In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what is the value of b, if c=5, a=3
Answers
Answer:
b = 4
Step-by-step explanation:
Try setting up the equation of the pythagorean theorem.
hypotenuse^2 = leg(a)^2 + leg(b)^2
c^2 = a^2+b^2
Now substitute what you know and solve for the unknown.
5^2 = 3^2+b^2
25 = 9 + b^2
b^2 = 25-9 = 16
b = 4.

First you need to find the slope of the two points.
The slope is -2
Then you use the slope intercept form to find the y intercept.
y=2x+b
You then have to plug in the x and y points.
6= -2(2) + b
6= -4+b
b=10
Lastly write using the slope intercept
y= -2x+10

39,000 over 12 = ?? Also, show your work so I can do the rest of these myself
Answers
Answer:
3,250
Step-by-step explanation:
Let's go from left to right, using multiple of 12 times a power of 10 in the process.
What is the closest multiple of 12,000 (12 * 10^3) to 39,000 without going over? That's 3 (36,000). That's the thousands digit in this answer.
12,000 * 3 = 36000
39000 - 36000 = 3000
What's the closest multiple of 1,200 (12 * 10^2) to 3,000 without going over? That's 2 (2,400). That's the hundreds digit.
1,200 * 2 = 2,400
3,000 - 2,400 = 600
What is the multiple of 120 (12 * 10) closest to 600 without going over? That's 5 (600, it's even!). That's the tens digit. Since it goes evenly, 0 is the ones digit.
120 * 5 = 600
600 - 600 = 0.
The answer to 39,000 over 12 is 3,250.

In 1970, the median home value was $20,000. By 2020, the median home value was $320,000. What is the percent increase in home value in those 50 years?
Answers
Answer:
1500%
Step-by-step explanation:
The formula for Percentage increase is
Increase/ Initial Amount × 100
Increase = Current Amount - Initial Amount
Increase = $320,000 - $20,000
Increase = $300,000
Percentage Increase =
$300,000/$20,000 × 100
= 1500%
The percent increase in home value in those 50 years is 1500%

-1/2
Step-by-step explanation:
Formula to find slope is y2-y1/x2-x1
Chose one ordered pair to be the 2 and the other one to be the 1
I chose the 2nd one to be 2.
Plug in the y-value from the 2nd ordered pair to y2 because its the 2.
Plug in the x-value from the 2nd ordered pair to x2 because its the 2.
Now you have 0-y1/5-x1
Do the same thing but for the 1.
Plug in the y-value from the 1st ordered pair to y1 because its the 1.
Plug in the x-value from the 1st ordered pair to x1 because its the 1.
Now you have 0-5/5--5
In this situation, you have 2 minus signs.
2 minus = 1 positive.
Now you have 0-5/5+5
Simplify.
Now you have -5/10.
Simplify.
-1/2.

plss answer activity 1.2.3 & 4

I will be happy if you help me
(╯︵╰,)
Answers
Answer:
Activity 1:-
1) Pi (π) is the ratio of circumference and the diameter of the circle which is 22/7. So
[tex]\frac{c}{d} =\pi = \frac{22}{7}[/tex]
[tex]=> c = \frac{22}{7} d[/tex] where circumference is directly proportional to diameter (d).
2) Area of a parallelogram = Altitude × Base
Base = 10 cm. So ,
[tex]A = 10a[/tex] where area (A) is directly proportional to altitude (a).
3) Let the fare of 1 unit distance be f
So, for distance d , total fare (F) will be [tex]F = fd[/tex] where total fare (F) is directly proportional to distance (d).
4) Let the distance be 'D' , speed be 's' & time be 't' .
We know that [tex]s = \frac{D}{t}[/tex] where speed (s) is directly proportional to distance (D) & inversely proportional to time (t).
5) We know that area of a square (A) = side² (s²)
[tex]=> A = s^{2}[/tex] where area(A) is directly proportional to side(s).
Activity 2:-
1) p is directly proportional to sum of u & w.
⇒ p ∝ u + w
⇒ p = k (u + w)
Putting the values of p , u & w
⇒ 14 = k(4 + 3)
⇒ 7k = 14
⇒ k = 14/7 = 2
2) r is directly proportional to square of t.
⇒ r ∝ t²
⇒ r = k × t²
Putting the values of r & t
⇒ 16 = k × 16²
⇒ k = 16² ÷ 16 = 16
3) y is directly proportional to cube root of x.
⇒ y ∝ ∛x
⇒ y = k × ∛x
Putting the values of x & y ,
⇒ 2 = k × ∛27
⇒ 3k = 2
⇒ k = 2/3
4) z is directly proportional to cube of d.
⇒ z ∝ d³
⇒ z = k × d³
Putting the values of d & z ,
⇒ 5 = k × 2³
⇒ 8k = 5
⇒ k = 5/8
5) Total Surface Area (SA) is directly proportional to square of the sides (s).
⇒ SA ∝ s²
⇒ SA = k × s²
Putting the values of SA & s ,
⇒ 96 = k × 4²
⇒ 16k = 96
⇒ k = 96/16 = 6

a quadrilateral has 2 angles that measure 100 and 60 degrees the other angles have a ratio of 3:17 . what are the measures of those angles?
Answers
Answer:
30° , 170°
Step-by-step explanation:
Let the remaining two angles be 3x & 17x. As it is a quadrilateral , the sum of all the angles of quadrilateral is 360°. So,
[tex]3x + 17x + 60 + 100 = 360[/tex]
[tex] = > 20x + 160 = 360[/tex]
[tex] = > 20x = 360 - 160 = 200[/tex]
[tex] = > x = \frac{200}{20} = 10[/tex]
Putting the value of x , remaining angles are
(3×10 = 30°) & (17×10 = 170°)
Step-by-step explanation:
the missing angles 3:173x+17x+60+100=360°20x+160=360°20x=360-16020x=200°divide both sides by 20X=10substitute X=10 in 3x and 17x3(10)=30°17(10)=170°Complete each statement to describe a diagram that represents each situation.
