In ∆PQR, m P = 60°, m Q = 30°, and m R = 90°. Which of the following statements about ∆PQR are true? Check all that apply.
A. PQ = √3 • PR
B. PQ = 2 • PR
C. QR = 2 • PR
D. QR = √3/2 • PQ
E. QR = √3 • PR
F. PR = √3/2 • PQ
Answer:
C. QR = 2 • PR
Step-by-step explanation:
According to given information we can draw a right triangle with angle measures as follows :
30-60-90 and for this special right triangle the side length would follow as:
The side length that sees angle measure 30 = a
The side length that sees angle measure 60 = a[tex]\sqrt{3}[/tex]
The side length that sees angle measure 90 = 2a
following this information the:
PR(sees 30 degrees) = a (can be represented as PR in this case)
and so
QR(sees 90 degrees) = 2a (2*PR in this case)
PQ(sees 60 degrees) = a[tex]\sqrt{3}[/tex] ([tex]\sqrt{3}[/tex] *PQ in this case)
The correct option is C. QR = 2 • PR

Your grandfather placed $5,000 in a trust fund for you. In 12 years, the fund will be
worth $10,000. What is the rate of return on the trust fund?
Answer:
fv/pv=(1+r)^n
10,000/5000=(1+r%)^12
2=(1+r%)^12
r= 5.95
Step-by-step explanation:
fv/pv=(1 + r)^n
10000/5000=(1 + r%)^12
2=(1 + r%)^12
r=5.95

2. rx + h = -k
solve for x?
Answer:
x=(-k-h)/r
Step-by-step explanation:
rx+h=-k
subtract h from both sides.
rx=-k-h
divide both sides by r.
x=(-k-h)/r
Vivi steps off a 10-foot-high diving board and goes 7 3/8 feet below the surface of the swimming pool, then back up to the surface. How far does she travel altogether
Answer:
Your answer is 24 3/4 if you want it decimal wise it would be 24.75
Step-by-step explanation:
Well, let's set up our equation first. 10 (she jumped down 10 feet) + 2(7 3/8) (we are multiplying this by 2 because she first went under the surface then went back up to the surface)
Since distance is never negative you won't add any negative symbols, you'll simply add. First 2(7 3/8) = 59/4 or 14 3/4 | Next we add 10 to it 14+10 = 24 3/4
Your answer is 24 3/4 if you want it decimal wise it would be 24.75

Solve for w.
–1.01 = 1.4(w + 2) − 2.41
I SWEAR TO GOD PLEASE SOME ANSWER
Answer:
w= -1
Step-by-step explanation:
-1.01 = 1.4(w + 2) - 2.41
add 2.41 to both sides
1.4 = 1.4(w + 2)
divide by 1.4 on both sides
1=w+2
subtract 2 on both sides
-1 =w

5. What number is in the ones place of a product of 10 and
another number? Explain.
A product of 10 has a number in one's position, and another figure will be 0.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
The one number is 10.
And let the other number of two digits will be xy.
Then the product of 10 and another number will be
10 × xy = xy0
The number at ones place when the product of 10 and another number will be 0.

Answer:
I believe your missing part of the question.
Looking for the answer for the second one
Answer:
3 for the left one, and 5 on the right one.
Step-by-step explanation:
The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)
If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.
If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.

fill the table using this function rule
y=-10x+3
Answer:
53, 13, 3, -7
Step-by-step explanation:
When x = -5,
y = -10(-5) + 3
= 50 +3
= 53
When x = -1,
y = -10(-1) + 3
= -10 + 3
= 13
When x = 0,
y = 3
When x = 1,
y = -10(1) + 3
= -7

How to give a fraction of an hour

Step-by-step explanation:
Lucy has read 500 pages of her summer reading assesment, and Angie has read 460 pages. Lucy has reads 10 per week for the remainder of the summer, and Angie reads 20 pages per week for the remainder of the summer. Write and solve an equation to show how many weeks it will take before the girls have read the same amount of pages.
Answer:
It would take four more weeks before the two read the same number of pages.
Step-by-step explanation:
Let [tex]x[/tex] denote the number of extra weeks required before the two read the same number of pages.
Express the number of pages each would read between now and [tex]x[/tex] weeks into the future:
Lucy reads [tex]10[/tex] pages per week. Thus, she would have read [tex]10\, x[/tex] additional pages after [tex]x[/tex] more weeks.
Angie reads [tex]20[/tex] pages per week. She would've read [tex]20\, x[/tex] additional pages after [tex]x[/tex] more weeks.
It is also given that Lucy has already read [tex]500[/tex] pages. After reading [tex]10\, x[/tex] pages in the upcoming [tex]x[/tex] weeks, Lucy would have read a total of [tex](500 + 10\, x)[/tex] pages.
Likewise, after reading [tex]20\, x[/tex] pages in the upcoming [tex]x[/tex] weeks, Angie would have read a total of [tex](460 + 20\, x)[/tex] pages.
It is assumed that the two would have read the same number of pages after these [tex]x[/tex] more weeks. In other words:
[tex]500 + 10\, x = 460 + 20\, x[/tex].
Solve this equation for [tex]x[/tex]:
[tex]x = 4[/tex].
In other words, Lucy and Angie would have read the same number of pages after four more weeks.
