3 0

Answer:

Step-by-step explanation:

Perimeter of square park = 2000 m

4*side = 2000

   side = 2000 ÷ 4

  side = 500 m

Area of square park = side * side

                                 = 500 * 500

                                 = 250000 m²

b) a^{m}*a^{n} =a^{m+n}\\\\2^{2}*2^{5} = 2^{2+5} = 2^{7}

DE is ⊥ to AC.

GB is ⊥ CD.

we need to find the median from the given figure.

Solution:

By Definition of Median which states that;

" a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.."

I know that the balloon weighs about 210 kg. The balloon itself weighs 7/9 out of this. The rest of the weight is composed of sa
Yuliya22 [10]

Answer:

Gas Tanks weighs 20/3kg i.e. 6.67kg while Sacks weighs 40kg

Step-by-step explanation:

Total weight = 210kg

Balloon Weight = \frac{7}{9} *210\\Balloon Weight = \frac{490}{3}kg

Balloon Weight = 163.33kg

Remaining Weight = 210 - (490/3)

=\frac{630-490}{3}

=46.67kg

Let the weight of Gas tank = g

Let the weight of Sacks = s

This remaining weight comprises of weight of Sacks and Gas Tanks.

i.e.

g+s = 140/3 = 46.67

As given that,

g=\frac{1}{6}*s

So,

s(\frac{1}{6}+1) = \frac{140}{3}

s(\frac{7}{6} ) = \frac{140}{7}

s=40kg

As provided

Now to find g:

g+s = 140/3

g=\frac{140}{3}-s\\=\frac{140}{3} -40\\=\frac{20}{3}kg\\=6.67kg

Which equation represents the line that passes through points (1, –5) and (3, –17)?
adelina 88 [10]

Answer:

y = -6x + 1

Step-by-step explanation:

y = mx + b

b = slope = (-5 - (-17))/(1 - 3) = 12/(-2) = -6

y = -6x + b

-5 = -6(1) + b

b = 1

y = -6x + 1
