Since there are more than 6 people at the table, we know that the 18% gratuity is going to be charged. In order to multiply a number by a percent, you need to first convert it to a decimal and 18% as a decimal is .18. Just the gratuity would be .18p, but, this is where they're trying to trick you. It is asking for the total cost of the meal including gratuity. The whole meal is 100%, so you add 100%to 18% and get 118%. 118% converted to a decimal is 1.18, so the total cost of the meal including gratuity can be expressed by 1.18p.

The width of a triangle is six more than twice the height. The area of the triangle is 88in2. Find the height and base of the tr
malfutka [58]

For this case we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

Where:

b: It is the base of the triangle

h: It is the height of the triangle

According to the statement data we have:

b = 6 + 2h

Substituting we have:

88 = \frac {(6 + 2h) * h} {2}\\176 = 6h + 2h ^ 2\\2h ^ 2 + 6h-176 = 0

We divide between 2 on both sides:

h ^ 2 + 3h-88 = 0

We factor by looking for two numbers that, when multiplied, are obtained -88 and when added together, +3 is obtained.

These numbers are +11 and -8.

(h + 11) (h-8) = 0

We have two roots:

h = -11\\h = 8

We choose the positive value.

Thus, the base of the triangle is:b = 6 + 2 (8) = 22

Answer:

The base of the triangle is 22 units.

Estimate the unit rate to the nearest hundredth.<br><br> $1.19 per 12fl oz price of 1 fl oz
Korvikt [17]
To find the unit rate you need to divide the 1.19 by 12 so that the ounces would be the price per 1 ounce.
1.19/12 = .099 per ounce
Since we are talking about money your answer needs to be rounded to TWO decimals unless told otherwise.
Rounding .099 would be $ 0.10 per ounce

The orbital period, P, of a planet and the planet's distance from the sun, a, in astronomical units is related by the formula P
anygoal [31]

Answer:

a for saturn is 9.55 astronomical units

Step-by-step explanation:

Here, we are interested in calculating the distance from the sun.

Mathematically, from the question;

P = a^3/2

29.5 = a^3/2

a = 29.5^2/3

a = [3√(29.5)]^2

a = 9.55 in astronomical units

Isabella filled her pool with water at a constant rate.
Anon25 [30]

Answer:

The size of Isabella's pool is 220 liters.

Step-by-step explanation:

Let the size of Isabella's pool be x liters, R be the rate of fill, t be the time of fill and V be the volume of water filled in the pool.

As the rate of fill is constant,

Therefore, volume of water filled in the pool can be given as,

V= Rt

Volume of water left is given as x-V=x-Rt

From the table,

Volume of water left after t=2 minutes is 184 liters.

So, x-R(2)=184\\x-2R=184 -------- 1

Volume of water left after t=12 minutes is 4 liters.

So, x-R(12)=4\\x-12R=4 ------------2

Multiply equation 1 by 6 and equation 2 by -1, we get

6x-12R=1104\\-x+12R=-4

Now, we add the above equations, we get

(6x-x)+(12R-12R)=1104-4\\5x=1100\\x=\frac{1100}{5}=220

Therefore, the size of Isabella's pool is 220 liters.
