The surface area of this triangular pyramid whose bases and lateral faces are congruent equilateral triangles is

Answers

Answer 1

Answer:

The answer is below

Step-by-step explanation:

A triangular pyramid is a pyramid with a triangular base. It is a polyhedron (3 dimensional shape) composed of four triangular faces, six straight edges, and four vertex corners.

The surface area of a triangular pyramid with congruent equilateral triangles = 4 * area of one triangle

Area of one triangle = (1/2) * base * height  = (1/2) * 15 in * 13 in = 97.5 in²

Surface area of pyramid = 4 * 97.5 in² = 390 in²

what is the measure of x if angle 6 equals 4x and angle 7 equals 2x + 34

112°
64°
17°
68°​

Answers

Answer:

17°

Step-by-step explanation:

6 = 4x

7 = 2x + 34

4x - 2x = 2x

Since 6 and 7 are vertically opposite angles, they have the same angle.

2x = 34

X = 34 ÷ 2 = 17

Step-by-step explanation:

< 6 and < 7 are vertically opposite angles so.

< 6 = < 7

4x = 2x + 34°

4x - 2x = 34°

2x = 34°

x = 17°

Mary has $6,000 saved for her college education. She invested that money at 2.3% interest per year. Suppose her account earned interest compounded annually. How much interest would she earn in 3 years?

Answers

Answer:

Interest= $423.59

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $6,000

Number of periods (n)= 3 years

Interest rate (i)= 2.3% = 0.023

To calculate the Future Value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 6,000*(1.023^3)

FV= $6,423.59

Now, the interest earned:

Interest= 6,423.59 - 6,000

Interest= $423.59

Students in a health class are tracking how much water they consume each day. Victoria has two reusable water bottles: a small one and a large one. Yesterday, she drank 3 small bottles and 4 large bottles, for a total of 3,312 grams. The day before, she drank 2 small bottles and 4 large bottles, for a total of 2,888 grams. How much does each bottle hold?
please help

Answers

Given :

Let, capacity of small bottle is x and large bottle is y.

To Find :

How much does each bottle hold ?

Solution :

For condition 1 :

3x + 4y = 3312   ...1)

For condition 2 :

2x + 4y = 2888  ...2)

Subtracting equation 2) from equation 1), we get :

x = 424

Putting value of x in equation 1) is :

[tex]y = \dfrac{2888 - (2\times 424)}{4}\\\\y = 510[/tex]

Therefore, capacity of small bottle is 424 gram and large bottle is 510 gram.

A circular trampoline has a radius of 8 feet. Wendy wants to buy a cover for the trampoline. What will be the area of the cover

Answers

Answer:

Option (3)

Step-by-step explanation:

Area of a circle is given by the formula,

Area = πr²

Here, r = radius of the circle

Since, radius of the circular trampoline = 8 feet

Area of the cover required for the circular trampoline = π(8)²

                                                                                         = 64π square feet

Therefore, Option (3) will be the answer.

R=8ft

Step-by-step explanation:

Calculate r using the given formula

r = , with Area = 64π

r = ← cancel π on numerator/ denominator

r = = 8

The required value of radius of circle r is 8 ft

From Figure the area of circle is = 64π, we have to find the radius of the circle.

What is area of circle?

Area of the circle is = π[tex]r^2[/tex]

since

the area of the circle is given = 64π

And,
Radius = √area/π
radius= √64π/π
Radius = √64
Radius = 8 ft

Thus The required value of radius of circle r is 8 ft.
