There are 1.5 revolution in one second.

What is relation between minute and seconds?

The relation between minute and seconds is;

1 minute = 60 seconds

A windmill makes 90 revolutions in one minute.

Now, In one minutes number of revolution = 90

Since, 1 minute = 60 seconds

Hence, In 60 second number of revolution = 90

In 1 second number of revolution = 90/60 = 1.5

So, There are 1.5 revolution in one second.

Therefore, There are 1.5 revolution in one second.

Answer:

n=35; q=33 coins.

Step-by-step explanation:

1) if number of nickles is 'n' and the quaters is 'q' then it is possible to write:

n+q=68 - 'she counted 68 coins...' - the 1st equation of system;

0.25q+0.05n=10 - '10$ in it' - the 2d equation of the system.

2) it is possible to make up and solve the next system of two equations:

[tex]\left \{ {{q+n=68} \atop {0.25q+0.05n=10}} \right. \ => \ \left \{ {{q=33} \atop {n=35}} \right. .[/tex]

Answer:

Step-by-step explanation:

It would take 220 minutes for Angela's and Benjamin's monthly bills be the same

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the cost after x minutes, hence:

For angela:

y = 0.15x + 49

The y intercept is $49 and the rate of change is $0.15 per minute

For Benjamin:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-60=\frac{80-60}{200-0} (x-0)\\\\y=0.1x+60[/tex]

The y intercept is $60 and the rate of change is $0.10 per minute

For 200 minutes:

Angela: y = 0.15(200) + 49 = $79

Benjamin: y = 0.10(200) + 60 = $80

To be the same:

0.15x + 49 = 0.1x + 60

x = 220 minutes

It would take 220 minutes for Angela's and Benjamin's monthly bills be the same

Answer:

64p and 69p

the first shop has better value than second

Step-by-step explanation:

you are basically looking for which shop is gives the best price per SINGLE can.

for the first shop we divide the price which is 5.77 by 9 to get the price of a single can.

5.77 divide by 9 makes 0.64111111111...

the question say to round it to the nearest penny so the price for won can in the first shop is 64p

we do the same for the second shop which is.

4.13 decide 6 makes 0.688333333...

so the price/value for a single can is 69p since we round it up to nearest penny.

the first shop give better value since each can is 5pennys shorter than the second shop.

Answer:

chicken= $10.20

beef= $12.90

the difference between them is $2.70

Step-by-step explanation:

so you do 3.40 *3 and get 10.20.

then 4.30*3 and get 12.90

then 12.90- 10.20= $2.70

Answer:

1 pound of chicken costs=$3.40

3 pounds of chicken costs=3×3.40

=$10.2

1 pound of beef costs=4.30

3 pounds of beef costs=3×4.30

=$12.9

Now,

How much more does the beef cost?

=12.9--10.2

=$2.70

Answer:

We know blend A costs 5.50 and blend B costs 4.30. We know that Pablo made 153 pounds of coffee this month. Let's let A=amount of blend A used and B=amount of blend B used. Since he made 153lbs coffee, we know that

A+B=153.

But he spent 756.30. The total amount he spent on a blend of coffee is the price * amount used. So he spent 5.50*A on blend A and 4.30*B on B, so in total, he spent 5.50*A+4.30*B in coffee. But this must add to 756.30! So

5.5A+4.3B = 756.30

Now we have two equations:

A+B = 153

5.5A + 4.3B = 756.30

We need to solve for B. I hate decimals so let's get rid of them in the second equation by multiplying both sides of the equation by 100 (which simply moves the decimals on everything two to the right). So now we have

A+B = 153

550A + 430 B = 75630

Now let's multiply the first equation by 550 (so we can eventually get rid of pesky A). So multiply the left and right side of the first equation by 550, so we have

550A + 550B = 84150

550A + 430B = 75630

Now subtract the second equation from the first, notice that since both have 550A, they cancel, so we obtain

120B = 8520

Now divide by 120 into both sides to solve for B, we get

B= 8520/120 = 71

So Pablo used 71lbs of blend B.

Using a system of equations, it is found that:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

From Stan's purchases, we have that:

[tex]n + 3p + 2m = 7.5[/tex]

From Jan's purchases, we have that:

[tex]2n + 6p + 5m = 15.50[/tex]

From Fran's purchases, we have that:

[tex]n + 2p + 2m = 6.25[/tex]

From the third equation:

[tex]n = 6.25 - 2p - 2m[/tex]

Replacing on the first:

[tex]n + 3p + 2m = 7.5[/tex]

[tex]6.25 - 2p - 2m + 3p + 2m = 7.5[/tex]

[tex]p = 1.25[/tex]

On the second equation, we have that:

[tex]2n + 6p + 5m = 15.50[/tex]

[tex]2(6.25 - 2p - 2m) + 6(1.25) + 5m = 15.50[/tex]

[tex]2(3.75 - 2m) + 5m = 8[/tex]

[tex]m = 0.5[/tex]

Finally:

[tex]n = 6.25 - 2(1.25) - 2(0.5) = 2.75[/tex]

The percentage set aside for housing is given as 28% which is $1600.

After the reflection:

U: (5,2)

V: (3,1)

W: (3,-3)

Z: (5,-6)

Step-by-step explanation:

To reflect over the x axis, you need to move the point left or right across the x axis (in this case, right) an equal amount of times. Ex: -5, you would move 10 to the right, or 5 to get to 0, then another 5 to equal it out

The disk method will only involve a single integral. I've attached a sketch of the bounded region (in red) and one such disk made by revolving it around the y-axis.

Such a disk has radius x = 1/y and height/thickness ∆y, so that the volume of one such disk is

π (radius) (height) = π (1/y)² ∆y = π/y² ∆y

and the volume of a stack of n such disks is

[tex]\displaystyle V_n = \sum_{i=1}^n \pi {y_i}^2 \Delta y[/tex]

where [tex]y_i[/tex] is a point sampled from the interval [1, 5].

As we refine the solid by adding increasingly more, increasingly thinner disks, so that ∆y converges to 0, the sum converges to a definite integral that gives the exact volume V,

[tex]\displaystyle V = \lim_{n\to\infty} V_n = \int_1^5 \frac{\pi}{y^2} \, dy[/tex]

[tex]V = -\dfrac\pi y\bigg|_{y=1}^{y=5} = \boxed{\dfrac{4\pi}5}[/tex]
