Question:
Which interest rate is missing from Renee’s table?
Answer:
Principal- $750
Interest Rate- $00.5
Time- 11 yrs. (Years)
Interest- $412.50
Explanation:
To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate. ...
I = Interest amount paid in a specific time period (month, year etc.)
P = Principle amount (the money before interest)
t = Time period involved.
r = Interest rate in decimal.
Therefore we get an answer of $00.5

In his motorboat, Bill Ruhberg travels upstream at top speed to his favorite fishing spot, a distance of 264 mi, in 6 hr. Returning, he finds that the trip downstream, still at top speed, takes only 5.5 hr. Find the rate of Bill's boat and the speed of the current. Let x = the rate of the boat in still water and y = the rate of the current.
Answer:
The values are [tex]x = 46 miles /hr [/tex]
[tex]y = 4 \ miles / hr[/tex]
Step-by-step explanation:
From the question we are told that
The distance covered is d = 264 miles
The time taken is [tex]t_1 = 6 hours[/tex]
The time taken for the return trip is [tex]t_2 = 5.5 \ hours[/tex]
Generally during the trip toward fishing spot , the velocity is mathematically represented as
[tex]v_t = \frac{d}{t_1 } = x - y[/tex]
=> [tex]v_t = \frac{264}{6 } = x - y[/tex]
=> [tex]x - y = 44 \cdots 1 [/tex]
Generally during the return trip , the velocity is mathematically represented as
[tex]v_r = \frac{d}{t_2} = x+ y[/tex]
=> [tex]v_r = \frac{264}{5.5} = x+ y[/tex]
=> [tex]48 = x+ y\cdots 2[/tex]
add equation 1 and 2
[tex]2x = 92[/tex]
=> [tex]x = 46 miles /hr [/tex]
substituting this into equation 1
[tex] 46 - y = 44 \cdots 1 [/tex]
=> [tex]y = 4 \ miles / hr[/tex]

Mrs. Potter was going through her Halloween candy to see which kind she would bring to school. She sorted using decimal values. .17 of her 100 pieces were black licorice. .42 were m&m's. .12 were skittles. .09 were smarties. .14 were lollipops and .06 were gum drops. Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Answer:
23%
Step-by-step explanation:
She sorted using decimal values.
We convert the decimals to percent
.17 of her 100 pieces were black licorice.
.17 = 0.17 × 100 = 17%
.42 were m&m = 0.42 × 100 = 42%
.12 were skittles. = 0.12 × 100= 12%
.09 were smarties = 0.09 × 100= 9%
.14 were lollipops = 0.14 × 100 = 14 %
.06 were gum drops. = 0.06 × 100= 6 %
Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Licorice = 17%
Gum drops = 6%
The percent of her candy that she brought to school = 17% + 6%
= 23%
The percent of her candy that she brought to school is 23%

Evaluate y(-7) + 9x
When x = -6, y = 7
Answer:
-103
Step-by-step explanation:
Answer: -103
Step-by-step explanation:
y=7 so 7x(-7)= -49 because a negative times a positive always equals a negative. Same thing for 9x. x=(-6) so 9x(-6)=-54. So (-49)+(-54)= -103

The domain of this function is {-2, 3). What is the minimum value in
the range of this function?
f(x) = -2x + 5
A: {-1}
B: {9}
C: {11}
D: {-11}
Is that the right answer ?
Answer:
Yes, that is correct
Step-by-step explanation:
The formula for the slope can be referred to as "rise over run", a fraction where the rise (change in the y direction) is divided by the run (change in the x direction).
We can get the rise and run by choosing two points on the slope and looking for the change in the x and y direction. In this case, let us use the points (-4,0) and (0,-5). The change in the y direction is from 0 to -5, thus the rise will be -5. Likewise, the change change in the x direction is from -4 to 0 and the run will be 4.
Going back to "rise over run", we divide the rise by the run, giving us -5/4

176.3- 15.75
Answer:
I have that same question on my extra credit!
Step-by-step explanation:
I know the answer its 160.55 but I don't know what i should do for the problem. This is my questions:
Mina asked four friends to explain how each one solved the expression . Here are their explanations Please comment if these are the same:
Ivy’s explanation: I lined up the numbers to subtract.
176.3
- 15.75
18.8
Hannah’s explanation: I lined up the two decimals according to place value. I put a 0 in the hundredths place to make it easier for me to subtract.
176.30
- 15.75_
161.45
Jose’s explanation: I lined up the two decimals according to place value.
176.3
- 15.75
161.45
An’s explanation: I counted up from 15.75 to 176.3 to find the difference. I underlined each number I added on each line.
15.75 + 0.25 = 16
16 + 4 = 20
20 + 150 = 170
170 + 6 = 176
176 + 0.3 = 176.3
I rearranged the underlined numbers to make them easier to add: .
150 + 6 + 3 + 0.25 = 163.25

Answer:
Um... Is this the real question or you just trolling???
Step-by-step explanation:
Assuming there are no reflections or dilations, explain how you would write the equation of the function whose graph is sketched below.
Answer:
Start with the parent function y= 1/x^2
Add 3 to x in the denominator, because the graph is shifted left 3.
Add 1 to the fraction, because the graph is shifted up 1 unit.
Step-by-step explanation:
i just know
The equation of the function shown in the provided graph is [tex]y=\frac{1}{(x+3)^{2} }[/tex].
The parent function is: [tex]f(x)=\frac{1}{x^{2} }[/tex]
How horizontal shifting of the graph takes place?If a function f(x) is shifted horizontally by k units the parent function f(x) becomes f(x+k) where k>0
Since the graph is shifted towards the negative x-axis by 3 units.
So, the parent function f(x) will become f(x+3).
[tex]f(x)=\frac{1}{x^{2} }[/tex]
[tex]f(x+3)=\frac{1}{(x+3)^{2} }[/tex]
So, the equation of the function will be [tex]y=\frac{1}{(x+3)^{2} }[/tex].
Therefore, The equation of the function shown in the provided graph is [tex]y=\frac{1}{(x+3)^{2} }[/tex].
