Heres how I did it. I used my fingers for this, it's a little odd I know but it works. I put up one finger for each half. So each finger represents one half. I needed to get to 2 1/2 so I put up two finger and I said "that's one " because a half plus a half is a whole or just one. Then I put up one more finger and I said " That's one and a half". I then put up two more and then I had 2 1/5. What I did then was count how many fingers I had up. I had 5 fingers up. So then I multiplied 3 x 5 and that gave me 15. Hope I could help!

How is an exponential growth function of the form f(x)=a(1+r)^x related to an exponential function of the form f(x)=a*b^x?
A.
The value of a is the growth factor, and b is equal to the initial amount r.
B.
The value of a is the growth factor, and b is equal to the initial amount (1+r).
C.
The value of a is the initial amount, and b is equal to the growth factor (1+r).
D.
The value of a is the initial amount, and b is equal to the growth factor r.
The true statement is (c) the value of a is the initial amount, and b is equal to the growth factor (1+r).
How to compare the functions?The functions are given as:
f(x) = a(1 + r)^x
f(x) = a * b^x
An exponential growth function is represented as:
y = ab^x
Where
a represents the initial valueb represents the rateBy comparison:
b = 1 + r
Hence, the true statement is (c) the value of a is the initial amount, and b is equal to the growth factor (1+r).

3,000 pounds of sand is usede to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes. how much sand can be put in each of the smaller sandboxes?
The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.
What is division?Division is breaking a number up into an equal number of parts.
Given that, 3,000 pounds of sand is used to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes.
Amount left after filling the larger box = 3000-1000 = 2000 pounds
To find the equal amount of sand to be filled in 4 smaller boxes, we will divide the amount left to the number of boxes.
= 2000/4
= 500
Hence, The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.

Find the value of n.
(-y + 5.3) + (7.2y - 9) = 6.2y + n
Transfer 6.2y to the other side and change its sign.
(-y + 5.3) + (7.2y - 9) - 6.2y = n
Solve for the value of n.
-y + 5.3 + 7.2y - 9 - 6.2y = n
group like terms
-y + 7.2y - 6.2y + 5.3 - 9 = n
0 + (-3.7) = n
-3.7 = n
Substitute n with its value.
(-y + 5.3) + (7.2y - 9) = 6.2y + n
(-y + 5.3) + (7.2y - 9) = 6.2y + (-3.7)
-y + 5.3 + 7.2y - 9 = 6.2y - 3.7
Group like terms
-y + 7.2y + 5.3 - 9 = 6.2y - 3.7
6.2y - 3.7 = 6.2y - 3.7

A. Likely
B. unlikely
C. as likely as not
D. impossible
F. certain
Answer:
A. likely
Step-by-step explanation:
There are 6 outcomes 1, 2, 3, 4, 5 and 6.
Numbers less than 6 are 1, 2, 3, 4 and 5.
So the chance to roll a number less than 6 is 5/6, which has a probability of likely as there are more chances to roll a number less than 6

===============================================
Explanation:
We have a 5 by 3 grid of letters. There are 5*3 = 15 letters total.
Of that total, there are 5 vowels (2 'e's in row 1, 2 'e's in row 2, and 1 'e' in row 3)
So there are 15-5 = 10 consonants.
The probability of pulling out a consonant is 10/15 = 2/3
After selecting that consonant, we have 10-1 = 9 consonants left out of 15-1 = 14 letters total.
The probability of selecting a second consonant, after not replacing the first selection, is 9/14.
Multiply the two fractions found:
(2/3)*(9/14) = (2*9)/(3*14) = 18/42 = 3/7
To reduce 18/42, we divide both parts by the GCF 6, which is how we end up with 3/7.
