Answer:
6.34 × 10²
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 634
New Number: 6.34
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 6 . 3 4
Decimal Count: 1 2
There are 2 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 6.34
b = 2
Now the whole thing:
6.34 x 10²
Step 4
Check your work:
10² = 100 x 6.34 = 634
Answer:
6.34 x 10^2
Step-by-step explanation:
Move the decimal place to the left 2 positions
The government has decided to give a $1,000 tax rebate to each household in order to stimulate the economy. The government statistics say that each household will spend 90% of the rebate in goods and services. The businesses and individuals who benefited from that 90% will then spend 90% of what they received and so on.
What is the total effect of the rebate on the economy?
What will the total effect be if the rebate is $5000 to each household in order to stimulate the economy if each household will spend 90% of the rebate in goods and services?
Answer:
1.) The total effect of 90% of the $1,000 tax rebate would be 10,000 growth in the economy. Second question, the total effect of 90% of $5,000 would be 50,000 in growth in the economy. *Same concept different amount.
Step-by-step explanation:
1. S=[tex]\frac{a_1{} }{1-R}[/tex] 2. S=[tex]\frac{a_{1} }{1-R}[/tex]
S=[tex]\frac{1000}{1-0.9}[/tex] S=[tex]\frac{5,000}{1-0.9}[/tex]
S= 10,000 S=50,000

What is the value of 4x-7 when X-4?
O 1
O 9
O 16
O 23
Answer:
Was the question meant to say "what is the value of 4x-7 when x=4?" if so the answer is 9.
Step-by-step explanation:
First plug in 4 for x. The equation should then read 4(4) -7
Next use pemdas to solve (multiple 4 × 4 and then subtract 7 to get the answer 9
6. If n (E) = 40, n (A) = 22, n (ANB) = 8 and n ((AUB)') = 6, determine n(B)
Answer:
4
Step-by-step explanation:
First n(AUB)=n(E) - n((AUB)')
So n(AUB) = 40 - 6 = 34
Now all u hv to do is use the formulae,
n(AUB) = n(A) + n(B) - n(ANB)
So when u substitute above values,
34=22 + n(B) - 8
So,
n(B) = 4
the endpoints of a line segment are G(1,7) and H(-3,11). Find the coordinates of the midpoint M.
Answer:
The answer is
( 1 , 9)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
G(1,7) and H(-3,11)
The midpoint is
[tex]M = ( \frac{ - 1 + 3}{2} , \: \frac{7 + 11}{2} ) \\ = ( \frac{2}{2} \: , \: \frac{18}{2} )[/tex]
We have the final answer as
( 1 , 9)Hope this helps you

3x-2(x+3)=4x-9-x is the question
Answer:
[tex]\large\boxed{x = 7}[/tex]
Step-by-step explanation:
3x - 2(x + 3) = 4x - 9 - x
Start by multiplying 2 by the values in the parenthesis
3x - 2x + 6 = 4x - 9 - x
Subtract 3x - 2x and 4x - x
x + 5 = 3x - 9
Add 9 to both sides of the equation
x + 14 = 3x
Subtract x from both sides of the equation
14 = 2x
Divide both sides of the equation by 2
[tex]\large\boxed{x = 7}[/tex]

Among the 112 participants of a roller skate race, 48 are boys and 64 are girls.
What is the ratio of boys to girls?
Answer:
The ratio of boys to girls is 3:4Step-by-step explanation:
This excercise, focuses on ratio problem, and it has to do with the representation of ratio, since we can represent ratio in different ways. let us represent this ratio in the normal/ usual format.
we will first reduce the given value and represent it in the ratio format
given that for roller skate race, 48 are boys and,
roller skate race, 64 are girls
we have the ratio as
=48/64 divide both denominator and numerator by 4
=12/16 further divide both denominator and numerator by 4
=3/4
The ratio is 3:4
