1.The area of a square is 49in^2=.What is the perimeter of the square​

Mathematics

28 in. Because 7x7=49 (sides of a square are equal) so you know that each side is 7 in, now multiply by 4 (for the number of sides) to find the perimeter.

Please help me in the question of commission ! Grade - 9 . ​
AlladinOne [14]

Answer:

Step-by-step explanation:

Commission for  amount  Rs. 5,00,00 = \frac{2}{100}*500000

                                                               = 2* 5000

                                                               = Rs. 10,000

total commission = Rs. 32,000

Remaining commission = 32500 - 10000

                                      = Rs. 22500

Let remaining amount of the restaurant = Rs. x

Commission on Rs. x = 22500

3% of x = 22500

\frac{3}{100}*x=22500\\\\x=22500*\frac{100}{3}\\\\x = 7500*100

x = Rs. 750000

Price of the restaurant = 750000 + 500000

                                     =Rs . 1250000

Use the distance formula d = rt to find the unknown value d = 405 mi t = 7.5 h
DochEvi [55]

Answer:

r = 54 miles per hour

Step-by-step explanation:

Since we have been given the values for two of the unknowns, we can substitute them into the equation to find the third.

d = 405

t = 7.5

d = rt

405 = r (7.5)

405=7.5r

Now to find r, we need to get it by itself on one side so we have r = ...

We can do this by dividing 7.5 from both sides of the equation as this will cancel out the 7.5, leaving us with the r value, and everything you do to one side of an equation must also be done to the other side.

405/7.5=7.5r/7.5

54=r

The unknown value 'r' = 54

Since 'r' stands for 'rate', the units given must be appropriate for speed. As the distance was given in miles, and the time in hours, the unit for 'r' must be miles/hour. Therefore r=54miles/hour.

Hope this helped!

Help please, finals week is upon me​
kenny6666 [7]

The circumcenter is found by finding the intersection of at least 2 perpendicular bisector segments.

Find the perpendicular bisector to segment AB. This is the line y = -3.5; the idea is that you find the equation of the horizontal line through the midpoint of AB. The midpoint has a y coordinate of -3.5. This line is shown in red horizontal line in the attached image below.

The midpoint of AC is 2.5, so the perpendicular bisector to AC is x = 2.5 which is shown as the vertical green line in the same diagram.

The red and green lines cross at the location (2.5, -3.5) which is the circumcenter's location. If you were to draw a circle through all three points A, B, & C, then this circle would be centered at (2.5, -3.5)

If point D is the circumcenter, then we know this

AD = BD = CD

basically the distance from the center to any point on the triangle is the same. This is due to the fact that all radii of the same circle are the same length.

<h3>Answer: (2.5, -3.5)</h3>

note: 2.5 in fraction form is 5/2 while -3.5 in fraction form is -7/2
