Answer:
Your answer is 61.
Step-by-step explanation:
Simple enough! We simply round up each cost to the nearest whole dollar. $6.50 can be rounded to $7, $15.75 can be rounded up to $16, $2.25 can be rounded up to $3 (Note we're rounding up, in normal rounding we would round down to $2). Finally, $7.25 can be rounded up to $8.
Next comes simple algebra,
Therfore, your overestimate of the cost would be 61.
Answer:
2.1275 is 2.12747677748 rounded to the nearest ten-thousandth.
Step-by-step explanation:
Since the hundred-thousandth place is 5 or above, we would round the ten-thousandths place up. THis makes the number 2.1275.
Answer:
Option B). 10 cm
Step-by-step explanation:
Distance between center and the focus of an ellipse is given by the formula,
c² = a² - b²
where, a = length of the major axis
b = length of the minor axis
and c = distance between focus and center
If c = 6 cm, b = 8 cm,
6² = a² - 8²
a² = 6² + 8²
a² = 36 + 64
a² = 100
a = 10 cm
Therefore, length of the major axis is 10 cm.
Option (B) is the answer.

Answer:
2/3
Step-by-step explanation:
If 2/3 · x= 4/9 then 4/9 ÷ 2/3= x
KCF (Keep Change Flip)
Keep 4/9
4/9 ÷ 2/3
Change from division to multiplication
4/9 · 2/3
Flip 2/3 to 3/2
4/9 · 3/2
Multiply 4 · 3= 12
Multiply 9 · 2= 18
Simplify
12 ÷ 6= 2
18 ÷ 6= 3
x=2/3
