Answer:
1/8
Step-by-step explanation:
The lowest common multiple of 4 and 8 is 8.
1/4 = 2/8
3/8 - 1/4 = 3/8 - 2/8 = (3 - 2)/8 = 1/8

Angelica says the tangent is the ratio of the length of the leg opposite angle A ∠ A over the length of the leg adjacent to angle A This means B C must have a length of 3 3 units A C must have a length of: 4 4 units. They can find the length of Latex A B using the Pythagorean Theorem and then use it to find the sine and cosine ratios. Graciella says that they cannot find the length of any side of the triangle and, therefore, cannot find the ratios for sine and cosine. Both students have errors in their reasoning.

Answers
Based on the trigonometry ratios and the Pythagorean theorem both of them were incorrect.
Cos A = 4/5; Sin A = 3/5
What is the Trigonometry Ratios?The Trigonometry ratios relates the length of the sides of a right triangles. They are given as:
Sine ratio, sin ∅ = opp/hypCosine ratio, cos ∅ = adj/hypTangent ratio, tan ∅ = opp/adj.What is the Pythagroean Theorem?If two sides of a right triangle are known the third side can be determined using the Pythagorean theorem, which is given as, c² = a² + b², where and b are legs, and c is the hypotenuse of the right triangle.
1. Given that tan A = 3/4, it is not necessarily true that BC MUST have a length of 3 units, and AC MUST have a length of 4 units, because:
If BC = 9 units and AC = 12 units, the it will give us the same tangent ratio as:
tan A = 9/12 = 3/4.
Therefore, Angelica's mistake is stating that BC MUST be 3 units, and AC MUST be 4 units.
2. Knowing two length of the sides of a right triangle is enough information needed to find the length of the third side using the Pythagorean theorem, so Graceilla is incorrect.
3. Find AC using the Pythagorean theorem:
AB = √(3² + 4²)
AB = 5 units.
Cos A = adj/hyp = AC/AB
Cos A = 4/5
Sin A = opp/hyp = BC/AB
Sin A = 3/5

You want to buy a new computer for $1500. You only have $500 right now, so you decide to deposit the money into an account yeilding 5% interest compounded monthly, how long until you have enough to buy the computer
Answers
Answer:
Twenty-two months (a year and ten months)
Step-by-step explanation:
First, we have to find how much is 5% of 500
500 x 0.05 = 25
Next, you add it to 500
so after the first month, you will have $525
Then, we have to find 5% of 525
525 x 0.05 = 26.25
meaning that after the second month, you'll have $551.25
We keep on repeating these steps until we reach the desired amount.
month three:
$551.25 x 0.05 = 27.5625
551. 25 + 27.5625 = 578.8125
month four:
578.8125 x 0.05 = 28.940625
578.8125 + 28.940625 = 607.753125
month five:
607.753125 x 0.05 = 30.38765625
607.753125 + 30.38765625 = 638.14
month six:
638.14 x 0.05 = 31.91
638.14 + 31.91 = 670.05
month seven:
670.05 x 0.05 = 33.51
670.05 + 33.51 = 703.55
month eight:
703.55 x 0.05 = 35.18
703.55 + 35.18 = 738.73
month nine:
738.73 x 0.05 = 36.94
738.73 + 36.94 = 775.67
month ten:
775.67 x 0.05 = 38.78
775.67 + 38.78 = 814.45
month eleven:
814.45 x 0.05 = 40.72
814.45 + 40.72 = 855.17
month twelve:
855.17 x 0.05 = 42.76
855.17 + 42.76 = 897.93
month thirteen:
897.93 x 0.05 = 44.90
897.93 + 44.90 = 942.83
month fourteen:
942.83 x 0.05 = 47.14
942.83 + 47.14 = 989.97
month fifteen:
989.97 x 0.05 = 49.50
989.97 + 49.50 = 1039.47
month sixteen:
1039.47 x 0.05 = 51.97
1039.47 + 51.97 = 1091.44
month seventeen:
1091.44 x 0.05 = 54.57
1091.44 + 54.57 = 1146.01
month eighteen:
1146.01 x 0.05 = 57.30
1146.01 + 57.30 = 1203.31
month nineteen:
1203.31 x 0.05 = 60.17
1203.31 + 60.17 = 1263.48
month twenty:
1263.48 x 0.05 = 63.17
1263.48 + 63.17 = 1326.65
month twenty-one:
1326.65 x 0.05 = 66.33
1326.65 + 66.33 = 1392.98
month twenty-two:
1392.98 x 0.05 = 69.65
1392.98 + 69.65 = 1462.63
month twenty-three:
1462.63 x 0.05 = 73.13
1462.63 + 73.13 = 1535.76
So your final answer would be that it would take twenty-two months (a year and ten months) to have enough money to buy the computer.

Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola
The vertex of a parabola is the point at the top or bottom of the parabola
Step-by-step explanation:
Different textbooks have different interpretations of the reference "standard form" of a quadratic function. Some say f (x) = ax2 + bx + c is "standard form", while others say that f (x) = a(x - h)2 + k is "standard form". To avoid confusion, this site will not refer to either as "standard form", but will reference f (x) = a(x - h)2 + k as "vertex form" and will reference f(x) = ax2 + bx + c by its full statement.

Estimate the amount of the tip by rounding the bill to the nearest ten dollars before calculating.
15% tip on a bill of $551.60
The amount of the tip is approximately $
Answers
Answer:
$82.50
Step-by-step explanation:
This problem requires you round the given bill value, then compute a fraction of that rounded value.
__
RoundingWe want to round the bill value to the nearest $10. The digit to the right of the tens digit is 1, so we simply replace that and all digits to the right with zeros. (Had the ones digit been 5 or more, we would increment the tens digit before zeroing digits to its right.)
$551.60 rounded to nearest $10 is $550.00
__
Tip AmountThe amount of the tip is found by multiplying the bill by the tip rate.
$550 × 15% = $550 × 0.15 = $82.50
The amount of the tip is approximately $82.50.
_____
Additional comment
It is often relatively easy to compute a tenth or half of something in your head. We know that 15% = 10% + (1/2)(10%), and that 10% of $550 is $55.
Half of $55 is $27.50, so the tip amount will be $55.00 +27.50 = 82.50, a calculation you can do mentally.

find the missing side of this triangle 6 x 10
Answers
Answer:
√136 units
Step-by-step explanation:
We are given that;
The provided triangle is a right triangle.The measure of the legs are 6 and 10 units.The hypotenuse of the right triangle is x units.Since the provided triangle is a right triangle, we can use pythogoras theorem to determine the missing side length of the triangle.
What is the pythogoras theorem and it's formula?Pythogoras theorem is a formula that is used to determine the missing side length of a right triangle, with the following given;
Two side lengths (Legs)A hypotenuse (Longest side)Pythogoras theorem is denoted as;
(c)² = (b)² + (a)²Where, "c" is the hypotenuse; "b" and "a" are the legs.
When we substitute the measure of the two legs and the hypotenuse of the triangle, we get;
(x)² = (10)² + (6)²Now, let's simplify the equation to determine the value of "x".
⇒ (x)² = 100 + 36 [Evaluating the squares]⇒ (x)² = 136 [Simplifying the right-hand-side]⇒ √(x)² = √136 [Taking square root both sides]⇒ x = √136 ≈ 11.66 units (2 d.p) [Taking square root both sides]The measure of the missing side is √136 units.

Which function is the inverse of f(x)=-5x-4
Answers
Hello!
Let's solve this question with the information given to us in the question.
We were given the function, f(x) = -5x - 4, or also known as y = -5x - 4
With the function we need to find the inverse of it.
We can simply flip the "x" and "y" variables in the function and solve.
Solve:
y = -5x - 4
Flip the "x" and "y" variables.
x = -5y - 4
Now, solve for "y".
x = -5y - 4
Add 4 to both sides of the equation.
x + 4 = -5y
Divide everything by -5 to get "y" by itself.
-1/5x - 4/5 = y
Therefore, the inverse of the function would be [tex]-\frac{1}{5}x -\frac{4}{5}[/tex]
Answer:
Your answer would be A). [tex]-\frac{1}{5}x -\frac{4}{5}[/tex]
