Answer:
17.5
Step-by-step explanation:
I beleive since we are connecting midpoints you divide each side by 2 and add them all up to get the perimeter of the smaller triangle made with the ratio of 1:2
The midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Given
If the midpoints of the sides of ∆EFG shown below were connected with line segments.
Then the sides of the triangle get half.
Then the perimeter will be of a new triangle will be
[tex]\rm Perimeter = \dfrac{8}{2} + \dfrac{15}{2} +\dfrac{12}{2}\\\\Perimeter = 17.5[/tex]
Thus, the midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.

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
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.

Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary.
∠P = 180° -∠R = 180° -68°
∠P = 112°
Answer:
112 degrees.

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.

rate?
HURRY HELP
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
