Answer:34.8 Million
Step-by-step explanation:
if y varies directly as x and y=32 when x=4. find the constant of variation
Answer:
k = 8
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 32 when x = 4, then
32 = 4k ( divide both sides by 4 )
8 = k
Solve the following problem:
5x - 3 = 4x + 3
A. x = 5
B. x = 6
C. x = 7
Answer:
x=6
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
5x−3−4x=4x+3−4x
x−3=3
Step 2: Add 3 to both sides.
x−3+3=3+3
x=6
Answer:
B.
Step-by-step explanation:
5x-3+3=4x+3+3
5x=4x+6
5x-4x=4x+6-4x
x=6

Find the measure of the indicated angle
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

PLEASE HELP 20 POINTS One day, River writes down the numbers $1,$ $2,$ $\dots,$ $999.$ What is the sum of all the digits that River wrote down?
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

Ron works 8 hours a day, 5 days a week, $15 dollars an hour, for 12 weeks.
What is his gross pay?
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

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

8=1/3(a+5)
What does a equal?
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.
I hope this helped! :)
