Answer:

SA = 384 in²

Step-by-step explanation:

Assuming we're finding surface area:

SA of top of large cube: 8(8) - 4(4) = 48 in²

SA of sides of large cube: 4(8)(8) = 256 in²

SA of exposed faces of small cube: 5(4)(4) = 80 in²

Total = 48 + 256 + 80 = 384 = ∑SA

Answer:

She has $125 in the register before selling any tickets.

Step-by-step explanation:

If the cost of each ticket is $80 then the equation would just be d=80n. However, by adding 125 without any coefficient, this would make our starting point 125 and not 0. Our starting point is how much money is in the register prior to selling anything.

Answer:

here's your solution

=> we need to solve this ( x^2 -y^2)

=> it is given that x = 12 y= 11

=> now putting the value of these in question

=>. 12^2 - 11^2

=> 144 - 121

=. 23

Answer:

k = -4

Step-by-step explanation:

Step 1: Subtract 1 from both sides

Step 2: Multiply both sides by 2

Step 3; Divide both sides by 5

[tex]\frac{5}{2}k+1=-9\\\\\frac{5}{2}k =-9-1\\\\\frac{5}{2}k = - 10\\\\5k = -10*2\\\\5k = -20\\\\k =\frac{-20}{5}\\\\k = -4[/tex]

Answer:

k= -4

Step-by-step explanation:

Solve for k by simplifying both sides of the equation, then isolating the variable.

Answer:

360.

Positive answer, as negatives divided by negatives are positives.

Answer:

negative 8.64 divided by negative 0.024 = 360

Step-by-step explanation:

a positive ÷ by a negative = a negative

a negative ÷ by a positive = a negative

a positive ÷ by a positive = a positive

Answer:

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm ihnc

Step-by-step explanation:

I can't see pictures, but I'm assuming you want it solved.

x+2>7.

Cancel out the 2 by subtracting 2 from both sides.

x+2>7

 -2   -2

x>5

So the inequality is x>5.

Answer:

48 and 5%; 40 and 8%

Step-by-step explanation:

The computation of the difference between the percentage increase for each town from 2016 to 2017 is given below:

Year Ogdenville North Haverbrook

2016              960                500

2017              1008               540

So here the difference would be

For 2016 to 2017

= 1008 - 960

= 48

The percentage increase is

= 48 ÷ 960

= 5%

And,

= 540 - 500

= 40

And, the percentage increase is

= 40 ÷ 500

= 8%

Answer:

8/4 = 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

every time x goes up 1,  y goes up 4  

x = 3  minus x = 2  is a delta (a change of 1)

x = 4  minus x = 3  is a delta (a change of 1)

x = 5  minus x = 4  is a delta (a change of 1)

       the delta x is ALWAYS 1 for this table you can always substract x's to find the delta     delta is symbolized by Δ      Δx  for the delta x

y = 7  minus y = 3  is a delta (a change of 4)

y = 11  minus y = 7  is a delta (a change of 4)

y = 15  minus y = 11  is a delta (a change of 4)

    the delta y is ALWAYS 4 for this table you can always substract y's to find the delta     delta is symbolized by Δ     Δy  for the delta y

the slope m = Δy / Δx      m = 4 / 1     m = 4

     y = mx + b             when x = 0    then  y = b   (called the y intercept)

so how do we find the y intercept?    

look at the pattern in the TABLE  Δx  and Δy

   when x = 1    y = (3 - 4)  = -1

             x = 0    y =( -1 - 4)   = -5

so       y = 4x - 5     is a line equation for the data in this table

                                I believe there are other forms for linear equations

                               I chose the y-intercept form

use the point slope equation

       (y - y1)  =  m(x - x1)            where (x1, y1)  are the coordinates of a point on  

                                                the line

       when you know the slope of the line and a point on the line

       as before

       m = (y2 - y1)  / (x2 - x1)          from the table

           = (7 - 3) / (3 - 2)                 still equals

           = 4/1  =  4        

        pick a point on the line    say x= 4 and y = 11    (4, 11)

       (y - y1)  =  m(x - x1)    

        y - 11   =   4(x - 4)              point slope form

         solving point slope form  for  y

        y  - 11  =   4x - 16               add 11 to both sides    

           y  =  4x - 5                    back to the y-intercept form

Answer:

B?

Step-by-step explanation:

Answer:

The answer is C.

[tex](3x + 2)(x - 4) = 0 \\ 3x + 2 = 0 \: \: \: \: and \: \: x - 4 = 0 \\ x = \frac{ - 2}{3} \: \: \: and \: \: \: \: x = 4[/tex]

Answer:

g(x)=2x-3÷5

g=-11 as give by question

Answer:

The larger circle has an approximate area of 314 cm²

Step-by-step explanation:

As you can see by the diagram, the white circle is twice as wide as the grey circles.  That means that its radius is also twice theirs.

The grey circles have a radius of 5cm, so the larger has a radius of 10cm.

The radius of a circle is equal to πr², where r is the radius of the circle.  So the larger circle's radius is:

π × 10²

≈ 3.14 × 100

= 314.

So the larger circle has an approximate area of 314 cm²

Answer:

D, 6500 increased by 1.4% is 6591 plus another 1.4% which is 6683 and for the last year you add another 1.4% to get the final answer which is D 6,776.84

Answer:

P- 6500

R-1.4%

T- 3yrs

I-?

I first find simple interest,

I=P×R×T÷100

=273

then you add your answer to the price(6500)

273+6500=6773

Answer:

The answer is C x=15

Step-by-step explanation:

Simplify both sides of the equation.

2(x−2)=26

(2)(x)+(2)(−2)=26(Distribute)

2x+−4=26

2x−4=26

Add 4 to both sides.

2x−4+4=26+4

2x=30

Divide both sides by 2.

2x /2  =  30/ 2

x=15

Answer:

MC= 11cm

BCM= 49.68°

Step-by-step explanation:

MC= 1/2 AC

1/2 AC = 11

MC= 11

∠α = arcsin(a/c)

= arcsin( 12.961481396816/17)  

=arcsin(0.76244008216563)

=0.86708 rad

= 49.68°
