When the bathroom at your house started to leak, the plumber came to fix it. In all, he used 18 feet of pipe, which came in either 2-foot or 4-foot sections. How many of each did he use if he needed 6 pieces of pipe
4 two foot and 2 four foot
3 two foot and 3 four foot
2 two foot and 4 four foot
5 two foot and 1 four foot
Answer:
3 two foot and 3 four foot
Step-by-step explanation:
In order to find how many of each he used, you have to find how much pipe in total with the options that were given you.
(3*2)+(3*4)=6+12=18 feet of pipe
A merchant offers a large group of items at 32% off later the merchant takes 16% off the sale prices and claims that the final price of these items is 186 off the original price.
what is the total percent discount?
The total discount was 48% of the original price of $387.50
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the original price.
Discount = (32% of x) + (16% of x) = 0.48x = 48% of x
The final price of these items is 186 off the original price.
x - 0.48x = x - 186
x = $387.50
The total discount was 48% of the original price of $387.50

Write an equation in slope-intercept form for the line that passes through the given point and has the given slope:
(1, 5)
Slope = -1
PLS HELP PLS PLS TYSM
Answer:
y = -x + 6
Step-by-step explanation:
We can plug the given point and slope into the point-slope formula and solve for the y-intercept formula.
y - y = m(x - x) <-- Point-Slope Formula
m = -1
(x,y) = (1, 5)
y - 5 = -1(x - 1)
y - 5 = -x + 1
y = -x + 6 <-- Y-intercept Formula

The radius of a sphere is 3 cm. What is the sphere's volume? Round to the nearest tenth.
Answer:
113.1
I answered this question before with the exact radius, and I remember the answer being this.
Formula:
V=4
3πr3=4
3·π·33≈113.09
Hope this helps!
Answer:
Step-by-step explanation:
the answer is 113.1 cm³
The volume of a sphere of radius r is V = (4/3)πr³.
If the radius is 3 cm and the answer is to be expressed to the nearest tenth, then we get:
V = (4/3)(3.14159)(3 cm)³
= (4/3)(84.82 cm³
= 113.1 cm³

What is the measure of B? C is 34 degrees.
Answer:
m<B= 56
Step-by-step explanation:
A triangle has 180 degrees. This is right triangle meaning there is one angle that is 90 degrees. That's angle A since it's indicated by the little box. So 90+34= 124. You then subtract that from 180 to get 56.
For the right triangles below, find the values of the side lengths d and b.
Write answers in simplified radical form if necessary.
Answer:
d = 2√2b = 5√3Step-by-step explanation:
In these special right triangles, the sides have length ratios ...
45-45-90: 1 : 1 : √2
30-60-90: 1 : √3 : 2
This tells us ...
d×√2 = 4 . . . . . . . . . . relationship between the side and the hypotenuse
d = 4/√2 = 2√2

Problem 3
Answer: Choice A and Choice C
-----------------------
Explanation:
Think of stacks of coins. Let's say we had 2 stacks of 10 quarters each. The quarters are identical, so they must produce identical volumes. Those sub-volumes then add up to the same volume for each stack. Now imagine one stack is perfectly aligned and the other stack is a bit crooked. Has the volume changed for the crooked stack? No, it hasn't. We're still dealing with the same amount of coins and they yield the same volume.
For more information, check out Cavalieri's Principle.
With all that in mind, this leads us to choice C. If the bases are the same, and so are the heights, then we must be dealing with the same volumes.
On the other hand, if one base is wider (while the heights are still equal) then the wider based block is going to have more volume. This leads us to choice A.
Hope makes 3 group of shapes
What Larger group to the shapes in a and B belong in
The shapes in the three groups are quadrilaterals
The shapes in group A and B belong to parallelograms and rectangles
How to determine the shapes?From the complete question, we can see that the shapes in the group A have opposite parallel sides and the angle between the adjacent sides is not 90 degrees.,
This means that the shapes in group A are parallelograms
Similarly, the shapes in the group B have opposite parallel sides and the angle between the adjacent sides is 90 degrees.
This means that the shapes in group A are rectangles
Hence, the shapes in group A and B belong to parallelograms and rectangles

replacement, what is the probability of
a getting two white balls?
Answer:40%
Step-by-step explanation:
10 divided by 2 is 5.
Since there are five balls, and four are white and one is red, if you double that amount, then you would have 8 white and 2 red. So four white balls is equal to 40%.

Matt took 12 hours to read a 792 page book.
Which rate best represents the relationship between the number of pages Matt reads to the amount of time it took for him to read it?
A. 67 hours per page
B. 66 pages per hour
C. 65 pages per hour
D. 804 hours per page
The representation of Matt's reading the book is an illustration of unit rates
The best representation of the rate is (b) Matt reads 66 pages per hour
How to determine the representation?
The given parameters are:
Pages = 792 pages
Time = 12 hours
The rate is then calculated as:
Unit Rate = Pages/Time
This gives
Unit Rate = 792/12
Evaluate the quotient
Unit Rate = 66
This means that Matt reads 66 pages per hour
