Select all of the scales that are equivalent to 3 cm to 4 km.
ra1l [238]

In mathematics, a scale can be described in charts as a marking system at predefined times, which determines the relationship between the units that are being used and their images on the graph, and the further calculation can be defined as follows:

  • Since in this question, the ratio is between 3 cm to 4 km you can make a \bold{\frac{3}{4}=\frac{cm}{km}} split, and if you are split between 3 and 4, you get the ratio between \bold{\frac{\frac{3}{4 \ cm}}{1\ km} = \frac{3\ cm}{ 4\ km}}.

         \bold{\to \frac{3 }{ 4}= 0.75}

Therefore the final answer is "0.75 cm to 1 km"

Help please! <br> This question needs a bit of a hand.
worty [1.4K]

Answer:

It's not a right angle.

Step-by-step explanation:

Remark

There's a second restriction on the problem. The Perimeter is 22 cm.

AB = 8

BC = 5

AC = 9.4

When you add these up, you get 8 + 5 + 9.4 which is 22.4

You may think this is close enough. In this case it is not. Either the perimeter has to 22.4 or the hypotenuse has to be reduced. Let us say it is close, but not close enough.

When you use other methods, you find out that the right angle is actually 90.4 degrees

Enter the slope-intercept equation of the line that has a slope of -5 and y-intercept (0,8)
Genrish500 [490]

Slope-intercept form is y = mx + b, where the variable m represents the slope of the line and the variable b represents the y-intercept. Because we are given these values, all we have to do is plug in the given values into the equation for their respective variables.

y = mx + b

y = -5x + 8

Therefore, your answer is y = -5x + 8.

Hope this helps!
