Hi!
We will find the monthly budget using proportions, like this:
15% = 0,15___________600$
100% = 1_____________x$
__________________________
x = (600*1)/0,15
x = 600/0,15
x = 4000
Their monthly budget is 4000$.
Hope this helps!
Total amount of gas purchased by Ivy's father in the first week = 22.5 gallons
total amount of gas purchased by Ivy's father in the second week = 19.71 gallons
Let us assume the amount of gas purchased by Ivy's father in the third week = x
The total quantity of gas purchased in 3 weeks by Ivy's father = 61.75 gallons
Then
22.5 + 19.71 + x = 61.75
42.21 + x = 61.75
x = 61.75 - 42.21
= 19.54 gallons
So 19.54 gallons of gas was bought by Ivy's father in the third week
Mean: 4 [(4+8+6+4+4+1+1)/7]
median: 4 [1 1 4 4 4 6 8 the number in the middle is 4
mode: 4 [ there are 3 fours which is the most out of all the numbers]
range: 7 [8-1=7]
Answer:
B: (-4, 22)
Step-by-step explanation:
for these types of problems, you just need to plug in the values
A: y= -4(-4) + 6 = 22 — NOT 10
B: y= -4(-4) + 6 = 22 — CORRECT
C: y= -4(1) + 6 = 2 — NOT 10
D: y= -4(1) + 6 = 2 — NOT -2
The pattern is formed a geometric sequence
The nth term of the sequence is 
Step-by-step explanation:
The formula of the nth term of a geometric sequence is:
, where
- a is the first term
- r is the common ratio between the consecutive terms
∵ The pattern is 3 , 9 , 27 , 81 , 243
∵ 9 ÷ 3 = 3
∵ 27 ÷ 9 = 3
∵ 81 ÷ 27 = 3
∵ 243 ÷ 81 = 3
- There is a common ratio 3 between each two consecutive terms
∴ The pattern is formed a geometric sequence
∵ The first term is 3
∴ a = 3
∵ The common ratio is 3
∴ r = 3
- To find the nth term substitute a and r in the formula above
∵
∴ 
- Remember we add the powers of the same base with multiplication
∵ 3 × 
= 
∴ 3 × = 
∴
∴ The nth term of the sequence is
