The smallest of the four numbers is x.
Since the four numbers are consecutive, this means that each number is one more than the previous.
Therefore, the four numbers are:
x
x + 1
x+1 + 1 = x+2
x+2 + 1 = x+3
Now, we are given that the sum (s) of the four numbers is 2174
This means that:
s = x+x+1+x+2+x+3
s = 4x + 6
We are given that s = 2174. Substitute with s in the above equation and solve for x as follows:
2174 = 4x + 6
4x = 2174 - 6
4x = 2168
x = 2168 / 4
x = 542
Based on the above calculations, the four numbers are:
542, 543, 544 and 555
The given shapes area is found to be 132 square feet.
Step-by-step explanation:
Step 1; To determine the area of an indefinite shape we must divide it into the shapes that we know. The shape that is given can be split into a rectangle with a triangle on top of it.
Step 2; To determine the area occupied by a different shape, we must sum the areas of the triangle and the rectangle. The given rectangle measures a length of 11 feet and a width of 9 feet. The area of any given rectangle is the multiplication of its length and width. Area of Rectangle = Length * Width = 11 feet * 9 feet = 99 square feet.
Any given triangles area is half the multiplication of its base value and its height value. In the given diagram, the base of the triangle measures a length of 11 feet (same as the rectangle's length) and the length from base to top is 6 feet (Entire shape's height which is 15 feet - the calculated value of the rectangle's width which is 9).
Area of Triangle = * base * height = * 11 feet * 6 feet = 33 square feet.
Step 3; To find the total area of the shape we must add the areas of the rectangle and the triangle.
Area of given shape = Area of rectangle + Area of Triangle
Area of given shape = 99 square feet + 33 square feet = 132 square feet.
If it takes .1 hours to walk 2/6 miles, then it takes one hour to walk 20/6 miles.
20/6 miles = 3.33 miles
So that is 3.33 miles per hour.
You would only haev to multiply it when you multiply 9 times 895 you would get 8055
Hope this helped
Answer:
Therefore,
Surface area of Red sphere is 2826 square in.
Step-by-step explanation:
Given:
Blue Sphere Radius=20 in
Red Sphere Radius=15 in
pi = 3.14 ( also you can take )
To Find:
the surface area 'S' of the red sphere = ?
Solution:
Surface area of sphere for radius 'r' is given as
Substituting the values we get
For Red Sphere,
Radius = 15 in
Therefore,
Surface area of Red sphere is 2826 square in.
Similarly, you can find for Blue Sphere also
Also you will have different value for
