2 times 12 minus 14 divided by 2 = ?

Answers

Answer 1

Answer: $2*12- (14)/(2)$

$2*12=24$

$24- (14)/(2)$

$(14)/(2) =7$

$24-17=7$

- - Final answer: 7

Answer 2

Answer:

Answer:

This Would Equal 5!

Step-by-step explanation:

2*12= 24

Then, 24-14=10

Finally, 10/2=5

Gary bought a car for $40,000. If V = 40,000(.85)t represents the value of the car after t years, how long will it take the car to be worth less than one-fourth of its purchase price? A) 4 years B) 6 years C) 8 years D) 9 years

Answers

Answer:

D) 9 years.

Step-by-step explanation:

We have been given that Gary bought a car for $40,000 and equation $V=40,000(0.85)^t$ represents the value of the car after t years.

First of all we will find the one-fourth of 40,000.

$\text{One-forth of car's purchase price}=(\$40,000)/(4)$

$\text{One-forth of car's purchase price}=\$10,000$

To find the time it will take the car to be worth less than one-fourth of its purchase price, we will substitute V=10,000 in our given equation.

$10,000=40,000(0.85)^t$

Let us divide both sides of our equation by 40,000.

$(10,000)/(40,000)=(40,000(0.85)^t)/(40,000)$

$0.25=0.85^t$

Let us take natural log of both sides of our equation.

$ln(0.25)=ln(0.85^t)$

Using natural log property $ln(a^b)=b*ln(a)$ we will get,

$ln(0.25)=t*ln(0.85)$

$(ln(0.25))/(ln(0.85))=(t*ln(0.85))/(ln(0.85))$

$(-1.3862943611198906)/(-0.1625189294977749)=t$

$8.530048563597=t$

Upon rounding our answer to the nearest year we will get,

$t\approx 9$

Therefore, it will take 9 years the car to be worth less than one-fourth of its purchase price and option D is the correct choice.

Find the coordinates of the midpoint of a segment with the endpoints (16,5) & (28, -13)

Answers

The midpoint can be obtained by taking the averages of the x-coordinate and the y-coordinate. The averages obtained are the new coordinates for the midpoint. This is shown below:

x-coordinate:

X = (16 + 28)/2
X = 22

y-coordinate:

Y = (5 + -13)/2
Y = -4

Therefore, the midpoint has the coordinates M (22 , -4)

anne has 24 more cards than devi. anne finds that 3/5 of devi's cards are equal to 1/2 of her cards. how many cards does anne have?

Answers

if 1/2 of 24 are 3/5 of devi's cards, then 1/2(24)=3/5x, 12=0.6x, 20=x. Devi has 20 cards

ok so A(Anne) = D(Devi) + 24
and 1/2A = 3/5D
which is equal to A = 6/5D
which means that the 1/5 extra must = 24
so A = 6*24
A = 144

Please help I've been stuck on this question for a while now. How do I solve (1/2)^4 (1/2)^-2? It has to do with Multiplying and Dividing Expressions with Exponents. Please show work so I may figure it out on my own.

Answers

The value of the expression is $0.25$

Explanation:

The expression is $\left((1)/(2)\right)^(4)\left((1)/(2)\right)^(-2)$

Since, the base of the expression is the same. Then, by "product rule", when multiplying two powers that have the same base, you can add the exponents.

Thus, we have,

$\left((1)/(2)\right)^(4)\left((1)/(2)\right)^(-2)=\left((1)/(2)\right)^(4-2)$

Adding the exponents, we have,

$\left((1)/(2)\right)^(4)\left((1)/(2)\right)^(-2)=\left((1)/(2)\right)^(2)$

Applying exponent rule, $\left((a)/(b)\right)^(c)=(a^(c))/(b^(c))$ , we have,

$\left((1)/(2)\right)^(2)=(1^(2))/(2^(2))$

Simplifying, we get,

$(1)/(4)$

Dividing, we have,

$0.25$

Thus, the value of the expression is $0.25$
