The student subtracted each side by 28, which is wrong because if u want to cancel -28, you need to add 28 to both sides. The correct answer is 403.
I need brainliest answer pls
Let the width = x
=>length = 2x-1
91= x(2x-1)=2x^2-x
2x^2-x-91=0
=(2x+13)(x-7)
=> x=-13/2=> no
=>x= 7 cm
Answer:
46
Step-by-step explanation:
-Let b be the constant in the linear equation.
#The linear equation can be expressed as:
Substitute the values in the equation to find b:
We know have the constant value b=-14, substitute the values of b and x in the p(x) function:
Hence, the profit when selling price is $0.60 is $46
#From our calculations, it's evident that the cookies production has a very high fixed cost which can only be offset by raisng the selling price or the number of units sold at any given time.
Answer:
D
Step-by-step explanation:
Probability is, by definition, a number between 0 and 1, which can be expressed as a fraction or a percentage. For example, the odds of getting heads if you throw a fair coin are 50%, or ½. The odds of not getting heads are 1-½=½.
If the probability of something happening is 1, it means that that thing will happen for sure. Likewise, if the probability of an event is 0, it means that the event will never happen.
You can therefore easily understand that it doesn't make sense to have a probability greater than 1, as we have in choice D.
Answer:
42 degrees
Step-by-step explanation:
angle is x
supplement is 180-x
x+96=180-x, since it is 96 less than its supplement
2x=84
x=42
180-x=138
The angle is 42 degrees.
