3 10 in . = 7 8 mi . what is the unit rate
Sav [38]

Answer: (3/10) in = (7/8) mi

1 in = (7/8) mi ÷ (3/10)

      = 7/8 * (10/3) = 70/24

1 in = (70/24) mi

It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.  

Hope this helps :)

If you take 608 x 8
Your gonna have to do 8x8 first equals 64 so drop the 4 & carry the 6
Next youd do 0x8 which equals 0 but since you carried the 6 youd have to add the 6 to the 0 which equals 6 so youd drop the 6
Then finally youd multiply 8x6 which is 48 and theres nothing to carry over too so youd drop the whole number , all together it makes this answer 4,864

Change the followong decimals to percents and order them on the number line from least to gratest useing this numbers 0.02 ' 0.9
olganol [36]

Answer:

2%

15%

25%

90%

Step-by-step explanation:

To turn decimals to percents, you just have to times them by 100 or you can just do the quick way and move the decimal 2 places to the right.

0.02*100 = 2%

0.9*100 = 90%

0.25*100 = 25%

0.15*100 = 15%

Then, you just put them in order:

2%

15%

25%

90%

Find all x such that the distance between (-6,-6) and (x,-5) is 19.
amm1812

\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-6}~,~\stackrel{y_1}{-6})\qquad (\stackrel{x_2}{x}~,~\stackrel{y_2}{-5})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{d}{19}=\sqrt{[x-(-6)]^2+[-5-6]^2}\implies 19=\sqrt{(x+6)^2+(-11)^2} \\\\\\ 19^2=(x+6)^2+(-11)^2\implies 361 = (x^2+12x+36)+121 \\\\\\ 361=x^2+12x+157\implies 0=x^2+12x-204 \\\\[-0.35em] ~\dotfill

\bf ~~~~~~~~~~~~\textit{quadratic formula} \\\\ 0=\stackrel{\stackrel{a}{\downarrow }}{1}x^2\stackrel{\stackrel{b}{\downarrow }}{+12}x\stackrel{\stackrel{c}{\downarrow }}{-204} \qquad \qquad x= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}

\bf x = \cfrac{-12\pm\sqrt{12^2-4(1)(-204)}}{2(1)}\implies x = \cfrac{-12\pm \sqrt{144+816}}{2} \\\\\\ x = \cfrac{-12\pm \sqrt{960}}{2}\implies x = \cfrac{-12\pm \sqrt{8^2\cdot 15}}{2}\implies x = \cfrac{-12\pm 8\sqrt{15}}{2} \\\\\\ x = -6\pm 4\sqrt{15}\implies x \approx \begin{cases} 9.49\\ -21.49 \end{cases}
