Fred is looking over his credit card statement from the past couple of months there is a balance of 16443 this month which is 30% less than last month what was the balance last month
Answer:
Last month balance= $23.490
Step-by-step explanation:
Giving the following information:
Current balance= $16,443
Percentage decrease= 30%
To calculate the last's mont balance, we need to use the following formula:
Last month balance= current balance / (1 - percentage decrease)
Last month balance= 16,443/0.7
Last month balance= $23.490
In a right triangle, the hypotenuse has endpoints P(–3, 2) and Q(1, –3). On a coordinate plane, line P Q has points (negative 3, 2) and (1, negative 3). If R represents the third vertex in the triangle and R is located in the third quadrant, what is the length of PR?
Answer:
The length of PR is 5 units
Step-by-step explanation:
Here, we want to calculate the length of PR
Since PQ is the hypotenuse, it means that the right-angle would be between lines PR and RQ
Also, since R is on the third quadrant, then its coordinates are (-x,-y)
To get the coordinates of R since we know that we need a right angle, we drop a straight vertical line through P and a straight horizontal line through Q
What this mean is that the coordinates of R will take the x-coordinate of the point P and the y-coordinate of the point Q
Hence, we have that the coordinates of the point R is (-3,-3)
Now, we want to calculate the length of PR
PR will be the distance between the points P and R
Mathematically, to get this, we use the distance formula
That will be;
√(y2-y1)^2 + (x2-x1)^2
Thus, we have
√(2-(-3)^2 + (-3-(-3))^2
= √5^2 + 0^2
= √25 = 5 units
Answer:
The length of PR is 5 units.

What’s the equation gonna look like .
You will get marked as brainliest
The equation for the number x is seven more than one-fourth of itself is y = x/4 + 7.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The word expression is:
The number x is seven more than one-fourth of itself.
As we know,
The linear expression is defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.
If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.
x is any real number that is seven more than one-fourth of itself.
The equation will be:
y = x/4 + 7
Thus, the equation for the number x is seven more than one-fourth of itself is y = x/4 + 7.

Select all the following that make a right triangle:
Answer:
Please check the explanation.
Step-by-step explanation:
We know that for positive integers to be Pythagorean triples, they must have to work and satisfy the Pythagorean Theorem's formula:
a² + b² = c²
Here,
a and b are the sides or legs of a right triangle
c is the hypotenuse
Let us check now:
A) 3, 4, 5
a = 3, b = 4, c = 5
a² + b² = c²
3² + 4² = 5²
9 + 16 = 25
25 = 25
TRUE
Thus, we conclude that (3, 4, 5) makes a right triangle.
B) 8, 15, 17
a = 8, b = 15, c = 17
a² + b² = c²
8² + 15² = 17²
64 + 225 = 289
289 = 289
TRUE
Thus, we conclude that (8, 15, 17) makes a right triangle.
C) 6, 8, 10
a = 6, b = 8, c = 10
a² + b² = c²
6² + 8² = 10²
36 + 64 = 100
100 = 100
TRUE
Thus, we conclude that (6, 8, 10) makes a right triangle.
D) 5, 12, 13
a = 5, b = 12, c = 13
a² + b² = c²
5² + 12² = 13²
25 + 144 = 169
169 = 169
TRUE
Thus, we conclude that (5, 12, 13) makes a right triangle.
E) 7, 8, 9
a = 7, b = 8, c = 9
a² + b² = c²
7² + 8² = 9²
49 + 64 = 81
113 = 81
FALSE ∵ 113 ≠ 81
Thus, we conclude that (7, 8, 9) does not make a right triangle.
E) 7, 20, 21
a = 7, b = 20, c = 21
a² + b² = c²
7² + 20² = 21²
49 + 400 = 441
449 = 441
FALSE ∵ 449 ≠ 441
Thus, we conclude that (7, 20, 21) does not make a right triangle.
G) 10, 11, √221
a = 10, b = 11, c = √221
a² + b² = c²
10² + 11² = (√221)²
100 + 121 = 221
221 = 221
TRUE
Thus, we conclude that (10, 11, √221) makes a right triangle.
H) 5, 8, √80
a = 5, b = 8, c = √80
a² + b² = c²
5² + 8² = (√80)²
25 + 64 = 80
89 = 80
FALSE ∵ 89 ≠ 80
Thus, we conclude that (5, 8, √80) does not make a right triangle.

Answer:
44 km
Step-by-step explanation:
Let's find x using the Pythagorean theorem.
a^2 + b^2 = c^2
x^2 + 165^2 = 173^2
x^2 = 173^2 - 165^2
x^2 = 29,929 - 27,225
x = sqrt(2704)
x = 52

Tyler is making a wooden post that is 3.5 ft in length. He places marks 1 1/3 in apart from the post. After making 20 marks. Tyler says there is between 15 in. And 16 in. Of post that has not been marked.
Answer:
Yes, Tyler is right.
Step-by-step explanation:
Given that:
Length of wooden post = 3.5 feets
Position of tick mark = 1 1/3 inch apart
3.5 feets to inches
3.5 * 12 = 42 inches
Tick mark placed at 1 1/3 inch apart :
Number of tick parks made = 20
Total inches marked = (1 1/3 * 20) = (4/3 * 20) = 26.667 inches marked
Inches leg unmarked : 42 - 26.667 = 15.333333 inches
Hence, Tyler is correct.

Mailadai took a loan of Rs. 18000 from a bank at the rate of 6.6%. How much interest.he have to pay after 30 months?
Answer:
Rs. 2970 is the interest
Step-by-step explanation:
30 months is same as 30/12 = 2.5 months
I = PRT/100
P is 18000
R is 6.6%
T is 2.5 years
Substitute all these
I = (18,000 * 2.5 * 6.6)/100
= 2970

Solve by using elimination. Express your answer as an ordered pair.
Greetings again.
The answer is (3,5)
Explanation:
Other previous questions about the System of Two Variables Linear Equations. Previous questions, both y-terms have the same absolute-values but different operator/sign. Some questions previously have same operators as we multiply one of the equation by -1 to eliminate.
But this question, there are no terms that are same. Especially not the same looking value.
And what do we do if it's like this?
The answer is, do something to make both equations have same absolute value but different operators.
That is to multiply. For this question, I'll be eliminating x-term. So I'll multiply both equations to make the x-term have same absolute-value and different operator.
Because 2 and 3 can multiply into 6. Therefore, multiply the whole first equation by 3 and multiply the whole second equation by 2.
[tex]\left \{ {{2x+5y=31} \atop {3x-2y=-1}} \right. \\\left \{ {{2x(3)+5y(3)=31(3)} \atop {3x(2)-2y(2)=-1(2)}} \right. \\\left \{ {{6x+15y=93} \atop {6x-4y=-2}} \right.[/tex]
This is our new equations. Since we need to eliminate x-term. We multiply one of the equation by -1. I'll choose the second equation to multiply.
[tex]6x(-1)-4y(-1)=-2(-1)\\-6x+4y=2[/tex]
[tex]\left \{ {{6x+15y=93} \atop {-6x+4y=2}} \right.[/tex]
Then proceed with add/subtract vertically
6x-6x = 0
15y+4y = 19y
93+2 = 95
Therefore, we get 19y = 95
[tex]19y=95\\y=\frac{95}{19} \\y=5[/tex]
Our y-value is 5. However, we are not done yet. Since this is the System of Two Variables Linear Equation. We need to find the x-value too to express in ordered pairs. (x,y)
Choose any given equations to substitute y = 5 in. I'll substitute y = 5 in 3x-2y=-1
[tex]3x-2y=-1[/tex]
Substitute y = 5 in the equation.
[tex]3x-2(5)=-1\\3x-10=-1\\3x=-1+10\\3x=9\\x=3[/tex]
Thus, when y = 5, x = 3 or when x = 3, y = 5. As the ordered pairs = (x,y) Therefore, the answer is (3,5)
Answer:
(3, 5)
Step-by-step explanation:
Since none of the x y coeficcints are the same, we need to multiply entire equations
3(2x+5y=31)=6x+15y=93
2(3x-2y=-1)=6x-4y=-2
Now we have the same x coeficcionts!
(6x+15y=93)-(6x-4y=-2)=19y=95
we then divide 19 on both sides to get:
y=5
Now we know what y is, we'll need to plug 5 in for y in the second equation.
3x-2(5)=-1
3x-10=-1
3x=9
x=3
Isaac is starting a garden he has a space that is 8 feet wide by 7 1/2 feet long if he wants to put in a fence that goes around outside the garden how many inches of the fencing dose he need
Answer: 372 inches
Step-by-step explanation:
Given that :
Width = 8 feets
Length = 7 1/2 feets
The inches of fencing needed is obtained by calculating the perimeter of the garden :
Perimeter of rectangle (p) : 2(length + Width)
P = 2(7 1/2 + 8)
P = 2(15 1/2)
P = 31 feets
1 foot = 12 inches
31 feets = (12 * 31 ) = 372 inches
