The perimeter of the square

Mathematics
1 answer:
Rama09 [41]3 years ago
4 0

Answer:

x = 20/49 units; P = 8 48/49 units

Step-by-step explanation:

All sides of a square are congruent.

That means that the two given side lengths are equal.

We set the two lengths equal and solve the equation for x.

5.5x = (1/5)(3x + 10)

Multiply both sides by 5.

27.5x = 3x + 10

Subtract 3x from both sides.

24.5x = 10

x = 10/24.5

x = 20/49

The perimeter of a square is 4s, where s is the length of a side.

P = 4s

= 4(5.5x)

= 4 * 5.5 * 20/49

= 22 * 20/49

= 440/49

= 8 48/49

Answer: x = 20/49 units; P = 8 48/49 units

Please please please help me with this. I can't remember how to work this problem out. If someone could explain to me how to do

If the two triangles are congruent it means that their side lengths are equal, so we can assume that x = 3x - 8 and so 2x = 8 and x = 4. Hope that helps :)

) How many kilowatt hours would the model predict on a day that has 14 hours of possible daylight?
eimsori [14]

Question:

A solar power company is trying to correlate the total possible hours of daylight (simply the time from sunrise to sunset) on a given day to the production from solar panels on a residential unit. They created a scatter plot for one such unit over the span of five months. The scatter plot is shown below. The equation line of best fit for this bivariate data set was: y = 2.26x + 20.01

How many kilowatt hours would the model predict on a day that has 14 hours of possible daylight?

Answer:

51.65 kilowatt hours

Step-by-step explanation:

We are given the equation line of best fit for this data as:

y = 2.26x + 20.01

On a day that has 14 hours of possible daylight, the model prediction will be calculated as follow:

Let x = 14 in the equation.

Therefore,

y = 2.26x + 20.01

y = 2.26(14) + 20.01

y = 31.64 + 20.01

y = 51.65

On a day that has 14 hours of daylight, the model would predict 51.65 kilowatt hours
