1,500/5=300.

Therefore 1/5 of $1,500 is $300.

$1,500 - $300 = $1,200.

So its price today would be $1,200.

$1500-\frac{1}{5}*1500=1500-300=1200$

From the initial amount, as much as it cost to be deducted at the beginning of one-fifth of that amount. The difference of these two will be sought after result. Above is the solution.

Which choice is equivalent to the expression below?

alekssr [168]

Answer: OPTION A

Step-by-step explanation:

We need to remember that Product of powers property, which states that:

$(a^m)(a^n)=a^{(m+n)}$

Let's check the options:

A. For $5^9*5^{\frac{9}{10}}*5^{\frac{6}{100}}*5^{\frac{9}{1000}}$ you can apply the property mentioned before. Then:

$5^{(9+\frac{9}{10}+\frac{6}{100}+\frac{9}{1000})=5^{9.969}$

(It is the equivalent expression)

B. Add the exponents:

$5^9*5^{(\frac{9}{10}+\frac{9}{10}+\frac{6}{1000})=5^{10.806}$

(It is not the equivalent expression)

C. For $5^9*5^{\frac{96}{10}}*5^{\frac{9}{100}}}$ you can apply the property mentioned before. Then:

$5^{(9+\frac{96}{10}+\frac{9}{100})=5^{18.69}$

(It is not the equivalent expression)

D. We know that $5^{9.969}=9,290,347.808$ and we maje the addition indicated in this option, we get:

$5^9+5^{\frac{9}{10}}+6^{\frac{6}{100}}=1,953,130.37$

(It is not the equivalent expression)

Jorge ordered 22 bottles of juice. Each bottle holds 6.32 ounces of juice.

Umnica [9.8K]

Answer: On the first one its either A or D. (I think)

Step-by-step explanation:

So what I did was I multiplied 22 and 6.32 together and got 139.04 and the closest estimate to that would be 160 because 39 is closer to 60 than 20 (A) and since its not 150 the estimate would be lower than higher. (D)

What is the value of x in the equation 2x+3y=36y when y=6?

jonny [76]

Answer:

y = 6 so

2x + 3y = 36y is equal to:

2x + 3*6 = 36*6

-> 2x + 18 = 216

We must now move 18 to the other side of the equation. As we do that, we also change it's sign to negative 18:

2x = 216 - 18

We simplify this

2x = 198

Now, that we got to this point, we know that 2x is equal to 198. To find x we must divide the both sides of the equation by two:

2x/2 = 198/2

And we get that

x = 99

A train traveling 50 mph left a station 30 minutes before a second train running at 55 mph. how soon did the second train overta

Finger [1]

<span>1st train DATA:
rate = 50 mph ; time = x hrs ; distance = rt = 50x miles

2nd train DATA:
rate = 55 mph ; time = (x-(1/2)) hrs ; distance = rt = 55(x-(1/2)) miles

Equation:
distance = distance
50x = 55(x-(1/2)
50x = 55x - (55/2)
-5x = -55/2
x = 11/2
x = 5 1/2 hrs (time at which the 2nd train overtakes the 1st train)
Hope this helps!</span>

The line segment has an endpoint (5,-6) and the midpoint is (-2,3). Find the other point.

gavmur [86]

Answer:

(-9,12)

Step-by-step explanation:

$Endpoint\:= (5,-6) = x_1,y_1\\Midpoint = \: (-2,3)=x\:,y\\\\x = \frac{x_1+x_2}{2}\\\\ -2 = \frac{5+x_2}{2} \\-4 = 5+x_2\\-4-5=x_2\\-9 =x_2\\\\y = \frac{y_1+y_2}{2} \\\\3 = \frac{-6+y_2}{2} \\6 = -6+y_2\\6+(6)=y_2\\6+6=y_2\\12=y_2\\x_2 ,y_2=(-9,12)$
