Find Mack's debt-to-income ratio if his monthly expenses are $2850 and his monthly salary is $4000
PLS SHOW WORKKKK!!!
Will give brainillest to person that shows work :)
Answer:
debt-to-income ratio= 0.7125
Step-by-step explanation:
Giving the following information:
Monthly expenses= $2,850
Monthly income= $4,000
To calculate the debt-to-income ratio, we need to use the following formula:
debt-to-income ratio= monthly debt payment / gross monthly income
debt-to-income ratio= 2,850/4,000
debt-to-income ratio= 0.7125
As a percentage:
debt-to-income= 0.7125*100
debt-to-income= 71.25%
The debt-to-income ratio is the percentage of your income dedicated to paying your debts.

What is the volume of the cone?
A. 2876.7 yd
B. 4625.36 yd
C. 4258.44 yd
D. 2787 64 yd
Answer:
D. 2787.64 yd^3
Step-by-step explanation:
This is the formula for the volume of a cone:
[tex]V=\frac{1}{3} \pi r^2h[/tex]
The height of the cone is 22 yd. The radius of the base of the cone is not given but we can use the diameter to calculate it since the radius is equal to half of the diameter.
[tex]r=\frac{1}{2}d\\r=\frac{1}{2}(22)\\r=11yd[/tex]
Therefore, the radius of the base of the cone is 11 yd.
Now, we plug our values into the formula and solve.
[tex]V=\frac{1}{3} \pi r^2h\\V=\frac{1}{3} \pi (11^2)(22)\\V=\frac{1}{3} \pi (121)(22)\\V=\frac{1}{3} \pi (2662)\\V=\frac{1}{3} \pi (2662)\\V=2787.64 yd^3[/tex]
Therefore, the volume of the cone is equal to 2787.64 yd^3.

Ericka observed the total variation in the water level over 6.2 years to be −13.64 mm. She compared this to the average annual trend, which shows the water level rising 1.8 mm/year. Remember, she used 6.2 years as her time period. What is the difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
__________millimeters
Answer:
In the area that she observed, the water level fell 13.64mm over 6.4 years, for an average annual rate of change of: -13.64 ÷ 6.2 = -2.2 mm/ year.
f(x) = |2x + 1| + 3
g(x) = -2
find (f + g)(x)
A.(f + g)(x) = |2x + 2|
B.(f + g)(x) = |2x| + 2
C.(f + g)(x) = |2x + 1| + 1
D.(f + g)(x) = |2x + 4| - 2
Answer:
(f + g)(x) = I2x + 1I + 1 ⇒ C
Step-by-step explanation:
Let us solve the question
∵ f(x) = I2x + 1I + 3
∵ g(x) = -2
→ We need to find (f + g)(x), which means add the two functions
∵ (f + g)(x) = f(x) + g(x)
→ Substitute the right side of each function on the right side
∴ (f + g)(x) = I2x + 1I + 3 + (-2)
→ Remember (+)(-) = (-)
∴ (f + g)(x) = I2x + 1I + 3 - 2
→ Add the like terms in the right side
∵ (f + g)(x) = I2x + 1I + (3 - 2)
∴ (f + g)(x) = I2x + 1I + 1

Help please on circle theorems
Answer:
n = 28
Step-by-step explanation:
The angle at the centre is twice the angle on the circle subtended on the same arc, then
35 + m = 0.5 × 98 = 49 ( subtract 35 from both sides )
m = 14
∠ n is at the centre subtended on the same arc as ∠ m , thus
n = 2m = 2 × 14 = 28
Write a simplified expression that represents the perimeter of an irregular quadrilateral with some de lengths (2 1/4t - 5) (4t + 3) (1/2t - 1) (3t + 2)
Answer:
[tex]Perimeter = \frac{39t-4}{4}[/tex]
Step-by-step explanation:
Given
[tex]Lengths: (2\frac{1}{4}t - 5), (4t + 3), (1/2t - 1), (3t + 2)[/tex]
Required
Determine the perimeter
The perimeter is calculated as the sum of the lengths of the irregular shape.
i.e.
[tex]Perimeter = (2\frac{1}{4}t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)[/tex]
Remove brackets
[tex]Perimeter = 2\frac{1}{4}t - 5 + 4t + 3 + 1/2t - 1 + 3t + 2[/tex]
Collect Like Terms
[tex]Perimeter = 2\frac{1}{4}t +4t + 1/2t + 3t - 5 + 3 - 1 + 2[/tex]
[tex]Perimeter = 2\frac{1}{4}t +4t + 1/2t + 3t -1[/tex]
Convert mixed number to improper fraction.
[tex]Perimeter = \frac{9}{4}t +4t + 1/2t + 3t -1[/tex]
Take LCM
[tex]Perimeter = \frac{9t + 16t + 2t + 12t}{4} -1[/tex]
[tex]Perimeter = \frac{39t}{4} -1[/tex]
Take LCM
[tex]Perimeter = \frac{39t-4}{4}[/tex] --- The perimeter of the shape
We want to find the perimeter of the irregular quadrilateral given that we know its lengths. By direct computation, we will get:
P(t) = (39/4)*t - 1
Remember that for any figure, the perimeter is defined as the sum of the lengths of each side.
Here we have that the lengths of the four sides of the quadrilateral are:
(2 1/4t - 5)
(4t + 3)
(1/2t - 1)
(3t + 2)
So we must sum that, we will get:
P = (2 1/4t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)
Notice that in the first part we have a mixed number, we can rewrite it as:
2 + 1/4 = 8/4 + 1/4 = 9/4
Then the sum is:
P = ((9/4)t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)
Now we simplify this sum:
P = (9/4 + 4 + 1/2 + 3)*t + (-5 + 3 - 1 + 2)
P = (39/4)*t - 1
So the perimeter, as a function of t, is:
P(t) = (39/4)*t - 1

URGENT PLEASE HELP!!Which is an equation of the line that has a slope of 2 and passes through the point (3,1)?
A. y=2r +5
B. y = 2x + 1
C. y = 2x - 1
D. y = 2x - 5
Answer:
The equation of the line is y = 2x - 5 ⇒ D
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slopeb is the y-interceptNote: To prove that a line passes through a given point, substitute x in the equation of the line by the x-coordinate of the point and solve to find y, if y equals the y-coordinate of the point, then the line passes through it
∵ The slope of the line is 2
∵ The line passes through the point (3, 1)
→ Find at first which equation has slope 2, then check if the line passes
through the point or not using the note above
A.
∵ y = 2x + 5
→ By comparing it with the form of the equation above
∴ m = 2
∴ The line has the same slope
→ Substitute x by 3 to find y
∵ y = 2(3) + 5 = 6 + 5 = 11
∵ y-coordinate of the point = 1
∴ The line does not pass through the point
B.
∵ y = 2x + 1
→ By comparing it with the form of the equation above
∴ m = 2
∴ The line has the same slope
→ Substitute x by 3 to find y
∵ y = 2(3) + 1 = 6 + 1 = 7
∵ y-coordinate of the point = 1
∴ The line does not pass through the point
C.
∵ y = 2x - 1
→ By comparing it with the form of the equation above
∴ m = 2
∴ The line has the same slope
→ Substitute x by 3 to find y
∵ y = 2(3) - 1 = 6 - 1 = 5
∵ y-coordinate of the point = 1
∴ The line does not pass through the point
D.
∵ y = 2x - 5
→ By comparing it with the form of the equation above
∴ m = 2
∴ The line has the same slope
→ Substitute x by 3 to find y
∵ y = 2(3) - 5 = 6 - 5 = 1
∵ y-coordinate of the point = 1
∴ The line passes through the point
∴ The equation of the line is y = 2x - 5

2x2 - 7x+k=0 is x =-1. Find the value of k.
2
Answer:
this is the correct solution for your question
Answer:
The value of k is -4.
Step-by-step explanation:
In order to find the value of k, you have to substitite x = -1/2 into the equation :
[tex]2 {x}^{2} - 7x + k = 0[/tex]
[tex]let \: x = - \frac{1}{2} [/tex]
[tex]2 {( - \frac{1}{2} )}^{2} - 7( - \frac{1}{2} ) + k = 0[/tex]
[tex]2( \frac{1}{4} ) + \frac{7}{2} + k = 0[/tex]
[tex] \frac{1}{2} + \frac{7}{2} + k = 0[/tex]
[tex]4 + k = 0[/tex]
[tex]k = - 4[/tex]
Given an inequality, what strategies can we use to determine where the boundary line is? Explain your strategies in detail.
4x+3y≥12
Answer:
The strategy is to find the x and y intercept of the given equation
Step-by-step explanation:
4x+3y≥12
In order to determine where the boundary line, we need to first get the x and y-intercept of the inequality expression given;
x-intercept occurs at where y = 0
when y = 0
4x + 3(0)≥12
4x ≥12
x ≥12/4
x≥ 3
Also y intercept occurs at where x = 0
4x+3y≥12
4(0)+ 3y ≥12
3y≥12
y≥12/3
y≥4
Hence the intercept of the line is at (3, 4). A thick line will pass through this point and the upper part of the graph will be shaded. The strategy is to find the x and y intercept of the given equation

What is the solution set to log(x + 7) > log3x?
Answer: (-∞, 3.5)
Step-by-step explanation:
Here we can use the relation:
Exp( Log(X)) = X
Now, we start with the equation:
log(x + 7) > log(3x)
Now we can apply the exponential function to both sides of the inequality to get:
Exp(log(x + 7)) > Exp(log(3x))
x + 7 > 3x
7 > 3x - x
7 > 2x
7/2 > x
3.5 > x
Then the solutions will be all the values of x smaller than 3.5, this set can be written as:
