Answer:

A. 27

Step-by-step explanation:

There are 40 students and 90% of them take exams

(40 students) * (0.9) = 36 students took exams

Of those 36 students, 75% (or 3/4) of them passed. Assuming passing exams means graduating:

(36 students) * (0.75 ) = 27 students graduated

Jack is trying to make extra money on his summer vacation from school. He works two different jobs, earning $9 per hour washing

Sveta_85 [38]

Answer:

$57

$9w+6d$

Step-by-step explanation:

Given that:

Earnings per hour for washing cars = $9

Earnings per hour for walking dogs = $6

Number of hours for which car washing is done = $w$

Number of hours taken for walking dogs = $d$

Earnings for $w$ hours for washing cars = Per hour earnings multiplied by number of hours = $9 $w$

Earnings for $d$ hours for walking dogs = Per hour earnings multiplied by number of hours = $6 $d$

Total earnings by both = $( $9w+6d$ )

Now, given that

Number of hours spent washing cars = 5 hours

Number of hours spent walking dogs = 2 hours

Therefore, total earnings by both = 9 $\times$ 5 + 6 $\times$ 2 = $57

ILL GIVE U STUFFFFF PLZZZZZZZZZZZ ANSWER ITTTTTTTTT

Answer:

Slope: $-\frac{3}{4}$

Y-intercept: 399

Slope-intercept form: $y=-\frac{3}{4}x+399$

Step-by-step explanation:

1. The equation in Standard form is given in the problem:

$3y+4y=1596$

2. Then, to write the equation of the line in slope-intercept form $y=mx+b$ , where m is the slope and b is the y-intercept, you must solve for y as you can see below:

$4y=-3x+1596\\y=\frac{-3x+1596}{4}\\y=-\frac{3}{4}x+399$

3. Therefore, the slope and the y-intercept are:

$m=-\frac{3}{4}\\b=399$
