impatient much?
3/4 * 3/4 = 9/16
thx babe
Thx but......I feel like a third wheel now ;-;
Oliver needs to save at least $1500 to buy a computer. He has already saved $650. How much more does he need to save? Write and solve an inequality.
Let x be the amount that Oliver still needs to save.
According to the problem,
x + 650 ≥ 1500
Solving for x,
x ≥ 1500 - 650
x ≥ 850
Therefore, Oliver still needs to save at least $850 more to buy a computer.
On a number line, what is the distance between -57 and 13?
To find the distance between -57 and 13, we need to subtract the smaller number from the larger number and take the absolute value:
Distance = |13 - (-57)|
Distance = |13 + 57|
Distance = |70|
Distance = 70
Therefore, the distance between -57 and 13 on the number line is 70 units.
On a given morning the temperature was 71°F. The temperature dropped 5°F and then rose 8°F. How much does the temperature need to rise or fall to return to the initial temperature of 71°F?
The temperature dropped 5°F and then rose 8°F, which means the temperature changed by a net amount of +8°F - 5°F = 3°F.
To return to the original temperature of 71°F, we need to undo the net change of 3°F. Since the temperature initially dropped by 5°F, and we need to undo this change, the temperature needs to rise by 5°F. This means that the temperature still needs to rise by an additional 3°F - 5°F = -2°F to return to the initial temperature of 71°F.
However, since the question asks for how much the temperature needs to "rise or fall", we need to take the absolute value of -2°F, which is 2°F.
Therefore, the temperature needs to either rise by 2°F or fall by 2°F to return to the initial temperature of 71°F after dropping by 5°F and then rising by 8°F.
To find out how much of the whole cake Raj ate, we need to multiply the fractions.
Step 1: Start with the fraction of the cake Raj was given: 3/4.
Step 2: Multiply 3/4 by 3/4 to find out how much of THAT cake Raj ate.
3/4 * 3/4 = (3 * 3) / (4 * 4) = 9/16.
So Raj ate 9/16 of the whole cake.
