The quotients are equal because they both go in the same number of times. The second pair of quotients just have an extra 0 at the end which just changes the place value of the number.
Answer:
B) measures of variability
Hope this helped :)
Answer:
D.) MC≅MC
Step-by-step explanation:
We already know that the hypotenuses are the same (because of that tiny line), so we need the legs (HL: hypotenuse-leg). As we can see in the picture, MC is a shared side of both triangles, and this is also the leg. Option D is correct.

Answer:
remaining cardboard area = 122.5πr²
Step-by-step explanation:
area of original rectangle = length * width
= 18r * 8r
= 144r²
- area of semi circle:
πr²
Here we have 3 semi circles with radius 3r:
- area of 3 semi circles: 3(
* π * (3r)²)
: 3(
* π * 9r²)
: 13.5πr²
- area of one semi circle with radius 4r:
(
* π * (4r)²)
(
* π * 16r²)
8πr²
- So the area of remaining cardboard:
area of rectangle - area of 4 semi circles
144r² - 13.5πr² - 8πr²
122.5πr²
we are given the following triangles:
We are asked to determine the value of "y". To do that we will use the tangent of 25:

We solve for "y" by multiplying both sides by "x":

Now, we take the tangent of 15:

Now, we solve for "y" by multiplying both sides by the denominator:

Now, we set both values of "y" equal, we get:

now, we solve for "x". First, we apply the distributive property on the right side:

Now, we substract
