Answer: The answer is 4000 in. sq.

Step-by-step explanation:

To find the surface area of a rectangular prism you follow the formula SA = 2(wl+hl+hw) However, with this question we must scale the values up by 10. We do this by multiplying them by 10. The original values were 6, 2, and 1. The new ones are 60, 20, and 10. Now all we do is plug them into the formula.

See :

SA = 2(wl+hl+hw) SA = 2 (20 · 60 + 10 · 60 + 10 · 20)

This may look scary but once you simplify it, it looks like this :

SA = 2(1200+600+200)

SA = 2(2000)

SA = 4000

Answer:

Area: $\frac{8}{15}$ feet²

Perimeter: $\frac{44}{15} =2 \frac{14}{15}$ feet

Step-by-step explanation:

The formula of finding the area of a rectangle or square is width multiplied by length.

The formula of find the perimeter of a rectangle or square is width+width+length+length

Area: $\frac{4}{5} *\frac{2}{3} = \frac{8}{15}$ feet²

Perimeter:

$\frac{4}{5} +\frac{4}{5} +\frac{2}{3} +\frac{2}{3} =$

$\\\\\frac{12}{15} +\frac{12}{15} +\frac{10}{15} +\frac{10}{15} =\\\\\frac{24}{15} +\frac{20}{15} =\\$

$\frac{44}{15} =2 \frac{14}{15}$

Radio signals travel at a rate of 3 × 108 meters per second. How many seconds will it take for a radio signal to travel from a s

lys-0071 [83]

Answer:

1.1888 (8 goes on forever) seconds to travel from the satellite to Earth.

Step-by-step explanation:

It is traveling at 3 x 108 m/s and needs to travel 3.6 x 107 m. 3 x 108=324 and 3.6 x 107=385.2 so 324 m/s for 385.2 m. 385.2/325=1.1888.

Boston, Massachusetts had a population of 617,594 people during January 1 2010, and 675,647 people on January 1 2020.

tigry1 [53]

Answer:

See below

Step-by-step explanation:

Exponential function is:

y = abˣ

If we consider the time difference in years as x and the initial population as a, then we get:

675647 = 617594*b¹⁰

Find the value of b:

b¹⁰ = 675647/617594
b¹⁰ = 1.09399864636
b = 1.09399864636^(1/10)
b = 1.009 (rounded)

The equation we got is:

y = 617594*1.009ˣ

Here we have y- population after x years since 2010, x - the number of years since 2010 and 1.009 is the population growth rate.
