Answer:
8.5 yards
Step-by-step explanation:
The overall triangle, as shown by the line dividing its hypotenuse in 2, can be shown as 2 right triangles whose lengths and widths are both 7.5 and 4. With this in mind we can use Pythagorean theorem or...
By plugging in 7.5 and 4 into <em>a </em>and <em>b </em>respectively, we get the equation:
Now we can square 7.5 and 4, add them together and then square root the resultant to get our final answer.
- 56.25 + 16 = x^2
- 72.25 = x^2
- √72.25 = x
- x = ±8.5
The length of a triangle cannot be negative so disregard the possible negative value for 8.5.
Answer:
The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)
Step-by-step explanation:
Here, we want to know the scale used for the drawing of the Dinosaur by sarah.
The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)
Mathematically, we know that 1 foot is 12 inches;
So the actual height of the Dinosaur is 9 * 12 = 108 inches
So practically, what she has done is to represent a height of 108 inches by 2.5 inches
So the scale factor used will be;
108/2.5 = 43.2
The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual
Ratio and proportion
height:shadow=1.5:2
for the building, shadow=24
1.5:2=h:24
1.5/2=h/24
multiply both sides by 24
36/2=h
18=h
the building is 18 meters
The answer is the third option, -7.
Hope this helps.
Hello from MrBillDoesMath!
Answer:
Choice B: {1,2,4}
Discussion:
The range of the function is the set of "y" values shown in the table, which is 1,4,4,2. As sets do not contain duplicate elements, the range is {1,2,4). This is Choice B
Thank you,
