An auto mechanic converts a metric part to 0.492 in. The part comes only in fractional sizes given to the nearest 64th of an inc
tatuchka [14]

Answer:

the closest part the mechanic can chose is 0.5 inch

Step-by-step explanation:

fractional sizes given to the nearest 64th of an inch = 1/64 = 0.0156

the closest size to 0.492in = 0.492 + 0.0156 = 0.5076 inches

approximately, the closest part the mechanic can chose is 0.5 inch

Please solve <br> -(6x+7)+8=19
JulijaS [17]
-6x-7+8=19 and then add your like terms so it’s -6x+1=19 and then subtract one on both sides so it’s -6x=18 so x=-3

Line j has an equation of y - 8 = -2/3(x+5). Line K is perpendicular to line j and passes + through (-6, -2). What is the equati
riadik2000 [5.3K]

Answer:

y = \frac{3}{2} x + 7

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

y - 8 = - \frac{2}{3} (x + 5) ← is in point- slope form

with m = - \frac{2}{3}

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{2}{3} } = \frac{3}{2}

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept ) , then

y = \frac{3}{2} x + c ← is the partial equation

to find c substitute (- 6, - 2 ) into the partial equation

- 2 = - 9 + c ⇒ c = - 2 + 9 = 7

y = \frac{3}{2} x + 7 ← equation of line K

Help please!!! asap! 10 points!
Anna11 [10]

Answer:

Fr^2/Gm_2=m_1

Step-by-step explanation:

What you do first is you have to cross-multiply so f*r^2 and 1*gm_1m_2 to get

Fr^2=Gm_1m_2. Next you will divide Gm_2 from both sides to get

Fr^2/Gm_2=m_1 as your answer.

Please don't take this down, it's just an innocent question
hichkok12 [17]

Answer:

False

Step-by-step explanation:

You can only get a two by rolling 2 ones

you can get a three by rolling a 1 and 2

They both only have 1 option to roll on too. So the answer is false, with 2 die the probibility will be the same.
