Determine the lateral and total surface area of the pyramid.

Mathematics
1 answer:
Umnica [9.8K]3 years ago

Answer:                      

Lateral surface area = 45.5

Total surface area = 60.2

Step-by-step explanation: To find the lateral surface area, we first need to find the surface area of one triangle. For the triangle on the right/left, you multiply 3.5*5.8, which equals 20.3. Since this is a triangle, we multiply the product (20.3) by 1/2. The answer is 10.15. Since there are two triangles with the same dimensions as this, we multiply 10.15 by 2, which equals 20.3. For the triangle on the top/bottom, we multiply 4.2*6, which equals 25.2. Since this is a triangle again, we multiply 25.2 by 1/2. The answer is 12.6. Since there are two triangles with the same dimensions as this, we multiply 12.6 by 2, which equals 25.2. Now we add 20.3 + 25.2, which equals 45.5. This is the lateral surface area.

To find the total surface area, we now need to find the area of the base as well. To do so, we multiply 4.2 by 3.5, which equals 14.7. Now we add 45.5, the area of all the triangles, with 14.7, the area of the base. The answer is 60.2.

I hope this helps!

Based on a 4-week work month and a 40-hour
Leni [432]

Answer:

$27.69

Step-by-step explanation:

Given

Monthly budget (See attachment)

Month = 4\ weeks

Week = 40 \ hour

Required

Determine the closest hourly wage

From the attachment, the monthly budget is:

Budget = \$ 4430

First, we calculate the closest weekly earnings.

Since a month = 4 weeks.

Then

Weekly\ Earnings = \frac{\$4430}{4}

Weekly\ Earnings = \$1107.5

Next, we calculate the hourly earnings:

Since 1 week = 40 hour

Then

Hourly\ Earnings = \frac{\$1107.5}{40}

Hourly\ Earnings = \$27.6875

<em>From the list of options, the closest is: $27.69</em>

If the area of a park is exactly halfway between 2.4 and 2.5 acres what is the area of the park
Paul [167]
Get the distance between two acres.

2.5 - 2.4 = 0.1

Divide the diffence by 2
0.1 / 2 = 0.05 - Halfway between them.

Therefore, 0.05 must be taken from 2.5 acres. it must be added to 2.4 acres to get the exact area of the park.

2.5 - 0.05 = 2.45
2.4 + 0.04 = 2.45 acres

OR

Simply get the average of the two to get the area since it is exactly halfway between the two acres of land.

2.5 + 2.4 = 2.9 / 2 = 2.45 acres

aleksandr82 [10.1K]

Answer and explanation:

1. 2 × 3/10 = 6/10 = 3/5

2. 8 × 4/8 = 32/8 = 4

3. 9 × 3/9 = 27/9 = 3

4. 12 × 2/11 = 24/11 = 2 2/11

5. 3 × 5/7 = 15/7 = 2 1/7

6. 2 × 3/5 = 6/5 = 1 1/5

7. 11 × 4/8 = 44/8 = 5 4/8 = 5 1/2

8. 10 × 1/4 = 10/4 = 2 2/4 = 2 1/2

9. 5 × 1/4 = 5/4 = 1 1/4

10. 11 × 2/7 = 22/7 = 3 1/7

Hope this helps!
