Answer:
The answer is that there are 2 green pins and 5 yellow pins remaining in the bag.
Step-by-step explanation:
There are 3 green pins in the bag at the start and Yaqub gives one to his sister, so there are 3 - 1 = <<3-1=2>>2 green pins remaining in the bag. The rest of the pins in the bag must be yellow, so there are 2 green and 7 - 2 = <<7-2=5>>5 yellow pins remaining in the bag.
Answer:2 green 5 yellow
Step-by-step explanation:
a local civic theatre has 22 seats in the first row and 21 rows in all. each successive row contains 3 additional seats. how many seats are in the civic theatre
Using the arithmetic progression, If a theatre has 30 rows of seats there are 22 seats in the first row,21 in the second row, 51 in the third row, then the total number of people that the theatre hold is 2400
The total number of rows = 51
Number of seats in the first row = 22
Number of seats in the second row = 21
Number of seats in the third row = 51
Common difference= Second term - first term
= 26-22
= 4
The given sequence is in arithmetic progression
Substitute the values in the equation
= 15[44+29×4]
= 15[44+116]
= 15×160
= 2400
Hence, using the arithmetic progression, if a theatre has 51 rows of seats and there are 22 seats in the first row,21 in the second row, 51 in the third row, then the total number of people that the theatre hold is 2400

What is the Pythagorean theorem? How do you use it to find the length of a missing side in a right triangle? Give an example and show your work.
The sum of squares of two sides of a triangle is equal to another side of a triangle is called the Pythagorean theorem.
It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
c^2=a^2+b^2--------(1)
Where a,b, and c are sides of a triangle.
To measure the length of the missing side in a right triangle using the Pythagorean theorem:
c^2=a^2+b^2
By using this formula we can find the length of a missing side.
To understand more we have to solve an example:
let A, B, and C are points of a triangle AB, BC, and CA are the sides of the triangle.
Consider BC=3cm CA=4cm AB=?
Use equation(1) to find the length of AB
AB^2=BC^2+CA^2
AB^2=3^2+4^2
AB^2=9+16=25
AB=5cm

Am I correct? Since the measure of the triangle is always 18. So, I added 117+ 33 which gave me 150. Next, I subtracted 150 from 150 from one side. Then, I subtracted 180 from 150 which gave me 33.
The measure of the angle ∠ACD will be 150°. Then the correct option is D.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The internal angles ∠A is 33° and ∠B is 117°.
Then the measure of the internal angle ∠C is given as,
∠A + ∠B + ∠C = 180°
33° + 117° + ∠C = 180°
∠C = 30°
The angle ∠C and angle ∠ACD are supplementary angles. Then we have
∠C + ∠ACD = 180°
30° + ∠ACD = 180°
∠ACD = 150°
The measure of the angle ∠ACD will be 150°. Then the correct option is D.

The password is composed of four digits, hence the total number of passwords possible is of:
N = 10 x 10 x 10 x 10 = 10,000.
Considering that Jess would like an even number, there are only five outcomes possible for the last digit (0, 2, 4, 6 or 8), hence the number of outcomes is of:

Tamba jut received a bonu which increaed hi dipoable income by $860. If Tamba' marginal propenity to conume (mpc) i 0. 75, hi conumption rie by _______
The formula for calculating the change in consumption is MPC x Change in Disposable Income.Thus, Tamba's change in consumption = 0.75 x $860 = $645
The marginal propensity to consume (MPC) is a measure of the proportion of an increase in disposable income that is spent on consumption. In Tamba's case, his MPC is 0.75, which means that for every $1 increase in his disposable income, he will spend 75 cents on consumption. The formula for calculating the change in consumption is MPC x Change in Disposable Income. Therefore, when Tamba's disposable income increased by $860, his consumption increased by 0.75 x $860 = $645.

A pair of positive integers a and b is such that their greatest common divisor is 5 and their least common multiple is 55. Find the smallest possible value of a+b.
Answer:
Step-by-step explanation:
The greatest common divisor of two integers a and b is a divisor common to both integers that is greater than any other common divisor. The least common multiple of two integers a and b is the smallest positive integer that is a multiple of both a and b.
To find the smallest possible value of a+b, we can start by trying to find the smallest possible values of a and b that satisfy the given conditions.
Since the greatest common divisor of a and b is 5, we know that both a and b must be divisible by 5. We can write a = 5x and b = 5y, where x and y are positive integers.
The least common multiple of a and b is 55, so we know that both a and b must be factors of 55. We can write 55 as the product of its prime factors: 55 = 5 * 11. Since a is divisible by 5, we know that a must be equal to 5 or 25. Similarly, since b is divisible by 5, we know that b must be equal to 5 or 25.
There are four possible pairs of values for a and b: (5,5), (5,25), (25,5), and (25,25). The smallest of these is (5,5), which gives us a+b = 5+5 = 10. Therefore, the smallest possible value of a+b is 10.
