Answer:
2^27
Step-by-step explanation:
Given the following expression:
[(2^10)^3 x (2^-10)] ÷ 2^-7
This can be easily simplified. Let us simplify the numerator first. To do that, we have
(2^10)^3 making use of the power rule of indices that says:
(A^a)^b = A^ab where a and b are powers, we have:
2^(10x3) = 2^30
Therefore the numerator becomes:
2^30 x 2^-10. Also making use of the multiplication rule that says:
A^a x A^b = A^(a + b), we have
2^30 x 2^-10 = 2^(30 – 10) = 2^20.
Now we have:
(2^20) ÷ (2^-7)
To simplify this, we need the division rule of indices which says:
A^a ÷ A^b = A^(a – b)
Therefore we have:
(2^20) ÷ (2^-7) = 2^[20 – (–7)] = 2^(20+7) = 2^27
Following are the solution to the given expression:
Given:
[tex]\to \frac{[(2^{10})^3 \times (2^{-10})]}{2^{-7}}[/tex]
To find:
value=?
Solution:
[tex]\to \frac{[(2^{10})^3 \times (2^{-10})]}{2^{-7}}[/tex]
Using formula:
[tex]\to (A^a)^b = A^{ab}\\\\\to A^a \div A^b = A^{(a - b)}[/tex]
Solve the equation:
[tex]\to \frac{[(2^{30}) \times (2^{-10})]}{2^{-7}} \\\\\to \frac{(2^{30})}{2^{-7}} \times \frac{(2^{-10})}{2^{-7}} \\\\ \to \frac{(2^{30})}{2^{-7}} \times \frac{(2^{-10})}{2^{-7}} \\\\\to (2^{30 - (-7)}) \times (2^{-10- (-7)}) \\\\\to 2^{37} \times 2^{-3} \\\\\to 2^{37 -3} \\\\\to 2^{34} \\\\[/tex]
Therefore, the final answer is "[tex]\bold{2^{34}}[/tex]".

What is the answer ???????????????
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x - 9 → (1)
y = x - 3 → (2)
Substitute y = 4x - 9 into (2)
4x - 9 = x - 3 ( subtract x from both sides )
3x - 9 = - 3 ( add 9 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations for y
Substituting into (2)
y = 2 - 3 = - 1
solution is (2, - 1 )
Simon has a farm and has to buy a certain amount of feed for each animal. He buys feed once a month and counts all of his animals to see how much feed he needs to buy. Chicken feed is about $0.5 per chicken, each horse eats about $5 worth of feed, and goats eat about $4 worth of feed. What equation should he use to find how much he should spend on feed?
A. 0.50 +5h + 4g = total spent on feed
B. 9.5a = total spent on feed
C. 0.50 +5h + 40 = 100

D
30 cm
The length of the rectangle is increased by 10%.
The width of the rectangle is increased by 5%.
Find the percentage increase in the perimeter of the rectangle.
answer
15.5%
Step-by-step explanation:
length = 30
30+10%=33
breadth=20
20+5%=21
area of rectangle = length × breadth
600² centimeters = 30 × 20
693² centimeters = 33 × 21
Increase = 15.5%
a motor bike travels 240 km in 4 hours. How long will it take to travel 450 km
Answer:
7 hours and 30 minutes
Step-by-step explanation:
[tex]240 \div 4 = 60km \: per \: h[/tex]
[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]
It will take motor bike 7.5 hours to cover 450 Km of distance.
What is Speed in Kinematics?Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.
Mathematically-
S = Δd/Δt or S = {d(2) - d(1)}/{t(2) - t(1)}
It is a scalar quantity as it only has magnitude and no direction.
Given is a motor bike travels 240 km ins 4 hours.
We can calculate the speed of the bike as -
s = 240/4 = 60 Km/hr
Then, the time taken to cover 450 Km will be -
t = 450/60
t = 7.5 hours
Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

Write an equation in slope intercept form of the line that passes through (-2,10) and (1,1).
Answer:
(-2,10)=x1,y1
(1,1)=x2,y2
we have,
(y-y1)=(y2-y1)/(x2,x1)[(x-x1)]
(y-10)=(1-10)/(1+2)[x+2]
y-10=-9/3(x+2)
y-10=-3(x+2)
y-10=3x+6
y=3x+16
Answer:
y = -3x + 4Step-by-step explanation:
The slope of a line passing through two points: (x₂, y₂) and (x₁, y₁) is:
[tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(-2, 10) ⇒ x₁ = -2, y₁ = 10
(1, 1) ⇒ x₂ = 1, y₂ = 1
So:
[tex]\bold{m=\dfrac{1-10}{1+2}=\dfrac{-9}{3}=-3}[/tex]
The point-slope form of equation of line is y - y₀ = m(x - x₀)
We can pick any of given poins, so:
x₀ = 1, y₀ = 1 and m = -3
y - 1 = -3(x - 1)
y = -3x + 3 + 1
y = -3x + 4 ← slope intercept form of the line
Below is a table of values representing a function/linear equation. What is the slope? Explain how you got it.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Is the function representing the weekly paycheck amount of Salesman A a proportional relationship? Use complete sentences to explain your reasoning.

I need help on how to solve 8 × 6 + (12 - 4) ÷ 2
Answer:
42Step-by-step explanation:
8x6+(8)/2
48+4
42
Answer:
52
Step-by-step explanation:
So in order to answer this question we are going to have to use the order of operations by starting with the parenthesis of subtracting 4 from 12:
8 × 6 + (12 - 4) ÷ 2
12 - 4 = 8
Now the equation looks like this:
8 × 6 + 8 ÷ 2
Now we multiply 8 by 6 and dividing 8 by 2 because multiplication and division come first:
8 * 6 = 48
8/2 = 4
So the equation looks like this:
48 + 4
We now add them together to get our answer:
48 + 4 = 52
So the answer to this equation is 8 × 6 + (12 - 4) ÷ 2 = 52
