Answer:

(B)25

Step-by-step explanation:

From the given diagram:

\angle ACE$ and \angle ECB are on a straight line, and we know by the Linear Postulate that the sum of angles on a straight line is 180 degrees.

Therefore:

\angle ACE$ + \angle ECB=180^\circ$ (Linear Postulate)\\(2x+2)^\circ+(5x+3)^\circ=180^\circ\\$Collect like terms\\2x+5x+2+3=180\\7x+5=180\\$Subtract 5 from both sides\\7x+5-5=180-5\\7x=175\\$Divide both sides by 7\\7x\div 7=175\div 7\\x=25^\circ

The correct option is B.

A Japanese beetle has length between 0.3 and 0.5 inches.Find two lengths that are within the given span. Write them as fraction
Wittaler [7]
<span>A Japanese beetle’s length are equals to
=> 0.3 inches
=> 0.5 inches

Now let’s find the length that is between the span of the two given length:
But before that let’s convert the 2 given numbers in decimal points to fraction:
=> 0.3 = 3/10
=> 0.5 = 5/10

Find the fraction between the given 2 numbers:
=> 0.3
=> 0.4
=> 0.5

Therefore the number we are looking 0.4
=> 0.4 = 4/10
Now, we have the complete length of Japanese beetles, the 0.3, 0.4 and 0.5</span>

A country x has a population growth rate of 3%. how many years will it take the population of country x to double? use continuou
Kaylis [27]
A=Pe^{rt}
A=future amount
P=present amount
r=rate in decimal
t=time in years

so
when will A=double of original?
or when will A=2P

r=3%=0.03
t=t

A=Pe^{(0.03)t}
2P=Pe^{0.03t}
divide both sides by P
2=e^{0.03t}
take ln of both sides
ln(2)=ln(e^{0.03t})
ln(2)=0.03t ln(e)
ln(2)=0.03t (1)
ln(2)=0.03t
divide both sides by 0.03
(ln(2))/0.03=t
use calculator
23.1049=t
so a little over 23 years, about 23 years and 38.2 days
