A box of 500 envelopes costs $14.89. Before buying, Mr. Ruiz wants to know the price for one envelope. His son Alan quickly makes a calculation and says, "You can buy almost 34 envelopes for $1.00." Here is Alan's work. 500 500 +14.89 33.6 $14.89 $ 14.89 +14.89 $1.00 Mr. Ruiz thanked his son, but said that was not the answer he was looking for. What is the cost for one envelope to the nearest whole number in cents?

slope intercept form is y = mx + b

where m = slope

for the third one m = 3

Answer:

Step-by-step explanation:

-6 3/5 - (-7 4/15) + 2 1/5

Combine the first and third terms first

-6 3/5 + 2 1/5 = - 4 2/5

Now deal with the second term

- (- 7 4/15) = 7 4/15

7 4/15 - 4 2/5      

7 4/15 - 4 6/15           Add 15/15 to 7 4/15 Subtract 1 from the 7

6 19/15 - 4 6/15

2 13/15

1) To get the present value, we need to get the amount after 5.5years

Amount = Principal + Interest

Interest = PRT/100

Interest = $19,513.75*3*5.5/100

Interest = 321,976.875/100

Interest =  $3219.76875

Amount = $19,513.75+$3219.76875

Amount = 22,733.51875

Hence the present value is $22,733.51875

2) Simple Interest = PRT/100

Simple Interest = 5000*(4 3/4)* 18/12*100

Simple interest = 5 * 19 * 18/4*12

Simple interest = 1710/48

Simple interest =35.625

Amount = 5000 + 35.625

Amount = $5035.625

Hence the present value is $5035.625

Answer:

A = 30°

x = 9·√3

Step-by-step explanation:

Part A

In the drawing, we are given;

The radius of the circle with center at point S = SA = 18

ΔAHA is a right triangle

One of the leg length of ΔASH = 9

The length of the hypotenuse side of ΔASH, AS = 18 The radius of the circle with center at the point 'S'

By Pythagoras's theorem, the length of the (radius) side, AS  = √(SH² + AH²)

∴ AH = √(AS² - SH²)

AH = √(18² - 9²) = √(243) = 9·√3

AH = 9·√3

By circle theorem, SH bisects the line AH extended to the circumference of the circle

SH bisects the line with length AH + x

∴ AH = x

x = AH = 9·√3

x = 9·√3

Part B

By trigonometric ratios, we have;

[tex]sin\angle A = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

[tex]\therefore sin\angle A = \dfrac{9}{18} = \dfrac{1}{2}[/tex]

∠A = arcsine (1/2) = 30°

Angle A = 30°

Answer:

3 cars and 4 buses

Step-by-step explanation:

Let x = cars

Let y = buses

7 vehicles

x + y = 7

cars hold 5 students and each bus holds 45 students

5x + 45y = 195

Solve using subbstitution

x + y = 7

x = 7 - y

5x + 45y = 195

5(7 - y) + 45y = 195

35 - 5y + 45y = 195

35 + 40y = 195

-35             -35

40y = 160

y = 4 (buses)

x + y = 7

x + 4 = 7

x = 3 (cars)

Answer:

Volume = 100 [tex]in^{3}[/tex]

Step-by-step explanation:

Volume, V= Bh

length = 10 inches

width = 5 inches

height = 2 inches

So that,

B = 5(10)

  = 50 [tex]in^{2}[/tex]

B = 50 [tex]in^{2}[/tex]

Then,

V = (50)(2)

Answer:

B) 46 ounces

Step-by-step explanation:

1 pound is 16 ounces, so 16*2 = 32 + 14 = 46!

The weight of bananas in ounce is 46 ounces.

The same attribute is expressed using a unit conversion, but in a different unit of measurement.

For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

Tanya bought a bunch of bananas that weighed 2 pounds 14 ounces.

as, 1 pound = 16 ounces

So, the weight of bananas in ounce is

= 2 x 16 + 14

= 32 + 14

= 46 ounces

Answer:

The answer is "Rotation and dilation".

Step-by-step explanation:

The rotation is a spatial movement, which maintains at least one stage. The dilation of a transition affects a figure's dimensions. The center, as well as a scale factor k, are required Which meaning k determines if the expansion is an expansion or a decrease, therefore the above choice is correct because it just rotated and dilated from its original form.

Answer:

x = 10.25°

Step-by-step explanation:

Given that :

(5x+24°) and (9x-17°)

If both angles are congruent ;

(5x+24°) =(9x-17°)

5x - 9x = - 17 - 24

-4x = - 41

x = 10.25°

Hence, the value of x = 10.25°

Step-by-step explanation:

129/50 = 2.58

Number equivalent to 129 /50 is 2.58 .

Given,

129 divided 50

Using division property,

The rules for division are:

(1) positive × or ÷ positive = positive

(2) positive × or ÷ negative = negative

(3) negative × or ÷ negative = positive

Rule for long division method,

Divide the tens column dividend by the divisor.

Multiply the divisor by the quotient in the tens place column.

Subtract the product from the divisor.

Bring down the dividend in the ones column and repeat.

Therefore,

divide, multiply, subtract, bring down and repeat or find the remainder.

Answer:

  y = 7/3x +13/3

Step-by-step explanation:

The equation of the given line is in slope-intercept form (y=mx+b), so we can see the slope (m) is -3/7. The slope of the perpendicular line is the opposite reciprocal of this, so is ...

  m = -1/(-3/7) = 7/3

The y-intercept of the perpendicular line can be found from ...

  b = y -mx

  b = -5 -(7/3)(-4) = -15/3 +28/3 = 13/3

Then the slope-intercept equation of the perpendicular line is ...

  y = mx +b

  y = 7/3x +13/3

_____

Additional comment

You can get there a little faster using the point-slope form of the equation of a line. For slope m and point (h, k) that form is ...

  y -k = m(x -h)

For our perpendicular line, the equation is ...

  y +5 = 7/3(x +4)
