The ratio of money in Terry's bank account to Faye's bank account was 3:7. Terry then put £220 in his account and Faye withdrew £300 from her account. They now had the same amount in their accounts. How much did Terry initially have?
Answer:
Terry initially had £390
Step-by-step explanation:
The ratio of the original amount is 3:7
Let the original amount Terry has be t and the original amount Faye has be f
3/7 = t/f
or simply 3f = 7t ••••••(i)
Terry putting 220 means he now has
t + 220
Faye withdrew 300
He now has f-300
These values are equal
t + 220 = f-300
f = t+220+300
f = t + 520 ••••••(ii)
Put ii into i
3(t + 520) = 7t
3t + 1560 = 7t
7t-3t = 1560
4t = 1560
t = 1560/4
t = 390

The side of a cube is increasing at a rate of 2 kilometers per hour. At a certain instant, the side is 1.5. What is the rate of change of the volume of the cube at that instant (in cubic kilometers per hour)?
Answer:
dV/dt = 13,5 [Km³/h]
Step-by-step explanation:
The volume f the cube is:
V = x³ where x is a side of the cube, then tacking derivatives with respect to time on both sides of the equation
dV/dt = 3*x² dx/dt
dx/dt = 2 km/h
at the time when the side x = 1,5 Km
dV/dt = 3* (1,5)²*2 [km³/h]
dV/dt = 13,5 [Km³/h]

1/2 ( x - 4 ) = 1/3 ( x + 2)
pls help me
Answer:
x=16
Step-by-step explanation:
1/2 ( x - 4 ) = 1/3 ( x + 2)
distribute both sides
1 /2 (x−4)= 1/ 3 (x+2)
( 1 /2 )(x) + ( 1/ 2 )(−4) =( 1 /3 ) (x)+( 1/3 )(2)(Distribute)
1 /2 x+−2= 1 /3 x+ 2 /3
1 /2 x+−2= 1 /3 x+ 2 /3
Step 2: Subtract 1/3x from both sides.
1/2x -2 -1/3 x
x= 1 /3 x + 2/3 − 1/ 3 x
1 /6 x−2= 2/ 3
Step 3: Add 2 to both sides.
1 /6 x −2+2= 2/ 3 +2
1 /6 x = 8 /3
Step 4: Multiply both sides by 6.
6*( 1/6 x) =6*( 8 /3 )
x=16

proportional constant
Answer:
The value of the proportionality constant (y to x) is: 3/10
Step-by-step explanation:
We know the slope of any graph where 'y' varies directly with 'x' gives us the constant of proportionality 'k'.
i.e. y = kx
and k = y/x
Given the points
(100, 30)(300, 90)(500, 150)We know that the proportionality constant (y to x) is:
k = y/x
For the point (100, 30)
k = 30/100=3/10
For the point (300, 90)
k = 90/300=3/10
For the point (500, 150)
k = 150/500=3/10
As the value of proportionality constant (y to x) is the same.
i.e. k = 3/10
Thus, the value of the proportionality constant (y to x) is: 3/10

Who spent more of their allowed on pizza? 2/5 and 0.25
Answer:
2/5, because 2/5 is bigger than 0.25.
Step-by-step explanation:
Answer:
2/5 spent more.
Step-by-step explanation:
Well, 2/5 converted to fraction is 0.40 since 2÷5=0.4.
And 0.40 is more than 0.25.
So 2/5 spent more of their allowance.

Answer:
The amount will be "$3655.21".
Step-by-step explanation:
The given values are:
Principle,
P = $3000
Interest rate,
r = 10% i.e., 0.1
Number of times interest,
n = 4
Time,
t = 2 years
As we know,
⇒ [tex]A=P[1+\frac{r}{n} ]^{tn}[/tex]
On putting the values in the above formula, we get
⇒ [tex]=3000[1+\frac{0.1}{4} ]^{2\times 4}[/tex]
⇒ [tex]=3000[1+0.025]^8[/tex]

y + 1 = 4(x - 2)
y = 4x + 11
8x - 2y = 6
Step-by-step explanation:
Following equations are parallel to the graph 4x - y = 6, because their slopes are equal (4).
y + 1 = 4(x - 2)
y = 4x + 11
