for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³

One of the two angles is shown as 40.8 and the other one is x.
To find x subtract 40.8 from 66.8
X = 66.8-40.8 = 26
X = 26 degrees.

Answers
Answer:
Step-by-step explanation:
sir in the graph every point is (X,Y) so you should choose consecutive random numbers for the X values for the first point after that put the values you choose In the equations so now you have just numbers in the equation .. add, subtract and multiply at the end you will get a value .. ok this Y for the first point .. mark this point on the graph and continued this process until it reached at least 3 points, and connected between them.
Note : do this with each equation separately and do not connecte between two points for two different equations
the equation with x will become as line
the equation with x² will become as arch
after you finsh drwaing see the points that the tow equation are touching within and write them. Usually it is two points
Step-by-step explanation:
First, set the equations as equal to eachother because both equal y:
[tex]x^2-6x-7=x+1[/tex]
Now, solve to get everything on one side of the equation so that the other side of the equation is set to 0:
[tex]x^2-7x-8=0[/tex]
Now use the sum product pattern:
[tex]x^2+x-8x-8[/tex]
(as you can see, the above equation is equivalent to the previous equation, but there are now four values instead of three)
Now take the common factor from the two pairs:
[tex]x(x+1)-8(x+1)[/tex]
Rewrite in factored form:
[tex](x-8)(x+1)[/tex]
Now to get both values of x, set each factored equation to 0 and solve for x (becuase remember, the equation still equals 0):
[tex](x-8)=0\\x=8[/tex]
[tex](x+1)=0\\x=-1[/tex]
NOW that we have both values of x, we can subsitute them into EITHER equation and solve to get the corresponding y values:
[tex]y=(8)+1\\y=9[/tex]
[tex]y=(-1)+1\\y=0[/tex]
So that's how we solve to get these coordinates: (8,9) & (-1,0).
Good luck on your final and I hope I was able to help :)

The surface area of a lantern shaped like a sphere is 452.16 square inches. What is the approximate volume of the lantern? Use 3.14 for π. Round your answer to the nearest hundredth.
A.150.72 in.3
B.452.16 in.3
C904.32 in.3
D.5,425.92 in.3
Answers
The approximate volume of the lantern is, V = 904.32 in³
How can the surface area of this sphere can be expressed ?The concept here is using the surface area formula which is
A = Area = (4 π r² )
V= Volume =( 4/3 π r³)
Then , We get;
A / V = 3 / r
Also, r = √A / 4π
Then we can substitute the values as
π = 3.14
r = √452.16 / 4×3.14
r = √36
r = 6
Hence, We get;
V = 4/3 πr³
V = 4/3 × 3.14 × 6³
V = 904.32 in³
