$7.5 * 10^9 = $7.5 * 1,000,000,000 = $7,500,000,000
It is seven billion, five-hundred million dollars.
Given
Ravi has $445 in his savings account.
He wants to save at least $795.
Write and solve an inequality to determine how much more money Ravi must save to reach his goal.
To proof
As given
amount of money in dollars Ravi must save to reach his goal be = d
Ravi has in his savings account = $445
He wants to save at least $795
than the inequality become in the form
thus $350 Ravi must save to reach his goal.
Hence proved
Option B
The thickness of each washer is 0.083 inches
<em><u>Solution:</u></em>
Given that Bryce buys 9 bolts and he buys 9 washers to place onto the bolts
He puts the washers he bought in a stack that has a height of 0.747 inches
To find: thickness of each washer
From given information,
Number of washers bought = 9
Height of stack = 0.747 inches
Thus, thickness of each washer can be found by dividing height of stack by number of washers bought
Substituting the values we get,
Thus thickness of each washer is 0.083 inches
