GIVING A BRAINLIST PLZZ ASAP

Jobisdone [24]

Answer:

(c) $3,93 more

(b) Mr. Sánchez's class earned more money.

(a) $\displaystyle [42, 37] → [j, p]$

Step-by-step explanation:

{79 = p + j

{118,17 = 1,65p + 1,36j

−25⁄34[118,17 = 1,65p + 1,36j]

{79 = p + j

{−86 121⁄136 = −1 29⁄136p - j >> New Equation

__________________________

$\displaystyle \frac{-7\frac{121}{136}}{-\frac{29}{136}} = \frac{-\frac{29}{136}p}{-\frac{29}{136}}$

$\displaystyle 37 = p$ [Plug this back into both equations above to get the j-value of 42]; $\displaystyle 42 = j$

The next step is to plug the solution into the BOTTOM EQUATION to calculate the total money earned for each class:

Sánchez's class

$\displaystyle 61,05 = [37][1,65]$

Altogether, thirty-seven fruit pies cost $61,05.

Kelly's class

$\displaystyle 57,12 = [42][1,36]$

Altogether, forty-two bottles of fruit juice cost $57,12.

* Based on the calculation, it is perfectly clear that Mr. Sánchez's class earned more money by $3,93:

$\displaystyle 3,93 = -57,12 + 61,05$

I am delighted to assist you anytime my friend!

640, 160, 40, 10, ...

WARRIOR [948]

Answer:

Option 3 and 5 are correct

Step-by-step explanation:

We have given a geometric series 640,160,40,10....

Common ratio of geometric series is $r=\frac{a_2}{a_1}$

$r=\frac{160}{640}=\frac{1}{4}$

Here our common ratio is less than zero

It will show the graph of exponential decay

Hence, option 5 is correct.

The general term of geometric series is $a_n=a\cdotr^(n-1)$

Domain will be all natural numbers since, geometric series take only natural numbers.

Here, values of "n" is domain

Hence, option 3 is correct.

Range can be any positive real numbers not only natural number

Range is the value of $a_n$

Hence, option 4 is discarded.

Graph can not be linear of a geometric series being exponential

Hence, option 2 is discarded.

Option 1 is discarded because it is exponential decay function so it can not be exponential growth.

Therefore, Option 3 and 5 are correct.

The figure below shows a rectangle ABCD having diagonals AC and DB: A rectangle ABCD is shown with diagonals AC and BD. Jimmy wr

Kisachek [45]

Answer:

Statement 3: DC=CD (Common)

Step-by-step explanation:

According from the statement given, consider ΔADC and ΔBCD, we get

AD=BC(opposite sides of a rectangle are congruent)

∠ADC=∠BCD(angles of a rectangle are 90°)

DC=CD(Common)

Thus, by SAS rule, ΔADC≅ΔBCD and by CPCTC AC=BD.

Thus, Statement 3 that is using the common sides of the triangle jimmy can prove the proof.

? ÷ 4 = 9 please help me

kkurt [141]

Answer:

Your answer would be 36

Step-by-step explanation:

You can figure this out by multiplying B by C to get A or

4 x 9 = 36

Then you can check by going

36 ÷ 4 = 9

9 = 9

This is the right answer
