let x be how far up the wall ladder reaches

by Pythagoras theorem

x^2+5^2=13^2

x^2 =(13^2)-(5^2)

x= square root of 144

x= 12 or x =-12(rej,x>0)

hence ladder reaches 12 foot up the wall

There are two bags: a bag with 4 blue marbles and 6 black marbles and another one containing 6 blue marbles and <span>6 black marbles. the probability of getting a blue marble in the first bag is 6/10 or 3/5 while that on the second bag is 6/12 or 1/2. Hence the total probability of getting two marbles is c. 3/10. </span>

PLEASE helppp. What equation describes a line that is perpendicular y=-2/7x+5 and has the same y-intercept as y = 3x - 2?
svp [43]

Answer:

y = 7/2 -2

Step-by-step explanation:

if the slope of the first problem is -2/7 then its perpendicular is 7/2 (the exact opposite) and since the y- intercept is the b in Y= mx +b the intercept of the equation you’re trying to find is -2
