*WILL GIVE BRAINLIEST* Simplify (5.29 x 10^9) divided by (9.32 x 10^-7). Write in Scientific Notation.
Answer: Using the corrected exponents on the reposted question:. D is the choice.
5.676×10-³
Step-by-step explanation:
5.29÷9.32=0.567596 That would be equivalent to 5.676×10-¹, like 1/0 of 5.676.
Then to calculate 10 ^-9 divided by 10^-7, we subtract the -7 from -9. -9 -(-7) = -2
That leaves us with 10-² × 10-¹ so adding the exponents we have 10-³ to multiply by 5.676 for the scientific notation.

Danielle makes $20 per week, and she already has $50. Write an equation to find y, the amount of money Danielle has after x weeks.
Answer:
50 + 20x = y
(you should get a second opinion)
Answer:
y=20x+50
Step-by-step explanation:
In slope-intercept form y=mx+b,
y is determined after the x value is plugged in
m is the slope (in this case it's 20)
x is the value you plugin
and b is the y-intercept; this value does not change
put it all together and you get y=20x+50

Four siblings have a dog walking business. The table shows the hours worked by each sibling. Each sibling earns $25.50 per hour and the total number of hours worked is represented by 10h+15 , where h represents the number of hours Michael worked.
Martin 2.5h+3
Emilio 4(h−2)
Michael h
Mario 31
Answer:
Four siblings have a dog walking business. The table shows the hours worked by each sibling. Each sibling earns $25.50 per hour and the total number of hours worked is represented by 10h+15 , where h represents the number of hours Michael worked.
Martin 2.5h+3
Emilio 4(h−2)
Michael h
Mario 31
The algebraic expression is the combination of variable and constants with some mathematical operation between them. The Earning of the four siblings are $357, $244.8, $112.2 and $790.5 respectively.
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
Given that,
The earning of the siblings per hour is $25.50.
Total number of hours worked is 10h + 15.
As per the problem the value of h can be found by equating the total number of hours to the sum of hours worked by each sibling as given in the table as follows,
2.5h + 3 + 4(h - 2) + h + 31 = 10h + 15
⇒ 2.5h + 3 + 4h - 8 + h + 31 = 10h + 15
⇒ 7.5h + 26 = 10h + 15
⇒ 2.5h = 11
⇒ h = 11 / 2.5
⇒ h = 4.4
Thus, the earning of each sibling can be calculated by substituting h = 4.4 in their working hour and multiplying it by $25.50 as follows,
Earning of Martin is given as,
(2.5 × 4.4 + 3) × $25.50 = $357
Earning of Emilio is given as,
4(4.4 − 2) × $25.50 = $244.8
Earning of Michael is given as,
4.4 × $25.5 = $112.2
Earning of Mario is given as,
31 × $25.50 = $790.5
Hence, the earnings of the four siblings are as Martin : $357, Emilio : $244.8, Michael : $112.2 and Mario : $790.5.

Jeremy bought a $60 pair of sneakers on sale for 15% off. Then, he used a coupon that gave him an additional 10% off. Can Jeremy find the cost of the sneakers by adding the percents?
by finding 25% off of $60, and
by finding 15% off of $60, and then subtracting 10% from that cost.
Complete the explanation.
25% off of $60 is equal to $
.
15% off of $60, then subtracting 10% from that cost, is equal to $

A
−4.7x+7.9
B
4.7x+7.9
C
−12.1x+7.9
D
12.1x+7.9
Step-by-step explanation:
so we know that
(8.4x+2.9)+(−3.7x+5)= 4.7x+7.9
so we need an equivelant to 4.7x+7.9
A. −4.7x+7.9= -1/10x(47x-79)
B.=4.7x+7.9=1/10x(47x+79)
C.−12.1x+7.9=-1/10x(121x-79)
D.12.1x+7.9=1/10x(121x+79)
So the answer would be B!

Anna is ordering t-shirts for a community run. The company Anna is ordering from charges $12 per shirt and a shipping fee of $8.
Based on this information, which function can be used to represent the relationship between the total cost, t, and the number of shirts Anna orders, m?
t=8m−12
t=12m−8
t = 8m + 12
t = 12m + 8
Answer:
t = 12m + 8
Step-by-step explanation:
Each shirt (m) is $12 each and each order has an additional shipping fee of $8.
Therefore, t = 12m + 8
