If the pattern (see attachment) below was tripled, the ratio of black squares to gray squares would be equal to 1:2.
<h3>What is a proportion?</h3>
A proportion can be defined as an equation which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.
Mathematically, a direct proportion can be represented by the following equation:
y = kx
Where:
- y and x are the variables.
- k represents the constant of proportionality.
<h3>What is a ratio?</h3>
A ratio can be defined as a mathematical expression that's used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.
For this exercise, the ratio of black square to gray squares is given by:
B:G = 1:2
Tripling the pattern, we would multiply by three (3) as follows:
B:G = [1:2] × 3
B:G = 3:6
Dividing all through by 3, we have:
B:G = [3:6]/3
B:G = 3/3 : 6/3
B:G = 1:2.

Answer:
So the superhero covers 2450 miles in 30 minutes or 1/2 hour
Thus, he/she will cover (2450 x 2) miles in 1 hour
Therefore the answer is his/her velocity is (2450 x 2) miles/hour = 4900 miles/hour.
Hope this helps!

Answer:
(d) Isosceles right
Step-by-step explanation:
You want to know the classification of a triangle with angles 45°-45°-90°.
<h3>Classification</h3>
The largest angle is 90°, a right angle. Any triangle containing a right angle is a <em>right triangle</em>.
Two of the angles have the same measure. This means the triangle is an isosceles triangle.
The triangle is classified as an isosceles right triangle.
__
<em>Additional comment</em>
A triangle whose largest angle is less than 90° is an <em>acute</em> triangle. If the largest angle is greater than 90°, it is an <em>obtuse </em>triangle.
If no sides are the same length, the triangle is <em>scalene</em>. If two sides are the same length, the triangle is <em>isosceles</em>. If all three sides are the same length, it is an <em>equilateral</em> triangle.
Larger angles are opposite longer sides, so if angles are the same, their opposite sides are the same.
It can be worthwhile to remember that the side length ratios in an isosceles right triangle are 1 : 1 : √2.
Answer:
i can't solve it because it's not complete
you need something 2^2 (right here) -^1=8^x-1
