\mathsf\blue{♧ANSWER♧}

Area = length × width

\mathsf \green{4 \frac{1}{2}  \times 2 \frac{1}{4} }

\orange \implies \mathsf \green{ \frac{9}{2}  \times  \frac{9}{4} }

\orange \implies \mathsf \green{ \frac{81}{8}  = 10.125}

\mathsf \blue{10.125  \: square \: units}

Let's call the Ameri-Mobile activation fee A, and the Cell-U-Later activation fee B.
Let's call the Ameri-Mobile monthly payment c, and the monthly Cell-U-Later monthly payment d
Let's call n the number of months

The cost of the Ameri-Mobile (in business, that's often called "total cost of ownership) is then:
(a + c * n)
<em>The cost of the plan after n months is the activation fee, plus each monthly payment times the number of months paid</em>
The cost of Cell-U-Later is, similarly:
(b + d * n)

You can even find out how many months you'd need to keep the plan for each plan to be equal (the longer you keep the plan, the better is the Cell-U-Later plan, because the activation fee distributes across a higher number of months), by plugging in numbers and solving this equation for n (but that's a bit more advanced):
a + c*n = b + d* n

Two perpendicular lines intersect on the y -axis. The equation of one line is x + 4y - 24 = 0 . Determine the equation of the ot
STALIN [3.7K]
Intersecting on the y axis means x=0.
Plug x=0 in the equation to find out the y value of the intercept> 0+4y-24=0, y=6
so the both line passes the point (0,6)

two perpendicular lines have slopes that are negative reciprocals of each other, that is, if one slope is a/b, the other is -b/a

In this case, the line x+4y-24=0, 4y=-x+24, y=-1/4 x + 6, the slope is -1/4, so the slope of the perpendicular line is 4/1.

the equation is y=4x+6

Second to last question, Find I<br> 50 points
ahrayia [7]

Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.

Remember: SOH-CAH-TOA

Looking from angle I, we know the opposite side and the hypotenuse. Therefore, we should use sine.

sin(I) = \frac{\sqrt{39}}{\sqrt{51}}

To solve, you can use your calculator and the inverse sine function (sin^-1).

I = sin^-1(\frac{\sqrt{39}}{\sqrt{51}})

I = 61 degrees

Hope this helps!
