Answer:
Money saved by Jade = € 25
Money saved by May = € 30
Money saved by Nel = € 60
Step-by-step explanation:
Money saved by Jade = € x
Money saved by May = x + 5
Money saved by Nel = 2* (x + 5) = 2*x + 2*5 = 2x + 10
Total = € 115
x + x + 5 + 2x + 10 = 115
x + x + 2x + 5 + 10 = 115
Combine like terms
4x + 15 = 115
Subtract 15 from both sides
4x = 115 - 15
4x = 100
Divide both sides by 4
x = 100/4
x = € 25
Money saved by Jade = € 25
Money saved by May = 25+ 5 = € 30
Money saved by Nel = 2*25 + 10 = 50 + 10 = € 60
Answer:
Jade=€25
May=€30
Nel=€60
Step-by-step explanation:
Since Nel has 2 units, May has one and you do not know Jane but it is only €5 less, you want to plus 5 to make Jane have one unit like May, so:
115+5=120 (4 units）
120 divide 4= 30 (1 unit)
Jade=30-5=€25
May=€30
Nel=30x2=€60
Hope this helps! Thanks.
. A bakery opened yesterday with its daily supply of 40 dozen rolls. Half of the rolls were sold by noon, and 80 percent of the remaining rolls were sold between noon and closing time. How many dozen rolls had not been sold when the bakery closed yesterday
16 dozen
Step-by-step explanation:
a dozen=12
x=(40×12)/2
=240 rolls : are sold by noon

How do we say that the cost of rice and the quantity of rice we purchase are in inverse proportion?
Answer:
Step-by-step explanation:
I don't think they are. It sounds like a direct proportion to me. The more rice you buy, the higher the cost.
Cost = k * quantity.
That would be the most general formula.

At a competition with 7 runners, medals are awarded for first, second, and
third places. Each of the 3 medals is different. How many ways are there to
award the medals?
Decide if this is a permutation or a combination, and find the number of ways
to award the medals.
Answer:
35 different combinations
Step-by-step explanation:
This would be a combination because the same person cannot get all three medals so permutation is not the correct way to calculate this. We use the formula C(n,r)=(nr)=n!(r!(n−r)!)=? where n is the number of total objects and r is the number of objects taken from the total.

Find the midpoint of the segment with the given endpoints.
(-10.8) and (2.2)
Answer:
(-4,5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinate of the endpoints and divide by 2
(-10 +2)/2 = -8/2 = -4
To find the y coordinate of the midpoint, add the y coordinate of the endpoints and divide by 2
(8 +2)/2 = 10/2 = 5
(-4,5)
Answer:
(-4 , 5)
Step-by-step explanation:
(x₁ , y₁) = (-10 , 8) & (x₂ , y₂) = (2 , 2)
[tex]Midpoint = (\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2})\\\\[/tex]

Answer:
p=-7
Step-by-step explanation:
-11+10(p+10)=4-5(2p+11)
Firstly, expand the bracket
-11+10p+100=4-10p-55
Next, you collect like terms
10p+10p=4-55-100+11
20p=-140
Divide through by the coefficient of p
20p/20=-140/20
p=-7
(Last one is point W)PLEASEEE HELP DUE SOON
Part 1
Answers: point Q, point R, point S
-----------------
Explanation:
All three points mentioned are on the same straight line; hence they are collinear.
=======================================================
Part 2
Answer: Point T or point W
Pick one of those answers only
-----------------
Explanation:
Notice how point W is not on the line shared by points Q, R, and S. The same can be said about point T with that line.
So we would say that the set {T, Q,R,S} is not a collinear set of points. We could also say {W, Q,R,S} is also not collinear.

The correct answer is : -0.7
A correlation coefficient is a statistical indicator of how well changes in one variable's value predict changes in another. There is a common tendency to assume that a change in one variable must be the result of a change in the other when the fluctuation of one variable predicts a similar fluctuation in another variable with high accuracy.
Correlation does not necessarily indicate cause, though. For instance, there might be an unidentified factor that has a similar impact on both variables. When it comes to consumer data patterns, being able to distinguish between correlation and causation can be useful and provide insightful information. In the context of marketing, the beer and diapers example is frequently used to illustrate this.
The correlation coefficient is close to: -0.7 (negative because there is an inverse relationship)
Based on this information, we can conclude that Amélie's cake sales are affected by the daily temperature.
Therefore, the final answer is : -0.7.

Xian and his cousin Kal both collect stamps. Xian has 52 stamps, and Kal has 68 stamps. The boys recently
joined different stamp-collecting dubs. Xian's club will send him 20 new stamps per month. Kai's club will
send him 16 new stamps per month. After how many months will Xlan and Kal have the same number of
stamps? How many stamps will each have?
Answer:
In 4 months, they will both have 132 stamps.
Step-by-step explanation:
Let x = # of months
52 + 20x = 68 + 16x
4x = 16
x = 4
Plug x value into both expressions and see if it checks out
52 + 20(4) = 68 + 16(4)
52 + 80 = 68 + 64
132 = 132
A goat is grazing outside of a rectangular barn that has dimensions 20 ft by 30 ft.
He's tied to a corner of the barn with a 12 ft rope. Find the grazing area of the goat.
Answer:
108π ft² or 339.29 ft²Step-by-step explanation:
Refer to attached picture.
The grazing area of the goat is 3/4 of area of circle with 12 ft radius:
A = 3/4(πr²) = 3/4(π*12²) = 108π or 339.29 ft²Tied to the corner
Means 1part among 4parts of circle or a quarter area
