Mathematics
1 answer:
leva [86]2 years ago
4 0
<span>Since the paddock assumes a rectangular shape the area is 1/2 * b * h. From Pythagorean AB^2 = BC^2 + AC^2 (3)^2 = (x + 0.4)^2 + x^2 9 = x^2 + 0.8x + 0.16 + x^2 So 2x^2 + 0.8x + 0.16 - 9 = 0 2x^2 +0.8x- 8.84 = 0 Using the quadratic formula The solutions are 1.911 and -2.31 The area therefore is area=1/2 * b * h =1.91*2.31/2 = 2.21km² 1hectare = 0.01km² 2.21km^2 = 221ha</span>

(-1,5) (0,2) in slope intercept form
xeze [42]

Answer:

Step-by-step explanation:

(-1,5) (0,2)

y2= 2, y1 = 5, x2 = 0, x1 = -1

Slope m = [y2 - y1]/[x2 - x1]

m = {2 - 5}/{0+1}

m = -3/1

m = -3

And

y - y1 = m(x - x1)

y - 5 = -3(x + 1)

y - 5 = -3x - 3

y = -3x - 3 + 5

y = -3x + 2

A used car lot sold 15 SUVs last month, along with 80 other vehicles. Considering this
sergiy2304 [10]

Answer:

12

Step-by-step explanation:

First, find the total number of vehicles sold.

15 SUVs were sold, and 80 others were sold

15+80

95

So, 95 vehicles were sold in total.

Now we can make a proportion

15 out of 95 vehicles were SUVs, and we can expect x out of 76 vehicles to be SUVs

15/95=x/76

Cross multiply

95*x=15*76

95x=1140

To solve for x, we need to get x by itself. Since x is being multiplied by 95, divide both sides by 95. This will cancel out the 95, and leave x isolated.

95x/95=1140/95

x=12

So, 12 out 76 vehicles should be SUVs
