A man owes $5000 on his credit card. The APR is 20%. If he doesn’t repay any of the debt, how much will he owe after 4 years.
11cm by 6 cm rectangle
Answer:
Question unclear.
If the question was about the perimeter of the rectangle, it is calculated as:
= (Length * 2) + (Height * 2)
= (11 * 2) + (6 * 2)
= 22 + 12
= 34 cm
If the question was bout Area, the area is:
= Length * width
= 11 * 6
= 66 cm²
6. What is the equation in slope-intercept form of the line that passes
through the points (-3,-1) and (2, 9)?
Answer:
y=2x+5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(9-(-1))/(2-(-3))
m=(9+1)/(2+3)
m=10/5
m=2
y-y1=m(x-x1)
y-(-1)=2(x-(-3))
y+1=2(x+3)
y=2x+6-1
y=2x+5

Find tan 30°
Answer:
[tex]tan(30) = \frac{A}{B}[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find tan(30)
Let the side opposite 30 degrees be A and the side adjacent 30 degrees be B
So [using tangent identity]:
[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
This gives:
[tex]tan(30) = \frac{A}{B}[/tex]
What is the upper quartile in the box plot?
Answer:
121
Step-by-step explanation:

In the diagram below, OP is circumscribed about quadrilateral ABCD. What is
the value of x?
A. 52
B. 50
C.90
D. 92
The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
What is quadrilateral?
It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.
We have:
In the diagram below, OP is circumscribed about quadrilateral ABCD.
In a quadrilateral, the sum of the opposite angles is equal to 180 degree
x + 20 + 110 = 180
x + 130 = 180
x = 50
Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

Which step explains how to find the value of a in 6a = 72?
a. add 6 to both sides
b. divide both sides by 6
c. multiply both sides by 6
d. subtract 6 from both sides
Answer:
b divide both sides by 6
Step-by-step explanation:
6a = 72 if you divided each side by 6 you will get
a = 12 which would bring you to the actual answer.

What is the area of 19 centimeters?
Let's break this up:
Radius: 19
Diameter: 38
Circumference: 119.4
So...
The area of a circle with radius 19 is 1134
A = πr2 = π(d
2
)2 A = C2
4π
π = 3.1415
A = area
C = circumference or perimeter
r = radius, d = diameter
SOLUTION STEPS:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·192 = 1134 square cm(*)
Area of a circle in terms of diameter:
Area = π·(d
2
)2 = 3.14·(38
2
)2 = 3.14·(19)2 = 1134 square cm(*)
Area of a circle in terms of circumference:
Area = C2
4π
= 119.42
4π
= 14256.36
(4·3.14)
= 14256.36
12.56
= 1134 square cm(*)
(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
Result in other units of area:
A circle of radius = 19 or diameter = 38 or circumference = 119.4 cm has an area of:
1.134 × 10-7 square kilometers (km²)
0.1134 square meters (m²)
1134 square centimeters (cm²)
1.134 × 105 square millimeters (mm²)
4.3784 × 10-8 square miles (mi²)
0.135625 square yards (yd²)
1.22063 square feet (ft²)
175.77 square inches (in²)
WHICH OF THE FOLLOWING RATIOS ARE PROPORTIONAL?

B) 12/5, 60/75
C) 2/9, 11/36
D) 5/12, 10/32
Which of the following is a solution of the system 2x + y = 9 and 3x + 5y = 19.
2x+y=9
3x+5y=19
I will do this problem in 2 ways. I.)Substitution II.)Elimination
Solution I.) Substitution
We can subtract 2x from both sides in the first equation.
y=9-2x
Now we can substitute the y in the second equation with 9-2x
3x+5(9-2x)=19
-7x+45=19
-7x=-26
x=26/7
y=9-2(26/7)=11/7
Solution II.)Elimination
We can multiply both side of first equation by 5 to get a 5y in both equations.
10x+5y=45
Now because both are positive 5y we just need to do simple subtraction of the 2 equation, each side respectively.
(10x+5y)-(3x+5y)=45-19
7x=26
x=26/7
2*26/7+y=9
y=11/7
Ultimately you get the same answer, both are viable methods, some problems are faster with one method but I recommend mastering both since they are very useful.

Answer:
∠BDC=43°
Step-by-step explanation:
Since ABCD is a rectangle, ∠ADC=90
∠ADC=∠BDC+∠ADB
90=(7x+1)+(9x-7)
90=16x-6
16x=96
x=6
∠BDC=7x+1

The perimeter of a rectangle is represented by 4x^2+5x-2. The perimeter of a smaller rectangle is represented by x^2+3x+5. Which polynomial expression represents how much larger the first rectangle is than the smaller rectangle ?
PLease help !!!!
a is correct
Step-by-step explanation:
Area of Bigger rectangle = 4x2 + 5x - 2
Area of Smaller rectangle = x2 + 3× + 5
diff. = ( 4x2 + 5x - 2) - (x2 + 3x - 5)
= 4x2 + 5x -2-x2 - 3x - 5
= 3x2 + 2x - 7
HELP ASAP! I’m very confused and need help! Thanks!
Answer:
Step-by-step explanation:
Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27. So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Sorry if this is hard to understand. Good luck! :)
