The Rodriguez family went to dinner at at Pasta Palace. Mr. Rodriguez ordered a meal for $6.25; Mrs. R ordered a meal for $7.50;

lidiya [134]

Cost of the meal ordered by Mr. Rodriguez = $6.25
Cost of the meal ordered by Mrs. Rodriguez = $7.50
Cost of each pizza ordered by the two children = $4.99
Then
The cost of the 2 pizzas ordered by the 2 children = (2 * 4.99) dollars
   = 9.98 dollars
So
The total cost of the orders = (6.25 + 7.50 + 9.98) dollars
   = 23.73 dollars
Percentage of tip on the bill = 15%
Then
Amount of tip paid = (15/100) * 23.73 dollars
      = 355.95/100 dollars
      = 3.56 dollars
Percentage of tax paid on the bill = 7.25%
Amount of sales tax that was paid = (7.25/100) * 23.73 dollars
   = 172.04/100 dollars
   = 1.72 dollars
So
The total bill that was paid = (23.73 + 3.56 + 1.72) dollars
   = 29.01 dollars

Find the eccentricity e and the distance ldI from the pole to the directrix of the conic

nikitadnepr [17]

Answer:

The answer is "eccentricity = 0.5 and distance = 60".

Step-by-step explanation:

Given value:

$\bold{r=\frac{420}{ -14 +7 \sin \theta}}$

Standard equation formula:

$\bold{\to r=\frac{ep}{1- e \sin \theta}}$

$\to r=\frac{\frac{420}{-14}}{1- \frac{7}{14} \sin \theta}\\\\\to r=\frac{ -30 }{1- \frac{1}{2} \sin \theta}\\\\\to r=\frac{ -30 }{1- 0.5 \sin \theta}\\\\$

$\boxed{ r=\frac{-30 }{1- 0.5 \sin \theta}}$

compare the above value with the Standard equation:

$\to e=0.5 \\ \to ep= -30\\$

calculating the value of p:

$\to 0.5 p= -30\\\\\to p= \frac{-30}{0.5}\\\\\to p= \frac{-300}{5}\\\\\to p= - 60$

eccentricity (e) = 0.5

distance = - 60

distance |d| = 60

98 x 63 – 32 x 69 =

Dahasolnce [82]

Answer:

3966

Step-by-step explanation:

Use order of operations to solve this problem:

Parentheses
Exponents
Multiply (Left to right)
Divide (Left to right)
Addition
Subraction

In your case, there are no parentheses or exponents, so we can skip right the the multiply and divide step. The first multiplication is 98*63=6174. The next step is to do 32*69=2208. Then you minus 6174-2208=3966.

Hope this helps!
