Hello! based on this problem, 68 is component of a whole. To solve it, we have the right to write and also solve a proportion. Set it up like this:

68/x = 85/100

Cross main point the sections. 68 * 100 is 6,800 and also 85 * x is 85x. Therefore you acquire 6,800 = 85x. Now, division each side by 85 to isolate the x. 85x/85 cancels out. 6,800/85 is 80. Us can check this sdrta.net by multiply 80 by 85%. 80 * 85% (0.85) is 68. There"s our sdrta.net. 68 is 85% the 80.

You are watching: 68 is 85 of what number




what is the equation of the line the is parallel come the line y=-1/3x+4 and passes with the point(6,5)

sdrta.net:

y= -1/3x+7

Step-by-step explanation:

Lines that room parallel have the exact same slope. Thus the heat of the equation the you room finding has the slope = -1/3 and an unknown value we can call b to produce the equation y=-1/3x +b.

Using the point which the line must pass (6,5), we have the right to plug x and y into the unknown equation to resolve for b, the y-intercept.


5=-1/3(6)+b

5=-2+b

7=b



Dbecause girlfriend can’t add or subtract unequal terms for A and B an interpretation the equations wouldn’t change for C it would be 10x-15y no -3y D) x+y+x+y=2x+2y 2(x+y)= 2x+2y

Anna has a house with a industry value the $120,000 if the assessment price is 40% and the tax rate per $100 is $2.35 exactly how much will
The house is $120,000the assessment price is 40% that $120,000 making that $48,000and for every $100 over there is a taxes of 2.35 make the tax equal $2,820add the all up and the total is $170,820

Wires manufactured for use in a computer system system room specified to have actually resistances in between .12 and .14 ohms. The actual measured

sdrta.net: a) 0.9544996

b) 0.9999366

Step-by-step explanation:

Given : The actual measured resistances of wires created by company A have actually a common probability circulation with mean

*
ohm and standard deviation
*
ohm.

Wires produced for usage in a computer system system room specified to have resistances between .12 and .14 ohms.

Let x it is in the random variable the represents the worth of resistance in wires.

Using formula for z-score ,

*

The z-value at x= 0.12 will certainly be

*

The z-value at x= 0.14 will certainly be

*

The p-value :

*

*

Hence, the probability the a randomly selected wire from firm A’s production will accomplish the specifications = 0.9544996

b) Sample dimension : n= 4

Using formula because that z-score ,

*

The z-value in ~ x= 0.12 will certainly be

*

The z-value in ~ x= 0.14 will be

*

The p-value :

*

*

The probability that all 4 in a randomly selected mechanism will meet the specifications = 0.9999366
