Greg needs to practice his clarinet for 40 minutes per day. He already practiced 30% of the total time needed. How many more minutes does he need to practice?
Simplify each expression using exponents.
Step-by-step explanation:
1. 5^2*5^6
=5^(2+6)
=5^8
2. e^2*e^7
= e^(2+7)
= e^9
3. 2a^5*6a
= 12a^6
4. 4x^2*(-5x^6
= -20x^8

I need help plz
I will give points
Answer:
D
Step-by-step explanation:
865 x 1.25
bc 0.25=25%
25%+100%= 125% =1.25
or
865 x 0.25= 216.25
216.25 +865= 1081.25
1081.25/865=1.25
What number should be added to both sides of the following equation to solve for g?
g - 18 1/3 = 25
Add 9 to both sides of the equation.
Subtract 9 from both sides of the equation.
Subtract 13 from both sides of the equation.
Add 9 to the left side of the equation.
Answer:
43 1/3
Step-by-step explanation: Not sure what that second part it but for that equation it is 43 1/3 because you need to isolate the variable by adding the 18 1/3 to the 25 and whatever that equals is your answer so I added
g-18 1/3=25
18 1/3+25
g= 43 1/3
^ see it says g= ___ and that is what g equals

<-- 20 points No Trolls please
Answer: 9
Step-by-step explanation:
The reason for this is because the top row is 1234 you have to take the 27 and divide it by 3 giving you 9 so that means that the ? equals 9
Please help ASAP. Please show work if you can . Thank you!
Answer:
C = 2 π r
Step-by-step explanation:
Your answer is 2 pi/π r.
The formula of a circumference is always 2 pi r.
18 x 3.14 x 2 = 113.04
in this case radius is 18
pi is 3.14
2 is just always there when finding out circumference.
Answer:
113.04 (estimated)
Step-by-step explanation:
I used the formula that includes pi.
basically multiply the radius by 2 and multiply the answer with π or 3.14 for the estimation.

PLEASE HELP PROBLEM IN PHOTO!
Answer: Should be 130
Step-by-step explanation:
A is 80 180-80 is 100. Since it’s an isosceles you can divide by 2 and the two angles would be the same. 100/2 is 50 because two remote interior angles is equal to the exterior angle, 50+80 is 130, d is 130
Answer:
Angle D is 130 degrees
Step-by-step explanation:
180-80=50
Angles b and c are the same and will both be 50 degrees.
The angle of a straight line is 180 degrees.
Since angle c is 50 degrees, then the other angle (d) will have to be 130, so that together the total of the two is 180 degrees.
I hope this helps :)

The box plot below shows the total amount of time, in minutes, the students of a class surf the Internet every day:
A box plot is shown. The left-most point on the plot is 20 and the right-most point is 95. The box is labeled 40 on the left edge and 60 on the right edge. A vertical line is drawn inside the rectangle at the point 50.
Part A: List two pieces of information that are provided by the graph and one piece of information that is not provided by the graph.
Part B: Calculate the interquartile range of the data, and explain in a sentence or two what it represents.
Part C: Explain what affect, if any, there will be if an outlier is present.
Answer:
This is for A Part A: it shows that the least amount is 37.5 minutes
it shows the most amount of time is 60 minutes
one thing it does not show is how many students were in the class

Please Help me
Answer:
3063
Step-by-step explanation:
;D B
picture of question below
Answer:
99
Step-by-step explanation:
area of a triangle formula = [tex]\frac{bh}{2}[/tex]
where b = base length and h = height
The triangle shown has a base length of 11 and a height of 18
Using this information we plug in the values into the formula
[tex]A=\frac{11*18}{2} \\11*18=198\\\frac{198}{2} =99[/tex]
Hence the area of the triangle is 99ft²
The sum of three numbers is 254.772. We can get the biggest and smallest numbers if we move the decimal point in the middle number two digits to the right and one digit to the left, respectively. What is the middle number?
A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.
Write the equivalent expression ("simplified") that represents the total volume of the water in the pool in ft3.
Answer:
The total volume of water in the pool = ( 6x^3 + 12x^2 - 90x ) ft^3
Step-by-step explanation:
The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3
The volume of water in the shallow = (4x^3 -100x) ft^3
The total volume of water in the pool = (2x^3 + 12x2 + 10x) + 4x^3 -100x)
= ( 6x^3 + 12x^2 - 90x ) ft^3
