A population of 430 animals increases at an annual rate of 19%. Find the number of animals present after 5 years. Round your answer to the nearest whole number.

Answers

19% of 430 is 81.7.

81.7 x 5 = 408.5

408.5 + 430 = 838.5

The population of animals present after 5 years is 838.5, but rounded to the nearest whole number would make it 839.

Answer:

1026

Step-by-step explanation:

Initial number = 430Increase rate = 19% = 1.19 times per year

Number of animals after 5 years:

430*1.19^5 = 1026

Ms. Wang and her class are selling bags of cookies to raise money for a field trip.
Each bag weighs 140 grams and has 6 cookies.
Each cookie has the same amount of dough that weighs 14 grams.
Each cookie has the same amount of candy
If a bag of candy has 20 grams of Candy, how many bags of candy does the class need to make 18 cookies?

Answers

Answer:

9 bags of candy

Step-by-step explanation:

6 cookies at 14 grams each = 84 grams meaning the remaining grams of the 140 have to be the weight of the candy which = 56 grams (140-84). To find out how much candy is in one cookie divide 56 by 6 which = 9.33333. You then divide 20 by 9.3333 which = 2.14 (rounded to nearest 10th). Since you can get just over 2 cookies worth of candy per bag you only need half the number of cookies in bags of candy (9 bags)

help please! find m∠bcf

Answers

Answer:

BCF = 140°

See attached image.

Answer:

m<BCF=140°

Step-by-step explanation:

first find m<BCD

m<BCD=180-50-90

m<BCD=40°.

to find m<BCF, we can do 180-m<BCD, since m<BCD and m<BCF add up to 180° (they form a straight angle)

180-m<BCD=m<BCF

180-40=m<BCF

m<BCF=140°

Val needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 42m-by-42m square. Val says the area is 1005.48 m^2. Find the area enclosed by the figure. Use 3.14 for pi. What error might Val have made?

Thanks in advance!
I don't have anymore points so please make a good and accurate answer.

Answers

Answer:
Area of the enclosed figure = 3148.74 [tex]m^{2}[/tex]
Step-by-step explanation:
Area enclosed by the figure = 2 x area of the semicircle + area of the square
For the semicircle,
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{42}{2}[/tex]
= 21 m
area of a semicircle = [tex]\frac{1}{2}[/tex] x [tex]\pi r^{2}[/tex]
= [tex]\frac{1}{2}[/tex] x 3.14 x [tex](21)^{2}[/tex]
= 692.37 [tex]m^{2}[/tex]
area of a square = length x length
= 42 x 42
= 1764 [tex]m^{2}[/tex]
Thus,
area enclosed by the figure = 2 x 692.37 + 1764
= 3148.74 [tex]m^{2}[/tex]
The total area enclosed bu the figure is 3148.74 [tex]m^{2}[/tex]
