Answers:
- x = 21.25
- y = 22.5
- z = 23.75
=============================================================
Work Shown:
AP = arithmetic progression, which is the same as arithmetic sequence
d = common difference
- x = 20+d
- y = 20+2d
- z = 20+3d
Notice how we scale up the d terms d, 2d, 3d, counting up by 1 each time.
So that must mean 25 is the same as 20+4d
20+4d = 25
4d = 25-20
4d = 5
d = 5/4
d = 1.25
and therefore,
- x = 20+d = 20+1.25 = 21.25
- y = 20+2d = 20+2*1.25 = 22.5
- z = 20+3d = 20+3*1.25 = 23.75
We could convert these to fraction form, but I find decimal form is easier in this case.
Step-by-step explanation:
Step one:
given data
we are told that she wants her balance to be at least $100
y=100-------1
the expression relating her current balance and spending rate is
let y be the total and m be the number of months
y=330-11m----------2
Required
the number of months m
equating 1 and 2 we have
100=330-11m
11m=330-100
11m=230
m=230/11
m=20.9
m=21 approx
This means that she will keep her account open for 1 year 9 months
Given:
The reasoning problem is
42=164, 73=499, 51= 251, 29=?
To find:
The missing value.
Solution:
In the given reasoning problem, we need to square each digit then write them combinedly.
On combining these two, we get
Similarly,
Using this pattern, we need write the square of 2 and 9 combinedly to find the value of 29.
Therefore, the missing value is 481.
Answer:
negative 0.5 less-than-or-equal-to z less-than-or-equal-to 0.5
Step-by-step explanation:
its the peak of the graph
I think 6 is 36/100 I'm not real sure if that's the answer your looking for but if you divide it that's what you get
