Step-by-step explanation:

$49 * (1-.2) = $39.20

Answer:

4×sqrt(5) inches

Step-by-step explanation:

Pythagorean theorem states that (for right triangles) if you square each shorter side and add those together, you will get the sum of the longest side (hypotenuse) squared.

This is commonly written as:

a^2 + b^2 = c^2, where c is the hypotenuse.

((For right triangles this will always be opposite the 90° angle.))

Since you know one of the shorter sides and the hypotenuse, rewrite the equation as such:

c^2 - b^2 = a^2, where a is the unknown length

This goes to:

sqrt(c^2 - b^2) = a

sqrt((12in)^2 - (8in)^2) = a

sqrt(144sqin - 64sqin) = sqrt(80sqin) = a

This simplifies to:

sqrt(16sqin)×sqrt(5sqin) = 4in×sqrt(5sqin) = a

what is 4/2/3 x 1/3/7 ?

[tex]6\frac{2}{21}[/tex]

Step-by-step explanation:

Rewriting our equation with parts separated

[tex]4 +\frac{2}{3} + 1 +\frac{3}{7}[/tex]

Solving the whole number parts

[tex]4 + 1 =5[/tex]

Solving the fraction parts

[tex]\frac{2}{3}+\frac{3}{7} =?[/tex]

Find the LCD of 2/3 and 3/7 and rewrite to solve with the equivalent fractions.

LCD = 21

[tex]\frac{14}{21} +\frac{9}{21} =\frac{23}{21}[/tex]

Simplifying the fraction part, 23/21,

[tex]\frac{23}{21} =1\frac{2}{21}[/tex]

Combining the whole and fraction parts

[tex]5 + 1+ \frac{2}{21} =6\frac{2}{21}[/tex]

Hence, The answer is [tex]6\frac{2}{21}[/tex]

Answer:

[tex]\sf 42893+2432743[/tex]

[tex]\sf =2475636[/tex]

Answer:

[tex]x=36[/tex]

Step-by-step explanation:

Solve for [tex]x[/tex] by simplifying both sides of the equation, then isolating the variable.

Therefore, [tex]x = 36[/tex].

To check your answer, apply 36 to where [tex]x[/tex] is.

[tex]33=\frac{36}{2} +15[/tex]

⇒ [tex]33=18+15[/tex]

[tex]18+15=33[/tex]    ☑

Answer:

[tex]\boxed{\sf x=36}[/tex]

Step-by-step explanation:

[tex]\sf 33=\cfrac{x}{2}+15[/tex]

[tex]\boxed {\sf Multiply\: both \:sides \:by \:2}[/tex]

[tex]\sf 66=x+30[/tex]

Swap sides so that all the variable terms are on the left hand side:

[tex]\sf x+30=66[/tex]

[tex]\boxed{\sf Subtract \:30\: from \:both \:sides}[/tex]

[tex]\sf x=66-30[/tex]

[tex]\boxed{\sf Subtract \: 30\: from \:66}[/tex]

[tex]\sf x=36[/tex]

Rates of change are the change of a quantity over another.

The rate of change of the mass position at 2.1 seconds is -89.6 cm/ s

The given parameters are:

[tex]\mathbf{A = |5|}[/tex] -- the amplitude

[tex]\mathbf{T = \frac 13}[/tex] --- the period

The position of the mass is modeled by:

[tex]\mathbf{y= Acos(wt)}[/tex]

Where:

[tex]\mathbf{w = \frac{2\pi }{T}}[/tex]

So, we have:

[tex]\mathbf{w = \frac{2\pi}{1/3}}[/tex]

[tex]\mathbf{w = 6\pi }[/tex]

[tex]\mathbf{y= Acos(wt)}[/tex] becomes

[tex]\mathbf{y = |5|cos(6\pi t)}[/tex]

[tex]\mathbf{y = 5cos(6\pi t)}[/tex]

Differentiate

[tex]\mathbf{y' = 5 \times -sin(6\pi t) \times (6\pi)}[/tex]

[tex]\mathbf{y' = -30\pi sin(6\pi t) }[/tex]

When t = 2.1, we have:

[tex]\mathbf{y' = -30\pi sin(6\pi \times 2.1) }[/tex]

[tex]\mathbf{y' = -30\pi sin(12.6\pi) }[/tex]

[tex]\mathbf{y' = -30\pi \times 0.9510}[/tex]

[tex]\mathbf{y' = -89.6296}[/tex]

Approximate

[tex]\mathbf{y' = -89.6}[/tex]

Hence, the rate of change of the mass position at 2.1 seconds is -89.6 cm/ s

Answer:

0

Step-by-step explanation:

( x1, y1 ) = ( - 4, - 2 )

Here,

x1 = - 4

y1 = - 2

( x2, y2 ) = ( - 4, 22 )

Here,

x2 = - 4

y2 = 22

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope

= ( 22 - ( - 2 ) ) / ( - 4 - ( - 4 ) )

= ( 22 + 2 ) / ( - 4 + 4 )

= 24 / 0

= 0

Answer:

2 metres per 1 hour

12 metres per 6 hours

30 minutes to glide 1 metre.

Step-by-step explanation:

1. To find the average speed, simply divide the distance covered by the amount of time taken, like so:

4 metres / 2 hours = 2 metres per 1 hour

2. To find how many metres the snail will glide in 6 hours, multiply the 2 metres per 1 hour by 6, like so:

6(2 metres per 1 hour) = 12 metres per 6 hours

3. Because we know that 2 metres take 1 hour to glide over, if we divide 2 in half, we get 1, so we can also divide 1 hour in half to get 30 minutes. Therefore, it takes 30 minutes to glide 1 metre.

Answer:

132

Step-by-step explanation:

Answer:

132°

Step-by-step explanation:

Because the triangle is isosceles, the two base angles are the same. This means that two angles in the triangle are 24°

24 + 24 + ∠PON = 180° - first, simplify this

48 + ∠PON = 180° - now, subtract 48 from both sides

∠PON = 132°

Answer:

25,160

Step-by-step explanation:

17,000 x 0.04 = 680

Town gains 680 people every year.

After 12 years, town will have 25,160 people.

This could also be wrong because it may be 4%+ the added people from the previous number. However, I think it is 25,160.

Answer:

Step-by-step explanation:

so lets call shelf 1 x

shelf 2 is twice size + 18 of shelf 1 so it is 2(x)+18

shelf 3 is 12 less than shelf 1 so x-12

shelf 4 is four more so x+4

Add them all together and it should be 5x+10= 2.5 m or 250 cm

Solve for x using cm

then plug into shelf 2 equation

Answer:

Step-by-step explanation:

Parallel line have the same slope.  Put the reference line is y=mx+b format.  m will be the slope.  A parallel line must have the same m.  Example:

y=2x+5 has a slope of 2 and a y-intercept of 5 (the value of y when x is 0).  Any line witrh the same slope will be parallel.  So with can write y=2x+b, where we'll change the y-interecpt so the the lines don't overlap.  Once we know the parallel line must be y = 2x+b, we can enter the known point, e.g., (3,14), and calculate b:

y=2x+b

14=2*3+b

14=6+b

b=8

The parallel line to y=2x+5 is y=2x+8:  It is parallel and goes through the point (3,14).
