Answer:
Number of cm= 40 cm
Step-by-step explanation:
Giving the following information:
3 cm equals 45 kilometers
1 cm= 45 /3 = 15km
<u>We need to determine how many centimeters represents 600 km. We will use the following formula:</u>
<u></u>
Number of cm= total km / km per one cm
Number of cm= 600 / 15
Number of cm= 40 cm
Answer:
The overall average is 70 dollars for all weeks together
Answer: The area of the enlargement is 315cm.
Step-by-step explanation:
If the picture has 35cm as the area and it has a length of 7cm then we can find the width by dividing the area by the length.
w= 35/7
w = 5
So in this care the width of the picture in 5cm.
Now is saying that the picture's length has been enlarge or been dilated to 21 cm. To get from 7cm to 21cm you will have to multiply by 3.
In this situation, we will have to multiply the original picture's width by 3 to find it enlargement.
w= 5*3 = 15
The width is 15cm and the length is 21cm so multiply them to find the area.
A = 15 * 21
A = 315cm
Answer:
3 units^2
Step-by-step explanation:
Note that two vertices of this triangle are on the same line, the y-axis, since the x-coordinates are the same (0). The distance between them is (2 - 0), or 2. This represents the height of the triangle, since we're measuring straight up from the x-axis to the vertex (0, 2).
The one remaining vertex, (3, 0) lies on the x-axis. The distance from the origin to this vertex is 3, which represents the length of the base of the triangle (3).
Thus, the area of the triangle is A = (1/2)(base)(height), or
A = (1/2)(3)(2) = 3 units^2
