Marna is playing a game where you score -5 points each time you guess the correct answer. the goal is to get the lowest score. to win the game, marna must have a score of less than -80 points. how many correct answers does mama need to win the game?create an inequality for this
Answers
Answer: Marna has to answer more than 16 answers to win the game.
Step-by-step explanation:
Le 'x' be the number of correct answers.
If Marna is getting -5 points each time she guess the correct answer.
Then the total points she get after x correct answers= -5x
If to win the game, Marna must have a score of less than -80 points.
⇒
If we multiply (-1) on both sides the inequality will reverse
Divide both sides by 5, we get
Marna has to answer more than 16 answers to win the game.

Answers
1. 10^2+b^2=17^2
So 100+b^2=289
b^2=189
b=
b=13 3/4
The dimensions are 10 by 13 3/4
2. 5^2+b^2=13^2
So 25+b^2=169
b^2=144
b=12
The ladder reaches 12 feet off the ground

Final answer:
The equation to find the value of R depends on the context. For resistors in series, the equation is R = R₁ + R₂ + R₃ + ..., while for parallel it is 1/R = 1/R₁+1/R₂ + 1/R₃ +.... In power calculations, the equation R = V²/P can be used.
Explanation:
To find the value of R, we can use various mathematical formulas depending on the context. For instance, in the context of circuits, the total equivalent resistance (R) of resistors in series is given by the equation R = R₁ + R₂ + R₃ + .... While for resistors in parallel, the equation is 1/R = 1/R₁+1/R₂ + 1/R₃ +....
In terms of power, the equation P = V²/R can be rearranged to R = V²/P to find the value of R. In case of calculations involving thermal resistance, the equations can be more complex and might require the use of other variables.

Answer:
x = 11, x = -11
Step-by-step explanation:
I know this is kind of late but the two previous answers were wrong.
We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:
√x² = √121
x = √121
You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.
Answer:
x=11
