Answer:
15 gumballs
Step-by-step explanation:
There would have to be...
30%*50 green gumballs
We can start by converting 30% to a fraction. Any percentage is just that number over one hundred so...
30/100*50
We can simplify 30/100 by dividing the numerator and the denominator by 10...
3/10*50
Cancel out 10 and 50 (50/10=5)
3*5
15 gumballs would have to be green
The area of the trapezoid is (1/2)(4+14)(10) = (5)(18) = 90.
The area of the triangle is (1/2)(14)(8) = 56.
Adding these, we get 56 + 90 = 146.

Answer:
Step-by-step explanation:
The sign of a product or quotient cannot be determined by the positive number (t), so we can ignore it. The sign of the expression will be negative if and only if there are an odd number of negative factors.
Here, there are 67 (an odd number) negative factors, so the expression will be negative.
Answer:
A dilation preserves angle measures.
A dilation alters the length of line segments by the same proportion.
Step-by-step explanation:
A dilatation is a transformation that alters a figure's size while maintaining its shape and orientation. Each linear measure of the figure, such as a side length, is multiplied by the scale factor of a dilatation. A dilation is a transformation where all line segments' lengths are altered uniformly. While a dilatation can alter a figure's size, it cannot alter a figure's form. Dilations are not isometries as the figure's size changes.
