Consider the rational number 3/11 (A What are the values of a and b in a)‾b when you use divisison to find the decimal form?
Answer:
The decimal form of this rational number is .
Step-by-step explanation:
a) Let a rational number. From statement we understand that represents the numerator, while corresponds with the denominator of the rational number. Hence, is 3 and is 11.
b) The decimal form is obtained by dividing by , we presented the step needed to determine the decimal form:
i) Multiply the numerator by 10:
Dividend: 30/Divisor: 11/Known result: 0. /Residue: N/A
ii) Multiply the divisor by 2 and subtract from the dividend:
Known result: 0.2 /Residue: 8
iii) Multiply the residue by 10:
Known result: 0.2 /Residue: 80
iv) Multiply the divisor by 7 and subtract from the residue:
Known result: 0.27 /Residue: 3
v) Multiply the residue by 10:
Known result: 0.27 /Residue: 30
vi) Multiply the divisor by 2 and subtract from the residue:
Known result: 0.272/Residue: 8
vii) Multiply the residue by 10:
Known result: 0.272 /Residue: 80
viii) Multiply the divisor by 7 and subtract from the residue:

I believe if you have 48 red flowers you divide 48 by 4 which gives you 12.12*5 is 60 correct me if I'm wrong.
(2 to the power of 3 x 2 to the power of -1) divided by 2 to the power of 2
Answer:
1
Step-by-step explanation:
(2^3 x 2^-1) / 2^2
First, solve what's in the parentheses remembering that when two exponents have the same base and are being multiplied together, their exponents add together:
3 + (-1) = 2
(2^2) / 2^2
And when two exponents with the same base are being divided by each other, the exponents subtract:
2 - 2 = 0
(2^0)
And any number to the power of 0 equals 1:
(2^0) = 1

One way to solve this question is through a determinant.
| X Y 1 |
| X₁ Y₁ 1 | = 0
| X₂ Y₂ 1 |
as
(X₁; Y₁) = (0; 3)
(X₂; Y₂) = (4; 2)
then
| X Y 1 |
| 0 3 1 | = 0
| 4 2 1 |

Evaluate: 42 − 12 ÷ 6
—————————————————
(6 − 3) × 4 − 7
Answer:
42 - 12 ÷ 6 = 40
(6 - 3) x 4 - 7 = 5
Step-by-step explanation:
First of all, when coming over to an equation with a division or multiplication sign, we first solve the division or multiplication first, then the subtraction or addition. So, 12 ÷ 6 = 2. Then, 42 - 2 = 40. And in the other one we must first solve what's in the parenthesis. So, 6 - 3 = 3. Then, we multiply, 3 x 4 = 12. Then subtract. 12 - 7 = 5.
Hope this helps :)

Which expression has the same value as 36 ÷ 6 ⋅ 2
a. (36 ÷ 6) ⋅ 2
b. 36 ⋅ 6 ÷ 2
c. 36 ÷ (6 ⋅ 2)
d. 36 ÷ 2 ⋅ 6
3 = x/36
Solve x. Show working
Answer:
[tex] \sf \: x=108[/tex]
Step-by-step explanation:
3=x/36
Step 1: Multiply both sides by 36.
3=x/36(3)*(36)=(x/36)*(36)
108=x
Step 2: Flip the equation.
x=108
Which expression has the same value as 20 − 4 ⋅ 3
a. 20 − (4 ⋅ 3)
b. (20 − 4) ⋅ 3
c. 20 + 4 − 3
d. 20 ⋅ 4 − 3
Answer:
a. 20 - (4 ⋅ 3)
Step-by-step explanation:
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Please note that multiplication 4 ⋅ 3 will happen before the subtraction -
If we add parentheses, we introduce a new "order". But if the parentheses are around the first operation we perform, the order stays the same!
This means that answer a. must be correct.
We verify:
20 − 4 ⋅ 3 = 20 - 12 = 8
a. 20 − (4 ⋅ 3) = 20 - 12 = 8
b. (20 − 4) ⋅ 3 = 16 ⋅ 3 = 48
c. 20 + 4 − 3 = 21
d. 20 ⋅ 4 − 3 = 80 - 3 = 77
Answer: A: 20 - (4 x 3)
Step-by-step explanation:
In the end, the final answer is 8, so we need to see which one of these options give us 8. As seen, we first must solve the multiplication, and the first option, A, solves the multiplication first because it is in parenthesis, which gives us 8, so the correct answer is A.
Solve for z.
−1.2z−8.2>−9.7
Show the solution
Hello!
Inequality: [tex]-1.2z-8.2 > -9.7[/tex]
To solve, we need to add 8.2 to both sides of the inequality:
[tex]-1.2z-8.2+8.2 > -9.7+8.2\\-1.2z > -1.5[/tex]
Now to get our solution, we will need to divide both sides by -1.2:
[tex]\frac{-1.2z}{-1.2} > \frac{-1.5}{-1.2}\\[/tex]
Final answer:

c. 7 − (6 ⋅ 3) + 2
d. (7 − 6) ⋅ (3 + 2)
Answer:
7 − (6 ⋅ 3) + 2
Step-by-step explanation:
7 − 6 ⋅ 3 + 2
PEMDAS says we need to multiply before we add and subtract

[tex]\frac{64x^{3}-{1} }{4x-1}[/tex]
[tex] \bf{= \frac{64 {x}^{3} - 1 }{4x - 1} }\\ \\ \bf{= \frac{( \cancel{4x - 1})(16 {x}^{2} + 4x + 1) }{ \cancel{4x - 1}}} \\\\ \bf{= 16 {x}^{2} + 4x + 1}[/tex]
Answer:
[tex]16x^2+4x+1[/tex]
Step-by-step explanation:
Given expression:
[tex]\dfrac{64x^3-1}{4x-1}[/tex]
Step 1Factor the numerator of the given expression.
Rewrite 64 as 4³ and 1 as 1³:
[tex]\implies (4^3)x^3-1^3[/tex]
[tex]\textsf{Apply the exponent rule} \quad a^b \cdot c^b=(ac)^b:[/tex]
[tex]\implies (4x)^3-1^3[/tex]
[tex]\textsf{Apply the Difference of Cubes Formula} \quad x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right):[/tex]
[tex]\implies (4x)^3-1^3=(4x-1)\left((4x)^2+4x(1)+(1)^2\right)[/tex]
[tex]\implies (4x)^3-1^3=(4x-1)\left(16x^2+4x+1\right)[/tex]
Step 2Replace the numerator in the given expression with the factored numerator from step 1:
[tex]\implies \dfrac{64x^3-1}{4x-1}=\dfrac{(4x-1)\left(16x^2+4x+1\right)}{4x-1}[/tex]
Cancel the common factor (4x - 1):
[tex]\implies 16x^2+4x+1[/tex]
Theresa's Book Barn sold $10,347 worth of books during September. In October, their sales were $12,115. How much higher were Theresa's book sales during October than in September? Explain how you got your answer.
Answer:
$1,768
Step-by-step explanation:
We know that Theresa's Book Barn sold $10347 worth of books in September, and $12,115 in October. Since we want to know how much higher the sales were in October than in September, we would have to subtract.
So, we would have to subtract the two numbers.
12,115
- 10,347
1768
Subtracting the two numbers gives us $1,768, which is the difference.

What is -9 ÷ 2/3?
I got: -27/3
Is it right?
Answer:
1.35
Step-by-step explanation:
Unfortunately you are wrong, the correct way to evaluate this problem…
We know 2/3 is 6.6 repeating
So if we do 9 divided by 6.6
We would get 1.35
Also I don’t know how your teacher want you to evaluate, but -27/3 can become a mixed number (9) which is obviously incorrect because 9 divided by a decimal lower that 1 is going to be a decimal lower than one.
A lizard can lose its tail to escape a predator, and the tail will grow back at a constant rate. After 6 weeks, a lizard's tail has regrown to 3 3/4 inches long. Find the number of inches the tail grew each week.
Answer:
15/24 or 5/8 inches each week
Explanation and Checking part below :)
Step-by-step explanation:
3 3/4 ÷ 6
1. Turn the mixed number into an improper fraction.
15/4 ÷ 6/1
2. Use the KCF (keep,change,flip) method (multiply the reciprocal).
15/4 × 1/6 = 15/24
3. Simplify if needed to.
15/24 ----> simplified is 5/8
Check:
5/8 × 6 = 30/8
30/8 = 3 6/8 -----> Simplified to 3 3/4
