what is the exact volume of the cylinder

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Answer:

if you have a demos or a school calculator you can put in “ graph and tables “ then you can out in the alone numbers 5,6,7,8 into the left side and on the top put X. Next to that X put Y and put -10 on each, then go to a purple one the answer should be x=2.8 etc. + another number. That should be your answer in X if thats is what its asking.

For the second one it should be the same except you will be using Y.

The correct answer is A :)

Answer:

ced is 110 degrees

Step-by-step explanation:

because ECD is 28 degrees and 28+42=70 and a triange always = 180 degrees so it would have to be 110

The measure of ∠CED is 110 degrees by angle sum property of the triangle.

We are given that line AB is parallel to line CD.

The measure of ∠ABC is 28° and the measure of ∠EDC is 42°

An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.

We know that line AB is parallel to line CD.

So according to alternate interior angles measure of ∠ABC is 28° will be equal to BCD.

Thus, Angle BCD= 28 degrees

Hence, in a triangle CED

∠CED + ∠EDC + BCD = 180

∠CED + 28 + 42 = 180

∠CED = 180 - 70

∠CED = 110 degrees

Therefore, the measure of ∠CED is 110 degrees by angle sum property of the triangle.

Here’s a way To solve :D

if she biked 95 each day, we just find how many days it’ll take.

2912/95=30.65 or 31 days if you want to use 31 I advise you to use 30.65

even though this seems improper, if you multiply 30.65 by 95 you’ll still get 2912

Answer:

∠KDE and ∠CED are adjacent to ∠DEA.

Explanation: Two angles are adjacent if they have a common side and a common vertex.

Option 1: ∠KDE and Option 4: ∠CED

Above answers are correct.

What are Adjacent Angles?

Adjacent angles are those angle which are having a common side and a common vertex. Or we can say that adjacent angles are directly next to each other and do not overlap.

Option 1: ∠KDE

This angle is an adjacent angle to ∠DEA, as they both share a common side that is DE.

Option 2: ∠ICJ

This angle is not an adjacent angles as ∠DEA and ∠ICJ  do not have a common side and a common vertex.

Option 3: ∠GHF

This angle is not an adjacent angles as ∠DEA and ∠GHF do not have a common side and a common vertex.

Option 4: ∠CED

This angle is an adjacent angle to  ∠DEA, as they both share a common vertex that is E and a common side that is DE.

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Answer:

your answer is 0.166 ( it's repeating make sure to have a vinculum that shows 6 is going on for infinity).

Step-by-step explanation:

To convert a fraction to a decimal you have to use division. Fractions can be converted into decimals by division. This method works for converting any fraction to a decimal: You simple have to Divide the numerator by the denominator.

Ex. 2/5 as a decimal would be 0.4

Since you can't divide 5 by 2 you would need to put a 0 down by the 2 making it 20. (btw you can put down as many 0 as needed to get the answer. Say we couldn't get to 20 with 5 you would need to put down another 0 making it 200 but we can so you wouldn't need to do that). Make sure you add the decimal point before the 0. In this case you would write the 0 for 2/5 because that wouldn't work then, you would add the decimal point (.) after the 2 and before the 0 (2.0) but you would write that above it so it would be:

0.

5|20

then you would write the 4:

0.4 because 5 x 4 gets 20.

In this case imagine a box but this box isn't filled in it looks like this \(\sqrt{x}\) so the 1 would be inside and the 6 would be outside the checkmark shape.

Then you would divide

How many times can you go close to or get to 6 without getting to a greater number.

I know this is alot but I think there might be a more simpler version of this somewhere on the internet or something.

If not this is mainly 6th grade math so you might be able to find it on a pdf of 6th math and then you can practice and ask someone if your answers are correct. I don't know that's what I do when I don't really get something the first time.

Answer:

Answer:

Step-by-step explanation:

If the dilated image is smaller than the original, then 0<k<1.

Meaning the scale factor is less than one, but greater than zero.

You would mulitply each coordinate by this scale factor - to obtain the coordinates of the dilated figure.

Let's choose   \(\frac{1}2}\).

In the original figure Point A = (-4,3) dilating by \(\frac{1}{2}\) results in A' being (-2, 1.5).  When you multiply each cooordinate (-4,3) by one half.

Applying the scale factor of one half to the other coordinates - yields these results.

Point B (4,3) becomes Point B' (2, 1.5)

Point C (-4,-4) becomes Point C' (-2,-2).

Point D (4, -4) becomes Point D' (2,-2)

K will equal something more than 0 and less than 1.

i looked it up and found this for u

Step-by-step explanation:

the turtle is initially 20 5/6 inches below the surface.

After which he dives to a depth of 32 1/4 inches

then the initial position below - 20 5/6 inch

final position - 32 1/4 inch

the difference in the positions can be calculated taking the difference between initial and final position

this can be done with a simple subtraction of fractions

difference =

when subtracting mixed fractions the whole numbers are first subtracted

 =  

 =

we can now bring the denominators to a common denominator which is 12

then in the first fraction 1/4, denominator is 4 , to bring it to 12 we can multiply the whole fraction by 3

next fraction 5/6 , denominator is 6, to bring it  to 12 we multiply whole fraction by 2

now since  3/12 is smaller than 10/12 so we borrow a whole number from 12 outside the brackets, then

then

= (12 - 1) ()

 = 11

therefore change in turtles position is 11 5/12 inches
