The building is about 70.95 feet tall.

The building and the laser range will form a right triangle. You can use the Pythagorean Theorem to find the height of the building.

112^2 + b^2 = 131^2
b = 67.95

However, don't forget to add on 3 because that is the height of the laser range.

A water tank holds 666 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 888 gallons but is leak
Katen [24]

Answer:

74 weeks

Step-by-step explanation:

Given :

Let x = number of weeks

Gallon A:

Capacity = 666

Leak rate = 4 gallons per week

666 - 4x

Gallon B:

Capacity = 888

Leak rate = 7 gallons per week

888 - 7x

666- 4x = 888 - 7x

666 - 888 = - 7x + 4x

-222 = - 3x

x = 222 / 3

x = 74

After 74 weeks

Quadrilateral ABCD is reflected across the x-axis and then reflect across the y-axis to form quadrilateral A?B?C?D?. If the coor
Dmitriy789 [7]

Answer:

A'(7,-3)

Step-by-step explanation:

We were given the coordinates, A(-7,3) of quadrilateral ABCD and we want to find the image of A after a reflection across the x-axis followed by a reflection in the y-axis.

When we reflect A(-7,3) across the x-axis we negate the y-coordinate to obtain: (-7,-3).

When the image is again reflected in the across the y-axis, we negate the x-coordinate to get (--7,-3).

Therefore the coordinates of A' after the composed transformation is (7,-3).
