Yara multiplies and divides a certain number by the same
Butoxors [25]

For this case we have to:

x: Represents the unknown number

y: Represents the exponent of base 10

So, considering a system of equations we have:

x * 10 ^ y = 40,000\\\frac {x} {10 ^ y} = 0.000004

From the first equation we have:

10 ^ y = \frac {40,000} {x}

Substituting in the second equation:

\frac {x} {\frac {40,000} {x}} = 0.000004\\\frac {x ^ 2} {40,000} = 0.000004\\x ^ 2 = 40,000 * 0.000004\\x ^ 2 = 0.16\\x = \pm \sqrt {0.16}

We choose the positive value:

x = 0.4

So, the number is 0.4.

So:

10 ^ y = \frac {40,000} {0.4}\\10 ^ y = 100,000\\y = 5

Thus, the exponent is 5.

Answer:

Yara use 0.4 and10 ^ 5

The town Atlanta needs $14,000 for a new playground Lanzetta Elementary school raise $5358 Lantana middle school race $2834 Atla
Elza [17]
Lanzetta Elem. raised 5358....round to 5,000
Lantana Mid. Sch raised 2834....round to 3,000
Atlanta High Sch. raised 4132...round to 4,000

they need 14,000...they have (5,000 + 3,000 + 4,000) = 12,000....so they will need (14,000 - 12,000) = 2,000 more....keep in mind, these are estimates...not exact answers

In the morning, the temperature was 15∘F. During the day, the temperature fell 37 degrees. Which expression shows how to find th
tino4ka555 [31]

Answer:

- 22°F

Step-by-step explanation:

Given that :

Morning temperature = 15°F

Change in temperature = fall by 37 degree

The temperature of the end of the day:

Morning temperature + (change in temperature)

Fall by 37° = decrease in temperature by 37° = - 37°

15°F + (-37°F)

15°F - 37°F

= - 22°F
