Step-by-step explanation:
[tex] \tan(45) = \frac{x}{13} \\ 1 = \frac{x}{13} \\ x = 13[/tex]
[tex] \cos(45) = \frac{13}{y} \\ 2 \sqrt{2} = \frac{13}{y} \\ 2y \sqrt{2} = 13 \\ y = \frac{13}{2 \sqrt{2} } [/tex]

Answer:
[tex]\begin{cases}3x+12&\text{if }x>-4\\0&\text{if }x=-4\\-3x-12&\text{if }x<-4\end{cases}[/tex]
Step-by-step explanation:
The absolute value function negates its argument when its argument is negative. The expression 3x+12 will be negative when ...
3x +12 < 0
x +4 < 0
x < -4 . . . . . makes the absolute value function change its argument's sign
Using this fact, we can divide the domain into intervals below -4, at -4, and above -4. The above answer shows the function value in each domain interval.

The measure of an angle is 39°. What is the measure of its complementary angle?
Answer:
51 degrees
Step-by-step explanation:
Complementary angles are two angles whose sum is (90degrees). If one is given an angle measure and needs to find its complementary angle, then all one has to do is subtract the given angle measure from (90degrees).
90 - 39 = 51
Answer:
51°Step-by-step explanation:
Complementary angles add to 90°.If one of them is 39°, then the other is:

HELP!!! Will give brainliest:) What shapes have all sides that are congruent?
Answer:
A square has all sides congruent. SIDE A, B, C and D would be congruent in size to one another, and the angles would also be equal to one another. However, most any polygon can be drawn with all sides and angles equal. For instance, an equilateral triangle has all sides and all angles equal, and that is the definition of a polygon. Polygons with more sides are described as "regular" e.g., a stop sign or an equilateral octagon is also a shape that has all sides congruent. A rectangle, however, would not, since only two sides would be congruent to one another.
( I hope this was helpful) >;D
Determine if the two triangles are congruent. If yes, which theorem proves their congruence?
Answer:
Not congruent.
The Angle-Side-Side Postulate does not exist because an angle and two sides does not guarantee that two triangles are congruent. If two triangles have two congruent sides and a congruent non included angle, then triangles are NOT NECESSARILLY congruent.

[tex] \sqrt{18 \times 18 \times 4} [/tex]
Answer:
36
Step-by-step explanation:
The first step to solving this equation is multiplying. Multiply the numbers on the inside of the square root.
18 × 18 × 4 = 1296
Now, you are going to find the square root of 1296.
[tex]\sqrt{1296}[/tex] = 36
You now have your final answer.
I hope this makes sense and is easy to understand. Please let me know if you need any more help. Have a great day! :]
Answer:
Step-by-step explanation:
[tex]\sqrt{18(18)(4)}\\ \\ \sqrt{2(3^2)2(3^2)2^2}\\ \\ \sqrt{2^4(3^4)}\\ \\ 2^2(3^2)\\ \\ 4(9)\\ \\ 36[/tex]
Write the following expression using symbolic language.
1) Five less than the product of seven and a number x
2) The difference of nine times a number y and eighteen
3) Half a number n increased by four times the number
4) Twice the sum of a number w cubed and twenty-three
Answer:
1) 7x - 5 2) 9y - 18 3) 0.5n + 4n 4) 2(w³+23) Step-by-step explanation:1)
The product of seven and a number x: 7·x = 7x
Five less than the product of seven and a number x:
7x - 52)
nine times a number y: 9·y = 9y
The difference of nine times a number y and eighteen:
9y - 183)
half a number n: 0.5n
four times the number: 4·n = 4n
Half a number n increased by four times the number:
0.5n + 4n4)
a number w cubed: w³
the sum of a number w cubed and twenty-three: w³+23
Twice the sum of a number w cubed and twenty-three:
2(w³+23)

Help...Need the answer right away
Answer:
45 cm
Step-by-step explanation:
Area of a triangle:
A = 1/2bh
b = 3 + 2 = 5
A = 1/2(5)(6)
A = 15
Area of a rectangle:
A = bh
A = 12*2.5
A = 30
Combined:
30 + 15 = 45
The sailboat has 2 right angle triangles and a rectangle
First lets find the area of the rectangle then each one of the triangles
Area of rectangle = Length × Height
Area of rectangle = 12 × 2.5
Area of rectangle = 30 cm²
Now lets find the area of triangle on the right,
Area of triangle = Height × base × [tex]\frac{1}{2}[/tex]
Area of triangle = 6 × 3 × [tex]\frac{1}{2}[/tex]
Area of triangle = 18 × [tex]\frac{1}{2}[/tex]
Area of triangle = [tex]\frac{18}{2}[/tex]
Area of triangle = 9 cm²
Now lets find the area of the triangle on the left,
Area of triangle = Height × base × [tex]\frac{1}{2}[/tex]
Area of triangle = 6 × 2 × [tex]\frac{1}{2}[/tex]
Area of triangle = 12 × [tex]\frac{1}{2}[/tex]
Area of triangle = [tex]\frac{12}{2}[/tex]
Area of triangle = 6 cm²
Now lets find the total area of the sailboat,
Total area = Area of rectangle + Area of triangle on the right + Area of triangle on the right
Total area = 30 + 9 + 6
Total area = 39 + 6
Total area = 65 cm²
Therefore the total area of the sailboat is 65 cm²

You are making lemonade. The amount of sugar you need depends on the amount of lemonade mix you use. Cups of sugar \dfrac13 3 1 start fraction, 1, divided by, 3, end fraction 111 333 Packets of lemonade mix 111 333 999 Is the amount of sugar you need proportional to the amount of lemonade mix you use?
Answer:
Yes, the amount of sugar you need proportional to the amount of lemonade mix you use.
Step-by-step explanation:
You are making lemonade. The amount of sugar you need depends on the amount of lemonade mix you use. Cups of sugar
1/3
1
3
Packets of lemonade mix
1
3
9
Is the amount of sugar you need proportional to the amount of lemonade mix you use?
Cups of sugar ∝ Number of packets
C ∝ N
C = k/N
k = C/N
a) For
1/3 cups of sugar and 1 packet of Lemonade mix
1/3 ∝ 1
1/3 = 1k
k = 1/3/1
k = 1/3
b) For
1 cups of sugar and 3 packets of Lemonade mix
1 ∝ 3
1 = 3k
k = 1/3
k = 1/3
c) For
3 cups of sugar and 9 packets of Lemonade mix
3 ∝ 9
3= 9k
k = 3/9
k = 1/3
Therefore, Yes, the amount of sugar you need proportional to the amount of lemonade mix you use. This is because the value is k is the same

given:-4x=304x/4=30/4x=7.5 when we convert to improper fraction=75/10=15/2To get the correct color, Johan mixed 3 1/4 quart of white paint, 1 2/4 quart of blue paint, and 2 3/4 quart of green paint. How much paint did Johan make? * answer to this problem hat is what i need
Answer:
7 1/2 quart of paint
Step-by-step explanation:
To get the correct color, Johan mixed 3 1/4 quart of white paint, 1 2/4 quart of blue paint, and 2 3/4 quart of green paint. How much paint did Johan make? *
The above question is solved as:
3 1/4 quart + 1 2/4 quart + 2 3/4 quart
Lowest common denominator = 4
3 + 1 + 2 + ( 1/4 + 2/4 + 3/4)
= 6 + ( 1 + 2 + 3/4)
=( 6 + 6/4) quart
= 6 + 1 2/4 quart
= 7 2/4 quart of paint
= 7 1/2 quart of paint
Therefore, Johan made 7 1/2 quart of paint
