400+30+7+.04. That is what it would be because you are basically adding the place values. The 4 is basically 400, the 3 is basically 30, the 7 is basically just 7, and the .04 is also just .04. For exams: the 3 is in the hundreds place do it would be 300. Get it?
I believe this one is C but none of the equations seemed to work for me when I imputes them into a graphing calculator. Not sure what I did wrong or if maybe the question is wrong. Hope this helps!
Answer:
x = 33 degrees
Step-by-step explanation:
Angle ABC = BDA because they are alternate interior angles.
So:
Angle BDA = 42 degrees
x = 180 - 105 - 42
x = 33 degrees
Answer:
4.8 x 10^9
Step-by-step explanation:
E9 is 10 raised to the power of 9
Scientific notation requires you to write a number from 1 to 10 then multiply it by 10 raised to a number x.
In this case:
4.8E9 = 4,800,000,000
Number between 1 and 10 = 4.8
Number of zeroes = 8 but because you have to multiply 4.8 times 10 to get 48 the answer is 4.8 x 10^9... so one extra 10... 1+8=9
Hope you understand
Answer:
432 square feet
Step-by-step explanation:
We know perimeter of rectangle is 2(length + width)
we already know that length is 8 yards
and perimeter is 84 feet
we need to find width first
then
we find area of garden by using formula
area of rectangle = length * width
first we need to convert yards into feet as perimeter is in yards
1 yard = 3 feet
8 yards = 3*8 feet = 24 feet
now we plug value of length and perimeter in formula
perimeter = 2(length + width)
84 = 2(24 + width)
84/2 = 24 + width
=> 42 = 24 + width
=> width = 42 - 24 = 18
Thus, width of garden is 18 feet
now
area of Jordan's garden = length * width = 24* 18 feet square
area of Jordan's garden = 432 square feet
