Answer:

<h3>numbers of Ostrich he keep = 725</h3>

Step-by-step explanation:

Area of field = 30 × 155 + 90 × 45
Area of field = 4650 + 4050
Area of field = 8700 m²

1 ostrich need = 12 m²

numbers of Ostrich = 8700 ÷ 12

numbers of Ostrich = 725

area of triangle = 1/2(3)(4) = 6 in^2

area of rectangle = 3 x 10 = 30 in^2

area of trapezoid = 1/2(3+5)(2) = 8 in^2

area of the figure: 6 in^2 + 30 in^2 + 8 in^2 = 44 in^2

answer

44 in^2

What is the fraction -2 over 3 multiplied by -2 equal?

defon

-2/3 times -2. You change -2 into -2/1 so you can multiply numerator to numerator and denominator to denominator. You will get 4/3 (negatives cancel out)

Helpppppppppppppppp ill mark you brainlist write in y=mx+b form

Sholpan [36]

Answer:

The equation of the line in slope-intercept form is:

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

Step-by-step explanation:

Given the points

(-8, 5)

(-1, -5)

Finding the slope

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-8,\:5\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-5\right)$

$m=\frac{-5-5}{-1-\left(-8\right)}$

$m=-\frac{10}{7}$

We know the slope-intercept form of the line equation is

$y = mx+b$

where m is the slope and b is the y-intercept

substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept

$5\:=\:\frac{-10}{7}\left(-8\right)+b$

$\frac{80}{7}+b=5$

$b=-\frac{45}{7}$

now substituting m = -10/7 and b = -45/7 in the slope-intercept form

$y = mx+b$

$y\:=\:\frac{-10}{7}x+\left(-\frac{45}{7}\right)$

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

Thus, the equation of the line in slope-intercept form is:

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

The value of y varies directly with x. When y=55, x=1/4. Determine the constant of proportionality

docker41 [41]

Answer:

k = 220

Step-by-step explanation:

Proportion of y and x

y = kx

Given :

y = 55
x = 1/4

Solving :

55 = k/4
k = 55 x 4
k = 220
