Answer:

Answer: -30

Step-by-step explanation:

${(8 - 10)}^{2} - 30 \div 5 \times 6 + 2$

BODMAS

let's first solve the bracket:

$= {( - 2)}^{2} - 30 \div 5 \times 6 + 2 \\ = 4 - 30 \div 5 \times 6 + 2$

then let's divide:

$= 4 - (30 \div 5) \times 6 + 2 \\ = 4 - 6 \times 6 + 2$

then let's multiply:

$= 4 - (6 \times 6) + 2 \\ = 4 - 36 + 2$

simplify:

$= - 30$

PLEASE HELP ME I NEED TO DO THIS BEFORE I GO TO SLEEP AND I AM SOOO TIRED AND DO NOT UNDERSTAND HOW TO DO THIS.

nadya68 [22]

Ok so, here goes:
simple interest: r- rate, A- amount in the end, t- time, P- principal
r = (1/t)(A/P - 1)
Putting in our numbers
r = (1/4)((21236/5309) - 1) = 0.75
r = 0.75

Converting r decimal to R a percentage
R = 0.75 * 100 = 75%/year

The interest rate required to get a total amount, principal plus interest, of $21,236.00 from simple interest on a principal of $5,309.00 over 4 years is 75% per year.

What is the solution of the proportions 22/11 = r/13?

vagabundo [1.1K]

R=26, you can use cross multiplication to figure this proportion out. 22 times 13 is 286 and 11 times r is 11r , leaving you with 286=11r. you would then divide each side by 11 to isolating the variable giving you r=26.
