2. Solve For B.(a - 3)

Answers

Answer 1

Answer:

Step-by-step explanation:

Sum of angles inside triangle is 180

b + (a -3) + 90 =180

b + a - 3 + 90 = 180

b + a +  87 = 180

b + a +  87 -87 = 180-87

b + a  = 180-87

b + a  = 93

b = 93 -a

HURRY HELP

Answers

Answer:

2.2% per year

Step-by-step explanation:

Problem:

You deposit $500 into a bank account and received $55 simple interest after 5 years. What had been the interest rate?

Result:

The interest rate was 2.2% per year.

Explanation:

Find interest rate by using the formula I = P*i*t , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.  In this example I = $55, P = $500 and t = 5 years, so

i = 55/500*5

i=0.022 = 2.2% per year

round 2 da whole numba and den boom shakalaka B ) i got my question wrong so that i could put the right answer here. bye yall

The number of bacteria doubling every 28 hours will be 1145 after 13 hours.

What is the formula for exponential growth and exponential decaying function?

The formula for exponential growth is y = y₀.e^(kt).

The formula for exponential decay is y = y₀.e^(-kt).

In the case of doubling the growth of bacteria, we can use the formula,

[tex]y_f = y_0\times2^{\frac{t_r}{t}[/tex], where [tex]y_f[/tex] represents the final population, [tex]y_0[/tex] is the initial population, [tex]t_r[/tex] is the time we are required to determine, and [tex]t[/tex] represents the time rate growth.

Therefore from the given information, the number of bacteria after 13 hours will be,

[tex]y_f = 830\times2^{\frac{13}{28}[/tex].

[tex]y_f = 830\times1.38[/tex].

[tex]y_f = 1144.86[/tex] or 1145 bacterias.

Which of the answer choices describes Monica's budget?

Monica's Budget

Living Expenses Rent $200
Electric $45 Contingency $20
Transportation $78 Annual Expenses
Food $190 Car Insurance $945
Entertainment $30 Books $280

It is in deficit.

It is balanced.

It is in surplus.

HELP ASAP!!!!!!!!!!!!THIS IS QUESTION 43

Answers

Answer:

It is in deficit

Step-by-step explanation:

If you take her income (655) and subtract all of the expenses, including adding the annual expenses together and dividing them by 12 months, the result would be negative.

It is in deficit describes the Monica's budget.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

We can calculate Monica's total fixed expenses as:

Rent + Electric + Transportation + Food + Entertainment = $200 + $45 + $78 + $190 + $30 = $543

Her annual expenses are:

Car Insurance + Books = $945 + $280 = $1225

Adding her fixed and annual expenses gives:

$543 + $1225 = $1768

Since her income is only $655, her expenses exceed her income and she is operating at a deficit. Therefore, the answer is: It is in deficit.

Hence, It is in deficit describes the Monica's budget.
