Marcia bought a 500 g packet of flour. She used some flour to bake a cake, and she used two thirds of the remaining flour to make some scones. She used 60 g more flour for the cake than for the scones. How much flour did Marcia use for the cake?
Answer:
The answer should be 236g.
Step-by-step explanation:
If we take the amount of flour used for the cake as 'x,' the flour used to make the scones would be (500-x)×2/3 as 2/3 of the remaining is used for the scones.
We know that 60g more flour is used for the cake.
So,
x-60=(500-x)×2/3
Cross multiply, and brng the 3 to the other side.
3(x-60)=(500-x)2
3x-180=1000-2x
Bring the x-terms to one side and the numbers to one side.
3x+2x=1000+180
5x=1180
Divide both sides by 5 to find x(the amount of flour used to make the cake)
Therefore,
x=236g

What are the first five terms of the recursive sequence?
9, 30, 93, 282, 849
====================================================
Explanation:
The first term is 9 because of the notation [tex]a_1 = 9[/tex]
To get the second term, we use the recursive rule given to us which is
[tex]a_n = 3a_{n-1} + 3[/tex]
I recommend using parenthesis to separate things like this
[tex]a_n = 3(a_{n-1}) + 3[/tex]
If n = 2, then,
[tex]a_n = 3(a_{n-1}) + 3\\\\a_2 = 3(a_{2-1}) + 3\\\\a_2 = 3(a_{1}) + 3\\\\a_2 = 3(9) + 3\\\\a_2 = 27 + 3\\\\a_2 = 30[/tex]
The second term is 30.
You can use the same idea as above to find the third term, or you can use this slightly different approach
[tex]\text{third term} = 3*(\text{second term}) + 3\\\\\text{third term} = 3*(30) + 3\\\\\text{third term} = 90 + 3\\\\\text{third term} = 93[/tex]
To generate any new term, we first triple the previous term and then add on 3.

A farmer needs to water a new potato field. To do so, he builds an irrigation system using 610
plastic pipes and 82 metal pipes. How many pipes does he use?
Answer: Irrigation water can come from groundwater, through springs or wells, surface water, through rivers, lakes, or reservoirs, or even other sources, such as treated wastewater or desalinated water. As a result, it is critical that farmers protect their agricultural water source to minimize the potential for contamination.
Step-by-step explanation:
Answer:
Total pipes = 692 pipes
Step-by-step explanation:
Now we have to,
→ find the amount of pipes he use.
Forming the expression,
→ 610 plastic pipes + 82 metal pipes
Let's solve the problem,
→ 610 plastic pipes + 82 metal pipes
→ 610 + 82
→ 692 pipes
Hence, the farmer used 692 pipes.

a jeweler sells rings for $35 each plus a flat fee of $5 for shipping for orders up to 10 rings. If customers order more than 10 rings, the cost is $30 per ring and shipping is free. Write a piecewise function to represent the situation.
Answer:
-10=$35r+$5r
+10=$30r
Step-by-step explanation:
This function represents this situation. If someone orders less than ten rings (-10) then they will pay $35 for each ring($35r) plus dollars for each for shipping ($5r)
If someone were to buy more than ten rings (+10) then they will pay $30 for each ring ($30r)

Consider the equation y = 3x - 1
Identify the slope and y-intercept and
sketch the graph.
Given :-
A equation y = 3x -1 .To Do :-
To identify slope and y intercept and then sketch it's graph .Solution :-
Given equation to us is ,
→ y = 3x -1
As we know that , the slope intercept form of the line is ,
→ y = mx + c
where m is the slope and c is the y intercept .On comparing both , we have ,
slope = 3 y intercept = -1 .So the graph will cut the y axis at (0,-1) . And will have a slope of 3 .
When y coordinate is 0 ,
say the point is (x,0) .So that ,
→ x - 0 / 0 -(-1) = 3
→ x/0+1 = 3
→ x/1 = 3
→ x = 3
Hence one other point is (3,0 ).
Now we may plot the graph using these two points (3,0) and (0,-1) .
For graph see attachment .

The bull’s-eye on a target has a diameter of 5 inches. The whole target has a diameter of 13.5 inches. What part of the whole target is the bull’s-eye? Enter your answer as a decimal.
Answer:
13.71% or rounded we have 14%
Step-by-step explanation:
We need to find the area so we need to use the formula of Area = piR^2
>> Area of bulls-eye = π(2.5)^2 = 19.63in^2
>> Area of whole target = π(6.75)^2 = 143.13in^2
NOTE: The target values above are halved values of 5 and 13.5
Now, all we have to do is divide the area of the bullseye by the area of the target, so some simple stuff.
19.63/143.13 > 0.13714804 > In a percent we have 13.71% or rounded we have 14%

George decided to accept a 20% drop in his salary during 2020.By what percentage must George's salary increase to get back to where it was before the salary drop during 2020
Answer:
25%
Step-by-step explanation:
Let George's salary = $50,000 per year
If his salary dropped by 20%, then his salary would be 80% of his previous salary (as 100% - 20% = 80%).
Convert 80% to a decimal: 80% = 80/100 = 0.8
Therefore, 80% of 50000 = 0.8 x 50000 = $40,000
We wish to increase his salary back to the original amount of $50,000.
The difference between the two salaries is : 50000 - 40000 = 10000
Therefore, we need to calculate the percentage that $10,000 is of $40,000.
⇒ (10000 / 40000) x 100 = 25%
So George's salary needs to increase by 25% to get back to where it was before the salary drop.

6) Write the equation, g(x), that is 9 units below f(x) = 3^X+ 2.
Answer:
g(x) = 3^x -7
Step-by-step explanation:
In an exponential function like this, the constant at the end of the function represents the vertical shift. This means that the original function is shifted 2 units up. So, 9 units lower than +2 is -7. Thus, the new function, g(x), is g(x)=3^x - 7.
We can prove that g(x) is 9 units lower through y-intercepts. The function f(x) has a y-intercept of 3 and g(x) is -6. Since -6 is 9 lower than 3, we know that there is a 9 unit difference between the functions.

Are the expressions 4a+(5a+3c) and (4a+5a)+3c equivalent? If so, determine what property can be applied to determine that they are equivalent.
Answer:
Yes, they are equivalent expressions, by the Associative Property
Step-by-step explanation:
Both of these expressions are equal to:
4a + 5a + 3c
(and then, 9a + 3c)
This is all adding so you can add them all up without any of the parentheses. In the question at first the parentheses are grouping together the 5a and 3c, but in the second expression they are wrapped around the 4a and 5a. But in both expressions the order of the three terms does not change. Only the grouping changes. The terms are grouped differently, but the order DOES NOT change. This is Associative property. If the order changes it is Commutative property.

How many 6-digit whole numbers have the digits 2, 0, 2, and 2 as a 4-digit consecutively ordered block with no other digits between them?
There are 1680 digits 2, 0, 2, and 2 as a 4-digit consecutively ordered block with no other digits between them
How to determine the selectionTo determine the number of whole numbers, the following must be true
Case 1: If the sequence starts from the first digit
The first digit can be any of the three 2's (i.e. 3 digits)The second digit can only be 0The third digit can be any of the remaining 2's (i.e. 2 digits)The fourth digit can only be the last 2 (i.e. 1 digit)The fifth digit can be any of 0 - 9 (i.e. 10 digits)The sixth digit can be any of 0 - 9 (i.e. 10 digits)So, we have:
[tex]Case\ 1 = 3 * 1 * 2 * 1 * 10 * 10[/tex]
[tex]Case\ 1 = 600[/tex]
Case 2: If the sequence starts from the second digit
The first digit can be any of 1 - 9 (i.e. 9 digits)The second digit can be any of the three 2's (i.e. 3 digits)The third digit can only be 0The fourth digit can be any of the remaining 2's (i.e. 2 digits)The fifth digit can only be the last 2 (i.e. 1 digit)The last digit can be any of 0 - 9 (i.e. 10 digits)So, we have:
[tex]Case\ 2 = 9 * 3 * 1 * 2 * 1 * 10[/tex]
[tex]Case\ 2 = 540[/tex]
Case 2: If the sequence starts from the third digit
The first digit can be any of 1 - 9 (i.e. 9 digits)The second digit can be any of 0 - 9 (i.e. 10 digits)The third digit can be any of the three 2's (i.e. 3 digits)The fourth digit can only be 0The fifth digit can be any of the remaining 2's (i.e. 2 digits)The last digit can only be the last 2 (i.e. 1 digit)So, we have:
[tex]Case\ 3 = 9 * 10 * 3 * 1 * 2 * 1[/tex]
[tex]Case\ 3 = 540[/tex]
The total number of whole numbers is:
[tex]Total = 600 + 540 + 540[/tex]
[tex]Total = 1680[/tex]
Hence, there are 1680 6-digit whole numbers that the digits
