Answer:

  $62.22

Step-by-step explanation:

Let m represent the pre-tax, pre-tip price of the meal. Then the total cost is ...

  m + tax + tip

  = m + 7%·m +15%·m

  = m(1 +7% +15%) = 1.22m

  = 1.22($51) = $62.22

The total cost of the meal is $62.22.

Answer:

$0.55

Step-by-step explanation:

All you have to do is divide $14.30 by 26 and that equals 0.55 so he spent 55 cents on each sandwich

Answer:

Step-by-step explanation:

Let Eva's height be x

62* 0.5 = x + 1.5

31 = x + 1.5                   Subtract 1.5 from both sides.

31 - 1.5 = x

x = 29.5

Answer:

  y = 1/5x +8

Step-by-step explanation:

The slope of the perpendicular line will be the opposite reciprocal of the slope of the given line:

  m = -1/(-5) = 1/5

The y-intercept (b) can be found from this and the given point:

  b = y -mx

  b = 9 -(1/5)(5) = 8

Then the slope-intercept equation can be written ...

  y = mx +b . . . . . . line with slope m and y-intercept b

  y = 1/5x +8

Additional comment

Since the question asks for "an equation," the problem can be solved even more quickly using the point-slope form of the equation of a line.

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

  y -9 = 1/5(x -5) . . . . . an equation for line j

Answer:

$94105.81

Step-by-step explanation:

[tex]21000( ({1 + .0512675})^{30} - 1) \\ = 73105.81 \\ 73105.81 + 21000 = 94105.81[/tex]

Future value of the investment if the interest is compounded daily is $94,105.80.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

Given that,

Principal amount, P = $21,000

Rate of interest, r = 5% = 5/100 = 0.05

Time, t = 30 years

The final amount in a compound interest is,

A = P (1 + r/n)^(nt), where n is the number of times compounding is done in a year.

Here, n = 365

A = 21000 (1 + 0.05/365)^(365 × 30)

  = 94,105.802

  ≈ 94,105.80

Hence the final amount is $94,105.80.

  f^-1(x) = ∛((x +5)/2)

Step-by-step explanation:

Continue to solve for y.

The exact measurements for the lengths of the other sides of the triangle are 0.52 and 0.73m

To get the measure of the lengths of the other sides of the triangle, we need to get the third side first as shown:

Since the sum of the interior angle of a triangle is 180 degrees, hence;

30 + 45 + x = 180

75 + x = 180

x = 180 - 75

x = 105 degrees

Get the measure of the other sides using the sine rule;

1/sin 105 = x/sin 30 = y/sin 45

Get the measure of angle x

1/sin 105 = x/sin 30

x sin 105 = sin 30

x sin 105 = 0.5

x = 0.5/sin 105

x = 0.52m

1/sin 105 = x/sin 30 = y/sin 45

Get the measure of angle x

1/sin 105 = y/sin 45

y sin 105 = sin 45

x sin 105 = 0.0.7071

x = 0.7071/sin 105

x =  0.73m

Hence the exact measurements for the lengths of the other sides of the triangle are 0.52 and 0.73m

Answer: Its 2 seconds

Step-by-step explanation:

I took the quiz

The object reach its maximum height at 2 seconds.

WE are the given curve shows the height of an object which has been launched from 50 foot high wall with respect to time.

So we can see that the curve initially starts from the height of 50 feet.

Here in the middle the height of the object is maximum and immediately after that the height decreased in the graph.

At that maximum height time from the graph we can find that the height of the object goes upto 106 feet.

We can see in the graph that it hits the ground when the height is equal to 106.

Answer:

  13 costumes

Step-by-step explanation:

The amount of fabric used is the product of the amount per costume and the number of costumes.

  A = na . . . . . A = total area; n = number of costumes; 'a' = area per costume

  46 2/3 = n(3 1/2)

  n = (46 2/3)/(3 1/2) = (140/3)/(7/2) = (140/3)(2/7) = 40/3 = 13 1/3

Apparently there is some waste, as Emerson used more fabric than necessary to make 13 costumes.

Answer:

Step-by-step explanation:

-5 times -2= 10

Given

2x³ + (x³ - 3) sin(2πy) - 3y = 0

we first notice that when x = ³√3, we get

2 (³√3)³ + ((³√3)³ - 3) sin(2πy) - 3y = 0

2•3 + (3 - 3) sin(2πy) - 3y = 0

6 - 3y = 0

3y = 6

y = 2

Differentiating both sides with respect to x gives

6x² + 3x³ sin(2πy) + 2π (x³ - 3) cos(2πy) y' - 3y' = 0

Then when x = ³√3, we find

6(³√3)² + 3(³√3)³ sin(2π•2) + 2π ((³√3)³ - 3) cos(2π•2) y' - 3y' = 0

6•³√9 + 3•3 sin(4π) + 2π (3- 3) cos(4π) y' - 3y' = 0

6•³√9 + 0 + 0 - 3y' = 0

3y' = 6•³√9

y' = 2•³√9

(that is, 2 times the cube root of 9)
