---------------------
For the 46° angle, h is the opposite leg. The hypotenuse is 10 ft. The sine is the trig ratio that relates the opposite leg to the hypotenuse.
sin A = opp/hyp
sin 46° = h/10
h = 10 sin 46°
h = 7.193

Answer:
x = ±√13x = ±3√6x = ±√66x = 0 or 8Step-by-step explanation:
As in any "solve for" situation, you "undo" what is done to the variable.
Here, (for 3 of the 4 problems) the variable is ...
squaredmultiplied by a constantadded to a constantWe undo these operations in reverse order. First, we add the opposite of the added constant. Then we divide by the coefficient of x². Finally, we take the square root to "undo" the squaring operation.
1. 4x² -30 = 22 . . . . . . given
4x² = 52 . . . . . . . . . add 30 to both sides
x² = 13 . . . . . . . . . . . divide both sides by 4
x = ±√13 . . . . . . . . . take the square root. Both signs are solutions.
__
2. 3x² +4 = 166 . . . . . given
3x² = 162 . . . . . . . . add -4 to both sides
x² = 54 . . . . . . . . . . divide both sides by 3
x = ±√54 . . . . . . . . take the square root. 54 = 3²·6 has a square factor
x = ±3√6 . . . . . . . simplified result
__
3. (1/3)x² +14 = 36 . . . . given
(1/3)x² = 22 . . . . . . . . add -14 to both sides
x² = 66 . . . . . . . . . . . multiply both sides by 3
x = ±√66 . . . . . . . . take the square root
__
4. The same "undo" idea applies. Here, we can start with the square root.
(x -4)² = 16 . . . . . given
x -4 = ±4 . . . . . . . square root
x = 4 ± 4 . . . . . . add 4 to both sides
This means x = 4-4 = 0, or x = 4+4 = 8.
The solutions are x = 0, x = 8.

600 raffle tickets were sold for $5 each. There is one $500 first prize and three $200 second prizes. The remainder of the tickets do not win anything. What is the expected value of this raffle?
Answer:
its -$3.17
Step-by-step explanation:
500-5=495
200-5=195
the remainder of the tickets is -$5
the expected value is $495 x 1/600 + $ 19583/600 + (-$5) 596/600= -$3.17

Kim sold christmas pies for 5.00$ each. She earned 156 how many pies she sold also let x repersent the number of pies, x, kim sold
Answer: 31.2 pies
Step-by-step explanation:
Kim sold pies for $5.00 each and earned $156 from doing so.
The number of pies she sold to get to this was x pies.
The formula for doing so is therefore:
5 * x pies = 156
5x = 156
x = 156 / 5
= 31.2 pies

the difference between two numbers is 14. if 1/3 of the larger number is subtracted from the smaller number ,the result equals 1/10 of their sum. find both numbers
Step by step please
Answer:
Step-by-step explanation:
x-y=14
x-1/3y=1/10
-y=14-x
y=-14+x
take out the factors
x-10/30y=3/30
30x-10y=3
substitute
30x-10(-14+x)=3
30x+140-10x=3-140
20x/20=-137/20
x=-6.85
y=-14+(-6.85)
y=-20.85
The two numbers are 143/20 and 423/20.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Given that, the difference between two numbers is 14.
Let the smaller number be x and the larger number be y.
Here, y-x=14 ------------(i)
If 1/3 of the larger number is subtracted from the smaller number ,the result equals 1/10.
1/3 of larger number is 1/3 y
x-y/3 =1/10 ------------(ii)
From equation (i), substitute y=14+x in equation (ii), we get
x-(14+x)/3 =1/10
10(3x-14-x)=3
30x-140-10=3
20x-140=3
20x=143
x=143/20
Substitute x=143/20 in equation (i), we get
y-143/20=14
y=14+143/20
y=(280+143)/20
y=423/20
Therefore, the two numbers are 143/20 and 423/20.

A. y=-3x+1
B. y--3x+3
C. y = 2 x -
D. y-22 8x-3
Answer:
y = -2/3x - 3

Write an inequality for the graph.
Answer:
h(x) ≥ |x - 5| +1
Step-by-step explanation:
Given graph represents an absolute function (parent function)
f(x) = |x|
Since, graph of the function 'f' has been shifted 5 units to the right new function will be,
g(x) = f(x - 5)
g(x) = |x - 5|
Again function 'g' is shifted 1 unit upwards along the y-axis then the new function will be,
h(x) = g(x) + 1
h(x) = |x - 5| + 1
There is a shaded region representing the solution area lying above the intersecting dark lines,
Therefore, solution region will be re[presented by the inequality,
h(x) ≥ |x - 5| + 1

The sum of the interior angles of a regular polygon is 3 times the sum of its exterior angles. Determine the number of sides of the polygon?
Answer:
Octagon
Step-by-step explanation:
Sum of interior angles = 3*360 = 1080
sum of interior angles, is also, s = (n-2)180
From that,
n-2)180 = 1080
n-2 = 1080/180
n = 6 + 2
n = 8
Therefore, the figure is an 8 sided polygon or an octagon
Answer:
number of sides of a polygon is 8(because the polygon is octagon)
sum of interior angle of a octagon=1080 degree
sum of exterior of a octagon = 360 degree
Step-by-step explanation:
here in question ,
interior angle of a polygon=3*360(exterior angle of a polygon is always 360 degree)
=1080

fence in eight hours. Find how long it
would take them if they worked together.
Answer:
it would be In 17 hours
Step-by-step explanation:
let me know if I am wrong or right thxs
Answer:
4 4/17 hours
Step-by-step explanation:
In one hour Jacob can paint 1/9 of the fence
In one hour Molly can paint 1/8 of the fence
This equation can determine how long it would take if they worked together:
1/9x + 1/8x = 1
multiply each term by lcm of 72 to eliminate denominators to get:
8x + 9x = 72
17x = 72
x = 72/17
x = 4 4/17 hours

The Barnes family has a coupon for 10% off their dinner. If their bill comes to $82.50 and they wish to tip 15%, what will they pay in total?
Answer:
Total cost= $86.25
Step-by-step explanation:
Giving the following information:
Discount= 10%
Nill= $82.5
Tip= 15%
First, we need to calculate the discounted price:
Discount price= 82.5 / 1.1= $75
Now, the tip:
Tip= 75*0.15= $11.25
Finally, the total cost:
Total cost= 75 + 11.25
Total cost= $86.25
