Answer:

Step-by-step explanation:

To find x, add together the intercepted arcs, 106 and 174, and then divide that number in half. 174 + 106 = 280, and half of 280 is 140.

Exactly 120 tickets were sold for a concert. The tickets cost $12 each for adults, $10 each for seniors, and $6 each for childre

Gemiola [76]

A=adult tickets
c=chlderenticekts
s=sinior tickets

a=c

a+c+s=120
2a+s=120

total made is 1100
12a+6c+10s=1100
sub
a=c
12a+6a+10s=1100
add
18a+10s=1100

multiply first equation by -9 and add to other equation

-18a-9s=-1080
18a+10s=1100 +
0a+s=20

s=20
20 senior tickets were sold

answer is B

Kenji simplifies 3^5 x 4^ 5and gets the result 12^10, but Darlene is not sure. Is Kenji correct? Justify your answer.

That's a question about exponentiation.

Answer:

Kenji is wrong because he does not aply the porperty correctly.

Step-by-step explanation:

A exponetiation has this form:

$\boxed{a^b}$

<em>a </em>is the base

<em>b</em> is the power or exponent

To understand that situation it's important to know a property about exponentiation. When we have a multiplication with the same exponent and diferent bases, the result is the multiplication of the bases with the same exponent. Let's see this above, in mathematical language:

$\boxed{a^b \cdot c^b = (a\cdot c) ^b}$

Examples:

$2^3 \cdot 8^3 = (2 \cdot 8) ^3 = 16^3$

$10^9 \cdot 23^9 = (10 \cdot 23) ^9 = 230^9$

Now, we can say why Kenji is wrong. It's easy simplify $3^5 \cdot 4^5$ ! We know that the result is $(3 \cdot 4) ^5 = 12^5$ , but Kenji multiplied the bases and added the exponents, that's why he is wrong.

I hope I've helped. ^^

Enjoy your studies! \o/
