1,4 2,2 = to 2,8 4,4
Step-by-step explanation:
The amount of heat lost by the water is 1870 calories
Step-by-step explanation:
The amount of heat released by a substance is given by the equation

where
Q is the amount of heat lost
m is the mass of the substance
C is the specific heat capacity of the substance
is its change in temperature
In this problem, we have:
m = 85 g is the mass of water
is the specific heat capacity of water
is the change in temperature of the water
Substituting, we find

Answer:
Step-by-step explanation:
Given y=-1/2x-3, rewrite this as y = (-1/2)x - 3 for greater clarity.
x-intercept: Let y = 0 and find x: 0 = (-1/2)x - 3, or
(1/2)x = 3, or x = 6. Thus, (6, 0) is the x-intercept.
y-intercept: Let x = 0 and find y. Then (-1/2)(0) - 3 = y. Thus, y = -3, and the y-intercept is (0, -3).
Plot these two intercepts and then draw a line connecting them.
Example: To graph the y-intercept, start with your pencil point at the origin. Move your pencil point 3 units down and plot a dark dot there.
Both Maria and Edwin get the same price on the end.
$26.50*75%/100=$19.875
$19.875*10%/100+$19.875=$21.86
They are purchased copy of the book for $21.86 each.
Theay have $1.14 after purchasing both.
Answer:

Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Elevated both sides to 1/18
