Answer:
Disagree
Step-by-step explanation:
The surface area of the given prism consists of the following parts;
1) The area of the top and bottom right triangles, A₁, and A₂, which are given as follows;
A₁ = A₂ = (1/2) × 5 × 12 = 30
2) The area of the left rectangle, A₃ = 5 × 8 = 40
3) The area of the rear rectangle, A₄ = 13 × 8 = 104
4) The area of the front rectangle, A₅ = 12 × 8 = 96
∴ A = A₁ + A₂ + A₃ + A₄ + A₅
A = 30 + 40 + 104 + 96 + 30 = 300
Jim B 65 + 65 + 104 + 96 + 40 = 370
The surface area of the triangular prism, A = 300 cm²
Jim-Bob's calculation contains two errors
1) 65 + 65 + 104 + 96 + 40 = 370 ≠ 270
2) The area surface area of the triangular prism = 300 cm² not 270 cm²
and therefore, disagree with his calculation.

You buy 11 bagels with a $20 bill. How much change do you receive?
Answers
Answer:
You would receive $13.75
Step-by-step explanation: What i did was divided 7.50 by 6 so it would give me the price of 1 bagel(1.25).I subtracted 11 and 6 which would give me 5 so I know how much I need to calculate with the discount. Then I multiplyed 5 times 1.25 (6.25) so I could get the price for 5 bagels. After I added 7.50 and 6.25 which would give you your answer of $13.75.

Use Euclid's division lemma to show that the square of any positive integer is either of
the form 3m or 3m + 1 for some integer m.
Answers
Answer:
let us consider a positive integer a
divided the positive integer a by 3, and let r be the remainder and B be the quotient and such that.
a=3b+r.........(1)where =0,1,2,3
case 1:consider r=0
equation (1)becomes
a=3bon squaring both the side
a²=(3b) ²a²=9b²a²=3 x 3b²a²=3mwhere m=3b²case 2: Let R=1equation (1) become a=3b+1squaring on both the side we get a²=(3b+1)²a²=(3b) ²+1+2x(3b)x1a²=9b²+6b+1a²=3(3b²+2b) +1a²=3m+1where m=3b²+2bcase3:let r=2equation (1)becomesa=3b+2squaring on both the sides we get a²(3b+2)²a²=9b²+4(12x3bx2a²9b²+(12b+3+1)a²3(3b²+4b+1)+1a²3m+1where m=3b²+4b+1

A sound wave is given by the
following equation:
y = 6 sin(324pi t)
where t = time in seconds
How many cycles will occur
between t= 3 and t = 5.5 seconds?
Answers
Answer:
405 cycles
Step-by-step explanation:
We have the equation:
y = 6*sin(324*π*t)
For the properties of the sin function, we know that the period is 2π.
So between:
Sin(x) and Sin(x + 2*pi)
we have a cycle.
between:
Sin(x) and Sin(x + 6*pi)
we have 3 cycles.
and so on.
Now we want to find how many cycles will occur between t = 3 s, and t = 5.5 seconds
Between these times, the difference in the argument of the sin function is:
324*π*5.5 - 324*π*3 = 324*π*(5.5 - 3) = 324*π*2.5
Now, the number of cycles that we will have between these times is equal to the number of times that "2*π" is in 324*π*2.5
That number is just the quotient between 324*π*2.5 and 2*π
N = (324*π*2.5)/(2*π) = (324*2.5)/(2) = 405
There are 405 cycles between 3 seconds and 5.5 seconds.

Frances and Joyce decided to take a shortcut through the woods to go to their friend's house. When they went home they decided to take the long way around the woods to avoid getting muddy shoes. If the length of the shortcut is equal to the square root of the sum of the squares of the other two sides, what total distance did they walk?
Answers
Answer:
Length of shortcut = 15 km
Step-by-step explanation:
Given that;
Length of shortcut is equal to square root of the sum of the squares of the other two sides.
So,
We can find length of shortcut.
Assume:
Length of other two side area 12 km and 13 km
So,
H = √P² + B²
Length of shortcut = √12² + 13²
Length of shortcut = √144 + 169
Length of shortcut = √225
Length of shortcut = 15 km

Find the principal that will yield a simple interest of Rs 9000 in 5 years at a rate of 6% per annum.
Answers
9514 1404 393
Answer:
₹ 30000
Step-by-step explanation:
The simple interest formula is ...
I = Prt . . . . . . principal P invested at rate r for t years
Fill in the values you know, and solve for the one you don't know.
9000 = P(0.06)(5)
9000/0.30 = P = 30000
The principal that will give ₹9000 in interest is ₹30000.
A =?
P= 9000
t = 5 yrs
r = 6% = 0.06
A = p(1+r)^t
A = 9000(1+0.06)⁵
A = 9000× 1.338
A = 12044 Rs.

Also an isosceles triangle has two sides of equal length (as shown by the two lines drawn through the sides of the triangle)
Since you are given the angle B as 46 degrees that means that angle C is also 46 degrees (since they both share the same base and since both sides of the triangle are equal).
When added together you can subtract this from 180 degrees.
So...
180-92=88
88 is your answer.
What is an equation of the line that passes through the points (-3, -5) and
(-5, -3)?
Answers
Answer: y = -x-8
Step-by-step explanation:
(-3,-5) (-5,-3)
Slope (m) = (y-y)/(x-x) = (-3- -5)/(-5- -3) = (-3+5)/(-5+3) = 2/- 2 = - 1
m = - 1
Point (-3,-5)
y-y=m(x-x)
y- -5= -1(x- -3) = y+5 = -1(x+3)
y+5 = - x -3
y+5= - x - 3 (substract 5 from both sides)
y = - x - 8
