Mathematics

The answer is 140.

If there are 140 hamburgers sold, and there were 2x as many cheeseburgers sold, that adds up to 420.

140 x 2 = 280 (Cheeseburgers)
So there were 280 cheeseburgers sold.

280 (Cheeseburgers) + 140 (Hamburgers) = 420 altogether.

Hope this helps!

(X+8)(x-8) if necessary combine like terms
julia-pushkina [17]

Answer:

x² - 64

Step-by-step explanation:

Given

(x + 8)(x - 8)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 8) + 8(x - 8) ← distribute both parenthesis

= x² - 8x + 8x - 64 ← collect like terms

= x² - 64

Given the speeds of each runner below, determine who runs the fastest.
alexandr402 [8]

Answer:

Brooke

Step-by-step explanation:

We can solve this by figuring out how far each person runs a second

Stephanie runs 12 feet a second so nothing needs to be done here

Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet

Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75

Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18

Brooke obviously runs the furthest in one second and therefore she's the fastest runner

Question 1
Flauer [41]

Answer:

<em>Correct choice: b. $1221.00</em>

Step-by-step explanation:

<u>Compound Interest</u>

It occurs when the interest is reinvested on each compounding period. When it happens interest in the next period is then earned on the principal sum plus previously accumulated interest.

The formula is:

{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

The initial deposit on a savings account is P = $1000. The account provides an annual rate of r = 4% = 0.04 compounded monthly. The value of n is 12 since there are 12 months in a year. The money is left in the account for t=5 years. Substituting the values:

{\displaystyle A=\$1000\left(1+{\frac {0.04}{12}}\right)^{12*5}}

{\displaystyle A=\$1000\left(1.00333}\right)^{60}}

A = $1221

Correct choice: b. $1221.00
