4. (01.03) matt plans to put concrete on a rectangular portion of his driveway. the portion is 8 feet long and 4 inches high. the price of concrete is $98 per cubic yard. the total cost of the concrete matt needs is $58.07. which of the following is closest to the width of the portion of the driveway on which matt plans to put concrete? [1 foot = 12 inches; 1 yard = 3 feet] (1 point)

Let's do all work in feet.
The rectangle is 8 ft long.

We convert inches to feet.
It is 4 inches high. 4 in/(12 in/ft) = 1/3 ft

The price of concrete is $98/yd^3
He spends $58.07 in concrete, so he buys $58.07/($98/yd^3) = 0.59255 yd^3

We now know the number of cubic yards he needs, so now we convert to cubic feet.
1 yd^3 = (3 ft)^3 = 27 ft^3

0.59255 yd^3 * (27 ft^3)/(1 yd^3) = 16 ft^3

He needs 16 ft^3.

The rectangular portion of the driveway is a rectangular prism. It has a volume of 16 ft^3, a length of 8 ft, and a height of 1/3 ft.

volume = length * width * height.

16 ft^3 = 8 ft * w * 1/3 ft

16 ft^3 = 8/3 ft^2 * w

w = 3/8 * 16 ft

w = 6 ft

The width is 6 ft.

The final answer is 3x3+6x2+8x+24+47x−2mark me brainliest

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
