Think of this cement traffic barrier as a rectangular prism with a trapezoidal prism on top. A solid is a triangular solid on a rectangular solid. The rectangular solid has a length of 380.0 centimetres, width 66.0 centimetres and height 25.5 centimetres. The triangular solid has the upper part removed at a height of 50 centimetres from the rectangular solid to form an upper face with a width 23.0 centimetre. What is the area of the base of each prism? What is the volume of each prism? What is the total volume of the cement needed to make the traffic barrier?

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.

answer:

c) the x-coordinate of the center of the circle increases by 3
