Answer:
1)[tex]10+10+1+1=22[/tex]
2)[tex]10+1+1+1+1+1+1+1+1+1+1+1+1=22[/tex]
Step-by-step explanation:
Mrs. Sims has to put 22 books.
She can either put them in stacks of 10 or arrange them as single book(single stack).
There could be two ways in which she could arrange the books.
First way:
She could arrange the books in two stacks of 10 books ([tex]2\times10=20[/tex] and the remaining two books can be arranged as single books.
So, the arrangement is [tex]10+10+1+1=22[/tex]
Second way:
She could arrange books in one stack of 10 books and and remaining twelve books can be arranged as single books.
So, the arrangement is [tex]10+1+1+1+1+1+1+1+1+1+1+1+1=22[/tex]

A produce store sold 63 red apples. If the ratio of red apples to green apples sold was 7:2, what is the combined amount of red and green apples sold?
The total number of apples sold if, A produce store sold 63 red apples, The ratio of red apples to green apples sold was 7:2, which is 81.
What is the ratio?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
Given:
A produce store sold 63 red apples,
The ratio of red apples to green apples sold was 7:2,
Assume the total number of apples sold is x then,
Total number of apple sold = 7x + 2x
But the number of red apples sold is given so,
7x = 63
x = 63 / 7
x = 9
Put the value of x in the above equation,
Total number of apple sold = 7 × 9 + 2 × 9
Total number of apple sold = 63 + 18
Total number of apples sold = 81

What is the e-file rejection error for an Invalid bank account or routing transit numbers?
Answer;
The Error code "0019".
Explanation;
-The e-file rejection error for an invalid bank account or routing transit numbers is error code "0019".
-This error code may be caused by a variety of reasons and is present in tax accounting software, where an e-file sent to the IRS is rejected, hence the error name. An incomplete installation might be one of the several reasons behind an e-file rejection error.

What is 26.99 round to the nearest tenth
To round 26.99 to the nearest tenth, we increase the tenths place by 1 because the hundredths place is 9, resulting in 27.0.
When rounding 26.99 to the nearest tenth, we need to look at the hundredths place, which is 9. Since 9 is greater than 5, we round up the digit in the tenths place by 1. Therefore, the number rounded to the nearest tenth is 27.0.

HURRY!
To simplify -2i * -3i, multiply -2 by -3 to get 6, then multiply i by i to get i². Because i² is equivalent to -1 in the complex number system, multiply 6 by -1 to get your answer, which is -6.
Explanation:When multiplying two complex numbers like −2i and (−3i), the 'i' terms get multiplied together separately to the numerical terms. This is due to the distributive property of multiplication.
So, if we apply the multiplication, we would have −2 multiplied by −3 which gives us 6. Then, i multiplied by i gives us i². The term i² is defined as -1 in the realm of complex numbers.
Putting these together we get 6 x -1, that results in −6.
Therefore, the simplified value of the expression is -6, which corresponds with option c.

so 6 to 7 would be -11 -2 = -13
7 to 8 would be -13-2 = -15
8 to 9 = -15-2 = -17
B is the answer
The tax rate as a percent, r, charged on an item can be determined using the formula – 1 = r, where c is the final cost of the item and p is the price of the item before tax. Louise rewrites the equation to solve for the final cost of the item: c = p(1 + ). What is the final cost of a $40 item after an 8% tax is applied?

How long does it take $450 to double at simple interest rate of 100%
Final answer:
It will take 1 year for $450 to double at a simple interest rate of 100%, as the simple interest formula shows that the interest equals the principal when the rate is 100% and time is one year.
Explanation:
To calculate how long it takes for $450 to double at a simple interest rate of 100%, we can use the formula for simple interest: Interest = Principal × Rate × Time. Since the goal is to double the principal, the interest earned should be equal to the principal of $450.
The simple interest formula in this shape becomes:
$450 = $450 × 1 × Time
When we simplify this, we find that Time equals 1.
Therefore, it will take 1 year for $450 to double at a simple interest rate of 100%.

What is the Pythagoras theorem?The sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
a² + b² = c²
Given that a ladder leans against the side of a house. The top of the ladder is 10 ft from the ground. The bottom of the ladder is 6 ft from the side of the house.
Let the length of the ladder be x
Therefore, using Pythagoras theorem
x² = 10² + 6²
x² = 100 + 36
x = [tex]\sqrt{136[/tex]
x = 11.66 ft
Hence, the length of the ladder is 11.66 ft.

The janitor at a school discovered a leak in a pipe. The janitor found that it was leaking at a rate of 10 fl oz per hour. How fast was the pipe leaking in gallons per day?
Answer:
The pipe is leaking at the rate of 1.875 gallons of water per day.
Step-by-step explanation:
In this question we will find the leakage per day first, then convert it into gallons.
The janitor discovered a leak, leaking with a rate = 10 oz per hour
And we know that there are 24 hours in a day therefore, pipe leaking per day will be = 24×10 = 240 oz.
Since 1 oz = 0.0078125 gallons
Therefore, 240 oz = 240×0.0078125
= 1.875 gallons
The pipe is leaking at the rate of 1.875 gallons of water per day.
there are 18 Bulls and 45 Cows on a ranch if 4 more cows and 4 more Bulls are added will the ratio of the bull to cows remain the same?
The ratio of bulls to cows does not remain the same after adding 4 more cows and 4 more bulls.
Explanation:To determine if the ratio of bulls to cows remains the same after adding 4 more cows and 4 more bulls, we need to compare the new ratio to the original ratio.
Initial ratio of bulls to cows: 18/45 = 2/5
After adding 4 more cows and 4 more bulls, the new ratio becomes (18+4)/(45+4) = 22/49.
Since the new ratio is different from the original ratio, the ratio of bulls to cows does not remain the same after adding 4 more cows and 4 more bulls.

Describe and correct the error made in solving the system of equations by elimination
The error that was made is that the constant term in the second equation was not multiplied by 5.
How to solve these system of linear equations?In order to determine the solution to a system of two linear equations, we would have to evaluate and eliminate each of the variables one after the other, especially by selecting a pair of linear equations at each step and then applying the elimination method and Addition Method.
Based on the information provided, we have the following system of linear equations:
5x + 3y - z = 15 .........equation 1.
-x + 2y + 3z = 10 .........equation 2.
By multiplying the second equation by 5, we have the following:
(-x + 2y + 3z = 10) × 5 = -5x + 10y + 15z = 50 .........equation 3.
By adding equation 1 and equation 3, we have the following:
5x + 3y - z = 15
-5x + 10y + 15z = 50
13y + 14z = 65
