V(t)=27,500(0.90)t. Find the value after 11 years

Alika [10]

Answer:

8,630

Step-by-step explanation:

$V(t) = 27,500(0.90)^t$

$V(11) = 27,500(0.90)^{11}$

$V(11) = 27,500(0.3138)$

$V(11) = 8,630$

What is 400,000 times 200 in scientific notation

aniked [119]

If you move the decimal point left until it is just to the right of the most-significant digit, the number of places you moved it is the power of ten that your new number is multiplied by.

$400,000=4\times 10^{5}\\200=2\times 10^{2}$

Then multiplication can proceed in the usual way, taking into account the rules of exponents.

$4\cdot 10^{5}\times 2\cdot 10^{2}=8\cdot 10^{(5+2)}\\\\=8\cdot 10^{7}$

Find the measure of angle ABC

victus00 [196]

First we need to find x so 6x+8x+6x= 180
20x=180 and x= 9

So A= 6*9= 54
B= 8*9= 72
C= 6*9= 54

Solve for x 4.5 (8 - x) + 36 = 102 - 2.5 (3x + 24)

CaHeK987 [17]

Answer:

x = -10

Step-by-step explanation:

expand

simplify 36 - 4.5x + 36 to -4.5x + 72

simplify 102 - 7.5x - 60 to -7.5x + 42

add 7.5x to both sides

simplify -4.5x + 72 + 7.5x to 3x + 72

subtract 72 from both sides

simplify 42 - 72 to -30

divide both sides by 3

simplify 30/3 to 10

Answer: x = -10
