Answer:
She drove 3 hours
Step-by-step explanation:
Leslie drove 2/3 of the 4 1/2 hours trip. To determine how long she drove, multiply these numbers together.
2/3 * 4 1/2
We need to change the second number to an improper fraction
4 1/2 = (2*4 +1)/2 = 9/2
2/3 * 9/2 = 9/3 = 3
She drove 3 hours
Answer: x = 5
You can pick any number you want, as long as it's not zero. The equation x = 5 has all points on this line that have an x coordinate of 5. The y coordinate can be anything you want
Example points on this line are: (5,1) and (5,2)
Note: this is a vertical line with the slope undefined. There is no y intercept. This is not a function because it fails the vertical line test.
is 4 inches. Determine the slant height of the
pyramid.
Answer:
Step-by-step explanation:
Let h be the slant height of the square pyramid.
Given:
Total surface area of the square pyramid = 40 square inches
And square base has a side length = 4 inches
We need to find slant height of the square pyramid.
The surface area of the pyramid is sum of the area of the square and area of each of the triangle faces.
-------(1)
The base area of the square pyramid =
So,
And area of the triangle =
Where b = base of the triangle
The base of the triangle is one side of the square pyramid base, so the base of the triangle is 4 inches.
And h = slant height of the triangle.
So the area of the triangle = 2h square inches
Now we substitute area of the base and area of the triangle in equation 1.
Now we substitute the value of total surface area of the square pyramid in above equation.
Simplify the above equation.
Therefore the slant height of the square pyramid is 3 inches.
Answer:
Step-by-step explanation:
1. 9 square inches
2. 60 square inches
3. 69 square inches
Given the dimensions of the brick, we first calculated its volume in cubic meters. Then we calculated the volume of the wall in cubic meters. Dividing the volume of the wall by the volume of a single brick, we find that we need 20,000 bricks to build the wall.
This is a problem in Mathematics, specifically involving volume and unit conversion. The volume of the brick can be calculated using the formula for the volume of a rectangular prism, Volume = length x width x height. The dimensions given for the brick are in centimeters and the wall dimensions are given in meters. Therefore, we must convert the brick dimensions to meters: 30 cm = 0.3 m, 10 cm = 0.1 m and 7.5 cm = 0.075 m. The volume of one brick is 0.3 m * 0.1 m * 0.075 m = 0.00225 cubic meters.
The volume of the wall is also given by the formula length x width x height, so it is 30 m * 2 m * 0.75 m = 45 cubic meters. To find the number of bricks required to fill this volume, divide the volume of the wall by the volume of a single brick, 45 m³ / 0.00225 m³ = 20000 bricks. Thus, it will take 20,000 bricks to build the wall.
