Answer:

116

Step-by-step explanation:

supplementary angels : angle a + angle b= 180

p + q =180

p + 64 =180(cuz q=64)

p = 180 - 64

p = 114

The polygons in each pair are similar. Find the missing side length.

Taya2010 [7]

Answer:

Step-by-step explanation:

If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.

Now use that scale factor, 4/5, to find the missing length

4/5 = ?/15

5*3 = 15 so 4*3 = ?

? = 12

(3.6x10^-5)÷(1.8x10^2) in standard form

Lerok [7]

Answer:

The standard form of $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ is 0.0000002

Solution:

We have to write $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ in standard form.

$=\frac{3.6 \times 10^{-5}}{1.8 \times 10^{2}}$

By dividing 3.6 by 1.8 we get “2”, hence the above equation becomes,

$=\frac{2 \times 10^{-5}}{10^{2}}$

We know that $\frac{x^{a}}{x^{b}}=x^{a-b}$

Therefore the above equation becomes,

$=2 \times 10^{-5-2}$

$=2 \times 10^{-7}$

since the exponent of 10 is negative , therefore 7 zeros are written on the left hand side of the number.

= 0.0000002

Hence the standard form of $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ is 0.0000002

are any two regular polygons similar. The area of the smaller figure is about 390 cm^2. choose the best estimate of the area of

galben [10]

Answer:

The best estimate of the area of the larger figure is $693\ cm^{2}$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

x-----> the corresponding side of the larger figure

y-----> the corresponding side of the smaller figure

$z=\frac{x}{y}$

we have

$x=12\ cm$

$y=9\ cm$

substitute

$z=\frac{12}{9}=\frac{4}{3}$ -----> the scale factor

step 2

Find the area of the larger figure

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z----> the scale factor

x-----> the area of the larger figure

y-----> the area of the smaller figure

$z^{2}=\frac{x}{y}$

we have

$z=\frac{4}{3}$

$y=390\ cm^{2}$

substitute and solve for x

$(\frac{4}{3})^{2}=\frac{x}{390}$

$(\frac{16}{9})=\frac{x}{390}$

$x=390*16/9=693.33\ cm^{2}$

Asian has 4 dogs each dog eats 2 cups of dog food per day a bag of dog food lasts Asian 12 days . How many total cups of food ar

sashaice [31]

Answer:

112

Step-by-step explanation:

4 dogs times 2 cups = 8 cups. 8 cups times 12 days = 96 cups in bag. 96 plus two days worth (16) = 112

Hope this helps!

p.s. you could just do 8 times 14, but that's not as fun. ;)
