Given:
Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.
The cost of silver coating is $2.50 per sq. inches.
To find:
The total cost of silver coating for the box.
Solution:
The total surface area of a cuboid is
[tex]A=2(lb+bh+hl)[/tex]
Where, l is length, b is breadth and h is height.
Putting [tex]l=9,b=2,h=1.5[/tex], we get
[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]
[tex]A=2(18+3+13.5)[/tex]
[tex]A=2(34.5)[/tex]
[tex]A=69[/tex]
So, the total surface area of the box is 69 square inches.
Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is
[tex]Cost=69\times 2.50[/tex]
[tex]Cost=172.50[/tex]
Therefore, the cost of silver coating for the box is $172.50.

Answer:
I believe it is 584 in.
Step-by-step explanation:
10 x 4 = 40, 40 x 2 = 80.
18 x 4= 72, 72 x 2 = 144.
18 x 10 = 180, 180 x 2= 360.

6 cm 8 cm what will be the perimeter and the area of the rectangular below if it is enlarged using factor of 6.5
Answer:
The dimensions of the enlarged rectangle are 6*6.5 cm by 8*6.5 cm, or 39 by 52 cm. The area of this rect. is therefore (39 cm)(52 cm) = 2028 cm^2. The perimeter of the original rectangle is P = 2(6 cm) + 2(8 cm) = 28 cm. The perimeter of the enlarged rectangle is P = 2(39) + 2(48) = 174 cm.

Find the largest perfect square that divides 350584416
The largest perfect square that divides 350584416 is 58430736
The number is given as: 350584416
Express the number as the product of its factors
350584416 = 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3 x 7 x 7 x 7 x 7 x 13 x 13
Express the numbers as exponents
350584416 = 2^5 * 3^3 * 7^4 * 13^2
Rewrite the product as:
350584416 = 2^4 *2 * 3^2 * 3 * 7^4 * 13^2
Reorder the factors
350584416 = 2^4 * 3^2 * 7^4 * 13^2 * 2 * 3
Express the product as a product of a perfect square
350584416 = (2^2 * 3 * 7^2 * 13)^2 * 2 * 3
Write out the perfect square (k)
k = (2^2 * 3 * 7^2 * 13)^2
Evaluate the product
k = (7644)^2
Evaluate the exponent
k = 58430736
Hence, the largest perfect square that divides 350584416 is 58430736

find x:
Answer:
x=38
Step-by-step explanation:
Vertically opposite angles are equal, therefore equate the 2 angles opposite each other.
2x+5=3x-33
2x-3x= -33-5
-x= -38
x=38
Answer:
Because they are vertical angles:
(2x +5) = (3x-33)
combine like terms
5= x-33
x= 38

Ms. Rogers bought 4 bags of candies to make gift boxes for her family. Each bag contained 18 candies. She put an equal number of these candies into each of 7 gift boxes. How many candies were left over?
Answer:
2 candies were left.
Step-by-step explanation:
Number of bags of candies = 4 bags
Number of candies in each bag = 18 candies
Total number of candies = [tex]4(18)=72[/tex]
Ms. Rogers put an equal number of these candies into each of 7 gift boxes.
Divide 72 by 7
72 = 7(10) + 2
Here, remainder is 2.
So,
2 candies were left.

Answer:
You can
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them.
Answer:
To tell if a table values are proportional, the x and the y value should have a common factor. When the numbers are all divided by their common factor, the points should all be equal to each other.

An angle can be named by any of ...
its vertexan angle designator in an unambiguous place (usually inside, near the vertex)three points, with the vertex listed in the middleNote that angle ABC consisting of rays BA and BC sharing end point B can also be named angle CBA.
__
1. The rays share end point J. That is the vertex of the angle. The rays are named using the end point first, so the rays in this diagram are JH and JK.
The vertex is J; the sides are JH and JK.
__
5. We note there is an angle designator inside near the vertex, point M. That designator can be used to name the angle: angle 3.
There are only two rays that meet at vertex M, so the angle can also be named by naming the vertex: angle M.
The angle can also be named by naming an point on each ray, with the vertex in the middle: angle LMN or angle NML.
The four ways to name this angle are: angle 3, angle M, angle LMN, angle NML.
__
10. All of the angles with numeric designators have V as a vertex. Those angles are angle 3, angle 1, angle 6.
In this case, we cannot use V to name an angle, because many angles have vertex V. That name would be ambiguous, not referring to a specific angle.
The other angles that have V as a vertex can be named by naming their rays. There are 4 rays that meet at vertex V. Any two will identify an angle. There are 4·3 = 12 permutations of 4 rays taken 2 at a time. For example, if we choose to use rays VJ and VK as the two rays of our angle, we can name it two ways: JVK or KVJ. (This particular angle is also angle 1.)
So, the angles that have V as a vertex are ...
angles HVJ, HVK, HVL, JVK, JVL, KVL, JVH, KVH, LVH, KVJ, LVJ, LVK
