The x-intercept shows that you can buy short-sleeve shirts and long-sleeve shirts. The y-intercept shows that you can buy long-s
Sergeu [11.5K]

Question:

You are ordering short-sleeve shirts (x) for $10 and long-sleeve shirts (y) for $15. Your budget is $300. Write the equation and find the intercepts.

Interpret their meaning.

Answer:

The x-intercept shows that you can buy 30 short-sleeve shirts and 0 long-sleeve shirts.

The y-intercept shows that you can buy 20 long-sleeve shirts and 0 short-sleeve shirts.

Step-by-step explanation:

Given

$10 per short sleeve

$15 per long sleeve

Budget = $300

The above can be represented as:

Total Cost of Short Sleeve + Total Cost of Long Sleeve = Budget

i.e.

10 * x + 15 * y =300

10x + 15y =300

To solve for the y intercept, we set x to 0

10 * 0 + 15y =300

15y =300

Divide through by 15

y = 20

<em>This implies that, you can buy 0 short sleeves and 20 long sleeves</em>

To solve for the x intercept, we set y to 0

10x + 15 * 0 = 300

10x  = 300

Divide through by 10

x = 30

<em>This implies that, you can buy 0 long sleeves and 30 short sleeves</em>

A right triangle has one angle that measure 23o. The adjacent leg measures 27.6 cm and the hypotenuse measures 30 cm. What is th
Mnenie [13.5K]
First, we need to find the opposite side.
opposite^2 = 30^2 -27.6^2
opposite^2 = 900 -761.76
opposite^2 = 138.24
opposite side = <span> <span> <span> 11.7575507654 </span> </span> </span>

Right Triangle Area = (adj * opp) / 2
Right Triangle Area = (27.6 * 11.758) / 2
Right Triangle Area = 324.51 / 2
Right Triangle Area = 162.25

Answer is 161.7 cm^2
