Answer:

Just do 60/5 normally at first. You'll get 12, and after that simplify it even more to get 4 times 3. Now, pretend radicals exist again.

in the given figure pt is the bisector of angle qpr. qs=3x, rs=2x+2, pq=3y-1 and pr=y+5
1)solve the measure of rs
2)solve the measure of rq
3)solve the measure of pq
4)solve the measure of pr
5)solve the measure of pqsr
Answers
Answer:
See solutions below
Step-by-step explanation:
1) From the diagram QS = RS
3x = 2x+2
3x-2x = 2
x = 2
Since RS = 2x+2
RS = 2(2)+2
RS = 4 + 2
RS = 6
2) RQ = RS + QS
RQ = 2x+2 + 3x
RQ = 5x+2
RQ = 5(2)+2
RQ = 12
3) PQ = PR
3y-1 = y+5
3y-y = 5+1
2y = 6
y = 3
PQ = 3y-1
PQ = 3(3)-1
PQ = 8
4) PR = y+5
PR = 3+5
PR = 8
5) PQSR = PQ + QR
PQSR = 8 + 12
PQSR= 20

wanda spent 4 1/8 hours studying last night. She spent 1/3 of the time studying math. How much time did she spend studying math?
ANSWER PLSS
Answers
Answer:
[tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes
Step-by-step explanation:
Wanda spends a third of her [tex]4\frac{1}{8}[/tex] hours studying math. Let us multiply these two fractions to find how much time she spent. Our first step would be to convert the mixed number into an improper fraction, as mixed numbers are hard to manipulate with:
[tex]4\frac{1}{8} =\\\frac{33}{8}[/tex]
Now let us multiply:
[tex]\frac{1}{3} *\frac{33}{8} =\\\frac{11}{8}[/tex]
If we wish, we can convert this into a mixed number:
[tex]\frac{11}{8}= \\1\frac{3}{8}[/tex]
or, 1 hour and 22.5 minutes.
Therefore, Wanda spent [tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes studying math.

a bag contains 12 red 3 blue 6 green and 4 yellow marbles if a marble is drawn from the bag at random, what is the probability that the marble will be either blue or yellow
Answers
Answer:
7/25
Step-by-step explanation:
Probability = # of favorable outcomes / # of possible outcomes
Favorable outcomes = # of blue and yellow marbles
There are 3 yellow marbles and 4 blue marbles
There are 7 blue and yellow marbles so the favorable outcome is 7
Possible outcomes = total number of marbles
12 + 3 + 6 + 4 = 25
There are a total of 25 marbles
So possible outcomes = 25
If probability= favorable outcomes / possible outcomes then the probability of pulling a blue or yellow marble is 7/25

I've rearranged the tiles in the proper order
===================================================
Explanation
For step 2, we rewrite each expression in terms of sines and/or cosines. For instance, tan = sin/cos.
In step 3, we focus on the stuff in the numerator only. So we focus on sin/cos+cos/sin. In this step, we multiply top and bottom of the first fraction by sine. We multiply top and bottom of the second fraction by cos. These steps are done to get the LCD.
In step 4, we are able to add the fractions because both fractions have the same denominator.
In step 5, we use the pythagorean trig identity sin^2+cos^2 = 1.
In step 6, we use the idea that (A/B) divide by (C/D) = (A/B)*(D/C).
