In triangle XYZ, m∠Z = (5m − 16)° and the exterior angle to ∠Z measures (3m + 12)°. Determine the value of m.
m = 3
m = 10.8
m = 18
m = 23
Answer:
Step-by-step explanation:
Each Exterior angle = 180° - Interior angle.
(3m + 12)° = 180° - (5m − 16)°
Then solve algebraically:
\(3m+12=180-5m-16\)
\(3m+12=-5m+164\)
\(8m+12=164\)
\(8m=152\)
m = 19
The value of m will be 23.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In triangle XYZ,
⇒ m ∠Z = (5m − 16)°
And, the exterior angle to ∠Z measures (3m + 12)°.
Now,
Since, The sum of angle and its exterior angle in a triangle will be 180°
Hence, We can formulate;
(5m − 16)° + (3m + 12)° = 180
Solve for m as;
5m - 16 + 3m + 12 = 180
8m - 4 = 180
8m = 180 + 4
8m = 184
m = 23
Thus, The value of m will be 23.

Match each hypotenuse length with the leg lengths that will create a right triangle.
Answer:
see attached
Step-by-step explanation:
The Pythagorean theorem can be used to find the hypotenuse associated with each pair of legs. That tells you ...
c² = a² +b² . . . . . legs a, b; hypotenuse c
__
alternate form of Pythagorean theoremFor the purpose of this problem, it is convenient to consider a slightly different form of the equation.
For legs √a and √b, the hypotenuse √c is given by ...
(√c)² = (√a)² +(√b)²
c = a +b
That is ...
legs √a, √b ⇒ hypotenuse √(a+b)
__
application to this problemSince the legs are (mostly) given in terms of square roots, the value under the radical for the hypotenuse is simply the sum of those:
legs: √1, √2 ⇒ hypotenuse √(1+2) = √3
legs: √2, √3 ⇒ hypotenuse √(2+3) = √5
legs: √5, √3 ⇒ hypotenuse √(5+3) = √8
legs: √5, √1 ⇒ hypotenuse √(5+1) = √6
_____
Additional comment
You may not see the leg lengths given as square roots very often. This is a rather unusual set of problems for hypotenuse length.

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Hailey goes to a restaurant and the subtotal on the bill was x dollars. A tax of 7% is applied to the bill. Hailey decides to leave a tip of 20% on the entire bill (including the tax). Write an expression in terms of x that represents the total amount that Hailey paid.
The total amount that Hailey paid can be represented by the following expression in terms of x:
Total amount = x + 0.07x + 0.20(x + 0.07x)
Simplifying the equation, we get:
Total amount = x + 0.07x + 0.20(1.07x)
Total amount = x + 0.07x + 0.214x
Total amount = 1.284x
Therefore, the expression in terms of x that represents the total amount that Hailey paid is 1.284x.

A 25-foot magazine rack begins 20 feet south of the checkout desk and continues south. What are the coordinates of the beginning and end of the magazine rack? Explain or show how you got your answer. ANSWER CORRECTLY WITH AN EXPLANATION
Answer: The coordinates of the beginning of the magazine rack are (0,-20), and the coordinates of the end of the magazine rack are (0,-45).
Explanation:
The magazine rack begins 20 feet south of the checkout desk, so its starting point is 20 feet below the x-axis. This gives us the coordinates (0,-20) for the beginning of the rack. Since the rack is 25 feet long, it extends 25 feet to the south of its starting point. Therefore, the endpoint of the rack is 20 feet (the starting point) minus 25 feet (the length of the rack), or -5 feet south of the checkout desk. This gives us the coordinates (0,-45) for the end of the rack.

Step-by-step explanation:
What is the nth term for 3, 10, 29, 66 and 127?
Answer:
3, 2, 7, 14, 23.
To find the nth term of a sequence, we need to identify the pattern or rule that generates the sequence.
Looking at the given sequence 3, 10, 29, 66, 127, we can see that each term is obtained by squaring the previous term and subtracting a constant value.
Specifically, we can see that:
10 = 3^2 + 1
29 = 10^2 + 9
66 = 29^2 + 7
127 = 66^2 + 1
So the pattern seems to be that each term is obtained by squaring the previous term and adding a constant value that increases by 2 for each successive term.
To find the nth term, we can use the formula:
nth term = (n-1)^2 + c
where n is the position of the term we want to find, and c is the constant value we add to the square of the previous term.
Using this formula, we can find the nth term as follows:
For the 1st term (n=1), we have 3 as the first term.
For the 2nd term (n=2), we have:
nth term = (n-1)^2 + c
= (2-1)^2 + 1
= 1 + 1
= 2
For the 3rd term (n=3), we have:
nth term = (n-1)^2 + c
= (3-1)^2 + 3
= 4 + 3
= 7
For the 4th term (n=4), we have:
nth term = (n-1)^2 + c
= (4-1)^2 + 5
= 9 + 5
= 14
For the 5th term (n=5), we have:
nth term = (n-1)^2 + c
= (5-1)^2 + 7
= 16 + 7
= 23
Therefore, the nth term for the given sequence is:
3, 2, 7, 14, 23.
hope this helps!
Answer:
Therefore, the 6th term of the sequence is 108.
Step-by-step explanation:
To find the pattern and the nth term for the sequence 3, 10, 29, 66, 127, we can look at the differences between the terms:
7, 19, 37, 61
The second differences are constant, which suggests that the original sequence is a polynomial of degree 2 (a quadratic). To find the formula for this quadratic, we can use the method of finite differences.
The first differences are:
7, 19, 37, 61
The second differences are:
12, 18, 24
The third differences are:
6, 6
Since the third differences are constant, we can assume that the formula for the sequence is of the form an^3 + bn^2 + cn + d, where a, b, c, and d are constants.
Using the first four terms of the sequence, we can set up a system of equations:
a(1)^3 + b(1)^2 + c(1) + d = 3
a(2)^3 + b(2)^2 + c(2) + d = 10
a(3)^3 + b(3)^2 + c(3) + d = 29
a(4)^3 + b(4)^2 + c(4) + d = 66
Solving this system of equations, we get:
a = 1/2
b = 3/2
c = 5/2
d = 1
Therefore, the formula for the nth term of the sequence is:
an^3 + bn^2 + cn + d = (1/2)n^3 + (3/2)n^2 + (5/2)n + 1
So, the nth term for the sequence 3, 10, 29, 66, 127 is:
an^3 + bn^2 + cn + d = (1/2)n^3 + (3/2)n^2 + (5/2)n + 1
To find the 6th term of the sequence, we can substitute n=6 in the formula:
a6 = (1/2)(6)^3 + (3/2)(6)^2 + (5/2)(6) + 1
= 108
Therefore, the 6th term of the sequence is 108.

A sporting goods store is having a sale in which all sleeping bags are discounted by 20%. Priya has a coupon for $5 off the regular price of a sleeping bag. The store first applies this coupon and then takes 20% off the reduced price. If Priya pays $34.40 for the sleeping bag, what was the original price, x, before the sale and without the coupon?
the original price was "x", which oddly enough is the 100%.
now, let's pluck out of "x" 5 bucks, so that makes it "x-5", that's our new adjusted 100%, from which the lady at the counter is happy to apply a 20% discount. Now, if the lady discounts 20% off of that "x-5" amount, what Priya is really paying for the sleeping bag is just 100% - 20% = 80%, and we happen to know that that 80% was really $34.40.
now, if "x - 5" is the 100%, and we know that 34.40 is the 80%, what the heck is "x"?
\(\begin{array}{ccll} amount&\%\\ \cline{1-2} x-5 & 100\\ 34.40& 80 \end{array} \implies \cfrac{x-5}{34.40}~~=~~\cfrac{100}{80} \implies \cfrac{ x-5 }{ 34.40 } ~~=~~ \cfrac{ 5 }{ 4 } \\\\\\ 4x-20=172\implies 4x=192\implies x=\cfrac{192}{4}\implies x=48\)
3/4 w=6 solve for w
Bc.
To solve for w, you need to isolate the variable on one side of the equation.
The equation is 3/4 w = 6.
To isolate w, you need to divide both sides of the equation by 3/4.
3/4 w / 3/4 = 6 / 3/4
The left side simplifies to w, because the 3/4 on the left side cancel out.
w = 6 / 3/4
To divide by a fraction, you need to multiply by its reciprocal.
w = 6 * 4/3
The right side simplifies to 8.
w = 8
Therefore, w = 8.
