Mitchell buys a $1,400 dryer with an installment plan that requires 17% down. How much is the down payment?
Hunter-Best [27]

The amount of down payment Michelle paid for a dryer of $1,400 at 17% down payment is $238

Given:

Total cost of dryer = $1,400

down payment percentage = 17%

<em>Amount paid for down payment</em> = 17% of $1,400

= 17/100 × 1400

= 0.17 × 1400

= $238

Therefore, the amount of down payment Michelle paid for a dryer of $1,400 at 17% down payment is $238

Answer:

<h2>53°</h2>

solution,

Sum of exterior angle of polygon=360°

3x - 5 + 2x + 10 + 90 = 360 \\ or \: 3x + 2x - 5 + 10 + 90 = 360 \\ or \: 5x + 5 + 90 = 360 \\ or \: 5x  + 95 = 360 \\ or \: 5x = 360 - 95 \\ or \: 5x = 265 \\ or \: x =  \frac{265}{5}  \\ x = 53

Hope this helps...

Transform the Cartesian (rectangular) equation to a polar equation: x = -9. The selected answer is incorrect.
nika2105 [10]

Answer:

Solution : Option C

Step-by-step explanation:

We have the equations r² = x² + y², x = r cos(θ), and y = r sin(θ) that can be used to solve this problem. In this case we only need the second two equations (  x = r cos(θ), and y = r sin(θ) ) as we don't need to apply the concept of circles etc here.

Given : x = - 9,

( Substitute r cos(θ) for x )

r cos(θ) = - 9,

r = - 9 / cos(θ)

( Remember that sec is the reciprocal of cos(θ). Substitute sec for 1 / cos(θ) )

r = - 9 sec(θ)

Therefore the third option is the correct solution.
