Roberta bought 9/10 pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5 pound bags can Roberta fill? Does she have any left over?
Answer:
2 pound bags and have a remeinder of 1/10
Step-by-step explanation:
Answer:
She can fill 2 bags for her lunch and will have 1/10 pound left.
Step-by-step explanation:
It is easier if there is a common denominator, so I made the 2/5 into 4/10, so it is the same as 9/10 pound she bought.
4/10 is one bag, and if you double that, it is 8/10 pounds used. This is two bags of raisins for her lunch.
9/10 - 8/10 leaves 1/10 pound remaining, and not in a bag.

Answer:
false
Step-by-step explanation:
whole numbers don't include negative numbers / integers
Answer:
the answer would be false
Step-by-step explanation:
This is because whole numbers are nothing but a set of positive integers which do not contain fractions and decimal values, but starts from zero. The negative integers like -5, -4 … are also not considered as whole numbers. They are represented as {0, 1, 2, 3…}.

Answer:
The correct answer is A, 14%.
Step-by-step explanation:
All you have to do is take the 30% chance of you HAVING to stop at the first light and find the chance that you won't have to stop at the first light, which is 70%, or .7. Then you take the chance of having to stop at the second light which is 80%, and find the probability of NOT having to stop there, which is 20%, or .2. Then you multiply the probabilities of not having to stop, which equals .14.

if Richard worked for 7 dollars and made 9 dollars and hour how much would he make?
Answer:
$63
Step-by-step explanation:
I believe you meant Richard worked for 7 hours and made $9 per hour.
In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.
7 hours x 9 dollars/hour = $63Therefore, Richard earned $63 for his 7-hour work.
Additional Information
Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.
10 hours x 9 dollars/hour = $9058.74% as a decimal due today

Jack and Jill each go out shopping.
Jack spends 1/3 of his money.
Jill spends 40% of her money.
Frank says Jack spent more because 1 /3 is greater than 40%.
Alice says you cannot tell who spent more.
Who do you agree with, Frank or Alice? Explain why.
I agree with Alice because you do not know how much money Jill and Jack had before they went shopping. If they had the same amount of money Jill would have spent more because 40 percent is greater than 1/3.

Which is an equation in point slope form for the given point and slope? Point: (-3,7) Slope: 4
Answer:
y-7=4x(x+3)
Step-by-step explanation:
(The 4x is 4 times ...)
Answer:
[tex]y -7 = 4(x+3)[/tex]
Step-by-step explanation:
Point-slope form is in the format of [tex]y-y_1 = m (x-x_1)[/tex]. When knowing a line's slope and a point it passes through, you can write an equation in that format. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] must be substituted for with real values.
The [tex]m[/tex] represents the slope, thus substitute 4 for [tex]m[/tex]. [tex]x_1[/tex] represents the x-value of one point the line passes through, while [tex]y_1[/tex] represents that same point's y-value. The line passes through (-3, 7), so substitute -3 for [tex]x_1[/tex] and 7 for [tex]y_1[/tex]. This gives the following answer and equation:
[tex]y-(7) = 4(x-(-3))\\y -7 = 4(x+3)[/tex]

Function c is defined by the equation c(n)=50+4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. What is the inverse function.
Answer:
(x - 50 / 4) = y
Step-by-step explanation:
On photo
To find the inverse function, you will have to write n in terms of c (which means number of visits as function of monthly cost).
The inverse function would be:
[tex]n = \dfrac{c-50}{4}[/tex]
Given that:c(n) = 50 + 4nc is monthly cost in dollars, of visiting a gym.n is the number of visits.To find:Inverse function of given function.
What is inverse function and when is it possible to find such function?The inverse function of f is a function of f which can remove the effect of f on its input.
Inverse is only possible if the function f is bijective (one to one correspondence, which means one input to one output uniquely and one output is connected to only one input by mapping f)
Since the given function is a linear function and not a vertical line, thus, one input n uniquely maps to one output cost and one cost uniquely is obtained by one and only one value of n.
Finding the inverse function of c(n) = 50 + 4n:[tex]cost = 50 + 4n\\ 4n = cost - 50\\\\ n = \dfrac{\text{c - 50}}{4} \text{\: (assuming cost to be denoted by c)}[/tex]
Thus, we have the inverse function of given function as:
[tex]n = \dfrac{c-50}{4}[/tex]
