(2 to the power of 3 x 2 to the power of -1) divided by 2 to the power of 2
Answers
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

Answers
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
Explanation
3 3/4= (4* 3)+3= 15 and you add 4 on the bottom= 15/4 then divide into 6= 6/1 so we use kcf 15/4 * 1/6= 15/24 then simplify 15/25 divide into 3/3 equal 5/8
What is -9 ÷ 2/3?
I got: -27/3
Is it right?
Answers
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.

[tex]\frac{64x^{3}-{1} }{4x-1}[/tex]
Answers
[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):

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.
Answers
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.
I hope this was semi-helpful-
I did 12,115-10,347 which equals 1,768

a. 20 − (4 ⋅ 3)
b. (20 − 4) ⋅ 3
c. 20 + 4 − 3
d. 20 ⋅ 4 − 3
Answers
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.

Harry made a scale drawing of the elementary school. The schoolyard, which is 154 meters long in real life, is 22 millimeters long in the drawing. What scale did Harry use?
1 millimeter : __ meters
I'm sorry that there is no picture or drawing
Answers
Answer:
Based on the information given, the scale
that's used by Harry for drawing the schoolyard will be 1:7000.
Firstly, it should be noted that
meter = 1000 milliliters
Therefore, 154 meters = 154,000
millimeters
Since the schoolyard is 154 meters long in real life but is 22 millimeters long in the
drawing, then the scale will be:
= 22/154000
= 1/7000
