Answers

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.

What is the percent increase from 50 to 69

Answers

Detailed answer:
A change from 50 to 69 represents a positive change (increase) of 38%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old
|Old|
× 100%
Percent change = 69 - 50
|50|
× 100% =
19
50
× 100 = 38% (increase)
Where: 50 is the old value and 69 is the new value. In this case we have a positive change (increase) of 38 percent because the new value is greater than the old value.
This is a simple feat to figure out.

First find the difference between 69 and 50.

69 - 50 = 19


Now to find the decimal, divide 19 by 50 which would equal 0.38. And to find the percentage, move the decimal two spaces to the right.


Answer: 38%

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!



Answers

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?

Answers

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

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?

Answers

2 drinks! Can I pls have brainliest??

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.

b) Solve the equation and find out how many bags he can make:

Answers

Answer:

Dave invested approximately $29,629.63 into Oil companies.

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

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?​

Answers

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
