25x + 4y is the total cost.

.06(25x+4y) is the total tax.
Rewrite using fractions then expand:

6/100 * (25x + 4y)
(150/100)x + (24/100)y
1.5x + .24y is the expression to find tax.

Answer:

h ≤ 124 / 9

h ≤ 13.78

Step-by-step explanation:

(3/4) (12h - 32) ≤ 100 (multiply both sides by 4)

(3) (12h - 32) ≤ 100 (4)

(3) (12h - 32) ≤ 400 (distribute 3 into the parenthesis)

(12h)(3) - (32)(3) ≤ 400 (expand left side terms)

36h - 96 ≤ 400 (add 96 to both sides)

36h ≤ 400 + 96

36h ≤ 496 (divide both sides by 36)

h ≤ 496 / 36 (sinmplify)

h ≤ 124 / 9

h ≤ 13.78

PilotLPTM [1.2K]

Answer:

The answer is " $\sin x=0.6$ "

Step-by-step explanation:

Please find the attached file of the graph.

Given:

$\to \sin x = 0.6\\\\\to x+y+90=180^{\circ} \\\\\to x+y=90^{\circ} \\\\\to y=90-x\\\\$

Let

$\to \cos y= \cos(90-x) =\sin x=0.6$

There are currently 450 kids the school population is expected to grow 4% next year how many total students do you predict there

scoray [572]

Next year there will be about 468 students, to get this answer you multiply 0.04 × 450 to get 18. You then add 18 to 450 to get 468.

Hope this helps!
