Answer:

10 cm

Step-by-step explanation:

The area of a triangle

A = 1/2 bh

We know the area and the base

45 = 1/2 * 9*h

45 = 9/2h

Multiply each side by 2/9 to isolate h

45*2/9 = 2/9*9/2h

10 = h

When the graph rises one square for a run of one square, the slope is 2 km/(0.5 h) = 4 km/h. When the graph rises half that fast, the slope is 2 km/h. When the graph is horizontal, the slope is 0. The slope of the distance vs time curve is the speed.

  • S = 4 km/h, when 0 < t < 2 h
  • S = 0, when 2 h ≤ t < 2.5 h
  • S = 4 km/h, when 2.5 h ≤ t < 3 h
  • S = 0, when 3h ≤ t < 4 h
  • S = 2 km/h, when 4 h ≤ t < 5 h

Fabio and Gwen are saving money to buy a new gaming station. They need at least $510 to purchase the new gaming station. Gwen we
Phoenix [80]

<u>Answer-</u>

Set of constraints to model the problem are,

12x+9y\geq 510

y \leq 2x

y \geq 25

<u>Solution-</u>

<em>x = the number of lawns weeded by Gwen,</em>

<em>y = the number of dogs walked by Fabio.</em>

1.

As, Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog,

\text{Earnings of Gwen} = 12x

\text{Earnings of Fabio} = 9y

\text{Total earning} = 12x+9y

They need at least $510 to purchase the new gaming station, means they need $510 or more than $510.

The equation for this is,

12x+9y\geq 510

2.

The number of dog walks that Fabio has scheduled is no more than twice the number of yards Gwen has scheduled to weed, means

y must be less than or equal to 2x.

The equation for this is,

y \leq 2x

3.

Fabio will walk at least 25 dogs, means y must be greater than of equal to 25.

The equation for this is,

y \geq 25
