Which is the best estimate of the area of a triangle that has the base of 23.62 cm and height of 8.33 cm?
Alexxx [7]

Best estimate of the area of a triangle = 100 \text {cm}^2.

Solution:

Given base of the triangle = 23.62 cm

Height of the triangle = 8.33 cm

Area of the triangle = \frac{1}{2} \times \text{base}\times \text {height}

                                =\frac{1}{2}\times23.62\times 8.33

                                =\frac{1}{2}\times196.7546

                                =98.3773 \ \text {cm}^2

Area of the triangle = 98.3773 \text {cm}^2

Estimation means rounded off to the closest correct answer.

98.3773 rounded off to 100.

Hence, best estimate of the area of a triangle = 100 \text {cm}^2.

Jess observed that 60% of the people at a mall on a particular day shopped for clothes. If 2500 people at the mall did not shop
elixir [45]

(3,750 people

60%=did shop

40%=did not shop =2,500

2,500/40  =  x/100

40x = 2,500x100

40x=250,000

x = 250,000/40

x=6,250

   6,250 =all people  at the mall

6,250 - 2,500 =3,750  (60%)


   OR

(2,500 x60)/40 = 3,750
