Answer:

The length of the ramp is 7.3 meters.

Step-by-step explanation:

The length of a triangle's side must be less than the sum of its two other sides. It also cannot have the same value as its other combined sides.

7 + 2 > 7.3

2 + 7.3 > 7

7 + 7.3 > 2

r is also longer than 7 meters, so that leaves option b. as your answer.

A recent survey found that 80.5% of households has Internet access and 82% of households had cable television. Also, it was repo

kirill115 [55]

Answer: 0.878

Step-by-step explanation:

Given : P( Internet access) = 80.5%= 0.805

P(cable television) = 82% = 0.82

P( Internet access and cable television) = 74.7% =0.747

Formula: P(A or B)= P(A ) + P(B) - P(A and B)

So, P( Internet access or cable television) = P( Internet access) + P(cable television) -P( Internet access and cable television)

= 0.805+0.82-0.747

= 0.878

The probability that a randomly selected household in the survey had either Internet access or cable = 0.878

Which inequality is true when n=4?

Nadusha1986 [10]

To find out which inequality is true, we need to plug in n=4.

$2n>6$
$2(4)>6$
$8>6$

And since 8 is really greater than 6, this inequality is true! :)

$n+3$
 $4+3 < 7$
$7 < 7$

7 is not less than 7. So this inequality is false.

$9- n \geq 13$
$9-4 \geq 13$
$5 \geq 13$

5 is not greater than or equal to 13, so this inequality is false

$\frac{n}{12} \geq 3$
$\frac{4}{12} \geq 3$
 $\frac{1}{3} \geq 3$

And 1/3 is not greater than 3, so this inequality is also false.
