Answer:

.8

Step-by-step explanation:

4/5 multiplied by 2 is 8/10, which is equivalent to .8

After converting the number 4/5 into decimal, the number is 0.8.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

We have to given that;

Fraction = 4/5

So, Write an equivalent fraction as;

⇒ 4/5

Multiply by 2 in denominator and numerator;

⇒ 4×2 / 5×2

⇒ 8 / 10

⇒ 0.8

Answer:

[tex]\frac{8}{9}[/tex]

Step-by-step explanation:

using the image attached as reference

(-4,-1) - the -4 becomes x1, and the -1 becomes y1

(5,7)  - the 5 becomes x 2 and the 7 becomes y2

plug this information into the equation

      7-(-1)

m=----------      

      5-(-4)

solve

       8

m=----------    

        9

​so your slope would become 8/9

Answer:

215/3

Step-by-step explanation:

71 multiplied by 3 (denominator) + 2 (remainder) divided by 3

The improper fraction for the given mixed fraction is 215/2.

The given fraction is [tex]71\frac{2}{3}[/tex].

These are just improper fractions written as a sum of whole number and a proper fraction. (improper fraction has the upper value(also called numerator) bigger or equal to denominator(the bottom value) and proper fraction has numerator value is less than that of the denominator)

They are written and can be converted to fraction as: [tex]a\frac{b}{c} = \frac{(a\times c)+b}{c}[/tex]

Now, [tex]71\frac{2}{3}=\frac{71\times3+2}{3}[/tex]

= (213+2)/3

= 215/3

Therefore, the improper fraction for the given mixed fraction is 215/2.

#SPJ6

Answer:

67.7

Step-by-step explanation:

The long sides contribute a total of 30 , while the two half semi-circumferences contribute pi * 12 giving a total of:

67.699 which rounded to the nearest tenth is:

67.7

Answer:

Step-by-step explanation:

perimeter = semicircle (x2) + parallelogram side (x2)

                = 1/2 π 12 (x2) + 15 (x2)

               = 37.7 + 30

               = 67.7

Step-by-step explanation:

4x^3 + 7x^3 - 5x + 9x + 3 + 11 = 11x^3 + 4x + 14

Answer and Step-by-step explanation:

Solution:

Given:

A, B and C are sets.

We have to prove that:

(A − B) ∩ (C − B) = (A ∩ C) − B.

Use an element x,

Let x Є (A – B), by the definition of difference:

X Є A  and x ∉ B.

And

X Є A ∩ C and x ∉ B

X Є (A ∩ C) – B

Now let x Є C – B

By the definition of difference:

X Є C and x ∉ B

By definition of intersection: x Є C and x Є( A ∩ C)  

By definition of difference, using that x Є(A ∩ C) And x  ∉ B:

X Є ( A ∩ C) – B

We know that: x Є (A – B) ∩ ( C – B)

Is equivalent to x Є A – B  and x Є C – B

So, ( x Є A and x ∉ B)

And (x Є C and x  ∉  B)

From this we know that x Є (A ∩ C) – B.

Answer:

We conclude that 'None of the above' is the correct answer.                    

Step-by-step explanation:

Given the expression

[tex]7x^2\:-\:12x\:-\:4[/tex]

Breaking the expression into groups

[tex]7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)[/tex]

Factor out [tex]x[/tex] from [tex]7x^2\:+\:2x[/tex]

[tex]=x\left(7x+2\right)[/tex]

Factor out -2 from [tex]\left(-14x-4\right)[/tex]

[tex]=-2\left(7x+2\right)[/tex]

so the expression becomes

[tex]7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)[/tex]

                         [tex]=x\left(7x+2\right)-2\left(7x+2\right)[/tex]

Factor out the common term [tex]7x+2[/tex]

                         [tex]=\left(7x+2\right)\left(x-2\right)[/tex]

Therefore, from the given options, we conclude that 'None of the above' is the correct answer.

Algebra I

Step-by-step explanation:

Step 1: Define equation

y = -(x - 3)² + 8

Step 2: Rewrite

Answer:

The trigonometric values for cos are C = A/H, which means that to find cos(60), you need to divide the adjacent side by the hypotenuse, which in this case gives you 1/2, so that is the value of cos(60).
