Answer:
I will first divide the shape into two rectangles. first rectangle area would be 60x15=900mm^2. next rectangle is 20x30=600mm^2. 900+600=1500mm^2. the area is 1500mm^2, which is answer D

Answer:
Domain of y=![\sqrt[4]{x-1}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx-1%7D)
: is x>=1
Interval notation: [1,∞)
Step-by-step explanation:
We have y=
1) The domain of a function is the set of x values for which the function is real and defined.
2) So, x-1 should be positive means x-1>=0, because fourth root of any negative value would be a complex number and not a real number.
3) Now we solve the inequality x-1>=0
4) Adding 1 to both sides of the inequality we get,
x-1+1 > = 0+1
5) Cancel out -1 and +1 from the left side
6) We get x>=1
It concludes that for the domain of the given function, the x value must be greater than or equal to 1
Answer:
49 third graders
Step-by-step explanation:
From the question:
The music teacher receives 9 boxes of recorders and there are six recorders in each box
The total number of recorders the teacher received =
1 box = 6 recorders
9 boxes = x
Cross Multiply
x = 9 × 6 recorders
x = 54 recorders.
She hands them out to third graders and has 5recorders left .
How many third graders received a recorder?
The amount of recorders shared =
54 recorders - 5 recorders
= 49 recorders
If 1 recorders was given to a third grader,
Therefore, the amount of third graders that received a recorder is 49 third graders
Answer: x = 3
Step-by-step explanation:
5x - 1 + 14 - original equation
5x = 15 - add 1 to both sides
x = 3 - divide both sides by 5
