Answer:
Part 1) When the amount of calling is 450 minutes the two plans cost the same
Part 2) When the two plans cost the same , the cost is $68.50
Step-by-step explanation:
Part 1) For what amount of calling do the two plans cost the same?
Let
x ---> the number of minutes
y ----> the total cost
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
Plan A
The slope is equal to
The y-intercept is
substitute
----> equation A
Plan B
The slope is equal to
The y-intercept is
substitute
----> equation B
Equate equation A and equation B
solve for x
therefore
When the amount of calling is 450 minutes the two plans cost the same
Part 2) What is the cost when the two plans cost the same?
substitute the value of x=450 minutes in equation A or equation B and solve for y
therefore
When the two plans cost the same , the cost is $68.50
Answer:
5.66
Step-by-step explanation:
The Square Root of 8 = 2.82842712475.
So, now we times it by two.
2 * 2.82842712475 = 5.65685424949
So, if you round it to the nearest hundredth it's 5.66.

Hey there!
The answers would be
A. reproduction
B. temperature regulation
C. oxygen transportation
D. heat absorption
E. nutrient reproduction or ALL OF THE ABOVE
Water keeps all of your organs and cells functioning properly including the reproductive cells (egg, sperm) and reproductive organs (brain, ovaries, uterus, testes, thyroid). It also naturally flushes out toxins in the body. For men, semen production and semen volume can be reduced by not drinking enough water.
Water is intricately involved in numerous functions of the body including the transport of oxygen, nutrients and waste products into and out of the cells.
Water has a high heat capacity (an ability to absorb heat) because for water to increase in temperature, water molecules must be made to move faster within the water; doing this requires breaking hydrogen bonds (the H2 in H2O) and the breaking of hydrogen bonds absorbs heat.
Living organisms need water to survive. Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.
Hope this helps!
