Find the missing side length. Tell if the side lengths form a Pythagorean triple. Also, identify the correct explanation.
The missing side length is 17 and the side lengths 8, 15, and 17 form a Pythagorean triple.
Side lengths: 8, 15
Missing side length: 17
Yes, the side lengths form a Pythagorean triple. The side lengths 8, 15, and 17 form a Pythagorean triple because 8^2 + 15^2 = 17^2.
To answer this question, we first need to determine if the side lengths 8, 15 and the missing side length form a Pythagorean triple. To do this, we use the Pythagorean theorem which states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the longest side. If this is true, then the side lengths form a Pythagorean triple.
In this case, we can plug in the side lengths 8 and 15 into the Pythagorean theorem. 8^2 + 15^2 = 17^2. Since the equation is true, this means that the side lengths 8, 15 and 17 form a Pythagorean triple. Therefore, the missing side length is 17.

Juanita has saved 20% of the money that she needs to buy a new bicycle If she has saved $36 how much money does the bycycle cost
Answer:
$180
Step-by-step explanation:
20*5=100
36*5=180
Answer: the cost of the bicycle is 180$
Step-by-step explanation:
If Juanita has saved 20% of the money she needs to buy a new bicycle and she has saved $36, we can calculate the cost of the bicycle using the following formula:
(100% - 20%) x cost of bicycle = $36
To find the cost of the bicycle, we can divide both sides of the equation by 80% (100% - 20%), like this:
cost of bicycle = $36 / (100% - 20%)
We know that Juanita has saved $36 and the percentage saved is 20% , so the cost of the bicycle is $180

how to find the acute angle of each angle in a triangle if the given angles are in the form of an equation
To find the acute angle of each angle in a triangle if the given angles are in the form of an equation follow the steps in the main answer part
What is the acute angle?To find the acute angles of a triangle given the angles in the form of an equation, you can use the following steps:
Write down the equation for the triangle's angles, typically in the form of "angle A + angle B + angle C = 180 degrees".Use the equation to solve for one of the angles. For example, if the equation is "angle A + angle B + angle C = 180 degrees", you can solve for angle A by subtracting angle B and angle C from 180 degrees.Repeat step 2 for the other angles.Check if the angles are acute or not. An acute angle is an angle that measures less than 90 degrees.If an angle is not acute, use the property of the triangle that the sum of all the angles is 180° and subtract the angle from 180° to get the acute angle.Example: Let's say you are given an equation,
A+B+C = 180°
If
A = 70°
B = 70° then
C = 40°
C is not acute, so subtract it from 180° to get C= 140°
Now you have A = 70° and C = 140° which are acute angles.

Keith's unpaid balance is $178.62, finance charge is $2.6795 and new balance is $181.2995
Kieth's unpaid balanceTo find Keith's unpaid balance, we need to find the difference between the previous balance and the payments made during the month.
Keith's previous balance was $200.
During the month, he charged $178.62, made a $200 payment.
So, Keith's unpaid balance is:
$200 (previous balance) - $200 (payment) + $178.62 (charges) = $178.62
Finance chargeTo find Keith's finance charge, we need to multiply the unpaid balance by the monthly periodic rate (1.5% in this case).

m=-2/3b=-4 Write in slope intercept form, solve, graph
The equation for a slope of -2/3 and an intercept of -4 is 2x+3y+12=0.
What is equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation. Linear equations are classified into three types: point-slope, standard, and slope-intercept.
Here,
y=mx+b
m=-2/3
b=-4
y=-2/3x+(-4)
y=-2x/3-4
3y=-2x-12

He tax rate a a percent, r, charged on an item can be determined uing the formula StartFraction c Over p EndFraction minu 1 equal r. – 1 = r, where c i the final cot of the item and p i the price of the item before tax. Louie rewrite the equation to olve for the final cot of the item: c = p(1 ). What i the final cot of a $40 item after an 8% tax i applied?
A $40 item will ultimately cost $43.2 when an 8% tax is included.
The formula Lousie used is:
c = p(1 + r)
We will solve this problem with the help of percentages.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
We are given that the price of the item is $40
r = 8% .
Therefore,
c = 40(1 + 8%)
c = 40 (1 + 8/100)
c = 40 ((100+8)/100)
c = 40 (108/100)
c = 40 * 1.08 = 43.2
Final cost = $43.2
Therefore the final cost of the $40 item after an 8% tax is applied will be $43.2.
