Nina [5.8K]3 years ago

5 0

Answer:

Step-by-step explanation:

If r=2, that means that each term in the geometric sequence is multiplied by 2.

So, if r=2, and the sixth term in the sequence is 96, then simply divide by 2 until you get to the first term.

Which is 3.

Jaden drove 200 miles in 4 hours. At this speed, how long with it take him to drive 300 miles? How long will it take him to driv

Kisachek [45]

Answer:

10 hours to drive 500 miles

6 hours to drive 300 miles

Step-by-step explanation:

Hi, to answer this we have to calculate the speed rate first:

Speed = distance /time

Speed = 200 miles / 4 hours = 50 miles per hour

So, to find the time for each number of miles:

Time = distance /speed

For 500 miles:

t = 500/50 = 10 hours

For 300 miles

t = 300/50 =6 hours

So, in conclusion:

It will take 10 hours to him drive 500 miles

It will take 6 hours to him drive 300 miles

A direct variation exist between x and y. When x=4, y=3. What is the value of y when x=10

scoray [572]

Answer:

$y = 7.5$

Step-by-step explanation:

Given

Direct variation implies that:

$y = kx$

Where k is the constant of variation.

$x=4; y=3$

Required

Find y when $x = 10$

$y = kx$

Make k the subject

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

For: $x=4; y=3$

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

For: $x = 10$

$k = \frac{y}{x}$ becomes

$k = \frac{y}{10}$

Substitute $k = \frac{3}{4}$

$\frac{3}{4} = \frac{y}{10}$

Make y the subject

$y = \frac{3}{4} * 10$

$y = \frac{3* 10}{4}$

$y = \frac{30}{4}$

$y = 7.5$
