Answers:

x = 141

y = 39

Explanation

Angle x and angle 141 are congruent because they are corresponding angles, and because the lines are parallel. Corresponding angles are in the same corner. In this case it's the northwest corner.

Angles x and y are supplementary. They glue together to get a straight line. Which means the angles add to 180.

x+y = 180

141+y = 180

y = 180-141

y = 39

What are the first three terms of the sequence a1 = 3 and an = 2(an-1)^2? I thought the answer was 3,18,32 but that's not an option! help????

Answers

Answer:

3,18,648

Step-by-step explanation:

We are asked to find out the first three terms of the sequence.

Recurring formula is given as

a_(n) =2(a_(n-1) ^2)

Since I term = 3

a_(2) =2(a_(1))^2=2(3^2)=18

Applying the same rule,

third term

=a_(3) =2(a_(2))^2\n=2(18^2)\n=648

Like this we can find out any number of terms using this recursive formula
a1=3
a2=2(3^2)=18
a3=2(18^2)=648

At a restaurant, you eat 2 taco salads and drink two glasses of ice tea. Your friend eats 1 taco salad and drinks 1 glass of ice tea. The restaurant charges you $11 and your friend $6.50. Can you determine the prices of taco salads and ice tea? Explain.

Answers

Set up a system of equations that represent x as taco salads and y as iced tea:
2x + 2y = 11 (you)
x + y = 6.50 (your friend)
Solve the system of equations by solving one of the equations for a variable:
x+y = 6.50 (I solved for y):
y = 6.50 - x.
Plug this equation into the y of the first equation:
2x + 2(6.50 - x) = 11
Solve for x:
2x + 13 - 2x = 11
2x cancels out:
13 = 11
No solution, so it is not possible to determine the prices of the items.

Step-by-step explanation:

Santino bought a book for $23.54. The price of the book was $22. What was the sales-tax rate?

Answers

We first find value of tax in dollars.

The difference between the two prices  is: 23. 54 - 22 = 1.54

Therefore the sales tax in dollars is 1.54

The tax % will be  (amount of tax / original cost price ) × 100

(1.54 / 22) × 100 → (0.07) × 100 =  7

So the tax rate is 7%

We can double check the answer.

7 % of 22  → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54
