Step-by-step explanation:
5⁴×5² = 5⁶
10⁶/10³ = 10³
so, we have 5⁶/10³ = 15.625
and in scientific notation we have to write the first digit (which is not 0) in front of the decimal point, and the following digits of the number as pairings after the decimal point, and then indicate a multiplication with a power of 10 to tell us the right position of the decimal point in the plain number.
so, 15.625 as plain number is
1.5625 × 10¹ in scientific notation.
therefore option 1 is correct.

Step-by-step explanation:
I've attached a picture, and I hope it's clear and understandable.
Answer: k=9
Step-by-step explanation:
Parallel lines have the same slope. y=mx+b, where m is the slope. The reference line, y = 6x-5 has a slope of 6. The new line must therefore also have a slope of 6. The slope is the Rise/Run, the change in y for a change in x.
The two points on the new line are (10,2k) and (13,4k). Rise over run for this new line is (4k-2k)/(13-10) or 2k/3. This must be equal to 6,
2k/3 = 6
2k = 18
k = 9

What is the factored form of this expression?
4t2 − 27t + 18
A.
(4t − 18)(t − 1)
B.
(4t − 3)(t − 6)
C.
(2t − 9)(2t − 2)
D.
(2t − 6)(2t − 3)
Answer: B. (4t - 3)(t - 6)
Step-by-step explanation:
(4t - 3)(t - 6)
= 4t^2 - 24t - 3t + 18
= 4t^2 - 27t + 18
Answer:
B
Step-by-step explanation:
Sum = -27
Product = 18*4 = 72
Factors = (-24) ; (-3) {(-24)*(-3)=72 & (-24) + (-3) = -27}
4t² -27t + 18 = 4t² - 24t - 3t + (-3)*(-6)
= 4t(t -6) - 3(t - 6)
= (t - 6)(4t - 3)

Emma has just started a new sales job. She makes $20 an hour. On top of her hourly wages, she’ll be paid a commission of 15% on all sales she makes. Use this information to answer the following questions.
Part A
Question
Which equation in the form y = mx + cs models Emma’s situation?
y = 20x + 0.15
y = 20x + 15
y = 20x + 0.15s
y = 20x + 15s
Answer:
y = 20x + 0.15s
Step-by-step explanation:
Shew makes $20 par hour, so for x hours, she makes 20x.
She makes 15% commission on the sales, s. 15% = 0.15,so for the sales, s, she makes 15% * s = 0.15s.
The total she makes is 20x + 0.15s
Answer: y = 20x + 0.15s
The equation in the form y = mx + cs models Emma’s situation is
y = 20x + 0.15s
Shew makes $20 par hour, so for x hours, she makes 20x.
What is the slope-intercept form of the line?
The slope-intercept of the line y= mx+c
Where y co-ordinate
x- x co-ordinate
m=slope of the given line
C-y intercept.
She makes 15% commission on the sales, s. 15% = 0.15,
So for the sales, she makes
15% * s = 0.15s.
The total she makes is 20x + 0.15s
y = 20x + 0.15s

Answer:
A: (-7, -4)
B: (-3, 8)
Step-by-step explanation:
Ordered pairs are (x,y).
Count the lines and see:
A is 7 to the left and 4 down so (-7, -4)
B is 3 to the left and 8 up so (-3, 8)
REMEMBER X IS ALWAYS FIRST!!
Does this answer make sense? YES! Because quadrant II all the pairs will be (-#, #) and in quadrant III the pairs will be (-#, -#)

You are given a card number that says 9 3 4 3 9 4 8 5 3 1 7 3 2 3 6 x. If this is the credit card number what must x be?
Answer:
7
Step-by-step explanation:
it is a 16 digit credit card number. Therefore, start from the first digit and double alternating digits. Add them and the non doubled digits. should be divisible by 10. For double digits, they are added to make single digit.
9+3+8+3+9+4+7+5+6+1+5+3+4+3+3+x = 73+x
final number should be divisible by 10.

Find the value of f(5) for the function f(m) = 1 - 4(m/2) *
Answer:
f(m) = -9
Step-by-step explanation:
We replace m with 5 in the function.
f(m) = 1 - 4(m/2) becomes f(5) = 1 - 4(5/2)
then we solve the numbers in the parenthesis first
= 1 - 4 (5/2)
= 1 - 4 (2.5)
= 1 - 10
= -9
What is the slope of a line perpendicular to the line represented by the equation 2y=-6x+8
Answer:
First we need to solve the linear equation for y because we need to get the slope. Once we have the slope we need to convert it to its negative reciprocal, this means to just change the sign of the slope and flip it. The negative reciprocal is always perpendicular to the original slope.
2y = - 6x + 8
y = (-6x/2) + 8/2
y = - 3x + 4
The current slope is -3 or -3/1
The negative reciprocal is 1/3

if i fill the 42 L tank in my car and take a 360km trip. If my car consumes gasoline at a rate of 8 L per 100km how muck farther can i go before i run out of gasoline.
Using the principle of proportional relationship, the 42 L of gas can go for a further 165 km
Consumption rate = 8L for 100 km
Km per Litre :
8L = 100km
1 L = m
8m = 100
m = (100 ÷ 8)
= 12.5 kilometer per Litre
Number of kilometers for 42 L
12.5 km = 1 L
m = 42 L
Cross multiply
m = 12.5 × 42
m = 525 km
The difference in the distance = 525 - 360 = 165 km
Therefore, the gas can go for a further 165 km

Answer:
subtract 20 from both sides
Step-by-step explanation:
1. To find the answer, let's actually try solving the equation first and find the 2nd step.
2. (Solving)
Step 1: Distribute 2 to each term.
[tex](2)(x)+(2)(10)=60[/tex] [tex]2x + 20 = 60[/tex]Step 2: Subtract 20 from both sides.
[tex]2x + 20 - 20 = 60 - 20[/tex] [tex]2x = 40[/tex]3. Since we got that the second step was "subtract 20 from both sides," the answer is subtract 20 from both sides.
