Answer:
20
Step-by-step explanation:
This equation is in slope-intercept form which is y=mx+b where m is the slope and b is the y-intercept. Therefore, the slope is 20
For every quarter spent, Reggie receives 50 food pebbles to feed the fish at a hatchery. Reggie has thrown 350 food pebbles into the fish pools. Find the number of quarters Reggie spent at the hatchery. (Please use a label with this solution) *
Answer:
Reggie has spent
Step-by-step explanation:
7 quarters
Answer:
7 quarters
Step-by-step explanation:
We know that for every quarter, Reggie would receive 50 food pebbles, we also know that he has thrown 350 food pebbles into fish pools. So let's create an equation, q is for the quarters.
50(q) = 350
Since every quarter gives Reggie 50 food pebbles, then the q variable will go next to 50, and since we need to reach the total amount of 350, we put it on the opposite side.
Solve for q by isolating it, divide 50 from both sides:
[tex]\frac{50q}{50} =\frac{350}{50}[/tex]
[tex]q = 7[/tex]
Therefore, Reggie used 7 quarters for 350 food pebbles.

Grace found a red dress that cost $90, but saves $27 by using a coupon. For what percentage off is this coupon?
Becky received a statement on her Certificate of Deposit showing that her investment had returned $6,336 over its life. If the Certificate of Deposit pays a simple interest rate of 4.4% and her initial investment was $16,000, how long had the money been invested?
The amount of money returned as interest depends on the initial
amount, the interest rate and the number of years.
Response:
The money has been invested for 9 yearsWhat is simple interest and how can the duration of investment be found?Given:
The return on investment = $6,336
Amount the Certificate of Deposit pays = 4.4% simple interest
The initial investment (the principal), P= $16,000
Required:
The duration the initial amount of money had been invested.
Solution:
Interest = Principal × Rate × Time
Which gives;
[tex]Time = \mathbf{ \dfrac{Interest }{ Principal \times Rate}}[/tex]
Therefore;
[tex]Length \ of \ time \ of \ the \ investment = \mathbf{ \dfrac{\$6,336}{\$16,000 \times 0.044(/year)}} = 9[/tex]
The duration the money had been invested = 9 yearsLearn more about simple interest here:

Answer:
If I am correct both figures are similar because of AA (angle reasoning). They have the same angles meaning they are similar triangles even if they don't fit the SSS, SAS, etc. reasoning
Step-by-step explanation:
You could also do the cross multiply divide method to determine if they equal the corresponding length (which they do!) hope this helps! :)
edit: Question 4) is similar following the AA statement for triangles
Question 5 is not similar because it doesn;t match doing the cross multiply divide and has two right angles because they are
rectangles!
Question 1) Corresponding angles are related in two similar figures because they are the same. In triangles two figures similarity can be determined by identifying if they share two angles.
Question 2) Corresponding side lengths can determine the similarity by proving that the shape was only transformed by a scale factor and did not alter shape.
Question 3) No, not neccesarily. If they are the same size, length, and shape they are congruent. Similar figures are altered and different based on a scale factor

2. Ah Seng was asked to deliver 64 bowls of bean curd. For each bowl of bean curd he delivered, he was paid $0.20. However, he would have to pay 5¢ for every bowl of bean curd he spilled. At the end of the day, he earned $11.80. How many bowls of bean curd did Ah Seng spill?
Step-by-step explanation:
0.20×64=12.80
12.80-11.80= 1 dollar of bowls spilled so 100÷5=20
20 bowls are spilled
Function? Explain why or why not.
Answer/Step-by-step explanation:
If the vertical line touches the graph at more than one point, then the graph is not a function.Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function.
[RevyBreeze]
Yes it's a function
As per the defination of function.
If every domain of the relationship has an unique range that's a function
f(x)=ySo
Here
f(0)=0And rest also have unique range
So it's a function
6. The value of a car depreciates by 22.5% per year. After how many years is
the value of the car first less than 40% of its original value
[tex]\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\dotfill &\stackrel{40\%~of~P}{0.4P~~~~}\\ P=\textit{initial amount}\dotfill &P\\ r=rate\to 22.5\%\to \frac{22.5}{100}\dotfill &0.225\\ t=\textit{elapsed time}\\ \end{cases} \\\\\\ 0.4P=P(1-0.225)^t\implies \cfrac{0.4P}{P}=(1-0.225)^t\implies 0.4=0.775^t[/tex]
[tex]\log(0.4)=\log(0.775^t)\implies \log(0.4)=t\log(0.775) \\\\\\ \cfrac{\log(0.4)}{\log(0.775)}=t\implies \stackrel{\textit{about 3years, 215days and 8hrs}}{3.59\approx t}[/tex]
so at that time the value is 40% of its original value, I guess is less than that a minute or an hour later.
Seven boys hire DVD's and each pays R5,50. If 4 friends join in, how much will they each pay then?
Seven boys hire DVD's and each pays R5,50
I assume R 5.50 ( R to be the currency)
also assuming that they dont hire any more DVDs
total amount paid by 7 boys
= 5.50 × 7
= 38.5
when 4 more friends join the amount should get divided by 11 ( 7 + 4 )
so each has to pay an amount of 38.5 / 11 = 3.5
I think my assumptions here were correct
if not

Glenda and Fiero are at a restaurant eating meal that costs $30. They have a discount coupon that gets them 10% off the cost. If they pay the waiter a tip of 8% of their bill, how much are they spending on dinner including tip? (I ALREADY KNOW THE ANSWER. BUT I NEED THE WORK FOR THE ANSWER TO SHOW MY TEACHER) (the answer is $29.16))
The cost of meal = [tex]$30[/tex]
The tip to the waiter = [tex]8%[/tex]%
Discount = [tex]10%[/tex]%
Cost = [tex]30 + 0.08 * 30 - 0.1 * 30[/tex]
Cost = [tex]30(1 + 0.08 - 0.1)[/tex]

PLEASE HELP ASAP PLEASE!!!!
Answer:
(3,2)
Step-by-step explanation:
2x-4=y
2y+3x=13
We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation
2(2x-4) +3x=13 : *distribute*
4x-8+3x=13 : *combine like terms*
7x-8=13 * add the 8 to the other side*
7x=21 *divide*
x=3
So the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3 we plug it into the other equation preferably.
2(3)-4 =y : 6-4=y : 2=y
We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.
2x-4=y 2(3)-4=(2) 2=2
2y+3x=13 2(2)+3(3)=13 13=13
Solve the inequality. Graph and check your solutions.

Answer:

Recursive Sequence Function
A recursive sequence is a sequence of numbers whose values are determined by the numbers that come before them in the sequence.
We’re given a sequence whose (n + 1)-th term f(n + 1) depends on the value of the n-th term f(n), specified by the recursive rule
f(n + 1) = -4 f(n) + 3
We’re also given the 1st term in the sequence, f(1) = 1. Using this value and the recursive rule, we can find the next term f(2). (Just replace n with 1.)
f(1 + 1) = -4 f(1) + 3
f(2) = -4 • 1 + 3
f(2) = -1
We do the same thing to find the next term f(3) :
f(2 + 1) = -4 f(2) + 3
f(3) = -4 • (-1) + 3
f(3) = 7
One more time to find the next term f(4) :
f(3 + 1) = -4 f(3) + 3
f(4) = -4 • 7 + 3
f(4) = -25
