Answer:

Angle 1 = Angle 2 = 5y -23            (Vertically opposite)

We can see that we have a triangle in the figure

Since the sum of all angles of a triangle is 180,

<em>(2x + 13) + (47) + (5y -23) = 180</em>

<em>2x + 5y + 37 = 180</em>

<em>2x + 5y = 143</em>

5y = 143 -2x -----------------(1)

Assuming l and m to be parallel

<em>angle 1  = 3x (corresponding angles)</em>

<em>5y - 23 = 3x </em>

<em>From equation (1)</em>

<em>143 -2x - 23 = 3x </em>

<em>120 = 5x </em>

x = 24 ---------------------- (2)

Using (2) in (1)

<em>5y = 143 - 2(24)</em>

<em>5y = 143 - 48</em>

<em>5y = 95</em>

y = 19

Therefore,

x = 24

y = 19

Jeremy didn't pay his previous month's credit card bill in full. This month's bill shows a finance charge of $85.50. Jeremy calc
Nostrana [21]

Answer:

The monthly percentage rate would be 1.6%

Step-by-step explanation:

Given,

Finance charge = $ 85.50,

Amount of bill in this month  = $ 5,343.75,

Hence, the monthly rate of percentage

=\frac{\text{Finance charge}}{\text{Amount of bill}}\times 100

=\frac{85.5}{5343.75}\times 100

=\frac{8550}{5343.75}

=\frac{855000}{534375}

= 1.6 %

i.e. OPTION A would be correct.

You have a garden in your backyard that measures 15 meters by 20 meters. You want to place stepping stones around the perimeter
Anettt [7]

Answer:

0.5 m

Step-by-step explanation:

Given that the dimensions of the garden are 15 meters by 20 meters.

The area of the new garden (original garden + stone placed around the perimeter) is 336m².

Let d be the width of the border having stepping stones as shown in the figure. The shaded region in the figure is the area having stepping stones.

The area including the shaded region = (15+2d)(20+2d) m^2

\Rightarrow 336  = (15+2d)(20+2d) \\\\\Rightarrow 336  = 300+ 70 d +4d^2 \\\\\Rightarrow 4d^2 +70d+300-336=0 \\\\\Rightarrow 4d^2 +70d-36=0 \\\\\Rightarrow 2d^2 +35d-18=0 \\\\\Rightarrow 2d^2 +36d-d-18=0 \\\\\Rightarrow (2d-1)(d+18)=0 \\\\\Rightarrow (2d-1)=0, \; or \; (d+18) \\\\\Rightarrow d= 0.5\;or -18 \\\\

As the width of the stone border can't be a negative value, so taking the positive value.

Hence, the width of the stone border is 0.5 m.

So, the wi
