Answer:

c (all real numbers)

Step-by-step explanation:

The first inequality has the solution ...

3 + v ≤ -4

v ≤ -7 . . . . . . . subtract 3 from both sides

The second inequality has the solution ...

-2v ≤ 14

v ≥ -7 . . . . . . . divide by -2. Division by a negative reverses the inequality

So, the solution to the compound ...

v ≤ -7 or -7 ≤ v

is every number — <em>all real numbers</em>. The graph of that is the entire number line, as in choice C.

How long would it take a car with a top speed of 203 mph to travel 12.42 miles up a slope of 6.4% accelerating at 0.091 G's (2.9

Nadusha1986 [10]

Answer:

319 seconds

Step-by-step explanation:

The distance 12.42 miles is equivalent to

12.42*5280=65577.6 ft

$ma-mgsin\theta=ma_{net}
$

When slope is 6.4%, $\theta=tan^{-1} 0.064=3.67^{\circ}
$

$a_{net}=a-gsin\theta=2.93-32.2sin3.67=-0.87
$

Therefore, $a_{net}=-0.87 ft/s^{2}
$

Also

$s=ut+0.5a_{net}
$

$65577.6=297.73t+0.5(-0.87)t^{2}
$

$0.87t^{2}-297.73t+6577.6=0
$

Making t the subject of the formula by solving quadratic equation

t=318.4791278210496

Therefore, time is 319 seconds

harry bought 155 ranges for $35. He found that 15 of them were rotten. He sold all the remaining oranges at 7 for $2. How much d

Nesterboy [21]

Answer:

Harry made $5.

Step-by-step explanation:

First 155 minus 15 rotten oranges is 140 oranges. Then, you do 140 divided by 7 to find the number of sales he made. 140 divide by 7 equals 20 which is the number of sales. Then 20 times 2 equals $40. Since he spent $35 to buy the oranges at first, you do 40 minus 35 which equals 5. He made $5 profit.

Approximately 1,870,000 oz of gold went into the manufacturing of electronic equipment in a certain country in 1 year. This was

Alexxandr [17]

Answer: 17000000 ounces of gold were mined in that country that year.

Step-by-step explanation:

Let x represent the number of ounces of gold that were mined in that country that year.

Approximately 1,870,000 oz of gold went into the manufacturing of electronic equipment in a certain country in 1 year. This was 11% of all the gold mined in that country that year. This means that

11/100 × x = 1870000

0.11x = 1870000

x = 1870000/0.11

x = 17000000

the perimeter of a triangle is 51cm. The lengths of its side are x cm, x+2 cm, and x+4 cm. what is the length in cm of the longe

Neko [114]

Answer:

19 cm

Step-by-step explanation:

The perimeter is 51cm

The side lengths are x, x+2, and x+4

To find perimeter, we add all the side lengths.

Therefore, the equation we would use is the following:

x + x+2 + x+ 4 = 51

Then we solve for x

3x + 6= 51

Subtract 6 on both sides

3x = 45

divide by 3

x=15

Now, x is the smallest side, and we are trying to find the longest side,

So we plug in x for the longest length:

(15) + 4= 19

19cm is the longest side of the triangle.
