Step-by-step explanation:
Given
The ratio of two similar figures is 169:289
Suppose, their length ratio is x:y
Similarly, cube of the ratio is equal to the volume ratio
Thus, the volume of the larger solid is
The perimeter represents the amount of wood needed and the area represents the amount of class needed.
so 2*(2/3) + 2(2) = 4/3 + 4= 4 4/3 or 5 1/3 wood is needed for the border.
for the mirror, you will need the area= 4/3 * 2 = 8/3 sq yds or 2 2/3 sq yards is needed.
Answer:
x = 6
Step-by-step explanation:
180° is always all triangles.
This is a right triangle, so that means that the angle that is unknown is 90.
Angles:
90
60
7x - 12
90 + 60 + 7x - 12 = 180
150 - 12 + 7x = 180
138 + 7x = 180
7x = 180 - 138
7x = 42
7x/7 = 42/7
x = 6
Answer: 1.5
Step-by-step explanation: To find 5% of 30, first write 5% as a decimal by moving the decimal point 2 places to the right to get <em>.</em>05.
Next, the word "of" means multiply, so we have (.05)(30) which is 1<em>.</em>5.
So 5% of 30 is 1<em>.</em>5.
