How much fencing does she need to buy

Mathematics

Its is surprising that no one attempted this question for over a week.

As in all geometry problems, start with a diagram (shown).

Then we realize right away that AB=sqrt(8^2+2^2)=sqrt(68)=2sqrt(17)

BC=sqrt(4^2+1^2)=sqrt(17)

The perimeter is therefore twice the sum of AB+BC=2(2sqrt(17)+sqrt(17))

2(3sqrt(17))=6 sqrt(17) We can estimate sqrt(17)=4.125, so 6sqrt(17)=24.75 which is close enough to get the correct answer choice.

Have a good day.

Decompose 8/12 in two ways with: <br> x/2 + x/2 = 8/12
LUCKY_DIMON [66]
\frac{x}{2} + \frac{x}{2} = \frac{8}{12} \\\frac{2x}{2} = \frac{2}{3} \\x = \frac{2}{3}
or
\frac{x}{2} + \frac{x}{2} = \frac{8}{12} \\\frac{x}{2} + \frac{x}{2} = \frac{2}{3} \\\frac{\frac{2}{3}}{2} + \frac{\frac{2}{3}}{2} = \frac{2}{3} \\\frac{1}{3} + \frac{1}{3} = \frac{2}{3} \\\frac{2}{3} = \frac{2}{3}

Janine has job offers at two companies. One company offers a starting salary of $28,000 with a raise of $3000 each year. The oth
Umnica [9.8K]

Answer:

  8 years

Step-by-step explanation:

The first company's offer is $8000 lower, but the raises are $1000 higher each year. It will take 8000/1000 = 8 years for the salaries to be the same.

__

If you like, you can write an equation that will tell you the same thing.

  28000 +3000y = 36000 +2000y

Subtract 28000+2000y from both sides:

  3000y -2000y = 36000 -28000

  1000y = 8000

  y = 8000/1000 = 8

Solve the equation using the zero product property -2x(5x-2)=0
anastassius [24]

Answer:

A

Step-by-step explanation:

Given

- 2x(5x - 2) = 0

Equate each factor to zero and solve for x

- 2x = 0 ⇒ x = 0

5x - 2 = 0 ⇒ 5x = 2 ⇒ x = \frac{2}{5}

Solutions are

x = 0, x = \frac{2}{5}

hoa [83]
Thanks.

Answer is 37x=720-20+20-75-76+40=609

x=609/37= 16.459 Assuming all the numbers are the same as we can see it in the equation.
