Maggie Jay owns her own car. Her June monthly interest was $250. The rate is 13 1/2 percent. Jay's principal balance at the beginning of June is: (Use 360 days)
Answers
Answer:
the principal balance at the beginning of June is $22,222.22
Step-by-step explanation:
The computation of the principal balance at the beginning of June is shown below:
Principal balance = Interest paid ÷ (Interest Rate ÷ 12 Months)
= $250 ÷ (13.5% ÷ 12)
= $22,222.22
Hence, the principal balance at the beginning of June is $22,222.22
David drove 580 km on 7 hour journey. on the city roads he drove 60km/h and on the he drove 100km/h. How long did he drive at each rate?
Answers
Answer:
3 hours on the city roads and 4 hours on the other roads
Step-by-step explanation:
580 (total miles driven) - 400 (4 hours of driving 100km/h) = 180 (miles left)
180 (miles left to drive) / 60 (km/h) = 3 (hours driven at the speed of 60km/h)

Answers
Answer:
Step-by-step explanation:
1). System of equations is,
-2x - y = -22 -------(1)
4x - 8y = 4 -------(2)
By satisfying these equations with the given point (9, 4),
Equation (1)
-2(9) - 4 = -22
-18 - 4 = -22
-22 = -22
True.
Equation (2)
4(9) - 8(4) = 4
36 - 32 = 4
4 = 4
True.
Given point lies on both the equations.
Therefore, the given point is the solution of the system of equations.
2). 3x - 3y = 27 -----(1)
-2x + 9y = -11 ------(2)
Satisfy the equations with the given point (-10, -1)
Equation (1)
3(-10) - 3(-1) = 27
-30 + 3 = 27
-27 = 27
False.
Equation (2)
-2x + 9y = -11
-2(-10) + 9(-1) = -11
20 - 9 = -11
11 = -11
False.
Therefore, the given point is not the solution of the system of equations given.

Hello There!
So if you didn't know an exterior angle of a triangle is equal to the two opposite interior angles of a triangle
So basically
∠XYZ=∠WXY+∠XWY
so to find ∠XWY we subtract the value of ∠WXY (45) from the value of the exterior angle (115)
115-45=70 so ∠XWY=70
Answer:
?+45=115° sum of two interior angle of the triangle is equal to the exterior angle
<XWY=115-45=70

If I had 60 units needed and units per case was 14 how many cases and additional units I got
Answers
Answer:
4 with a remainder of 4
Step-by-step explanation:
60 divided by 14 is 4 with a remainder of 4
The additional number of units required is 10 units.
Given that:
Total number of units needed = 60 units
Total number of units per case = 14
How to find the total number of cases required for the given question?So, the total number of cases required=Number of units needed / number of units per case.
Number of cases required = 60/14 = 4.285 (this means that 5 cases are required as 4 cases won't be up to 60 units)
With 5 cases, we have exceeded the required units needed :
Additional units will be : (14×5) - 60
Additional units = 70 - 60 = 10 units
Therefore, the additional number of units required is 10 units.

(Round your answer to two decimal places.) s =
Answers
Answer:
a) x = 1.52
b) s = 1.16
Step-by-step explanation:
We have that:
5 students watched 0 movies.
9 students watched 1 movie.
5 students watched 2 movies.
5 students watched 3 movies.
1 student watched 4 movies.
(a) Find the sample mean x.
Sum divided by the number of students. So
[tex]x = \frac{5*0 + 9*1 + 5*2 + 5*3 + 1*4}{5 + 9 + 5 + 5 + 1} = \frac{38}{25} = 1.52[/tex]
(b) Find the approximate sample standard deviation, s.
Standard deviation of the sample.
Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So
[tex]s = \sqrt{\frac{5*(0-1.52)^2 + 9*(1-1.52)^2 + 5*(2-1.52)^2 + 5*(3-1.52)^2 + 1*(4-1.52)^2}{24}} = \sqrt{\frac{32.24}{24}} = 1.16[/tex]

Explanation:
y=2/3x+6 multiply both side by 3 to get rid of fraction

2x+18=3y
2x-3y= -18 multiply both side by -1

Step-by-step explanation:
Hello There!
Our objective for this problem is to isolate the variables
To do so we use inverse operations
x+4<6
subtract 4 from each side
4-4 cancels out
6-4=2
we're left with
x<2
Step-by-step explanation:
It is just like a normal x equation just with an inequality. So for now, just represent the < as and =
so we have x+4=6
subtract 4 from both sides
x+4-4=6-4
x=2
Now we insert the <
x<6
so all values for x are all less than 6

A. (0,-7)
B. No solution
C. (0,0)
B. Infinitely many solutions
Answers
Answer:
Step-by-step explanation:
Note that the two equations are equivalent.
2y = 14-2x can be rearranged to y = -x+7, which is the same as the second equation. What you're looking is one line on top of the other.
Every shared point is a solution. Since there are infinitely many points on a line, and these lines share every point, there are infinitely many solutions.
