In Olongapo City, a bump car ride costs

1 answer:

7 0

Solve for n in 270=120 + n*10. 120 gives you first 30 minutes and n is the number of additional 10 minutes you ride. In this case you ride for 30+n*10 minutes. n = (270-120)/10 = 15. So the total time is 30+15*10 = 180 minutes. Or three hours!! That’s a lot of bumper cars!!

Answer:

x = 57/28

y = -95/84

z = 97/168

Step-by-step explanation:

Use the application in the next link: https://www.zweigmedia.com/RealWorld/tutorialsf1/scriptpivotold.html

Start with the expanded array:

$\left[\begin{array}{cccc}1&5&8&1\\3&2&2&5\\-2&-7&2&5\\\end{array}\right]$

then using the tool provided, make row operations until you find the solution:

r2 = r2-3r1

$\left[\begin{array}{cccc}1&5&8&1\\0&-13&-22&2\\-2&-7&2&5\\\end{array}\right]$

r3 = r3+2r1

$\left[\begin{array}{cccc}1&5&8&1\\0&-13&-22&2\\0&3&18&7\\\end{array}\right]$

r2 = r2*(-1/13)

$\left[\begin{array}{cccc}1&5&8&1\\0&1&22/13&-2/13\\0&3&18&7\\\end{array}\right]$

r1 = r1- r2*5

$\left[\begin{array}{cccc}1&0&-6/13&23/13\\0&1&22/13&-2/13\\0&3&18&7\\\end{array}\right]$

r3 = r3+ r2*-3

$\left[\begin{array}{cccc}1&0&-6/13&23/13\\0&1&22/13&-2/13\\0&0&168/13&97/13\\\end{array}\right]$

r3 = r3*13/168

$\left[\begin{array}{cccc}1&0&-6/13&23/13\\0&1&22/13&-2/13\\0&0&1&97/168\\\end{array}\right]$

r2 = r2- r3*22/13

$\left[\begin{array}{cccc}1&0&-6/13&23/13\\0&1&0&-95/84\\0&0&1&97/168\\\end{array}\right]$

r2 = r2+ r3*6/13

$\left[\begin{array}{cccc}1&0&0&57/28\\0&1&0&-95/84\\0&0&1&97/168\\\end{array}\right]$

Here you have a reduced array an therefore the answers to each variable are on each row:

$\left[\begin{array}{c}x\\y\\z\end{array}\right]$

EXPLAIN What is the quotient when 1,000,000,000 is divided by 28x 57

Rama09 [41]

Answer:

626,566.42

Step-by-step explanation:

The quotient is answer of a value divided by another value. In this problem we have a value of 1,000,000,000 divided by the product of 28 x 57.

This can be represented like this:

$Total=\dfrac{1,000,000,000}{28*57}$

$Total=\dfrac{1,000,000,000}{1,596}$

$Total=626,566.42$

The fraction can also be used to indicate a number being divided by another number.

Daniel [21]

Answer:

We have 8 more boys than girls on the swim team.

Step-by-step explanation:

The ratio of boys to girls on a swim team is represented as:

4 : 2

Total number of athletes is given as 24

Total ratio is given as:

4 + 2 = 6

Step 1

We find the number of boys and girls

Number of boys = 4/6 × 24 = 16 boys.

Number of girls = 2/6 × 24 = 8 girls.

Therefore, since we have 16 boys and 8 girls on the swim team, we have 8 more boys than girls on the swim team.
