What is 3t-12=60. Please explain
Answers
Answer:
24
Step-by-step explanation:
3t - 12 = 60
1. Add 12 to both sides
2. 60 +12=72
3. -12 + 12 = 0
4. 3t is left, so divide by 3 on both sides
5. 72 divided by 3 is 24
6. 3t divided by 3 is t
7. So t = 3

Next, they did a goods sale and earned 3/8 BINGO night and earned of their goal amount. How much more money does the Key Club still need to earn in order to reach their goal?
Answers
The amount of money more that Key Club still need to earn in order to have reached their target is $ 382. 50
How to find the money needed ?To find the amount of money needed by Kay Club to get to their target, first, find the amount of money earned from the bake sale :
= 2 / 5 x Target amount
= 2 / 5 x 1, 700
= $ 680
Then, they did a good sale and earned 3 / 8 of the amount :
= 3 / 8 x 1, 700
= $ 637. 50
The amount of money that Key Club still needs is:
= Total amount - amount raised
= 1, 700 - 680 - 637. 50
= $ 382. 50
In conclusion. Key Club would still need to engage in other activities to be able to reach their goal of $ 1, 700 as they have to raise $ 382. 50.

if you flip a coin four times, what is the probability of at least two consecutive heads
Answers
Probability of getting at least two consecutive heads is 8/16 or 50%.
Possibilities in flipping a coin for 4 times
S ={HHHH, HHHT, HHTH, HTHH,THHH, HHTT, TTHH, THTH, HTHT, HTTH, THHT, TTTH, TTHT, THTT, HTTT,TTTT}
The total number of possibilities is 16
Probability of getting at least two consecutive heads are
S= {HHHH, HHHT, HHTH, HTHH, THHH, HHTT, TTHH, THHT}
The total number of possibilities is 8
h = at least two consecutive heads
P(h) = P(2 consecutive heads appear) + (3 consecutive heads) + P(All heads)
P(h) = 5/16 + 2/16 + 1/16 = 8/16
P(h) = 8/16
Therefore the probability of getting at least two heads is 8/16.

the probability of getting at least two consecutive heads when flipping a coin four times is 3/4 or 75%.
To find the probability of at least two consecutive heads when flipping a coin four times, we can first calculate the total possible outcomes and then determine the favorable outcomes.
1. Total possible outcomes: Since each flip has 2 outcomes (heads or tails), for 4 flips, there are 2^4 = 16 total possible outcomes.
2. Determine favorable outcomes: We can first calculate the complement of the probability, meaning the probability of not getting two consecutive heads, and then subtract it from 1.
No consecutive heads outcomes:
1. Tails all 4 times: TTTT (1 outcome)
2. One head, three tails: HTTT, THTT, TTHT (3 outcomes)
Thus, there are 4 outcomes where there are no consecutive heads.
3. Calculate the probability of at least two consecutive heads: Since there are 16 total possible outcomes and 4 unfavorable outcomes, there are 16 - 4 = 12 favorable outcomes. The probability of at least two consecutive heads is the ratio of favorable outcomes to total possible outcomes, which is:
Probability = Favorable outcomes / Total possible outcomes = 12/16 = 3/4
So, the probability of getting at least two consecutive heads when flipping a coin four times is 3/4 or 75%.

Graph the inequality on the axes below. y≥3/2x-1
Answers
The graph will be a shaded region above and including the straight line y = (3/2)x-1.
We are asked to graph the inequality y ≥ (3/2)x-1. Describing the graph of an inequality, it will be a region on one side of a straight line.
So first we need to sketch the straight line, y = (3/2)x-1.
So find two points (x, y) satisfying this equation of line because a line need at least two points.
x y
0 -1
2/3 0
So first sketch a line joining the points (0, -1) and (2/3,0). This line will lie below the origin. That is, origin lies on the region above this line.
So the line y = (3/2)x-1 divided the plane into two regions, one of which represents the inequality y ≥ (3/2)x-1. So to find this required region we will check if origin lies in the region for inequality.
Substituting (0, 0) into y ≥ (3/2)x-1,
0 ≥ -1, which is true.
Thus in the graph, the region for inequality is the region where the origin lies. Hence shade the region above the line y = (3/2)x-1. This is the graph of the inequality y ≥ (3/2)x-1.

If your answer is a decimal, give it to 1 d. p.
Answers
It will take 5 minutes to print a batch of newspapers if 20 printers are used.
What is proportionality?
Proportionality is a mathematical relationship between two variables, where one variable is a constant multiple of the other. In other words, two quantities are proportional if they maintain a constant ratio to each other, meaning that as one quantity increases or decreases, the other quantity changes in the same proportion.
We are given that the time it takes to print a batch of newspapers, m, is inversely proportional to the number of printers used, n, and the equation of proportionality is:
m = k/n
where k is a constant of proportionality. We are also given that when k = 100, the equation is satisfied. So we can substitute k = 100 into the equation to get:
m = 100/n
To find the time it will take to print a batch of newspapers if 20 printers are used, we can substitute n = 20 into the equation:
m = 100/20 = 5
So it will take 5 minutes to print a batch of newspapers if 20 printers are used. Rounded to 1 decimal place, the answer is 5.0 minutes.

____ : referring to the fact that the distance between two or more points is equal.
Answers
The term that refers to the fact that the distance between two or more points is equal is "equidistant".
In geometry, the concept of equidistance is important when dealing with circles, which are sets of points that are equidistant from a single point called the center. This property is what allows circles to be defined in terms of their radius, which is the distance between the center and any point on the circle.
Equidistance is also important in other areas of mathematics and science. For example, in physics, equidistant points can be used to define a plane or surface that is perpendicular to a given line or axis. This is useful in many applications, such as designing electronic circuit boards or constructing buildings.
The concept of equidistance is not limited to mathematics and science, however. It can also be applied in everyday life. For instance, if you are planning a road trip and want to visit several destinations that are equidistant from your starting point, you can use this information to help plan your route and estimate your travel time.

At a particular restaurant, each chicken wing has 80 calories and each slider has 300 calories. A combination meal with sliders and chicken wings is shown to have 1360 total calories and twice as many sliders as there are chicken wings. Write a system of equations that could be used to determine the number of chicken wings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.
Answers
Answer:
let a = each chicken wing in a meal
let b= each slider in a meal
80a+300b=1360
b=2a
Step-by-step explanation:
80a+300b=1360 b=2a
The system of equations that could be used to determine the number of chicken wings(x) and the number of sliders(y) in the combination meal are; 80x + 300y = 1360 and y = 2x
Let each chicken wing be represented as x
Let each slider be represented as y
We are told that;
Number of calories for each chicken wing = 80 calories
Number of calories for each slider = 300 calories
A combination meal of both shows that there were 1360 calories.Thus;
80x + 300y = 1360 - - -(eq 1)
Also it shows that there are twice as many sliders as there are chicken wings.Thus;
y = 2x - - - (eq 2)

To complete a home repair a carpenter is renting a tool from the local hardware store. The expression 20x+60 represents the total charges, which includes a fixed rental fee and an hourly fee, where x is the hours of the rental. What does the first term of the expression represent?
Answers
The first term, 20x, captures the variable cost component of the rental charges and reflects the relationship between the number of hours rented (x) and the corresponding cost per hour (20).
The first term of the expression, 20x, represents the hourly fee charged by the hardware store for renting the tool.
In this context, the term "20x" indicates that the carpenter will be charged 20 for every hour (x) of tool usage.
The coefficient "20" represents the cost per hour, while the variable "x" represents the number of hours the tool is rented.
For example, if the carpenter rents the tool for 3 hours, the expression 20x would be
\(20(3) = 60.\)
This means that the carpenter would be charged 20 for each of the 3 hours, resulting in a total charge of $60 for the rental.
