this year Benny is 12 years old and his mom is 48 years old what percent of his mom's age is Benny's age

Lady bird [3.3K]

Answer:

25%

Step-by-step explanation:

Let's set up a percent proportion:

12/x = 48/100

To solve for x, we would do:

x = (12*100)/48 = 1200/48 = 25

x = 25%

In my opinion, the easiest way to do this would be to look at this and notice that 12 * 4 =48 so that means 12 is 1/4 of 48 and 1/4 = 25%.

Let me know if you have any questions.

Solve for x. Round to the nearest tenth of a degree, if necessary.

babymother [125]

Answer:

x ≈ 40.0°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = $\frac{opposite}{adjacent}$ = $\frac{WX}{VW}$ = $\frac{57}{68}$ , then

x = $tan^{-1}$ ( $\frac{57}{68}$ ) ≈ 40.0° ( to the nearest tenth )

A particular automatic sprinkler system has two different types of activation devices for each 3 sprinkler head. One type has a

zmey [24]

Answer:

There is an 85% probability that the sprinkler head will be activated.

Step-by-step explanation:

We have these following probabilities:

50% of the first sprinkler being triggered

90% of the first sprinkler being reliable

50% of the second sprinkler being triggered

80% of the second sprinkler being reliable.

What is the probability that the sprinkler head will be activated?

$P = P_{1} + P_{2}$

$P_{1}$ is the probability of the first sprinkler being triggered and activated. So:

$P_{1} = 0.5*0.9 = 0.45$

$P_{2}$ is the probability of the second sprinkler being triggered and activated. So:

$P_{2} = 0.5*0.8 = 0.40$

$P = P_{1} + P_{2} = 0.40 + 0.45 = 0.85$

There is an 85% probability that the sprinkler head will be activated.
