Answer:
959420
Step-by-step explanation:
Calculate 10 to the power of 5 and get 100000.
9.62 × 100000 − 2.58 ×
Multiply 9.62 and 100000 to get 962000.
962000 − 2.58 ×
Calculate 10 to the power of 3 and get 1000.
962000 − 2.58 × 1000
Multiply 2.58 and 1000 to get 2580.
962000 − 2580
Subtract 2580 from 962000 to get 959420.
= 959420

Answer:
The height of the larger traffic signs is 51.96 inches
Step-by-step explanation:
Given that initially, A company makes traffic signs of an equilateral triangle with the perimeter of 144 inches
Now, A company makes similar traffic signs of perimeter 1.25 of original
New perimeter will be 1.25x144=180 inches
Let triangle ABC be a larger triangle with 180inches of the perimeter.
It is given that the triangle is an equilateral triangle,
Therefore, Side AB=BC=AC
The perimeter of a triangle ABC is
AB+BC+AC=180
3AB=180
AB=60 inches
Figure show that triangle ABC and AD is the height of the triangle.
Since, the triangle ABC is an equilateral triangle,
AD is the perpendicular bisector of BC
so that,
BD=DC and Angle ADB=90
In right triangle ADB,
Angle D =90 and Angle B =60
Side BD=60/2=30 inches and AB=60 inches
Using Pythagoras theorem,
AD=51.96 inches
Thus, The height of the larger traffic signs is 51.96 inches
