The cost of bathing service per dog :
$324/27 = $12
x = <span>number of dogs she washes
</span>y = revenue
so the equation:
y = 12x
1 dog = $12
2 dogs = $12 x 2 = $24
3 dogs = $12 x 3 = $36
4 dogs = $12 x 4 = $48
use these coordinate points to graph it.
x - coordinate = <span>number of dogs she washes
</span>y - coordinate = total cost ($)
Answer:
Step-by-step explanation:
-12+5x=-24+x
4x=-12
x=-3
Answer:
B) 54
Step-by-step explanation:
A mode of a number set is the number the appears the most.
In the list given, 54 was the number that appeared the most.
Answer:
39.5 ft
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between angles and sides of a right triangle.
Tan = Opposite/Adjacent
This lets us write two equations in two unknowns:
tan(67°) = AD/CD . . . . . . . . . . angle at guy point
tan(39°) = AD/(CD+32) . . . . . .angle 32' farther
__
Solving the first equation for CD and using that in the second equation, we can get an equation for AD, the height of the tower.
CD = AD/tan(67°)
tan(39°)(CD +32) = AD . . . . eliminate fractions in the second equation
tan(39°)(AD/tan(67°) +32) = AD
32·tan(39°) = AD(1 -tan(39°)/tan(67°)) . . . simplify, subtract left-side AD term
32·tan(39°)tan(67°)/(tan(67°) -tan(39°)) = AD . . . . divide by AD coefficient
AD ≈ 39.486 . . . . feet
The tower is about 39.5 feet high.
