Answer:
Step-by-step explanation:
we are given that these two fractions are equal. however, 20/r is just given in numerators and denominators that are four times as large, even though it is still equal to 5/7. we can tell this because 20 is 4 times larger than 5, which means that R must be 4 times larger than 7, right? YES. so we take 7*4 to get 28.
Answer:
x = 6
y = 45 degrees
Step-by-step explanation:
Here, we want to get the measure of x and y
For a 45-45-90 triangle, the measure of each of the internal angle asides the right angle is 45 degrees
This mean y is 45
To get x, we know we have an isosceles triangle
So the length of the third ungiven leg is x too
Mathematically, the square of the hypotenuse (side facing the right angle) is equal the sum of the squares of the two other sides
(6 √2)^2 = x^2 + x^2
72 = 2x^2
x^2 = 72/2
x^2 = 36
x = √36
x = 6
Answer:
1). 18
Step-by-step explanation:
1). The numbers above are real numbers but on a care ful look the number below it is a squrea of the number above but it's position ois swapped.
What am I saying., Let's take for example the number 4.
4² = 16 but what's written is 61
Let's take 5
5² = 25 but what's written is 52
Let's take 6
6² = 36bl but what's written is 63.
So as for 9
9²= 81 but what will be in the box = 18
2).this number two is something special
Answer:
0 & 1.
Step-by-step explanation:
√2 = 1.41421356237
F is increasing, there are no jumps: if there's a jump from an a to a b
then one of the endpoints would be a limit point of F(S)
