Solve the exponential equation. (½)x = 32

abruzzese [7]

Answer:

x = - 5

Step-by-step explanation:

Using the rule of exponents

• $a^{-m}$ ⇔ $\frac{1}{a^{m} }$

Given

$(1/2)^{x}$ = 32

$\frac{1}{2^{x} }$ = 32

$2^{-x}$ = $2^{5}$

Since the bases are equal, both 5, equate the exponents

Hence x = - 5

Mai runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take Mai to complete 4

Artyom0805 [142]

Answer:

$6.4$ minutes

Step-by-step explanation:

<u>Given information:</u>

- Track is 400m long

- Mai runs at a constant speed of 250 meters/minute

- - - - - -

To find how many minutes it takes for Mai to complete 4 laps, we need to find the total distance Mai is running for:

$400\times4=1600$ meters

To find how many minutes Mai is running for, we divide by the distance Mai travels per minute:

$1600\div250=6.4$ minutes

∴ Mai takes $6.4$ minutes to run 4 laps around the track.

Hope this helps :)

6•12 ÷ √36 -4 ÷2+(8-5)

saveliy_v [14]

Answer: 6•12 ÷ √36 -4 ÷2+(8-5) = -21

Step-by-step explanation:it's -33 because PEMDAS first perenthese 8 - 5 = 3 then exponents the square root of 36 is 6 then multiply and divide left to right we can multiply 6 times 12 which equals 72, then we divide 72 ÷ 6 = 12 and 12 • -4 = -48 and -48 ÷ 2 = -24 and then we add and subtract left to right -24 + 3 = -21, So the answer is -21.
