1 answer:

5 0

(x+3)(2x-6)=26

2x(to the second power)-18=26

2x(to the second power) -18-26=26-26

2x(to the second power)-44 = 0

x=square root of 22,x= negative square root of 22

decimal form : x = 4.69042,x= -4.69042

In the United States, 30% of people own a cat and 3% of people own a bird. What is the probability of someone owning both a cat

Alex777 [14]

Answer: 9/100

Step-by-step explanation:

Probability of people own a cat:

P(cat)=30/100=0.3

Probability of people own a bird:

P(bird)=3/100=0.03

Probability of both own a cat and a bird

P(cat and bird)=(30/100) × (3/100)

=90/1000=9/100=9%

The angles measures x and 4x are complementary angles. Which is the value of x?

Hitman42 [59]

Answer:

The angles measures x and 4x are complementary angles. The value of x is 36 degrees

Solution:

Given, two angles are x and 4x

We have to find the value of above given x

We are also given that, given two angles are complementary angles for each other

So, we know that, sum of any two complementary angles will always be equal to 180 degrees

Then, in the problem given,

$x+4 x=180 \rightarrow 5 x=180 \rightarrow x=\frac{180}{5} \rightarrow x=36$

Hence the angles measures x and 4x are complementary angles. The value of x is 36 degrees

N76 [4]

To get the height to the nick we use the trigonometry formula:
tan θ=opposite/adjacent
θ=73°
opposite=h ft
adjacent=38 ft
plugging our values we get:
tan 73=h/38
thus
h=38 tan 73
h=124.29~124.3 ft

Answer: C. 124.3 ft
