The exact answer is 34.1754
To get an approximate answer, to convert km to miles, you cut the km in half, then cut that into quarter. You will get 27.5 for the half, and 6.875 for the quarter of that. Then you add the two together, which would give you  34.375.

Im trash at math sorry
balu736 [363]

Answer:

Step-by-step explanation:

Use vertical angles to help solve the problem. Angles that are across from each other are congruent. For exmaple,  <2 = 85 degrees because the angle across from it is 85 degrees. I assume angle 1 is 95 degrees, so angle 3 would also be 95 degrees.

Here are two sets of numbers, a and b. Set a :200,104,100,160. Set b: 270,400,483,300, x. Mean of set a: mean of set b= 3:8. Wor
LenKa [72]

Given:

The given sets are:

Set a : 200, 104, 100, 160.

Set b: 270, 400, 483, 300, x.

Mean of set a: mean of set b= 3:8

To find:

The value of x.

Solution:

Formula for mean:

Mean=\dfrac{\text{Sum of observations}}{\text{Number of observation}}

The mean of set of a is:

Mean=\dfrac{200+104+100+160}{4}

Mean=\dfrac{564}{4}

Mean=141

The mean of set of b is:

Mean=\dfrac{270+400+483+300+x}{5}

Mean=\dfrac{1453+x}{5}

Mean=\dfrac{1453+x}{5}

It is given that,

Mean of set a: mean of set b= 3:8

\dfrac{141}{\dfrac{1453+x}{5}}=\dfrac{3}{8}

\dfrac{705}{1453+x}=\dfrac{3}{8}

8\times 705=3\times (1453+x)

5640=4359&#10;+3x

Isolate the variable x.

5640-4359&#10;=3x

1281&#10;=3x

Divide both sides by 3.

\dfrac{1281}{3}&#10;=x

427&#10;=x

Therefore, the value of x is 427.

Solve by substitution <br>-4x-2y=-12 <br>4x+8y=-24
kykrilka [37]
I hope this helps you



-4x-2y+4x+8y= -12-24



6y= -36


y= -6



-4x-2. (-6)= -12


-4x+12= -12


-4x= -24


x=6


(6, -6)

What is the y-intercept of the line perpendicular to the line...
Dominik [7]

Answer:

D) 5

Step-by-step explanation:

Perpendicular lines have opposite reciprocal slopes.

The line: y=\frac{3}{4} x+3 has a slope of \frac{3}{4} as it is  in y=mx+b form, where m is the slope, and b is the y-intercept.

Since the slope is \frac{3}{4}, we see that the negative reciprocal slope is -\frac{4}{3}, as \frac{4}{3} is the reciprocal (flip the numerator and denominator).

From here, we can use point slope form: y - y1 = m(x- x1), where (y1, x1) is  the point. In this case, (3, 1) is the point.

Thus, we have: y-1 =-\frac{4}{3}(x-3) as our final equation.

Simplifying: y-1 = -\frac{4}{3}x+4

And: y=-\frac{4}{3}x+5, which gives us the y-intercept to be 5.

Let me know if this helps!
