PLEASE HELP ASAPPP!!!!!!!!!!!!!!!

You need to multiply 13.4 by 5,880,000,000,000.
First, we change both numbers into scientific notation.

13.4 = 1.34 * 10^1
5,880,000,000,000 = 5.88 * 10^12

Now we multiply the numbers written in scientific notation.

1.34 * 10^1 * 5.88 * 10^12 =

= 7.8792 * 10^13

The answer is choice A.

If you got a 1.25% interest rate how long would you need to invest $6000 if you wanted to earn $105 in interest

gavmur [86]

Answer:

1.4 years

Step-by-step explanation:

Use the formula for simple Interest:

$I = P * r * t$

Where I is the interest gained (in your case $105),

P is the principal (in your case $6000),

r is the annual interest rate in decimal form (in your case 0.0125)

and t is the time (in years) you need to find.

Therefore, we $105 = 6000 * 0.0125 * t = 75 * t\\t = \frac{105}{75} = 1.4 years$ solve for "t" in the following equation:

Set up the equation for the following word problem and solve the equation. Let x be the unknown number. -26 times a number minus

Lelechka [254]

Answer:

Step 1 of 2:
-26x - 5 = x - 56

Step 2 of 2:
17/9 or 1.89

Step-by-step explanation:

1. Putting word statement in algebraic form

Step 1:
Let x be the unknown number ==> x is the unknown variable to be used in the equation and to be solved for

Step 2:
-26 times a number minus 5 ==> -26x - 5

Step 3:
is equal to 56 less than the number ==> = x - 56

Putting it all together:
-26x - 5 = x - 56

2. Solving the equation
-26x - 5 = x - 56

1. Subtract x from both sides:
-26x - 5 - x = x - x -56

-26x -x - 5 = -56

-27x - 5 = -56

2. Add 5 to both sides
-27x - 5 + 5 = -56+ 5

-27x = -51

x = -51/-27 (dividing both sides by -27)

x = 51/27 (negative divide by negative results in positive)

Reduce 51/27 by dividing numerator and denominator by 3

x = (51 ÷ 3)/(27 ÷ 3) = 17/9

= 1.88888.... = 1.89 rounded to two decimal places

I need help understanding this

ladessa [460]

Answer:

the first choice

Step-by-step explanation:

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true.

then it means if the events are independent then the probability is multiplying the probability of each event.
