Answer:
cost = 1296 × 2 = $2592
Step-by-step explanation:
The concrete is likely a rectangular prism base on it dimension . The width, length and height is known. The volume of the prism should be calculated since the concrete prize is known base on it volume.
volume of a rectangular prism = Lwh
where
L = length
w = width
h = height
volume = Lwh
volume = 18 × 18 × 4
volume = 1296 ft³.
The cost of the concrete is $2 per cubic ft. Therefore, the volume for 1296 ft³ can be calculated below
$2 is the cost for 1 cubic fit
how much for 1296 cubic ft
cross multiply
cost = 1296 × 2 = $2592
The answer is the third option, which is: Trapezoid.
The explanation for this asnwer is shown below:
1- A rectangular pyramid is a solid whose base is a rectangle and its faces are triangles.
2- When you slice or cut a solid with a plane, you obtain a shape which is known as "Cross section".
3- In this case, if these plane is perpendicular to the base but does not pass through the top vertex of the rectangular pyramid, the intersection of the plane with the pyramid, or the resulting shape will be a trapezoid.
<span>At the animal shelter there are 56 more dogs than cats. If the total number of animals is 200 how many of each type are in the shelter?
dogs + cats = 200 eq I
</span>dogs = 56 + cats eq II
replace dogs in eq I
(56 + cats) + cats = 200 eq with one variable
56 + 2c = 200
2c = 200 - 56
2c = 144 /divided 2
<u>cats= 72</u>
dogs = 56 + cats = 56 + 72 = 128
<u>dogs = 126</u>
