Gulf gully and jump rope road are a pretty far distance.If the scale for the map is 0.5 inches=2.3 miles,what is the actual dist

mezya [45]

Answer:

12 cm = 21.62 miles

6 cm = 11.04 miles

Step-by-step explanation:

To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of $\frac{map}{real world}$ and simplify.

We know $\frac{map}{real world}=\frac{0.5in}{2.3 miles}$ . We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write $\frac{4.7in}{xmiles}$ and $\frac{2.4in}{xmiles}$

We set them equal.

$\frac{0.5}{2.3}=\frac{4.7}{x}$

and

$\frac{0.5}{2.3}=\frac{2.4}{x}$

To solve each proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

$2.3(4.7)=0.5(x)\\10.81=0.5x\\\frac{10.81}{0.5}=\frac{0.5x}{0.5} \\21.62 miles=x$

and

$2.3(2.4)=0.5(x)\\5.52=0.5x\\\frac{5.52}{0.5}=\frac{0.5x}{0.5} \\11.04 miles=x$

1.Find x,y and z in the figure. 2. find the x and y in the figure

STALIN [3.7K]

$\\ \sf\longmapsto x+2x+90=180$

$\\ \sf\longmapsto 3x+90=180$

$\\ \sf\longmapsto 3x=180-90$

$\\ \sf\longmapsto 3x=90$

$\\ \sf\longmapsto x=\dfrac{90}{3}$

$\\ \sf\longmapsto x=30$

Now

$\\ \sf\longmapsto x=2y$ (Opposite interior angles)

$\\ \sf\longmapsto 2y=30$

$\\ \sf\longmapsto y=\dfrac{30}{2}$

$\\ \sf\longmapsto y=15$

And

$\\ \sf\longmapsto x+z=180$

$\\ \sf\longmapsto z+30=180$

$\\ \sf\longmapsto z=180-30$

$\\ \sf\longmapsto z=150$

Determine if each table shown below represents a function or not ?

yarga [219]

Neither of them are functions. Functions cannot have two of the same numbers in the x value, and since the first table has two 5s in the x column and the second table has two 7s, neither of them can be functions.

Hope this helps :)
