If you have a 30 degree reference angle, the side opposite (the side not part of the reference angle) is 1/2 the size of the hypotenuse.
Since the side opposite is 12, the hypotenuse is easily found.
1/2 = opposite / hypotenuse
1/2 = 12 / hypotenuse Cross multiply
hypotenuse = 2 * 12
hypotenuse = 24
Now use the Pythagorean Theorem to get the third side.
c = 24
a = 12
b = ?
a^2 + b^2 = c^2
12^2 + b^2 = 24^2
144 + b^2 = 576 Subtract 144 from both sides.
b^2 = 576 - 144
b^2 = 432
Now you have to factor 432 down to its primes
432 = 2 * 2 * 2 * 2 * 3 * 3 * 3
The rule is for every two 2s you take one outside the root sign and throw the other one away. If there are an odd number of factors, leave one of them under the root sign.
sqrt(b^2) = sqrt(432)
b = 4 * 3sqrt(sqrt(3))
b = 12 sqrt(3)
Answer
r = 12*sqrt(3)
t = 24
The answer is D

A shoe company started a website 2 years ago. The first year, the website received h hits. The second year, it received 132 % of the hits it received the first year. Which expression will result in the number of hits the company's website received the 2 nd year? 1 + 0.32 h 1 plus 0 point 3 2 h, 1.32 h 1 point 3 2 h, ( 1 + 1.32 ) h open paren 1 plus 1 point 3 2 close paren times h, h + 1.32 h , h plus 1 point 3 2 h,
Answer:
B. 1.32 h : 1 point 3 2 h
Step-by-step explanation:
Year 1 = h hits
Year 2 = 132 % of the hits it received the first year
Number of hits the company's website received the 2nd year = 132% of h
= 132/100 × h
= 1.32 × h
= 1.32h
A. 1 + 0.32h : 1 plus 0 point 3 2 h,
B. 1.32 h : 1 point 3 2 h,
C. ( 1 + 1.32 ) h : open paren 1 plus 1 point 3 2 close paren times h,
D. h + 1.32 h : h plus 1 point 3 2 h,

For which value of p and q does the following pair of linear equations have an infinite
number of solutions?
2x + 3y = 7
( p-q ) x + (p+q) y = 3 p + q -2
Answer:
[tex]p =2.5[/tex]
[tex]q = 0.5[/tex]
Step-by-step explanation:
Given
[tex]2x + 3y = 7[/tex]
[tex]( p-q ) x + (p+q) y = 3 p + q -2[/tex]
Required
Find p and q
To do this, we make direct comparison between the given expressions.
[tex]2x + 3y = 7[/tex] and [tex]( p-q ) x + (p+q) y = 3 p + q -2[/tex]
This implies that:
[tex](p - q)x = 2x[/tex]
[tex](p+q)y = 3y[/tex]
[tex]3(p + q) - 2 = 7[/tex]
So, we have:
[tex]p - q = 2[/tex] --- (1)
[tex]p+q =3[/tex] -- (2)
[tex]3(p + q) - 2 = 7[/tex] --- (3)
If [tex](1)\ and\ (2)[/tex] are true, then [tex](3)\ must[/tex] be true.
So, we only solve [tex](1)\ and\ (2)[/tex]
Add (1) and (2) to eliminate q
[tex]p+p-q+q=2+3[/tex]
[tex]2p=5[/tex]
Solve for p
[tex]p = 5/2[/tex]
[tex]p =2.5[/tex]
Substitute [tex]p =2.5[/tex] in (2)
[tex]p+q =3[/tex]
[tex]q = 3 - p[/tex]
[tex]q = 3 - 2.5[/tex]
[tex]q = 0.5[/tex]

Answer:
24°
Step-by-step explanation:
Supplementary angles: angles that add up to 180°
Thus, ∠A + ∠B = 180°
=> (x + 6)° + (7x + 30)° = 180°
=> 8x + 36 = 180
=> 8x = 180 - 36
=> 8x = 144
=> x = 18
∠A = (18 + 6)° = 24°
1. Which of the following is the equation of a circle with center (a, −b) and radius r?
A. (x−a)2+(y+b)2=r2
B. (x+a)2+(y−b)2=r2
C. (x+a)2+(y−b)2=r
D. (x−a)2+(y+b)2=r
2. A given circle has the equation x2+y2−4x−2y+4=1. What is the center of the circle?
A. (1, 2)
B. (−2, −1)
C. (−1, −2)
D. (2, 1)
Answer:
1) A
2) D
Step-by-step explanation:
1) The equation of a circle is (x-h)²+(y-k)²=r² where (h,k) is the center and "r" is the radius of the circle. With a center of (a,-b) the equation of the circle is (x-a)²+(y+b)²=r² making A the correct answer.
2) Convert from general form into standard form:
Given: x²+y²-4x-2y+4=1
Rearrange: x²-4x+4+y²-2y=1
Set right side equal to 0: x²-4x+4+y²-2y-1=0
Complete the square: x²-4x+4+y²-2y-1+2=0+2
Evaluate: x²-4x+4+y²-2y+1=2
Condense: (x-2)²+(y-1)²=2
Therefore, the center of the circle is D) (2,1)
GEOMETRY HELP PLEASE!! WILL MARK BRAINLEIST!

Answer:
53°
Step-by-step explanation:
Let m∠BCA = 'x'
Because it states that quadrilateral ABCD is a rectangle (sorry, forgot to say that in my image), that means that angles ∠ABC, ∠BCD, ∠CDA and ∠DAB are all right angles. That also means that all those angles are 90°.
Since ∠ACD is a portion of ∠BCD, (37° is a portion of 90°), and we're looking for the complement of ∠ACD, all we have to do is subtract 37° from 90°.
90 - 37 = 53
Hence, the answer is 53°
A cylindrical cup is 8 centimeters in height. When filled to the very top, it holds 480 cubic centimeters of water. What is the radius of the cup, rounded to the nearest tenth? Explain or show your reasoning.
Answer:
4.4cm
Step-by-step explanation:
The area of a circle is [tex]\pi r^{2}[/tex], where r is the radius.
Hence the volume of the cylinder would be [tex]\pi r^{2}h[/tex], where r is the radius and h is the height of the cylinder.
We can set up an equation V = [tex]\pi r^{2}h[/tex]
If we plug in the values we know, V=480, h=8, then we get [tex]480=8\pi r^{2}[/tex]
If we divide both sides be 8pi and square root both sides after that, we can find the value of r.
[tex]r = \sqrt{\frac{480}{8\pi } } =4.37019[/tex]
To the nearest tenth, the radius would round up, yielding 4.4cm
Is a acute triangle regular?
Answer:
An equilateral triangle may also be called a "regular" triangle. (A "regular" polygon has all equal sides and all equal angles.)An acute triangle has all angles measuring less than 90º. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral.

How many flowers, spaced every 3 in., are needed to surround a circular garden with a 125 -ft radius? Use 3.14 for (the pie symbol).
Answer:
785
Step-by-step explanation:
flowers needed to surround the garden = circumference of the garden / space
circumference of a circle = 2nr
n = 3.14
r = radius
The radius is in ft and the space is in inches. i would convert the ft to inches to aid comparability
1ft = 12 inches
125 x 3 = 375
2 x 3.14 x 375 = 2355
flowers needed = 2355 / 3 = 785
Which equation represents the parent function translated to the right 4 units and stretched by a factor of 5?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. So, I will solve a general solution, instead.
Let (x,y) be the parent function
First transformation: 4 unit right translation
The rule to this is: [tex](x,y) \to (x + b,y)[/tex]
Where b is the units of translation
i.e. [tex]b = 4[/tex]
So, we have;
[tex](x,y) \to (x + 4,y)[/tex]
Second transformation: Stretch by a factor of 5
The rule to this is: [tex](x,y) \to (x ,ay)[/tex]
Where a is the units of translation
i.e. [tex]a = 5[/tex]
So, we have;
[tex](x + 4,y) \to (x+4,5y)[/tex]
Hence, the transformation from the parent function to the new function is:
[tex](x + 4,y) \to (x+4,5y)[/tex]

Answer: 30
Step-by-step explanation:
3(0.3m + 6) + m =75
(0.3 x 3 = 0.9)
(6 x 3 = 18)
0.9m + 18 + m = 75
0.9m + m + 18 = 75
(m=1)
1.9m + 18 = 75
1.9m = 75 - 18
1.9m = 57
m = 57÷ 1.9

Camila owns a car worth $5,900 and owes $2,800 on the car loan. She has $1,600 in her bank account and $5,210 in a savings account. She has a balance of $1,400 on her credit card. What is her net worth?
Answer:
[tex]Net\ Worth=11310[/tex]
Step-by-step explanation:
From the question we are told that:
Car worth [tex]C=5900\$[/tex]
Car Loan[tex]L=2800\$[/tex]
Bank account [tex]B= 1600\%[/tex]
Savings account [tex]S=5210\&[/tex]

is 6:4 and 4:3 equivalent ratios?
Answer:
nooooo
Step-by-step explanation:
an equivalent ratio to 6:4 would be 3:2 and an equivalent ratio for 4:3 would be 8:6
hope this helps! :)
The ratios 3:2 and 4:3 are not the same ratio, we can conclude that 6:4 and 4:3 are not equivalent ratios.
What are ratios and proportions?A proportion is a statement that two ratios are equal. It compares two ratios and states that they are equivalent.
No, the ratios of 6:4 and 4:3 are not similar. We must reduce each ratio to its simplest form in order to determine whether two ratios are equivalent (by dividing both the numerator and denominator by their greatest common factor).
For 6:4, the greatest common factor is 2, so we can simplify to:
6:4 = 3:2
For 4:3, there are no common factors other than 1, so it is already in its simplest form.
Since 3:2 and 4:3 are not the same ratio, we can conclude that 6:4 and 4:3 are not equivalent ratios.

Answer:73.6fr^3
Step-by-step explanation:
The volume of the sphere is [tex]73.57ft^3[/tex].
What is the volume of sphere?
The volume of sphere is the amount of space occupied, within the sphere. The sphere is defined as the three-dimensional round solid figure in which every point on its surface is equidistant from its centre.
[tex]V=\frac{4}{3}\pi r^3[/tex]
here [tex]r[/tex] is the radius and it is [tex]r=2.6ft[/tex]
So,
[tex]V=\frac{4}{3}\pi r^3\\\\V=\frac{4}{3}(3.14)(2.6)^3\\\\V=\frac{4}{3}(3.14)(17.576)\\\\V=\frac{4(55.18)}{3}\\\\V=\frac{220.72}{3}\\\\V=73.57ft^3[/tex]
