We are given with height= 9 ft. Length=10 ft. Wall Brackets: 48-inch cost $12.95 68-inch cost $16.95 Distance from brackets from ends= 1 foot maximum . What is the total cost of the brackets, before tax?

Answers

Answer:

$89.7

Step-by-step explanation:

We are given with

height = 9 feet

length = 10 feet

wall brackets:

48-in costing $12.95

60-in costing $16.95

distance of brackets from ends = 1 foot

maximum distance between brackets= 24 inches

The brackets are

48/12 = 4 feet

and

60/12 = 5 feet

One of each must be used to cover the height of the shelf

The length of the shelf is

60 inch

subtracting 1 in from each side for the allowance

60 - 2 = 58 in

Dividing by 24 inches

58/24 = 2.41 ~ 3

The total cost is

($12.95 + $16.95) * 3 = $89.7

The total cost of the brackets is $89.7

What is the average per day?

Answers

To get the average in this case, divide 30 by 5:

30 hrs ÷ 5 days = 6 hrs/day

To get averages you have to divide the total number of units by the period of time/how many things there are. So in this case you divide 30 by 5 and get 6

154 sq. cm is the area of a circle
so find its radius
$\pi =(22)/(7)$

Answers

Answer:

r = 7 cm

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( where r is the radius )

Given A = 154 , then

πr² = 154 , that is

$(22)/(7)$ r² = 154 ( multiply both sides by 7 to clear the fraction )

22r² = 1078 ( divide both sides by 22 )

r² = 49 ( take square root of both sides )

r = $√(49)$ = 7 cm

Solve
3/4z-1/3=2/3z+1/5

Answers

3/4z - 1/3 = 2/3z + 1/5
3/4z - 2/3z = 1/5 + 1/3
9/12z - 8/12z = 3/15 + 5/15
1/12z = 8/15
z = 8/15 * 12
z = 96/15 = 32/5 or 6 2/5

2x = 140

x = 140/2

x = 70

Box A has a volume of 32 cubic meters. Box B is similar to box A. To create box B, box A's dimensions were tripled. What is the volume of box B? a. 864 m3
b. 288 m3
c. 96 m3
d. 32 m3

Answers

The answer would be 864 m³ if the 32 volume was tripled. This is because when we are tripling the volume of the rectangle we are increasing 3 dimension, thus we will be multiplying 3 sides by the increase of which is equal to 27. Then 32 times 32 is 864 m³

Answer:

The correct option is A.

Step-by-step explanation:

It is given that the volume of box A is 32 cubic meters.

Let dimensions of the box A are l×b×h.

It is given that the dimensions of the box B were tripled than box A. So the dimensions of the box B are 3l×3b×3h.

The volume of box A is

$V=l* b* h$
