Answer:

I think option C is the answer

Answer:

45.82 square inches

Step-by-step explanation:

Use the formula for the surface area of a sphere, A = 4[tex]\pi[/tex]r²

If the diameter is 3.82 inches, the radius is 1.91 inches.

Plug in 3.14 as [tex]\pi[/tex] and 1.91 as r, and solve:

A = 4[tex]\pi[/tex]r²

A = 4(3.14)(1.91²)

A = 45.82

So, approximately 45.82 square inches of material are needed.

Answer:

y = 10/8 = 1.125 or 1 1/4

Step-by-step explanation:

Inverse proportion means

xy = a constant.

In this case, the constant is given by the example,

x = 2 when y=5, so

xy=10

when x = 8, then

y = 10/8 = 1.125 or 1 1/4

Answer:

1/4

Step-by-step explanation:

Answer:

a) 201s / 1000

b) 7s / 125 + s / 10 + 7s / 5 + s / 30 + s / 2

Step-by-step explanation:

Total de miembros de la familia = 4

Ganancia de la madre = s / 1000 por mes

Ganancia del papa = s / 40 por semana

Ganancia por venta de huevos = s / 10

Ganancia total por mes = s / 1000 + s / 40 * 4 + s / 10 = s / 1000 + s / 10 + s / 10 = 201s / 1000

Gasto-

Servicio - S / 250 * 4 = 4s / 250

ropa - 4S / 40

servicios de agua - 4S / 30

Electricidad - 4S / 100

paquete de teléfono, internet y cable - S / 120

alimento para pollos - S / 15 cada mes

higiene personal 4S / 20

4 mascarillas de tela - 4S / 10

4 litros de alcohol - 4 S / 8

3 litros de lejía - 3S / 5

Gastos totales = 2s / 125 + s / 10 + 2s / 15 + s / 25 + s / 120 + s / 40 + s / 15 + s / 5 + 2s / 5 + s / 2 + 3S / 5

Gasto total = 7s / 125 + s / 10 + 7s / 5 + s / 30 + s / 2

Answer:

it’s 22

Step-by-step explanation:

I put -6,28 and it was wrong

The product of the vectors v1 and v2 is 22

How to determine the product?

The vectors are given as:

V1 = (3,7) and V2 = (-2,4)

The product of v1 and v2 is calculated using:

v1v2 = v1x * v2x + v1y* v2y

So, we have:

v1v2 = 3 * -2 + 7 * 4

Evaluate

v1v2 = 22

Hence, the product v1v2 is 22

Answer:

A point on the circumference of the tire will travel 7.68 ft.

Step-by-step explanation:

Given;

radius of the car tire, r = 1.6 ft

angular distance or rotation = 275⁰

A complete rotation of the tire = 360⁰

the distance a point on the circumference will travel = 2πr

If 360⁰ = 2πr

then 275⁰ = ?

[tex]= \frac{275 \ \times \ 2\pi r}{360} = \frac{275 \ \times \ 2\pi \times 1.6ft}{360} = 7.68 \ ft[/tex]

Therefore, a point on the circumference of the tire will travel 7.68 ft.

Answer:

55

Step-by-step explanation:

You're looking at a right triangle, with both legs being complementary forming 90

Since you know one measurement, 35, substract that from 90 and you get your missing angle.

90-35 = 55

Answer:

measure of the missing angle=55°

Step-by-step explanation:

Hi there!

We're given a right angle (as indicated by the red marking) being split into a 35° angle and another angle of unknown degree. Let's call the value of this angle x.

Because the given angle is 90° being split apart by the 35° angle and x, x+35° will equal to 90° (this is called parts whole postulate, where a whole (the 90° angle) is equal to the sum of its parts (the 35° angle and the x° angle))

so we can solve the equation as:

x+35°=90°

subtract 35 from both sides

x=55°

so the measure of the missing angle is 55°

Hope this helps! :)

Answer:

3(2x + 1)(3x - 5)

Step-by-step explanation:

Given

18x² - 21x - 15 ← factor out 3 from each term

= 3(6x² - 7x - 5 ) ← factor the quadratic

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 6 × - 5 = - 30 and sum = - 7

The factors are + 3 and - 10

Use these factors to split the x- term

6x² + 3x - 10x - 5 ( factor the first/second and third/fourth terms )

3x(2x + 1) - 5(2x + 1) ← factor out (2x + 1) from each term

(2x + 1)(3x - 5)

Then

18x² - 21x - 15 = 3(2x + 1)(3x - 5)

The value of 6P6 is 720

How to evaluate the expression?

The expression is given as:

6P6

This is calculated using:

[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]

So, we have:

[tex]^6P_6 = \frac{6!}{(6 - 6)!}[/tex]

Evaluate the difference

[tex]^6P_6 = \frac{6!}{0!}[/tex]

As a general rule;

0! = 1

So, we have:

[tex]^6P_6 = 6!\\[/tex]

Expand

[tex]^6P_6 = 6 * 5 * 4 * 3 * 2 * 1[/tex]

Evaluate

[tex]^6P_6 = 720[/tex]

Hence, the value of 6P6 is 720

The roots: this is when y=0, so in yours there are 2 roots. Just look at the x value when y=0 and that is your roots.

Y intercept- this is when x=0, so just look at the y value below x=0 and that is the y intercept. Note the answer will probably be in the form (0,_)

Vertex=do you see a pattern? Well the vertest would be the highest or lowest point of the quadratic equation. Your vertex would be (5,-9) because just look at x=4 and x=6, bit of the y values are -8 and when you look at x=3 and x=7 they are also the same because this is a quadratic equation.

Max or min: yours is a minimum because (5,-9) is the lowest point. Every value left and right of this are higher up the graph, so this would be a minimum.

Algebra

For example, (x)(x)=x^2

Add the exponents of the variable to get the correct answer.

(k^3)(k^5)=k^8

Answer and Step-by-step explanation:

When two values have the same base, have exponents, and are being multiplied to each other, then we add together the exponents.

So, we are given k to the power of 3, which is multiplied by k to the power of 5. The powers (exponents) are added together to make 8, and the bases combine to be only one of the bases, being k.

So, we are left with the answer being [tex]k^8[/tex].

Answer:

A) 1 = 0.16 = 16%

2) $4.69

B) 1 = 0.04 = 4%

2) $4.76

Step-by-step explanation:

A gallon of milk that cost $3.89 a year ago now costs $4.05.

A. Linear Growth rate formula:

P(t) = Po + rt

P(t) = Cost After t years = $4.05

Po = Initial cost = $3.89

1) If the cost is increasing linearly, what is the growth rate?

When t = 1

P(t) = Po + rt

4.05 = 3.89 + r × 1

r = 4.05 - 3.89

r = 0.16

Converting to percentage

= 0.16 × 100

= 16%

2) If the cost kept increasing in the same way, what will the milk cost 5 years from now?

P(t) = Po + rt

P(t) = 3.89 + 0.16 × 5

P(t) = 3.89 + 0.8

P(t) = 4.69

= $4.69

B. Exponential growth rate formula

P(t) = Po (1 + r)^t

If the cost is increasing exponentially, what is the growth rate?

1) when t = 1

P(t) = Cost After t years = $4.05

Po = Initial cost = $3.89

4.05 = 3.89 (1 + r)

Divide both sides by 3.89

4.05/3.89 = 3.89(1 + r)/3.89

1.0411311054 = 1 + r

r = 1.0411311054 - 1

r = 0.0411311054

Approximately = 0.04

Converting to Percentage

= 4%

2) What will the milk cost in 5 years?

P(t) = 3.89 (1 + r)^t

P(t) = 3.89 (1 + 0.0411311054)⁵

= $4.7585727225

Approximately = $4.76
