what’s the hypotenuse
Answers
explanation:
pythagorean theorem to find the hypotenuse ( which is c)
a^2 + b^2 = c^2
let’s just say a=5 and b = 12
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2 -> take the square root of both sides
√169 = √c^2
c = 13
OR you can memorize a few pythagorean triples and know 13 is the hypotenuse bc 5-12-13 is a pythagorean triple so 13 is the hypotenuse

Answers
Answer: 114 minutes
Step-by-step explanation:
From the question, we are informed that Han has Spent 75 minutes practicing the piano over the weekend while Priya practice the violin for 152% as much time as Han used in practicing the piano.
Therefore, the number of minutes used in practicing by Priya would be gotten by multiplying 152% by 75 minutes. This would be:
= 152% × 75 minutes.
= 152/100 × 75minutes
= 1.52 × 75 minutes
= 114 minutes

An angle measures 3.8° more than the measure of its complementary angle. What is the measure of each angle?
Answers
Answer: 41.2 degrees
Step-by-step explanation:
Complementary angles are angles that add to 90 degrees, so if they were equal, they would be 45 and 45, but since one is 3.8 more, it is 45+3.8 = 48.8 and the other, to add to 90 degrees is 90-48.8 = 41.2

Circle C has radius 5 and center C(6,-2). What is the equation of circle C ?
Answers
The equation of the circle C is [tex](x-6)^{2}+(y+2)^{2} =25[/tex]
Equation of a circle
The equation of a circle is [tex](x-h)^{2}+(y-k)^{2} =r^{2}[/tex] where r is the radius and (h,k) is the center of a circle.
How to find the equation of a circle for the given condition?The radius of a circle is 5.
Also, the center of a circle is (h,k) = (6,-2)
So, the equation of a circle is [tex](x-6)^{2}+(y-(-2))^{2} =5^{2}[/tex]
Simplify further the above equation.
[tex](x-6)^{2}+(y+2)^{2} =25[/tex]
Thus, the equation of the circle C is [tex](x-6)^{2}+(y+2)^{2} =25[/tex]
Hence, option (D) is correct.

Step-by-step explanation:
1) bisector means cutting an angle in half. the small lines between segment SM and MT mean they are congruent. this means MW is a bisector. Since both halves of ST are congruent, we know SM = 19. 19+19=38
2) same logic here, M bisects ST. set both halves of ST equal to each other and solve.
3x-6=x+8
2x+14
x=7
plug back in to find MT (7)+8=15. MT=SM so double 15 to get ST. ST=30
3) the bisector will be exactly halfway between the points.
4) find difference between x and y values, and divide by 2
2-2=0 0/2=0 x moves 0
13-1=12 12/2=6 y moves 6
so add 0 and 6 to 2,1 to get (2,7)
5) same process
6--6=12 12/2=6
6-0=6 6/2=3
add 6 and 3 to -6,0 to get (0,3)
6) find the change in x and y between the coordinate sets. (x: 1- -1=2) (y: 2-4=-2) take the opposite of those values and add them to M
(x:1-2=-1) (y:2+2=4)
(-1, 4) are the other coordinates for C
7) take the same steps
(x:3-1=2) (y:7-1=6)
use -2 and -6
(x:3-2=1) (y:7-6=1)
(1,1) are other coordinates for C
8) use distance formula
sqrt (x1-x2)^2 + (y1-y2)^2
sqrt(1--1)^2 +(2-4)^2
sqrt (2)^2 +(-2)^2
sqrt 4+4
sqrt 8
9) same process
sqrt (-1-3)^2+(-5--8)^2
sqrt (-4)^2 +(3)^2
sqrt 16+9
sqrt 25

Taylor is 15 years younger than Marty. Twice Marty’s age added to three times Taylors age totals 205. What are the ages of Taylor & Marty?
Answers
Answer:
Taylor's age = x = 35 years
Marty's age = y = 50 years
Step-by-step explanation:
Let
Taylor's age = x
Marty's age = y
Taylor is 15 years younger than Marty.
x = y - 15
Twice Marty’s age added to three times Taylors age totals 205.
205 = 2y + 3x...... Equation 1
Therefore, we substitute y - 15 for x in
205 = 2y + 3x...... Equation 1
205 = 2y + 3(y - 15)
205 = 2y + 3y - 45
Collect like terms
205 + 45 = 5y
250 = 5y
y = 250/5
y = 50 years
x = y - 15
x = 50 - 15
x = 35 years
Solving for x
Therefore:
Taylor's age = x = 35 years
Marty's age = y = 50 years
