I need help on this please please?

Answer:g+d=152

g+2d=30

4g+2d=42

4g+2d-(2g+2d)=42-30

4g+2d-2g-2d =12 2g. =12

g=6

d+6=15

d=15-6

d=9

6 goats and 9 ducks

The number of animals are 6 goats and 9 ducks.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

Number of farmhouse shelters=15

Total number of legs=42

Now,

Part A:

Let's use g to represent the number of goats and d to represent the number of ducks in the farmhouse.

We know that there are 15 animals in total, so:

g + d = 15

We also know that goats have 4 legs and ducks have 2 legs, and there are a total of 42 legs:

4g + 2d = 42

Part B:

We can solve this system of equations algebraically by using substitution or elimination.

Substitution Method:

Solve for one variable in terms of the other in one equation, and substitute into the other equation.

Solve for the remaining variable.

From the first equation, we know that:

g = 15 - d

Substitute g = 15 - d into the second equation:

4g + 2d = 42

4(15 - d) + 2d = 42

60 - 4d + 2d = 42

-2d = -18

d = 9

So there are 9 ducks in the farmhouse.

To find the number of goats, substitute d = 9 into g = 15 - d:

g = 15 - 9

g = 6

Therefore, by the unitary method the answer will be 6 goats and 9 ducks

[tex]\Huge\boxed{C.68}[/tex]

Step-by-step explanation:

Hello There!

The exterior angle of a triangle rule is that the exterior angle  is equal to the sum of the interior opposite angles

So essentially what I'm saying is that

z = 29 + 39

29+39=68 therefore the measure of angle z is 68

Answer:

-972

Step-by-step explanation:

if f(1)= 4 and f(n) = -3f(n-1) then find the value of f(6)

If f(1)= 4

f(2) = -3f(2-1)

f(2) = -3f(1)

f(2) = -3(4)

f(2) = -12

f(3) = -3f(3-1)

f(3) = -3f(2)

f(3) = -3(-12)

f(3) = 36

f(4) = -3f(4-1)

f(4) = -3f(3)

f(4) = -3(36)

f(4) = -108

f(5) = -3f(5-1)

f(5) = -3f(4)

f(5) = -3(-108)

f(5) = 324

f(6) = -3f(6-1)

f(6) = -3f(5)

f(6) = -3(324)

f(6) = -972

hence the sixth term of the sequence is -972

Answer:

17.2 cm

Step-by-step explanation: Each side would be 19 cm since a triangle has three sides. Next, we will use pythagorean theory. Since the equation would be a^2 + b^2 = c^2. Since 19^2 is 361 and is getting subtracted by 64 (we get it because at the bottom, we have to split it. also, 8 squared is 64). Then we get 297, which the base root with one number behind the decimal would be 17.2 cm.

To find:

The value of the given expression when [tex]x=64[/tex] and [tex]y=27[/tex].

Solution:

We have,

[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]

Putting [tex]x=64[/tex] and [tex]y=27[/tex], we get

[tex]=((64)^2(27)-3)^0+(64)^{\frac{1}{3}}-(4(64))^{\frac{1}{2}}[/tex]

It can be written as

[tex]=((64)^2(27)-3)^0+(4^3)^{\frac{1}{3}}-(4)^{\frac{1}{2}}(64)^{\frac{1}{2}}[/tex]

[tex]=1+4-2(8)[/tex]           [tex][\because a^0=1,a\neq 0][/tex]

[tex]=5-16[/tex]

[tex]=-11[/tex]

Therefore, the value of the given expression [tex]-11[/tex] when [tex]x=64[/tex] and [tex]y=27[/tex].

sin trigonometry ratio

Step-by-step explanation:

Given

See attachment for triangles

Explain why [tex]\frac{a}{8} = \frac{x}{12}[/tex]

From the attached diagram, both triangles are similar triangles because

(1) the second triangle is a dilation of the first triangle by a ratio of 1.5

i.e

[tex]k = \frac{12}{8}[/tex]

[tex]k = 1.5[/tex]

(2) They have angle 30 degrees, and have their right angles located at the same point

In the first triangle, the sine of 30 degrees is represented as:

[tex]sin(30) = \frac{Opp}{Hyp}[/tex]

This gives:

[tex]sin(30) = \frac{a}{8}[/tex]

In the second triangle:

[tex]sin(30) = \frac{Opp}{Hyp}[/tex]

So:

[tex]sin(30) = \frac{x}{12}[/tex]

By comparison:

[tex]sin(30) = sin(3)[/tex]

Hence:

[tex]\frac{a}{8} = \frac{x}{12}[/tex]

Answer:

48.3

Step-by-step explanation:

→ See what side is not given

Opposite

→ Find a triangle with out an O in it

Cos = Adjacent / Hypotenuse

→ Make what you want to find the subject

Hypotenuse = Adjacent / Cos

→ Substitute the numbers into the formula

41 / cos (32) = 48.3

Answer:

Option D

Step-by-step explanation:

By applying Pythagoras theorem in triangle ABC,

(Hypotenuse)²= (Leg 1)² + (Leg 2)²

AC² = AB² + BC²

AC² = (40 - 15)² + (80 - 75)²

AC² = (25)² + 5²

AC² = 650

AC = √650

AC = 25.495 ft

Since, area of a rectangle = Length × Width

Therefore, area of the garden = 25.495 × 6

                                                  = 152.97

                                                  ≈ 153 ft²

Since, 150 is very close to 153, approximate area of the rectangular garden is 150 ft².

Option D is the answer.
