Answer:

The answer is 12 minutes.

Step-by-step explanation:

It is given that the cost of one minute is $0.18. Firstly, you have to substract the remaing credits from her original credits :

$30 - $27.84 = $2.16

We have found out that she uses $2.16 for her long distance call. Next, you have to divide 18 cents from the uses in order to find out how many minutes she use :

[tex]1 \: min = 0.18dollar[/tex]

[tex]x \: mins = 2.16dollars[/tex]

[tex]x = 2.16 \div 0.18[/tex]

Answer:

Cube root of 1446

Step-by-step explanation:

The formula for the volume of a sphere is [tex]\frac{4}{3} \pi r^3[/tex]. Therefore, if we divide 1928pi by 4/3pi and then take the cube root, you will find the radius. In this case, 1928pi/(4pi/3)=1446, meaning that the radius is the cube root of 1446. Hope this helps!

The formula for the volume of a sphere is 4/3 the product of π and the cube of the radius of the sphere.

Therefore, if we're working backwards, we can start by multiplying 1928 by 4/3.

1928 x (4/3) = 2570.66666667

From there, we can find the cube root to find our radius.

(cube root) of 2570.6666667 = 13.698781

Therefore, the radius of the circle is 13.698781, or about 13.7.

Hope this helps! :)

Answer:

Yes, the sides are in the ratio 2:5.

Step-by-step explanation:

All sides divided by each congruent side are = to .4 and 2/5 is = to 4/10

The sides of triangles are not proportional, thus the triangle is not similar triangle.

Triangle is "a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees".

If the ratio of the "sides of the triangles ΔABC and ΔDEF are equal then the triangles are similar triangles".

According to the question,

In ΔRST and ΔWXU are similar triangle if ∠R = ∠W; ∠S = ∠W; ∠T=∠U

then   [tex]\frac{RS}{WX} = \frac{ST}{XU}[/tex] .

In ΔRST, side RS is 3 centimeters, side ST is 6 centimeters, and side RT is 6.4 centimeters. In ΔWXU, Side WX is 16 centimeters, side XU is 7.5 centimeters, and side WU is 15 centimeters.

[tex]\frac{3}{16} = \frac{6}{7.5} = \frac{6.4}{15}[/tex]  

Hence, the sides are not proportional then the triangle is not similar triangle.

Answer:

x = 2

Step-by-step explanation:

The residual value represents the vertical distance between an actual data point and the predicted value on the line of best fit. To find the residual value when x = 2, we need to substitute x = 2 into the equation of the line of best fit and calculate the corresponding y-value.

The equation of the line of best fit is y = 0.5x + 1.

Substituting x = 2 into the equation, we get:

y = 0.5(2) + 1

y = 1 + 1

y = 2

So, when x = 2, the predicted y-value on the line of best fit is 2.

To find the residual value, we need to compare this predicted value with the actual data point. However, the given data points are not provided in the question, so we cannot calculate the exact residual value.

Therefore, without the actual data points, we cannot determine the specific residual value when x = 2.

Final answer:

To determine the residual value for x = 2, we need the actual y value from the data points. The residual is the difference between this actual y value and the predicted value from the line y = 0.5x + 1. Without the actual y value, the residual cannot be calculated.

Explanation:

The subject of this question is residual value in the context of linear regression, which is a part of high school Mathematics. The residual is the difference between the actual y value of a data point and the y value predicted by the line of best fit. When x = 2, we first calculate the predicted value using the equation y = 0.5x + 1, which gives us y = 2. To find the residual value, we need the actual y value from the given data points. If there is no actual y value given specifically for x = 2, we cannot calculate the residual value. Without that actual data point, we cannot compare it to the predicted value of 2. Please provide the actual y value for x = 2 to determine the residual.

Answer:

Step-by-step explanation:

Given a ramp with a one-meter distance from edge to edge and reaches a height of 0.643 meters, the equivalent set up will form a right angled triangle where the length of the ramp will be the hypotenuse of the triangle and its height will be the opposite side of the triangle facing the acute angle directly.

To get the value of the acute angle, we will use the trigonometry ratio known as SOH, CAH, TOA.

Given length of ramp = hypotenuse = 1m

Height =Opposite side = 0.643m

Using SOH;

sin[tex]\theta\\[/tex] = [tex]\frac{opp}{hyp}[/tex]

sin[tex]\theta[/tex] = 0.643/1

sin[tex]\theta[/tex] = 0.643

[tex]\theta[/tex] =sin⁻¹0.643

[tex]\theta[/tex] = 40°

The value of the acute angle is 40°

Final answer:

The probability that the first two names chosen will both be girls from a hat that contains the names of nine boys and six girls is 1/7.

Explanation:

The question involves determining the probability of selecting two girls' names from a hat that contains the names of nine boys and six girls. We are dealing with a situation of probability without replacement, which means that once a name is drawn, it is not put back into the hat.

To calculate the probability of the first name drawn being a girl, we have 6 girls out of the total 15 students, which gives us a probability of 6/15. If a girl's name is drawn first, there will then be 5 girls' names left and 14 names total. So, the probability of the second name drawn being a girl as well is then 5/14.

To find the overall probability of both events happening, we multiply the two probabilities together: (6/15)
x (5/14) = 30/210 = 1/7. Therefore, the probability that the first two names chosen will both be girls is 1/7.

Answer: There will be $2951.52 money in the account in 15 years

Step-by-step explanation:

Given: Principal ; P = $1200

Interest rate;r  = 6% compounded continuously

Time; t  = 15 years

As we know the compounded continuously formula is given by

[tex]A= Pe^{rt}[/tex] where A is amount , P is principal , r is rate, t is time and e be the mathematical constant.

So according to question we have

[tex]A= 1200 e^{0.06 \times 15} = 1200 e^{0.9} \approx 2951.52[/tex]

Hence, there will be $2951.52 money in the account in 15 years

The line segment from a vertex to the middle of the other side is what is meant by a median. When the vertex is an angle in an equilateral triangle or the non-congruent angle of an isosceles triangle, it is also an angle bisector.

Given:

From the figure CP = PB then AP is a median.

AP= 18 units

Now, the line QB divides the line AP in ratio 2:1.

So, KP = AP /3

Answer:

I think its 90 but im not sure.

Step-by-step explanation:

Final answer:

To find the total amount won by Pip and Sara, a ratio problem was solved by establishing an equation from the given ratio 7:3 and the fact that Pip gets £36 more than Sara, resulting in a total amount of £90.

Explanation:

The question involves solving a problem based on a ratio and determining the total amount of money shared by Pip and Sara. The ratio in which Pip and Sara share the money is 7:3, and since Pip gets £36 more than Sara, we can set up equations to find the individual and total amounts.

Let's denote Sara's share as S, hence Pip's share will be S + £36.

According to the ratio given, Pip's share to Sara's share is 7 to 3, so we can write the equation:

7S = 3(S + 36)

7S = 3S + 108

4S = 108

S = 27

So Pip's share is £27 + £36 = £63.

Adding both shares, the total amount is £63 + £27 = £90.

Therefore, Pip and Sara got £90 altogether.

Answer:

Ariana

Step-by-step explanation:

560 is 93.33 percent of 600 and 825 is 94.29 percent of 875.

The required, Imani has a larger percent increase in their rent.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
Imani’s rent increased from $560 per month to $600 per month.
percentage increase in Imani’s rent  = 600 - 560 / 560 × 100%
                                                        = 7.14%

Ariana's rent increased from $825 per month to $875 per month.
percentage increase in Ariana's rent  = 875 - 825 / 875 × 100%
                                                        = 5.71%

Thus, the required, Imani has a larger percent increase in their rent.
