The answer is C. A fraction is basically another way of writing division, and  six divided by three is two.

Answer:

  $82.50

Step-by-step explanation:

This problem requires you round the given bill value, then compute a fraction of that rounded value.

__

We 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

__

The 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.

Answer:

x = 24°

Step-by-step explanation:

Here we can see that 120° with the right angle is equal to 180° :

120° + right angle = 180°

then:

right angle = 180° - 120° = 60°

The right angle with 5x angle is equal to 180° too ;

right angle + 5x = 180°

solve for x :

5x = 180° - 60°

x = 24°

That its.

Answer:

5/9

Step-by-step explanation:

Let the probability of getting a multiple of 3 is "A"

Let the probability of getting an even number is "B"

Total number of outcomes=36

Total number of favourable outcomes of either a multiple of 3 or an even number are

(1,1) ,(1,2) ,(2,1) ,(1,3) ,(3,1) ,(2,2) ,(1,5) (5,1) ,(3,3) ,(2,4) ,(4,2) ,(2,6) ,(6,2) ,(3,5) ,(5,3) ,(4,4) ,(6,4) ,(4,6) ,(5,5) ,(6,6)

That is we have 20 favourable outcomes

Hence, Probability=\frac{\text{favourable outcomes}}{\text{total number of outcomes}}Probability=

total number of outcomes

favourable outcomes

Therefore, after substituting the values we get

probability=\frac{20}{36}probability=

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]

Step-by-step explanation:

The function that  represents the amount of money in the account after t years is f(t) = $2000(1.0033^12t).

The money in his account in five years would be $2442.

The number of years it would take to have a value over $2500 is 6 years.

The formula for calculating future value:

FV = P (1 + r)^nm

f(t) =  $2000(1.0033^60) = $2442

f(6) =  $2000(1.0033^72) = 2535.41

Answer:

t = 74.897 years

(about 74 years 11 months)

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 4/100

r = 0.04 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(16,000.00/800.00) / ( 365 × [ln(1 + 0.04/365)] )

t = ln(16,000.00/800.00) / ( 365 × [ln(1 + 0.00010958904109589)] )

t = 74.897 years

Summary:

The time required to get a total amount of $16,000.00 with compoundeded interest on a principal of $800.00 at an interest rate of 4% per year and compounded 365 times per year is 74.897 years.

(about 74 years 11 months)

Since it wasn't stated howmany times the interest is compunded I took the value of once a year.

Answer:

-8

Step-by-step explanation:

lim x⇒0 (x²-8) = 0-8 = -8

Based on the trigonometry ratios and the Pythagorean theorem both of them were incorrect.

Cos A = 4/5; Sin A = 3/5

The Trigonometry ratios relates the length of the sides of a right triangles. They are given as:

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

Answer:

Step-by-step explanation:

Check the picture below.

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.

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.
