Answer:
For the value of will be the same of .
Step-by-step explanation:
To determine for which value of , we need to apply the following identity () and solve numerically the resulting expression:
(1)
A quick approach is using graphic tool and looking for the value of such that . The result of the analysis is included below in the attached image. We find the following result:
For the value of will be the same of .
Answer:
D. 36 units
Step-by-step explanation:
The description of the triangle is:
<em>triangle XYW in which angle W is a right angle, angle X measure f degrees, and angle Y measures d degrees
</em>
Therefore, side XY is adjacent to f and side XY is the hypotenuse
From definition:
cos(f) = adjacent/hypotenuse
Replacing:
cos(f) = XW/XY
4/9 = 16/XY
XY = 16*9/4
XY = 36 units
Joey has an average of 8. While Carlos has an average of 7.125. Joey has the greater average by 0.875
13.53 kg
1000 g in a kg
13530 ÷ 1000 = 13.53 kg
Answer:
Step-by-step explanation:
Let q represent the number of quarters. Then Tony's coin value is ...
0.25q +0.10(25 -q) = 4.00
0.15q +2.50 = 4.00 . . . . . . . . eliminate parentheses, collect terms
0.15q = 1.50 . . . . . . . . . . . . . . subtract 2.50
q = 10 . . . . . . . . . . . . . . . . . . . . divide by the coefficient of q
Then the number of dimes is ...
25 -10 = 15
Tony has 15 dimes and 10 quarters.
