Surface Area of Prisms
Can someone show me how to solve and also what the formula is. Please!
Answer:
400 in.²
Step-by-step explanation:
Surface area of the triangular prism = bh + L(s1 + s2 + s3)
Where,
b = 8 in.
h = 15 in.
s1 = 17 in.
s2 = 15 in.
s3 = 8 in.
L = 7 in.
Plug in the values
S.A = 8*15 + 7(17 + 15 + 8)
S.A = 120 + 7(40)
S.A = 120 + 280
S.A = 400 in.²

Answer:
A = 70
Step-by-step explanation:
CB is equal to EZ and E equals 35, and E and C are the same, therefore, both E equals 35. Since there's 180 degrees in a triangle, and ABY equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that B equals 75. You have to add E and B (35 + 75), since that's in the same triangle as A. When you do that, you get 110. Subtract 180 - 110 to get A, which is 70.

If the perimeter of the parallelogram is 102 feet and the top of the parallelogram measures as 3m and the side measures as m, then what is m? (M does not stand for meters m is a variable.)
Answer:
48 meters.
Step-by-step explanation:
The perimeter of a parallelogram is given by the formula:
\(P=2(a+b)\)
Where a is the measure of the length (top), and b is the measure of the slant height (side).
We know that the perimeter is 102.
We also know that the top is 3.
So, let’s substitute 102 for P and 3 for a and solve for b, the side. So:
\(102=2(3+b)\)
Divide both sides by 2:
\(51=3+b\)
Subtract 3 from both sides:
\(b=48\text{ meters}\)
Therefore, the side measures 48 meters.

A rectangular prism made up of unit cubes. There are 4 layers, and each layer is 7 units long and 8 units wide.
The expression that can be used to represent the volume of the given rectangular prism is 4 × 7 × 8 units³.(Option 1).
What is rectangular prism?
A three-dimensional geometric object having six rectangular sides is referred to as a rectangular prism or rectangular cuboid. It is defined by its length, breadth, and height and is created by piling identical rectangular layers (or cross-sections) on top of one another (or depth). The product of a rectangular prism's length, width, and height determines its volume. Rectangular prisms are crucial to many branches of mathematics and physics, including geometry, calculus, and mechanics. They are frequently used to simulate real-world objects, such as boxes, structures, and containers.
Given that, the prism has 4 layers, each of which is 7 units long and 8 units wide.
So by the formula of rectangular prism we have to multiply the three quantities that is number of layers , length and width.
That means,
(4 units)×(7 units)×(8units)
Multiplying three of them we have the expression 4×7×8 units³
Hence, the expression that can be used to represent the volume of the given rectangular prism is 4 × 7 × 8 units³.

find the curvature of r(t) at the point (7,1,1), r(t)=<7t,t2,t3>
The equation for curvature is given by κ = |r' × r''|/|r'|3 where r' = dr/dt and r'' = d2r/dt2. the curvature of r(t) at the point (7,1,1), r(t)=<7t,t2,t3> is √14/√490.
The equation for curvature is given by κ = |r' × r''|/|r'|3 where r' = dr/dt and r'' = d2r/dt2.
We are given the point (7,1,1) which is the same as t=1.
Therefore, we can substitute t=1 into the function r(t) to obtain r(1) =<7,1,1>.
From this, we can calculate the derivatives r' and r'' of the function r(t) at the point (7,1,1).
r' = <7,2,3>
r'' = <0,2,6>
Then, we can calculate the curvature κ using the equation κ = |r' × r''|/|r'|3.
κ = |<7,2,3> × <0,2,6>|/|<7,2,3>|3

let triangle ABC be a right triangle with the right angle at C. suppose that the bisector of the interior angle at B intersects AC at D. suppose also that the bisector of the exterior angle at B intersects AC at E. if BD = 15 and BE = 20 determine the perimeter of triangle ABC
The perimeter of triangle ABC is 240 units. Using the given information, we determined the lengths of the remaining sides using the angle bisector theorem and the Pythagorean theorem. The lengths of AB, BC, and AC are 45, 75, and 120 units, respectively.
To find the perimeter of triangle ABC, we need to determine the lengths of the remaining sides.
Given that BD = 15 and BE = 20, we can use the properties of the angle bisectors to find the lengths of the other sides.
Let's denote the length of AB as a, BC as b, and AC as c.
Using the Angle Bisector Theorem, we know that the ratios of the lengths of the sides are equal. Therefore, we have
BD/DC = AB/AC => 15/(AC-15) = a/c ----(1)
BE/EC = AB/AC => 20/(AC+20) = a/c ----(2)
Setting the right sides of equations (1) and (2) equal to each other, we can solve for AC:
15/(AC-15) = 20/(AC+20)
Cross-multiplying and simplifying, we get
15(AC+20) = 20(AC-15)
15AC + 300 = 20AC - 300
5AC = 600
AC = 120
Now that we have the length of AC, we can find the lengths of AB and BC using the Pythagorean theorem:
AB² + BC² = AC²
a² + b² = c²
a² + b² = 120²
We also know that the sum of the lengths of the two legs (AB and BC) will be equal to the hypotenuse (AC):
a + b = 120
We have two equations with two unknowns, so we can solve this system of equations to find the values of a and b.
By solving these equations, we find that a = 45 and b = 75.
Finally, the perimeter of triangle ABC is
Perimeter = AB + BC + AC = a + b + c = 45 + 75 + 120 = 240 units.

Which number is equal to four and one-sixth?
four and sixteen hundredths with the six repeating
six twenty-fifths
4.2
416%
Answer:
4.2
Step-by-step explanation:
Four and one-sixth is equal to 4.2. One-sixth is the same as 1/6, which is equal to 0.16666666666666666. When you add this fraction to 4, you get 4.166666666666667, which can be rounded to 4.2. Four and sixteen hundredths is equal to 4.16, which is close to 4.2 but not exactly the same. Six twenty-fifths is equal to 0.24, which is also not equal to 4.2. 416% is equal to 4.16, which is also not equal to 4.2.
In a survey of 750 Florida teenagers, 84% said that helping others who are in need will be very important to them as adults. The margin of error is ±3. 1%. Give an interval that is likely to contain the exact percentage of all Florida teenagers who think that helping others who are in need will be very important to them as adults. The interval is from
% to %
To say with 95% confidence that the percentage of all Florida teenagers think that helping others are in need will be very important to them as adults is likely to be between 80.9% and 87.1%.
The margin of error to find the interval:
margin of error = z × √(p × (1 - p) / n)
z is the z-score corresponding to the desired level of confidence (let's use 95% confidence gives a z-score of 1.96), p is the sample proportion (0.84), n is the sample size (750).
Plugging in the values, we get:
3.1 / 100 = 1.96 × √(0.84 × 0.16 / 750)
Solving for p, we get:
p = 0.84 ± 0.031
So, the interval that is likely to contain the exact percentage of all Florida teenagers think that helping others are in need will be very important to them as adults is:
(0.84 - 0.031) to (0.84 + 0.031)
