A couch and coffee table cost a total of $1017 . The cost of the couch is two times the cost of the coffee table. Find the cost of each item.
Answers
Answer:
The couch costs $678 and $339 for the coffee.
Step-by-step explanation:
In total you spent $1017 and it was used in 3 portions, 2 for the couch, and 1 for the coffee. First divide it and find out how much each portion costs. In this case (1017 divided by 3) the answer will be 339. Now since you spent 2 of the 3 portions on the couch multiply one portion by 2. Then you get 678 for 2 portions, hence telling us that the couch costed, $678. With the remaining one portion of 339, you already know coffee costs $339.

find the value of Y! please help
Answers
Answer:
y = 5.6
Step-by-step explanation:
Use Sine
Sine = [tex]\frac{opposite}{hypothenuse}[/tex]
Sine 45 = [tex]\frac{y}{18}[/tex]
Sine of 18 is 0.309
0.309 = [tex]\frac{y}{18}[/tex]
Multiply 18 on both sides
0.309 x 18 = [tex]\frac{y}{18}[/tex] x 18
5.562 = y
Round to the nearest tenth:
5.562 = 5.6

whats the equation y= -3x + 6 in standard form
Answers
We know that the standard form of the equation is:
ax + by = c
and we are given the equation:
y = -3x + 6
Converting to standard form:
3x + y = 6 [adding 3x on both sides]
3x + y = 6

The three sides of AXYZ
measure 13 feet, 17 feet, and
21 feet. IS AXYZ an acute,
right, or obtuse triangle?
Answers
9514 1404 393
Answer:
acute
Step-by-step explanation:
I like to think of this in terms of the "form factor" (a term I made up). It is computed as ...
f = a² +b² -c²
where a, b, c are the side lengths, and c is the longest.
The interpretation is ...
f > 0 . . . acute
f = 0 . . . right
f < 0 . . . obtuse
Here, we have ...
f = 13² +17² -21² = 17 . . . . . the triangle is acute
_____
Additional comment
The measure of the largest angle is ...
arccos(f/(2ab)) = (17/(2(13·17)) = arccos(1/26) ≈ 87.8°
You can see that (2ab) is always positive, so the sign of f matches the sign of the cosine of the angle. That is what leads to the above interpretation.
This formula comes from the Law of Cosines, of which the Pythagorean theorem is a special case.

The boat is x=376 foot away from the light house.
A person is watching a boat from the top of a lighthouse. The angle of depression from the person to the boat is 28°. The lighthouse is 200 feet tall.
Trigonometry is defined as the study of angles.
Let the boat is x distance away from the lighthouse
assume a right-angle triangle ABC with AB =perpendicular=200, BC = base=X, Angle CAB = 28°(angle of depression means the angle from the boat to the top of lighthouse is also 28°)
tan28 = 200/X
X = 200/tan28
X = 376 foots
Thus, The boat is x=376 foot away from the lighthouse.

A helicopter hovers 500 feet above a small island. The figure shows that the angle of
depression from the helicopter
to point P is 49º. How far off
the coast, to the nearest foot, is the island?
Answers
Answer:
435 ft
Step-by-step explanation:
Reference angle = <P = 49° (angle of elevation)
Opposite side = 500 ft
Adjacent side = d = ?
Apply trigonometric function, TOA.
This:
Tan P = opp/adj
Tan 49 = 500/d
d × Tan 49 = 500
d = 500/Tan 49
d = 434.643369 ≈ 435 ft (to the nearest foot)

the clock was exactly on time at 7am at 1pm the clock was 228 seconds late at that rate how slow was the clock half an hour
Answers
Answer:
19 seconds.
Step-by-step explanation:
Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:
1 PM = 13:00
13 - 7 = 6
228/6 = 38
38/2 = 19
Thus, every half hour the clock is delayed 19 seconds.
