neve has 12 full box of jars of slime and 7 lose jars of slime if neve has a total of 187 jars of slime which equation can be used to find the number of jars in each box
Solving a linear equation, we can see that each box has 15 jars.
Which equation can be used to find the number of jars in each box?
We know that Neve has 12 full boxes of jars of slime, and 7 jars of slime, then if each box has N jars, the total number of jars that Neve has is given by the linear equation:
12*N + 7
Now we know that Neve has 187 jars in total, then we can write:
12*N + 7 = 187
We want to find the value of N, which is the number of jars in each box, so we need to solve the linear equation:
12*N + 7 = 187
12*N = 187 - 7
12*N = 180
N = 180/12 = 15
We conclude that there are 15 jars in each full box.

joe bought a condo for $200,000. he put down 20%, which was $40,000. how much does he owe on the condo?
By taking the difference between the total cost of the condo and the amount that he already paid, we conclude that Joe owes a total of $160,000 for the condo.
How much does he owe on the condo?To find how much he owes on the condo, we need to find the difference between the total cost of the condo, which is $200,000, and the amount that he already paid, which is $40,000.
(Remember that difference means a subtraction)
It gives.
$200,000 - $40,000 = $160,000

(i got it graphed like what i have already but I don't know if its right even thought i gotten it)
Using the equation of the parabola, the inequality represented is:
y ≥ -(x + 2)² + 8.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
For this problem, the vertex is at (-2,8), hence:
h = -2, k = 8.
y = a(x + 2)² + 8.
The y-intercept is of (0,4), when when x = 0, y = 4, which we use to find a as follows:

X in an example of stochastic variable.
What is meant by stochastic variables?
Typically, a random (or stochastic) variable is defined as a variable that can assume more than one value due to chance.
The correct answers are: (a) stochastic variable: By stochastic variable we mean a variable (here X: the weight of students) whose values are subject to variation due to chance.
Here since X is the weight of the children sampled, hence X will vary along with change in the sampling units which gets selected by chance.
Hence X for a sample A and X value for a different sample B will be different. So the values of X vary due to chance ( chance takes part in the selecton of the sample). So X is a stochastic variable.

The area of a triangle is [tex]\frac{1}{2} (bh)[/tex].
The height is already given: 8
But we need to find the base and since the hypotenuse is given and it's a right triangle, we can use the pythagorean theorem. (Hypotenuse is longest, slanted side of a right triangle)
The pythagoren theorem is [tex]a^2+b^2=c^2[/tex] where a and b are the sides, and c is the hypotenuse.
Plugging in the given values => [tex]8^2+b^2=10^2[/tex]
We have to solve for b. So, squaring 8 and 10 we get [tex]64+b^2=100[/tex].
Next, subtract 64 from both sides to get b by itself: [tex]b^2=36[/tex]
Square root both sides to get [tex]b=6[/tex].
Now that we have our base we can plug it in to the area of triangle formula: [tex]1/2(6*8)[/tex].

Root 40 to the nearest 10
Root 40 to the nearest 10 is 6.3
The root of a number in math is a number that when multiplied by itself produces the original number. For example, the square root of 49 is 7 because 7×7=49.
Rounding off to the nearest 10 means that we wish to round off the last two digits of a number, that is up to the tens place of a number.
We have been given that 40 is the number whose root we have to round off so here are step-by-step instructions for how to get the square root of 40 to the nearest tenth:
Step 1: Calculate. We calculate the square root of 40 to be: √40 = 6.32455532033676.
Step 2: Reduce. 6.32.
Step 3: Round. Round 6.32 so you only have one digit after the decimal point to get the answer: 6.3.
So therefore the nearest 10 of root 40 is 6.3

answer as an equation and solve, please help!!
The equation which represents the given situation as described about snow depths in the task content is; 4 + 3x = 1 + 5x and the solution is; x = 1 and a half hours.
At what time will the snow fall of the towns in discuss have the same snow depth according to the given rates?It follows from the task content that the time at which the snowfall in the towns in discuss will be equal be determined.
According to.the word phrases given;
A town has accumulated 4 inches of snow and the snow depth is increasing by 3 inches every hour. Hence, we have;
4 + 3x.
Also, a nearby town has accumulated 1 inch and the depth is increasing by 5 inches every hour. Hence ,we have;
1 + 5x
Consequently, when the snowfalls are equal, we have;
4 + 3x = 1 + 5x
3 = 2x
x = 3/2.
x = 1 and a half hours.

a company's charge for electricity is ¢6.434 per kilowatt-hour. in addition, each monthly bill contains a customer charge of $7.81. if last year's bills ranged from a low of $51.74 to a high of $192.28, over what range did usage vary (in kilowatt-hours)? course hero
The range in which the usage vary is from 682.77 kilowatt-hours to 2867.11 kilowatt-hours.
Given the charge of electricity charge is 6.434 cents per kilowatt-hour.
Fixed customer charge = $7.81
Bill range = $51.74 to $192.28
Since every value is in $ , we will first convert cents to dollar
per kilowatt-hour charge will be $6.434/100 ( as $1 = 100 cents )
per kilowatt-hour charge = $ 0.06434 …(1)
Lets us first find the lower range of usage
Last year's lowest bill was $51.74 (including the customer charge)
So last year lowest bill = $51.74-$7.81 = $43.93 …(2)
We know that (per KWh charge)x(no. of KWh used)=Total bill. …(3)
Substituting the values from (1) & (2) we get
(0.06434)x(no. of KWh used)=$43.93
no. of KWh used=[tex]\frac{43.93}{0.06434} = 682.77 KWh[/tex]
Similarly we will solve for maximum KWh used
Lets us find the maximum range of usage
Last year's highest bill was $192.28 (including the customer charge)
So last year highest bill = $192.28-$7.81 = $184.47 …(4)
Substituting the value of (1) & (4) in (3) we get
(0.06434)x(no. of KWh used)=$184.47
no. of KWh used=[tex]\frac{184.47}{0.06434} =2867.11 KWh[/tex]
Therefore , the The range in which the usage vary is from 682.77 kilowatt-hours to 2867.11 kilowatt-hours.
