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.)
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
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)
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

Answer:
πr + 2r
Step-by-step explanation:
Perimeter of Semicircle
The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.
Step-by-step explanation:
1. d = 22mm
circumference = πr + d
= 22/7 × 11 + 22
= 56.57 mm
2. r = 4 inches
circumference = πr + d
= 22/7 × 4 + 8
= 20.57 Inches
3. d = 10 yards
circumference = πr+d
= 22/7 × 5 + 10

Answer:
1,2,4,8,2
Step-by-step explanation:
For the first blank, it asks you to look at the change in y-value where the x-value changes from 0 to 1. As the y-value goes from 2 to 3 in this space, it is increasing by 1.
For the second blank, it asks you to look at the change in y-value where the x-value changes from 1 to 2. As the y-value goes from 3 to 5 in this space, it is increasing by 2.
For the third blank, it asks you to look at the change in y-value where the x-value changes from 2 to 3. As the y-value goes from 5 to 9 in this space, it is increasing by 4.
For the fourth blank, it asks you to look at the change in y-value where the x-value changes from 3 to 4. As the y-value goes from 9 to 17 in this space, it is increasing by 8.
For the fifth blank, it asks you to find the rate of change for the graph using the information we previously found. As you can see, the rate of change is 2 for this exponential function, as for every x-value increasing by 1, the change in y-value is multiplied by 2. In other words, if you look at the prior answers you can see that 1*2=2, 2*2=4, and 4*2=8, and all of these changes occur while the x-value increases consistently. Therefore, the grow factor is 2 for every interval of 1.

Step-by-step explanation:
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?
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

How do you do this???
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.

A custodian can clean 2 classrooms in 15 minutes. At this rate, how many classrooms can a custodian clean in 76 minutes?
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

can someone explain how to do circles and circumference
(geometry)
Answer:
Radius:
radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.
Diameter:
2 times the radius is the circle's diameter.
Circumference:
The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).

Compute x/y if
x + 1/y = 4 and
y + 1/x = 1/4
Please explain the process on how to solve it- I'll give brainliest!
Answer:
Y = 1/4x-1
X = 4y-1
Step-by-step explanation:
layout the equations :
x+1/y = 4 y+1/x = 1/4
solve the equations, remember to switch sides switch signs solving the equations will give us the value of the letter
x+1/y = 4
x+1 = 4y
x=4y-1
***
y+1/x = 1/4
y+1 = 1/4x
y = 1/4x-1
Let first consider the equations one by one and will be solving one by one ;
[tex]{:\implies \quad \sf x+\dfrac{1}{y}=4}[/tex]
Multiplying both sides by y will lead ;
[tex]{:\implies \quad \sf xy+1=4y}[/tex]
[tex]{:\implies \quad \boxed{\sf xy=4y-1\quad \cdots \cdots(i)}}[/tex]
Now, consider the second equation which is ;
[tex]{:\implies \quad \sf y+\dfrac{1}{x}=\dfrac14}[/tex]
Multiplying both sides by x will yield
[tex]{:\implies \quad \sf xy+1=\dfrac{x}{4}}[/tex]
[tex]{:\implies \quad \sf xy=\dfrac{x}{4}-1}[/tex]
[tex]{:\implies \quad \boxed{\sf xy=\dfrac{x-4}{4}\quad \cdots \cdots(ii)}}[/tex]
As LHS of both equations (i) and (ii) are same, so equating both will yield;
[tex]{:\implies \quad \sf 4y-1=\dfrac{x-4}{4}}[/tex]
Multiplying both sides by 4 will yield
[tex]{:\implies \quad \sf 16y-4=x-4}[/tex]
[tex]{:\implies \quad \sf 16y=x}[/tex]
Dividing both sides by y will yield :
[tex]{:\implies \quad \boxed{\bf{\dfrac{x}{y}=16}}}[/tex]
Hence, the required answer is 16

Answer:
Step-by-step explanation:
Answer is C
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
