The farmer walks by the pen with the chickens and pigs. He counts 18 heads and 50 feet. How many of each, chicken and pigs, are there?

Answers

Answer 1

Answer:

chickens = 11

pigs = 7

Step-by-step explanation:

this would be solved using simultaneous equation

let c = chicken .

p = pigs

A normal pig and chicken both have 1 head. thus :

c + p = 18 equation 1

A normal pig has 4 legs and a normal chicken has 2 legs. Thus

2c + 4p = 50 equation 2

multiply equation 1 by 2

2c + 2p = 36 equation 3

subtract equation 3 from 2

2p = 14

p = 7

substitute for p in equation 1

c + 7 = 18

c = 11

Find the missing height of the parallelogram described. b = (x + 4) yd, (blank text) yd, (5x + 20) yd2

Answers

Answer:

5yards

Step-by-step explanation:

Area of the parallelogram = Base * Height

Given

Area = (5x+20)yd²

Base = (x+4)yd

Required

height

Substitute into the formula

5x+20 = x+4 * Height

Height = 5x+20/x+4

Height = 5(x+4)/x+4

X+4 cancels out to have;

Height = 5

Hence the height of the parallelogram is 5yards

The ratio of dogs to cats in the neighborhood was 3 to 7. If a total of 210 dogs and cats were in the neighborhood, how many cats were there? Complete the statement by providing the correct response in number form.

Answers

Answer:

147 cats

Step-by-step explanation

There are 3 dogs/ 7 cats

3x + 7x = 210

10x = 210

210 ÷ 10 = 21

Therefore,

x = 21.

dogs would be 3x (3 x 21) = 63

cats would be 7x (7 x 21) = 147

Math honestly shouldn't exist-

Answers

Answer:

This isn't really that hard... ∠A = 166°

Step-by-step explanation:

Because ∠A and ∠B are corresponding angles of a set of parallel lines, that means they are equal, so you can use this equation to solve for x:[tex]7x+40=3x+112[/tex] ⇒ [tex]4x=72[/tex] ⇒ [tex]x=18[/tex]. To find ∠A, just substitute x for 18 and you'll get that ∠A equals 7 * 18 + 40 = 126 + 40 = 166°.

Milo drinks 2/5 of a bowls of water in 1/3 of an hour. How many hours will it take Milo to drink an entire bowl of water?

Answers

Answer:

It would take Milo 5/6 of an hour to drink an entire bowl of water.

Step-by-step explanation:

In this case, you can use a rule of three to find how many hours it will take to drink 1 bowl of water given that 2/5 of a bowl of water takes 1/3 of an hour:

2/5 of a bowl → 1/3 of an hour

1 bowl → x

x=(1*1/3)÷2/5

x=1/3÷2/5

x=(1*5)/(3*2)

x=5/6

According to this, the answer is that it would take Milo 5/6 of an hour to drink an entire bowl of water.

The floor of a storage unit in the shape
of a rectangular prism has an area of 106 1/4 square feet. The height of the storage unit is 7 1/2 feet. What is the volume of the storage unit?
A. 742 1/8ft B. 744 1/4 ft C. 795 1/4 ft D. 796 7/8 ft

Answers

Answer:

V = 796 7/8 ft^3

Step-by-step explanation:

The storage unit has a rectangular shape.

Thus, the volume is V = (area of floor)(height)

V = (106 1/4 ft^2)(7 1/2 ft)

V = 796 7/8 ft^3

Converting 106 1/4 ft to 106.25 makes it easier to use a calculator here. Same with 7 1/2 ft: 7.5 ft

QUESTION 10 of 10: You pay $1,000 for your insurance policy that covers up to $1 million in losses. If the insurance company just broke even
on similar policies, which of the following is closest to the odds the insurance company assumes for your making a claim of $1 million?
оооо
O a) 1 in 2
Ob) 1 in 5
c) 1 in 50
d) 1 in 1,000

Answers

Answer:

It's D - 1 in 1,000

Step-by-step explanation:

If the company breaks even, it collects $1,000,000 and pays out $1,000,000. If it collects $1,000 from each company, that means it sold $1,000,000 / $1,000 = 1,000 policies, and it paid out on one of them. This means the expected odds are 1 in 1,000.

The one which is closest to the odds the insurance company assumes for your claiming $1 million is 1 in 1000. Hence, option D is correct.

What are arithmetic operations?

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given data in the question,

If the business is profitable, it will receive $1,000,000 and spend $1,000,000.

If it receives $1,000 from each business, it has sold,

$1,000,000 / $1,000 = 1,000 policies, and one of them saw a payout.

This indicates that the likelihood is 1 in 1,000.
