When approaching an equation such as this, it is important to consider the acronym PEMDAS, which stands for parenthesis, exponents, multiplication, division, addition and subtraction. According to these rules, as there are no numbers in brackets, the first thing you need to do is to add the exponent 2 to 8x.

12345 [234]

Answer: 389

Step-by-step explanation: well if there is lollipops for $2.50 each and they sold thrice as many lollipops then they have sold 7.5 of the lollipops and if you sell thrice of the cookies then that will be 31.5 and if you add 7.5 and 31.5 that will be 39 so the real answer is 389.

A lawn sprinkler sprays water 4 feet in all direction as it rotates.
Ber [7]

Answer:

50.24 ft^2

Step-by-step explanation:

The radius of the circle in which the lawn sprinkler sprays water is 4 feet.

The formula to find the area of a circle is \pi r^2, where r = radius and π, in this case, is 3.14.

  • 3.14 × 4^2
  • 3.14 × 16
  • 50.24 ft^2

Therefore, the answer is 50.24 ft².

What formula do i use when it tells me to find the area with a given circumference? If you know please give an example as well,
liberstina [14]

Answer:

Step-by-step explanation:

A = C^2 / 4 x pi

so if the circumfernce was 10 you would square it to make it 100 and then you would do 4 x pi to get 12.57 ( rounded).

you would then just divide 100 by 12.57 = 7.96 ( rounded)

hope it helped

Determine the slope from the given graph below:
Greeley [361]

Step-by-step explanation:

the slope is the ratio of "y coordinate difference / x coordinate difference".

so, let's find 2 good points (I mean by that with integer coordinates). I see e.g.

(-1, -1) and (0, -7)

x changes by +1 (from -1 to 0).

y changes by -6 (from -1 to -7).

so, the slope is -6/1 = -6.

D is the right answer.
