Answer:
Step-by-step explanation:
250 divided by 20= 12.5
So 12.5 miles per gallon.
Answer:
f''(2) = 8
Step-by-step explanation:
f'(x)= 2x³ - 4x +3
f''(x)= 2*3x - 4= 6x - 4
f''(2)= 6*2 - 4 = 12 - 4 = 8

Answer:
a) ∆RLG ~ ∆NCP; SF: 3/2 (smaller to larger)
b) no; different angles
Step-by-step explanation:
a) The triangles will be similar if their angles are congruent. The scale factor will be the ratio of any side to its corresponding side.
The third angle in ∆RLG is 180° -79° -67° = 34°. So, the two angles 34° and 67° in ∆RLG match the corresponding angles in ∆NCP. The triangles are similar by the AA postulate.
Working clockwise around each figure, the sequence of angles from lower left is 34°, 79°, 67°. So, we can write the similarity statement by naming the vertices in the same order: ∆RLG ~ ∆NCP.
The scale factor relating the second triangle to the first is ...
NC/RL = 45/30 = 3/2
__
b) In order for the angles of one triangle to be congruent to the angles of the other triangle, at least one member of a list of two of the angles must match for the two triangles. Neither of the numbers 57°, 85° match either of the numbers 38°, 54°, so we know the two triangles have different angle measures. They cannot be similar.
Answer:
8
Step-by-step explanation:
I am not sure if that is correct but....
40/5=8
Step-by-step proving:
8*4=32
40-32=8

Answer:
61.5
Step-by-step explanation:
PEMDAS
Parentheses
Exponents
Multiplication and Division
Addition and Subtraction
There is a Parentheses so we do it first:
6.5 times 4 is 26
We don't have any exponents so it is multiplication next since we don't have any division
26 times 2.25
58.5+5-2
We go from left to right
58.5+5 is 63.5
63.5-2 is 61.5
Thus the answer is 61.5
Hope this helps!
