Answer:
Step-by-step explanation:
1° = π /180° radians
390° = 390* π / 180 radians; simplify
39*π / 18 = 13 π/ 6 ≈ 6. 81 radiants
Answer:
$68.25
Step-by-step explanation:
1. First, to find the cost of one sweatshirt, we multiply 175 by 13, and then divide by 100.
2. Now, we know that one sweatshirt costs $22.75. To find the cost of three sweatshirts, we multiply 22.75 by 3.
Therefore, the cost of 3 sweatshirts is $68.25.
Answer:
(x-5) (x-2)
Step-by-step explanation:
x^2 (-2x-5x) +10
basically you will write the equation down and then to double check multiply the x and then the -5 into (x-2). this can be repetitive if you get it wrong so try to do numbers that make sense.

slope as you should already know is rise/run, or how much something moves in relation something else, namely how much the y-axis go up as the x-axis moves sideways, one moves, the other follows, but the increments will be different, sometimes the same, but usually different.
the y-intercept means, when the graph of the equation touches or intercepts the y-axis, and when that happens x = 0, or the horizontal distance is at bay.
for the slope on 6), 30 or 30/1 means, for every 1 year(x) passed, the worth(y) increased by 30, or jumped by 30 units, so as the x-axis moved 1, the y-axis moved 30. After 12 years 30 * 12 = 360, and we add the initial 720 and we end up with 1080.
the y-intercept, well, as aforementioned is when x = 0, is year 0.
Answer:
∠F = 42°
Step-by-step explanation:
similar triangles have congruent corresponding angle measures.
so if ΔABC ~ ΔEFG, then ∠B corresponds with ∠F, so ∠F = ∠B
∠F = 42°
