The measure of the angle BAC is 72degrees
We have given that the
angle B=108 degrees and angle C=60 degrees.
We have to determine angle A
In parallelogram
What is the sum of the two angles?The sum of the two angles is 180 degrees.
Therefore we get,
angle A+ angle B=180 degrees
angle B=108 degrees
angle A +108=180
angleA=180-108
angleA=72 degrees.
Therefore the measure of the angle A is 72degrees

A state offers specialty license plates that contain 2 letters followed by 3 numbers. License plates are assigned randomly. All license plates are equally likely. Find the number of possible license plates that can be issued using this system
I am pretty positive the answer is 17,576
LLNNN, we contain 676000 combinations available for license plates.
How to estimate the number of possible license plates?The number on license plates exists in the form LLNNN, where L denotes a letter and N denotes a number.
As L can be anything from A to Z, there exist 26 combinations for that and as repetition stands allowed, for second and third letters, we also contain 26 combinations available, and therefore 26 × 26 = 676 combinations for letters.
But numbers exist from 0 to 9 i.e. 10 combinations for each place and a total of 10 × 10 × 10 = 1000 combinations.
Therefore, LLNNN, we contain 676000 combinations available for license plates.

Answer:
38.4895
Step-by-step explanation:
area of circle = pi * r^2
3.142 * 7^2 = area of the whole circle
as we only have 1/4 of the circle we divide our area by 4
(3.142 *7^2) / 4 = 38.4895
Answer:
38.4895
Step-by-step explanation:
basically you are finding a quarter of the area of the circle. So the formula is 1/4πr^2
so that's 3.142×7^2 and then divided by 4.

One angle of a parallelogram measures 20 what are the measures of the other three angles in the parallelogram
Answer:
160°, 20° and 160°[tex] \: [/tex]
Step-by-step explanation:
Let us assume A, B, C and D are the four angles of the parallelogram. Where, ∠A = 20° and we have to find the measure of ∠B, ∠C and ∠D
So, If ∠A = 20°, then So, also ∠C = 20°.
[Opposite angles of a parallelogram are equal to each other]Therefore,
The measure of ∠C is 20°⠀
And, ∠A and ∠B are adjacent angles. We know,
Sum of two adjacent angles = 180°So,
⇒ ∠A + ∠B = 180°
⇒ 20° + ∠B = 180°
⇒ ∠B = 180° – 20°
⇒ ∠B = 160°
So,
The measure of ∠B = 160°⠀
So, If ∠B = 160°, then So, also ∠D = 160°.
[Opposite angles of a parallelogram are equal to each other]Therefore,
The measure of ∠D is 160°round answer to nearest hundreth

hi people! so, i have a math dyslexia, this means i have a really hard time not only understanding math, but keeping up with all the problems and new stuff, could someone just give me an explanation of what algebra is in a way that you would describe it to a 5 year old?
Answer:
Math with letters
Step-by-step explanation:
Algebra is just like normal math but instead of you knowing all the numbers there are some numbers you dont know and those are replaced with letters. letters are there to you can replace them with any number, or if given the right problem you might have to find out what number replaces the letter to give you the right answer. for example take 1+x=2 here x would be replaced with 1 to make this true. or take y=2-x+3 if you replace x with any number you want that changes the (y) value to give you anything you want. Also the letters can be any letter you want they dont mean anything just there as place holders for numbers.

If an investor has a $5,000 pretax return, the state tax rate is 4.5%, and the federal tax rate is 22.0%, what is the real investment value? $1,325 $3,675 $3,900 $4,775
Based on the given parameters, the real value of the investment is $3675
How to determine the value of the investment?From the question, the given parameters about the investment are:
Pretax return = $5,000
State tax rate = 4.5%
Federal tax rate = 22.0%
The real value of the investment is calculated using the following formula
Real investment value = Pretax return - [(Pretax return * State tax rate) * Pretax return * Federal tax rate)]
Substitute the given values in the above equation.
Real investment value = 5000 - [(5000 * 4.5%) + (5000 * 22.0%)]
Evaluate the products
Real investment value = 5000 - [225 + 1100]
Evaluate the sum in the above equation
Real investment value = 5000 - 1325
Evaluate the difference in the above equation
Real investment value = 3675
Hence, the real value of the investment is $3675

The table below shows the weights of Liam's pumpkin, l(w), and

Patricia's pumpkin grows at a weekly rate of approximately 52%.
Assume the pumpkins continue to grow at these rates through week 13.
When comparing the weights of both Liam's and Patricia's pumpkins
in week 10 and week 13, which statement is true?
(1) Liam's pumpkin will weigh more in week 10 and week 13.
3) Patricia's pumpkin will weigh more in week 10 and week 13.
(3) Liam's pumpkin will weigh more in week 10, and Patricia's
pumpkin will weigh more in week 13.
4) Patricia's pumpkin will weigh more in week 10, and Liam's

Liam's pumpkin will weigh more in week 10, and Patricia's pumpkin will weigh more in week 13. Then the correct option is C.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The table below shows the weights of Liam's pumpkin, l(w), and Patricia's pumpkin, p(w), over a four-week period which represents the number of weeks.
Liam's pumpkin grows at a constant rate.
Patricia's pumpkin grows at a weekly rate of approximately 52%.
Let x be the number of the week and y be the weight in pounds.
The equation of Liam's pumpkin will be
[tex]\rm y - 2.4 = \dfrac{5.5-2.4}{7-6} (x- 6)\\\\y - 2.4 = 3.1(x- 6)\\\\y = 3.1x - 16.2[/tex]
Then the weight of Liam's pumpkin after 10 weeks will be
y = 3.1 × 10 - 16.2
y = 31 - 16.2
y = 14.8
Then the weight of Liam's pumpkin after 10 weeks will be
y = 3.1 × 13 - 16.2
y = 40.3 - 16.2
y = 24.1
The equation of Patricia's pumpkin will be
[tex]\rm y = a\times (1.52)^{x}[/tex]
For x = 6 and y = 2.5
Then
[tex]\rm 2.5 = a \times 1.52^6\\\\a \ \ = 0.203[/tex]
We have
[tex]\rm y = 0.203 \times (1.52)^{x}[/tex]
Then the weight of Patricia's pumpkin after 10 weeks will be
[tex]\rm y = 0.203 \times (1.52)^{10}\\\\y = 13.36[/tex]
Then the weight of Patricia's pumpkin after 13 weeks will be
[tex]\rm y = 0.203 \times (1.52)^{13}\\\\y = 46.93[/tex]
