sasho [114]

Answer: BC=18

DG=6

Step-by-step explanation: well we have to use similarity. and that means setting up proportions so... 15/10 = BC/12 10BC=180, BC=18

9/18=DG/12 (we put 18 because it equals BC)

hope this helped!!

Simplify the expression. (0.4x10^-6)(0.7x10^-2)

harina [27]

Answer:

2.8 · 10^(-9)

Step-by-step explanation:

I'd suggest you do this problem through two separate multiplications:

First, 0.4·0.7 = 0.28, or 2.8 · 10^(-1)

Second, 10^(-6) · 10^(-2) = 10^(-8), and so the final result is

2.8 · 10^(-1) · 10(-8) = 2.8 · 10^(-9)

Please note: negative exponents (such as -9, above) should be enclosed in parentheses for added clarity.

It takes Emily eight hours to paint her house. Mike can paint the same area in nine hours. Find how long it would take them if t

emmasim [6.3K]

It will take them 4.24 hours together to paint the area together

Step-by-step explanation:

If Emily takes eight hours to paint the area then she will paint 1/8 of the house in one hour

Similarly, if Mike can paint the same area in 9 hours, then he will paint 1/9 of the same area

Let x be the number of hours in which they will together paint the area.

If x hours are taken by them to paint the area then 1/x of the area will be painted in one hour

So,

$\frac{1}{8}+\frac{1}{9}=\frac{1}{x}\\Multiplying\ both\ sides\ with\ the\ LCM\\72x\\(72x)*\frac{1}{8}+(72x)*\frac{1}{9}=72x * \frac{1}{x}\\9x+8x=72\\17x=72\\Dividing\ both\ sides\ by\ 17\\\frac{17x}{17}=\frac{72}{17}\\x=4.24\ hours$

It will take them 4.24 hours together to paint the area together
