A baseball camp is held at a complex that has 6 baseball diamonds. The coaches would like each diamond to have the same number of campers. Use divisibility rules to determine whether this is possible if 152 kids show up for the camp.
Answer:
Using divisibility rules, it is impossible to have exactly the same number of kids in each of the diamonds
Step-by-step explanation:
Here, we want to use divisibility rule to check for the possibility of 152 kids showing for the kids
Since we need exactly equal number of kids in each of the diamonds, we are going to test the possibilities that we can share 152 to have the same number of campers in each of the diamond
Mathematically 152/6 = 25.3333
Since we have a remainder for the division, it is impossible to share the campers equally in the six diamonds if 152 kids show up for the camp

NEED HELP ASAP‼️‼️‼️‼️‼️ What is the slope of the line that passes through the points (-6, 1) and (3, 7)?
Answer:
c. 2/3
Step-by-step explanation:
To find the slope, you subtract y^1 from y^2 and divide it by x^2 - x^1
Our y^2 is 7 and our y^1 is 1.
7-1 = 6
Our x^2 is 3 and our x^1 is -6.
3 - (-6) = 3+ 6 = 9
so our slope is 6/9, reduced is 2/3
I hope this helped, please mark Brainliest, thank you!!

Isaiah is mowing lawns for a summer job for every mountain Charlie charges an initial fee of $10 plus $6 dollars for each additional hour
1. write an equation in slope intercept form
2. how much money does he make after working one job for four hours
Answer:
y = 6x + 10
Isaiah makes $34.00 after working for 4 hours.
Step-by-step explanation:
Slope intercept form is y=mx+b
In this situation the equation would look like so, x = amount of hours:
y = 6x + 10
To solve for how much Isaiah earns after 4 hours plug in 4 instead of x.
y = 6(4) + 10
y = 24 + 10
y = 34
Isaiah makes $34.00 after working for 4 hours.
Hope that helps and have a great day!
The angles of a triangle are in the ratio 1 : 4 : 5.
Work out the size of the smallest angle?
Answer:
18°
Step-by-step explanation:
sum the parts of the ratio, 1 + 4 + 5 = 10 parts
The sum of the 3 angles in a triangle = 180° , then
180° ÷ 10 = 18° ← value of 1 part of the ratio
Since 1 is the smallest part of the ratio it represents the smallest angle, thus
smallest angle = 18°
A store originally purchased a refrigerator at a cost of $650.20 and marked it up 50%. After a few weeks, however, the store discounted the refrigerator 70% in order to make room for new merchandise. What was the discounted price?
Answer:
Step-by-step explanation:
Step one:
the original price of refrigerator = $650.20
the markup/raise is 50%
the new price after the raise is
= 50/100*650.20
=0.5* 650.20
=325.1
The raise is by $325.1
The new price is $325.1+ $650.20=$975.3
Step two:
there was a discount of 70%
so =(70/100)*975.3
=0.7*975.3
=682.71
The discounted price is $682.71
The new price is 975.3-682.71
=$292.59
Ashley is making soup. She needs 148 ml of chicken broth for her soup to have flavor. How many ounces of chicken broth does Ashley need for her soup?
Answer: 5.00 ounces
Step-by-step explanation:
To solve the question, we need to know that:
1 ounce = 29.57353193 milliliter
Since Ashley needs 148 ml of chicken broth for her soup to have flavor. We need to convert it to ounce as follows
1 ounce = 29.57353193ml
= 148 ml/29.57353193 ml
= 5.00 ounces approximately
Answer: 5.00 Ounce

A truck driver travels from a distributor to a retailer every week. The driver records the
distance that he is from the retailer at different times during his trip. After several weeks
of collecting data, the driver creates a scatter plot of the data.
The best-fit line is Y=73.6 - 67.8x
where x is the number of hours spent driving and y is the distance, in miles, from the
retailer.
Complete question is;
A truck driver travels from a distributor to a retailer every week. The driver records the distance that he is from the retailer at different times during his trip. After several weeks of collecting data, the driver creates a scatter plot of the data. The best–fit line is y = 73.6 – 67.8x, where x is the number of hours spent driving and y is the distance, in miles, from the retailer.
Which of the following statements are true? Select all that apply.
The distance from the retailer increases with time.
The distance from the retailer decreases with time.
The distributor is 67.8 miles away from the retailer.
The distributor is 73.6 miles away from the retailer.
The truck is traveling at a rate of 67.8 miles per hour.
Answer:
B: The distance from the retailer decreases with time.
Step-by-step explanation:
Formula for best fit line is;
y = mx + b
Where;
m is slope
b is y-intercept
We are told that the best–fit line is y = 73.6 – 67.8x
This can be written as;
y = -67.8x + 73.6
This means the slope is negative and when x = 0, y = 73.6 which is the y-intercept.
We are told that x is the number of hours spent driving and y is the distance, in miles, from the retailer.
Since we have a negative slope, it means that y is decreasing with increasing values of x.
Thus, we can say that the distance from the retailer decreases with time.
Jamilia has a weather station in her backyard. She uses a rain gauge to track the total rainfall during two storms.
1: Jamilia graphs the function describing mondays rainfall. Is the graph linear or nonlinear? How do you know?
2: what is the real-world meaning of the slope of the graph?
3: Next, Jamilia graphs the function describing Thursday’s rainfall. Is this graph linear or nonlinear? How do you know?
4: What does the y-intercept of the graph or Monday’s storm mean? Does the y-intercept of the graph of Thursday’s storm have the same meaning?
Answer:
1. The graph is linear because the precipitation increases at a steady rate of 3 mm every 15 minutes, or 0.2 mm per minute.
2.The slope of a line tells us how something changes over time, if the slope is found, the rate of change can be found. In this case it is telling us how the rain increases over time.
3.The graph is nonlinear. Because the rainfall total does not change at a constant rate, the points do not form a line.
4.The y intercept means the total rain that was present at the start of her recording, this means there was no rain when she first started her experiment.
Step-by-step explanation:
A linear function is such that has a constant rate, while a nonlinear function does not have a constant rate.
1. Monday rainfall
From the table that represents Monday rainfall, we have the following observations
As the time increases, the precipitation increases at constant interval.Time increases constantly by 15 minutes, precipitation increases constantly by 3 mmThis means that, the graph is a linear graph.
2. The slope
The slope in this case, is the amount of precipitation in one minute
3. Thursday rainfallFrom the table that represents Thursday rainfall, we have the following observations
As the time increases, the precipitation increasesTime and precipitation do not increase constantlyThis means that, the graph is a nonlinear graph.
4. The y-intercept
This is the value of precipitation when the time is 0
From the table,
The precipitation at 0 minute is 0
Hence, the y-intercept, is 0
And yes, both graphs have the same y-intercept

Q1) f(x) = 2x^2 - 5x, g(x) 3x^2 find f(2)
Answer:
f(2)= -2
g(2)= 12
Step-by-step explanation:
To solve this we use the substitution method. Since f(2) is your variable, we will plug the x-value of 2 into each equation
f(2)= 2(2)^2-5(2)
f(2)=8-10
f(2)= -2
If the same variable is used for both equations then g(x) would be g(2) as well leaving you with
g(x) = 3x^2
g(2)= 3(2)^2
g(2)=12

Is the calculation for the question: Write an expression for the calculation. Double the number 6 and then subtract 36 divided by 12. Is the answer 6 x 2 - 36 ÷ 12?
Answer:
Yes
Step-by-step explanation:
Yes the answer is 6 x 2 - 36 ÷ 12 and it is correct. Although you could change this arithmetic expression by adding parenthesis to make it easier to read and know which operations come first, like so...
(6 x 2) - (36 ÷ 12)
This would make it easier to see that the 6x2 must be done first and then the 36/12 before doing the subtraction.
What should be the first step to solve the equation? 2x + 9(x – 1) = 8(2x + 2) – 5 Combine like terms on each side of the equation. Use the distributive property on each side of the equation. Use the subtraction property of equality to subtract 5 from each side of the equation. Use the addition property of equality to add 2x to each side of the equation.

Find the 54th term of the arithmetic sequence —2,-8,-14, ...
Answer:
-320
Step-by-step explanation:
You would first create an explicit formula for the provided sequence.
The basic explicit formula for arithmetic sequences is , [tex]a_{n} = d(n-1) + a_{1}[/tex]where an is the number of the term, d is the number you are adding or subtracting by, n the location of the term, and a1 is the first number.
We would then substitute the values given.
We are trying to solve the value of the 54th term. This makes n = 54. The first number of the sequence is -2, so a1 is -2. Finally, d is -6 because we are subtracting 6 to each number in the sequence.
Therefore, our resulting equation would be[tex]a_{n} =-6(54-1)-2[/tex] , which equals -320.
Answer:
-320.
Step-by-step explanation:
n54 = a1 + d(54 - 1)
Here a1 = -2 and d = -8 - (-2) = -6.
So 54th term = -2 + -6*53
= -320.
