When two figures are similar the ratios of the lenghts of their corresponding sides are equal
Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 32² = 48²
x² + 1024 = 2304 ( subtract 1024 from both sides )
x² = 1280 ( take the square root of both sides )
x =

Answer: 16
Step-by-step explanation: you need an improper fraction. Do 6-2. Now, a/4=4. 16/4 equals 4. Therefore, a= 16.
Answer:
2) the graph has a positive slope. the slope is 15. the y-intercept is 50.
3) (4,110)
If you subtract the value of the extra dimes and pennies, you have groups of coins consisting of 1 dime, 1 nickel, and 1 penny, worth 16¢. The value of this reduced collection is $6.43 -0.35 = $6.08. That is the value of
.. 6.08/.16 = 38 . . . . groups of coins.
There were 38 +3 = 41 dimes in the box.
