Answer:
[tex]x = 56[/tex]
Step-by-step explanation:
Use tangent function.
[tex] \tan(x) = \frac{18}{12} [/tex]
Take the arctan
[tex] \tan {}^{ - 1} ( \frac{18}{12} ) [/tex]
which is about
0.98279372.
Convert from radians to degrees in you will get
56 degrees.
Answer:
Step-by-step explanation:
You can solve this by using trigonometry and the formula SOH CAH TOA. You're looking for an angle that is adjacent (next to) 12, and opposite 18. Therefore, you will needed to use TOA, which stands for tangent = opposite/adjacent.
With substitution, this gives you tangent = 18/12. 18/12 is equal to 1.5. Because we are looking for an angle we need to use the tan^-1 (tan to the power of -1) button on our calculator. Tan(1.5)^-1 equals 56.31 to 2dp.
Hope this helps!

Answer:
30 ft², 40 ft², 70 ft²
Answer:
4th option
Step-by-step explanation:
Applying Pythagoras' identity to the figure
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, then
If the area on the 2sides is 30 ft² and 40 ft² then the hypotenuse is
30 ft² + 40 ft² = 70 ft²

Step-by-step explanation:
If you multiply 3 by 5, you have the answer of 15.
Or
X / 3 = 5
Multiply both sides by 3 to clear the fraction.

25% of what number is 8?
Answer:
32
Step-by-step explanation:
25% of 32 is 8. 100% of 32 is 32, therefore 25 percent of 32 equals 8.
If you know the length of the side of the square, how can you figure out the area?

Answer:
326.6 square inches3402 square feetStep-by-step explanation:
The net will be a rectangle representing the lateral area. Its length will be 2π(4 in), the circumference of the box, and its height will be 9 in, the height of the box. On either side of that rectangle will be an 8-in diameter circle representing the ends of the box.
The total surface area is given by the formula ...
SA = 2πr(r +h)
For one box, the area is ...
SA = 2(3.14)(4 in)(4 in +9 in) ≈ 326.6 in² . . . . area of one box
__
There are 144 square inches in a square foot, so the area required for 1500 boxes is ...
(1500)(326.56 in²)/(144 in²/ft²) ≈ 3402 ft² . . . area of 1500 boxes
Help me please <3 .....
Answer:
For sure the third one. I think the 1st one too.
Happy learning!
Answer:
The first and the third one. The second and the fourth one are incorrect because y is increasing fast while x is increasing slowly. I know this because the graph is steeper. If we assume that the x-axis represents time then more is being done in less time and that is not proportional. In a proportional graph, as x will increase a little bit, so will y. Hope this helps :)

Special Right Triangles (Radical Answers)
Answer:
x = [tex]5\sqrt{2}[/tex]
Step-by-step explanation:
We know that;
The triangle is isosceles, and the hypotenuse is x, the un-labeled side is 5.
Therefore we can say;
5² + 5² = x²
25 + 25 = x²
50 = x²
[tex]\sqrt{50}[/tex] = x
We can simplify this further;
[tex]\sqrt{25} * \sqrt{2}[/tex] = [tex]\sqrt{50}[/tex]
[tex]5\sqrt{2}[/tex] = [tex]\sqrt{50}[/tex]
Hope this helps!
Pls help I will give crown
Answer:
35 yards
Step-by-step explanation:
The formula for an area of a trapezium or trapezoid is h(a+b)/2. H is the height, and a and b are the the two opposite sides. With substitution, we get 5(6+8)2 = 70/2 = 35
Answer:
35 yd²
Step-by-step explanation:
First, you need to find the remaining side:
You need to find the bottom side of the triangle: 8-6=2 yd
Let's calculate the area of the triangle:
[tex]\frac{5*2}{2} =5[/tex] yd²
Let's calculate the area of the rectangle:
6*5 = 30 yd²
Total area: 30+5 = 35 yd²
What are the center and the radius of the circle whose equation is (x-5)^2+(y+3)^2=16
CENTER : ( 5, -3)
RADIUS : 4
Answer:
Center (5,-3)
radius : 4
Step-by-step explanation:
Radius: is the square root of 16. The square root of 16 = +/- 4. Minus 4 has absolutely no meaning for a question like this so the radius is 4. Rule take the square root of the counting number on the right.
The center is the value when x - 5 =0 and y + 3 = 0
x - 5 = 0
x = 5
y + 3 = 0
y = -3

Answers:
[tex]x = 5\sqrt{3}[/tex]
[tex]y = 10[/tex]
==================================================
Explanation:
This is a 30-60-90 triangle. The short leg 5 is opposite the smallest angle 30 degrees.
The long leg is sqrt(3) times that of the short leg, which explains why x = 5*sqrt(3).
The hypotenuse is twice as long compared the short leg, so y = 2*5 = 10.
You could use trig ratios and the unit circle as another way to find x and y.

Answer:
E) 25.5 units²
Step-by-step explanation:
The figure is not carefully drawn, so it is difficult to tell that it is a trapezoid. The "height" of it is BC, the diagonal of a rectangle that is 1 unit by 4 units. The Pythagorean theorem tells you that length is ...
BC = √(1² +4²) = √17
We notice that the "bases" of the trapezoid (CD and AB) are 1 and 2 times this length. The trapezoid area formula tells us the area is ...
A = 1/2(b1 +b2)h
A = 1/2((√17)(1 +2))(√17) = 3/2(17) = 25.5 . . . . square units
_____
Alternate solution
Pick's Theorem is a theorem that can help you find the area of a polygon when its vertices are all on grid points. It tells you the area is ...
A = i + b/2 -1
where i is the number of grid points interior to the figure, and b is the number of grid points on the boundary. Here, the boundary grid points are those that are labeled plus the one at (-2, 1). Counting the interior grid points gives a total of 24, so the area by Pick's theorem is ...
A = 24 + 5/2 -1 = 25.5 . . . square units
__
Additional comment
Once you're familiar with Pick's theorem (and/or any of a few other methods of computing area from coordinates), you see that the area of any polygon whose vertices are grid points will be an integer multiple of 1/2. The only such answer choice here is choice E.
Tamsen pays $12.50 of her monthly life insurance premium, and her
employer covers the rest. If her monthly premium is $42.25, what is the
annual value to Tamsen of this benefit?
A. $150
B. $357
C. $507
D. $328.50
Benefit she gets monthly is = 42.25-12.5= 29.75
annual value to Tamsen of this benefit= 12×29.75 = 357$
why in math, whenever you do an explanation, for example, 2x - 20, the subtraction sign make the 20 a negative number?
Answer:
The negative sign is put before numbers to make them negative, or make their signs the opposite of what the are.
You have a 20.
+ 20
You don't need to put the + there if there is nothing before it, but that is a positive 20.
If you put a negative in front of it;
- (+ 20) = - 20
If you have a negative in front of parenthesis;
50 - (2x - 20)
50 - 2x + 20
70 - 2x

Drag and drop each choice into the correct boxes to complete the description of how to find the sums -2 + 1 and -2 + (-1) on a number line
Answer:
a. -1
b. -3
Explanation:
To solve negative and positive numbers on the number line, we make a simple analogy. If we wanted to -3+2 for instance:
Imagine a customer placed an order for 3 bags of apples from your store but you are out of stock and only have 2 bags left. You then come to an agreement with the customer to send 2 bags now and send the remaining one later in the week when your stock arrives from your supplier. In this way, you are only able to send two bags which you have,+2, and then be owing the customer one bag left(-1) to deliver out of the three, -3.
To solve -2+1 on the number line, with -2 on the left side of 0(negative) on the number line and +1 on the right side of 0(positive), we use same analogy above.
-2+1= -1
Also using same analogy, -2+(-1)= -3
Note: +1×-1=-1

Answer:
x=√30
Step-by-step explanation:
Because the triangle is equilateral and is cut by the bisector, both triangles are 30-60-90 triangles. Therefore, to find side x, you multiply the short side by √3. This means that side x is √10*√3=√30 units.
