Zuhalie needs to rent a racing bike. She is choosing between two rental options. Option A is $50 per month with a $200 down paym

Law Incorporation [45]

Answer:

Step-by-step explanation:

Given:

Option a:

Down payment, Da = $200

Monthly fee, Ma = $50

Option B:

Down payment, Db = $500

Monthly fee, Mb = $25

Monthly fee, M = payment, P/number of months, n

Total cost, Pc = down payment, D + payment, P

Equating both options we have:

500 + 25 × n = 200 + 50 × n

500 + 25n = 200 + 50 n

25n = 300

n = 300/25

= 12 months

At 12 months, both payment options will be the same.

Answer:

<em>The perimeter of the bedroom floor is 44 ft</em>

Step-by-step explanation:

<u>The Perimeter of a Rectangle</u>

Given a rectangle of width W and length L, the perimeter is the sum of all four sides:

P = 2W + 2L

We know a rug of dimensions 6 ft x 10 ft is located at the center of a bedroom floor and there are 1.5 ft exposed on all four sides of the bedroom.

Adding this length to each side, we have the dimensions of the bedroom as:

6 + 1.5 + 1.5 = 9 ft

10 + 1.5 + 1.5 = 13 ft

Thus, the perimeter of the bedroom floor is:

P = 2*9 + 2*13 = 44 ft

The perimeter of the bedroom floor is 44 ft

A line contains the points (-1, 6), (6, k) and (20, 3). What is the value of k?

AURORKA [14]

Consider, pls, this option:
1. if a required line has a form y=ax+b, then points A(-1;6); B(6;k) and C(20;3) belong to it.
2. According to the item 1 it is possible to make up the system of equations for A and C:
$\left \{ {{-a+b=6} \atop {20a+b=3}} \right \ \left \{ {{a=- \frac{1}{7} } \atop {b= \frac{41}{7} }} \right.$
Knowing, that a=-1/7 and b=41/7, it is possible to write the equation of required line:
$y=- \frac{1}{7}x+ \frac{41}{7}$
3. Using coordinates of point B:
$k=- \frac{6}{7}+ \frac{41}{7} =5 \ where \ k=y$

Answer: 5.
