48 x – 24.3 = 0

solving for x:

8.48 x = 24.3

x = 2.87

so y is:

y = (49 – 5x) / 11 = (49 – 5*2.87) / 11

y = 3.15

Answer:

<span>George will choose some of each commodity but more y than x.</span>

Combine like terms and simplify 4r - 6 - 2r + 5

murzikaleks [220]

C. 10r-3

Because 2r+5=7, the minus 6 and 7 which gives you 1 then minus 4 and 1 witch is 3 then you do 10r-3 and it will get you to 2r+5=7 again. I hope this helped!
