HELP I NEED HELP WITH 1,2 and 8

Mathematics
1 answer:
Yanka [14]3 years ago
7 0

Answer:

$19.79

Step-by-step explanation:

The only problem provided is #8, so I will help on that one lolz.

First, you find 10% of $19.99.

That is $2

This is a discount, so subtract 2 from the original, 19.99.

You get 17.99.

Adding a sales tax of 10% is $1.80.

This makes $19.79

Find the value of x, y, and z in the rhombus below.
Yuki888 [10]

Solution:

<u>It should be noted:</u>

  • Opposite sides of a rhombus are always equal.
  • Opposite angles of a rhombus are always equal.

<u>Thus:</u>

  • (-y - 10) = 90°
  • 3z - 3 = 90°
  • 4x - 2 = 90°

<u>Finding x:</u>

  • 4x - 2 = 90°
  • => 4x = 90 + 2
  • => 4x = 92
  • => x = 23

<u>Finding y:</u>

  • (-y - 10) = 90°
  • => -y - 10 = 90°
  • => -y = 100
  • => y = -100

<u>Finding z:</u>

  • 3z - 3 = 90°
  • => 3z = 90 + 3
  • => 3z = 93
  • => z = 31

What is the maximum value of P = 4x + 2y, given the constraints on x and y listed below?
Solnce55 [7]
P = 4x + 2y

additional info.
<span>x+2y  <u><</u> 10
y <u><</u> 2
x <u>></u> 0
y <u>></u> 0

y can only be 0, 1, and 2.

x + 2(0) <u><</u> 10 = x <u><</u> 10
x + 2(1) <u><</u> 10 = x + 3 <u><</u> 10 = x <u><</u> 10 - 3 = x <u><</u> 7
x + 2(2) <u><</u> 10 = x + 4 <u><</u> 10 = x < 10 - 4 = x <u><</u> 6

x = 10 ; y = 0 : P = 4(10) + 2(0) = 40 + 0 = 40
x = 7 ; y = 1 : P = 4(7) + 2(1) = 28 + 2 = 30
x = 6 ; y = 2 : P = 4(6) + 2(2) = 24 + 4 = 28

The maximum value of P is 40. Where x is 10 and y is 0.</span>
