Answer:
d. x-700=35
Step-by-step explanation:
The statement says that the variations will stay within a range of +5%, so the resistance can be increased by 5% of 700 ohms. To find the highest resistance that can be achieved, you can use the formula:
x = 700 + (700 * 5%) = 700 + 35 = 735 ohms
To find the lowest resistance that can be achieved, you can subtract the same percentage (5%) of 700 ohms:
x = 700 - (700 * 5%) = 700 - 35 = 665 ohms
So the lowest and highest resistance that can be achieved are 665 ohms and 735 ohms respectively.
Jordan has 8 coins in his pocket. They are a combination of dimes and quarters. If they total to $1.25, how many of each coin does he have
Answer:
q=quarters, d=dimes
q+d=8
.25q+.1d=1.25
Let's set the first equation to equal d.
d=8-q
.25q+.1(8-q)=1.25
Distribute.
.25q+.8-.1q=1.25
Combine Like Terms
.15q+.8=1.25
Subtract .8
.15q=.45
Divide by .15
q=3
Now, let's solve for d in the first equation.
d+3=8
Subtract 3, and you get d=5
So, there are 5 dimes and 3 quarters in Maribel's pocket.
Check: .25(3)+.1(5)=1.25
.75+.5=1.25
1.25=1.25 which is true.
Pls mark me as brainliest!Jordan has 3 quarters and 5 dimes in his pocket that total to $1.25.
Explanation:Let's assume Jordan has x number of quarters and 8 - x number of dimes in his pocket.
Each quarter is worth 25 cents, so the value of the quarters is 25x cents.
Each dime is worth 10 cents, so the value of the dimes is 10(8-x) cents.
The sum of the values of the quarters and dimes should be equal to $1.25, which is 125 cents. So, we can set up the equation: 25x + 10(8-x) = 125.
Simplifying the equation, we get 25x + 80 - 10x = 125. Combining like terms, 15x + 80 = 125. Subtracting 80 from both sides, 15x = 45. Finally, dividing both sides by 15, we find x = 3.
Therefore, Jordan has 3 quarters and 8 - 3 = 5 dimes in his pocket.

Alec's parents give him x dollars per month for his allowance. However, since his birthday is in February, he gets an extra 20% bonus that month. The allowance in February can be represented by the expression x + 0.2x because Alec will get the regular allowance of x dollars plus an extra 20% bonus which is equal to 0.2x dollars.
x + 0.2x = Alec's allowance in February
The expression 1.2x is not correct because it represents Alec's allowance multiplied by 1.2 which is not the same as the allowance plus the bonus.
So the correct answer is x + 0.2x.
