Isabelle bought 12 bottles of water at $2 each
Answers
Isabelle bought 4 bottles of water.
Here's how to solve for the number of bottles of water Isabelle bought:
Let x be the number of bottles of water Isabelle bought.
The total cost of the water bottles is 2x dollars (2 dollars per bottle * x bottles).
We know the total cost was $21, so we can set up an equation:
Total cost = Cost of water bottles + Cost of pizza
21 = 2x + 13
Now, solve for x:
Subtract 13 from both sides: 21 - 13 = 2x + 13 - 13
Simplify: 8 = 2x
Divide both sides by 2: 8 / 2 = 2x / 2
Get the final answer: x = 4
Therefore, Isabelle bought 4 bottles of water.
Complete question:
Isabelle buys bottles of water at $2 each and a large pizza at $13. The total cost was $21. How many bottles of water did Isabelle buy?
For the perfect cup of hot cocoa, Eva uses 3 scoops of hot cocoa mix, 10 miniature marshmallows, and 8 ounces of water. What is the ratio of scoops of hot cocoa to miniature marshmallows?
Answers
ratio of hot cocoa to marshmallows..
how much cocoa does she use......3 scoops
how much marshmallows does she use....10 marshmallows
so the ratio of cocoa to marshmallows is : 3/10 or 3:10 or 3 to 10 <=
The ratio of 3 scoops of hot cocoa mix to 10 miniature marshmallows and 8 ounces of water. is 3:10
What is Ratio?
A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. Similarly, the ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.
Given :-
amount of cocoa scoops = 3
amount of miniature marshmallows used = 10
We have to find out the Ratio of scoops of hot cocoa to miniature marshmallows:
First we will simplify the term if there is any
Scoops of hot cocoa / miniature marshmallows = 3/10
Since, the simplification is already been done
Thus, the ratio will be:
3 : 10
Hence, The ratio of scoops of hot cocoa to miniature marshmallows is 3:10

You made two deposits to your bank accounts this month. One deposit was $17.92, and the second deposit was $15.33. Your balance at the end of the month is $72.31, and you made no withdrawals. Which expression shows your balance at the beginning of the month?
Answers
$72.31 is the total amount AFTER ADDING TWO DEPOSITS
So, if we want to know the amount before deposits, we just need to take the total of previous two deposits

find two consecutive integers whose sum is 45
Answers
____________________________________________________
x + (x + 1) = 45 ;
in which:
"x" is the first integer (of the 2 consecutive integers) ;
"(x + 1)" is the second integer (of the 2 consecutive integers);
_______________________________________________________
We want to solve for "x";
which is the first integer (of the 2 consecutive integers);
then we can solve for the second integer (of the 2 consecutive integers);
as well;
_______________________________________________________
We have:
_______________________________________________________
x + (x + 1) = 45 ;
Rewrite as:
x + x + 1 = 45 ;
↔ 1x + 1x + 1 = 45 ;
→ 2x + 1 = 45 ;
Subtract "1" from each side of the equation;
2x + 1 −1 = 45 − 1 ;
to get:
2x = 44 ;
Divide EACH SIDE of the equation by "2" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________________________
2x / 2 = 44 / 2 ;
to get: x = 22 ;
______________________________________________
Our two consecutive integers:
x = 22 ;
(x + 1) = 22 + 1 = 23 .
______________________________________________
The two consecutive integers are: "22" and "23" .

Let us check our answer:
Are "22" and "23" consecutive integers? Yes!
Do "22" and "23" add up to "45" ? ;

Annette is surveying people in the city about their interest in a new shopping mall. She found that 180 people, or 37.5% of those surveyed do not want a new mall. How many people did Annette survey?
Answers
Answer:
480 people
Step-by-step explanation:
First you would divide 180 by 37.5,
180 divided by 37.5 = 4.8
Then you multiply 4.8 with 100
4.8 times 100 =480
Therefore, Annette surveyed 480 people
We want to find the total number of people that Annette surveyed given that we know a percentage and the number that the percentage represents.
We will find that the number of people that Annette survey is 480.
To get the solution:
Let's assume that she surveyed a total of X people.
Then we can write the equivalence:
100% = X
We know that the 37.5% is equivalent to 180 people, then we can write:
37.5% = 180
The two equations are:
100% = X
37.5% = 180
Now we can take the quotient between these two equations to get:
(100%/37.5%) = X/180
Solving for X we get:
(100%/37.5%)*180 = X = 480
So the total number of people surveyed is 480.

[tex]2,250\left(1+\frac{0.17}{12}\right)^{12t}=2,250(1+0.014)^{12t} \\ \\ =\bold{2,250(1.014)^{12t}}[/tex]
Answer:
[tex]A=2250(1.014)^{12t}[/tex] is the exponential expression.
Step-by-step explanation:
The expression which represents the balance of credit card, in dollars, after t years is
[tex]A=2250(1+\frac{0.17}{12})^{12t}[/tex]
Where rate of interest is 17% and amount spent is $2250.
Since 17% interest is the annual interest and we have done the expression in the form of monthly compounding.
So the expression will be
[tex]A=A_{0}[1+.014]^{12t}[/tex]
[tex]A=A_{0}(1.014)^{12t}[/tex]
[tex]A=2250(1.014)^{12t}[/tex]

Dawn is an avid reader and reads 30 pages every 8 days. Part A How many pages per day does Dawn read? Part B At this rate, Dawn takes 28 days to read her favorite novel. How many pages does the novel have?
Answers
Dawn reads 3.75 pages per day. At this rate, a favorite novel that she completes in 28 days contains 105 pages.
Explanation:This is a problem of rates and proportions.
Part A: To find out how many pages Dawn reads in a day, we divide the total pages she reads in 8 days by the number of days. Going by the data, if she reads 30 pages in 8 days, then, using the proportion, Dawn reads 30/8 = 3.75 pages per day.
Part B: To find out how many pages Dawn's favorite novel has, we multiply the rate (pages/day) by the number of days. So, if she takes 28 days to read the novel at a rate of 3.75 pages per day, then by using the multiplication principle, the novel has 3.75 pages/day * 28 days = 105 pages.
