Answer:
for the box n=40, the answer is 80 = 2 x n
for the box n=10, the answer is 8 x n = 80
for the box n = 8, the answer is n x 2 = 16 and 40 = n x 5
Step-by-step explanation:
for the box with 40, 2x40=80
for the box with 10, 10x8=80
for the last box, 2x8=16 and 5x8=40
Answer:
AB = 7 / cos 41° = 7/(0.7547) = 9.26
CA = 7×tan 41° = 7×0.8693 = 6.08
Answer:
0.00
Step-by-step explanation:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
Answer:
Kim is 24 and her sister is 12.
Step-by-step explanation:
a) Xx2+X
I used the variable X because that represents Kim's sisters age, which you need to know in order to find out Kim's age. To get Kim's sisters age use a guess and check table or pick numbers until you get to the correct answer.
b) 12x2=24
24+12=36
My solution is Kim is 24 and her sister is 12.
