Beccas dad told her that she needs to practice piano for two hours this week so far she has practiced 20 minutes on Monday a half an hour on Tuesday and 15 minutes on Wednesday how much longer does she need to practice?
Answers
Answer:
Step-by-step explanation:
She needs to practice piano for 2 hours this week:
Lets add the time she played the piano so far:
Monday + Tuesday + Wednesday
Which is
20 + 30 (half an hour) + 15
= 65 minutes
In which 2 hours is equal to 120 minutes
So,
120 - 65 = 55
She needs to practice for 55 more minutes in this week

You have the diameter which is 2 times to radius. In order to get the radius you half the diameter which is 9.
9 to the second power is 81. Then you multiply it by the height which is 11. 81 x 11 is 891. So 891 x pi would be about 2799.16.
2r=d 2 r = d.
So plug in 18m in as d.
2r=18
/2 /2
r= 9
The volume of a cylinder is v= πr^2h
Use Pi symbol in calculator unless specified to use 3.14
The height is 11m
V=πr^2h
V= π(9)^2(11)
V= π(81)(11)
V= π(891)
V= 2,799.159054348506
So, to the nearest whole number: v= 2,800 m

Answers
Answer: 36 inches (in.)
Step-by-step explanation:
The first thing you need to do is form a right triangle from the starting point to the hole to the corner where the ball is at. Right triangles have a hypotenuse (the longest side), and two legs (the shorter sides).
We are told next to the drawing that it’s 39 feet from the staring point to the hole (given a straight line). This is the length of our hypotenuse. We are also given the length of one of the legs, with it being 36 feet.
We need to find the length of the last leg, the length from the ball to the hole. To do this, we can use the Pythagorean Theorem. The Pythagorean Theorem states that the square of each of the legs equals the square of the hypotenuse. The formula for the Pythagorean Theorem is \(a^{2} +b^{2} =c^{2}\), with \(a\) and \(b\) being the legs, and \(c\) representing the hypotenuse.
Input the given values into the formula and you get the following:
\(a^{2} +b^{2} =c^{2}\)
\(36^{2} + x^{2} =39^{2}\)
\(\sqrt{36^{2} } +\sqrt{x^2} =\sqrt{39^2}\)
\(36 +x =39\)
\(x=3\)
Therefore, the length from the ball to the hole is 3 feet (ft.).
BUT WAIT
The question asks us to provide our answer in inches (in.), and 1 foot equals 12 inches.
Therefore, the distance from the ball to the hole is 36 inches (in.).

A rational number is a number that can be represented as a/b where a and b are integers and b is not equal to 0.
Since -0.8 is an integer or decimal from above, -0.8 is also a rational
An irrational number is a number that cannot be expressed as a ratio between two integers and is not an imaginary number.

Answers
Answer: It is below with explanations on how to do it! :D
Step-by-step explanation:
1. First one shows a graph and a line. Remember, the equation for this is y = mx + b. The point that crosses the y-axis is 0. So far, the equation looks like this: y = mx + 0. In order to find the slope, we have to choose another point on the graph. I will choose the point (-4, -2). The slope is the direction of the line travelling from left to right. So to get from (-4, -2) to the point 0, aka origin, we have to go up 2 units and move 4 units to the right. This method is called rise over run. Now the slope is 2 over 4 -> 2/4.
Final answer is y = 2/4x + 0
Simplified version is y = 1/2x + 0
That is your equation in slope intercept form!
2. The second one shows a graph and is asking to write an equation in slope-intercept form. Here is the equation for that -> y = mx+b
M is the slope, and b is the y-intercept (where the point crosses the line on the y-axis).
So, in this case, M=4 and b=0
Plug it into the equation, y = 4x + 0
The graph is attached below (I did not draw it but I took a screenshot from a video that shows it)
I also attached the graph for you for the last question!

A sporting goods store is having a sale in which all sleeping bags are discounted by 20%. Priya has a coupon for $5 off the regular price of a sleeping bag. The store first applies this coupon and then takes 20% off the reduced price. If Priya pays $34.40 for the sleeping bag, what was the original price, x, before the sale and without the coupon?
Answers
the original price was "x", which oddly enough is the 100%.
now, let's pluck out of "x" 5 bucks, so that makes it "x-5", that's our new adjusted 100%, from which the lady at the counter is happy to apply a 20% discount. Now, if the lady discounts 20% off of that "x-5" amount, what Priya is really paying for the sleeping bag is just 100% - 20% = 80%, and we happen to know that that 80% was really $34.40.
now, if "x - 5" is the 100%, and we know that 34.40 is the 80%, what the heck is "x"?
\(\begin{array}{ccll} amount&\%\\ \cline{1-2} x-5 & 100\\ 34.40& 80 \end{array} \implies \cfrac{x-5}{34.40}~~=~~\cfrac{100}{80} \implies \cfrac{ x-5 }{ 34.40 } ~~=~~ \cfrac{ 5 }{ 4 } \\\\\\ 4x-20=172\implies 4x=192\implies x=\cfrac{192}{4}\implies x=48\)

Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

I hope I helped you !!
Have a good evening !!!
Patrick can form a triangle using the rod lengths of 20 inches and 27 inches and 47 inches. The other combinations of rod lengths do not meet the conditions laid out by the triangle inequality theorem.
Explanation:The subject of this question is Mathematics, specifically focusing on geometric properties of triangles. According to the triangle inequality theorem, a triangle can only form if the sum of the lengths of the two shorter sides is greater than the length of the longest side. In this context, Patrick uses scrap metal to build sculptures and wants to create triangles from metal rods which are 20 inches, 27 inches, 47 inches, and 67 inches long. Using the triangle inequality theorem, we can determine which combinations of rod lengths can form a triangle:
If he uses the rod lengths 20 inches, 27 inches, and 47 inches, it would satisfy the theorem since 20+27 = 47. Therefore, these lengths can form a triangle.For the rods with lengths of 20 inches, 47 inches, and 67 inches, the sum of the two shorter lengths (20+47 = 67) is not greater than the length of the longest rod (67). Hence, these lengths cannot form a triangle.Similarly, for rods measuring 20 inches, 27 inches, and 67 inches, the sum of the two shorter rods (20+27 = 47) is less than the length of the longest rod (67). Therefore, this combination can't form a triangle either.Learn more about Triangle Inequality Theorem
