Five light bulbs that are either on or off are lined up in a row. A certain code uses different combinations of lights turned on

Paraphin [41]

Answer:

Step-by-step explanation:

The number of different ways that 2 lights can be chosen from 5 is ₅C₂. Use a calculator or find the value manually:

₅C₂ = 5! / (2! (5−2)!)

₅C₂ = 5! / (2! 3!)

₅C₂ = 5×4×3×2×1 / (2×1 × 3×2×1)

₅C₂ = 5×4 / 2

₅C₂ = 10

Jasmyn uses 42% of a gift card to buy groceries if she spent $67.20 on groceries, how much was on the gift card to begin with

lapo4ka [179]

Answer:

The card was worth $160.

Step-by-step explanation:

It is given that:

Percent of gift card used = 42%

Cost of groceries = $67.20

Let,

x be the total amount on gift card.

42% of x = 67.20

$\frac{42}{100}x=67.20$

0.42x = 67.20

$\frac{0.42x}{0.42}=\frac{67.20}{0.42}\\x=160$

Therefore,

The card was worth $160.

For the circle with equation (x-2)^2+(y+3)^2=9, answer each question. a) whats coords of the center? b) what are the radius and

MrRissso [65]

Answer:

<h2>a) center (2, -3)</h2><h2>b) radius r = 3</h2><h2>c) in the attachment</h2>

Step-by-step explanation:

The standard form of an equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have:

$(x-2)^2+(y+3)^2=9\\\\(x-2)^2+(y-(-3))^2=3^2$

a) center (2, -3)

b) radius r = 3

c) in the attachment

Based on Pythagoras' theorem, how would you explain the structure of the Egyptian pyramids?

cricket20 [7]

It is known to us that the Eqyptian pyramids have a square-shaped base and four sides which are equilateral triangles. The angles formed between the edge of the base and the equilateral side is 90°, thus, we can clearly apply the pythagorean theorem.
