Answer:
Because scientific notation has to be in between 1 and 10, you would need this to be 5.2. Count the spaces and since its getting smaller your exponent is negative.
Your answer should be 5.2*10^(-3)

wyatt opend a savings account 4 years ago. the account earns 4%interest compounded quarterly if the current balance is $1,000.00 how much did he deposit initially round your answer to the nearest cent
Answer:
He deposited initially $852.82
Step-by-step explanation:
The rule of the compound interest is [tex]A=P(1+\frac{r}{n})^{nt}[/tex], where
A is the new amountP is the initial amountr is the rate in decimaln is the period of the timet is the time∵ Wyatt opened a savings account 4 years ago
∴ t = 4
∵ The account earns 4% interest compounded quarterly
∴ r = 4% = 4 ÷ 100 = 0.04
∴ n = 4 ⇒ compounded quarterly
∵ The current balance is $1,000.00
∴ A = 1,000
→ Substitute these values in the rule above to find P
∵ 1,000 = [tex]P(1+\frac{0.04}{4})^{4(4)}[/tex]
∴ 1,000 = [tex]P(1+0.01)^{16}[/tex]
∴ 1,000 = [tex]P(1.01)^{16}[/tex]
→ Divide both sides by [tex](1.01)^{16}[/tex]
∴ 852.8212622 = P
→ Round it to the nearest cent (2d.p)
∴ P = 852.82
∴ He deposited initially $852.82

Dustin's Lawn Care Service Customer Amount Paid Mrs. Schmitt $15.75 Mr. Jones $9.25 Mrs. Adams $22.50 Mr. Meyer $50.00 How much more does Dustin get paid to mow Mr. Meyer's lawn than to mow the other three lawns combined? Enter your answer in the box. I need helppppp!
Answer: $2.50
Step-by-step explanation:
The following payments are made by Dustin's Lawn Care Service Customer
Mrs. Schmitt = $15.75
Mr. Jones = $9.25
Mrs. Adams = $22.50
Mr. Meyer = $50.00
To get our answer, we need to add all the payments of the other three. This will be:
= $15.75 + $9.25 + $22.50
= $47.50
The answer will now be:
= $50.0 - $47.5
= $2.50

Answer:
y = 1
Step-by-step explanation:
Since the line never crosses the x-axis, the equation just looks like this: y = 1, because 1 is where the line crosses the y-axis.
Calculate the slope of a line that passes through the points (3, -20) and (5, 8).

Answer:
14
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(8 + 20) / (5 - 3)
28 / 2
= 14
So, the slope is 14.
What is a scale factor?
The ratio of weight of similar 2-D figures
The ratio of corresponding angles of similar figures
The ratio of corresponding sides of similar figures
The ratio of volume of similar 2-D figures
Answer:
Here is some helpful information from my mini lessons.
Step-by-step explanation:
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Here you'll learn that the ratio of the perimeters of similar figures is equal to their scale factor and that the ratio of their areas is equal to the square of their scale factor. If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor. This means that the ratio of all parts of a polygon is the same as the ratio of the sides.

The ratio of boys to girls in a class is 5:6. How many boys are there if there are 33 students in the class?
Answer:
15.
explaination:
let x be the number which we have to times to the ratio.
(5+x) + (6+x) =33
5x + 6x =33
11x = 33
x=3
so we need to times 3 the ratio to get the actual number.
boys: 5 × 3 =15
girls:6 × 3 = 18

daria bought a lemonade cup for $9 . each refill cost $2 . last month daria spent $31 on mug and refills . How many refills did she buy?
Answer:
Daria bought 11 refills of lemonade last month
Step-by-step explanation:
The equation is:
y = 2x + 9
The cup costs 9 dollars and is 2 dollars per refill
She spent 31 dollars so:
31 = 2x +9
Now we can solve!
2x + 9 = 31
Subtract 9 from both sides!
2x = 22
Divide both sides by 2!
x = 11
We know x is the amount of refills so,

15) A car salesman earns $700 per week plus 2.5% commission on his sales. If he
sold two cars for a total of $75,000 last week, how much did he make?
Please help!
Answer:
$2575
Step-by-step explanation:
For this problem, we need to form an equation that represents the car salesman's weekly income. We are given that he makes at least $700 per week and that he makes 2.5% commission for his sales. Let n represent the total amount of sales the car salesman made. So we can build the equation as follows:
f(n) = 0.025n + 700
Note that if we let n = 0 (He made no sales) then he will make his minimum weekly income of $700.
So let's use our formula to calculate how much he made for the week given he made $75000 in sales.
f(75000) = 0.025(75000) + 700
f(75000) = 1875 + 700
f(75000) = 2575
Hence, the car salesman made $2575 for the week.

The dockland building in hamburg, germany is built in the shape of a parallelogram. What is the length of the flight of stairs that runs from the ground to the rooftop? Round your answer to the nearest meter. Show your work.
Answer:
The length of the flight of stairs is 52 m
Step-by-step explanation:
In parallelograms, opposite sides are equal in length
In the given figure
∵ The building is built in the shape of a parallelogram
∵ The length of the flight of stairs is one side of it
→ We can find it by finding the hypotenuse of the right triangle
whose legs are 47 m and 22 m
∴ The length of it = the length of the hypotenuse of the right Δ
→ By using the Pythagoras Theorem
∵ h = [tex]\sqrt{(leg1)^{2}+(leg2)^{2}}[/tex]
∵ leg1 = 47 and leg2 = 22
∴ h = [tex]\sqrt{(47)^{2}+(22)^{2}}[/tex]
∴ h = [tex]\sqrt{2209+484}[/tex]
∴ h = [tex]\sqrt{2693}[/tex]
∴ h = 51.89412298
∵ h represents the length of the flight of stairs
∴ The length of the flight of stairs = 51.89412298 m
→ Round it to the nearest meter
∴ The length of the flight of stairs = 52 m
