Pocahontas wants to buy a tennis racket that is 70% off. The original price is $156.33. What is amount of discount (nearest penny)?
What is the sale price (nearest penny) please show your work

Answers

1. You could plug this into the calculator as either 70% of 156.33 or 0.7 × 156.33, but either way you know the discount is going to be $109.43

2. We got the discount, so all you have to do is subtract it from the original. 156.33 - 109.43 = $46.90 which is the sale price! I hope this helps

What is the slope of a line that passes through the origin and the point (6, 3)

Answers

Answer:

Slope = 1/2

Step-by-step explanation:

Formula for getting slope using 2 points...

(y2 - y1) / (x2 - x1)

= (3 - 0) / (6 - 0)

= 3 / 6

= 1/2

So...

Slope is 1/2

Hope this helps :)

Let me know if there are any mistakes!!

Answer:  The slope is   1/2

Step-by-step explanation:

When a line passes through the origin the equation of the line will be represented in the form    y= kx   where k is the slope.

To to find k you will need to divide both sides by x.

y = kx

y/x = kx/x

  k = y/x  

This means that to find k, you will need to divide the y coordinate of the point by the x coordinate.  

  k = 3/6

K = 1/2

Over here, we have exponential growth.

So we have 50 bacteria

Every 30 minutes, it doubles in size

In 120 minutes, there are four 30 minutes.

Okay so for a pack of 12 confetti eggs, you pay $2.88. to find the unit price, or price for 1 egg, you just take 2.88 divided by 12 (which i already did) and you get 0.24. so the price for 1 confetti egg is $0.24 or 24 cents.

James reads 520 words in 2 minutes. Luke reads 960 words in 5 minutes. All we need to find out is how many words can they read in 1 minute? All ewe do is take 520 divided by 2, and you get 260. Then you take 960 divided by 5, and you get 192. so the rates they read at is 260 wpm and 192 wpm.

The ABC Book Club charges a $40 monthly fee, plus $2 per book read in that month. The Easy Book Club charges a 35$ monthly fee, plus 3$ per book read in that month. For each club, how many books must be read in 1 month for the total charges from each club to be equal.

Answers

The expression for the cost of the ABC Book Club is 2x + 40. The expression for the cost of the Easy Book Club is 3x + 35. To find when the total charge for both book clubs is equal, the two expressions must equal each other. (x = the number of books read)

2x + 40 = 3x + 35

Subtract 35 from both sides.

2x + 5 = 3x

Subtract 2x from both sides.

5 = x

So, the total charge for each club is equal when 5 books are read.

Si un hombre de 1.75m de altura proyecta una sombra de 3.50m que sombra aproximada proyecta un poste de 8.25m

Answers

Answer:

4.25 m

Step-by-step explanation:

Resolvemos esta pregunta usando la fórmula:

Altura del hombre / Sombra de un hombre = Altura del palo / Sombra del palo

Sombra del hombre = 3.50 m

Altura de un hombre = 1.75 m

Sombra del palo = 8.50 m

Altura del palo = x

Por lo tanto:

1.75 / 3.5 = x / 8.5

Cruz multiplicar

1.75 × 8.5 = 3.5 × x

14.875 = 3.5x

x = 14.875 / 3.5

x = 4.25 metros

Por tanto, la altura del palo = 4.25 m

Answer: m=−3

−40+(−2)(3m)+(−2)(1/2)=7m+−2

(−6m)+(−40+−1)=7m−2

−6m+−41=7m−2

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

 

m = -3, hope it was helpful! :)
