Question isn't well formatted :

Actual question :

One day, River writes down the numbers 1,2,...,999. What is the sum of all the digits that River wrote down?

Answer:

499500

Step-by-step explanation:

Number written :

1, 2,...., 999

The interpretation of the number written is 1 up to 999

Hence, the sum of the number written is the addition of all the numbers from 1 up to 999

Using the python program :

sum = 0

for i in range(1000):

sum += i

print (sum)

Output = 499500

Answer:

13500

Step-by-step explanation:

Notice how it says the sum of all of the DIGITs. We have to add together the sum of the digits. We can do this by:

300(1 + 2 + 3 + 4.... + 9) = 300*45 = 13500

The inverse of the function is [tex]\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]

For a 2 by 2 matrix, the inverse is generally expressed as:

[tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] ^{-1}=\frac{1}{ad-bc}\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right][/tex]

Since the given matrix is a square matrix and 2 by 2, therefore it will have an inverse.

Determine the determinant

|A| = 5(5) - 2(12)

|A| = 25 - 24

|A| = 1

Substitute the values into the formula above

[tex]\left[\begin{array}{ccc}5&12\\2&5\\\end{array}\right] ^{-1}=(1)\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]

Hence the inverse of the function is [tex]\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]

Step-by-step explanation:

$2.40 ÷ 8 = 30 cents

Answer:

30 Cents per orange

Step-by-step explanation:

so 2.40/8 to x/1

it will then be 2.40x1 and 8x.

we divide 2.40 by 8 to get x by itself.

Then x = .3 so 30 cents. <3

Answer: a=19

Step-by-step explanation: In order to solve this question, we must first take out the parenthesis, we can do this by taking 1/3 and multiply it by a and 5. This will give us 8=1/3a+5/3, with this we can subtract 5/3 on both sides of the equation, which will then give us, 19/3=1/3a. Last, we can divide 19/3 by 1/3 giving us 19 as our final anwser. a=19

Answer:

19

Step-by-step explanation:

First distribute the 1/3 to the "a" and the 5, which leaves you with 8= 1/3a+ 5/3.

Then subtract 5/3 from both sides. 8-5/3, which solves out to 19/3= 1/3a. Now times both sides by 3/1 (the reciprocal of 1/3 to get it to cancel out) 19/3*3. The 3's cancel out and you are left with 19=a.

Answer:

x = 7

angle (7x + 8) = 57 degrees

Step-by-step explanation:

all triangles interior angles add up to 180 degrees.

(7x+8) + 90 + 33 = 180

7x+8 = 57

7x = 49

x = 7

(7x + 8) = 57

Answer:

57 degrees

Step-by-step explanation:

7x+8+33=90

7x=90-8-33

=90-41

7x=49

x=7

and it has a minimum

Step-by-step explanation:

Answer:

If Ron works 8 hours a day and get's paid $15 an hour

for 5 days a week and works for 12 weeks

1 hour = $15

8 hours = $120

So Ron get's paid $120 a day

So if he works 5 days a week then

120 x 5 = $600

Ron get's paid $600 a week

So if Ron works for 12 weeks then

600 x 12 = $7,200

Ron's gross pay is $7,200
