Answer: $4100

Step-by-step explanation:

discount = [tex]\frac{1800}{90}[/tex]×100 = 2000

profit = [tex]\frac{115}{100}[/tex]×2000 = 2300

market price = 2300 + 1800 = 4100

To two decimal places ✓70 just be between 8.36 and 8.37.

It should be noted that we simply have to calculate the information is to find the square root of 70.

Therefore, this is approximately 8.366

Therefore, to two decimal places ✓70 just be between 8.36 and 8.37.

Answer:

A)50°F = 10°C

B)75°C = 167°F

C)-40°C = -40°F

Step-by-step explanation:

A) 50°F = 10°C

Formula

(50°F − 32) × 5/9 = 10°C

B) 75°C = 167°F

Formula

(75°C × 9/5) + 32 = 167°F

C) -40°C = -40°F

Formula

(-40°C × 9/5) + 32 = -40°F

Answer:

Option A: 3, 7, 11, 15

Step-by-step explanation:

f(2) = f(1) + 4 = 3 + 4 = 7

f(3) = f(2) + 4 = 7 + 4 = 11

f(4) = f(3) + 4 = 11 + 4 = 15

f(5) = f(4) + 4 = 15 + 4 = 19

Step-by-step explanation:

so it starts with

182 = 182 × 3 / p

as the price is inversely related to D.

(a)

so, in general

D = 182 × 3/p = 546/p

(b)

D = 546/3.25 = 168 bags

if the price increases to $3.25, then they will sell only 168 bags.

I am sure, the function will not stay linear for every value of p. for example, if they increase the price to $546 per bag, they would still sell 1 bag. but I am certain, they would fall to 0 sold bags much, much earlier than that ...

Answer: 45,000,000,000 dl

Step-by-step explanation:

10,000,000,000 dl=1 gl

4.5 gl * 10,000,000,000 dl/1 gl =

The length of the parallelogram is 16 m and the width of the parallelogram is 12 m.

We are given that the perimeter of a parallelogram is 56 m.

Let the length of the parallelogram be x meter.

So, we get that the width of the parallelogram will be = x - 4 meter.

We also know that:

Perimeter of parallelogram = 2 ( l + b )

Substituting the values in this, we get that:

56 = 2 ( x + x - 4 )

56 = 2 ( 2 x - 4 )

28 = 2 x - 4

2 x - 4 = 28

2 x = 28 + 4

2 x = 32

x = 16

Length = 16 m

Width = 16 - 4 = 12 m

Therefore, the length of the parallelogram is 16 m and the width of the parallelogram is 12 m.

Answer:

Your answer is correct

Step-by-step explanation:

Use the rules of exponents to simplify the expression.

To raise a power to another power, multiply the exponents.

Multiply 6 by 2.

The correct option is the third.

The domain of the function g ( x ) = √ x − 3 / x − 11 is R - 11.

Inputs are assigned outputs by functions. The collection of all potential inputs for a function is its domain. For instance, the domain of f(x)=x2 and g(x)=1/x are all real integers with the exception of x=0.

Consider the function y = f(x), which has the independent variable x and the dependent variable y. A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x.

1) The angular speed is approximately 12.566 radians per second.  

2) The linear speed of a point on the edge of the disk is 1.257 meters per second.

1) Herein we have a disk that spins at constant angular speed (ω), in radians per second, whose magnitude is found dimensional analysis and unit conversions:

ω = 120 rev / min × (2π rad / 1 rev) × (1 min / 60 s)

ω ≈ 12.566 rad / s

The angular speed is approximately 12.566 radians per second.  

2) The linear speed (v), in meters per second, on the edge of the disk is described by the following formula:

v = R · ω  

Where R is the radius of the spinning disk, in meters.

If we know that R = 0.1 m and ω ≈ 12.566 rad / s, then the linear speed is:

v = (0.1 m) · (12.566 rad / s)

v = 1.257 m / s

37.375 kg of peanuts must be added to the 4 kg of mixed nuts to make a mixture containing 92 % of peanuts.

Total mixture of mixed nuts = 4 kg

60 % of them are peanuts.

So, we will calculate the percentage:

Let x be the amount of peanuts.

60 / 100 x = 4 kg

0.6 x = 4 kg

x = 4 kg / 0.6

x = 6.67 kg

Now let the peanuts added be y

So, 92 % of ( 4 kg + y )  should be peanuts.

So, we get the equation as:

0.92 ( 4 ) + 0.92 y = 6.67 + y

3.68 + 0.92 y = 6.67 + y

0.08 y = 2.99

y = 37.375 kg

Therefore, 37.375 kg of peanuts must be added to the 4 kg of mixed nuts to make a mixture containing 92 % of peanuts.
