Answer:

1. 16 in

2. 30.72 m

Step-by-step explanation:

scale factor 1:12 where 1 is the model and 12 is the actual.

This means the actual length is 12 times larger than the model.

1. Take the actual length (16 ft) and divide by 12.

16 ft/12= 4/3 ft(1.333...)

The answer need to be in inches so you will multiply 4/3 ft* 12 to find the length in inches.

4/3*12/1= 48/3= 16 in

2. Take the model length (256 cm) and multiply by 12.

256* 12= 3072 cm

The answer needs to be in meters so you will divide 3072 cm by 100 to find the length in meters.

3072/ 100= 30.72 m

What is the volume enclosed by the slanted prism in the diagram? A. 225 cm3 B. 270 cm3 C. 300 cm3 D. 540 cm3

Leokris [45]

Answer:

Step-by-step explanation:

The volume of a slanted prism is defined as the product between the area of its base and its height.

Remember that height is the distance from the top to the bottom, reaching that bottom with a perpendicular angle.

So, in this case, the height is 9 cm, and the area of the base is 25 square centimeter.

This means the volume is

$V=Bh=25cm^{2}(9cm)=225cm^{3}$

Therefore, the right answer is A.

How do you solve 3x-100=1x+50

frutty [35]

Answer:75

Step-by-step explanation:First isolate x by getting rid of the 100 so the equation becomes 3x=x +150 then you subtract x From both sides so it’s 2x=150 then divide by two on both sides so you get X = 75

Solve each equation. Leave the answer as an improper fraction. 16x2 = 49

pashok25 [27]

32x = 49
x = 49/32
Now since u said improper lets make 49/32 to mixed first, then improper
Lets divide 32 and 49 and we get 1 with a remainder of 17
1 17/32
Now that's the mixed fraction, so now lets lastly make it improper
1 * 32 + 17
--------------
32

The answer is 49/32

A criminal has escaped in a train wreck. The police believe he could have traveled no more than 7 mi in any direction from the w

adelina 88 [10]

Answer:

A = 153.94 sq mi

Step-by-step explanation:

In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following

A = $\pi r^{2}$

A = $\pi 7^{2}$

A = $\pi 49$

A = 153.94 sq mi

A total of 153.94 square miles must be searched.
