Question Help
Challenge A cell phone plan costs $26.90 per month for 400 minutes of talk time. It costs an additional
$0.05 per minute for each minute over 400 minutes. To get e-mail access, it costs 20% of the price for 41
minutes of talk time. Your bill, which includes e-mail, is the same each month for 7 months. The total cos
for all 7 months is $257.46. Write and solve an equation to find the number of minutes of talk time you us
each month.
Let m represent the number of minutes over 400 minutes each month. Which equation represents the
given situation?

Answer:

the answer for this problem is y= -2x-48

Step-by-step explanation:

4x+2y= -96

2y= -96-4x

y= -48-2x

y= -2x-48

Tina's salary increased upto 5 between 2001 and 2006.

Graph is the pictorial representation of a mathematical relation, function in Cartesian or other mathematical plane.

Here in the given problem there is one graph in Cartesian Plane.

The graph shows the change in hourly wage of Tina with respect to year.

According to the graph,

Tina's hourly wage in 2001 is 5.50; in 2002 is 6.50; in 2003 is 7.00; in 2004 is 7.75; in 2005 is 8.50 and in 2006 is 10.50; in 2007 is 11.50.

Then the change in hourly wage of Tina in between 2001 and 2006 is = 10.50 - 5.50 = 5

Hence the change in hourly wage of Tina in between 2001 and 2006 is 5.

Answer:

1 / 256

Step-by-step explanation:

Sample space Total sections of spinner = (A, B, C, D) = 4

P(spinner stops on A) = 1 /4

Second spin :

P(stops on B) = 1/4

Third spin :

P(stops on C) = 1/4

Fourth spin :

P(stops on D) = 1/4

Hence,

P(A then B then C then D)

1/4 * 1/4 * 1/4 * 1/4 = 1

Answer:

4 pounds

Step by Step Explaintion

The required Mary can buy 4 pounds of mixed nuts with her remaining budget.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
If Mary has a total of $12 to spend and she spends $2.50 on dried fruit, then she has $12 - $2.50 = $9.50 left to spend on mixed nuts.

If mixed nuts cost $2.50 per pound, then Mary can buy $9.50 / $2.50 per pound = 3.8 pounds of mixed nuts.

However, since Mary cannot buy a fraction of a pound, the actual amount of mixed nuts she can buy will be limited to the nearest whole number.

Therefore, Mary can buy 4 pounds of mixed nuts with her remaining budget.

Answer:

8π cm^2

Step-by-step explanation:

Here's your solution

=> Area of biggest circle = πr^2

=> Area = 16π cm^2

=> Area of small circle = 4π cm^2

=> there are two circles hence both area =

8π cm^2

=> now, Area of shaded region = 16π cm^2 - 8π cm^

=> Area = 8π cm^2

Answer:

x = 31

m<ABC = 113

Step-by-step explanation:

The angles are supplementary.

x + 82 + x + 36 = 180

2x + 118 = 180

2x = 62

x = 31

m<ABC = x + 82 = 31 + 82 = 113

Answer:

x = 31

m<ABC = 113

Answer:

D) 12 and 13

Step-by-step explanation:

BC x CE = AC x CD

5 x 12 = AC x CD

60 = AC x CD

A) 6 x 10 = 60, yes

B) 3 x 20 = 60, yes

C) 4 x 15 = 60, yes

D) 12 x 13 ≠ 60, so no

The values that are not possible lengths for segments AC and CD,

is 12  and 13

Option D is correct

when two chords intersects in a circle , then the product of the length of segments of the chords are equal

From the given circle , the product of the measure of the segments are equal

[tex]AC \cdot CD= BC \cdot CE[/tex]

In circle R, BC = 5 and CE = 12

Substitute the values inside the formula.

[tex]AC \cdot CD= BC \cdot CE\\AC \cdot CD= 5 \cdot 12\\AC \cdot CD= 60[/tex]

Now we look at the options and see which one gives the product 60

[tex]6 \cdot 10=60\\3 \cdot 20=60\\4 \cdot 15= 60\\12 \cdot 13= 156[/tex]

The values that are not possible lengths for segments AC and CD,

is 12  and 13 because the product is 156 not 60.

Answer:

Process of elimination

Step-by-step explanation:

If Olive wants to choose a friend while not playing favorites, while also not being random, she has to eliminate the ones she knows she will NOT take on the trip. She can choose this by selecting the one she knows that will be best on the trip with her, depending on the situation.

Or, if Olive only has one friend, then it wouldn't be surprising that she would take that one friend on the trip, since she has no one else to choose. This way, it is not playing favorites, nor is it random. Hope this helps you!

The measure of angle L from the given triangle KLM is 57°.

Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

The formula for sine rule is sinA/a=sinB/b=sinC/c. Where, A=angle A, a=length of side a, B=angle B, b=length of side b, C=angle C and c=length side c.

Given that, in ΔKLM, l = 570 cm, k = 490 cm and ∠K=46°.

By using sine rule in the triangle KLM, we get

sinL/l=sinK/k

sinL/570=sin46°/490

Here, sin46°=0.7193

sinL/570=0.7193/490

sinL/570=0.001467

sinL=0.8367

∠L=sin⁻¹(0.8367)

∠L=57°

Therefore, by using sine rule the measure of angle L is 57°.
