Is this true or false? Pls help a dumb person out

Answer:

9

Step-by-step explanation:

formula for inverse proportion is y = [tex]\frac{k}{x}[/tex]

k is the constant of probability

to find k,

y is 12, x is 6

12 = [tex]\frac{k}{6}[/tex]

so x = 12 × 6

∴ k is 72

so y = [tex]\frac{72}{8}[/tex]

∴ y is 9

Cost per metre = Rs. 5

Total cost = Rs. 2000

Then total length of the fence = Rs.2000/Rs.5

= 400 metre

Total length of the fence = 400 metre

Complete question :

Ann, Brian and Carol share the cost of a car. Ann pays 2/5 of the cost, Brian pays 1/3 and Carol pays the rest.

a) What fraction of the cost does Carol pay?

b) Ann pays $1600 more than Brian. Find the total cost of the car.

Answer:

4/ 15

8000

Step-by-step explanation:

A)

Fraction carol paid :

Total fraction = 1/1

Fraction paid by Ann and Brian = (2/5 +1/3)

(2/5 + 1/3) = (6 + 5) / 15 = 11/15

1 - 11/ 15 = 4/ 15

Ann = 2/5 ; Brian pays 1/3

Ann pay 1600 more than Brian

2/5 - 1/3 = (6 - 5) = 1/5

1/5 of amount = 1600

If :

1/5 = 1600

1 = x

1/5x = 1600

x = 1600 ÷1/5

Total amount = 8000

Step-by-step explanation:

To factor a polynomial, first identify the greatest common factor of the monomial terms. Then use the Distributive Property to rewrite the polynomial as the product of the GCF and the other parts of the polynomial. (Remember, the distributive property says that a(b + c) = a • b + a • c.)

To factor a polynomial, first identify the greatest common factor of the monomial terms. Then use the Distributive Property to rewrite the polynomial as the product of the GCF and the other parts of the polynomial

A number system is defined as a system of writing to express numbers.

The relationship between using the Distributive Property to simplify an expression and to factor an expression is given here.

The distributive property tells that

a(b-c)=ab-ac and a(b+c)=ab+ac

It means you can separate the common term and represent it as the factor.

Example 12x+4y

The factors of 12 are 4,3

The factor of 4 are 1,2,4

The common factor is 4.

12x+4y=4(3x+y)

We taken out the common factor and has distributive property.

Hence To factor a polynomial, first identify the greatest common factor of the monomial terms. Then use the Distributive Property to rewrite the polynomial as the product of the GCF and the other parts of the polynomial

Derivative of cos(x)=-sin(x)

Derivative of e^x=e^x

Derivative of cos(x)-e^x= - sin(x)-e^x

plug in 0 to the spots of x and you will get 1 because sin(0) is 0 e^0 is 1

Answer: 46.90mins

Step-by-step explanation:

The given data:

The diameter of the balloon = 55 feet

The rate of increase of the radius of the balloon when inflated = 1.5 feet/min.

Solution:

dr/dt = 1.5 feet per minute = 1.5 ft/min

V = 4/3·π·r³

The maximum volume of the balloon

= 4/3 × 3.14 × 55³

= 696556.67 ft³

When the volume 2/3 the maximum volume

= 2/3 × 696556.67 ft³

= 464371.11 ft³

The radius, r₂ at the point is

= 4/3·π·r₂³

= 464371.11 ft³

r₂³ = 464371.11 ft³ × 3/4

= 348278.33 ft³

348278.333333

r₂ = ∛(348278.33 ft³) ≈ 70.36 ft

The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)

The time for the radius to increase to the

above length

Time taken for the radius to increase the length.

= is 70.369 ft/(1.5 ft/min)

= 46.90 minutes

46.90mins is the time taken to inflate the balloon.

Second rectangle and third rectangle are resulting rectangles scale drawings of one another

The area of Rectangle is length times of width.

Given,

Gayla draws a rectangle.

Second rectangle:

Jared then draws a different rectangle by increasing both the length and the width by 5%.

Third rectangle:

Lyda draws a third rectangle by increasing both the length and the width of Gayla’s by 5 inches.

Let us assume 1 inches as 1 percentage.

So second rectangle and third rectangle are resulting rectangles scale drawings of one another

Hence,  second rectangle and third rectangle are resulting rectangles scale drawings of one another
