Please I need help and the calculation of which contract is better.
The monthly contract I am considering costs $30 per month with 75 minutes of free calls and 100 free text messages. Additional calls cost 10¢ per minute and additional text messages 10¢ each. An alternative is ‘Pay as you go’ which has no monthly charge but all calls cost 30¢ per minute and texts cost 10¢ each. I typically make 100 minutes of calls and 60 text messages each month. Which would be the better contract for me and by how much?
Answer:
You should go with the 1st, because it's cheaper.
Step-by-step explanation:
1st plan:
30$ which include 75 mins of free calls and 100 free text messages
25 more mins * 10¢ /min(0.1$/min) = 2.5$
You will pay 32.5$
2nd plan:
(calls)100*0.3$=30$
(text messages)100 * 0.1$=10$
30+10 = 40$
select the construction that guaranties A is a reflection of point A across line BC
Answer:
I think it's Axial Symmetry.
Step-by-step explanation:
You draw a perpendicular line to the line BC through A.You get your compass and set it to the distance between the point A and the line BC. Using that distance on your compass, put the point of your compass on the point where the perpendicular line and BC intersect. Mark the distance on the perpendicular line. The reflection is the point you mark on the perpendicular line.

20. Line L has a y-intercept of 2 and contains the points (a, a) and (2a, 12). If a is a positive constant, what is the slope of line L?
Answer:
(12 - a)/aStep-by-step explanation:
Given
Line L withy-intercept = 3Points (a, a) and (2a, 12)The slope is
m = (y2 - y1)/(x2 - x1) = (12 - a)/(2a - a) = (12 - a)/a(63 POINTS) please answer because i really need help marking brainlest to whoever gets it correct and answers fast!!

• The price of her meal was
$15.55.
• The sales tax was 7% of the
price of the meal.
• The tip was 18% of both the
meal and the sales tax.
How much money did Rhonda
pay for the meal, including tax
and tip?
Answer:
$18.71
Step-by-step explanation:
7.\° Of 15.55=2.22
15.55+2.22=17.77
18.\° Of 17.77=0.94
17.77+0.94=18.71

Find one counterexample to show that the conjecture is false.
1 and 2 are supplementary, so one of the angles is acute.
Choose the best counterexample for the conjecture.
O A. mZ1 = 119° and mZ2 = 61°
O B. mZ1 = 39° and mZ2 = 51°
O C. mZ1 = 32º and mZ2 = 157°
O D. mZ1 = 90° and mZ2 = 90°
the variables x and y are related proportionally. when x = 8,y= 12. find y when x =56
Answer:
y = 84
Step-by-step explanation:
[tex]\frac{8}{12} = \frac{56}{y}[/tex]
Cross multiply.
8y = 672
Divide both sides by 8 to get y = 84.

3 kills in 8 minutes. If each player continues at the same rate, who will reach more kills in 40 minutes? How many kills will each player have? Explain you answer. *
Answer:
Benjiro will have more kills because 40 divided by 10 is 4 so 4 times 4 is 16 while 3 times 5 is 15

What is linear pair?Linear pairs of angles are created when two lines cross at a single point. Angles are said to as linear if they are contiguous to one another following the junction of two lines. If two angles are adjacent and their measurements add up to 180°, they are supplementary. As a result, a pair of linear angles always sums to 180°.
In a linear pair, the total of the two angles is always 180 degrees.Angles that are next to one another are called linear pairs, however not all adjacent angles are linear pairs.A common vertex and common arm are shared by a pair of linear angles.Given:
<1 = 5x-15
<2 = 90
<3 = 2x
Now, using Linear pair
5x - 15 + 90 + 2x= 180
7x + 75 = 180
7x = 180-75
7x= 105
x= 105/7
x= 15
Hence, the value of x is 15.

Question: After watching some fish 40 feet below the surface of the water, a scuba diver went up 15 feet to explore a coral reef. Use a number line to help you create an equation that shows the location of the coral reef in relation to the water surface.
Answer:
C. -40+15 = -25
Step-by-step explanation:
The diver went down 40 feet underneath the surface, so that would be -40. When the diver went up 15 feet, that would be adding -40 to 15. So, the diver would be going closer to the surface after coming up 15 feet. -40+15 = -25

What's the equation of a line that passes through (-4,-7) and (4,-1)
Answer:
y=-x+3
Answer:
y = 3/4x - 4
Step-by-step explanation:
Slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (-1 - (-7)) / (4 - (-4))
= 6 / 8
= 3/4
y-intercept:
y = mx + b
use the slope above and anyone of the given points to find b. Let's use (4, -1)
(-1) = 3/4(4) + b
-1 = 12/4 + b
- 1 = 3 + b
b = -4
Equation of a line:
y = mx + b
use the m and b from above to form the equation of a line.
y = 3/4x - 4

1) A soccer tournament has 4 teams, A, B, C and D. Each team will play the other 3 teams once. In each game the winning team earns 3 points, losing team 0 points and ties earn 1 point to each team. After these games are completed, the two teams with the most points will play in the championship. If teams earn the same number of points then the tie-breaker is whichever team scored more goals. Team C loses their first two games to A and B. Are they automatically eliminated or is there still a chance they could advance?

Can I please get help with this?
Answer:
first problem) he messed up at 4(1 + 5n), only multiplying the 1 by 4, instead of both the 1 and 5n,
work-
-8n + 4(1 + 5n) = -6n - 14
-8n + 4 + 20n = -6n -14
12n + 4 = -6n - 14
18n +4 = -14
18n = -18
n= -1
second problem) he messed up towards the end, where he put 3x = 3x, then x=0. in this case, x would equal x, so the answer is "infinitely many solutions"
all the other work is correct in that problem
third problem) on the right side of the equation, ( 4x+10+3x-6), when they were adding the like numbers, instead of subtracting 6 from 10, they added 6, giving them 16 instead of 4
correct work-
2x - 8 + 3x +2 = 4x +10 + 3x -6
5x - 6 = 7x + 4
-5x -5x
-6 = 2x +4
-4 -4
-10 = 2x
-5 = x
