Answer:

$\frac{11}{10}$

Step-by-step explanation:

In a particular month solitaire's solar panels generate 110% as much as power as expected.

This means 10% more power was generated in a particular month.

But we have to calculate the fraction of the expected amount of power.

Fraction will be $\frac{110}{100}$ = $\frac{11}{10}$

Answer:

If the solar panels produced 110% as much power as expected that means they generated 10% more than planned.

Even though there is 10% more than what was expected they still generated 100% of all energy planned

Because of this we know that they produced 110/100 of power expected as a fraction, or 11/10

6. Solve the the following system of equations: 4y+2x=14 2y+2x=10

Inessa05 [86]

4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14
Now add it up to the 2nd equation
-4y-2x=-14
2y+2x=10
-------------- And now add them up
-2y +0x=-4
==> -2y=-4==> 2y = 4 & y=2
Last step: plug y into any equation & you will find x=3

Q1. An airplane flies with a constant speed of 600 miles per hour. How far can it travel in 3 1/2 hours?

Dahasolnce [82]

Answer:

Q1. 1050 miles

Q2. 1h 30m

Step-by-step explanation:

Q1. 1h = 300 miles

3 $\frac{1}{2}$ h = 3.5 × 300 miles

= 1050 miles

Q2. 68km = 1h

102km = $\frac{102}{68}$ × 1h

= 1.5h

= 1h 30m

Farmer Jones raises ducks and cows. He looks out his window and sees 54 animals with a total of 122 feet. If each animal is “nor

Olenka [21]

Answer:

He have 47 ducks and 7 cows.

Step-by-step explanation:

Given:

Farmer Jones raises ducks and cows.

He looks out his window and sees 54 animals with a total of 122 feet.

Now, to find the each type of animal he have.

Let the number of ducks be $x.$

And the number of cows be $y.$

So, total number of animals are:

$x+y=54$

$x=54-y$ ....( 1 )

As, the feet of cows are 4 and ducks are 2.

Now, the total number of feet are:

$2(x)+4(y)=122$

$2x+4y=122$

Substituting the value of $x$ from equation (1) we get:

$2(54-y)+4y=122$

$108-2y+4y=122$

$108+2y=122$

Subtracting both sides by 108 we get:

$2y=14$

Dividing both sides by 2 we get:

$y=7.$

The number of cows = 7.

Now, to get the number of ducks we substitute the value of $y$ in equation (1):

$x=54-y\\x=54-7\\x=47.$

The number of ducks = 47.

Therefore, he have 47 ducks and 7 cows.

the map shows Henry's town . Each unit represents 1 kilometer. After school, Henry walks to the library. How far does he walk?

ivann1987 [24]

Answer:

Henry walks 7 kilometres from school to library

Step-by-step explanation:

Given:

1 unit = 1 Kilometre

To Find:

The distance between the library and the school

Solution:

The map below shows that Henry has walked from

-2 coordinate in the x axis to coordinate 5 along the same x axis

So he has walked a total of 7 units

Since we know that 1 unit = 1 Kilometre,

7 units will be

=> 7 x 1

=> 7 Kilometres

I dont know how to do it like how to graph the -x or the y

geniusboy [140]

Answer:

see explanation and attachment

Step-by-step explanation:

(1) y = -x + 2

so slope is -1 and y-intercept is (0,2)

(2) 2x - y = 7

y = 2x - 7

so slope is 2 and y-intercept is (0,-7)
