If the arrow on spinner is spun once, then the probability that the arrow do not stop on number which is divisible by 3 is (c) 3/4.

We know that the spinner contains 8 numbers and each number is equally likely to be selected. Out of the 8 numbers, the numbers which are divisible by 3 are {3, 6}.

So, the numbers which are not-divisible by 3 are {1, 2, 4, 5, 7, 8},

We select one of the 6 numbers that are not divisible by 3 out of the total 8 numbers. so, the probability is :

⇒ Probability = (Number of favorable outcomes)/(Total number of outcomes),

⇒ Probability = 6/8,

⇒ Probability = 3/4,

Therefore, the correct option is (c).

Let x be the number of tickets sold.

Jaelyn's account balance after selling tickets: 150 + 58x

Erik's account balance after selling tickets: 480 + 6x

For both accounts to have the same amount, we set their balance equal to each other and solve for x:

150 + 58x = 480 + 6x

52x = 330

x = 330/52 = 6.25

So 6.25 tickets had to be sold before both accounts had the same amount of money.

You want to know the Social Security and Medicare taxes on an annual income of $122,300, given the respective tax rates are 6.2% and 1.45%.

The income is less than the Social Security maximum of 128,400, so the 6.2% tax applies to the full amount. Each tax amount is found by multiplying the income by the tax rate:

  SS: $122,300 × 0.062 = $7582.60 . . . . Social Security tax

  Med: $122,300 × 0.0145 = $1773.35 . . .Medicare tax

The values of 'x' and 'y' which make the quadrilateral PSZR a kite are

4 and 5 respectively.

A quadrilateral is a closed object in geometry that is created by connecting four points, any three of which are not collinear. There are 4 sides, 4 angles, and 4 vertices in a quadrilateral.

We know a kite is a special type of quadrilateral in which pair of adjacent sides are of equal length.

Therefore, PS = ZS and PR = ZR.

So, 5x - 4 = 3y + 1 and 8y - 4 = 36.

Now, 8y - 4 = 36.

8y = 40.

y = 5.

And hence, 5x - 4 = 3(5) + 1.

5x = 15 + 5.

5x = 20.

A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

First, multiply both the numerator and the denominator by 1000.

[tex]\frac{1.942}{9.43}[/tex] × 1000 = [tex]\frac{1942}{9430}[/tex]

Now, reduce the fraction to lowest terms. (Extract and cancel out 2.)

[tex]\frac{971}{4715}[/tex]

Convert to decimal.

[tex]\frac{971}{4715}[/tex] ≈ 0.205938494

Round to 4 decimal places.

Therefore, 1.942 ÷ 9.53 = 0.2060

Answer: Yes, I can solve this problem using a system of equations. Let n be the number of nickels and q be the number of quarters. Then we can write two equations:

The total number of coins is 25: n + q = 25.

The total value is $3.85: 0.05n + 0.25q = 3.85

We can solve this system of equations using substitution or elimination. Let's use substitution:

From equation (2), we can solve for n: n = (3.85 - 0.25q)/0.05.

Substitute this expression for n into equation (1): (3.85 - 0.25q)/0.05 + q = 25.

Multiply both sides by 0.05 to clear the denominators: 3.85 - 0.25q + 0.05q = 25 * 0.05.

Simplify the left side: 3.85 = 1.25q.

Divide both sides by 1.25 to solve for q: q = 3.08

Substitute this value for q into equation (1) or the expression for n from step (1) to find n: n = 25 - q = 25 - 3.08 = 21.92

Since n and q represent the number of coins, we round them down to the nearest whole number. So, there are 21 nickels and 3 quarters.

Step-by-step explanation:

The distance of barn B from the north end of pipe 27 is 258 ft to the nearest foot.

Let's call the distance from Barn B to the north end of pipe 2 as "d".

The distance from the barn to the south end of pipe 1 is 111 ft, the distance from there to the south end of pipe 2 is 23 ft, and the distance from the barn to the north end of pipe 1 is 127 ft.

So the total distance from barn B to the south end of pipe 2 is 111 + 23 = 134 ft.

Since the distance from barn B to the north end of pipe 1 is 127 ft, then the distance from the north end of pipe 1 to the north end of pipe 2 is d - 127 ft.

Since the distance from barn B to the south end of pipe 2 is 134 ft, then the distance from the south end of pipe 2 to the south end of pipe 1 is 134 - d ft.

Now, two right triangles with legs (d - 127) ft and (134 - d) ft.

By the Pythagorean Theorem, we have: (d - 127)² + (134 - d)² = 25²

Expanding and simplifying the equation gives us:

d² - 260d + 17296 = 625

d² - 260d + 16671 = 0

Using the quadratic formula:

d = (260 ± √(260² - 4 x 16671)) / 2

d = (260 ± √(677600 - 66768)) / 2

d = (260 ± √(61032)) / 2

d = (260 ± 246.9) / 2

d = 258 ± 123.5

So, the distance from barn B to the north end of pipe 2 is 258 ft or 381 ft.

Since the question asks to round the answer to the nearest foot, we can conclude that the answer is 258 ft.

The real interest rate is the interest rate that has been adjusted for inflation.

By reducing the principal by both the interest rate, by duration of time, and other factors, simple interest is derived. Simple return = principal plus interest plus hours is really the concept used in marketing. The easiest way to compute tax is by using this procedure. The most typical method of calculating income is as a portion of the outstanding sum. For illustration, if he borrows $100 from a buddy and pledges to pay back the loan at 5% interest, he will just pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you should pay interest, and you must collect interest when they lend it. Typically, interest is computed as a percentage of the loan total. The loan's interest is the name given to this percentage.

The interest rate charged on a loan expressed in dollars is called the nominal interest rate. The interest rate after accounting for inflation is known as the real interest rate. The nominal interest rate less the inflation rate equals the real interest rate.

the length of its hypotenuse will be 7√2 inches.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given, the two legs of an isosceles right triangle measure 7 inches

Since,

From the Pythagorean theorem:

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

So,

Hypotaneuse² = base² + height²

in our case,

Base = height = 7 inches

Hypotaneuse = √(7² + 7²)

Hypotaneuse = 7√2 inches

Therefore, the length of its hypotenuse will be 7√2 inches.
