Answer:
x ≈ 83.7
Step-by-step explanation:
You are given a right triangle with the hypotenuse, an acute angle, and the side adjacent to the angle marked. The hypotenuse is unknown. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
Filling in the given information, we have ...
cos(48°) = 56/x
x = 56/cos(48°) . . . . . multiply by x/cos(48°)
x ≈ 83.7
Answer:
Always
Step-by-step explanation:
In order for an integer to be even, one of the factors must be 2. Otherwise, it is odd.
If A is an odd number, it does not have a factor of 2.
If B is an odd number, it also does not have a factor of 2.
Therefore, AB also does not have a factor of 2, so it is always odd.
Answer:
x-intercepts = (-3/4, 0)
y-intercepts = (0, 3/7)
Step-by-step explanation:
Answer:
$8.33 per hour
Step-by-step explanation:
4(8.25) = $33 earned at the sporting goods store
2(10) = $20 earned shoveling snow
$53 = total earned in 6 hr.
53/6 = $8.33 per hour to nearest penny
$53/6 = exact amount earned per hour
Answer:
11. (x-2)/(x+8)
12. 9+t
13. h = 2A/b
Step-by-step explanation:
11. Since x is used to represent the number, 2 less than a number is x-2. 8 more than a number is x+8. The quotient of the first and second of these is the first one divided by the second one:
... (x -2)/(x +8) . . . . . parentheses are required unless the expression is typeset:
12. Apparently, we're to assume the salesman keeps on driving. If he had any sense (or a good union), he would stop after 9 hours. t hours added to 9 is ...
... 9 + t
13. Divide by the coefficient of h.
... h = A/((1/2)b) = 2A/b
