Kevin is creating a target for a game that will be played at the school's carnival and needs to put red tape in the shape of an "x" as shown below. If the area of the square board is 25 square feet, how many feet of tape will he need?
Answer:Kevin need 14.14 feet of red tape
Step-by-step explanation:
Given: (Figure Attached)
Area of Square = 25 square feet
As we know
Area of square = length x width = a x a = 25
a * a = 25
a = ±5 by taking square root both sides
It means a = 5 as the length can not be negative
Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,
By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.
=
=
x = ± 7.07 It means x = 7.07
Now the total tape required is 2 * x = 2*7.07 = 14.14
Help please?! I don't really know what the right answer is
Answer:
the answer is x=1
Step-by-step explanation:
-6x+10=4x+20

Help I don’t understand this
Step-by-step explanation:
So lets just say the recipe calls for 1 cups flour to 2 cups sugar, if you use 4 cups of flour how many cup would you need of sugar? well you would * 2 by the same amount you multiplied to get 4 cups of flour. so you would need 4 cups flour and 8 cups sugar!

A rectangular box is designed to have a square base and an open top. The volume is to be 2048in.3
What is the minimum surface area that such a box can have?
Answer:
x=y=z in 3 dimensions. So, you have x2y=4=x3⟹x=y=3√4.
Step-by-step explanation:
Answer:
hi
Step-by-step explanation:
Let x = the length of the sides of the base and h = the height:
Volume = (area of base)(height)
V = x2h
2048 = x2h
2048/x2 = h
Surface Area = area of base + 4(area of vertical side)
SA = x2 + 4xh
Eliminate the h by using 2048/x2 = h:
SA = x2 + 4x(2048/x2)
SA = x2 + 8192 x-1
Take the derivative of SA wrt x, set it to zero, solve for x. Plug that value of x into the surface area equation to find the minimum surface area.
Ellie got a new job; the pay structure is described below. How much money will Ellie make in a week where she works 25 hours and has $3500 in sales. Hourly Pay Rate $14.50. Comission 9%.
Answer:
$677.50
Step-by-step explanation:
you will need to find the amount she makes first which will be the 25 hours x the pay rate which is 14.50 that will be $362.50 then you will need to find the comission % which will be
3500=100
? = 9
cross multiply then you get $315 add the two answers together to get $677.50
2.4 x 0.4 = ?

sorrry but since you get the answer you can add the bit you need
Step-by-step explanation:
Answer:
$38.52
Step-by-step explanation:
30 times 1.07 is x (x is now the cost after 7% sales tax)
x (which is 32.1) times 1.20 is y (y is the solution after 20% tip)
which y is equal to 38.52
Hope you understand <333
