givi [52]

Answer:

52 m

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 + 39^2 = 65^2

a^2 + 1521 = 4225

4225 - 1521 = 2704

Square root of 2704 = 52

A bag has 7 red marbles, 8 blue marbles, and 5 purple marbles. Rachel draws a marble from the bag without looking.
Fiesta28 [93]
First you would add all the marbles together because you need to know how many are in the bag in total.

7 + 8 + 5 = 20

Next you simply put the number for blue over the total

8 / 20

And there's your answer.

Help pls!!!! And I will give pizza forever!!!
SOVA2 [1]
The number of red  beads are increasing by 2  for each new pattern
The next number of reds will be 12.  ( in patern 5)

number of blue beads in pattern 5 will be 15 ( increasing by 3 )

nth term for red  = 4 + 2 (n-1)  ( its an arithmetic sequence)

nth term for blue =  3 + 3(n - 1)   - as above ,arithmetic.

Total beads in pattern 45 is

No. red beads in pattern 26   = 4  + 2(26-1)  = 4 + 50 = 54
No  blue beads in pattern 60 =  3 + 3(59)  =  180

Total number of beads in pattern 45 is:-

 4 + 2(44) + 3 + 3(44)  =   227

Tell whether the ordered pair is a solution of the given system. (-2,-4) {y=1/2x -3, y=-2x-8}
kompoz [17]

Answer:

The ordered pair (-2,\, -4) is indeed a solution to the system:

\left\lbrace\begin{aligned} & y = \frac{1}{2}\, x - 3 \\ & y = -2\, x - 8\end{aligned}\right..

Step-by-step explanation:

Consider a system of equations about variables x and y. An ordered pair (x_{0},\, y_{0}) (where x_{0} and y_{0} are constant) is a solution to that system if and only if all equations in that system hold after substituting in x = x_{0} and y = y_{0}.

For the system in this question, (-2,\, -4) would be a solution only if both equations in the system hold after replacing all x in equations of the system with (-2) and all y with (-4).

The \texttt{LHS} of the equation y = (1/2)\, x - 3 would become (-4). The \texttt{RHS} of that equation would become (1/2) \, (-2) - 3. The two sides are indeed equal.

Similarly, the \texttt{LHS} of the equation y = -2\, x - 8 would become (-4). The \texttt{RHS} of that equation would become (-2)\, (-2) - 8. The two sides are indeed equal.

Thus, x = (-2) and y = (-4) simultaneously satisfy both equations of the given system. Therefore, the ordered pair (-2,\, -4) would indeed be a solution to that system.
