Answer:
RT=108
Step-by-step explanation:
Consider ΔQST:
Use pythagorus's theorem.
a²=b²+c²
QS²=QT²+ST²
53²=QT²+28²
2809-784=QT²
QT=√2025=45
Consider ΔQRT:
Use pythagorus's theorem.
a²=b²+c²
QR²=QT²+RT²
117²=45²+RT²
13689-2025=RT²
RT=√11664=108

If cos θ > 0, which quadrant(s) could the terminal side of θ lie?
Answer:
I and IV
Step-by-step explanation:
cosine is positive/greater than 0 in quadrants I and IV. Its just a rule of the unit circle.
Can remember by All Star Trig Class
meaning all the trig funtions are positive in quadrant I
sin is positive in II
tan is positive in III
and cos is positive in IV

3f^4g^3 x 8fg^4 / (6f^2g^3)^2 how do you do this? I know the answer is 2/3fg but how do you get 0.666... into that fraction form?
9514 1404 393
Answer:
0.666... = 6/9 = 2/3
Step-by-step explanation:
The repeating decimal 0.666... can be turned to a fraction as follows.
Let x represent the value of the number. Then 10x is ...
10x = 10(0.666...) = 6.666...
Subtracting x gives ...
10x -x = 6.666... - 0.666... = 6.000...
9x = 6
Dividing by 9 and simplifying, we have ...
x = 6/9 = 2/3
__
It can be worthwhile to remember that 1/9 = 0.111... repeating.
Then 3/9 = 1/3 = 3(0.111...) = 0.333... repeating
and 6/9 = 2/3 = 6(0.111...) = 0.666... repeating
Most calculators will round the last digit of 2/3 so that it is a 7. So, you may see ...
2 ÷ 3 = 0.6666667 or 0.66666666667
or something similar, depending on your calculator. It is up to you to recognize this as probably a representation of 2/3. Some calculators will display the number as a fraction, so you don't have to guess.
_____
Additional comment
A similar method is used to convert repeating decimals of other lengths to fractions. In general you multiply by 10^n, where n is the number of repeating digits. Then proceed as above: subtract x, divide by the coefficient of x. You will find you are always dividing by a number that has as many 9's as there are repeating digits.
Mr. Robison rides 136 miles per hour on his bike ride. He wants to ride more than 360 miles at the same rate during his next bike ride. Which inequality represents all possible values for b, the number of hours Mr. Robison must bike to ride more than 360 miles rounded to the nearest hundredths?
Answer: See explanation
Step-by-step explanation:
From the equation, we are informed that Mr. Robison rides 136 miles per hour on his bike ride and that he wants to ride more than 360 miles at the same rate during his next bike ride.
The inequality that represents all possible values for b, the number of hours Mr. Robison must bike will be:
136b > 360
b > 360/136
b > 2.65
Therefore, Me Robinson must bike for more than 2.65 hours

3(-4+4)+5n=2n what are the steps for finding n
Answer:
1. Move the variables to one side: 3(-4+4) = -3n
2. Distribute. You will end up with 0 = -3n
3. Divide both sides by -3. n = 0
Step-by-step explanation:
Answer:
n=0
Step-by-step explanation:
3(-4+4)+5n=2n
first distribute
-12+12+5n=2n
combine like terms
5n=2n
subtract 2n on both sides
3n=0
divide by 3 on both sides
n=0/3
which is also equal to
n=0

Peter makes a base monthly salary of $2,500. As a vendor, he must sell $15,000 worth of items per month. He also makes an 18% commission on all sales beyond the monthly quota. If Peter sold $24,600 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?
Answer:
Monthly salary= $4,228
Step-by-step explanation:
Giving the following information:
Fixed salary= $2,500
Sales commission= 10%
Sales= $24,600
To calculate the monthly salary, we need to use the following formula:
Monthly salary= fixed income + commission
Commission= (24,600 - 15,000)*0.18
Commission= $1,728
Monthly salary= 2,500 + 1,728
Monthly salary= $4,228
Melissa earns $180 a week selling shoes plus a commission of $10 each pair of shoes she sells. How
many pairs of shoes must she sell to make a minimum of $500 a week?
Step-by-step explanation:
10X+ 180= 500
10X= 500-180
10X= 320. .....divine both sides by 10 to solve for X
X = 32.
check
10(32)+180 = 500
320+180 =500
500 =500...confirmed

Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts and uses 2 of the pieces on gifts.How much ribbon does she use ? Solve this problem any way you choose.
Answer: 6 2/3
Step-by-step explanation:
Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts. This means that each ribbon will be:
= 10/3
= 3 1/3
She then uses 2 of the pieces on gifts. The amount of ribbon that she use will be:
= 3 1/3 × 2
= 10/3 × 2
= 20/3
= 6 2/3

Can someone please help me? 3t + 7 = -8
Answer:
Step-by-step explanation:
Look at 3%2At%2B7=%28+-8+%29.
Moved these terms to the left %28 +8+ %29
It becomes 3%2At%2B7%2B _green%28+8+%29=0.
Look at 3%2At%2B_red%28+7+%29%2_red%28+8+%29=0.
Added fractions or integers together
It becomes 3%2At% 2B % 28+15+%29=0.
Look at highlight_red%28+3%2At%2B15+%29=0.
Solved linear equation %28+3%2At%2B15=0+%29 equivalent to 3*t+15 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: t=-5.
Answer: t= -1/3
Step-by-step explanation:
3t+7=-8
subtract 7 from 7 and 8 (this cancels out the 7)
left with 3t = -1
divide 3 into 3t and -1
the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3

Answer:
x=10, x=-2
Step-by-step explanation:
x^2-5x-3x+15=35
x^2-8x-20=0
Multiply to -20, add to -8: -10, 2
(x-10)(x+2)=0
x=10, x=-2
Answer:
x = −2 or x = 10
Step-by-step explanation:
(x - 3)(x - 5) = 35
x^2 − 8x + 15 = 35
x^2 − 8x + 15 − 35 = 35 − 35
x^2 − 8x − 20 = 0
(x+2)(x−10) = 0
x + 2 = 0 or x − 10 = 0
x = −2 or x = 10

Write an explicit formula for the nth term of this sequence:
6, 11, 16, 21, . . .
1. an=5n+11
2. an=5n+1
3. an=21-5n
4. an=6n+1
Answer:
2)an = 5n + 1
Step-by-step explanation:
This is an arithmetic series.
6 , 11 , 16, 21 ,.....
First term = [tex]a_{1}[/tex] = 6
Common difference = d = second term - first term
= 11 - 6 = 5
nth term = [tex]a_{1}+(n-1)*d[/tex]
= 6 + (n - 1) * 5
= 6 + n * 5 - 1*5
= 6 +5n - 5
= 6 - 5 + 5n
= 1 + 5n
