Answer:

$50.29

Step-by-step explanation:

First, find the total without tax by adding the two items together

35+12=47

Next, find the sales tax

Convert 7% to a decimal

7/100=0.07

Multiply the decimal by the total

47*0.07=3.29

Lastly, add the tax and the total without tax

47+3.29=50.29

So, the total with tax is $50.29

Hope this helps! :)

Answer:

x² - 3x - 10 = (x - 5) (x + 2)

x² - 3x - 18 = (x + 3) (x - 6)

Step-by-step explanation:

<u>x² - 3x - 10</u>

x² + 2x - 5x - 10

x(x + 2) - 5(x + 2)

(x - 5) (x + 2)

<u>x² - 3x - 18</u>

x² - 6x + 3x - 18

x(x - 6) + 3(x - 6)

(x + 3) (x - 6)

A telecommunication company has 7 satellites, two of which are sending a week signal. If two are picked at random without replac
Setler [38]
2/7 is the probability that the first satellite sends a weak signal. That leaves 6, one of which sends a weak signal. So the probability that the second also sends a weak signal is 1/6. Combine these and we get 2/7×1/6=1/21.

A father is 25 years older than his son. 10 years ago, he was six times as old his son. What are their present ages?​
RoseWind [281]

Answer:

Present age of son = 15 years

& Present age of father = 40 years

Step-by-step explanation:

  • Let the son's present age be x years

  • -> Father's present age = (x + 25) years

  • 10 years ago:
  • Son's age = (x - 10) years

  • Father's age = (x +25 -10) = (x +15) years

  • It is given that: 10 years ago father was six times as old as his son

  • -> x + 15 = 6(x - 10)

  • -> x + 15 = 6x - 60

  • -> x- 6x = - 60 -15

  • -> -5x = - 75

  • -> x = -75/(-5)

  • -> x = 15

  • -> x + 25 = 15 + 25 = 40

  • -> Present age of son = 15 years

  • & Present age of father = 40 years.

Jack goes to a store and selects 2
Sav [38]

For questions like this just multiply the prices by how many they're buying and add all the numbers up and subtract by how much they have to begin with.

Example:

$34.99×2=$69.98

$16.50×3=$49.50

$3.75×4=$15

$69.98+$49.50+$15=$134.48

$134.48-$125=$9.48
