Answer:
Step-by-step explanation:
We have been given that in the after school Dena, Shawn, and Amanda knit scarfs that are the same size with yellow, white, and blue yarn. Denas scarf is 2/5 yellow, Shawn's scarf is 3/5 , and Amanda's scarf is 3/4 yellow.
To make Amanda's argument true, let us compare each fraction by making a common denominator.
We can see that least common denominator of each fraction would be 20.
Since , therefore, Amanda's scarf has the most yellow.
Answer:
B) BC'= 8, m A'= 28°
Step-by-step explanation:
When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.
To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':
- BC' = BC×1/2
- BC' = 16×1/2
- BC' = 8
The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.
Answer:
x = 4
Step-by-step explanation:
We assume your equation is intended to be ...
2^(2x+7) = 2^15
Equating exponents gives ...
2x +7 = 15
2x = 8 . . . . . . subtract 7
x = 4 . . . . . . . divide by 2
The value of x is 4.
