Find the volume in cubic feet of the right rectangular prism pictured below

Mathematics
1 answer:
IgorLugansk [536]3 years ago
3 0
We know that
2 3/8------> (8*2+3)/8-----> 19/8 ft
3 1/2-------> (3*2+1)/2-----> 7/2 ft
[volume of the rectangular prism]=(19/8)*(7/2)*(8)-------> 1064/16----> 133/2 ft³
133/2 ft³ -----> 66.5 ft³------> 66 1/2 ft³

the answer is 66 1/2 ft³

wlad13 [49]

Answer:

The tree that Laura had to cut had 306 apples.

Step-by-step explanation:

Given that Laura has 78 apple trees in her cider farm, with a mean of 460 apples per tree, but then she has had to get a tree cut down, and after that, the mean of apples per tree became 462, to determine how many apples were there on the tree that Laura had to cut down, the following calculation must be performed:

(78 x 460) - (77 x 462) = X

35.880 - 35.574 = X

306 = X

Thus, the tree that Laura had to cut had 306 apples.

Marcy is making a hooked circle-shaped rug for her mother. The circumference of the circle-shaped rug is 56.52 inches.
NNADVOKAT [17]
So we want to find the radius of the circle. So just divide 56.52 by 3.14 and 2, which is 9. And then to find the area, just square 9 and multiply it by pi, which is 354.34 square inches.

The area of the rug is 354.34 square inches.

What is the area of trapezoid ABCD? A(-2,2) B(2,5) C(11,-7) D(1,-2)
Ksenya-84 [330]

Answer:

50 sq. units

Step-by-step explanation:

Join one diagonal of the trapezoid ABCD.

Assume that AC is the diagonal.

So, Area of the trapezoid = Area of Δ ABC + Area of Δ CAD.  

Now, coordinates of A(-2,2), B(2,5), C(11,-7) and D(1,-2) are given.

We know, that three vertices of a triangle are (x_{1},y_{1} ), (x_{2},y_{2}  ) and (x_{3},y_{3}  ) respectively, then the area of the triangle will be given by  

\frac{1}{2} |x_{1}(y_{2}-y_{3})+x_{2}(y_{3}-y_{1})+ x_{3}(y_{1}-y_{2} ) |

Hence, area of Δ ABC will be  

\frac{1}{2} |-2(5-(-7))+2(-7-2)+11(2-5)|= 37.5 sq units.

Again, area of Δ CAD will be  

\frac{1}{2} |11(2-(-2))-2(-2-(-7))+1(-7-2)|= 12.5 sq units.

Therefore, the area of the trapezoid ABCD will be (37.5 + 12.5) = 50 sq, units. (Answer)
