Find a value c in the interval [0,3] such that f(c) is equal to the average value.

Answers

Answer:

1.5

Step-by-step explanation:

Numbers in the interval are 0, 1, 2 and 3

Average Value = (0+1+2+3)/4=1.5

The average value of the numbers in the interval {0,3} is 1.5.

What is an average?

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.

Mean is defined as the ratio of the sum of the number of data sets to the total number of data.

Given that the value c is in the interval [0,3]. The interval is written {0,1,2,3}.

The average of the numbers is calculated as,

Average Value = (0+1+2+3)/4

Average Value =1.5

Therefore, the average value of the numbers in the interval {0,3} is 1.5

1. The diameter of each tire on a model car is 10.668 mm. The actual diameter of a car's tire is 5.29 X 102 mm. About how many times larger is the actual diameter of a car tire than the diameter of the tire on the model car? A 5 times B 50 times +90 100 times D 500 times​

Answers

The number of times the actual diameter is larger than the model is 50 times.

A tire has the shape of a circle. The diameter is line that goes through the center of a circle and divides the circle into two.

In order to determine how many times larger the actual diameter is greater than the model, the actual diameter would be divided by the diameter of the model.

5.29 x 10² ÷ 10.668

529 ÷ 10.668

= 49.6

= 50 times

In a group of dogs and their owners, there are exactly 20 heads and 64 legs. How many dogs are in the group

Answers

Answer:

If we assume that everyone in the group is an owner, we would have

[tex]20*2=40[/tex] legs.

[tex]64-40=24[/tex] legs

Therefore, we need 24 more legs.

These 24 additional legs can be made from the difference of legs between the owners and dogs.

In this case, dogs have [tex]4-2=2[/tex] more legs than an owner.

24 ÷ 2 = 12.

There are 12 dogs in the group.

A high school drama club is selling tickets for the spring production. One day the president sold 12 adult tickets and 5 child tickets for a total of $169. The next day the president sold 22 adult tickets and 10 child tickets for a total of $314. Let a represent the cost of one adult ticket. Let c represent the cost of one child ticket. Which system of equations will solve for a and c? 12 a 5 c = 314. 22 a 10 c = 169. 12 a 5 c = 169. 22 a 10 c = 314. 5 a 12 c = 314. 22 a 10 c = 169. 22 a 5 c = 169. 12 a 10 c = 314.

Answers

Answer:

12a + 5c = 169

22a + 10c = 314

Step-by-step explanation:

if a = adult tickets and c = children's tickets

12 adult tickets and 5 children's tickets costs 169 dollars

12a + 5c = 169

Also, 22 adult tickets and 10 children's tickets cost 314 dollars

22a + 10c = 314

Two pillars of height 8 ft each with four faces of the gate of a stadium have one-one pyramid of height 4 ft each having same base on their tops. The base of each pillar is 6 ft × 6 ft. If the pillars with pyramid are painted at rate of Rs 89 per sq.ft , what will be the total cost? [ Please include figure too]

Help!! ~Thanks in advance! :)​

Answers

Answer:

₹ 44856

Step-by-step explanation:

There are 2 pillars, two right prisms of dimensions 6x6x8 ft, two right pyramids of dimensions 6x6x4 ft on top of prisms.

There will be 4 faces of each painted.

Area of each prism face:

6*8 = 48 ft²

Total area of prism faces:

8*48 = 384 ft²

Slant height of pyramid faces:

s = √h²+(a/2)², where h- height of pyramid, a - side of bases = √4²+(6/2)²= √16+9 = √25 = 5 ft

Area of each face of pyramid:

A = (1/2)*6*5 = 15 ft²

Total area of pyramid faces:

8*15 = 120 ft²

Total area to be painted:

384 + 120 = 504 ft²

Cost of paint:

504*89 = 44856

Calculate:
a) the total amount of tax Beatrice pays,

b)the total amount of tax as a percentage of the $40 000.

10b) Beatrice pays a yearly rent of $10 800.
After she has paid her tax, rent and bills, she has $12 000.
Calculate how much Beatrice spends on bills.

Answers

Answer:

  a) $6000 tax

  b) 15%

  c) $11,200 for bills

Step-by-step explanation:

a)

Beatrice pays 10% on the second $10,000 of her income, which is ...

  0.10×$10,000 = $1000

and she pays 25% on the amount over $20,000, which tax is ...

  0.25×($40,000 -20,000) = $5000

The total amount of tax Beatrice pays on her $40,000 income is ...

  $1000 +5000 = $6000 . . . . tax on $40,000

__

b)

The tax as a percentage of $40,000 is ...

  $6,000/$40,000 × 100% = 15% . . . . percentage of income paid in tax

__

c)

The amount left after tax, rent, and bills is ...

  $40,000 -tax -rent -bills = $12,000

  bills = $28,000 -tax -rent

  bills = $28,000 -6,000 -10,800 = $11,200

Beatrice spends $11,200 on bills.

The volume of a cone is (1/3)πr2h.

In this problem r=2h or h=(1/2)r

Hence V = (1/6)πr3

dV/dt = (1/2)πr2 dr/dt
