PEMDAS is the correct order of operations... parentheses, exponents, multiplication, division, addition, and subtraction.
Let's do Holly first
6 x (24/2)^2= first the parentheses
6 x (12)^2 = now exponents
6 x 144 = and multiplication
864
Now Jim
6 x 24 / 2^2 = exponents first
6 x 24 / 4 = next multiplication
144 / 4 = now division
36
So, Jim's expression is 828 less than the other expression
(864 - 36 = 828)
.16 is equivalent to the fraction 4/25
Answer:
x*8 + y*14 ≥ 20
Step-by-step explanation:
We know that:
A batch of brownies makes 8 servings.
A pie makes 14 servings.
He wants to make, at least, 20 servings.
Then if he makes x batches of brownies, he will get x times 8 servings.
If he makes y pies, he will get y times 14 servings.
Adding that, he will get a total of:
x*8 + y*14 servings
And because he wants to make at least 20 servings (he can make 20 or more)
The inequality will be:
x*8 + y*14 ≥ 20
Where the "≥" symbol means that the expression at the left is greater than or equal to the expression of the right
Answer: triangles are similar.
Step-by-step explanation:
Givn : OK = 3, OJ = 30, KN = 1, JM = 3#
Angle O is common in both the triangles.
Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.
That means
That means the three angles of triangle OKJ are equal to the corresponding three angles of triangle ONM.
Hence the to triangles are similar.
11:45 ---> 01:20
11:45 + (00:15 + 01:00 + 00:20)
= 01:20
So your answer is:
01:35 which is 1 hr, 35 mins.
