Help me slove this problem thank you

emmasim [6.3K]

Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{22 \: units}}}}$ </h3>

Step-by-step explanation:

Let the points be A and B

A ( -8 , - 18 )⇒( x₁ , y₁ )

B ( 14 , -18 )⇒( x₂ , y₂)

Finding the distance between these two points

$\sf{ \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }$

Plug the values

⇒ $\sf{ \sqrt{ {(14 - ( - 8)}^{2} + {( - 18 - ( - 18))}^{2} } }$

We know that, $\sf{( - ) \times ( - ) = ( + )}$

⇒ $\sf{ \sqrt{ {(14 + 8)}^{2} + {( - 18 + 18)}^{2} } }$

Calculate

⇒ $\sf{ \sqrt{ {22}^{2} + {0}^{2} } }$

Evaluate the power

⇒ $\sf{ \sqrt{484} }$

⇒ $\sf{{22} }$ units

Hope I helped !

Best regards!!

Ryan and Sarah collect baseball cards. Ryan has 150 baseball cards and collects 10 cards per week. Sarah has 233 baseball cards

ICE Princess25 [194]

Answer:

About 17 weeks

Step-by-step explanation:

Given

Ryan:

$Initial = 150$

$Additional = 10$ (weekly)

Sarah:

$Initial = 233$

$Additional = 5$ (weekly)

Required

Determine the number of weeks they have the same cards

Represent the number of weeks with w:

For Both individuals, number of card at any given week is:

$Initial + Additional * w$

So,

For Ryan, the expression is:

$150 + 10 * w$

$150 + 10w$

For Sarah, the expression is:

$233 + 5 * w$

$233 + 5 w$

To determine the number of weeks, we have to equate both equations:

$150 + 10w= 233 + 5 w$

Collect Like Terms

$10w - 5w = 233 - 150$

$5w = 83$

Solve for w

$w = 83/5$

$w = 16.6$

16.6 implies about 17 weeks, because 16.6 approximates to 17

Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks
