Answer:
Step-by-step explanation:
y in (-oo:+oo)
(1/3)*y = 15 // - 15
(1/3)*y-15 = 0
1/3*y-15 = 0 // + 15

if mr.s rivas has 256 donust and she needs to give the same amount of dounts to her 5 freinds
Answers
Answer:
256/5=51.2
Step-by-step explanation:
Answer:
51 with a remainder of one, or 51.2
Step-by-step explanation:
She has 256 donuts and 5 friends. I assume this is for long division practice, so I will do long division.
5 | 256
Look at the first term. Does 5 go into 2? No. Bring down the next term.
5|256
25
Does 5 go into 25? Yes! How many times? 5. The first digit of our answer will be 5.
5|256 = 5
25
Now to get rid of the 25, we multiply the number we took for our answer by the divisor. 5x5 = 25. Subtract this from 25 and bring down the next (and last term).
5|256 = 5
25
-25
06
Does 5 go into 6? Yes. One time. Repeat what we did just now with this term now.
5|256 = 51
06
-5
1
Does 5 go into 1? No, it is smaller. Therefore we have a remainder of one donut.
If we are trying to divide ALL of the donuts equally, we will have to cut up the donut into 5 equal pieces. They would each be 1/5 of the donut, or 0.2.
So adding this, each friend would get 51 donuts, with an extra donut for Mrs Rivas, or each friend would get 51.2/51 and 1/5 donuts.
DOGS During a recent visit to the veterinarian's office, Mrs. Cho was informed that a healthy weight for her cat is approximately 35 pounds, plus or minus three pounds. Write an absolute value inequality that represents healthy weights w for her dog.
Answers
Answer:
Step-by-step explanation:
from the given information:
The healthy weight of the cat = 35 pounds
with +/- 3
To write the absolute value;
The healthy weight will either be less or greater.
So; w > 35 +3 or w < 35 - 3
w - 35 > 3 or w - 35 < -3
Thus, the healthy weight will be |w - 35| > 3

using compound interest, how long does it take to double a 1000 dollar investment that pays 6.5% annual interest, compounded monthly?
Answers
Answer:
11 years approx
Step-by-step explanation:
Given data
P=$1000
A=2000
R=6.5%
T= ?
Calculate time, solve for t
t = ln(A/P) / r
substitute
t=ln(2000/1000)/0.065
t=ln(2)/0.065
t=0.693/0.065
t=10.66
Hence the time is 11 years approx

Answers
Answ er:
-2, 3
Step-b y-step explanation:
The question is asking what x equals that makes y equals 0
How do we do this?
Because we're multiplying things together we just need one part of the equation to equal 0
for example if x= -2 then we would have the following
(-2+2)(-2-3)^2
(0)(-5)^2
which is 0
and the other answer is 3 because when you have
x-3=0
x= 3

If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. Since the decimal is going right, the exponent will be positive
