Answer:
-3/8
Step-by-step explanation:
(-2/3)³ / x = (9/8) -²
-2³/3³ = (2³/3²)²x
-2³/3³ = (2^6/3^4)x
-2³ × 3^-3 × 3^4 × 2^-6 = x
-2^-3 × 3 = x
x = -3/8

If im going 30 km per hour and i need to go 500 metres how long would it take
Answer:
1 minute
Step-by-step explanation:
1km = 1000m
30km = 30000m
30km ÷ 60 = 500m
it takes one hour to go 30km or a ratio of 30km to 1hour. 1hour is also 60minutes. 30:60
divide both sides by 60 gets 500m and the amount of time to go that distance 1 minute
Answer:
1/60 hr or 1 minute
Step-by-step explanation:
30 km per hour
30 km : 1 hr
convert 500 metres to km
1 km = 1000 metres
500 ÷ 1000 = 0.5 km
using ratios
30 km : 1 hr
0.5 km : x hr
to get from 30 to 0.5 multiply by 1/60 ( we got this from doing 0.5 ÷ 30) , so do the same to the other side
1 hr × 1/60 = 1/60 hr
you can convert to minutes = 1/60 × 60 = 1 minute

Answer:
A) x = 0, y = 14
Step-by-step explanation:
Line A: y = 6x + 14
Therefore, the slope of line A = 6
If Line B is perpendicular to Line A, then the product of their slopes is -1.
⇒ slope of Line B = [tex]-\dfrac16[/tex]
Given Line B passes through point (2, 13 2/3).
Use slope-point form of linear equation to find equation for Line B:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-13 \frac23=-\dfrac16(x-2)[/tex]
[tex]\implies y=-\dfrac16x+14[/tex]
Solution of system is the point where the lines intersect.
From inspection of the equations of the lines, the point of intersection is (0, 14)

Bamboo plants grow rapidly. A bamboo plant is 121 inches tall. Tomorrow it will be 134 inches tall, the next day it will be 147 inches tall, and on the next day it will be 160 inches tall. Write an explicit formula to represent the height of the bamboo plant as an arithmetic sequence. How tall will the plant be in 15 days?
The height of the bamboo plant after 15 days is 316 inches.
What is the height of the plant in 15 days?
In order to determine the formula that represents the rate of growth of the bamboo plant, we have to determine the inches of growth per day.
Rate of growth per day = 134 - 121 = 13 inches
The height of the bamboo plant = 121 + 13h
Where h is the number of days
Height in 15 days = = 121 + (13 x 15)
= 316 inches

help me with geometry please
Answer:
y= 95.
180°-120°=60° (adding 120° with x should give you 180°)
x=60°
25°+60°=85°
180°-85°=95
Answer:
y=95
Step-by-step explanation:
we know that the triangle angles sum is 180°
to find Y you should find x
we are going to find x, we know that a straight angle is 180, to find the x you should:
[tex]120+x=180[/tex]
move 120 to the other side with a negative sign:
[tex]x=180-120\\x=60[/tex]
angle [tex]x=60[/tex]
now we know enough angles to find y:
[tex]25+60+y=180[/tex]
25 is given in the picure and 60 is the x angle while 180 is the sum of a triangle angles, we have to flip the equaton to find y:
[tex]25+60+y=180\\85+y=180\\y=180-85\\y=95[/tex]

Answer:
y = 14 [tex](2)^{x}[/tex]
Step-by-step explanation:
Find a and b by substituting the points into the equation
using (0, 14 ) , then
14 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then
14 = a × 1 ⇒ a = 14
y = 14 [tex]b^{x}[/tex]
using (6, 896 )
896 = 14 [tex]b^{6}[/tex] ( divide both sides by 14 )
64 = [tex]b^{6}[/tex] ( take the sixth root of both sides )
b = [tex]\sqrt[6]{64}[/tex] = 2
Then

Answer:
A: $250B: $600, earns more interestStep-by-step explanation:
The simple interest formula is ...
I = Prt . . . . . r is the interest rate, t is the number of years
Solving for P, we have ...
P = I/(rt)
Account A6 months is 1/2 year, so the principal is ...
P = $4.38/(0.035×1/2) = $250.2857...
Rounded to the nearest dollar, the principal invested is $250.
__
Account BUsing the same approach, for 18 months, t = 18/12 = 3/2 = 1.5.
P = $20.70/(0.023×1.5) = $600
The principal in Account B is $600.
__
First Month's Interest
Using the interest formula, the first month's interest in each account is ...
A: I = 250×0.035×1/12 = $0.73
B: I = 600×0.023×1/12 = $1.15
Account B earns more interest in the first month.
