Suppose a calculator is on sale at a 15% discount if it normally sells for 2999 what is the sale price

1 answer:

5 0

You would turn 15% into a decimal. Which would be .15, and then do .15 times $29.99 which is $29.84. Then you would subtract the $29.99 minus the $29.84

In the game of roulette, a player can place a $5 bet on the number 3 and have a startfraction 1 over 38 endfraction probabilit

Misha Larkins [42]

The expected value per game is -0.26. Over 1000 games, you can expect to lose $263.16.

To find the expected value, we multiply the probability of winning by the amount of winnings, the probability of losing by the amount of loss, and adding those together.

We have a 1/38 chance of winning; 1/38(175) = $4.61. We also have a 37/38 chance of losing; 37/38(5) = $4.87.

$4.61-$4.87 = -$0.26 (rounded)

To five decimal places, our answer is -0.26136; multiplied by 1000 games, this is $261.36 lost.

Best answer gets brainliest

Luden [163]

K= -3

3y = x+6 can be rewritten as y = 1/3x + 2
a perpendicular slope is the opposite reciprocal of the original slope
so instead of 1/3 it would be -3
therefore. k must equal -3 to be perpendicular to 3y = x+6

If line segment BH = 3, line segment BF = 10, line segment GH= 2, find HD 15 11 10.5 ?

pav-90 [236]

HD = 10.5

Step-by-step explanation:

Given BH = 3, GH = 2, BF = 10

Step 1: To find HF:

HF = BF – BH

HF = 10 – 3

HF = 7

Step 2: To find HD:

We know that if two chords intersects inside a circle, the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.

⇒ GH × HD = BH × HF

⇒ 2 × HD = 3 × 7

⇒ HD = 10.5

Hence, the value of HD = 10.5.

Complete the equation: x^2+8x + _=(_)^2

pentagon [3]

Answer:

x^2+8x+16=(x-4)^2

EXPLANATION:

(a+b)^2=a2+2.a.b+b2

we have to break the middle term in 2ab here a is x then 2xb=8x, => b=4, but value of a and b to get the required equation!

horrorfan [7]

<h3>Answer:</h3>

4, 8, 8

<h3>Step-by-step explanation:</h3>

At each node, three faces meet. One is square (4 sides); the other two are octagons (8 sides). Hence the tiling can be named with three numbers: 4, 8, 8.
