Which statements is/are TRUE in a 45° - 45° - 90° triangle?|. The legs are congruentII. The length of the hypotenuse is twice the length of the shorter legIII. The length of the longer leg is V3 times the length of the shorter legIV. The length of the hypotenuse is v2 times the length of a legA. I onlyB. I and IIC. II and IIID. I and IV
i and iv are correct in a 45° - 45° - 90° triangle?|. The legs are congruentII. The length of the hypotenuse is twice the length of the shorter leg.
in 45 -45-90 triangle the legs are both 1 units in length and the hypotenuse is sqrt 2
sqrt2 ^2 = 1^2+1^2
this denotes our measurement is true
if the legs ofa right triangle are a and b and the hytponuse is c then
a²+b²=c²
lets say
a>b
so
longer leg is 4ft longer than shorter
a=4+b
hypotnuse is 8ft longer than shorter
c=8+b
teh equation in terms of b and solve
a²+b²=c²
subsitute
(b+4)²+b²=(b+8)²
b²+8b+16+b²=b²+16b+64
2b²+8b+16=b²+16b+64
minus (b²+16b+64) from both sides
b²-8b-48=0
what 2 numbers multiply to get -48 and add to get -8?
-12 and 4
(b-12)(b+4)=0
set equal to 0
b-12=0
b=12
b+4=0
b=-4
false, can't have negative length
b=12
so
a=4+b
a=4+12
a=16
c=8+b
c=8+12
c=2
shorter leg: 12ft
longer leg: 16ft
hypotonuse: 20ft

The minimum and maximum possible volume for a rectangular right prism are 1221.875 and 1603.125 cubic inches.
What are the minimum and maximum possible volume of a rectangular prism?
In this problem we must determine the minimum possible and maximum possible volumes for a rectangular right prism, whose volume formula including length uncertainties is shown below:
V = (w ± Δw) · (l ± Δl) · (h ± Δh)
Where:
w - Width, in inches.l - Length, in inches.h - Height, in inches. Δw - Width uncertainty, in inches.Δl - Length uncertainty, in inches.Δh - Height uncertainty, in inches.Please notice that minimum possible volume is found when all "±" operators are replaced by "-" operators and that maximum possible volume is found when all "±" are replace by "+" operators. Given that statement does not mention the value of every length uncertainty, we assume that Δw = Δl = Δh = 0.5 in.
If we know that w = 12 in, l = 13 in, h = 9 in and Δw = Δl = Δh = 0.5 in, then the minimum and maximum possible volumes are:
Minimum possible volume
V = (12 in - 0.5 in) · (13 in - 0.5 in) · (9 in - 0.5 in)
V = (11.5 in) · (12.5 in) · (8.5 in)
V = 1221.875 in³
Maximum possible volume
V = (12 in + 0.5 in) · (13 in + 0.5 in) · (9 in + 0.5 in)
V = (12.5 in) · (13.5 in) · (9.5 in)
V = 1603.125 in³

How to create triangle ?Triangle Properties
A triangle's (of all varieties) total sum of angles is 180°.The length of a triangle's two longest sides added together is longer than the third side.Similar to this, the length of the third side of a triangle's third side is shorter than the difference between its two sides.Any two triangle sides can add up to a length that is longer than the third side. The greatest side of a triangle is the side that faces the largest angle. The sum of the triangle's internal opposing angles is equal to any of its outer angles.
According to the sides of a triangle rule, the lengths of any two sides of a triangle must add up to more than the length of the third side.
Sum of 2 sides each are :
7 + 10 = 17 cm

600=5+60 what was the annual interrest rate
On solving the provided question, annual rate is 2% while doing calculations through simple interest.
What is simple interest?Borrowers must pay simple interest to lenders as a fee for a loan. Compound interest is not taken into account while calculating it; just the principal is used. Simple interest is applicable to all loans. It is also the form of interest that banks give their customers on their savings accounts. Simple interest can be calculated using a simple formula. Simply multiply the loan's principal by the interest rate and the period to get the total. Although some mortgages employ this calculation approach, this type of interest typically relates to auto loans or short-term loans.
Let the annual rate be x%
Principal Amount (p)= $600
Annual Rate (r) = x % (Assumed)
Time (t) = 5 years
Simple Interest (I) = $60
Use the simple interest formula given below:
SI = p×r×t/100
r = 60 ×100/600× 5
r = 2%
Thus, the annual rate of interest is 2 %.

The length of the side of the given square is 12.3 inches approx.
What is a square?Due to the fact that this particular group of numbers makes up a square, they are known as square numbers (or squared numbers).
Finding the area of a square is easy because they all have equal sides. Just "square" (multiply by itself) one of their sides!
So, we have:
The area of the square is 151 in².
Area formula: s²
Now, calculate the length of the side as follows:
A = s²
151 = s²
s = √151
s = 12.3 approx

Sam is proving the product property of logarithms. Step justification given substitution which expression and justification completes the third step of her proof? ; power rule of exponents subtraction property of exponents multiplication rule of exponents division property of exponents.
Sam's rationale for the third step based on logarithm properties would be logb(b^x+y), power rule of exponents. Thus, the correct answer is C.
The first step of Sam's proof is to show that logb(MN) is equal to logb(b^x.b^y), which is a substitution of MN for b^x.b^y. This is based on the product property of logarithms, which states that logb(MN) = logb(M) + logb(N) for any positive numbers M and N and any base b, as long as b doesn't equal 1.
The third step of her proof is to simplify logb(b^x.b^y) further by applying the power rule of exponents, which states that:
b^(x+y) = b^x.b^ySo, by substituting b^(x+y) for b^x.b^y, we get:
logb(b^(x+y)) = logb(b^x+y)So, in short, the justification of the third step is based on the power rule of exponents, and it shows that logb(b^x.b^y) can be simplified further to logb(b^x+y).
The answer choice A, logb(b^xy), power rule of exponents, is incorrect because it implies that the third step is to multiply x and y instead of adding them.
This question should be provided with answer choices, which are:
A. logb(b^xy), power rule of exponents.B. logb(b^x-y), subtraction property of exponents.C. logb(b^x+y), power rule of exponents.D. logb(b^x/y), division property of exponents.The correct answer is C.

Answer: All Real Numbers Except "-8" (R - {-8})
Step-by-step explanation:
The domain of a function is all possible x values that the function can be defined with.
This means that if a value does not create any indeterminate situation, we can consider this value is in the domain of a function.
For this function, "-8" is not in the domain of the function because the denominator of a rational fraction cannot be zero in any case. This creates an indeterminate situation, therefore we do not consider "-8" in the domain of the function.
But for the other values, there is no problem since the denominator cannot be zero without x = -8.

Answer: 6/7 / 2/9 = 3/1 or 3 ✅
PLEASEEEE GIVE BRANLIEST
Step-by-step explanation:
To divide two fractions, you can invert the second one (the one being divided by) and then multiply the two fractions.
So:
(6/7) / (2/9) = (6/7) * (9/2)
To multiply the fractions, you just multiply the numerators together and multiply the denominators together.
(6/7) * (9/2) = (69)/(72)
= 54/14
So the final answer is 54/14.
You can also simplify the fraction by dividing the numerator and denominator by their greatest common factor.
54/14 = 3/1
So the final answer is 3/1 which is 3.

solve for x (x-1)(x-12)=0
Answer:
x = 1, 12
Step-by-step explanation:
Given the equation:

This can be set as:
[tex]\displaystyle{x-1 = 0 \ \, \text{or} \ \, x - 12 = 0}[/tex]
Solve equations like linear, add both sides by 1 for x - 1 and add both sides by 12 for x - 12:
[tex]\displaystyle{x-1 +1= 0+1\ \, \text{or} \ \, x - 12+12 = 0+12}\\\\\displaystyle{x= 1\ \, \text{or} \ \, x = 12}[/tex]
Instead of using "or" for conjunction, we can simply write the solution as x = 1, 12 (or you can also write x = 12, 1)

What is the rule of substitution?
In this rule, we have to find the value of any of the variables either first or second and substitute its value in the other equation.
It is best to use the substitution method when equations are either given in form or can be gain into the form of x = ay + b and y = mx + n.
A procedure to answer a system of linear equations in more than two variables algebraically is the substitution method. In this process, we find the value of any one of the variables by alienating it on one side and taking every other term on the other side of the equation.
Then we substitute that first value in the second equation.
The substitution method is one of the algebraic processes to answer simultaneous linear equations. It implies substituting the value of any one of the variables from one equation into the other equation.
And at last, we can put the value of y in any of the given equations to find x.
