Answer:

$ 0.30

Step-by-step explanation:

Given:

Average daily balance = $20

Daily period rate = 0.05%

Number of days in a cycle = 30 days

The formula to calculate the monthly Finance Charge is:

Monthly finance charge = Balance x APR x (Number of days)/365

We are given the Daily period Rate which is calculated as:

Daily period rate = APR/365

Therefore, we can write the above equation as:

Monthly finance charge = Balance x Daily Periodic Rate x Number of days

Using the given values, we get:

Monthly finance charge = 20 x 0.0005 x 30 = $ 0.30

Therefore, the monthly finance charge would be $ 0.30

Answer:

The answer is $0.30 or 30 cents

Step-by-step explanation:

From the question Given, we recall the following statement

The monthly finance charge if the average daily balance =$20

The daily periodic rate is =0.05%

The number of days in the cycle is =30

We solve for the monthly finance charge

We apply  the monthly Finance Charge formula:

Monthly finance charge = Balance x APR x (Number of days)/365

Thus,

20 x  0.05% = 0.01

0.01 x 30 days = 0.30  

Therefore the monthly finance charge is = $0.30 or 30cents or 30¢

Answer: (4.5, 6.5) is your solution

Step-by-step explanation:

You need either the x term or the y term to be the same in both equations so you can eliminate them...

8x=2y+5

6x=2y+14

Now you can subtract the two equations...

2x=9

Divide 9 by 2....

x=4.5 or 4 1/2

Plug in x into one of the original equations to find y...

13.5=y+7

Subtract 7 from 13.5...

6.5=y

Answer:

z = [tex]\frac{y-x}{3y-x}[/tex]

Step-by-step explanation:

2x+6yz=2xz+2y  (rearrange so that z is on one side)

6yz - 2xz = 2y - 2x   (divide both sides by 2)

3yz - xz = y - x   (factor our z from LHS)

z (3y - x) = y - x

z = [tex]\frac{y-x}{3y-x}[/tex]

Answer:

Add the two equations together to eliminate y

Step-by-step explanation:

X+y=3

4x-y=7

I would use elimination since one equation has +y and one equation has -y

Add the two equations together

X+y=3

4x-y=7

The greatest possible error for a measurement of 10 1/8 oz is ± 1/16 oz, considering that 1/8 oz is the smallest visible increment on the measuring scale.

The greatest possible error in a measurement refers to the smallest unit that the measuring instrument can discern. In the case of the measurement 10 1/8 oz, we consider the precision of the measuring tool used.

If the smallest division the scale can measure to is 1/8 oz, then the greatest possible error in this case would be ± 1/16 oz. This is because 1/8 oz is the smallest increment visible on the scale, and the actual measurement could be halfway between two increments.

The concept of greatest possible error is critical in determining the accuracy and precision of a measurement. It helps to understand how reliable a given measurement is.

For example, when taking several measurements of the same quantity, like the weight of grocery items, there is often a small variation. This variation is a normal part of measuring and can be due to the limitations of the measuring tool or the person taking the measurement.

Final answer:

The greatest possible error for the measurement of 10 1/8 oz is +/- 1/16 oz, which accounts for the uncertainty of the least precise digit in the measurement.

Explanation:

When considering the greatest possible error for a measurement, it's important to understand that this refers to the uncertainty associated with the least precise digit of the measurement. For a measurement like 10 1/8 ounces, if we are using a standard measuring device that has graduations for every 1/8 of an ounce, then the greatest possible error is half of the smallest unit measured, which in this case is 1/16 of an ounce.

The reason for this is because when a measurement falls between two lines or markings, the measurer must estimate the value to the nearest possible marking. If the measurement is exactly on a line, or marking, there is no need to estimate, but if it is not, then the convention is to record the number to the nearest marking and recognize that there's a potential error up to half the distance to the next marking. So, for the given measurement of 10 1/8 ounces, the greatest possible error would be +/- 1/16 of an ounce.

Answer:

9 hr

Step-by-step explanation:

vary directly means you should think about a constant being multiply to one variable to get another variable.

So we have E=kH

where E=earnings and H=hours and k is the constant of proportionality

So they give us when H=7 we have E=77 giving us 77=k(7) which means the constant of proportionality is 11

So that means no matter what the E and H are k is 11

So we have the equation is E=11H

Replace E with 99 and solve for H

99=11(H)

So H=9

Final answer:

Kevin can safely take sacks weighing up to 308.33 pounds each in the elevator, provided he takes six sacks at a time and the elevator's capacity is 2,000 pounds with Kevin weighing 150 pounds.

Explanation:

The student's question is asking for the maximum weight of each sack of grain that Kevin can deliver on the elevator, given the elevator's weight capacity and the additional weight of Kevin himself. To answer this question, we need to consider the weight that the elevator can hold minus Kevin's weight, and then determine how much weight is left for the sacks of grain.

The elevator has a capacity of 2,000 pounds, and Kevin weighs 150 pounds. This means the total weight that the elevator can carry in addition to Kevin is:

2000 pounds (elevator capacity) - 150 pounds (Kevin's weight) = 1850 pounds (available for sacks)

If Kevin needs to deliver six sacks at a time, we can divide the total available weight by six to find the maximum weight for each sack:

1850 pounds / 6 sacks = approximately 308.33 pounds per sack

Therefore, the weight of each sack must be 308.33 pounds or less for Kevin to safely use the elevator without exceeding its capacity.

Answer:

20

Step-by-step explanation:

100% - 20% = 80%.

80% of 25 = 25 x 0.8 = 20

When the number 25 is decreased by 20%, the result is 20.

To find the result when the number $25 is decreased by 20%, we need to calculate 20% of 25 and subtract that from 25.

20% of 25 is (20/100) x 25 = 5.

Subtracting 5 from 25, we get the result as 20.

Answer:

-2 + i

Step-by-step explanation:

v = -3i

w = 2 - 4i

v - w =

= -3i - (2 - 4i)

= -3i - 2 + 4i

= -2 + i

The given value of  v = -3i and w = 2-4i, so v-w = -2 + i.

Given: v = -3i, w = 2-4i

To find: v - w

Solution:

Substitute the values of v and w into the expression v - w.

v - w = -3i - (2-4i)

v - w = -3i - 2 + 4i

v - w = -2 + i

Answer:

C) A number line with an open circle on −8, shading to the left, and a closed circle on 9, shading to the right

Step-by-step explanation:

Given compound inequality,

x − 3 < −11 or x + 5 greater than or equal to 14.

⇒ x − 3 < −11 or x + 5 ≥ 14.

⇒ x < - 11 + 3 or x ≥ 14 - 5

⇒ x < -8 or x ≥ 9

Thus, the possible values of x are all real numbers less than -8 excluding -8 and all real numbers greater than 9 including 9,

That is, x ∈ (-∞, -8 ) ∪ [ 9, ∞ )

In the number line the numbers are arranged in ascending order from left to right also in the interval the excluded number is represented by open circle and included number is represented by closed circle.

Hence, correct option is,

Explanation:

There are 6 red marbles out of 10+6+3 = 19 total. So 6/19 is the probability of picking one red marble. If that marble is not replaced, then we have 6-1 = 5 red marbles left out of 19-1 = 18 total. The probability of picking another red is 5/18

We have 6/19 as the probability of picking red the first time, then 5/18 as the probability of picking another red marble. The first marble is not put back, and that marble is not replaced.

--------------------------

In terms of math notation, we can say

A = event of picking red on the first selection

B = event of picking red on the second selection

P(A) = 6/19

P(B|A) = 5/18

P(A and B) = P(A)*P(B|A)

P(A and B) = 6/19 * 5/18

The area watered by the sprinkler is 1117.0 sq. feet. The sprinkler sprays in a circular direction with an angle of 80° and a radius of 40 feet.

Option B

Step-by-step explanation:

step 1

Find the measure of angle A

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

∠A+∠B+∠C=180°

substitute the given values

∠A+23.4°+90°=180°

∠A+23.4°+90°=180°-113.4°=66.6°

step 2

Find the length of side BC (a)

Applying the law of sines

c/sin(C)=a/sin(A)

3.3/sin(90)=a/sin(66.6)

a=3.3*sin(66.6)/sin(90)

a=3.0 mm

step 3

Find the length side AC (b)

Applying the law of sines

c/sin(C)=b/sin(B)
