For this type of question, you have to use the Pythagorean Theorem:
[tex]a^{2} +b^{2} = c^{2}[/tex]
In the theorem, a and b are the legs. To find the length of the hypotenuse, you have to square the lengths of the two legs and add it together. Then, find the square root of the sum.
First square both numbers.
[tex]a=12 \\ a^{2} = 12 \times 12 = 144[/tex]
[tex]b = 16 \\b^{2} = 16 \times 16 = 256[/tex]
Now that you have the numbers, you need to add them.
[tex]144+256=400[/tex]
Now you need to find the square root of 400 to find the length of the htypotenuse.
[tex]\sqrt{400} = 20[/tex]
The length of the hypotenuse is 20 cm, which is the 3rd choice
a. 15 cm x
b. 17 cm x
c. 20 cm ✔
d. 28 cm x

true or false, every relation is a function
Final answer:
The statement that every relation is a function is false, as a function requires each input from the domain to be associated with exactly one unique output in the range, unlike a general relation which can associate a single input with multiple outputs.
Explanation:
A function is a special type of relation where each element in the domain is paired with exactly one unique element in the range. This specificity is illustrated by considering a relation that contains ordered pairs sharing the same first element but with different second elements; such a relation cannot be a function since it violates the definition that each input (domain) must be associated with a unique output (range).
On the other hand, if a relation has pairs where the second elements (outputs) are the same but the first elements (inputs) are distinct, it still qualifies as a function. This is because the foundation of a function's definition pertains solely to the uniqueness of mapping from the domain to the range, without regard to the uniqueness of the range itself.

In isosceles triangle the length of the base is twice shorter than the length of a leg. The perimeter of this triangle is 50 cm. Find the lengths of all sides.
The length of the base is 10 and the length of each leg is 20.
In order to find this, we can start by making the length of the base x. Now we know that the legs are twice as long, which would make them 2x. Since there are two of them, we can add x + 2x + 2x and set equal to 50 to find the value of x.
x + 2x + 2x = 50
5x = 50
x = 10
Now we can plug this in for our leg length as well to find that.
2x = Leg
2(10) = Leg
20 = leg
Solve for v in terms of s, t, an u. U=tsv
Final answer:
To solve for velocity v in the provided equation U=tsv, divide both sides by ts to isolate v, resulting in v = U / (ts).
Explanation:
Solving for v in Terms of s, t, and u:
To solve for v in terms of s, t, and u given the equation U=tsv, we can rearrange the equation to isolate v. We start by dividing both sides of the equation by ts, which results in:
v = U / (ts)
This equation shows that the velocity v can be calculated if we know the initial velocity u, the time t, and the displacement s.

Find the value of b if the graph the equation y=−3x+b goes through the given point.
A(−2, 4) AND B(5,2)
Hello!
To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.
Since we are given two points, we can use those two points to find two different equations.
Remember that ordered pairs are written as (x, y).
A(-2, 4)
y = -3x + b
4 = -3(-2) + b
4 = 6 + b (subtract 6 from both sides)
-2 = b
A) Therefore, the equation of the first ordered pair is y = -3x - 2.
B(5, 2)
2 = -3(5) + b
2 = -15 + b (add 15 to both sides)
17 = b
B) The equation of the second ordered pair is y= -3x + 17.
Final answers:
A) y = -3x - 2B) y = -3x + 17Answer:
I got this problem wrong and to all the people out there you are solving for B on both of them
Thank you have a good day.
Step-by-step explanation:
The Yu family and the Sainz family went on vacation together and each family leased a car. The leasing company charged a flat rental fee for the week, plus a charge for each mile driven. The Yu's drove 222 miles; their car cost $110.30 for the week. The Sainz's drove 147 miles; their car cost $99.05. What is the linear equation that represents the cost of a rental car? Round to the nearest hundredth
Answer:
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Step-by-step explanation:
Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.
Let flat rental fee be c and cost per mile driven = m and miles driven = x
Total cost =y
Then y = mx+C is the linear equation.
to find m and c, we use the fact that y =110.30 when x = 222
i.e. 110.30 = c+222x
and similarly 99.05 = c+147x
Subtract to eliminate c
11.25 = 75 x
0.15 =x
Substitute in I equation
110.30 = c+222(0.15)
c = 77
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Answer:
y=0.15x + 77.00

patrick was born with 1\7 of his faults and acquired the rest during his teenage years. if he was born with 326 faults, how many does he have total?
Answer:
i think it is 2,282
Step-by-step explanation:
break it down 300 x 7 is 2,100 20 x 7 is 140 and 7 x6 is 42
addit together and you have your answer
Answer: 2282
Step-by-step explanation:
To get the answer, first we make an equation.
Lets use f for faults.
So we know that Patrick was born with 326 faults. He had 1/7 the number of faults he has now when he was born. The question is asking how many faults he has in total. Now we can set up our equation.
326 = 1/7f
326 is on the left of the equal sign because 326 is equal to 1/7 the number of faults he has now. Next, because 1/7 is 1 divided by 7, we multiply 1/7f by 7. We get 1f or f because there is only 1 f. But what we do to one side we must do to the other. So when we multiply 7 to 1/7f we also multiply 7 to 326. This is our answer:
2282 = f

What is the average rate of change for the sequence shown below? a coordinate plane showing the points negative 1, 4. 1, 3. 3, 2. 5, 1.
Answer: - 1/2 = - 0.5
Explanation:
1. Make the sequence clear. These are the given points (x,y):
(-1, 4)(1, 3)(3, 2)(5, 1)2. The average rate of change only takes into account the last and the first pairs of your intervals, those are (5, 1) and (-1, 4).
Average rate of change = [change in y] / [change in x] = [1 - 4] / [5 - (-1) ] =
= - 3 / 6 = - 1/2 = - 0.5 ← answer
The averate ratre of change is the slope of the line that joins the first and last points. The fact that the result is negative means that there was a net decrease of the values.

A triangle has side lengths of 7 in., 9 in., and 11 in. Determine whether this is a right triangle and why.
Answer:
Not a right triangle. See below for my reasoning.
Step-by-step explanation:
If this is a right triangle, then the sum of the squares of the two shorter sides will equal the square of the longest side: 7^2 + 9^2 = 11^2 => 49 + 81 = 121 But this is false.

Ok so for this one I have to write an equation, solution, and answer.
Two groups hikers start at the same time at the same average speed. Marks group hikes for 2.5 hours. Sally’s group hikes for 4.7 hours and covers another 7.7 miles.
How fast are the hikers going?
Equation:_________
Solution: _________
Answer:___________
Final answer:
To find the hikers' average speed, we use the difference in distance and time between two groups, yielding an average speed of 3.3 miles per hour.
Explanation:
To solve the problem of how fast the hikers are going, we need to calculate the average speed using the distance covered by Sally's group and the time difference between the two groups. The formula for average speed is Average speed = Total distance ÷ Total time.
Let's denote the average speed as v, the distance covered by Marks' group as d (which is the same as Sally's since they start at the same point and hike at the same speed but for different periods), and their respective times as t1 for Marks' group and t2 for Sally's group.
Given:
Sally's group covers 7.7 miles more than Mark's group
t1 = 2.5 hours and t2 = 4.7 hours
Equation: Since they have the same speed, Mark's distance d plus 7.7 miles equals the speed v multiplied by t2 (Sally's hiking time). So, d + 7.7 = v × t2. Also, because speed is constant, v = d ÷ t1. Combining these, we get v = 7.7 ÷ (t2 - t1).
Solution: Substitute the given values into the formula, v = 7.7 ÷ (4.7 - 2.5)
Answer: v = 3.3 miles per hour.

Start 176 80
Donate x x Subtract
What's left 176 - x 80 - x
Equation
176 - x = 5*(80 - x) Olivia had 5 times as many books as Dawn did. Remove the brackets.
Solution
176 - x = 400 - 5x Add 5x to both sides
176 + 5x - x = 400 Combine terms on the left
176 + 4x = 400 Subtract 176 from both sides
4x = 400 - 176 Combine terms on the right.
4x = 224 Divide by 4
x = 224/4

What is the perimeter of the polygon shown?
The perimeter of a polygon is calculated by adding up the lengths of all its sides. In the case of a regular polygon (all sides equal), it's the length of one side times the number of sides. To answer the specific question, each side must be measured and added up.
Explanation:In mathematics, the perimeter of a polygon is the sum of the lengths of its sides. If the polygon has all equal sides, like a square or regular hexagon, you just multiply the length of one side by the number of sides. If not, you have to add up the lengths of all the sides individually.
For example, if we have a triangle with sides 3, 4, and 5 units long, the perimeter would be 3+4+5 = 12 units. Or, for a square with each side 4 units long, the perimeter would be 4*4 = 16 units. Without seeing the actual polygon in your question, I can't provide the exact perimeter, you’d need to measure each side and add them together or use a formula if it’s a regular shape with equal sides.

determine the tax if a flat tax of 15% is applied to an income of $400,000.
Hey there!
Let's start by simply finding 1% of $400,000.
To do this we can divide by 100, since 1% is the same thing as 1/100.
400,000 ÷ 100 = 4,000
Next, we can multiply 4,000 by 15, because 4,000 is 1% and we are looking for 15%.
4,000 x 15 = 60,000
This means the tax is $60,000.
Hope this helps!
