A clipboard cost $2.23.It cost $0.58 more than a notebook.Lisa bought two clipboards and one notebook.She paid with a ten dollar bill.How much change does Lisa get?Use a tape diagram to show your thinking.
Answers
2.23 - .58 = 1.65
(2.23×2)+1.65= 6.11
Now subtract 6.11 from ten to figure out the change amount.
10 - 6.11 = 3.89
Lisa gets a change amount of [tex]\fbox {\begin\ \bf \$ 3.89\\\end{minispace}}[/tex] when she pays a ten-dollar bill for two clipboards and a notebook.
Further explanation:
It is given that the cost of a clipboard is [tex]\$\ 2.23[/tex].
Also, it is known that the clipboard costs [tex]\$\text{ }0.58[/tex] more than a notebook so the cost of one notebook is calculated as,
[tex]\fbox {\begin\\\\\begin{aligned}\text{Cost of a notebook}&= 2.23-0.58\\&=1.65\end{aligned}\end{minispace}}[/tex]
Lisa bought two clipboards and one notebook then the total cost for items bought is obtained as the sum of cost of two clipboard and cost of one notebook.
[tex]\fbox {\begin\\\\\begin{aligned}\text{Total cost of two clipboard and one notebook}&= 2.23+2.23+1.65\\&=6.11\end{aligned}\end{minispace}}[/tex]
Lisa paid a ten dollar bill for the purchase of two clipboard and one notebook, so the total change she should get back is obtained as the difference of total cost of two clipboard and one notebook from the total paid price.
The tape diagram for the price paid for two clipboards and one notebook that Lisa bought is as shown in Figure 1 (attached at the end).
Therefore, the change that Lisa gets back is calculated as,
[tex]\boxed{\begin{aligned}\text{Change that Lisa gets}&= 10-6.11\\&=3.89\end{aligned}}[/tex]
Thus, the change amount that Lisa gets after she paid ten dollar for two clipboard and one notebook is [tex]\fbox {\begin\ \bf \$ 3.89\\\end{minispace}}[/tex].

Bonita deposited $1300 into a bank account that earned 5.75% simple interest each year. She earned $299 in interest before closing the account.
If no money was deposited into or withdrawn from the account, for how many years was the money in the account?
Round your answer to the nearest whole year.
Answers
we know that
The simple interest formula is equal to
[tex]I=P(rt)[/tex]
where
I is the amount in interest
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
[tex]t=?\ years\\ P=\$1,300\\ I=\$299\\r=0.0575[/tex]
substitute in the formula above and solve for t
[tex]299=1,300(0.0575)(t)[/tex]
[tex]t=299/[1,300(0.0575)][/tex]
[tex]t=4\ years[/tex]
therefore
the answer is
[tex]4\ years[/tex]
Bonita's money was in the account for approximately 5 years.
Step 1: Define Variables and Formula
Let:
P represent the principal amount deposited (initial amount - $1300).r represent the annual interest rate (5.75% - we can convert this into a decimal by dividing by 100: 0.0575).t represent the number of years the money was in the account (unknown).I represent the total interest earned ($299).The formula for simple interest is:
I = P × r × t
Step 2: Apply the Formula to Known Values
We are given the values for I, r, and P (we can solve for P using the given information). Let's plug these values into the formula:
$299 = P × 0.0575 × t
Step 3: Solve for the Unknown (t - Number of Years)
To isolate t (the number of years), we can divide both sides by the product of P and r. However, we don't have the value of P yet.P needs to be the initial principal amount before any interest is earned. Since the question states Bonita deposited $1300, and we're calculating the interest earned, P represents the principal amount before interest.Step 4: Find the Principal Amount (P)
The total amount Bonita received when closing the account is the principal amount (P) plus the interest earned (I). We can represent this as:
P + I = $1300 (deposit amount) + $299 (interest)P = $1300 + $299P = $1599 (This is the principal amount before interest)Step 5: Solve for the Number of Years (t)
Now that we know P, we can plug it back into the equation along with the interest rate (r) to solve for t:
$299 = $1599 × 0.0575 × tt ≈ 5.49 (We haven't rounded yet)Step 6: Round the Answer (Nearest Whole Year)
The question asks for the number of years rounded to the nearest whole year. Since the decimal part (0.49) is closer to 0 than 1, we round down.

One number is 4 less than eleven times another. The sum of the two numbers is 92. Find the numbers.
Answers
8 x 11 = 88
88 - 4 = 84
84 + 8 = 92
The problem is an algebraic one involving two linear equations. By setting up correct equations, solving them step-by-step, we find that the two numbers are 8 and 84.
Explanation:This problem falls under algebra and specifically it involves solving linear equations. Let's denote the two unknown numbers as x and y. Given that 'One number is 4 less than eleven times another' we can formulate the first equation like this: y = 11x - 4. The second piece of information given is 'The sum of the two numbers is 92', so the second equation is x + y = 92.
We can substitute y from the first equation to the second equation which gives us: x + 11x - 4 = 92. Simplifying this gives us: 12x - 4 = 92. Solving for x we add 4 to both sides to get 12x = 96, and then divide both sides by 12 to find that x = 8.
Now that we have found x, we can substitute it back to one of the initial equations to find y. Substiting x = 8 into the equation y = 11x - 4 we find that y = 84. So the two numbers we are looking for are 8 and 84.

Create two whole number division problems that have a quotient of 9 and a remainder of 5. Justify which is greater using decimal division.
Answers
95/10=9.5
Answer and explanation;
If we choose two whole numbers; 8 and 10
We want to divide certain numbers by 8 and 10 to get 9 remainder 5.
In this case; 77 divided by 8 is equal to 9 rem 5
and 95 divided by 10 is equal to 9 rem 5
To justify which is greater, we use decimal division;
= 77 divided by 8 we get 9.625 ( 77 ÷ 8 = 9.625)
and
= 95 divided by 10 is equal to 9.5 (95 ÷10 = 9.5)
Therefore; the first case is greater since 9.625 is greater than 9.5
That is; 9 rem 5 got after dividing 77 by 8 is greater than 9 rem 5 got after dividing 95 by 10.

Alicia's mp3 player contains 1260 songs. Given that 35% of the songs are rock songs and 20% are rap songs, how many of the songs are other type of songs?
Answers
Answer:
There are 567 of the songs are other.
Step-by-step explanation:
Since 55% of the songs are rock and rap, 45% of the songs are other.
To find 45% of 1260 we multiply by the decimal:
1260 x 0.45 = 567
The answer is 567
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Rock and rap songs make 55% of the songs then the rest of the songs should make 45% of the total songs.
Thus we have 45% of 1260=567
Hence, The answer is 567

six pipes are laid to the end to form a row each pipe is 9 1/3 inches how loong is the row of pipes
Answers
To calculate the total length of six pipes each of 9 1/3 inches long, multiply the length of one pipe by the number of pipes. By doing so, we find that the row of pipes would be approximately 56 inches long.
Explanation:The question asks how long a row of six pipes would be if each pipe was 9 1/3 inches long. To figure this out, you multiply the length of one pipe by the number of pipes. In this case, that would be 9 1/3 inches times six pipes.
To simplify the calculation, convert the fraction 1/3 to a decimal. 1/3 is approximately 0.333, and adding that to 9 makes 9.333 inches. Now that we have a decimal, we can multiply: 9.333 inches per pipe times 6 pipes equals approximately 56 inches.
Therefore, a row of six pipes each of 9 1/3 inches long would be approximately 56 inches long.

Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
108° → 12 people.
Per degree people or the ratio of degree to people will be,
1° → 12/108 people
In a circle, there is 360° thus multiply by 360 on both sides,
360° = 12/108 x 360 = 40 people
