If 4/5 of the population of a certain town is

kkurt [141]3 years ago
8 0

Hi! I'm happy to help!

Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)

2,000×4

8,000

8,000/5

Fractions are just a different way of putting division, so we can change this to a division problem:

8,000÷5=

1,600

1,600 of the people are middle class.

I hope this was helpful, keep learning! :D

The rabbit population in an isolated forest rises and falls depending on the population of predators. Within the year 2014201420
WITCHER [35]

Answer:

Step-by-step explanation:

If within the year 2014, the population p of the rabbits m months after January 2014 is modeled by the equation p = 0.05(m-1.5)(m-8.5) and the population reach 10,000 some time in February, to determine the time, given as months after January 1 2014, that the rabbit population reach ten thousand, we will substitute p = 10 into the modeled equation and get the value of m as shown;

p = 0.05(m-1.5)(m-8.5)+10 \\substitute \ p = 10\\\\ 10 = 0.05(m-1.5)(m-8.5)+10\\\\10-10 =  0.05(m-1.5)(m-8.5)\\\\0 =  0.05(m-1.5)(m-8.5)\\\\0/0.05 =  (m-1.5)(m-8.5)\\\\0 =  (m-1.5)(m-8.5)\\ (m-1.5)(m-8.5) = 0\\ m-1.5 = 0 \ and \ m-8.5 = 0\\m = 1.5 \ and \ 8.5\\

Hence the population of the rabbit reach 10,000 after 1.5 months and 8.5 months

The area of trapezoid TRAP is 100. Furthermore, TR = 32, AP = 8, and TP = RA. If AngleT = AngleR, what is the length of segment
Elenna [48]

Answer:

TP: 13

Step-by-step explanation:

A=((b1+b2)/2)*h

100=((8+32)/2)*h

100=(40/2)*h

100=20h

h=5

A=8*5+((32-8)/2)*0.5*5*2

100=40+(24/2)*5

60=12*5

thus, point E is is 12 away from T

Triangle TPE:

the catets are TE:12 and PE:5

Lets use the Pythagorean theorem:

a^2+b^2=c^2

12^2+5^2=c^2

144+25=c^2

169=c^2

c=(+/-)13

since distance can only be positive, the answer is:

segment TP has the length of 13 units

Solve for a<br>How do you solve this​
8_murik_8 [283]

Answer:

2.2

Step-by-step explanation:

To find a, you use a formula called the law of cosines:

The law of cosines tells us:

a^2 = b^2 + c^2 - 2bc cosA

So lets plug in the values:

a^2 =  4^2 + 3^2 -2(4)(3)cos(32)

a^2 = 25-24cos32

a^2 is roughly equal to 4.97

therefore a roughly equal to 2.2
