D.4 square root over 5
Answers
The number √80 in simplified radical form is 4√5. Therefore, the correct answer is option D.
The given number is √80.
Radical form is the expression that involves radical signs such as square root, cube root, etc instead of using exponents to describe the same entity.
Here, factors of number 80 are 2×2×2×2×5
= √16×5
= 4√5
Therefore, the correct answer is option D.

Answer:
The smaller number is 18
Step-by-step explanation:
Let the numbers be and
where x is the smaller number;
.
The sum of the numbers is 100.
The sum of 8 and the larger number is equal to 5 times the smaller number.
Put equation (2) into equation (1).
Answer:
The smaller number is 18.
Step-by-step explanation:
We have given that
The sum of two numbers is 100. The sum of 8 and the larger number is equal to 5 times the smaller number.
Let x and y are two numbers.
Let y is the larger number.
x+y = 100 eq(1)
y+8 = 5x eq(2)
From eq(1), we have
y = 100-x
Putting above eq(3) into eq(2), we have
100-x+8 = 5x
108 = 5x+x
108 = 6x
x = 108/6
x = 18
Hence, the smaller number is 18.

Answer:
The slope of X'Y' is m.
Step-by-step explanation:
It is given that XY is dilated by a scale factor of 1.3 with the origin as the center of dilation to create the image X'Y'.
Let the slope and length of XY are m and l respectively.
The dilation shows the enlargement and comparison of the figure. If the scale factor is more than 1 , then it shows enlargement. If the scale factor is more than 0 but less than 1 , then it shows compression.
The corresponding sides of image and preimage are parallel to each other. Since the slope of parallel line are equal therefore the slope of XY and X'Y' are equal, i.e., m.
The length of the image is k times of the length of preimage. The length of X'Y' is
Therefore the slope of X'Y' is m.

DAB and BCD are opposite angles on a parallelogram, which makes that they are alternate interior angles when looking at it from a perspective of 2 parallel intersected lines. This means that DAB will have the same value as BCD, therefore BCD = 115 degrees
