3 · 7.5 = 22.5:  22.5 is the area of the building on the blueprint in inches

22.5 · 10 = 225 feet squared is the area of the building in real life.

hope this helped!

At the bike shop x, it cost $2.75 per hour plus a $3.00 deposit to rent a bike.AT Bike shop z cost $1.75 per hour plus a $7.00 d
Alex_Xolod [135]

Multiply the rate per hour by the number of hours (n) and add the deposit.

A)

Bike shop x: c = 2.75n + 3.00

Bike shop z: c = 1.75n + 7.00

B) to find when they will cost the same set the equations equal to each other and solve for n:

2.75n + 3.00 = 1.75n + 7.00

Subtract 3 from each side:

2.75n = 1.75n + 4.00

Subtract 1.75n from both sides:

1.00n = 4.00

Divide both sides by 1:

n = 4 hours

If a point has a negative x-coordinate, and its y-coordinate is positive, where does the point lie relative to the origin? Expla
Daniel [21]
      If a coordinate has a negative x-coordinate and its y-coordinate is positive, then the point  is on the 2nd quadrant.
      That means that the point is left of the origin and above it.

Answer:

Both triangles are scalene & Both triangles have an obtuse angle.

Step-by-step explanation:

<u>Key skills needed: Triangle recognition, Comparing Triangles</u>

1) We are given those 2 triangles, and we need to see if they are isosceles, scalene, obtuse, and acute.

2) To get this, let's define each thing:

Acute triangle - Means that all the angles in triangle are acute, which means they are less than 90 degrees in measure.

Obtuse triangle - Means that one angle in the triangle is obtuse, which means it is greater than 90 degrees in measure.

Scalene triangle - All the sides of the triangle are different in size/length

Isosceles triangle - 2 sides of the triangle are the same length

3) Now, we can use this to see what both triangles are:

--> Both triangles are not isosceles, they are both scalene. This is because all the sides of each triangle are different in size/length. This makes it scalene.

--> Both triangles are not acute triangles, they are both obtuse triangles. This is since the largest angle in each triangle is clear an obtuse angle (it looks like it is more than 90 degrees). Refer to the image I post as help.

With the observations above: We can say that both triangles are scalene, and both triangles are obtuse triangles.

<em>Hope you understood and have a nice day!! :D</em>
