Answer:
(a) 136 ft
(b) $680
Step-by-step explanation:
You want to know the perimeter length and the cost of tiling around a pool with the L-shape shown.
(a) PerimeterThe sum of horizontal lengths at the bottom of the pool outline is the same as the length at the top.
The sum of vertical lengths at the left of the pool outline is the same as the length on the right.
The perimeter is the sum of horizontal and vertical lengths of the outline, so is ...
P = 2(40 ft + 28 ft) = 136 ft
The perimeter of the pool is 136 ft.
(b) Tile costThe cost of tile is found by multiplying the cost per length by the length around the pool.
tile cost = ($15/(3 ft))(136 ft) = $680
It will cost $680 to put tiles around the edge of the pool.

You toss a coin (heads or tails), then spin a three-color spinner (red, yellow, or blue). Complete the tree diagram, and then use it to find a probability.
1. Label each column of rectangles with "Coin toss" or "Spinner."
2. Write the outcomes inside the rectangles. Use H for heads, T for tails, R for red, Y for yellow, and B for blue.
3. Write the sample space to the right of the tree diagram. For example, write "TY" next to the branch that represents "Toss a tails, spin yellow."
4. How many outcomes are in the event "Toss a tails, spin yellow"? (1 point)
5. What is the probability of tossing tails and spinning yellow? (1 point)
Answers
Answer:
If the spinner has an even number of spaces,
1
8
. If the spinner has an odd number of spaces, more information is needed.
Explanation:
The answer depends on whether the spinner has an odd or even number of spaces.
If the spinner has an even number of numbers on it, there will be an equal number of odd and even numbers, meaning that the probability of spinning an odd number is
1
2
. This is also the probability of flipping heads on a coin. And so we have:
1
2
×
1
2
×
1
2
=
1
8
If the spinner has an odd number of numbers on it, the probability of spinning an odd number will vary. For instance, if there are 3 spaces on the spinner, the probability of spinning an odd number will be
2
3
. However, if there are 11 spaces, the probability will be
6
11
.
Step-by-step explanation:
The probability of tossing tails and spinning yellow is 1/6.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Outcomes of tossing a coin= {T,H}
Outcomes of spinner={ R,Y,B}
Now, outcomes are in the event "Toss a tails, spin yellow"
= {TY}
probability of tossing tails and spinning yellow,
= 1/2*1/3
= 1/6

A custodian can clean 2 classrooms in 15 minutes. At this rate, how many classrooms can a custodian clean in 76 minutes?
Answers
Answer:
10 Classroom
Step-by-step explanation:
Since,
Custodian clean 2 classrooms in 15 minutes
Then ,
Let's see how many minutes does it takes for a custodian to clean for 1 classroom
To Find that we have to divide the given minutes by the given classroom.
15/2 = 7.5
Hence, in 7.5 minutes a custodian clean 1 classroom
Therefore:
Classroom to minutes:
1 = 7.5
2 = 15
3 = 22.5
4 = 30
5 = 37.5
6 = 45
7 = 52.5
8 = 60
9 = 67.5
10 = 75
11 = 82.5
Hence, we round to the nearest number:
which is 10 classroom in 75 minutes.
For this reason, the answer is about 10 classroom

Find the area of a right triangle with a base of 9 feet and a hypotenuse length of 13 feet and a base of 9 feet.(Round to the nearest tenth.)
Answers
Answer:
Step-by-step explanation:
Remark
The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.
Formulas
c^2 = b^2 + a^2
Area = 1/2 b * a
Givens
c = 13 feet
a = ?
b = 9 feet.
Answer: 42.2 square feet.
Solution
c^2 = b^2 + a^2
13^2 = 9^2 + a^2
169 = 81 + a^2 Subtract 81 from both sides.
169 - 81 =81 - 81 + a^2 Combine
88 = a^2 Take the square root of both sides
√a^2=√88
a = 9.381
Area = 1/2 * 9 * 9.381
Area = 42.21
Rounded to the nearest 1/10 Area = 42.2

Find the interquartile range of the data.
132.127.106.140.158.135,129,138
Answers
First order the numbers
106,127,129,132,135,138,140,158
Now find the median (find the middle number)
It’s 132 and 135 so just add them together and divide by 2 so 133.5
Now to find Q1 you take the left overs from the first part of the medium and find the middle number
106,127,129,
⬇️
It’s 127 that’s the Q1
Now to find the Q3 you do the same thing but the upper half of the left overs
138,140,158
⬇️
Q3 is 140
Now that we know our Q1 is 127 and our Q3 is 140 we use the equation Q3-Q1
So
140-127=13

The area of the quadrilateral is equal to 15 square units.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the quadrilateral in a two-dimensional plane is called the area of the quadrilateral. A quadrilateral is a four-sided polygon with four edges and four corners in geometry.
Given that the quadrilateral has a height of 3 units, the base is 3 units and the upper sides are 7 units.
The area of the quadrilateral is calculated by the formula,
Area = (1/2) x h x (a + b)
Substitute the values in the formula and calculate the area,
Area = (1/2) x 3 x (7 + 3)
Area = (10 / 2) x 3
Area = 5 x 3
Area = 15 square units

multiply "Y" and "X" and you get 78ft.
"W" + "?"= "Y" If "W"=7, what is 13 ("Y") - 7? 13 -7=6. so "?"=6.
"Z"-"X"="?" "Z"=8 and "X"=6. so 8-6=2
2x6=12 *but remember that to find the area of a triangle it is half of a square of rectangle so you have to divide it in half. 12/2=6.

There are 357 basketball fans who plan to go to a game. How many buses will be needed, given that each bus can hold 45 fans?
Answers
Answer:
8 buses
Step-by-step explanation:
So if we want to seperate out a group of objects to a set, we would used division. Our group of objects is basketball fans and our set is a bus.
Now, we divide the group of objects by the set, to find how many sets to fit all the objects.
357/45 = 7.93333
Since we have a mixed number with a fraction, we will always round up. Because we can't have part of a bus and if we round down, we will not have enough buses.
So we need 8 buses

Option A doesn't work since angle C doesn't equal to angle K even though they are alternate interior angles which means angle D won't equal to angle L so A-A theorem doesn't work
Option B: they aren't congruent (you can tell just by looking at them) congruent implies that they are identical in side length and angle
Option C: its option C since just by looking at the figure, we know that the side length arent the same, and non of the angles are congruent to each other (excpet angle J since its a vertical angle).
option D: not all triangles are similar
