what is this equation 6x-4y=18 and -x-6y=7

Answer: 60°

Step-by-step explanation:

triangles always equal 180°, in this case you’re looking at the entire triangle so

60°+35°+25° = 120

180-120 = 60°

the missing angle is 60°

-25*25=-625

96+-96==0

ans=1-625

=-624

Answer:

- 624

Step-by-step explanation:

96+(-96)+32/32 - 25*25

-> 0+32/32-(25)(25)

-> 32/32 - (25)(25)

-> 1-(25)(25)

-> 1- 625

-> -624

Answer:

reduction

Step-by-step explanation:

cause it is a smaller version

Answer:

its a reduction

Step-by-step explanation:

and because an enlargement scale factor is over 1 and a reduction scale factor is between 0 and 1 so the smaller trapezoid is a reduction because it isn't the original.

Step-by-step explanation:

The volume of a triangular prism shaped box is 2,400 cubic centimeters.

Base of the triangle = 16cm

Sides of the triangle = 17cm

Length of the box = 20cm

Triangular prism

A triangular prism is a three-sided prism made of a triangular base and a corresponding side.

A. To find the height of the base = 3 x the volume divided by the base area = 15cm.

B. The approximate amount of card board used to make the candy box:

Using the lateral prism as the sides will be:

Lateral area =  Perimeter of triangle X height of the prism

Lateral area =  (16 + 17 + 17) X 20

Lateral area =  50 X 20

Lateral area =  1,000 cm2

Therefore, the answer is 1000cm2.

Answer:

A pair of angles on the same side of the transversal, one of which is and interior angle and the other one is an exterior angles, but do not form a linear pair, is known as corresponding angles

Answer: 33r + 9s

Step-by-step explanation: First, we need to distribute

the 3 through both terms inside the set of parenthses.

Students will often multiply the 3 by the 3s but forget

to multiply the 3 by the 9r, beware of this mistake.

So we get 6r + 9s + 27r which simplifies to 33r + 9s.

The equivalent expression is 33r + 9s

The expression is given as:

6r + 3(3s + 9r)

Expand the expression

6r + 9s + 27r

Collect like terms

6r + 27r + 9s

Evaluate the like terms

33r + 9s

Hence, the equivalent expression is 33r + 9s

$5557.88

Step-by-step explanation:

Everything starts at 100% and since it depreciates you subtract 13.5 from 100 =86.5% now we want percentage as a decimal so we divide by 100=0.865 our multiplier

Now you have the original amount that you purchased for times by the multiplier to the power of number of years=10

23700 times 0.865 power of 10

Hi there!

The answer is →[tex]15 \sqrt{3}[/tex]←

(Check the attached image for the explanation)

Answer:  " [tex]3\sqrt{154}[/tex] " ;

           or, write as:  " 37.229 " .
__________

Step-by-step explanation:
The digits of "1386" ;

add up to:  " (1 + 3 + 8 + 6) " ;

                 = " (1 + 3) + 8 + 6 " ;

                 = " (4) + 8 + 6 ;

                 = " (4 + 8 + 6) " ;

                 = " (4 + 8) + 6) " ;

                 = " (12) + 6 "

                 =  "18 " ;  

"18" is divisible ("evenly") ; by both: "2" :  {" 18 ÷ 2 = 9 ".} ;
                                            and by:  "3" :  {" 18 ÷ 3 = 6 ".}

Note:  If a number is "evenly divisible by both: "2" and "3" ; then said number is divisible by "6" ;
_________

Other: If the sum of the digits of a number result in a number that is evenly divisible by "9" ; then said number is evenly divisible by "9" ;
_________
  The sum of the digits of "1386" is: "18" ;
and:  the sum of the digits of:  "18" ;  ⇒ " 1 + 8 = 9" .
  {and:  " 9 ÷ 9 = 1 ".}.
_________
Note: If  number that ends with the last 2 (two) digits; in consecutive order; in which, taken as a "separate number" , is evenly divisible by "4" ; then, the entire said number is evenly divisible by "4".
  Note:  The number given:  "1386 " ; ends with:  "86" ;
             and:  " 86 ÷ 4  = 21.5" ; so we know that:
     "1386" is not evenly divisible by "4".
_________
Note: If a number ends with the digit: "5" ; or "0" ; then the number is evenly divisible by: "5" .  The number:  "1386" ; does not meant either of these criteria.
_________

Note: If a number ends with the digit:  "0" ; then the number is evenly divisible by: "10" .  The number:  "1386" ; does not meant this criterion.

_________
Note:  If a number ends with the last 2 (two) digits; in consecutive order; in which, taken as a "separate number" , is evenly divisible by "7" ; then, the entire said number is evenly divisible by "7".
 Note: The number given:  "1386 " ; ends with:  "86" ;
             and:  " 86 ÷ 7  = 12[tex]\frac{2}{7}[/tex] " ; so we know that:
     "1386" is not evenly divisible by "7".
_________
Note: If a number ends with the last 2 (two) digits; in consecutive order; in which, taken as a "separate number" , is evenly divisible by "4" ; then, the entire said number is evenly divisible by "4".
  Note: The number given:  "1386 " ; ends with:  "86" ;
             and:  " 86 ÷ 4  = 21.5" ; so we know that:
     "1386" is not evenly divisible by "4".
_________

Note:  If a number ends with the last 3 (three) digits; in consecutive order; in which, taken as a "separate number" , is evenly divisible by "8" ; then, the entire said number is evenly divisible by "8".
  Note:  The number given: "1386" ; ends with: "386" ;
             and:  " 386 ÷ 8 = 28[tex]\frac{1}{4}[/tex] " ; so we know that:
      "1386" is not evenly divisible by "8" ;
_________
Since: we know that "1386"  is evenly divisible by "9" ;

and "9" is a perfect square;  

  {since: " 3² = 3 * 3 = 36 " ; and since:  " [tex]\sqrt[]{9} = 3[/tex] " }.

Let's see what the other factor of "1386" is when "9" is a factor:
  " 1386 ÷ 9 = 154 " ;  

_________
So:  √(154) ;

            =  √9  * √(154) ;

            =   3 *   √(154) ;

Let's look at the factors of 154:
_________
 ⇒   1 & 154;  2 and 77;

List this factors of "154" as:  1, 2, 77, 154;

    →  none of which are "perfect squares" ;

→  So, the answer is:  " [tex]3\sqrt{154}[/tex] " ;

     or: further calculate with a calculator:
         →   " [tex]3 * \sqrt{154} =[/tex][tex]37.2290209379725698[/tex] " ;

          →     round to:   " 37.229 ".

Answer:

30

Step-by-step explanation:

All straight line equations are in the form:

[tex]y=mx+c[/tex]

Where m is the gradient and c is the y-intercept

In this equation +30 is the y-intercept

Answer:

The y-intercept is 30 in this equation

Step-by-step explanation:

This equation is in slope-intercept form.

Slope intercept form includes two things, (you can probably already guess)

It includes the slope of the line and the y-intercept

In all slope-intercept form equations the 20x would be the slope and the 30 would be the y-intercept

Answer:

hii I am new can be friends

Step-by-step explanation:

Given that:

∛(2) * 2^(-1/13) * ¹²√(32)

= ∛(2) * 2^(-1/13) * ¹²√(2⁵)

[since, ⁿ√(a) = a^(1/n)]

= 2^(1/3) * 2^(-1/13) * 2^{5 * (1/12)}

= 2^(1/3) * 2^(-1/13) * 2^{(5*1)/12}

= 2^(1/3) * 2^(-1/13) * 2^(5/12)

[since, a^m * a^n = a^(m+n)]

= 2^{(1/3) - (1/13) + (5/12)}

Take the LCM of 3, 13 and 12 is 156.

= 2^[{(1*52) - (1*12) + (5*13)}/156]

= 2^{(52 - 12 + 65)/156}

= 2^{(117 - 12)/156}

= 2^(105/156)

Now reduce the power fraction in simplest form by cancelling method.

= {2^(35)}^(1/52) (or)

= ⁵²√{2^(35)}

Answer: Hence, the simplified form of ∛(2) * 2^(-1/13) * ¹²√(32) = ⁵²√{2^(³⁵)}.

Applying the law of indices to the roots, we have that

[tex]\sqrt[n]{x} = x^{\frac{1}{n} }[/tex]

So,

[tex]\sqrt[3]{2}[/tex] × [tex]2^{-\frac{1}{13} }[/tex] × [tex]\sqrt[12]{32}[/tex] = [tex]2^{\frac{1}{3} }[/tex] × [tex]2^{-\frac{1}{13} }[/tex] × [tex]32^{\frac{1}{12} }[/tex]

=  [tex]2^{\frac{1}{3} }[/tex] × [tex]2^{-\frac{1}{13} }[/tex] × [tex](2^{5} )^{\frac{1}{12} }[/tex]

= [tex]2^{\frac{1}{3} }[/tex] × [tex]2^{-\frac{1}{13} }[/tex] × [tex]2^{\frac{5}{12} }[/tex]

Since we have the same base in all three numbers, we have that from the law of indices, [tex]a^{x}[/tex] × [tex]a^{y}[/tex] = [tex]a^{x + y}[/tex]

= [tex]2^{\frac{1}{3} }[/tex] × [tex]2^{-\frac{1}{13} }[/tex] × [tex]2^{\frac{5}{12} }[/tex]

[tex]= 2^{\frac{1}{3} + (-\frac{1}{13}) + \frac{5}{12} } \\= 2^{\frac{1}{3} - \frac{1}{13} + \frac{5}{12} }[/tex]

Taking L..C.M of the denominators of the exponents, the L.C.M is 156.

So,

[tex]2^{\frac{1}{3} - \frac{1}{13} + \frac{5}{12} }\\= 2^{\frac{52 - 12 + 5 X 13}{156} } \\= 2^{\frac{52 - 12 + 65}{156} }\\= 2^{\frac{40 + 65}{156} }\\= 2^{\frac{105}{156} }[/tex]

Simplifying the exponent, we have

[tex]2^{\frac{105}{156} } \\= 2^{\frac{35}{52} }[/tex]

So, [tex]\sqrt[3]{2}[/tex] × [tex]2^{-\frac{1}{13} }[/tex] × [tex]\sqrt[12]{32}[/tex] = [tex]2^{\frac{35}{52} }[/tex]
