64. 80x4=320. 80 is a b average. 320-252=68. 252 is the total of her current grades.
Answer:
3
Step-by-step explanation:
Note that
(
)² = a, for example
(
)² = 10² = 100 ← value inside the radical
Thus
(
)² = 3
24, because area means to multipy and it gives 6 ins. and 4 ins. so 6x4 is 24. Hope I was helpful.
Answer:
The chance of rolling a number greater than 4 (a 5 and 6) is 2/6 = 1/3 after simplification. The probability it WON'T happen is 1 - 1/3 = 2/3.
The ratio of against to for is 2/3:1/3
You can further simplify this ratio by multiplying each side by 3 and yielding
2:1.
The chance of it not happening is twice as likely as it is to roll a number greater than 4
If you would like to order the following numbers from least to greatest, you can do this using the following steps:
<span>- 40, 1250, - 6.44, 0.2
</span>- 40 < - 6.44 < 0.2 < 1250
The correct result would be <span>- 40 < - 6.44 < 0.2 < 1250.</span>
