Talia is finding the lateral area of the pyramid. She says that the expression


explains whether Talia is correct and why?


PLEASE HELP


-Talia is correct. The three faces have the same area base, and the area of the base is 1/2(8)(6.9)


-Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4( 1/2 (8)6.9) )


-Talia is not correct. Only the base has an area of 1/2(8)(6.9), and three other faces have a different area.


-Talia is not correct. The lateral Area has three faces, so the expression should be 3( 1/2(8)6.9) )

Answers

Answer 1

Answer:

Talia is not correct. The lateral Area has three faces, so the expression should be 3( 1/2(8)6.9) )

Step-by-step explanation:

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. This means that all three of the triangles that make up the faces of the triangular prism must be equal.

Since the dimensions of the base is known as 8 inches at the base and 6.9 inches high, the area of the base will be half the base times the height which is 1/2 x (8)(6.9).

The total surface area will be 3 times this area which will be,

Total surface area = 3( 1/2(8)6.9) )

Perimeter of a square is (12x-2y). What is the algebraic expression for the length of the side of the square?

Answers

Answer:

s = 3x - (1/2)y

The perimeter of a square is 4s, where s is the side length.  Here,

12x - 2y = 4s, and so s = 3x - (1/2)y

The surface area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for π. Round your answer to the nearest hundredth.

Answers

Answer:

[tex]267.95 cm^3[/tex]

Step-by-step explanation:

We need to first find the radius of the sphere.

The surface area of a sphere is given as:

[tex]A = 4\pi r^2[/tex]

where r is the radius

Therefore:

[tex]200.96 = 4 * 3.14 * r^2\\\\=> r^2 = 200.96 / 12.56\\\\r^2 = 16\\\\r = \sqrt{16} \\\\r = 4cm[/tex]

The radius of the sphere is 4 cm.

The volume of a sphere is given as:

[tex]V = \frac{4}{3} \pi r^3[/tex]

Therefore, the volume of the sphere of radius 4 cm is;

[tex]V = \frac{4}{3} * 3.14 * 4^3\\\\V = 267.95 cm^3[/tex]

The volume of the sphere is [tex]267.95 cm^3[/tex]

Step-by-step explanation:

Confounding variables are outside influence that changes the effect of a dependent and independent variable. In this case the outside variable is the drought, which has changed the effects of the dependent and independent variables.

Sydney is going to a carnival that has games and rides. Each game costs $1.25 and each ride costs $2.25. Sydney spent $24.25 altogether at the carnival and the number of rides she went on is 3 more than the number of games she played. Determine the number of games Sydney played and the number of rides Sydney went on.

Answers

Answer:

number of games played is 5

number of rides road 8

Step-by-step explanation:

8 x 2.25=18

5 x 1.25=6..25

18 + 6.25=24.25

The number of games Sydney played is 5 and the number of rides Sydney went on is 8.

What is linear equation?

Linear equation is the type of equation with highest power 1.

Assume the number games Sydney played be x. So, the number of rides she went is x+3.

The cost of 1 game is $1.25. So, the cost of x games will be 1.25x.

The cost of 1 ride is $2.25. So, the cost of x+3 rides will be 2.25(x+3).

The total cost is $24.25. Formulate the linear equation and solve it.

1.25x+2.25(x+3)=24.25

1.25x+2.25x+6.75=24.25

3.5x=17.5

x=5

Substitute x=5 into x+3.

5+3=8

Thus, the number of games Sydney played is 5 and the number of rides Sydney went on is 8.

Answers

Answer:

If a triangular prism and a cylinder have the same height and the same volume, then the area of bases must be equal.

=> Option A is correct

Step-by-step explanation:

Because they share the same formula to calculate V = Base area x Height

V and Height are same, then Base areas are same.

Hope this helps!

:)

If a triangular prism and a cylinder have the same height and the same volume, then their bases have the same area is true statement.

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

If a triangular prism and a cylinder have the same height and the same volume, then their bases must have the same area.

This can be explained using the formula for the volume of a prism, which is equal to the area of the base times the height.

Since the height of both shapes is the same, the volume of the shapes is proportional to the area of their bases.

If the volume is the same for both shapes, then their bases must have the same area.

Therefore, their bases have the same area is the true statement among the given statements.

What is simplification?

Using math and algebraic principles, simplification entails removing pointless variables, factors, or operations from an expression. Getting an expression that is simpler to use, manipulate, or solve is the aim. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property.

Here,
To simplify the given expression, we need to use the rules of exponents:

= [(x²y³)⁻¹ / (x⁻²y²z)²]²

= [(1 / x²y³) / (x⁻⁴y⁴z²)]²

= [(1 / x²y³) * (x⁴ / y⁴z²]²

= x⁴ / y¹⁴z⁴
