For this case the first thing you should know is the following unit conversion.
 1 BTU = 0.25 Kilocalories
 We then have the following numerical value:
 8.0 * 10 ^ 4 \frac{BTU}{h}
 Applying the conversion of units we have:
 8.0 * 10 ^ 4 \frac{BTU}{h} * 0.25 \frac{Kcal}{BTU}
 Canceling units we have:
 20000 \frac{Kcal}{h}
 Answer:
 
This is 20000 kilocalories per hour
 
20000 \frac{Kcal}{h}

Which situation could be modeled by the expression 13÷5 ?
Alex

Answer: The expression 13÷5 is a fraction. Here the only option that makes sense as per this expression is:

B. Each of 5 cupcakes used 13 pound of sugar. What is the total amount of sugar used?

Therefore the option B is correct

Also please note:

A fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole.

Answer:

C. $15,500

Step-by-step explanation:

The rate of change of the x values is 2

The rate of change of the y values is 1.

To continue this pattern:

x   38    40     42     44     46

y   12     13      14       15     16

If x = 45, y = $15,500

Please solve with explanation
yan [13]

Answer:

The x coordinate of S is b.

Step-by-step explanation:

a)

The coordinates of Point Q are:

(2a+2b)/2, 2c/2

= [(a + b), c].

The slope of the line AB

= (0-2c)/(2b-2a)

= -c/(b-a)

So The slope of the line QS = (b - a) / c = (b - a)/c.

Its equation is

y - c = (b - a)/c ( x - (a+b))

y = (b - a)/c ( x - (a+b)) + c.

The coordinates of Point P are:

(2a+0)/2, 2(c+ 0)/2

= (a, c)

The slope of the line AO

= (2c)/2a

= c/a

So The slope of the line PS = -a/c

Its equation is

y - c =  -a/c(x - a)

y  =  -a/c(x - a) + c

b)

So:

(b - a)/c ( x - (a+b)) + c

=  -a/c(x - a) + c

(b - a)(x - a - b) + c^2 = -a(x - a) + c^2

(b - a)(x - a - b) = -a(x - a)

bx - ab - b^2  - ax + a^2 + ab = -ax + a^2

bx - ax + ax + a^2 - a^2 - ab + ab = b^2

bx  =  b^2

x = b = the x coordinate of S.

c). The point R has the same x coordinate as S So RS is perpendicular to OB.
