The Pythagorean Theorem states that for Right Triangles:
[tex]c^2=a^2+b^2[/tex]Where "c" is the hypotenuse (the longest side of the triangle), and "a" and "b" are the legs of the Right Triangle.
In this case, you can see that the exercise provides the length of the legs of the Righ Triangle, but you don't know the hypotenuse. Then, you can set up that:
[tex]\begin{gathered} a=6\operatorname{cm} \\ b=8\operatorname{cm} \end{gathered}[/tex]Therefore, you can substitute values into the equation that represents the Pythagorean Theorem and solve for the hypotenuse:
[tex]\begin{gathered} c^2=(6\operatorname{cm})^2+(8\operatorname{cm})^2 \\ c=\sqrt[]{(6\operatorname{cm})^2+(8\operatorname{cm})^2} \\ \\ c=\sqrt[]{100\operatorname{cm}^2} \\ c=10\operatorname{cm} \end{gathered}[/tex]Hence, the answer is:

Labeled the given triangle as shown below:
The coordinates of triangle ABC are:
A(-4, -2)
B(0, -4)
C(2, 2)
The translation of the triangle 4 units to the left and 3 units down will be given as:
A(-4, -2) → A'(-8, -5)
B(0, -4) → B'(-4, -7)
C(2, 2) → C'(-2, -1)

Sean has $900 in a savings account that earns 5% annually. The interest is notcompounded. How much will he have in 1 year?Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), ris the interest rate expressed as a decimal, and t is the time in years.Submit
Answers
Answer:
The interest after one year is $45
Explanation:
Principal = $900
Rate = 5%
Time = 1 year
I = P x R x T / 100
I = 900 x 5 x 1 / 100
I = 4500/100
I = $45
Therefore, the interest after one year is $45
A map of Levi's property is being made with a scale factor of 2 centimeters: 3 meters. Whats the scale factor
Answers
As a result, if 2 centimeters on the map equals 3 meters, you might express that as a fraction and convert it to a standard unit of meters: 0.02 / 3, which you could then multiply by 50 / 50 to get the fraction 1 / 150. The scale factor 1 is 150.
What is Scale Factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2. The new figure we receive will resemble the first figure, but every dimension will be double that of the first rectangle. The scale factor in this case will be denoted by the number 2.Scale factor = Dimension of the new shape Dimension of the original shape is the fundamental formula used to calculate it. The formula is expressed as Scale factor = Larger figure dimensions Smaller figure dimensions in the event that the original figure is enlarged.

A man who weighs 200 lbs goes on a diet and loses 16%of his body weight. How much weight, in ounces, did he loses?
Answers
We know that the man loses 16% of his weight, to find how much was that we just have to multiply his total weight by 0.16, like this:
lost weight = 0.16 * total weight, by replacing 200 lbs for total weight, we get:
lost weight = 0.16 * 200 = 32
Now we need to express 32 lbs in ounces, we can do this by multiplying the weight in pounds by 16, since 1 pound is equivalent to 16 ounces, then we get:
lost weight in ounces = 32 * 16 = 512
Then, the man lost 512 ounces

The weights of the first and second alloys to be used are 23.707 and 30.293 pounds.
The percentage of titanium in the first alloy is 29%.The percentage of titanium in the second alloy is 70%.Let the weight of the first alloy taken be "x".Let the weight of the second alloy taken be "y".The percentage of titanium in the third alloy is 52%.The weight of the third alloy is 54 pounds.The weights of the first and second alloys taken are equal to the weight of the third alloy.x + y = 54We also know that the third alloy is made using the first and second alloys.29x + 70y = 52*5429x + 70y = 2808We have a system of two equations in two variables.Upon solving, we get the values of "x" and "y".The value of "x" is 23.707.The value of "y" is 30.293.To learn more about equations, visit :

Interpret the decay factor from the exponential function y = 900(0.65)3.
Answers
Answer:
0.65
Explanation:
If we have an exponential equation of the form
[tex]y=ab^x[/tex]where
a = inital amount
b = decay factor
Now in our case, the function we have is
[tex]y=900(0.65)^x[/tex]therefore,
the inital amount = 900
the decay factor = 0.65
Hence, the decay factor of the exponential function is 0.65.

Joseph is incorrect the car was traveling 24 feet per second because 600÷25=24 feet per second D. Joseph is incorrect the car was traveling 25 feet per second because 600÷24=25 feet per second
Answers
D. Joseph is incorrect the car was traveling 25 feet per second because 600÷24=25 feet per second
Explanations:Distance raced in 24 seconds = 600 Feet
Distance raced in 1 second = 600 / 24
Distance raced in 1 second = 25 feet
Therefore, the speed of the car = 25 feet per second
Joseph said the speed = 20 feet per second
Joseph is incorrect because the car was travelling 25 feet per second
Determine whether the given numbers represent the lengths of sides of a right triangle.9,40,41Do the given numbers represent the lengths of the sides of a right triangle?YesNo
Answers
To prove that these numbers form the sides of a right triangle we should do these steps
1. Square the longest side
2. Find the sum of the squares of the other 2 sides
3. If the sum equals the square of the longest side, then the numbers can form a right triangle
Since the longest side is 41, then
[tex](41)^2=1681[/tex]Since the other 2 numbers are 40 and 9, then
[tex](40)^2+(9)^2=1600+81=1681[/tex]From both steps, we can say
[tex](41)^2=(40)^2+(9)^2[/tex]Then the answer is
YES, 9, 40, 41 can form the sides of a right triangle
Use the Law of Sines to find the indicated angle 0. (Assume C = 67º. Round your answer to one decimal place.)

40.3º
Explanation
The Sine rule is used to solve angles and sides of triangle.
If a triangle ABC has angles A, B and C at the points of the named vertices of the tringles with the sides facing each of these angles tagged a, b and c respectively, the sine rule is given as
[tex]\frac{\text{ Sin A}}{a}=\frac{\text{ Sin B}}{b}=\frac{\text{ Sin C}}{c}[/tex]For this triangle,
Angle A = ? (Isn't given)
Angle B = θ
Angle C = 67º
Side a = ? (Isn't given)
Side b = 56.3
Side c = 80.2
We are then told to find the Angle B, that is, θ
So, using the later parts of the Sine Rule
[tex]\frac{\text{ Sin B}}{b}=\frac{\text{ Sin C}}{c}[/tex]Substituting the known variables, we have
[tex]\begin{gathered} \frac{\text{ Sin B}}{b}=\frac{\text{ Sin C}}{c} \\ \frac{\text{ Sin }\theta}{56.3}=\frac{\text{ Sin }67º}{80.2} \\ \text{ Sin }\theta=\frac{56.3\times\text{ Sin }67º}{80.2}=\frac{56.3\times0.9205}{80.2} \\ \text{ Sin }\theta\text{ = 0.6462} \\ \theta=Sin^{-1}(0.6462)=40.3º \end{gathered}[/tex]Hope this Helps!!!

C = dπ
is the formula for calculating circumference with diameter.
As a result, to calculate the diameter from the circumference, divide the circumference value by π, where π = 22/7 or 3.142.
⇒ d= C/π
here given C= 150 cm
by substituting the values ,
d = 150/3.14

Find the value of x.
Answers
Answer:
x = 82
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides = (n-2) x 180°
This polygon has 7 sides so the sum of its interior angles
= (7-2) x 180°
= 5 x 180°
= 900°
Adding up the given angles we get
x + 160 + 2x + 125 + 110 + 112 + 147 = 900
3x + 654 = 900
3x = 900 - 654
3x = 246
x = 246/3 = 82
Answer:
x = 82
Step-by-step explanation:
Sum of interior angles of a polygon
[tex]S=(n-2) \times 180^{\circ}[/tex]
where n is the number of sides.
The given polygon has 7 sides:
n = 7To find the value of x, substitute the sum of the interior angles and the found value of n into the formula and solve for x:
[tex]\implies x+160+2x+125+110+112+145=(7-2)\times 180[/tex]
[tex]\implies x+2x+160+125+110+112+145=5\times 180[/tex]
[tex]\implies 3x+654=900[/tex]
[tex]\implies 3x+654-654=900-654[/tex]
[tex]\implies 3x=246[/tex]
[tex]\implies \dfrac{3x}{3}=\dfrac{246}{3}[/tex]
[tex]\implies x=82[/tex]
Therefore, the value of x is 82.

Answer:
x = 11
Step-by-step explanation:
all angles in a triangle will add up to 180.
So we can start with the equation:
(19 + x) + (7 + 8x) + angle str = 180.
we are given the angle stv. This angle equals 125.
the angle of a straight line is 180. In order to find the angle next to another angle like angle stv and str are, all you have to do is subtract the angle from 180.
So to find str:
180 - 125 = 55
we already have one of our angles which is 55
so the equation is now:
(19 + x) + (7 + 8x) + 55 = 180
now do some simple simplification:
(19 + x) + (7 + 8x) + 55 = 180
______________ -55_-55
(19 + x) + (7 + 8x) = 125
26 + 9x = 125
-26_____-26
9x = 99
99/9 = 11
x = 11
Therefore, x = 11
