Answer:
b=130°
Step-by-step explanation:
The relationship between these two angles is about the fact that they are supplementary
i.e their sum is 180°
The <em>correct answer</em> is:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
Explanation:
To write a number in expanded form, we use place values.
4 is in the hundreds place; this makes its value 400.
1 is in the tens place; this makes its value 10.
2 is in the ones place; this makes its value 2.
6 is in the tenths place; this makes its value 0.6.
3 is in the hundredths place; this makes its value 0.03.
8 is in the thousandths place; this makes its value 0.008.
To write this together, we find the sum:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
Answer:
I think these are the right answers. The answer to one is 32. The answer to two is 38.
1: 2[18-(5+3^2)/7]
2[18-(5+9)/7]
2[18-14/7]
2[18-2]
2 times 16 = 32
2: I used a calculator for this one.
Answer:
width = 18 cm
Step-by-step explanation:
perimeter of rectangle = 2(length + width)
then:
90 = 2(27+w)
90/2 = 27+w
w = width
45 = 27+w
45 - 27 = w
18 = w
Check:
90 = 2(27+18)
90 =2*45 =
Answer:
You would usually use 3.14
Step-by-step explanation:
It kind of depends on where you are using it. In an equation, pi would be used as 3.14 and the answer would be approximated. To write it anywhere else (I dont know where else you would though), you would do the pi symbol. I hope this helps.
