A farmhouse shelters 20 animals. Some are pigs and some are ducks. Altogether there are
46 legs. How many of each animal are there?

Part A

Answers:

-------------------------

Explanation:

The two terms are separated by a plus sign. Since we have two terms, we have a binomial.

The variables are p and q, acting as placeholders for unknown numbers.

The coefficients are the numbers to the left of the variables, which are the 4 and 7.

The degree of multivariable polynomials is found by adding up the exponents for each term, then picking the largest sum. In each case, we get a sum of 3 for each monomial. The degree of the entire polynomial is therefore 3.

==============================================

Part B

Answer:   t^3 - 20t + 26

-------------------------

Explanation:

We have an expression of the form

(6t^3-3t+5) - x = (5t^3 + 17t - 21)

which rearranges to

-x = (5t^3 + 17t - 21) - (6t^3-3t+5)

-x = 5t^3 + 17t - 21 - 6t^3 + 3t - 5

-x = (5t^3 - 6t^3) + (17t+3t) + (-21-5)

-x = -t^3 + 20t - 26

x = -(-t^3 + 20t - 26)

x = t^3 - 20t + 26

Answer:

[tex]2\sqrt{46}[/tex]

Step-by-step explanation:

The factor of the 184 will be 2 × 2 × 46. Then the expression is equivalent to the expression 2√46, Then the correct option is B.

The equivalent is the expression that are in different forms but are equal to the same value.

The given expression is √184.

Then the factor of the 184 will be

184 = 2 × 2 × 46

Then the square root of 184 will be

√184 = 2√46

Answer:

to find the mean you must add all of the numbers in a data set together and then divide by how many numbers there are.

Answer:

give brainliest?

Step-by-step explanation:

the mean or average of a data set is found by adding all numbers in the data  and then dividing by the number of values in the set.

For example, if you have 10 numbers, you add them up and divide by 10. This would give you the mean of the data.

Here's another example with the numbers: 9,8,22,7,7,8,17

First add the numbers up: 9+6+20+7+7+8+20+2+2 = 81 Then divide 81 by the total number of data points, 9, and you get 9.

Theerefore the mean is 9.

Answer:

Let brother's present age be x and sister's present be y

x=y+3

5 years ago

x-5/y-5=4/3

Putting the value of x

y+3–5/y-5=4/3

y-2/y-5=4/3

3(y-2)=4(y-5)

3y-6=4y-20

y=14

x=14+3=17

Brother's present age =17years, sister's present age=14years

We know that,

[tex]V = \frac{1}{3} (a{}^{2} + ab + b{}^{2})h \\ [/tex]

Also,

[tex]l {}^{2} = h {}^{2} + (b - a) {}^{2} [/tex]

[tex]6{}^{2} = h {}^{2} + (9 - 5) {}^{2} [/tex]

[tex]36 = h {}^{2} +16[/tex]

[tex]h {}^{2} = 36 - 16[/tex]

[tex]h = \sqrt{20} [/tex]

[tex]h = 4.47[/tex]

Now , putting the value in the formula of volume

we get,

[tex]V = \frac{1}{3} (5{}^{2}+ 5 \times 9 + 9{}^{2})4.47 \\ [/tex]

[tex]V = \frac{1}{3} (25 + 5 \times 9 + 81)4.47 \\ [/tex]

[tex]V = \frac{1}{3} (25 + 45 + 81)4.47 \\ [/tex]

[tex]V = \frac{1}{3} \times 151 \times 4.47 \\ [/tex]

[tex]V = 224.99[/tex]

Hence, the volume of the given frustum is 224.99 cubic unit

Answer:

ion kno gang ask a teacher

Select all expressions that are equal to 5/8.

Let's review each option one by one.

Option A

Thus, Option A is correct.

Option B

Thus, Option B is incorrect.

Option C

Thus, Option C is incorrect.

Option D

Thus, Option D is correct.

Option E

Thus, Option E is incorrect.

Answer: C. is not correct because angle 2 and angle 5 are same side interior angles. Same side interior angles of parallel lines always add up to 180 degrees. Therefore, the only way angle 2 would be equal to angle 5 would be if they were both 90 degrees, which the two angles are not always right angles.

d + c = 19

100d + 15c = 1390

we can simplify the second equation

20d + 3c = 278

now d + c = 19

c = 19 - d

3c = 57 - 3d

now plug into second equation

20d + 57 - 3d = 278

17d = 278 - 57

17d = 221

d = 221 / 17

d = 13

now we can plug this into the first equation

13 + c = 19

c = 19 - 13

c = 6

10x-3y=12

Step-by-step explanation:

In algebra, we always add alike terms. Meaning, when a set has numbers with the same variable, in this case it was x, we can add/substract/divide them to simplify the equations.

The multiples of 5 include 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80...

Given that its a straight line, so the sum of three angles is 180°

So possible angles:
