Answer:

8 pigs

Step-by-step explanation:

Since every animal has only 1 head, a total of 26 heads suggests that there are 26 animals in total.

Suppose all animals are chickens.

Total no. of feet = 26 chickens × 2 feet

                           = 52 feet

Difference in total no. of feet = 68 feet - 52 feet

                                                = 16 feet

Difference in no. of feet each animal has

= 4 feet (a pig) - 2 feet (a chicken)

= 2 feet

∴ No. of pigs = 16 feet ÷ 2 feet

                      = 8 pigs

Answer:

2

Step-by-step explanation:

1+1=2

Answer:

See below.

Step-by-step explanation:

1) 3 congruent sides and 3 congruent angles: equilateral, equiangular, acute

2) 2 congruent sides and a right angle: right isosceles

3) 2 congruent sides and an obtuse angle: obtuse isosceles

4) 1 obtuse angle and all different lengths of sides: obtuse scalene

5) 1 right angle and all different side lengths: right scalene

6) 2 congruent sides, all acute angles: acute isosceles

7) x + 2 = 10

x = 8

8) 10x + 3 + 10x + 3 + 34 = 180

20x + 40 = 180

20x = 140

x = 7

Notice that in the number 7952, the column of the "thousands" is that occupied by the number 7.

I order to round it to the thousands', we need to write ONLY a representing number in that column and zeros in the other following three columns.

Notice as well that the number 7 is followed bi a number 9 in the column of the hundreds. then we round the 7 to the following integer (8), and write:

7952 rounded to the nearest thousand is 8000

Answer:

The balance of the account is $64,190.

Step-by-step explanation:

The amount of money after t years of continous compounding is given by the following equation:

\(P(t) = P(0)e^{rt}\)

In which P(0) is the initial deposit and r is the interest rate, as a decimal.

$60,000 deposited for 6 years at 1.125% interest compounded continuously.

This means that \(P = 60000, r = 0.01125, t = 6\)

So

\(P(6) = 60000e^{0.01125*6} = 64190\)

The balance of the account is $64,190.

The amount of each payment to 2 decimal places = $90406.80

Explanation:

t = 18 year

Principal = P = $18,000

r = 9% 0.09

Using compound interest formula:

n = number of times it was compounded in a year.

since it is monthly, n = 12

The amount of each payment to 2 decimal places = $90406.80

Answer: Break the numbers you're multiplying into parts.

Step-by-step explanation:

What I find helps is splitting up the numbers and later adding them back together. An example of this is:

29×14

First I'd do 29×10, and get 290

Then 20×4, followed by 9×4, resulting in 80 and 36 respectively

Finally, 290+80+36= 406

I find the simplest numbers in the problem (2,5,10,20, etc.) and multiply from there. This may not be the best trick, but this is what I find helps. I hope this may help you too, and I wish you the best of luck.

Answer:

(-1)(11)(3)(5)

Step-by-step explanation:

First off:  -165 separates into the factors (-1) and (165).  Next, we divide 165 by 15, obtaining 15(11).

So far, we have (-1)(11)(15).

15 is still factorable.  We get:

(-1)(11)(3)(5), which is the desired prime factorization of -165.

Answer: A: It will cost $936.00 to carpet the floor.

B: It will cost $297.00 to wallpaper all four walls.

C: It will cost $33.25 to paint the ceiling.

D: The cost of the entire project will be $1266.25.

Step-by-step explanation:

To calculate the costs for carpeting, wallpapering, painting, and the overall cost of the project, we need to determine the areas that need to be covered and the corresponding prices for each material.

Given dimensions:

Room length: 26 feet

Room width: 18 feet

Room height: 9 feet

Door dimensions:

Height: 6 feet 6 inches

Width: 4 feet

Window dimensions (each):

Width: 2 feet

Height: 2 feet 6 inches

A: Carpeting the floor:

To find the area of the floor, we multiply the length and width of the room:

Floor area = Length × Width = 26 feet × 18 feet = 468 square feet.

To convert to square yards (since the carpet is sold per square yard), we divide by 9:

Floor area in square yards = 468 square feet / 9 = 52 square yards.

Cost to carpet the floor = Floor area in square yards × Cost per square yard = 52 square yards × $18.00 = $936.00.

B: Wallpapering the walls:

To find the area of the walls, we calculate the perimeter of the room (2 × (Length + Width)) and multiply it by the height of the room:

Wall area = Perimeter × Height = 2 × (26 feet + 18 feet) × 9 feet = 396 square feet.

Cost to wallpaper the walls = Wall area × Cost per square foot = 396 square feet × $0.75 = $297.00.

C: Painting the ceiling:

To find the area of the ceiling, we multiply the length and width of the room:

Ceiling area = Length × Width = 26 feet × 18 feet = 468 square feet.

Since a quart of paint covers 88 square feet, we need to determine the number of quarts required:

Number of quarts = Ceiling area / Coverage per quart = 468 square feet / 88 square feet = 5.32 quarts.

Since a gallon contains 4 quarts, the number of gallons required is 5.32 quarts / 4 quarts = 1.33 gallons.

Cost to paint the ceiling = Number of gallons × Cost per gallon = 1.33 gallons × $25.00 = $33.25.

D: Cost of the entire project:

Total cost = Cost to carpet the floor + Cost to wallpaper the walls + Cost to paint the ceiling

= $936.00 + $297.00 + $33.25 = $1266.25.

Therefore:

A: It will cost $936.00 to carpet the floor.

B: It will cost $297.00 to wallpaper all four walls.

C: It will cost $33.25 to paint the ceiling.

D: The cost of the entire project will be $1266.25.

Step-by-step explanation:

Bar and circle graphs compare things, or categories, while the rest involve numbers.

Arithmetic sequence and Geometric sequence a₁ is an integer, the numerator must be divisible by -21.

Let's denote the common difference of the arithmetic sequence as 'd' and the common ratio of the geometric sequence as 'r'.

Since a4, a7, and a12 form a geometric sequence, we can express the terms as follows:

a4 = a₁ + 3d

a7 = a₁ + 6d

a12 = a₁ + 11d

We know that a7 = 30, so we can substitute it into the equation:

a₁ + 6d = 30

Now, let's examine the ratio between consecutive terms in the geometric sequence:

(a7 / a4) = (a12 / a7)

Substituting the expressions for the terms, we get:

[(a₁ + 6d) / (a₁ + 3d)] = [(a₁ + 11d) / (a₁ + 6d)]

Cross-multiplying, we have:

(a₁ + 6d)(a₁ + 6d) = (a₁ + 3d)(a₁ + 11d)

Expanding the equation, we get:

a₁² + 12ad + 36d² = a₁² + 14ad + 33d²

Simplifying and rearranging terms, we obtain:

2ad = -3d²

Since the sequence is non-constant, the common difference 'd' cannot be zero. Therefore, we can divide both sides of the equation by 'd':

2a = -3d

Substituting the value of 'd' from the equation a₁ + 6d = 30, we have:

2a = -3(a₁ + 6d)

Expanding and simplifying:

2a = -3a₁ - 18d

Now, we can substitute the value of 'd' from the equation a₁ + 6d = 30:

2a = -3a₁ - 18(a₁ + 6d)

Expanding and simplifying further:

2a = -3a₁ - 18a₁ - 108d

Since a₁ + 6d = 30, we can substitute it again:

2a = -3a₁ - 18a₁ - 108(a₁ + 6d)

Expanding and simplifying:

2a = -3a₁ - 18a₁ - 108a₁ - 648d

Combining like terms:

2a = -129a₁ - 648d

Now, we can substitute the known value of a₇ = 30 into the equation a₁ + 6d = 30:

a₁ + 6d = 30

Rearranging the equation:

a₁ = 30 - 6d

Substituting this into the previous equation:

2a = -129(30 - 6d) - 648d

Expanding and simplifying:

2a = -3870 + 774d - 648d

Combining like terms:

2a = -3870 + 126d

Now, we can substitute the value of 2a = -3a₁ - 18a₁ - 108d into the equation:

-3a₁ - 18a₁ - 108d = -3870 + 126d

Expanding and simplifying:

-21a₁ - 108d = -3870 + 126d

Rearranging the equation:

-21a₁ = 234d - 3870

Dividing both sides by -21:

a₁ = (234d - 3870) / -21

Since arithmetic sequence and geometric sequence a₁ is an integer, the numerator must be divisible by -21

Solving a system of equations we can see that:

We can use the variables:

x = mass of the 60% solution.

y = mass of the 85% solution.

We can write a system of equations.

x + y = 70

x*0.6 + y*0.85 = 70*0.8

We can isolate x on the first equation to get:

x = 70 - y

Replace that in the other one:

(70 - y)*0.6 + y*0.85 = 70*0.8

Now we can solve this for y.

y*0.25 = 70*0.8 - 70*0.6

y = 14/0.25 = 56

Then he needs to use 56 ounces of the 85% solution, and 14 ounces of the 60% solution.
