If our galaxy were 1m wide, what would the distance to the Andromeda Galaxy be?

Setler79 [48]

Answer:

25 m

Step-by-step explanation:

The scale factor is

1 : 9.5×10²⁰ as we make our galaxy as small as 1 m.

The distance to Andromeda would be:

2.4×10²² * 1/9.5×10²⁰ =
2.4/9.5×10²²⁻²⁰ =
0.25×10² =
25 m

The missing term in the denominator is

Margaret [11]

$\frac{7^{16} }{7^{12} }= \frac{7^{16-34} }{7^{12-34} } =\frac{7^{-18} }{7^{-22} } = 2401$

so the missing term in the denominator is 7^(-22)

ok done. Thank to me :>

Walt received a package that is 2 1/3 inches long, 6 ¾ inches high, and 8 ½ inches wide. What is the surface area of the package

Umnica [9.8K]

The surface area of prism is 185.815 square inches

Solution:

Given that,

$Length = 2\frac{1}{3}\ inches = \frac{3 \times 2 + 1}{3} = \frac{7}{3}\ inches = 2.33\ inches$

$Width = 8\frac{1}{2}\ inches = \frac{17}{2}\ inches = 8.5\ inches$

$Height = 6\frac{3}{4}\ inches = \frac{27}{4}\ inches = 6.75\ inches$

The surface area of package is given as:

$A=2(wl+hl+hw)$

Where,

"l" is the length

"w" is the width

"h" is the height

Substituting the values we get,

$A = 2((8.5 \times 2.33) + (6.75 \times 2.33) + (6.75 \times 8.5))\\\\Simplify\ the\ above\ equation\\\\A = 2(19.805+15.7275+57.375)\\\\A = 2 \times 92.9075\\\\A = 185.815$

Thus the surface area of prism is 185.815 square inches
