The lunch check for Helen is $16.98. What will
the tip amount be if she would like to tip 18%?

Answer:

The equation of the exponential function will be:

Step-by-step explanation:

The general exponential function is defined as

y = abˣ

Here,

From the table, it is clear that the y-intercept is (0, 10). Note that the y-intercept can be determined by setting x=0 and solving for y.

here

at x=0, y=10

so a = 10

If we check the y-values, it is clear that every next value of y can be obtained by multiplying the previous y-value by 1/5.

In other words, the common multiplier = b = 1/5

Thus, the equation becomes

[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]

Thus, the equation of the exponential function will be:

Answer:

Convert to decimals:

1.5 and 0.75

Then, set up a proportion

1.5/0.75=x/1

proportion x/y=x/y

since the 3/4 and 1 are the same topic ( the room) we put them together.

Solve: 1.5/0.75=x

x=2

So 2 gallons

Answer:

x = -1, y = -1

( -1 , -1 )

Step-by-step explanation:

plug in -9y - 10 for x

5 ( -9y - 10) + 6y = -11

-45y - 50 + 6y = -11

-39y - 50 = -11

-39y = 39

y = -1

then plug in

-9(-1) - 10 = x

9 - 10 = x

x = -1

Answer:

The answer is D-16

Step-by-step explanation:

Since we have x on one side, and 49 degrees on the other, both angles are the same, so we subtract 1 from 49 to get 48, so that 3x has to equal 48. So we just divide 48 by 3 to get 16, so x = 16.

Answer:

3240°

Step-by-step explanation:

Using the formula:

sum of interior angle = (n - 2) * 180 (where n is the number of sides)

sum of interior angle = (20 - 2) * 180

sum of interior angle = 18 * 180

sum of interior angle = 3240° ANS

Answer:

3,406.5 litres/hr

Step-by-step explanation:

The liquid is being poured at a rate of 15 gallons per minute.

1 minute = 1/60 hour

Thus, the rate can be written as:

15 gallons pet 1/60 hour

We are told that one gallon is approximately 3.785 liters.

Thus;

15 gallons = 15 × 3.785 litres = 56.775 litres.

Thus, the rate is;

56.775 litres per 1/60 hour

We want to find in litres/hr.

By proportion, we have it as;

(56.775 ÷ 1/60)/1 = 56.775 × 60 = 3,406.5 litres/hr

Answer:

Step-by-step explanation:

no because each y value doesn’t increase uniformly

Answer: false

Step-by-step explanation:

The x and y both have to have to same number between each by the y doesn’t

Since $14 is the price after a 30% discount then $14 is 70% of the original price.

$14/70=x/100 (100% would be the original price)

1400=70x or 1400/70 = $20!

You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!

Answer:

Explanation: Since the equation is linear/straight in the form y=mx+c , you can determine the slope/gradient ( m ) and y-intercept ( c ). To graph this equation, you'll need to find 2 points on the line and join them together. We know one of the points is (0, 1) as the y-intercept is 1.

Step-by-step explanation:

Russia is 2 × 10³ times larger than Puerto Rico.

Exponentiation is a method of writing numbers, especially larger numbers, as the power of some number. A number can be written in the exponent form as aᵇ, where 'a' is called the base and 'b' is called the power or exponent.

Total land area of Russia = 20,000,000 km² = 2 × 10⁷ km²

Total land area of Puerto Rico = 10,000 km² = 10⁴ km²

Let X be the number of times that Russia is larger than Puerto Rico.

Then we can write,

Total land area of Russia = X × Total land area of Puerto Rico

2 × 10⁷ km² = X × 10⁴ km²

X = 2 × 10⁷ km² / 10⁴ km²

X = 2 × 10⁷ × 10⁻⁴

X = 2 × 10³

Hence, about 2 × 10³ times larger is Russia than Puerto Rico.

The sequence has a common difference, and the common difference of the arithmetic sequence is 10/3

The given parameters are:

T6 = 32

T12 = 52

The nth  term of an arithmetic progression is:

Tn = a + (n - 1) * d

So, we have:

T6 = a + 5d = 32

T12 = a + 11d = 52

Subtract both equations

a - a + 11d - 5d = 52 - 32

Evaluate

6d = 20

Divide both sides by 6

d = 10/3

Hence, the common difference is 10/3
