Answer: The solution would be C
Step-by-step explanation:
If we multiply 40 candy bars by $2.50 we would get the answer of $100 because that is how much she made from selling candy bars. . Then we would have to subtract that answer by $25 because that is how much the box cost. $100 minus $25 is equal to $75. So the answer would be option C

1/5 + 3/15
Answers should be in format for example 5/2 or 2/5. No decimals or mixed numbers
Work Shown:
1/5 = 3/15 after multiplying top and bottom by 3
1/5 + 3/15 = 3/15 + 3/15 = (3+3)/15 = 6/15
Reduce that result to get
6/15 = (2*3)/(5*3) = 2/5
So 6/15 reduces to 2/5
Overall,
1/5 + 3/15 = 2/5

Manuel noticed that his cellphone bill reflected a monthly fee of
$40 as well as a charge for $0.05 per minute on the phone.
Manuel lost his August phone bill, but remembers that he paid
$48 total for the month. How many minutes did he spend on the
phone in August? Fill in the blank with a number only.
Answer:
He spent on 16 minutes
Step-by-step explanation:
Given
[tex]Base\ Amount = \$40[/tex]
[tex]Charge = \$0.5[/tex] per minute
[tex]Total = \$48[/tex]
Required
Determine the number of minutes
Let the number of minutes be n
If 1 minute costs $0.5
n minutes would cost $0.5n
The relationship between the given parameters is
[tex]Total = Base\ Amount + Charges[/tex]
Substitute values for each of the above
[tex]48 = 40 + 0.5n[/tex]
Solve for 0.5n
[tex]0.5n = 48 - 40[/tex]
[tex]0.5n = 8[/tex]
Solve for n
[tex]n = 8/0.5[/tex]
[tex]n = 16[/tex]
He spent on 16 minutes

find two consecutive odd integers whose sum is 16
Answer:
7, 9
Step-by-step explanation:
The average of the two is the even integer between them:
average = sum/2 = 16/2 = 8
The two odd integers are 7 and 9.
_____
In this case, the divisor for the average is 2, because there are 2 integers in the sum.

0.005 is 1/10 of 0.05.
Answer:
True.
Step-by-step explanation:
Let 0.005 is x times of 0.05. It can be solved as follows :
0.005 = 0.05x
Dividing both sides by 0.05,
[tex]\dfrac{0.005 }{0.05}=\dfrac{0.05}{0.05}x\\\\x=\dfrac{0.005 }{0.05}\\\\x=0.1\\\\\text{or}\\\\x=\dfrac{1}{10}[/tex]
So, 0.005 is 1/10 of 0.05. Hence, the given statement is true.
Abbys aunt is having a baby. Abby buys ribbon at the craft store to decorate a baby blanket. She buys 12.5 feet of green ribbon and 13.5 feet of polkadot ribbon. the green ribbon cost $.70 per foot in the polkadot ribbon cost $1.10 per foot. How much money does Abby spend on ribbon in all?
Answer:
$23.60
Explanation:
you can make an equation out of the information provided! it will look something like:
12.5(.7)+13.5(1.1)
(12.5 is the amount of green ribbon and .7 is the cost per foot, so you would multiply them to find the total cost of the ribbon. do the same thing for the polka dot ribbon; 13.5 feet times 1.1, the cost per foot, will give u the total cost of polka dot ribbon. then, add them together for the total cost of both ribbons!!)
12.5×.7=8.75
13.5×1.1=14.85
8.75+11.85=23.6, or $23.60!!
What are the solutions to (x + 7)2 = 81?
O A. -74 and 88
O B-2 and 16
O C. -88 and 74
O D. -16 and 2
Please answer as fast as possibleee !!
Think of the binomial squared as its own squared term.
Since the squared term is isolated, we can take the square root of both sides.
On the left, the square root removes the square and we have x + 7.
On the right, the square root of 81 is ± 9.
*Always use plus or minus when taking square root of both sides*
So we have x + 7 = ± 9.
Now, split things up into two separate equations.
Solving each equation from here, we find that x = -2 or x = 16.
We can write this as {-2, 16}.
The solutions to the equation [tex](x + 7)^2 = 81[/tex] are x = 2 and x = -16.
The correct option is D.
To find the solutions to the equation [tex](x + 7)^2 = 81[/tex] , we can start by taking the square root of both sides of the equation. However, since we have a squared term, we need to consider both the positive and negative square roots.
Taking the square root of both sides, we have:
[tex]x + 7 = \pm \sqrt{81}[/tex]
Simplifying the right side, we get:
x + 7 = ±9
Now, we can solve for x by subtracting 7 from both sides:
x = -7 ± 9
This gives us two possible solutions:
x = -7 + 9 = 2
x = -7 - 9 = -16
Hence, the correct answer is option D: -16 and 2.

Find the sample standard deviation:
2 6 15 9 11 22 1 4 8 19
A) 6.3.
B) 7.1.
C) 6.8.
D) 2.1
Answer:
B. 7.1Step-by-step explanation:
Given the sample data 2 6 15 9 11 22 1 4 8 19, before we can get the standard deviation, we need to first calculate the mean.
mean = 2 +6 +15 +9 +11 +22 +1 +4 +8 +19/10
mean = 97/10
mean = 9.7
Standard deviation for ungrouped data is expressed using the formula;
[tex]S = \sqrt{ \dfrac{\sum(x-\overline x)^2}{n-1} }[/tex]
[tex]\overline x \ is\ the \ mean\\n \ is \ sample \ size[/tex]
[tex]S = \sqrt{\frac{(2-9.7)^2+(6-9.7)^2+(15-9.7)^2+(9-9.7)^2+(11-9.7)^2+(22-9.7)^2+(1-9.7)^2+(4-9.7)^2+(8-9.7)^2+(19-9.7)^2}{10-1} }\\ S = \sqrt{\frac{(-7.7)^2+(-3.7)^2+(5.3)^2+(-0.7)^2+(1.3)^2+(12.3)^2+(-8.7)^2+(-5.7)^2+(-1.7)^2+(9.3)^2}{10-1} }\\\\S = \sqrt{\dfrac{59.29+13.69+28.09+0.49+1.69+151.29+75.69+32.49+2.89+86.49}{10-1} }\\\\\\S = \sqrt{\dfrac{452.1}{9} }\\\\S = \sqrt{50.23}\\ \\S = 7.08\\\\S \approx 7.1[/tex]
Hence the standard deviation of the sample data is 7.1

x = # of days
y = total calories
Simba = 1000 + 140x = y
Cuddles = 2650 - 190x = y
Let's set both of these equations equal to each other
1000 + 140x = 2650 - 190x
Add 190x to both sides and subtract 1000 from both sides.
330x = 1650
Divide each side by 330
x = 5
After 5 days, they will be consuming the same amount of calories.
To find out how many calories they will be consuming, let's plug 5 into our Simba equation.
1000 + 140(5) = y
Multiply 140 by 5
1000 + 700 = y
Simplify
1700 = y
They will be consuming 1,700 calories each day.
