There are 6 blades on each windmill .how many are there in 7 windmil

2 answers:

7 0

Well if you take 6x7 you get 42. If each windmill has 6 blades on it and there are 7 windmills you just take those two numbers and multiply them.

6 blades in 1 windmill is the "unit rate" A unit rate is the number per thing. You will need to multiply. Multiply 6X7. 6 for 6 blades and 7 for 7 windmills. It is 42. 42 blades are in 7 windmills.

At time t=0 water begins to drip out of a pipe into an empty bucket. After 56 minutes 8 inches of water are in the bucket. What

oksano4ka [1.4K]

Answer:

The linear function of the bucket is $y = \frac{1}{7}\cdot x$ , where $y$ represents the amount of water, measured in inches, and $x$ is the time, measured in minutes.

Step-by-step explanation:

According to the Euclidean and Analytical Geometries, we can construct a line by knowing two distinct points on a plane. Besides, we know two different conditions for the bucket:

Initial condition of the bucket

$A(x,y) = (0\,min, 0\,in)$

Final condition of the bucket

$B(x,y) = (56\,min, 8 in)$

The equation of the line is defined by the following model:

$y = m\cdot x + b$ (1)

Where:

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

$b$ - y-Intercept, dimensionless.

$m$ - Slope, dimensionless.

Based on the known conditions of the bucket, we obtain the following system of linear equations:

$b = 0$ (2)

$56\cdot m +b = 8$ (3)

The solution of the system of equations is:

$m = \frac{1}{7}$ and $b = 0$

Then, the linear function of the bucket is $y = \frac{1}{7}\cdot x$ , where $y$ represents the amount of water, measured in inches, and $x$ is the time, measured in minutes.

Kevin is 4 times as old as Daniel and is also 6 years older than Daniel

MAXImum [283]

Answer:

Part a) Daniel's age is 2 years

Part b) Kevin's age is 8 years

Step-by-step explanation:

The question is

Part a) How old is Daniel?

Part b) How old is Kevin?

Let

x ----> Kevin's age

y ----> Daniel's age

we know that

$x=4y$ -----> equation A

$x=y+6$ ----> equation B

Equate equation A and equation B

$4y=y+6$

solve for y

$4y-y=6$

$3y=6$

$y=2$

therefore

Daniel's age is 2 years

Find the value of x

substitute the value of y in any of the two equations

$x=4(2)=8\ years$

$x=2+6=8\ years$

therefore

Kevin's age is 8 years
