Answer:

800 minutes

Step-by-step explanation:

Make 2 expressions, one for Plan A, and one for Plan B

Plan A:

$9, and 0.17 per minute

9+0.17x

Plan B:

$25, and 0.15 per minute

25+0.15x

We want to find when they are the same, so we can set them equal to each other

9+0.17x=25+0.15x

Solve by isolating the variable, x

Subtract 9 from both sides

0.17x=16+0.15x

Subtract 0.15x from both sides

0.02x=16

Divide both sides by 0.02

x=800  

At 800 minutes they will cost the same

Answer:

A: 28

Explanation:

Vertical angles are congruent.

Answer:

The answer would be 28% because the angles are vertical, which also makes them congruent. Congruent angles have the same angle measure.

Answer:

The amount of payment that needs to be applied to the debt balance to bring the debt to limit ratio to 15% is $2,250

Step-by-step explanation:

Here we have the card limit as $3,000

The card debit to limit ratio should be kept below 15%

Therefore, card limit of $3,000 = 100%

The protect FICA score card debt to limit ratio required required is 15% that is;

Maximum appropriate card debt is 15% of Max allowable card debt

Maximum appropriate card debt  = 15% of $3,000 = $450.00

Current debt on card = $3,000

Payment to be applied to the balance to pay it down to 15% is given by

[tex]\$3,000 - \frac{15}{100} \times \$3000 = \$3,000 - \$450 = \$2550[/tex]

Therefore a $2,550 payment will be applied to the balance to pay it down to 15%.

Final answer:

To reduce your credit card debt to 15% of a $3,000 limit, you would need to make a payment of $2,550. This is calculated by determining 15% of the limit and subtracting it from the current balance to find the necessary payment amount.

Explanation:

Calculating Payment to Lower Credit Card Debt to Ratio

If your credit card has a limit of $3,000 and you wish to keep your credit card debt to limit ratio below 15%, first determine what 15% of your credit limit is. Calculate 15% of $3,000, which is $450. Since your current balance is the full limit of $3,000, subtract the target balance of $450 from $3,000. The result is the payment needed to reduce your debt to within the desired ratio.

$3,000 * 0.15 = $450 (15% of your credit limit)

$3,000 - $450 = $2,550

Therefore, a payment of $2,550 will bring your balance down to 15% of the credit limit. Managing your credit utilization is important not just for meeting the credit score components but also for maintaining good financial health.

Step-by-step explanation:

Answer:

[tex] \frac{15 }{4} \pi \:[/tex]

Step-by-step explanation:

Radius of circle (r) = 18/2 = 9 ft

Central angle = 180° - 30° = 150°

[tex]length \: of \: arc \\ = \frac{150 \degree}{360 \degree} \times 2\pi \: r \\ \\ = \frac{150 \degree}{360 \degree} \times 2 \times \pi \: \times 9\\ \\ = \frac{5 }{12 } \times 18 \times \pi \: \\ \\ = \frac{5 }{4} \times 3\times \pi \:\\ \\ = \frac{15 }{4} \pi \:[/tex]

The length of the darkened arc can be found using the formula s = Δθr, where s is the length of the arc, Δθ is the angle of rotation, and r is the radius of curvature.

The length of the darkened arc can be found by using the formula for arc length: s = Δθr, where s is the length of the arc, Δθ is the angle of rotation, and r is the radius of curvature. In this case, the angle of rotation is 2π radians (since it is a complete revolution) and the radius is given. So, substituting these values into the formula, we have s = 2πr.

Answer:The answer is 50

Step-by-step explanation:

The first step is to add up the numbers in order to get the outcome

5 red + 20 blue +25 green =5+20+25 =50

Step 2

Probability =no of events /no of outcome

We were asked to find the probability of red

Where red represent event

And the summation of red ,green and blue represents outcome .

So probability of red =5/50 = 1/10

Step 3

Recall in the question ,we were told that the card was selected 500 times ,so we multiply the probability of getting red by 500

1/10 *500 =50

Therefore the probability of drawing a red card from the special deck 500 times is 50 .

Answer:

4

Step-by-step explanation:

Symmetry is when you can flip the figure over a line and it will perfectly match the other side.

We see that if we draw a vertical line down the middle and a horizontal line across the middle, we get mirror images. So that's 2.

Then notice that we can draw two diagonals across the image, one from the upper left corner to the lower right corner and the other from the upper right corner to the lower left corner. That's another 2.

We try to find more, but try as we might, there are no others to be found.

Thus, there are 4 lines of symmetry.

Hope this helps!

Answer:

Cosine W = 0.32

Step-by-step explanation:

Adj/Hypo = 12/37 = 0.3243 = 0.32

Final answer:

The cosine of ∠W in triangle ΔVWX is found by dividing the length of the side adjacent to ∠W (XW) by the length of the hypotenuse (WV), resulting in cos(∠W) ≈ 0.32 to the nearest hundredth.

Explanation:

In triangle ΔVWX, where ∠X=90°, VX = 35, XW = 12, and WV = 37, we are asked to find the value of the cosine of ∠W to the nearest hundredth. Since ∠X is a right angle, this triangle is a right triangle, and we can use trigonometric ratios to find the cosine of ∠W. The cosine of an angle in a right triangle is equal to the adjacent side over the hypotenuse.

To find the cosine of ∠W, we look at the sides adjacent to ∠W, which are XW and WV. The length of XW is 12, and WV, being the hypotenuse, is 37. Therefore, to find cos(∠W), we calculate 12/37. Doing this calculation, we get cos(∠W) ≈ 0.32 to the nearest hundredth.

The cosine is a trigonometric function that relates the lengths of sides in a right triangle to the angles, and it is specifically the ratio of the length of the adjacent side to the length of the hypotenuse.

Answer:

0.1419 ( (if upper and lower cases are interchangeable)

0.348 ( if upper and lower cases are distinct letters)

Step-by-step explanation:

Each digit has 36 possible choices as 26+10

computer generates six characters

there are only 26 choices for letters only, (if we assume upper and lower cases are interchangeable)

For number of letters-only arrangements = [tex]26^{6}[/tex] = 308915776

For number of alphanumeric arrangements = [tex]36^{6}[/tex]= 2176782336

In order to find the probability of letters-only arrangements : [tex]\frac{308915776}{2176782336}[/tex]

=>0.1419

Now, in different scenario if upper and lower cases are not interchangeable.

We will have 26+26+10=62 alphanumeric choices, and 52 alphabetic choices

Therefore, probability of letters-only arrangements will be [tex]\frac{52^{6} }{62^{6} }[/tex]

=>0.348

Answer:

The probability of all letters arrangement if the upper cases and the lower cases of the English alphabet are interchangeable = 14.2%

The probability of all letters arrangement if the upper cases and the lower cases are not interchangeable = 34.8%

The slope value calculated by Jalen is not correct. Jalen has used the ordered pairs in the wrong order.

What is the point slope form of a line ?

Point slope form is used to represent a straight line using its slope and a point on the line.

It is given that Jalen is computing the slope of a line.

We know that the equation of a line in point slope form is given by :

(y - y1) = m (x - x1).

As per the computation done by Jalen ordered pairs are (-4, 0) and (2, 3).

For the line : (x , y) = (4 , 0)  and (x1 , y1) = (2 , 3).

So ,

Slope will be equal to :

m = (y - y1) / (x - x1)

m = (0 - 3) / (4 - 2)

m = -3 / 2

So , the slope calculated by Jalen is not correct as he has used the ordered pairs in the wrong order.

Therefore , the slope value calculated by Jalen is not correct. Jalen has used the ordered pairs in the wrong order.

The probability that Mildred will select a dime first and then a month penny is 1/24.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Total possibilities = 16

So, Probability of a dime of the first draw = 10/16 = 5/8

and, Probability of a penny on the second draw = 1/15

Thus, Probability of both = 5/8 x 1/15

                                         = 1/24

The probability that Mildred will select a dime first and then a penny is 1/24.

To calculate the probability that Mildred will select a dime first and then a penny from her bag of coins, we need to consider the following steps:

1. Probability of selecting a dime first:
- Mildred has a total of 10 dimes, 5 nickels, and 1 penny in the bag.
- The probability of selecting a dime on the first draw is the number of dimes divided by the total number of coins, which is 10 dimes out of 16 total coins.

2. Probability of selecting a penny next:
- After selecting a dime on the first draw, Mildred will have 9 dimes, 5 nickels, and 1 penny remaining in the bag.
- The probability of selecting a penny on the second draw is the number of pennies divided by the total number of remaining coins, which is 1 penny out of 15 remaining coins.

3. To find the overall probability, we multiply the individual probabilities:
- Probability = (Number of dimes / Total coins) * (Number of pennies / Remaining coins)
- Substituting the numbers, we get (10/16) * (1/15) = 1/24.

Therefore, the probability that Mildred will select a dime first and then a penny is 1/24.
