Answer: Im 75% sure the answer is A. Its either A or B.
Step-by-step explanation:
= 5x - 9, find each value
Answer:
BD = 88
BC = 27
CD = 61
Explanation:
Given that,
BD = 7x - 10
BC= 4x - 29
CD = 5x - 9
Here we assume BD is a line segment and C is a point lies between B & D.
BD = BC + CD
7x - 10 = 4x - 29 + 5x - 9
Now combine like terms
7x - 10 = 4x + 5x - 29 - 9
7x - 10 = 9x - 38
Move 7x from left hand side to right hand side
-10 = 9x - 7x - 38
-10 = 2x - 38
Add 38 both the side
-10 + 38 = 2x - 38 + 38
28 = 2x
Divide by 2 both the side
x = 14
Now put the value of x and find the length of BD, CD, BC
BD = 7x - 10 = 7*14 - 10 = 98 - 10 = 88
BC= 4x - 29 = 4*14 - 29 = 56 - 29 = 27
CD = 5x - 9 = 5*14 - 9 = 61
That's the final answer.
I hope it will help you.

Answer:
340 square feet
Step-by-step explanation:
If we "unwrap" the painted surface from the shed, it will have the shape shown in the attachment. It is essentially a 40' by 8' rectangle with two 10' wide by 2' high triangles added.
The rectangle area is ...
A = LW = (40 ft)(8 ft) = 320 ft²
The total area of the two triangles is ...
A = 2(1/2)bh = (10 ft)(2 ft) = 20 ft²
Then the painted area is ...
total area = 320 ft² +20 ft²
total area = 340 ft²
y''-x^2y=o
We're looking for a solution
which has second derivative
Substituting these into the ODE gives
Right away we see , and the coefficients are given according to the recurrence
There's a dependency between terms in the sequence that are 4 indices apart, so we consider 4 different cases.
and so on, with the general pattern
and so on, with
Then the solution to this ODE is
41/10
b) Find the leftover pizza if any.
Answer:
a) 4 1/10 slices eaten
b) cannot be solved because we don't know how many slices in each pizza
Step-by-step explanation:
5*1/10=5/10
12*3/10=36/10
36/10+5/10=41/10
41/10=4 1/10 slices
We have been given a rectangular prism and we are required to find its surface area and volume.
We shall solve this question by first stating the formula of the parameter we want to find, then, we apply the respective formulas to find the values of these parameters.
Surface area:
The surface area is the sum total of all the areas of all the faces of the prism.
To solve this question, we need to note that there are 6 faces whose area we must calculate but out of the 6, there are two faces
each that are equal in area.
From the above figure, we have that:
FACE 1 = FACE 2
FACE 3 = FACE 4
FACE 5 = FACE 6.
Thus, once we find the area of FACE 1, we already have the area of FACE 2 and so on.
Also, since each face is a rectangle, the area of a rectangle is given by:
Now, let us calculate the area of FACE 1, 3 and 5.
Now we just sum up all the areas and multiply them by two to account for FACES 2, 4 and 6
Therefore, the Surface area of the rectangular prism is:
452 square inches
Volume:
The formula for the volume of a rectangular prism is given as:
The length, width, and height are shown in the figure below:
Thus, we can easily calculate our volume as shown below:
Therefore, the Volume of the rectangular prism is:
V = 504 cubic inches
To recap, the final answers are:
Surface Area = 452 square inches
Volume = 504 cubic inches
