Maurice took out an auto loan of $3200 for 6 months. The
simple annual rate was 18%. How much interest did he pay
on his loan?
$3488

S3456
S600

7
8
9
10
Answer:
$288
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 18%/100 = 0.18 per year,
then, solving our equation
I = 3200 × 0.18 × 0.5 = 288
I = $ 288.00
The simple interest accumulated
on a principal of $ 3,200.00
at a rate of 18% per year
for 0.5 years is $ 288.00.

Determine whether the ordered pair is a solution of the linear inequality.
y > x - 1 ordered pair (0, 1)
Help would be appreciated! (Will give brainliest) Please don’t give me invalid answers on purpose :(
Thanks!
Answer:
Yes, (0, 1) is the solution of the given inequality.
Step-by-step explanation:
To find whether the given ordered pair is a solution of the linear inequality, we will satisfy the inequality with the coordinates of the ordered pair.
If the inequality is true for the ordered pair it will be the solution.
Inequality is,
y > x - 1
For (0, 1),
1 > 0 - 1
1 > -1
True.
Therefore, ordered pair (0, 1) is the solution of the given inequality.
Mr. Jones has a new car. The manufacturer says that the car should get about 28 miles per gallon in the city. About how many miles can Mr. Jones drive on 11.5 gallons of gas? At 2.89 per gallon, how much would that cost?
Answer:a) 322 MILES B) 34.391 ( The price per gallon was not given in units ) but if price of I gallon = lets say $2.89, then for 11.5 Gallons will be $34.391
Step-by-step explanation:
a)
M r Jones car needs 28 miles for 1 gallon = 28 MILES= 1 Gallon
Number of miles he can drive withe 11.5 gallons
1 Gallon = 28 miles
11.5 gallons = 11.5 x 28miles = 322 miles
b) IF 1 gallon costs 2.89
11.5 gallons will cost= 11.5 x 2.89= 34.391

Dixie drinks 1/3 a cup of water in 1/6 of a minute. How many cups of water per minute does Dixie drink?
Hello, 928747! I can help.
So, we're trying to find out how many cups of water Dixie can drink per minute.
Since there are 60 seconds in a minute, we can assume that 1/6 of a minute is 10 seconds
1/6 = 10/60
So there are 60 seconds in a minute so we would multiply 1/3 by 6 to find how many cups she can drink in one minute
1/3 x 6 = 2
So, Dixie can drink 2 cups in one minute.

Dave took 8/9 of his savings and decided to invest it. With his investments, 2/3 of it will go into the Canadian stock market. Amongst his Canadian stocks, 1/2 of it will be invested into oil companies. If Dave had $100,000 in his savings account, how much did he invest into Oil companies?
a) Write an equation to represent the scenario
b) Solve the equation and find out how many bags he can make:
Answer:
Dave invested approximately $29,629.63 into Oil companies.
Step-by-step explanation:
8/9 (100,000) = i
i= $88,888.89
2/3(88,888.89)=c
c = $29,259.26
1/2(29,259.26)=o
o= $29,629.63

A company makes 110 bags.
46 of the bags have buttons but no zips.
20 of the bags have zips but no buttons.
39 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?
Answer:
51/110
Step-by-step explanation:
No: of bags with buttons but no zips = 46
No: of bags that have both buttons and zipz = 110-(46+20+39) = 5
No: of bags with buttons = 46+ 5 = 51
Total no: of bags = 110
Probabilty = 51/110
