Answer:

w=74/45

Step-by-step explanation:

(w-4/9)(-2/3)=-4/5

-2/3w+8/27=-4/5

-2/3w=-4/5-8/27

-2/3w=-108/135-40/135

-2/3w=-148/135

w=(-148/135)/(-2/3)

w=-148/135*-3/2,

w=74/45

Determine the intercepts of the line.<br> y = -2x – 21<br> c-intercept:<br> y-intercept:
DanielleElmas [232]

Answer:

x-intercept = -6

<h2>y-intercept = -21</h2>

Step-by-step explanation:

x - intercept is for y = 0

y - intercept is for x = 0.

We have y = -2x - 21.

Substitute:

x = 0 → y = -2(0) - 12 = 0 - 12 = -12

y = 0 → 0 = -2x - 12          <em>add 2x to both sides</em>

2x = -12         <em>divide both sides by 2</em>

x = -6

if mr sulivan drove 7hrs within 385 miles and then he drives 3 hrs in the distance of 165 miles is the amount of time of the two
ehidna [41]

the amount of time of the two trips is a proportional relationship

<h3>What is proportional relationship?</h3>

mathematical expressions are said to be proportional if there unit rate are equal. this means that the expressions will give similar results when similar values are substituted into the equation.

<u>solution:</u>

Driving 7 hrs within 385 miles represents a unit rate of 385 / 7 = 55 miles per hour or 55 mph

while 3 hrs in 165 miles represents a unit rate of 165 / 3 = 55 mph

since both situations gave similar speed in miles per hour they are said to have a proportional relationship.

A city's population is currently 500,000. If the population doubles every 65 years, what will the population be 130 years from n
kompoz [17]

Answer:

2,000,000

Step-by-step explanation:

Simple maths, really.

65 times 2 is 130, and the population is already 500,000 with no time passing. 65 years later, the population would be 1,000,000. 65 years after that, the population would double again, so the answer would be 2 million.

Hope this helped!

Applicants who wish to be admitted to a certain professional school in a large university are required to take a screening test
Elden [556K]

Answer:

Probability of eligible applicants who pass the exam is 0.665

probability of applicants who are ineligible but pass the exam 0.063

Step-by-step explanation:

Total percentage eligible applicants who pass the exam

\textrm {89\%  of 70\%}= \dfrac{89\times70}{100}=62.3\%

Total  ineligible applicants  who pass the exam

\textrm {14\%  of 30\%}= \dfrac{14\times30}{100}=4.2\%

All applicants who pass this exam 62.3% + 4.2% = 66.5%

Probability of applicants who pass the exam

\textrm{probability }= \dfrac{66.5}{100}=0.665

Out of 66.5% applicants who pass the exam , 4.2% applicants are ineligible

\textrm{so the probability is}\dfrac{4.2}{66.5}=0.063

Probability of applicants who pass the exam is 0.665

probability of applicants who are ineligible but pass the exam 0.063
