Which values of a, b, and c correctly represent the answer in simplest form? 3 and one-half divided by 2 and one-fourth = a StartFraction b Over c EndFraction a = 1, b = 5, c = 9 a = 10, b = 18, c = 1 a = 9, b = 5, c = 1 a = 1, b = 10, c = 18
Answers
Answer:
a = 1, b = 5, c = 9
Step-by-step explanation:
3 1/2 ÷ 2 1/4
= 7/2 ÷ 9/4
= 7/2 × 4/9
= (7*4)/(2*9)
= 28/18
= 14/9
= 1 5/9
Therefore
3 1/2 ÷ 2 1/4 = a b/c

There are 12 green,22 white, 12 purple and 4 blue gum balls in the gum all machine what is the probability of getting white gum all write the probability as a percent
Answers
Answer: If you add all of these numbers of gumballs up you get 50. Since there is 50 gumballs,and 100 percent of that amount has to be filled,then you must make each gumball worth 2 percent. (12x2)+(22x2)+(12x2)+(4x2)=100
Green percent of getting=24 percent
Purple percent of getting=24 percent
Blue percent of getting=8 percent
White percent of getting=44 percent
The percent of getting a White gum is 44 percent.

Han has Spent 75 minutes practicing the piano over the weekend priya practice the violin for 152% as much time as hand practicing piano how long does she practice
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

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

Answer:

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

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
