Answer:

8 intersections

Step-by-step explanation:

Miss Stevens drove through a total of 36 intersections on her way home from work last week.

At four of every 16 intersections Miss Stevens had to stop for a red light before she could drive through .

This is calculated as:

36 intersections ÷ 16 intersections

= 2 4/16

= 2 1/4

At four of every 16 intersections Miss Stevens had to stop for a red light before she could drive through .

4 of every 16 intersections = stop for a red light

Hence:

16/4 = 4 intersections

Hence: 4 intersections = 1 stop for a read

The number of intersections that Miss Stevens had to stop for a red light is:

2 × 4 intersections = 8 intersections

the taxi charges a flat fee of $3.75, plus $1.50 per kilometer driven. What is the total cost of a 10 km trip?
Lubov Fominskaja [6]

Answer:

$18.75

Step-by-step explanation:

Let

y = Total cost

x = number of kilometers

The equation:

y = 3.75 + 1.50x

If x = 10 km

y = 3.75 + 1.50(10)

= 3.75 + 15

= 18.75

y = $18.75

y = Total cost = $18.75

<h2 /><h2 /><h2><u>☼︎</u><u>L</u><u>e</u><u>t</u><u>:</u><u>-</u></h2>

  • The cost price of cow = Rs.x

<h2><u>☼︎</u><u>Solution :-</u></h2>

\sf x + x \: of \: x\%= 144 \\ \\ \sf \implies x + \frac{x \times x}{100} = 144 \\ \\ \sf \implies {x}^{2} + 100x - 14400 = 0 \\ \\ \sf \implies x(x - 80) + 180(x - 80) = 0 \\ \\ \sf \implies x + 180 = 0 \\ \\ \sf \implies x = - 180 \\ \\ \sf \therefore \:  {\boxed{ \sf \pink{x = 80}}}

<h2><u>Hence: </u></h2>

The cost price of cow =<u>R</u><u>s</u><u>8</u><u>0</u>
