Answer:
"descends"
Step-by-step explanation:
The word descend means to move or fall downwards. If we were to think of the ladder as the y-axis of a coordinate grid we could see that as you move further down on the axis the numbers turn to negative which indicate that the word descend means that a negative integer should be used :)

5.5 ft
4 ft
16 ft
A. 16.5
B. 17.5
C. 20
D. 22
Answer:
22ft
Step-by-step explanation:
Find the diagram attached
Since the triangles are mirror images of each other, this shows that they are similar triangles
Taking the ratio of the sides of the triangle and equating it to a constant, we will have;
5.5/4 = x/16
Cross multiply
4 * x =5.5 * 16
4x = 88
x = 88/4
x = 22ft
Hence the required value of x is 22ft
The rectangle below has an area of zº +82 + 15 square meters and a width of 2 + 3 meters.
What expression represents the length of the rectangle?
Length
2 +3
2° +8x + 15
Length
meters
Answer:
(x+5) metres
Step-by-step explanation:
correct question
The rectangle below has an area of x^2+8x+15 square meters and a width of x+3 meters. What expression represents the length of the rectangle?
Area of the rectangle = Length * width
Factorize the area
A(x) = x^2+8x+15
A(x) = x^2+3x+5x+15
A(x) = x(x+3) + 5(x+3)
A(x) = (x+3)(x+5)
Since the width is x+3, the length of the rectangle will be (x+5) metres

There are six households in a rural community. Each household earns $40,000 per year. Suppose that a new resident builds a mansion in the community and that the income in the new household is $4 million per year. After the new resident arrives, the median household income has _____, and the mean household income has _____. increased; increased not changed; increased not changed; not changed increased; not changed
Answer:
Median income has not changed
Mean income has increased
Step-by-step explanation:
Initial number of houses = 6
Earning per household = $40,000
The initial mean :
$(40,000 * 6) / 6 = $40000
Initial median :
40000, 40000, 40000, 40000, 40000, 40000
= 1/2(n+1)th term,
Median = 40000
A 7th household earns 4,000,000
Mean = ((40000*6) + 4,000,000) / 7 = $605,714
Median = 1/2(n+1)th term
40000, 40000, 40000, 40000, 40000, 40000, 4000000
Median = 4th term = 40000

Answer:
3) ΔQRS ~ ΔQFG
5) ΔRST ~ ΔGFE
Step-by-step explanation:
3) Shortest to longest, the side ratios are ...
RQ : QS = 6 : 12 = 1 : 2 (reduced)
FQ : QG = 2 : 4 = 1 : 2 (reduced)
ΔQRS ~ ΔQFG
__
5) FE : EG : GF = 18 : 24 : 26 = 9 : 12 : 13 (reduced)
ST : TR : RS = 27 : 36 : 39 = 9 : 12 : 13 (reduced)

The sum of Alex and John's money is $48. Alex has $3 more than twice the amount John has. How much money do they each have?
Answer:
John has $15 and Alex has $33Step-by-step explanation:
a systems of equations can be made from the information on the problem
x+y=48
x=2y+3
since x= 2y+3 substitute 2y+3 in the firat equation to get:
(2y+3)+y=48 -> 3y+3=48 -> 3y=45 -> y=15
plug in 15 for y in the second equation to solve for x
x+15 =48 --> x=33
