30 books on the shelf are Fiction.
Step-by-step explanation:
Hey!
There are 50 books on a shelf.
1/5 of the books are Science Fiction.3/10 are Non-Fiction.The Rest are Fiction.how many books on the shelf are Fiction?
==================================================================
MAKE AN EQUATION!
We know that there are three Categories: Fiction, Science Fiction, and Non Fiction.
Total- 50
⇒ 50 =
1/5 of 50 are SF
⇒ 50 = (1/5)(50)
3/10 of 50 are NF
⇒ 50 = (1/5)(50) + (3/10)(50) + x
--------------------------------------------------------------------------------------------------------------
SOLVE THE EQUATION!
(1/5)(50) + (3/10)(50) + x = 50
To Isolate X-
-Multiply and remove the parentheses..
⇒ 50/10 + 150/10 + x = 50
-Simplify.
⇒ 5 + 15 + x = 50
-Add Like Terms
⇒ 20 + x = 50
-Subtract 20 from both sides.
⇒ 20 + x - 20 = 50 - 20
-Simplify Right Hand Side.
⇒ x = 30
--------------------------------------------------------------------------------------------------------------
So, 30 books on the shelf are Fiction.

What is (-3, -14) and (0, -9) written in slope intercept form? Thank you!
Answers
Answer:
Y= 5/3x + -9
Step-by-step explanation:
Well its
y=mx+b
m is slope
B is y intercept
To fidn y intercept, just make sure the X value of any coordiante given is 0 and the y value is not 0. So basically anything with (0, y), thats your y intercept.
Slope Is just
(y2-y1) / (x2-x1)
Answer:
y = 5/3x - 9
The equation for slope-intercept form would be y = mx + b.
Where y would be the total, m would be the slope, and b would be the y-intercept.
Dani experimented with a dollar bill and the copy machine a dollar bills length is 6.1 inches and width is 2.6 inches, she reduced the dollar bill so its length was 80% of its original size. What is the length of the copy of the dollar bill? please show how you figured it out. NO LINKS
Answers
Answer:
The length of the copy of the dollar bill is 4.88 inches in length and 2.08 inches in width.
Step-by-step explanation:
If Dani wants to make a smaller copy of a dollar bill and reduce its size to 80%, you will need to multiply the dollar bills original length by 8%.
80% = 0.8
0.8 x 6.1 = 4.88
80% = 0.8
0.8 x 2.6 = 2.08

Garret invested $12,000 at an annual interest rate of 6%. How much money would Garret have had to invest at 10% so that the combined interest rate for both investments was 7% over the year?
Answers
Step-by-step explanation:
To determine how much money Garret would have had to invest at 10% in order to achieve a combined interest rate of 7% over the year, we can set up the following equation:
(12000 * 0.06) + (x * 0.10) = (12000 + x) * 0.07
Let's solve this equation to find the value of 'x', which represents the amount Garret would have had to invest at 10%:
720 + 0.10x = 0.07(12000 + x)
Simplifying the equation:
720 + 0.10x = 840 + 0.07x
0.10x - 0.07x = 840 - 720
0.03x = 120
x = 120 / 0.03
x = 4000
Therefore, Garret would have had to invest $4,000 at a 10% annual interest rate in order to achieve a combined interest rate of 7% over the year.

Volume = Bh
Volume = (1/2 x b x h) h
Volume = (1/2 x 6 x 4) 10
Volume = 120
SA = 2B + Ph
SA = 2(1/2 x b x h) + (s + s + s)h
SA = 2(1/2 x 6 x 4) + (5 + 5 +6) 10
SA = (24 + 16) 10
