Answer:

$5740

Step-by-step explanation:

get 2.5% of 5600

5600/x=100/2.5

(5600/x)*x=(100/2.5)*x

5600=40*x

5600/40=x

140=x

x=140 <----- 2.5% of 5600

5600 + 140 = $5740

17. El precio de los terrenos en Lima es proporcional al área e inversamente proporcional a su distancia con respecto al centro

grin007 [14]

Answer:

375000

Step-by-step explanation:

We have that in this case the following proportion would be fulfilled:

Price * Distance / area

Now, we have that for a distance of 45 km and an area of 900 m ^ 2 the price is 250,000, now for a distance of 40 km but with an area of 1,200 m ^ 2, how would the price be, we replace:

250000 * 45/900 = P * 40/1200

12500 * 1200/40 = P

P = 375000

Which means that for these conditions the price is 375000.

3 in the power of ten word form

Ludmilka [50]

3 in the power of ten means "10^3."

$10^3$

How to solve exponents is to multiply the number as many times as it's exponent. So in this case you will have to multiply ten, three times.

$10\times10\times10=1000$

Which would mean that....

$10^3=1000$

The answer is 10^3.

Hope this helps.

Dr. Hawk works in an allergy clinic, and his patients have the following allergies: 71 are allergic to dairy products, 98 are al

sweet [91]

Answer: a) 65.75% and b) 13.7%

Step-by-step explanation:

Since we have given that

Number of people who are allergic to dairy products = n(A) = 71

Number of people who are allergic to pollen = n(B) = 98

Number of people who are allergic to animal dander = n(C) = 96

Number of people who are allergic to all n(A∩B∩C) = 33

Number of people who are allergic only to pollen = 30

Number of people who are allergic only to dairy product = 10

Number of people who allergic to dairy products and pollen n(A∩B)= 43

Now, we first find a, c, d, e from the Venn Diagram:

Since n(A∩B)= 43

$a+b=43\\\\a+33=43\\\\a=43-33\\\\a=10$

For Diary product,

$10+a+b+c=71\\\\a+b+c=61\\\\10+33+c=61\\\\c=18$

For pollen,

$a+30+b+e=98\\\\10+30+33+e=98\\\\e=98-73=25$

For animal dander,

$c+b+d+e=96\\\\18+33+25+d=96\\\\d=96-76=20$

So, Total allergic persons = 10+18+20+25+30+10+33=146

So, (a) What percent of Dr. Hawk's patients are allergic to animal dander?

Percentage that patients are allergic to animal dander is given by

$\dfrac{96}{146}\times 100=65.75\%$

(b) What percent of Dr. Hawk's patients are allergic only to animal dander?

Percentage that patients are allergic to only animal dander is given by

$\dfrac{20}{146}\times =13.7\%$

Hence, a) 65.75%

b) 13.7%
