He did not eat 4 of the brownies.  This is because 2/6 is equivalent to 4/12.  That means he couldn't have eaten 4 of them. Hope that helps!!

“Dad”couldn’t eat 4 since 2/6 is equivalent to 4/12 and the problem states that Mary had cooked a dozen brownies so overall he couldn’t eat 4 brownies

Carla wants to start a college fund for her daughter Lila. She puts $63,000 into an account that grows at a rate of 2.55% per ye
Oksanka [162]

Answer:

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 63000

r = 2.55% = 2.55/100 = 0.0255

n = 12 because it was compounded 12 times in a year.

Therefore, function, C(t), that represents the amount of money in the account t years after the account is opened is

C(t) = 63000(1 + 0.0255/12)^12t

C(t) = 63000(1.002125)^12t

For C(t) = 100000,

100000 = 63000(1.002125)^12t

100000/63000 = (1.002125)^12t

1.587 = 1.002125)^12t

Taking log of both sides

Log 1.587 = log 1.002125)^12t

Log 1.587 = 12tlog 1.002125)^

0.2005 = 12t × 0.00092

0.2005 = t × 0.01104

t = 0.2005/0.01104

t = 18.16 years

Use foil (a + 3)(a - 2)
blsea [12.9K]

Answer:

\left(a+3\right)\left(a-2\right)=a^2+a-6=

Step-by-step explanation:

Given expression is \left(a+3\right)\left(a-2\right).

Now we need to multiply this using FOIL.

F = First =\left(a\right)\left(a\right)= a^2

O = Outside =\left(a\right)\left(-2\right)= -2a

I = Inside =\left(3\right)\left(a\right)= 3a

L = Last =\left(3\right)\left(-2\right)= -6

Hence we get :

\left(a+3\right)\left(a-2\right)=a^2-2a+3a-6=a^2+a-6=

A car advertisement claims that a certain car can accelerate from rest to 70 km/hr in 7 seconds find the car acceleration
iVinArrow [24]

Answer:

acceleration \approx 2.78\,\,\frac{m}{s^2}

Step-by-step explanation:

The acceleration is the change in velocity per unit of time.

Therefore to have this rate in appropriate units that can combine, we re-write the change from 0 to 70 km/h in meters per second using:

70 \frac{km}{h} = \frac{70000}{3600} \frac{m}{s}

so in this case the acceleration becomes:

accel=\frac{change\,\,vel}{change\,\,time} =\frac{70000m}{3600\,*7\,s^2} \approx 2.78\,\,\frac{m}{s^2}
