Answer:

14

Step-by-step explanation:

3x-7=2x(isosceles triangle)

x=7

AC=3(7)-7=21-7=14

The length of the side AC in the given triangle is 14 units.

A polygon with three sides, angle and vertex is called a triangle.

Given is a triangle ABC, with sides, AB = 2x, AC = 3x-7 and BC = 4x-10,

We need to find the length of AC,

According to the figure, ∠B ≅ ∠C, therefore, according to the theorem of triangles, that sides opposite to congruent angles are congruent,

Therefore, AC = AB

2x = 3x-7

x = 7

AC = 3(7)-7

AC = 14

Hence, the length of the side AC in the given triangle is 14 units.

Answer:

1887.6 ft³

Step-by-step explanation:

What is the volume of a cylinder with a height of 6.8 ft and a base with a radius of 9.4 ft, to the nearest tenth of a cubic foot?

The formula for the volume of a cylinder is given as:

πr²h

From the above question,

r = 9.4 ft

h = 6.8 ft

The volume of the cylinder =

π × 9.4² × 6.8

= 1887.61966 ft³

Approximately = 1887.6 ft³

Step-by-step explanation:

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

Answer:

3^11

Step-by-step explanation:

You add the 6 and the 5 to make 11.

Now you can multiply 3 to the power of 11.

So 3×3×3×3×3×3×3×3×3×3×3

Which would equal 177147.

Answer:

[tex]3^{11}[/tex] or 177147 (Depending on how you are supposed to answer)

Step-by-step explanation:

The first rule for exponents is "Product of powers rule: Add powers together when multiplying like bases". "3" is the base in this situation for both of the two values. Hence, they are common between the two of them. Therefore, we can apply this rule to the problem. If we add the exponents we get [tex]3^{11}[/tex].

Answer:

The length is 8

The width is 8

Answer:

Step-by-step explanation:

this is about algebra, and my calculus prof. says that all people struggle with algebra, so work on it  :D

P = 32  ( the total )

use the formula

P = 2L + 2W

but we are told that L =3W also sooo put that into L

P = 2(3W ) + 2w

32 = 6W + 2W

32 = 8W

4 = W

so width is 4

and length is 12
