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

Given the points X(-9, 2) and Y(5, -4), find the length of XYXY. Round to the nearest hundredth.
Answer:
15.23
Step-by-step explanation:
the length of XY =√(5+9)²+(-4-2)²
=√14²+(-6)²
=√196+36
=√232
= 15.23

The table shows the estimated number of deer living in a forest over a five-year period. Are the data best represented by a linear, exponential, or quadratic model? Write an equation to model the data.
A. exponential; y = 89 • 0.62x
B. linear; y = 0.62x + 89
C. quadratic; y = 0.62x2 + 89
D. quadratic; y = 89x2 + 0.62
Answer:
A. exponential; y = 89 • 0.62x
Step-by-step explanation:
exponential; y = 89 • 0.62^x
Answer:
Option B exponential y = 89 · 0.62x
Step-by-step explanation:
The table shows the estimated number of deer living in a forest over a five year period.
Year Number of deers
0 89
1 55
2 34
3 21
4 13
Now we have to find the model representing this situation. Difference in number of deer, in the forest.
We can see there is a common ratio between each successive term r = = 0.618
r = = 0.618
so it can be represented by an exponential model.

Maggie needs to spend at least six hours each week practicing the piano. She already practiced 3 1/4 hours this week. She wants to split the remaining practice time evenly between the last two days of the week. Which inequality best determines the minimum number of hours she needs to practice on each of the two days.
Answer:
Let X equal the remaining time she needs to practice.
You would have 2x
The combined total needs to be 6 hours or greater.
You need to add the amount she already practiced to 2x.
Now you have: three and one fourth + 2x
This needs to be greater than or equal to 6.
Ans:- three and one fourth + 2x ≥ 6

The first term of an A.P. is unity and the common difference is 4, which of the following will be a term of this A.P. (a ) 4551 (b ) 10091 ( c ) 7881 ( d ) 13531
Answer:
c
Step-by-step explanation:
first term=1
common d=4
nth term=a+(n-1)d
7881=1+(n-1)4
7881=1+4n-4
7884=4n
n=1971
Starting with n = 0, the n-th term in the sequence is
4n + 1
so any number in the sequence must have a remainder of 1 when divided by 4.
We have
4551 = 1137×4 + 3
10091 = 2522×4 + 3
7881 = 1970×4 + 1
13351 = 3382×4 + 3

Joy drinks 4 bottles of water per day. Each bottle contains
16.5 fluid ounces. How many fluid ounces of water does
she drink per day?
a) 66 fluid ounces
b) 68 fluid ounces
c) 660 fluid ounces
d) 680 fluid ounces
Answer:
A) 66
Step-by-step explanation:
I have no explanation to this but hope it's help
Answer:
a) 66 fluid ounces
Step-by-step explanation:
it's easy
all you have to do is multiply the amount of bottles Joy drinks in a day (in this case 4) with the amount of fluid ounces contained in each bottle she's drinking (in this case 16.5)
so in other words
4 x 16.5 = 66

(1+sin2A+cos2A)^2=4cos^2A(1+sin2A)
Answer:
(1+sin2A+cos2A) ^2=4cos^2A(1+sin2A)
Step-by-step explanation:
Here,
L.H.S=(1+sin2A+cos2A)^2
=(1+2sinAcosA+2cos^2A-1)^2
=(2sinAcosA+2cos^2A)^2
={2cosA(sinA+cosA)}^2
=4cos^2A(sinA+cosA)^2
=4cos^2A(sin^2A+2sinA.cosA+cos^2A)
=4cos^2A(sin^2A+cos^A+2sinAcosA)
=4cos^2A(1+sin2A)
=R.H.S
Hence,L.H.S=R.H.S.
(1+sin2A+cos2A)^2=4cos^2A(1+sin2A).
proved.

35 is 26% of what number?
Answer:
134.61 is the answer . hope This helps
Answer:
The answer is 134.61
Step-by-step explanation:
We have, 26% × x = 35
Or, 26/100 × x = 35
We have: x = 35 × 100/26
35×100 = 3,500
3,500 ÷ 26 = 134.61
x = 134.61
If you use a calculator, simply put 35×100÷26, which will give you the answer.
Does the graph represent a function? Khan Academy
Answer:
yes
Step-by-step explanation:
try using a vertical line, if you move the vertical line across the graph and the line touches the graph only at one point, than it means it is a function
Answer:
This graph represents a function
Step-by-step explanation:
By its definition, a function is a relation or a correlation between two sets (groups) of values where every input corresponds to only one output. What this means is that every input in a function can only have one output. This characteristic results in a unique property in the graph of a function, that is, the verticle line test. The verticle line test states that when one draws a line through the graph of a function, the line can only intersect the graph in exactly one place in the function. If the line intersects the graph in more than one place, then the graph does not represent a function. In the given situation, any verticle line drawn on the graph only intersects the graph in one place, thus the graph represents a function.
The total length of the stage is 76 feet. An actor starts at point A then stops at point B before disappearing through the trap door. How far does he walk across the stage?
Answer:
since the distance from the outside edges is 26 1/2 feet, divide that by 2 to get the distance from the center to the edge ( 26 1/2 / 2 = 13 1/4 feet)
the stage is 76 feet so divide that by 2 to find the center 76/2 = 38 feet
now subtract the 13 1/4 from 38
38 - 13 1/4 = 24 3/4 feet from the side of the stage to the edge of the trap door
a little easier way would be to subtract the 26 1/2 from 76 and then divide by 2
76-26 1/2 = 49 1/2 / 2 = 24 3/4

B. 25 degree

d. 75 degree
Step-by-step explanation:
shown in photo.
Mark me brain list if it help you
Answer:
a = 65°
b = 25°
c = 25°
d = 75°
Step-by-step explanation:
60 + a + 55 = 180 (Angles of a straight line)
a + 115 = 180
a = 180 - 115
a = 65°
a + b + 90 = 180 (Interior angles of a triangle add up to 180°)
65 + b + 90 = 180
b + 155 = 180
b = 180 - 155
b = 25°
b = c (Vertically opposite angles are equal)
c = 25°
d + 15 = 90 (Complementary angles)
d = 90 - 15
d = 75°
