Answer:
86%
Step-by-step explanation:
A percentage is a number or a ratio expressed as a fraction over 100. For example, 50% in fraction form is known as 50/100. 45% is known as 45/100.
Lets say the fraction was 43/50. We already know that a percentage is a number expressed as a fraction over 100, in order to convert this fraction into a percentage, we would have to multiply the denominator by a certain number in order to make it 100.
43/50 = x/100
If we multiply 50 × 2 = 100, so now we have to do the same for the numerator, and also multiply it by 2.
43 × 2 = 86
50 × 2 = 100
Now we know that the fraction is 86/100, now in order to convert it into percantage form, it would just be 86%

Answer: Surface area = 46 units²
Step-by-step explanation:
The formula for determining the total surface area of a rectangular prism is expressed as
Surface area = 2LW + 2LH + 2WH
Where
L represents the length of the rectangular prism.
W represents the width of the rectangular prism.
H represents the height of the rectangular prism.
Looking at the diagram,
L = 4 units
W = 2.5 units
H = 2 units
Therefore,
Surface area = (2 × 4 × 2.5) + (2 × 4 × 2) + (2 × 2.5 × 2)
= 20 + 16 + 10
= 46 units²
Two triangles are said to be congruent when the have the same sides and the same angles. When a figure is dilated by a value, the size of that figure changes.
Therefore, when Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle MꞌꞌNꞌꞌOꞌꞌ, the two triangles are similar but not congruent.
Answer: Equilateral triangles are also right triangles sometimes. All angles of an equilateral are congruet sometimes.
