At lunch, Noah buys two tacos for $2.35 each, chips and salsa for $1.85, and lemonade for $1.60. To pay for his meal, he uses $5

.00 from a gift card he has, and then he pays for the rest with a $20.00 bill. Which equations show how much change Noah receives? A. $ 2 . 35 + $ 1 . 85 + $ 1 . 60 = $ 5 . 80 $ 5 . 80 − $ 5 . 00 = $ 0 . 80 $ 20 . 00 − $ 0 . 80 = $ 19 . 20 B. $ 2 . 35 + $ 1 . 85 + $ 1 . 60 + $ 5 . 00 = $ 10 . 80 $ 20 . 00 − $ 10 . 80 = $ 9 . 20 C. $ 2 . 35 + $ 2 . 35 + $ 1 . 85 + $ 1 . 60 = $ 8 . 15 $ 8 . 15 − $ 5 . 00 = $ 3 . 15 $ 20 . 00 − $ 3 . 15 = $ 16 . 85 D. $ 2 . 35 + $ 2 . 35 + $ 1 . 85 + $ 1 . 60 + $ 5 . 00 = $ 13 . 15 $ 20 . 00 − $ 13 . 15 = $ 6 . 85

Find the area of a parallelogram with base 15 yards and height of 21 2/3
VARVARA [1.3K]
To find the area of a parallelogram, you use the area formula:

Area = Base * Height

Then, all you have to do is substitute in your known integers and solve. Therefore:

Area = 15 * 21 2/3

When we multiply these two numbers, we get 

Area = 325 square yards or yardsyards^{2}

If and , find .<br><br> A. <br> B. <br> C. <br> D.
trapecia [35]
Answer: option D. 2x^2 + (3/2)x  - 5

Explanation:

1) polynomials given:

 f(x) = x/2 - 2 and g(x) = 2x^2 + x - 3

2) question: find (f + g) (x)

That means that f(x) + g(x), so you have to add up the two polynomials given.

3) x/2  - 2 + 2x^2 + x - 3

4) Combine like terms:

a) terms with x^2: you only have 2x^2, so it is not combined with other term.

b) terms with x: x/2 + x

that is a sum of fractions: x/2 + x = [x + 2x] / 2 = 3x / 2 = (3/2)x

c) constant terms: - 2 + (-3) = - 2 - 3 = - 5

5) Result: 2x^2 + (3/2)x - 5

That is the option d.
