Answer:
d = 16, b = 73
Step-by-step explanation:
To find b, i knew that the angles were congruent, so they were both the exact same.
To find d, I knew that the 65 degrees and the missing value of d had to add up to 81 degrees, because those are congruent too. So, I just subtracted 65 from 81 and then I got the answer.
I hope I helped.
Brainliest would be appreciated.

divide each term on the numerator by 7b
= - 7
/ 7b + 42
/ 7b
= -

The number of people increased by 2.
This means as a ratio it is now 6/4 as many as originally planned.
6/4 can be reduced to 3/2.
The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.
This means the length of time the food lasts is reduced by 1/3, which is 33.3%
Answer:
- P = -390t +48,000
- P = 43,710 in 2003
Step-by-step explanation:
A) We are given two pairs of (t, P): (0, 48000), (8, 44880). We can use these with the 2-point form of the equation of a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (44880 -48000)/(8 -0)(t -0) +48000
P = -3120/8t +48000
P = -390t +48000
__
B) In 2003, t = 11, so we have ...
P = -390(11) +48000 = 43710
The population in 2003 is predicted to be 43,710.
Answer:
1024/59049
Step-by-step explanation:
P( clear hurdle) = 2/3
There are 10 hurdles
P ( clear all hurdles) = P( clear hurdle) * P( clear hurdle)...... 10 times
= 2/3 * 2/3 *....... 10 times
= (2/3) ^ 10
=1024/59049
