B.12.65
C.12.6
D.12.66
pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

Number of red marbles=4
Number of blue marbles=3
P(B)=3/10
P(R)=4/10=2/5
Total number of marbles=10
Answer:
The number of red marbles is 4. The number of blue marbles is 3. The total number of marbles is 10 because 4+3+3 is 10. P(red) is 2/5 because there are 10 total marbles and there are 4 marbles which is equal to 4/10 marbles are red, and you simplify 4/10 to 2/5. P(blue) is 3/10 because there are 3 blue marbles out of 10 marbles.

Answers
Answer:
70 degrees
Step-by-step explanation:
2x+3x-20+x+20=180
( angles in a triangle add up to 180 degrees)
as you want to find one x you need to move everything else to the other side: first collect all the like terms: 6x=180
in order to find x you need to divide 180 by 6 which is equal to 30
therefore x=30
if you substitute this into XYZ it would be: 3(30)-20
90-20=70
therefore XYZ=70 degrees
Hope this helped
Answer:
70
Step-by-step explanation:
So we know that the angles of a triangle equal up to 180 degrees. So let's make an equation. So we can do:
2x+(3x-20)+(x+20) = 180
Simplify:
6x=180
x=30
We can also plug this in to check our work. So it would be:
60+(90-20)+(30+20)
simplify
70+50+60=180
Then we have to find angle XYZ so we do 90-20=70

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)

cannot be simplified any further because

do not have any common factors.
9

also cannot be simplified any further for the same reason - this means that the two ratios we had are already in simplest form.

Chantelle takes out a loan of $3,500 with an APR of 4.25%. She will repay the loan in monthly payments for 6 months. To find the total amount of interest she will pay, Chantelle uses an online calculator. What are the correct numbers she should enter?
Answers
Answer:
P = 3,500 r = 0.0425 n = 12 t = 0.5
Step-by-step explanation:
P is the principal amount, which in this case is $3,500, or the start amount.
r is the interest rate, which is 4.25%. Change 4.5% to decimal form and it will be 0.0425.
n is the number of times the loan is repaid, or 12.
t is the time. In this case, the loan will be for 6 months, or half a year. Remember that variable t is always in term of years. In decimal form, half a year is 0.5.

D:
x=0.1,0.3,25,100
y=200,40,0.8,0.2
Answers
Answer:
A, C
Step-by-step explanation:
If it is inversely proportional then y = k/x
Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)
A.
6 = k/1 (k=6)
3 = k/2 (k=6)
2 = k/3 (k=6)
1.5 = k/4 (k=6)
Yes! It's the same everywhere so this is correct!
B.
7.5 = k/2 (k=15)
5 = k/3 (k=15)
3 = k/5 (k=15)
2 = k/7 (k=14)
For the last one k is not the same so nope. It is wrong.
C.
24 = k/1 (k=24)
8 = k/3 (k=24)
k = 6×4 = 24
k = 24×1 = 24
This is correct too.
D.
k = 0.1×200 = 20
k = 0.3×40 = 12
k = 0.8 × 25 = 20
We can already see that k is not the same everywhere.
Only A and C, x and y are inversely proportional for all of the values

Step-by-step explanation:
those three answers add up to 2x+5
Answer:
Option (A), (D), (F)
Step-by-step explanation:
Option (A) = 2x + 5
Option (D) = 4x + 11 - 2x - 6
Option (F) = 2x - x + 3 + x - 3 + 5
Now let’s Prove this statement.
(A) = 2x + 5
= 2x + 5
(D) = 4x + 11 - 2x - 6
= 4x - 2x + 11 - 6
= 2x + 5
(F) = 2x - x + 3 + x - 3 + 5
= 2x - x + x + 3 - 3 + 5
= x + x + 5
= 2x + 5
As we can see that all the 3 equations give the same result as 2x + 5
Hence we can prove that Option (A), (D), (F) are all equal.
