Step-by-step explanation:
The ratio of the two shorter legs of the top triangle is
The bottom triangle has the following ratio:
Since their ratios are the same, this means that the two triangles are similar.
Answer:
A. 8 students
B. Because 24% of 24 is 5.76
Step-by-step explanation:
A: The ratio of students is 2:5, that means for every 7 students from her class, 2 of them are in the show.
28/7 is 4, so there are 2(4) = 8 students in the talent show.
B: 24(24%) = 24(0.24) = 5.76. The question says 'exactly' 24%. We can't have 0.76 of a person, so we can't have 'exactly' 24%
Here, we are to find the length and the breadth of the rectangle
Length of the rectangle = 7 units and Breadth of the rectangle = 3 units
Let
length = l units
Breadth = b units
Perimeter of the rectangle = 20 units
length is the distance measured along the longest dimension of an object
width is the wideness of an object
perimeter refers to the total measurements of an objects
The breadth of a rectangle is 4 units less than its length
If,
Length = l
Then,
b = l - 4
Perimeter of a rectangle = 2(length + breadth)
20 = 2{l + (l - 4)
20 = 2(l + l - 4)
20 = 2(2l - 4)
20 = 4l - 8
20 + 8 = 4l
28 = 4l
l = 28/4
l = 7
b = l - 4
b = 7 - 4
b = 3 units

The answer to your question is x = 8
Answer:
Step-by-step explanation: We have been given 4 expressions. We are asked to choose the expression that represents sum of cubes.
We know that sum of cubes is in form .
We can see that 1st and 2nd option has a negative sign. Therefore, these options cannot be sum of cubes.
Let us check 3rd and 4th options one by one.
We can rewrite our expression by writing terms as cubes:
Therefore, expression is a sum of cubes.
In 4th expression, we can see that . We cannot represent it as a cube. Similarly, we cannot represent as a cube. Therefore, 4th expression is not correct.
