Answer:
The length of the third side of the triangle is 8 units
Step-by-step explanation:
Here, since the two sides are adjacent a square, what this means is that the length of the square equals the length of the sides of the triangle adjacent to it.
Mathematically, the formula for the area of a square is L^2
With an area of 32 square units, the length of the side of this triangle is thus √(32) =
4√2 units
So we have two sides of the right triangle with length 4√2 units
Now we should know that this right triangle is an isosceles right triangle since the lengths of the adjacent and the opposite are equal.
Now to calculate the length of the third side which is the hypotenuse, we make use of the pythagoras’ theorem which states that the square of the longest side of a right triangle which is the hypotenuse is equal to the sum of the squares of the other two sides
Thus mathematically, the square of the hypotenuse length is 32 + 32 = 64
Let’s call the hypotenuse h for documentation purposes
h^2 = 64
h = √64
h = 8 units

Tony has a bag of 10 quarters, 12 nickels, and 8 dimes. Tony selects a coin, records it, then replaces it back in the bag before choosing again.
Find the probability he selects a quarter first, dime second, and nickel
third. Write your answer in a fraction in simplest form.
Please help me!!
Answer:
8/225
Step-by-step explanation:
The probability of each event would be the number of the type of currency that you have specified divided by the total number of coins, in this case the total amount of coins does not change as the coin returns to the bag.
The total number of coins is: 10 + 12 + 8 = 30
The probability of finding a quarter is:
10/30
The probability of finding dime is:
8/30
The probability of finding nickel is:
12/30
The final probability then is:
(10/30) * (8/30) * (12/30) = 960/27000
If we simplify this, dividing both numbers by 120, we are left with:
8/225

What are the solutions to the equation x2 - 4x = -1?
Answer:
x= [tex]2-\sqrt{3}[/tex] and x=[tex]2+\sqrt{3}[/tex]
Step-by-step explanation:
- transfer the -1 to the other side so that the equation reads as [tex]x^{2} -4x+1[/tex]
- factor! think about what numbers add -4 but also multiply to be 1
- you may then realize that there are no numbers with those characteristics
- since that is the case, we have to use the quadratic formula, which is:
[tex]\frac{-b+\sqrt{b^{2}-4ac }}{y}[/tex] and [tex]\frac{-b-\sqrt{b^{2}-4ac }}{y}[/tex]
- the equation is shown as [tex]a^{2}+b^{2}=c^{2}[/tex]
- using the numbers that correspond with those lettered values, plug it in the quadratic formulas
the solutions to the equation [tex]\( x^2 - 4x = -1 \) are \( x = 2 + \sqrt{3} \) and \( x = 2 - \sqrt{3} \)[/tex].
To find the solutions to the equation [tex]\( x^2 - 4x = -1 \)[/tex], we can follow these steps:
1. Move all terms to one side of the equation to set it equal to zero:
[tex]\[ x^2 - 4x + 1 = 0 \][/tex]
2. We can solve this quadratic equation using the quadratic formula:
[tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]
where [tex]\( a = 1 \), \( b = -4 \), and \( c = 1 \).[/tex]
3. Plug in the values and simplify:
[tex]\[ x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4(1)(1)}}{2(1)} \] \[ x = \frac{4 \pm \sqrt{16 - 4}}{2} \] \[ x = \frac{4 \pm \sqrt{12}}{2} \] \[ x = \frac{4 \pm 2\sqrt{3}}{2} \] \[ x = 2 \pm \sqrt{3} \][/tex]
So, the solutions to the equation [tex]\( x^2 - 4x = -1 \) are \( x = 2 + \sqrt{3} \) and \( x = 2 - \sqrt{3} \)[/tex].

On a map the distance between two towns is 12 centimeters. If 3 centimeters represents 90 miles what is the actual distance between the cities in miles
the actual distance between the two towns is 360 miles.
What is Scale?The ratio used to depict the relationship between the dimensions of a model or scaled figure and the corresponding dimensions of the real figure or object is called the scale. On the other hand, a scale factor is a value that is used to multiply all of an object's parts in order to produce an expanded or decreased figure.
Given, On a map, the distance between two towns is 12 centimeters.
Also given, 3 centimeters represent 90 miles on the map.
Since 12 centimeters represent the distance between the two towns on the map, we can set up the proportion:
3 centimeters : 90 miles = 12 centimeters : x miles
where x represents the actual distance between the two towns in miles.
To solve for x, we can cross-multiply and simplify:
3 centimeters * x miles = 90 miles * 12 centimeters
3x = 1080
x = 360
Therefore, the actual distance between the two towns is 360 miles.

Find the area of a semicircle
Answer:
18pi, or 56.52
Step-by-step explanation:
To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle
However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:
(pi x radius^2)/2 = area of semi-circle
(pi x 6^2)/2 = area of semi-circle
(36 x pi)/2 = area of semi-circle
18 x pi = area of semi-circle
18 x 3.14 = area of semi-circle
56.52 = area of semi-circle
The area of a circle is
[tex]\pi \: {r}^{2} [/tex]
So the area of a semicircle would be half of that, or
[tex] \frac{\pi}{2} {r}^{2} [/tex]
So just plug in the radius, six, to get this

If 1m = 3.3 ft, how many cubic feet is the Kuroshio Sea tank? Volume is 9,450. Show your calculations!
Answer:
339604.65 cubic feet
Step-by-step explanation:
We are given that 1 m is equal to 3.3 ft.
1 m = 3.3 ft
This means that if we find the volume of a cube of 1 m, we have its volume as:
[tex]1^3 = 1 m^3[/tex]
In the same way, the volume of a cube of 3.3 ft (1 m) is:
[tex]3.3^3 = 35.937 ft^3[/tex]
This means that:
[tex]1m^3 = 35.937 ft^3[/tex]
The Kuroshio sea tank has volume of [tex]9450 m^3[/tex]. Its volume in cubic feet is therefore:
[tex]1m^3 = 35.937 ft^3\\\\9450 m^3 = 9450 * 35.937 = 339604.65 ft^3[/tex]
The volume of the tank is 339604.65 cubic feet.

Final answer:
To find the answer, first multiply 9 by 8, then add 4, resulting in 76. Finally, subtract 55 to get the answer, which is 21.
Explanation:
To solve the problem, we need to first calculate the sum of 9g and 4 when g=8. This will be 9 × 8 + 4.
After calculating the sum, we will subtract 55 from this amount to get the final answer.
Following the steps:
Substitute the value of g: We are given that g = 8. So, we need to find the sum of 9 * 8 and 4.Calculate the sum: The sum of 9 × 8 and 4 is 72 + 4 = 76.Subtract 55:Finally, we subtract 55 from the calculated sum: 76 - 55 = 21.Therefore, when g = 8, subtracting 55 from the sum of 9g and 4 results in 21.

Add the increased amount to the original amount: £258 + £110.94 = £368.94
The 5th term in a geometric sequence is 160. The 7th term is 40. what are the possible values of the 6th term of the sequence?
A. +- 70
B. 70
C. +-80
D. 80
We have been given that the 5th term in a geometric sequence is 160. The 7th term is 40. We are asked to find the possible values of 6th term of the sequence.
We know that an geometric sequence is in form [tex]a_n=a\cdot r^{n-1}[/tex], where,
[tex]a_n[/tex] = nth term of sequence,
a = First term,
r = Common ratio,
n = Number of terms.
We will get two equations using our given information as:
[tex]160=a\cdot r ^{5-1}...(1)[/tex]
[tex]160=a\cdot r ^{4}...(1)[/tex]
[tex]40=a\cdot r ^{7-1}...(2)[/tex]
[tex]40=a\cdot r ^{6}...(2)[/tex]
Upon dividing equation (2) by equation (1), we will get:
[tex]\frac{40}{160}=\frac{a\cdot r^6}{a\cdot r^4}[/tex]
[tex]\frac{1}{4}=r^{6-4}[/tex]
[tex]\frac{1}{4}=r^{2}[/tex]
[tex]r^{2}=\frac{1}{4}[/tex]
[tex]\sqrt{r^{2}}=\pm\sqrt{\frac{1}{4}}[/tex]
[tex]r=\pm\frac{1}{2}[/tex]
Let us solve for a.
[tex]160=a\cdot (\frac{-1}{2})^{4}[/tex]
[tex]160=a\cdot \frac{1}{16}[/tex]
[tex]160\cdot 16=a\cdot \frac{1}{16}\cdot 16[/tex]
[tex]2560=a[/tex]
So our formula would be [tex]a_n=2560\cdot (\pm\frac{1}{2})^{n-1}[/tex].
We cannot determine whether the common ratio would be positive or negative, so we will take both values.
[tex]a_6=2560\cdot (\pm\frac{1}{2})^{6-1}[/tex]
[tex]a_6=2560\cdot (\pm \frac{1}{2})^{5}[/tex]
[tex]a_6=2560\cdot \pm \frac{1}{32}[/tex]
[tex]a_6=\pm 80[/tex]
Therefore, the 6th term of the sequence would be [tex]\pm 80[/tex] and option C is the correct choice.

=112000 cm^3 = 1mL
The water is 84000
Make this a fraction
84000/112000 = 3/4

1-3/4 = 1/4
It is 1/4 from the top
Find the volume of the treasure chest
V = 12*10*8 =960
Tower
V = pi r^2
3.14 * 10^2 *10
=3140
Water + chest + tower
84000+960+3140 =88100
This is less than 112000 so the water will not overflow
Answer:
a) 10 cm
b) Will not overflow
Step-by-step explanation:
8400 = base area × height
84000 = 70 × 40 × h
h = 30
From the top: 40 - 30 = 10cm
b) Capacity of the tank:
70 × 40 × 40

Combined volume of the two vessels:
(12 × 10 × 8) + (3.14 × 10² × 10)
960 + 3140
4,100 cm³
4100 = 70 × 40 × rise
rise = 1.464285715 cm
Since 1.464285715 < 10

In one year the perseid metor shower had a metor appear every 1/5 5 minutes on average That same year the Leonid metor shower had a metor appear every 4/2 3 minutes on average.
In one year, the Perseid meteor shower had a meteor appear every 1 1/5 minutes on average. That same year, the Leonid meteor shower had a meteor appear every 4 2/3 minutes on average. How many more meteors fell during the Perseid meteor shower?
Answer:
325,452 meteors
Step-by-step explanation:
We all know that :
We have 365 days in a year and in each day there are 24 hours, Likewise an hour has 60 minutes
SO, the total number of minutes in a year is :
365 × 24 × 60 = 525600 minutes
For Perseid meteor:
[tex]1 + \frac{1}{5} \\ \\ = 1 + 0.2 \\ \\ = 1.2[/tex]
So one meteor fall at 1.2 minutes interval Thus, in a year, we will have :
1 meteor - 1.2 minutes.
x meteor - 525600 minutes.
1.2x = 525600
[tex]x = \frac{525600}{1.2}[/tex]
x = 438000
∴ 438,000 meteors fell during the Perseid shower.
For Leonid meteor shower:
[tex]4 + \frac{2}{3} = 4.67[/tex]
So one meteor fall at 4.67 minutes interval Thus, in a year, we will have :
1 meteor - 4.67 minutes.
x meteors - 525600 minutes.
[tex]4.67x = 525600[/tex]
[tex]x = \frac{525600}{4.67}[/tex]
x = 112548
112,548 meteors fell during the Leonid Shower.
Finally , the numbers of more meteors that fell during the Perseid meteor shower is calculated by the difference in the number of Perseid meteor shower and Lenoid meteor shower. i.e
438,000 - 112,548 = 325,452
325,452 more meteors fell during the Perseid meteor shower
Answer:
For Leonid meteor shower: So one meteor fall at 4.67 minutes interval Thus, in a year, we will have : 1 meteor - 4.67 minutes. x meteors - 525600 minutes

Write an exponential model, y=a(b)^x, given the two points (9,171) and (10,190)
Please hurry!
Answer:
[tex]y = 66.25(1.11)^x[/tex]
Step-by-step explanation:
Let's plug in 9 for x and 171 for y into the given exponential equation:
y = [tex]ab^x[/tex]
171 = [tex]ab^9[/tex]
Now do the same with (10, 190):
190 = [tex]ab^{10}[/tex]
Write them both in terms of a and set them equal:
a = 171/[tex]b^9[/tex]
a = 190/[tex]b^{10}[/tex]
171/[tex]b^9[/tex] = 190/[tex]b^{10}[/tex]
Multiply both sides by [tex]b^{10}[/tex]:
171b = 190
b = 190/171 = 10/9 ≈ 1.11
Plug this in to find a:
a = 171 / (10/9)^9 ≈ 66.25
So, the exponential model is:
[tex]y = 66.25(1.11)^x[/tex]
Answer:
y = 66.25[(10/9)^x]
Step-by-step explanation:
171 = a(b⁹)
b⁹ = 171/a
190 = a(b¹⁰)
190 = a(171/a) × b
b = 190/171
b = 10/9
(10/9)⁹ = 171/a
a = 66.24890362
