Answer:

2 1/2

Step-by-step explanation:

2/3 + 1/3 =1

3 1/2-1=2 1/2

2/3 + 1/3 = 3/3
3/3 = 1
3 1/2 - 1 = 2 1/2

Answer:

S(t) = 600*0.9^t

Step-by-step explanation:

At the beginning (t = 0) the sample has 600 grams. After 1 millennium from today (t = 1) the mass will be: 600 - 600*0.1 = 600*0.9. After 2 millennium from today (t = 2) the mass will be the 90% of the mass in the previous millenium, that is: 600*0.9*0.9 = 600*0.9^2. Analogously, at time = 3, sample's mass will be: 600*0.9^2*0.9 = 600*0.9^3. In a table format, that is

t m

0 600

1 600 - 600*0.1 = 600*0.9

2 600*0.9*0.9 = 600*0.9^2

3 600*0.9^2*0.9 = 600*0.9^3

Therefore, sample's mass in grams, S(t), where t refers to millennia from today is computed as follows: S(t) = 600*0.9^t

Answer:

(-20, 19)

Step-by-step explanation:

We need to use the Midpoint Formula, which says that given two points $(x_1,y_1)$ and $(x_2,y_2)$ , the midpoint is $(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$ .

Here, we are given one of the endpoints and the midpoint:

endpoint S = (5, -8)

midpoint M = (-7.5, 5.5)

Plug these into the formula. In $\frac{x_1+x_2}{2}$ , x1 = 5, and this whole expression is equal to -7.5:

$\frac{x_1+x_2}{2}=\frac{5+x_2}{2} =-7.5$

Solve for x2:

5 + x2 = 2 * (-7.5) = -15

x2 = -15 - 5 = -20

Now, let's find y2. y1 is just -8, and the entire expression for the y-coordinate of the midpoint is equal to 5.5. So:

$\frac{y_1+y_2}{2}=\frac{-8+y_2}{2} =5.5$

Solve for y2:

-8 + y2 = 2 * 5.5

-8 + y2 = 11

y2 = 11 + 8 = 19

The coordinates of T are thus (-20, 19).

Gala2k [10]

The sum of the squares of the lengths is 58

The square of length of the hypotenuse is 58

From the question, we have

AB² = (-2-3)² +(7-5)²= 25+4 =29

BC² = (3-1)²+(5-0)²=4+25=29

AC² = (-2-1)²+(7-0)² = 9+49 = 58

Here we can see that,

AB²+BC² = AC²

The sum of the squares of the lengths of two sides (the legs) equals the square length of the third side (hypotenuse).

the sum of the squares of the lengths = AB²+BC² =29+29 = 58

the square of length of the hypotenuse= 58

Pythagoras Theorem:

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

The answer would be 54 since there is only 180 degrees in a triangle so you subtract 90 and 36 from 180. You get 54
