vaieri [72.5K]

Answer:

The area of the larger triangle is 315 inches²

Step-by-step explanation:

1. Let's review all the information provided for answering the questions properly:

Pre-image triangle has a base of 7 inches and a height of 10 inches

Scale used : Factor of 3

2. What is the area of the larger triangle??

For calculating the area of the larger triangle, we use the scale this way:

Base = 7 inches * 3

21 inches

Height = 10 inches * 3

30 inches

Area of the larger triangle = 1/2 (Base * Height)

Area of the larger triangle = 1/2 (21 * 30)

Area of the larger triangle = 630/2 = 315 inches²

Nina [5.8K]

Answer:

No. The results of the survey cannot be generalized to the population of all customers of the shopping mall.

Step-by-step explanation:

Survey results are biased, because data is collected from customers who came trough one specific door of the mall.

Some of the customers may be using some other door where satisfaction survey is not given to these people while passing the door.

Therefore survey results does not reflect thoughts of the population of all customers.

Suppose you take the small prism and stack it on top of the larger prism. What will be the volume of the composite figure?

Degger [83]

Find the volume of the first figure, then find the volume of the second figure, then add them together.
V=lwh
V(1)=(15)(12)(6)
= 1,080in^3
V(2)=(12)(6)(6)
= 432in^3
--------------------------------------------
1,080+432= 1,512 in^3
--------------------------------------------
Your answer should be 1,512

The two circles shown above have radii of 8 in. and 4 in. What is the Circumference of the both?

Dmitry [639]

Circumference of Circle 1 is 50.24 inches and Circumference of Circle 2 is 25.12 inches

Step-by-step explanation:

Radius of circle 1 = 8 inches

Radius of circle 2 = 4 inches

We need to find circumference of both circles.

The formula used to find the value of circumference is:

$Circumference=2\pi r$

Finding Circumference of Circle 1:

Radius = 8 inches

π = 3.14

Putting values and finding circumference

$Circumference=2\pi r$

$Circumference=2*3.14*8$

$Circumference=50.24\,\,inches$

Finding Circumference of Circle 2:

Radius = 4 inches

π = 3.14

Putting values and finding circumference

$Circumference=2\pi r$

$Circumference=2*3.14*4$

$Circumference=25.12\,\,inches$

So, Circumference of Circle 1 is 50.24 inches and Circumference of Circle 2 is 25.12 inches
