Answer:

120+ 4(square root)15

120+15.49=135.49

135.49 is the perimeter

The perimeter of the triangle having two angles 60 degrees, 60 degrees, and one side [tex]4\sqrt{15}[/tex] is, [tex]12\sqrt{15}[/tex] or 46.47

Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.

Perimeter = Sum of length of the all the sides

Given that,

the triangle having two angles 60 degrees, 60 degrees,

and one side

It is known that, total sum of all the angles of triangle is 180°

A = 60°

B = 60°

C = ?

A + B + C = 180°

60° + 60° + C =  180°

C =60°

Hence, it is a equilateral triangle

And for equilateral triangle length of all sides are equal

a =  [tex]4\sqrt{15}[/tex]

b =  [tex]4\sqrt{15}[/tex]

c =   [tex]4\sqrt{15}[/tex]

Perimeter =  [tex]4\sqrt{15}[/tex] +  [tex]4\sqrt{15}[/tex] +  [tex]4\sqrt{15}[/tex]

Perimeter = 12√15

So, the perimeter is 12√15

Answer:

First of all, we can see that this shape have 4 90° angles.

Secondly, since x = 5 we have:

 3 × 5 -2 = 15 - 2 = 13 (cm)

And: 5 + 8 = 13 (cm)

=> The two adjacent sides that make up the angle is equal to each other

So this shape is a quare.

=> This shape is a square.

Step-by-step explanation:

Answer:

m∠ACB = 39°

m∠BCD = 81°

m∠ACE = 60°

Step-by-step explanation:

From the picture attached,

m∠ACD = 120°

Since, m∠ACD = m∠ACB + m∠BCD

x + (2x + 3) = 120°

3x + 3 = 120

3x = 117

x = 39

Therefore, m∠ACB = 39°

m∠BCD = (2x + 3) = 2(39) + 3

             = 81°

Since, m∠ACE +  m∠ACB + m∠BCD = 180° [Angles formed at a point on a straight line]

m∠ACE + 39 + 81 = 180

m∠ACE = 180 - 120

m∠ACE = 60°

Answer:

B. The square root of 34 is an irrational number.

Step-by-step explanation:

The square root of 34 is a rational number if 34 is a perfect square.

Since 34 is not a perfect square, it is an irrational number.

Since the square root of 34 is not a perfect square, hence, the square root of 34 is an irrational number: Option B is correct.

Irrational numbers are numbers that cannot be written as a ratio of two integers.

Since the square root of 34 is not a perfect square, hence, the square root of 34 is an irrational number.

Answer:

[tex]\huge\boxed{\text{18 boys}}[/tex]

Step-by-step explanation:

This is basically just a ratio. If the ratio between the amount of girls to the amount of boys is 8 to 6, then we can create a fraction (girls/boys)

[tex]\frac{8}{6}[/tex]

Using what we know about the second statement (24 girls) we can make a ratio like this (also assuming girls/boys)

[tex]\frac{24}{x}[/tex]

Since the ratios must be equal, we can set them equal to each other.

[tex]\frac{8}{6} = \frac{24}{x}[/tex]

We can cross multiply to find x.

[tex]24 \cdot 6 = 144\\\\144 \div 8 = 18[/tex]

So there are 18 boys.

Answer:

12

Step-by-step explanation:

Answer:

1. D) 17%

2. 200 miles

Step-by-step explanation:

For the first question we can turn the information into a fraction, with the total number of pieces of fruit in the bowl (12) as the denominator and the number of apples (2) as the numerator.

[tex]\frac{2}{12}[/tex]

Then, divide:

2/12 = 0.17 = 17%

For the second question, we set up a proportion. We know that 60 miles corresponds to 30% and the whole distance of the trip, x, corresponds to 100%

[tex]\frac{60}{x} = \frac{30}{100}[/tex]

Cross multiply and solve:

60 * 100 = 30x

6000 = 30x

200 = x

Answer:

Step-by-step explanation:

when you have a negative exponent, you are going to have a fraction. Example: 2^4 * 2^-4= 2^4 is 16 2^-4 is 1/16.

You get the 16 but because it was a negative exponent, the 16 goes on the bottom. 16 as a fraction is 16/1.

When you multiply 16/1 and 1/16. It comes up to 16/16 or 1.

Answer:

Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

Step-by-step explanation:

The distributive property for any binary operation Ф under * in the given set S where a, b, c ∈ S

The binary operation a * (b Ф c) = (a * b) Ф (a * c) .

The operation * distributes over the operation Ф.

Now, when factoring, suppose we have an expression ab + ac. To factor this, we have a(b + c).

To check that our answer is correct, since the expression has been factored, we then distribute the multiplication over the addition to check if the factorization is correct.

So, a(b + c) = ab + ac which is our initial expression.

So, to use the distributive property to check work when factoring, once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

The way to use the Distributive Property to check your work when factoring is;

Option D; Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

The distributive property in algebra is expressed as; a(b + c) = ab + ac

Now, to use the distributive property to check the work when factoring, we have to expand the factored form first.

For example, we have; 2(3 + 4)

From distributive property, we have;

(2 × 3) + (2 × 4) = 14

This should be the same with the original factored expression; 2(7) = 14

Thus, the method is Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

The instantaneous velocity at t = 1 will be:

Step-by-step explanation:

Given the position of an object at a time [tex]t[/tex]

[tex]s\left(t\right)=-8-9t[/tex]

As we know that determining the derivative of the position function with respect to time t would give us the instantaneous velocity, so

[tex]\frac{ds}{dt}=\frac{d}{dt}\left(-8-9t\right)[/tex]

Applying the sum/difference rule:

[tex]\left(f\pm g\right)'=f\:'\pm g'[/tex]

[tex]\frac{ds}{dt}=-\frac{d}{dt}\left(8\right)-\frac{d}{dt}\left(9t\right)[/tex]

as

[tex]\frac{d}{dt}\left(8\right)=0[/tex]    ∵ [tex]\frac{d}{dx}\left(a\right)=0[/tex]

and

[tex]\frac{d}{dt}\left(9t\right)=9[/tex]   ∵ [tex]\mathrm{Take\:the\:constant\:out}:\quad \left(a\cdot f\right)'=a\cdot f\:'[/tex]  and [tex]\frac{d}{dt}\left(t\right)=1[/tex]

so the expression becomes

[tex]\frac{ds}{dt}=-\frac{d}{dt}\left(8\right)-\frac{d}{dt}\left(9t\right)[/tex]

   [tex]=-0-9[/tex]

   [tex]=-9[/tex]

As the derivative is constant.
