Answer:

Option A is correct.

Step-by-step explanation:

The credit limit is $6000

New balance after the transactions = $ 3604.50

Available credit on Nikki's card = credit limit - New balance after the transactions

Available credit on Nikki's card = $6000 - $ 3604.50

Available credit on Nikki's card = $ 2395.50

So, Option A is correct.

Answer:

5x + 6 : 2x² + 12x

Step-by-step explanation:

Width = 4x

Length = x + 6

Perimeter

= 2(4x + x + 6)

= 2(5x + 6)

Area

= 4x(x + 6)

Ratio of perimeter to area:

= 2(5x + 6) : 4x(x + 6)

= (5x + 6) : 2x(x + 6)

= 5x + 6 : 2x² + 12x

Answer:

(5x + 6) : (2x² + 12x)

Step-by-step explanation:

Perimeter = 2(length + width)

= 2[4x + x + 6]

= 2(5x + 6)

Area = length × width

4x × (x + 6)

4x(x + 6)

Perimeter : Area

2(5x + 6) : 4x(x + 6)

(5x + 6) : (2x² + 12x)

Answer:

5 weeks

Step-by-step explanation:

So if the plant is 13 inches tall in the beginning every week adds 2 inches.

0 weeks = 13 inch

1st week = 15 inch

2nd week = 17 inch

3rd week = 19 inch

4th week = 21 inch

5th week = 23 inch

So it would take 5 weeks to grow 23 inches

Answer:

5 weeks for the plant to be 23 inches long

Step-by-step explanation:

You could take the size the plant is supposed to be, which is 23 inches long then subtract how tall the plant is which is 13 inches long then divide by 2 because the plant grows 2 inches each week. Or you could use a chart to help you, until you get to 23 inches. please give me the brainliest answer?

1weeks= 13 inches + 2 inches = 15 inches

2weeks= 15 inches + 2 inches = 17 inches

3weeks= 17 inches + 2 inches = 19 inches

4weeks= 19 inches + 2 inches = 21 inches

5weeks= 21 inches + 2 inches = 23 inches

Answer:

Option D (APEX)

Step-by-step explanation:

L= Student has lice

NL= Student has no lice

PT=Test Shows positive

NT=Test Shows negative

P([tex]\frac{NT}{NL}[/tex]) =0.7708 (Probability that a student has no lice and the test shows negative)

P([tex]\frac{NT}{L}[/tex]) = 0.0108 ( Probability that a student has lice and the test shows negative)

Terms Of Percentages

0.98618219 × 100

=98.6

Therefore your answer is 98.6% (Option D)

APEX

The probability that the student doesn't have lice, given that the student tested negative is P ( A ) = 98.6 %

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability that the student doesn't have lice, given that the student tested negative be P ( A )

Now , the equation will be

The probability that a student has no lice and the test shows negative is given by P ( NL ) = 0.7708

The probability that a student has lice and the test shows negative is given by P ( L ) = 0.0108

And , The probability that the student doesn't have lice, given that the student tested negative P ( A ) = P ( NL ) / [ P ( NL ) + P ( L ) ]

On simplifying , we get

P ( A ) = P ( NL ) / [ P ( NL ) + P ( L ) ]

P ( A ) = ( 0.7708 ) / [ 0.7708 + 0.0108 ]

P ( A ) = 0.98618

P ( A ) = 98.6 %

Hence , the probability is 98.6 %

Step-by-step explanation:

Today's stock listing for Parchar Special Effects shown below.

52 wk high  =  160.44

52 wk low   =   81.91

Symbol        =  PCR

Div.              = 7.55

Close           =  114.36

Net change = -4.89

Based on this information today's close is $114.36 and Net change is -4.89. It means the value of yesterday was 4.89 more than today's close.

Therefore, yesterday's price = 114.36 + 4.89 = $119.25

Yesterday's price was $119.25.

Answer:

(C) [tex]110^{\circ}[/tex].

Step-by-step explanation:

Angles formed by drawing lines from the ends of the diameter of a circle to its circumference form a right angle, therefore

[tex]{\angle}FED=90^{\circ}[/tex].

Now, it is given from the figure that [tex]{\angle}FEP=35^{\circ}[/tex], therefore

[tex]{\angle}FED={\angle}FEP+{\angle}DEP[/tex]

[tex]90^{\circ}=35^{\circ}+{\angle}DEP[/tex]

[tex]{\angle}DEP=55^{\circ}[/tex]

Now, we know that The angle subtended at the center of a circle is double the size of the angle subtended at the edge from the same two points, therefore

[tex]{\angle}PCD=2{\angle}PED[/tex]

[tex]{\angle}PCD=2(55^{\circ})[/tex]

[tex]{\angle}PCD=110^{\circ}[/tex]

Thus, the measure of arc PD is [tex]110^{\circ}[/tex].

Hence, option (C) is correct.

The measure of arc PD is 110. So, The correct option is option C.

Angles formed by drawing lines from the ends of the diameter of a circle to its circumference form a right angle, therefore

90° = 135° + ∠DEP

∠DEP = 50°

Now, here is given,

∠FEP = 35°

∠FED = ∠FEP + ∠DEP....(1)

Plug the value of ∠FEP = 35° in equation (1),

∠FED = 90

90 = 35 + ∠DEP

∠DEP = 55

∠PCD = 2∠PED

∠PCD = 2 (55)

∠PCD = 110

Therefore, the measure of arc angle PCD is 110.

Answer:

30%

Step-by-step explanation:

1) Find the amount of time left to complete

60 minutes total - 42 minutes already played = 18 minutes left

2) Divide the amount of minutes left by the total minutes

18 minutes left ÷ 60 minutes total = 0.3

3) Multiply that value by 100 to turn the decimal into a percent

0.3 * 100 = 30%

Answer:

30%

Step-by-step explanation:

The answer is thirty percent. One way to solve this problem is to start by finding what percent of Vanessa’s practice time forty-two minutes represents.

Let p represent the unknown percent, and set up a proportion that compares the like ratios of parts to wholes.

Divide out the like minutes and cross multiply.

Divide both sides by sixty to solve for the percent of time Vanessa has already practiced.

Subtract seventy percent from one hundred percent to determine the percent of time she has left to practice.

Vanessa still has thirty percent of her practice time to complete.

When the input is -1, the output is 3

The answer is 3

In the given graph, the value of y at x = - 1 is 7.

This means that when the input x is - 1, the corresponding output y is 7. The graph visually represents the relationship between x and y, where each point on the graph corresponds to a specific x - y pair. When x takes the value - 1, the graph intersects the y-axis at the point (- 1, 7), indicating that the output y is 7.

In summary, for x = - 1, the associated output value y is 7, as shown by the graph's plotted point.
