Please help me....Use the Pythagorean identity

Answers

Using the Pythagorean identity, the value of the cosine ratio is [tex]\cos(\theta_1) = \frac{84}{85}[/tex]

How to determine the cosine ratio?

The given parameter is:

[tex]\sin(\theta_1) = -\frac{13}{85}[/tex]

By the Pythagorean identity, we have:

[tex]\sin^2(\theta_1) + \cos^2(\theta_1) = 1[/tex]

So, we have:

[tex](-\frac{13}{85})^2 + \cos^2(\theta_1) = 1[/tex]

This gives

[tex]\cos^2(\theta_1) = 1 - (-\frac{13}{85})^2[/tex]

Evaluate

[tex]\cos^2(\theta_1) = 1 - \frac{169}{7225}[/tex]

Take LCM

[tex]\cos^2(\theta_1) = \frac{7225 -169}{7225}[/tex]

This gives

[tex]\cos^2(\theta_1) = \frac{7056}{7225}[/tex]

Take the square root of both sides

[tex]\cos(\theta_1) = \pm \frac{84}{85}[/tex]

Cosine is positive in the fourth quadrant.

So, we have:

[tex]\cos(\theta_1) = \frac{84}{85}[/tex]

Hence, the cosine value is [tex]\cos(\theta_1) = \frac{84}{85}[/tex]

Sofia works in a clothing store and earns $40 per day. She earns an extra $5 for each outfit she sells. If Sophia wants to earn at least $70 per day, which inequality shows the minimum number of outfits, n, that she should sell

Answers

Answer:

70= 5n+40

Step-by-step explanation:

(n=6 if you need it)

Hope this helps! ;-)

In order to find this answer, you will need to be able to make an inequality.

Step 1: Sophia makes $40 so start with that. 40

Step 2: Sophia also makes $5 per every outfit that she sells, so add that plus your variable (n). 40+5n

Step 3: Determine if Sophia wants to make more, equal to or more, less, or less than or equal to than what she wants to make per day. 40+5n *draw a greater than or equal to sign.

Step 4: Sophia wants to make more than or equal to what she makes per day. You will need to find what she wants to make more than. In this she wants to make more than or equal to $70.

Equation: 40+5n *greater than or equal to sign* $70

Find the surface area and lateral area of the following three prisms. Be sure to show all of your work.

Answers

Problem 1

L = 10 = length

W = 5 = width

H = 4 = height

SA = surface area of a rectangular prism, aka block or box

SA = 2*(LW+LH+WH)

SA = 2*(10*5+10*4+5*4)

SA = 220

--------------------

LA = lateral area, aka wall area

LA = (perimeter of the base)*(height)

LA = (2L+2W)*H

LA = (2*10+2*5)*4

LA = 120

or

LA = SA - (floor area) - (ceiling area)

LA = SA - 2*(area of the floor)

LA = 220 - 2*(LW)

LA = 220 - 2*(10*5)

LA = 220 - 100

LA = 120

--------------------

Answers:

Surface Area = 220 square feet

Lateral Area = 120 square feet

==========================================================

Problem 2

Imagine rotating the object so that the triangular face is resting on the flat ground. This means the triangular faces are the floor and ceiling. The walls of any prism are always rectangles.

Focus on the right triangle with leg b = 4 and hypotenuse c = 5.

Use the pythagorean theorem to find that a = 3 is the missing leg length.

The triangle has base = 4 and height = 3, so its area is base*height/2 = 4*3/2 = 6 square inches. This is the area of the floor and ceiling each.

--------------------

This is the summary so far

base or floor area = 6 square inchesdepth of the prism = 8 inches(a,b,c) = (3,4,5) are the sides of the right triangle

Those values are then plugged into the formulas below.

SA = surface area of a triangular prism

SA = 2*(base area) + depth*(a+b+c)

SA = 2*(6) + 8*(3+4+5)

SA = 108

LA = lateral area

LA = depth*(a+b+c)

LA = 8*(3+4+5)

LA = 96

or

LA = SA - 2*(floor area)

LA = 108 - 2*(6)

LA = 96

Note that a+b+c = perimeter of the triangular base.

--------------------

Answers:

Surface Area = 108 square inches

Lateral Area = 96 square inches

==========================================================

Problem 3

Imagine rotating the figure so that the octagon is resting on the flat ground.

Refer to the screenshot below to see the steps on computing the area of the regular octagon, aka the floor area.

The floor area is approximately 120.710678 square cm. The same goes with the ceiling because the floor and ceiling are congruent regular octagons that are parallel.

Each rectangular wall has an area of 5*22 = 110 square cm. Eight identical walls give a total lateral area of 8*110 = 880 square cm.

Add the floor and ceiling area to the wall area to get the total surface area

floor + ceiling + walls = 120.710678 + 120.710678 + 880 = 1121.421356

--------------------

Answers:

Surface Area = 1121.421356 square cm (approximate)

Lateral Area = 880 square cm

substitution. y = x − 35 y=-4x

Answers

Answer:

(7, - 28 )

Step-by-step explanation:

y = x - 35 → (1)

y = - 4x → (2)

substitute y = x - 35 into (2)

x - 35 = - 4x ( add 4x to both sides )\

5x - 35 = 0 ( add 35 to both sides )

5x = 35 ( divide both sides by 5 )

x = 7

substitute x = 7 into either of the 2 equations

substituting into (1)

y = 7 - 35 = - 28

solution is (7, - 28 )

Al pagar una cuenta de S/ 143 se le cobró una mora del 10%. ¿Cuál era el pago original?

Answers

Teniendo en cuenta la definición de porcentaje, el pago original sin la mora del 10% es 130.

Definición de porcentaje

El porcentaje es una forma de referirse a una proporción tomando como referencia el número 100.

En otras palabras, el porcentaje es una fracción o una parte de 100, denominándose también como tanto por ciento, y se indica con el símbolo %.

Es decir, el porcentaje es la forma de expresar un número como una fracción que tiene como denominador el número 100 y representa la porción de un todo, que se obtiene dividiendo el monto conocido entre el total y multiplicándolo por 100.

Pago original

El pago original es 100%. Al cobrarse una mora del 10%, se debe pagar 110% del pago original, representada por la letra P.

Entonces:

110%×P=143

Resolviendo:

P= 143 ÷ 110%

Considerando que un porcentaje es una cantidad determinada de cada 100 unidades, entonces  110 % significa 110 de cada 100 unidades, y es equivalente a 110/100. Entonces:

P=143 ÷ [tex]\frac{110}{100}[/tex]

P= 130

Entonces, el pago original sin la mora del 10% es 130.

Austin uses a mold to make cone-shaped cupcakes. The diameter of the mold is 12 inches, and
the height of the mold is 10 inches. If one cubic inch is about 0.55 ounce, how many ounces will
2 cupcakes weigh? Use 3.14 for T. Round to the nearest tenth of an ounce. Only write the
number

Answers

Answer:

25.9

Step-by-step explanation:

So calculate volume of the mold, which is a cone: (pi) r2 (h/3) where r is radius and h is height

So diameter/2 = r which is 1.5 in

h = 2 in

V = (3.14)(1.52)(2/3) = 4.71 in3

If 1 in3 = 0.55 oz, and 1 mold = 4.71 in3, then one mold = 2.59 oz

2.59 oz * 10 cupcakes = 25.9 oz total

Step-by-step explanation:

the volume of a cone is

pi×r² × h/3

the radius is always half of the diameter, so, it is here

12/2 = 6 in.

h = 10 in.

so, we have here

pi×6²×10/3 = 3.14 × 36 × 10/3 = 3.14×120 = 376.8 in³.

2 cupcakes have then

376.8 × 2 = 753.6 in³

1 in³ = 0.55 ounces

so, the weight of 2 such cupcakes is

0.55 × 753.6 = 414.48 ounces ≈ 414.5 ounces

Answers

The expression that represents the volume of the empty space is  9³ -  4 / 3 π(4.5)³ cubic units.

How to find the expression for volumes?

The volume of the empty space can be represented as follows

volume of the empty space = volume of cube - volume of sphere

Therefore,

volume of sphere = 4 / 3 πr³

where

r = radius

Volume of cube = L³

where

L = side length

Therefore,

volume of cube = 9³

volume of sphere = 4 / 3 π(4.5)³

Hence,

volume of the empty space = 9³ -  4 / 3 π(4.5)³
