how do you find the surface area for a triangular prism step by step please.

Answers

Answer:

Find the area of the two triangular bases:

Measure the base and height of one of the triangular bases.

Multiply the base by the height, and then divide the result by 2 to get the area.

Repeat this process for the other triangular base.

Find the perimeter of the triangular base:

Measure the three sides of the triangular base.

Add the three sides together to get the perimeter.

Find the lateral area of the prism:

Multiply the perimeter of the triangular base by the height of the prism.

Add the area of the two triangular bases and the lateral area of the prism to get the total surface area.

Here is an example problem to help illustrate these steps:

Example:

Find the surface area of a triangular prism with a triangular base that has a base of 4 cm, a height of 6 cm, and a height of 10 cm.

Solution:

Step 1: Find the area of the two triangular bases.

Area of one triangular base = (4 cm x 6 cm) / 2 = 12 cm^2

Area of the other triangular base = (4 cm x 6 cm) / 2 = 12 cm^2

Step 2: Find the perimeter of the triangular base.

Perimeter of the triangular base = 4 cm + 5 cm + 6 cm = 15 cm

Step 3: Find the lateral area of the prism.

Lateral area of the prism = Perimeter of the base x Height of the prism

Lateral area of the prism = 15 cm x 10 cm = 150 cm^2

Step 4: Add the area of the two triangular bases and the lateral area of the prism.

Total surface area = 2 x 12 cm^2 + 150 cm^2

Total surface area = 174 cm^2

Therefore, the surface area of the triangular prism is 174 cm^2.

Answer:

Volume of Triangular Prism = ½ × b × h × lWhere b is the base length, h is the height of the triangle and l is the length between the triangular bases.

In a chemistry lab, there are 9.52 grams of a powdered substance in a container. Max needs to place an equal amount of the powdered substance into each of 3 glass plates. The amount of powdered substance he places into each glass plate is 1.98 grams.

Max estimates that there are about 4.5 grams of the powdered substance remaining in the container. Is his statement reasonable?
A.
This is not reasonable because 9.52 grams can be rounded to 9.5 grams and 1.98 grams can be rounded to 2 grams. Since 9.5 − 3(2) = 3.5, there would be about 3.5 grams of the powdered substance remaining in the container.
B.
This is reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 2.5 grams. Since 9 − 3(2.5) = 1.5, there would be about 1.5 grams of the powdered substance remaining in the container.
C.
This is reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 1.5 grams. Since 9 − 3(1.5) = 4.5, there would be about 4.5 grams of the powdered substance remaining in the container.
D.
This is not reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 1 gram. Since 9 − 3(1) = 6, there would be about 6 grams of the powdered substance remaining in the container.

3743x902=?
BEST ANSWER AND EXPLANATION GETS BRAINLIEST

Answers

Answer:

The result of multiplying 3743 and 902 is 3,377,426.

Step-by-step explanation:

Certainly!

To multiply two numbers, you need to follow these steps:

Write down the two numbers one above the other, with the rightmost digit of the second number under the rightmost digit of the first number.

3 7 4 3

× 9 0 2

--------

Multiply the rightmost digit of the second number by each digit of the first number, starting from the rightmost digit, and write down the results under each digit of the second number.

3 7 4 3

× 9 0 2

--------

In this case, 2 (the rightmost digit of the second number) is multiplied by each digit of the first number (starting from the rightmost digit), resulting in 6 (2 x 3), 18 (2 x 4), 27 (2 x 7).

Add up the results from step 2 and write down the total under the line.

3 7 4 3

× 9 0 2

--------

3 3 7 7

4. Move the second number one place to the left and repeat steps 2-3, but this time write the results one place to the left of the previous results.

3 7 4 3

× 9 0 2

--------

3 3 7 7

2 9 9 1

In this case, we multiply the second digit of the second number (0) by each digit of the first number, and write the results one place to the left of the previous results.

Repeat step 4 until you have multiplied each digit of the second number by each digit of the first number.

3 7 4 3

× 9 0 2

--------

3 3 7 7

2 9 9 1

--------

3 3 7 7 4 2 6

In this case, we only needed to repeat step 4 once, as the second number had only three digits.

Therefore, the result of multiplying 3743 and 902 is 3,377,426.

Answer: 3,376,186
Explanation:

Lauren has a bag that contains strawberry chews, lemon chews, and peach chews. She performs an experiment. Lauren randomly removes a chew from the bag, records the result, and returns the chew to the bag. Lauren performs the experiment 45 times. The results are shown below: A strawberry chew was selected 13 times. A lemon chew was selected 11 times. A peach chew was selected 21 times. Based on these results, express the probability that the next chew Lauren removes from the bag will be a flavor other than peach as a fraction in simplest form.

Answers

The total number of chews Lauren removed from the bag is 45, and the number of times she selected a peach chew is 21. Therefore, the number of times Lauren removed a flavor other than peach from the bag is 45 - 21 = 24.

The probability that the next chew Lauren removes from the bag will be a flavor other than peach can be expressed as the ratio of the number of times Lauren removed a flavor other than peach to the total number of times she removed a chew from the bag. Thus, the probability is:

24/45

To simplify this fraction, we can divide both the numerator and the denominator by 3:

24/45 = (83)/(153) = 8/15

Therefore, the probability that the next chew Lauren removes from the bag will be a flavor other than peach is 8/15.

Answer:

24/45 or 8/15

Step-by-step explanation:

The probability that the next chew Lauren removes from the bag will be a flavor other than peach is 24/45. This is because there are 24 chews that are not peach (13 strawberry chews + 11 lemon chews) and 45 total chews. Therefore, the probability is 24/45 or 8/15 in simplest form.

3.) If the coordinates of A and B are -5 and 7 respectively and C is the midpoint of line AB, find the CA. What is the coordinate of C?

4.) In ∠ABC, ray BD is the angle bisector of ∠ABC. If the m∠ABD = 2x + 5 and m∠DBC = 5x - 10, find:
a. value of x
b. m∠ABD
c. m∠ABC

Answers

The point between the other two is point A

2. The point between the other two is point A3. The coordinate of C is 14. x = 5, ABD = 15 and ABC = 30

The point between the other two.

Arranging the given points in order, we get:

C (-7) < A (-4) < B (2)

We can conclude that, the point A is between points C and B.

The point between the other two.

Since A, B, and C are collinear, we have:

BA + AC = BC

Substituting the given values, we get:

5 + 4 = 9

9 = 9 --- true

We can conclude that, the point A is between points C and B.

Midpoint of AB

Given that

A = -5

B = 7

We have

Midpoint C = (7 - 5)/2

Midpoint C = 1

The value of x and the angles

Here, we have

Bisector BD

This means that

2x + 5 = 5x - 10

Evaluate

3x = 15

x = 5

So, we have

ABD = 2(5) + 5

ABD = 15

Then, we have

ABC = 2 * 15

ABC = 30

This means that the measure of angle ABC is 30 degrees

Caleb bought a jacket for $52 and 3 shirts for $12 each. The sales tax is 4.5%. How much did Caleb spend for all of the items, including tax?

Round to the nearest cent (hundredth). Include the $ symbol

Answers

Answer:

Caleb spent $91.96 for all of the items, including tax.

Step-by-step explanation:

First, let's calculate the cost of the shirts:

3 shirts * $12 per shirt = $36

Now, let's add the cost of the jacket and the shirts together:

$52 + $36 = $88

Next, let's calculate the amount of sales tax Caleb has to pay:

$88 * 4.5% = $3.96

Finally, let's add the sales tax to the total cost:

$88 + $3.96 = $91.96

Therefore, Caleb spent $91.96 for all of the items, including tax.

Answers

The area of the circle that has a radius of 4 feet will be 50.2 square feet.

What is the area of the circle?

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The radius of the circle is 4 feet. Then the area of the circle is calculated as,

A = π x (4)²

Simplify the equation, then the area of the circle is calculated as,

A = π x (4)²

A = 3.14 x 16
