Answer:
Step-by-step explanation:
So Blakes sleep 8 hours per night during the school day
8 hours/night...................................100%
6.5 hours/night...................................?
6.5*100/8=81.25
the change in percentage is 100-81.25=18.75%
the percentage change is 18.75
if it is easier for you, another method is:
8-6.5=1.5 subtract the original amount to the new amount
1.5/8=0.1875 divide by the original amount
0.1875*100=18.75 find the percentage

What does -8/9 × -6/7 really equal
Answer:
16/21
Step-by-step explanation:
The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground. What would be temperature outside plane located at 3 miles above the airport
Answer:
The outside plane located at 3 miles above the airport is of -3.6 degrees.
Step-by-step explanation:
The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground.
This means that the temperature in n miles above ground is given by:
[tex]T(n) = 12 - 5.2n[/tex]
What would be temperature outside plane located at 3 miles above the airport
This is T(3). So
[tex]T(3) = 12 - 5.2*3 = 12 - 15.6 = -3.6[/tex]
The outside plane located at 3 miles above the airport is of -3.6 degrees.

-5x+3y=15 and 2x-3y= -15
Answer:
x = 0; y = 5
Step-by-step explanation:
-5x + 3y = 15
2x - 3y = -15
Add the equations to eliminate y.
3x = 0
x = 0
Now plug in 0 for x in the first equation to solve for y.
-5(0) + 3y = 15
3y = 15
y = 5
Answer: x = 0; y = 5

Janet uses 6.5 pins of white paint and blue paint to paint her bedroom walls. 2/5 of this amount is white paint,and the rest is blue paint.How many pints of blue paint did she use to paint her bedroom walls?
Answer:
3.9 pints
Step-by-step explanation:
Given:
Caroline uses 6.5 pints of blue paint and white paint to paint her bedroom walls.
2/5 of this amount is blue paint, and the rest is white paint.
To find :
How many pints of white paint did she use to paint her bedroom walls?
Solution:
Caroline uses pints of blue paint and white paint = 6.5
Amount of blue paint = 6.5 - 2.6 = 3.9 pints
Therefore, 3.9 pints of white paint she used to paint her bedroom walls.
I need help. Is it possible to do this without graphing?
Answer:
[tex]x=2.3\text{ only }[/tex]
Step-by-step explanation:
We are given the second derivative:
[tex]g^\prime^\prime(x)=0.1x^5-0.29x^4-0.694x^3+1.9136x^2[/tex]
And we want to find the values for -3 < x < 4 in which the graph of g has a point of inflection where the concavity changes from concave up to down.
First, recall that inflection points occur whenever g''(x) = 0 or is undefined.
And that:
g is concave up for an interval if g''(x) > 0 for that interval. g is concave down for an interval if g''(x) < 0 for that interval.Graphing the function (please refer below for the graph), we can see that g''(x) has an inflection point at x = -2.6, 0, 2.3, and 3.2.
If g''(x) changes from concave up to concave down, the values before and after that inflection point must be positive and then negative.
We can see that g''(x) is only positive for the values before the inflection points at x = 0 and x = 2.3.
However, for values after the inflection points, only x = 2.3 becomes negative.
Therefore, since at x = 2.3, the graph changes from positive to negative, this is where the graph of g changes from concave up to concave down.
Notes:
For the point x = 0, the graph stayed positive both before and after x = 0.
Therefore, g does not have an inflection point at x = 0.
