Step-by-step explanation:

volume of sphere = 288

based on formula, V = 4/3πr³

288 = 4/3(3.14)r³

288 = 4.187(r³)

r³ = 288/4.187

r =

$\sqrt[3]{68.78}$

r = 4.09

= 4.1

Solve for x.<br><br> −4/5x+3/10<8/10

Genrish500 [490]

Answer:

for (−4/5)x + 3/10 < 8/10: solution is x > -5/8

for −4/(5x) + 3/10 < 8/10: solution is x > -8/5

Step-by-step explanation:

I'm not exactly sure if you mean -4 divided by 5x or (-4/5)x, so I've done both! :)

$-\frac{4}{5}x+ \frac{3}{10} < \frac{8}{10}$

subtract 3/10 from both sides: $-\frac{4}{5}x < \frac{5}{10}$

Divide both sides by 4/5: $-x < \frac{5}{8}$

Divide both sides by -1 (reverse sign): $x > -\frac{5}{8}$

$-\frac{4}{5x}+ \frac{3}{10} < \frac{8}{10}$

subtract 3/10 from both sides: $-\frac{4}{5x} < \frac{5}{10}$

Multiply both sides by 5x: $-4 < \frac{5}{2}x$

Divide both sides by 5/2: $x>- \frac{8}{5}$

Malcolm and Theo's families are both traveling to the same vacation resort.

snow_tiger [21]

Answer:

Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

<em>See attachment for complete question</em>

Given

Malcom's Family:

$d = 65t$

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

$t = 1; d = 50$

$t = 2; d = 100$

First, we determine the slope, m:

$m = \frac{d_2 - d_1}{t_2 - t_1}$

$m = \frac{100 - 50}{2- 1}$

$m = \frac{50}{1}$

$m = 50$

Next, we determine equation for Theo's family using:

$d - d_1 = m(t - t_1)$

$d - 50 =50(t - 1)$

$d - 50 =50t - 50$

Add 50 to both sides

$d - 50 +50=50t - 50 + 50$

$d =50t$

So, we have the following:

$d = 65t$ --- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

$d =50t$ --- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

$Rate = 65t - 50t$

$Rate = 15t$

<em>Which implies that Malcom's family travel 15 miles per hour faster than Theo's</em>
