Guys pls help with all the steps ​

Mathematics
1 answer:
Gwar [14]2 years ago
5 0

Step-by-step explanation:

To solve both questions you will have to use the Pythagoras theorem

{c}^{2}  =  {a}^{2}  +  {b}^{2}

c being the hypotenuse

so to find AB we say

{ap}^{2}  =  {pb}^{2}  +  {ab}^{2}

To make AB the subject of the formula, we take PB over. Therefore:

{ab}^{2}  =  {ap}^{2}  -  {pb}^{2}

now we just substitute

{ab}^{2}  =  {13}^{2}  -  {5}^{2}

{ab}^{2}  = 169 - 25

{ab}^{2}  = 144

square root both sides of the equation

ab = 12

We then use the same formula to find AQ(which is a hypotenuse)

{aq}^{2}  =  {ab}^{2}  +   {bq}^{2}

{aq}^{2}  =  {12}^{2}  +  {9}^{2}

{aq}^{2}  = 144 + 81

{aq}^{2}  = 225

square root both sides

aq = 15

A group of 2 adults and 4 children spent $38 on tickets to a museum. A group of 3 adults and 3 children spent $40.50 on tickets
mrs_skeptik [129]

Answer:

adult $8.00

child $5.50

Step-by-step explanation:

Let the price of 1 adult ticket = x.

Let the price of 1 child ticket = y.

2x + 4y = 38

3x + 3y = 40.5

Multiply the first equation by 3. Multiply the second equation by -2. Then add them.

         6x + 12y = 114

(+)      -6x - 6y = -81

-----------------------------

                  6y = 33

y = 33/6

y = 5.5

2x + 4y = 38

2x + 4(5.5) = 38

2x + 22 = 38

2x = 16

x = 8

Answer:

adult $8.00

child $5.50
