8. What is the surface area of a square pyramid that has a base of 5 cm and
triangle heights of 8 cm.*

Answers

Answer 1
The answer is 40. 5 x 8, height x base = area
Answer 2

Answer:

105cm squared

Step-by-step explanation:

I put my answer here before, but somehow it got deleted, so I'm typing it again.

A square-based pyramid is made up of one square and four triangles.

We know that one side of the square is 5cm. And since all four sides of the square are the same, we know that the base is 5 x 5.

5 x 5 = 25

Therefore, the area of the base is 25cm squared.

Now, we need to find the area of one triangle. To find the area of a triangle, we multiply the base by the height, then halve it. We know that base of the triangle is 5cm as it shares a side with the square. We also know that the height of the triangle is 8cm.

5 x 8 = 40

40 / 2 = 20

Therefore, the area of one triangle is 20cm squared.

But wait! There are 4 triangles, not just one. Which means we have to multiply the area of one triangle by 4.

4 x 20 = 80

Add everything together:

25 + 80 = 105

Therefore, the total surface area of the square-based pyramid is 105cm squared.

A circular grade has a circumference of 38 yards .Lars is digging a straight line along the diameter of the garden at a rate of 3 yards.How many hours will it take to dig acceso the garden?

Answers

Answer:

It will take 4 hours to dig access to the garden.

Step-by-step explanation:

Given that a circular grade has a circumference of 38 yards, and Lars is digging a straight line along the diameter of the garden at a rate of 3 yards, to determine how many hours it will take to dig access to the garden, the following calculation, knowing that the diameter of a circle is equal to the circumference divided by π:

38 / π = X

38 / 3.14 = X

12.09 = X

12.09 / 3 = 4.03

Therefore, it will take 4 hours to dig access to the garden.

Use the information in the figure to determine the height of the pole.

Answers

(x + 5)^2 + (x/2 + 6)^2 = (30)^2

Take it from here.

Answer:

pole height = 29 ft

Step-by-step explanation:

x² = 30² - (1/2x + 6)² = 30² - (1/4x² + 6x + 36) = 900 - 1/4x² - 6x - 36

combine like terms:

x² = -1/4x² - 6x + 864

1 1/4x² + 6x - 864 = 0

divide both sides of the equation by 1 1/4:

x² + 4.8x - 691.2 = 0

(x - 24)(x + 28.8) = 0

x = 24 ft

pole height = 24 + 5 = 29 ft

Answer:

x = 286.01 inches

Step-by-step explanation:

Given that,

Height of the ramp, H = 20 inches

Angle of elevation, [tex]\theta=4^{\circ}[/tex]

We need to find the value of x. It can be solved using trigonometry as follow :

[tex]\tan\theta=\dfrac{P}{B}[/tex]

Where

P is perpendicular and B is base

So,

[tex]\tan(4)=\dfrac{20}{x}\\\\x=\dfrac{20}{\tan(4)}\\\\x=286.01\ in[/tex]

So, the value of x is equal to 286.01 inches.

Answer:

c = 85 in is the answer.

Step-by-step explanation:

a = 36 in

b = 77 in

c = ?

According to the Pythagoras theorem,

a² + b² = c²

36² + 77² = c²

1296 + 5929 = c²

7225 = c²

c = 85 in

∴ c = 85 in is the length of the missing leg.

You can use the pythagorean theorem which is a^2 + b^2=c^2
36^2+77^2=c^2
1296+5929=c^2
C^2=7225
C=-_/7225

Answer:

Q3. x = 3, y = -4

Q4. x = 2, y = -3

Q5. x = -1, y = 2

Step-by-step explanation:

Since the question is asking us to solve the system using elimination/adding, that's what I'll do.

To solve by adding, we add the like terms of both equations together.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1st question:

x + y = -1

x - y = 7

We add the first term together.

x + x = 2x

Then the second term.

y + -y = y - y = 0

Then the last term.

-1 + 7 = 6

Which becomes:

2x = 6

Then we solve the linear equation.

2x = 6

÷ 2  ÷ 2

x = 3

From the x value, we can then find y.

We can use either equation. In this example, I'll choose the first one.

x + y = -1

Substitute x = 3

3 + y = -1

-3         -3

y = -4

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2nd question:

2x + 2y = -2

3x - 2y = 12

We add the first term together.

2x + 3x = 5x

Then the second term.

2y + - 2y = 2y - 2y = 0

Then the last term.

-2 + 12 = 10

Which becomes:

5x = 10

Then we solve the linear equation.

5x = 10

÷5   ÷5

x = 2

From the x value, we can then find y.

We can use either equation. In this example, I'll choose the first one.

2x + 2y = -2

Substitute x = 2

4 + 2y = -2

-4           -4

2y = -6

÷2   ÷2

y = -3

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3rd question:

6x + 5y = 4

-6x + 7y = 20

We add the first term together.

6x + -6x = 6x - 6x = 0

Then the second term.

5y + 7y = 12y

Then the last term.

4 + 20 = 24

Which becomes:

12y = 24

Then we solve the linear equation.

12y = 24

÷12   ÷12

y = 2

From the x value, we can then find y.

We can use either equation. In this example, I'll choose the first one.

6x + 5y = 4

Substitute y = 2

6x + 10 = 4

-10          -10

6x = -6

÷6   ÷6

x = -1

Answer:

X=28

Step-by-step explanation:

If x=28 then the degrees of the corners are 26, 84, and 70

Those added together equals 180 degrees, the amount of degrees a triangle is supposed to have.

Answer:

x = 28

Step-by-step explanation:

Okay, so we know that all the angles in a triangle are supposed to add up to 180°, and we already have our 26°, so we can take that off:

180 - 26 = 154

So our two angles add up to 156, so we set up our problem like this:

3x + 2x + 14 = 154

So now we combine like terms:

3x + 2x = 5x

So now our equation is:

5x + 14 = 154

So now we just have to do the inverse operations thing:

154 - 14 = 140

140 ÷ 5 = 28

So, x = 28

if this is wrong, let me know so I can fix it

hope this helps:)

1. Suppose your credit card has a balance of $4200 and an annual interest rate of 18%. You
decide to pay off the balance over two years. If there are no further purchases charged to
the card
a. How much must you pay each month?
b. How much total interest will you pay?

Answers

Use the formula and you should figure it out easy for both hope that helps

a. I will payoff about $243 and 67 cents each month.

b. I will pay a total interest of 39.24%.

How do credit card payoffs work?

They work on the principle of compound interest.

After one year, I have to pay $(4200*18)/100 =$756 extra

which means my principle amount for second year will be 4200+756=4956$

After second year, I have to pay $(4956*18)/100=$892.08 extra

Total payoff at the end of second year=$4200+$756+$892.08=$5848.08

Therefore, each month I need to pay (5848.08/24)=$243.67

To calculate the interest:

Interest= (Total amount payoff - initial balance)*100/initial balance

            =(5848.08-4200)*100/4200

            =39.24%

B) 4 parts that are one-half each
C) 2parts that are one eighth each
D) 2 parts that are one fourth each

Answers

Answer:

C) 2parts that are one eight each.

Step-by-step explanation:

The reason I chose C) as the correct answer is becasue I evaluated it with the steps below.

A) - 8 parts that are one fourth each.

  This cannot be correct because it would surpase the 2/8ths (would be over).

B) - 4 parts that are one-half each.

  This cannot be correct because it would surpass the 2/8ths (would be over).

C) - 2parts that are one eight each.

  This can be correct because 2 parts have 1/8th. 1/8 + 1/8 = 2/8.

D) - 2parts that are one fourth each.

  This cannot be correct because the denominator is not 8, it is 4 meaning it wouldn't fit into the format the question asked for (which was 2/8).

This makes the correct answer C).

  I hope this helps you understand and helps you in your question.

PASSAGE:5 Mr. Franklin is remembered as a scientist, inventor, printer, writer, and one of our countrys important early leaders. His ant experiment is just one of many interesting stories from his life.6 One day he discovered ants crawling all over his kitchen shelf. Within minutes, a little jar of molasses was alive with them. He picked up the container and took out the pests.7 But one ant stayed inside, swallowing the sweet, sticky syrup and storing it in the pouch, or crop, inside her mouth. (All worker ants are females.)8 Because Mr. Franklin wanted to know if ants could communicate with one another, he gave this ant a challenge. He tied a piece of string around the mouth of the jar and hung it on a nail in the ceiling. Then he settled down to wait and watch.9 Shortly, the insect crawled up the inside of the container, over the rim, and down the side.10 But when she reached the bottom, there was, of course, no shelf! The ant dashed here and there and round and round. She zigged and zagged and eventually found the string.11 Then a fast march up, a dash across the ceiling, and a race down the wall and over the floor led her to an opening that let her out of the kitchen. She vanished.12 About thirty minutes later, Mr. Franklin spotted an army of ants moving like running water toward the wall. They swarmed up, flowed across the ceiling, and scrambled over to the nail holding the string. They lined up and marched, one after another, down the string and into the jar.13 Before long, there were two lines of ants on the string, one line tramping down to get at the sweet food, and the other line parading upward. They were carrying home globs of molasses in their crops.QUESTION:Which statement best summarizes Benjamin Franklins discovery in the second section of the passage?A.
