A square pyramid has side lengths each measuring 8 centimeters. The height of the pyramid is 3 centimeters What is the lateral area of the pyramid?

84 square centimeters

Answers

Answer:

C. 80 square centimeters

Step-by-step explanation:

Edge 2021

The lateral surface area of the given square pyramid is 80 cm².

What is lateral surface area?

The lateral surface of an object is its entirety, excluding its base and top (when they exist).

Boundary - layer surface zone equals lateral surface area. This is to be contrasted from the total surface area, which includes the lateral surface area along with the base and top regions.

Given that, a square pyramid has side lengths each measuring 8 centimeters.

The height of the pyramid is 3 centimeters.

The lateral area of a square pyramid = 2al = 2a√[(a²/4) + h²]

= 2×8√[(8²/4) + 3²]

= 16√[(64/4) + 9]

= 16√[16 + 9]

= 16×5

= 80 cm²

Therefore, the lateral area of the pyramid is 80 cm².

Answers

Answer:

7pi/theta = radius

Step-by-step explanation:

So we are using the arc length, central angle(in radians), and radius.

We know arc length, which is 7pi.

We don't know theta, which does not matter.

And finally, we don;t know radius, which is what we are looking for.

To find radius, we use:

arc length/theta=radius

Lets plug in our values:

7pi/theta=radius.

So the answer to the khan acadamy question is

7pi/∅

Here are some othr things that may help:

Radian * Radius = arc length

This solves for arc length

Here is another one:

Arc length/radius= radian

This solves for radians

Hope these help! :)

A square mirror has an area of 25 square feet. How long is each edge of the mirror?

Answers

Each edge is 5 feet.
———-
The length is 5 and the width as well. To find the area of the square mirror, you would multiply each side to get 25 ft squared. See attached image for more details.

A running track has two semi-circular ends with radius 25m and two straights of length 87.6m as shown.
Calculate the total distance around the track rounded to 1 DP.

Answers

The total distance around the track is 332.2 meters

How to calculate the total distance?

The complete question is in the attached image

The given parameters are:

Radius, r = 25 m

Length, l = 87.6 m

Start by calculating the circumference of the two semi-circular ends using:

[tex]C = 2\pi r[/tex]

So, we have:

C = 2* 3.14 * 25

Evaluate

C = 157

The total distance around the track is then calculated as:

Total = 2l + C

This gives

Total = 2 * 87.6 + 157

Evaluate

Total = 332.2

Hence, the total distance around the track is 332.2 meters

Working alone, it takes Scott 16 minutes to inflate twenty balloons, Ashley can inflate the same twenty balloons in 15 minutes. Find how long it would take them if they worked together.

Answers

Answer:

7.74 minutes

Step-by-step explanation:

Scott's rate = 20 /16 = 1.25

Ashley's rate = 20 / 15 = 1.333

Combined rate = (1.25 + 1.3333) = 2.583333

Hence, time it will take to inflate 20 balloons :

Rate = number of balloons / time taken

2.583333 = 20 / time taken

Time taken = 20 / 2.583333

Time taken = 7.7419

It will take them approximately 7.7 minutes to inflate 20 balloons

Answer:

[tex]22\ km[/tex]

Step-by-step explanation:

One is given the following information:

[tex]10\frac{1}{1}[/tex] km were covered on Thursday[tex]10\frac{1}{1}[/tex] km were covered on Friday

One is asked to find the total distance covered on both of these days. In order to do so, one must remember in a fraction, any number over (1) is equal to the numerator (number over the fraction bar). Thus one can form the following equation:

[tex](Thursday)+(Friday) = Total\ distance[/tex]

Substitute,

[tex](Thursday)+(Friday) = Total\ distance[/tex]

[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]

Simplify,

[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]

[tex](10+1)+(10+1) = Total\ distance[/tex]

[tex](11)+(11)=Total\ distance[/tex]

[tex]11+11=Total\ distance[/tex]

[tex]22=Total\ distance[/tex]

Answers

Answer:

Implicit Form: 4x + y - 52 = 0

Step-by-step explanation:

8x + 2y = 104 => Move constant to the left and change the sign

8x + 2y - 104 = 0 => Divide both sides of the equation by 2

4x + y - 52 = 0

write an explicit formula for an, the nth term of the sequence 11,2,-7

Answers

Answer:

[tex]a_{n}[/tex] = 20 - 9n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 2 - 11 = - 7 - 2 = - 9

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 11 and d = - 9 , then

[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n

Use the Arithmetic Series formula to calculate the sum:

-6+(-3)+0+ • • • + 162

(Hint: how many numbers are being added?)

Answers

Answer:

Step-by-step explanation:

The common difference is 3.

nth term = -6+(n-1)3

-6+(n-1)3 = 162

(n-1)3 = 168

n-1 = 56

n = 57

162 is the 57th term.

S₅₇ = 57×(a_1+a_{57})/2

= 57×(-6+162)/2

= 57×156/2

= 57×78

= 57×(-6+162)/2

= 4446

A baker made 6 pounds of dough. He used 8 9 of the dough to make sandwich rolls. How much of the dough is left over?

Answers

Answer:

2/3 pound of dough is left

Step-by-step explanation:

Amount of dough available = 6 pounds

The amount used in making sandwich rolls = 8/9 of the total amount

= [tex]\frac{8}{9} \times6 = 5\frac{1}{3} pounds[/tex]

Therefore, amount of dough left over [tex]= 6- 5\frac{1}{3} = \frac{2}{3} \\[/tex]

Hence, 2/3 pounds of dough is left
