Dexter is making a sculpture with the dimensions shown. What - 1

Answers

Answer 1
Answer: To find the surface area of the entire sculpture, you need to add up the surface area of each part of the sculpture.  Overall, you see two triangles connected by two rectangles at the top, and the half of a cylinder at the bottom.

To find the area of one of the two triangles, you use the equation A = (1/2)bh, where b = the base of the triangle and h = the height.  So, the area of one triangle is:

A rectangle has a width of 10 centimeters. The rectangle's length is 4 times its width. What is the perimeter of the rectangle?

Answers

Answer:

100 cm.

Step-by-step explanation:

We have been given that a rectangle has a width of 10 centimeters. The rectangle's length is 4 times its width.

The length of rectangle would be 4* 10\text{ cm}=40\text{ cm}.

We know that perimeter of rectangle is 2 times the sum of length and width of rectangle.

\text{Perimeter of rectangle}=2(\text{Length+Width)}

\text{Perimeter of rectangle}=2(\text{10 cm+ 40 cm)}

\text{Perimeter of rectangle}=2(\text{50 cm)}

\text{Perimeter of rectangle}=100\text{ cm}

Therefore, the perimeter of our given rectangle would be 100 cm.
If it's width is 10cm then it's legth has to be 40cm. So 10+10+40+40=100cm Perimeter 

There are 25 students in Mrs. Venetozzi’s class at the beginning of the school year, and the average number of siblings for each student is 3. A new student with 8 siblings joins the class in November. What is the new class average for number of siblings? Round your answer to the nearest hundredth.

Answers

It is 25/3 which gives you 8.3 but let's say it is 8. So 8 students have 3 siblings and 9 have 2-0 siblings and 8 have 4-any number higher siblings. So if that kid joins there would be an avg of 3.63 siblings so 3.63 is the answer.

The Main Street Cinema holds 1,356 people. Last Saturday night, they were sold out for two showings of Super Alien 5. There was a special price of $5 for every seat for each showing. How much money did the theater take in that night? A. $10,888 B. $9,848 C. $6,780 D. $13,560

Answers

The amount the theater take in that night is (d) $13560

How to determine the amount the theater take in that night?

From the question, we have the following parameters that can be used in our computation:

People = 1356

Number of shows = 2

Price per ticket = $5

using the above as a guide, we have the following:

Total = People * Number of shows * Price per ticket

So, we have

Total = 1356 * 2 * 5

Evaluate

Total = 13560

Hence, the amount the theater take in that night is (d) $13560
