Answer:
9.407x10-11
Step-by-step explanation:
8.18(9.407x(10)−11)10−6(1.15(9.407x(10)−11)10−5)
8.18(9.407x(10)−11)10−6(1.15(9.407x(10)−11)10−5)
Hello there! A. 3.75 hours is your answer.
Okay, so lets start by finding the unit rate. To find the unit rate, we can use this formula: total ÷ time = unit rate.
total (72 cookies) ÷ time (2.5 hours) = unit rate. (how many cookies she can decorate and bake in an hour)
72 ÷ 2.5 = 28.8 cookies an hour
Now that we have this information, replace the 180 cookies in for the total number and use algebra to solve.
180 cookies ÷ x time = 28.8
Since 180 is a little more than 2 times 72, A would best fit since 3.75 is much closer to 2.5 than the other options. To check this, we can place 3.75 in for x in 180 ÷ x = 28.8.
180 ÷ 3.75 = 28.8.
So, this is your correct answer.
A = (1/2)(x)(y)
Let x = diagonal 1
Let y = diagonal 2
The product of xy = 144.
This means that x = 12 and y = 12.
So, 12 • 12 = 144
Each diagonal is 12 feet.
Prove:
72 feet = (1/2)(12)(12) feet
72 feet = (1/2)(144) feet
72 feet = 72 feet
Answer: 130
Step-by-step explanation:
--> first solve sqr-->2-64/4+144
-->perform division next as per DMAS rule-->64÷4=16--> 2-16+144
--> now perform addition and subtraction-->2-16-14--> -14+144= 130
