Answer:

Step-by-step explanation:

log3^(2x+3) = log243

(2x+3)log3 = log243

2x+3 = log243/log3

2x = (log243/log3)-3

x = [(log243/log3)-3]/2

x = (5-3)/2

x = 2/2

x = 1

Check:

3^2(1)+3 = 243

3^2+3 = 243

3^5 = 243

3×3×3×3×3 = 243

9×9×3 = 243

81×3 = 243

243 = 243

Emily leaves her house at exactly 8:25 a.m. to bike to her school, which is 3.42 miles away. When she passes the post office, wh

mafiozo [28]

First, let's find out the number of minutes Emily has to get to school. From 8:25 to 8:50, there are 25 minutes.

Next, let's find out the number of minutes before Emily looks at her watch. From 8:25 to 8:28.50, there are 3.5 minutes.

Now let's calculate Emily's speed in miles per minute. To do so, divide the distance traveled by the time it took:

$\frac{0.75}{3.5}$ miles/minute

Now let's calculate how far Emily can travel in 25 minutes going this speed. To do so, we multiply her speed by the time traveled:

$\frac{0.75(25)}{3.5} =5.357$ miles

5.357 miles is greater than 3.42 miles, so yes, Emily will make it to school on time.

qaws [65]

Answer:

90428160.3 ft³

Step-by-step explanation:

The question is on volume of a pyramid with a square base

The formulae for volume of a pyramid is V=( l×w×h)/3

where l is length of pyramid base, w is width of pyramid base and h is the height of the pyramid

The pyramid has a square base thus l=w= 751 feet

The height of the pyramid is h=481 feet

v= (751×751×481)/3

v=90428160.3 ft³
