Interest = $72.30
Principle = ?
Rate = 5%
Time = 3 years
Answer:
Step-by-step explanation:
Answer:
P = $ 482.00
Equation:
P = I / rt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
P = 72.3 / ( 0.05 × 3 ) = 482
P = $ 482.00
The principal required to
accumulate interest of $ 72.30
on a rate of 5% per year for 3 years is $ 482.00.
hope it helps :)

find the missing side of each right triangle. Round the answers to the nearest tenth
(this is trigonometry btw)
Answer:
1) cos(29) x 13 = 11.4
2) 18/sin(63) = 20.2
3) 14/tan(71) = 4.8
4) tan(18) x 11 = 3.6
5) 21/cos(35) = 25.6
6) tan(43) x 20 = 18.7
7) 9/sin(33) = 16.5
8) 17/tan(67) = 7.2
9) cos(38) x 19 = 14.97 or 15 (rounded to nearest 10th)
10) sin(59) x 26 = 22.3
Update: now all rounded to nearest 10th
Good Luck! x
please help me im so confused
Answer:
x = 27
Step-by-step explanation:
A circle adds up to 360 degrees. So we make this equation:
2x+21 + 5x+6 + 54 + 90 = 360
Combine like terms:
7x + 171 = 360
Subtract both sides by 171
7x = 189
Divide both sides by 7
x = 27
Answer:
Step-by-step explanation:
this has a bunch of "implied" things that you're supposed to know. one is that all the way around a circle is 360° two is that if you know the angle on the interior.. that is also the arc length.. so knowing those things we can say
360 = 54 + 2x + 21 + 5x + 6 + 90
put like terms together
360 = 171 + 7x
189 = 7x
27 = x
The angles of a triangle are in the ratio 1:2:3.What are the three angles of a triangle?
Answer:
30°, 60°, 90°
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 = 6 parts
divide the sum of the angles in a triangle. 180° by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
The 3 angles are 30°, 60° and 90°
Write a function that describes a relationship between two quantities. Two polynomial functions are given. d(x) = 2x3 - 2 +12 c(y) = 5y? - 9 Find 3d(x) • c(y) and write an equivalent expression.
The resulting equivalent expression is (6x^3 - 6x^2 +36)•(5y^2-9)
Polynomial functionsGiven the functions:
d(x) = 2x^3 - 2x^2 +12 c(y) = 5y^2 - 9
We are to find the expression 3d(x) • c(y)
3d(x) = 3(2x^3 - 2x^2 +12)
3d(x) = 6x^3 - 6x^2 +36
c(y) = 5y^2 - 9
Substitute into the expression:
3d(x) • c(y) = 6x^3 - 6x^2 +36(5y^2-9)
Hence the resulting equivalent expression is (6x^3 - 6x^2 +36)•(5y^2-9)

THIS IS WORTH 24 FREAKING POINTS SO GIVE ME NO WRONG ANSWER NOW, read the question carefully and answer it correctly and carefully
Answer:
I am not the best at math but I know that u can't change the bottom half of the fraction so it would just be four and then multiply the five and the three which would be fifteen. The answer would be 15/4ths. So you want to color in 15 boxes. Hopefully I could be of some kind of help to you!
Answer:
color in 15 boxes
15/32
Step-by-step explanation:
first off, the points are split so I'm only getting 12, just so that you know.
so 1/8x1/4 is 1/32, so each box is 1/32.
5/8x3/4=15/32 (multiply the top of the first with the top of the second and the bottom of the first with the bottom of the second)
so color in 15 boxes and the answer to the multiplication is 15/32

Error Analysis - Describe and correct the error a student made when multiplying two
binomials.
(2x + 2) (4x - 1)
8x ² - 2
Answer:
The correct answer is:
Error made: The student multiplied only corresponding terms in each bracket with each other
Correction: Each term in one bracket is to be multiplied with every term in the next bracket
Step-by-step explanation:
The student paired the terms in the brackets into like terms and multiplied the like terms like this:
(2x + 2) × (4x - 1)
collecting like terms: (2x, 4x) (2, -1)
(2x × 4x) (2 × (-1)) = 8x² - 2.
The above is the wrong way of expanding the bracket. The correct way of doing it is as follows:
(2x + 2) (4x - 1)
Each term in one bracket multiplies each term in the second bracket.
= 2x (4x - 1) + 2(4x -1)
= 8x² - 2x + 8x - 2
= 8x² + 6x - 2
The cost of making a shirt is half of what the shirt normally sells for. Today, the shirt is in a 15 percent discount from its normal price. What is the current price of the shirt?
Answer:
.85 times the cost to make the shirt
Step-by-step explanation:
Let x represent cost to make the shirt.
Today, the shirt is in a 15 percent discount from its normal price.
Discount = 15/100 * x = 0.15x
Current cost = Original cost - discount
Current cost = x - 0.15x = 0.85x
The answer is;
.85 times the cost to make the shirt

18a + 3 = 3 ( + )
Answer: 0
Step-by-step explanation: 18a + 3 = 3
-3 -3
--------------
18a = 0 you can't divide 18 and zero it would be 0
Answer:
So to factorize an expression, you put it into a form where if you expanded the brackets, you'd get the given expression.. if that makes sense. Therefore, you need to multiply the 3 by something to get 18a, and so the first term is 6a. You don't need to multiply 3 by anything to get 3, so the second term is 1. The final result looks like this :
3(6a + 1)

The area of this trapezium is 48cm2.
Work out .

X
Answer:
This is your answer ☺️☺️
Value of x is 19 cm.
What is area of trapezium?The area of a trapezium is defined as the number of unit squares that can fit into it . The area of a trapezium can be calculated using the lengths of two of its parallel sides and the distance (height) between them. The formula to calculate the area (A) of a trapezium using base and height is given as,
A = ½ (a + b) h where,
a and b = bases of trapezium, and,
h = height (the perpendicular distance between a and b)
Given
Area of trapezium = 48 [tex]cm^{2}[/tex]
Area of trapezium = [tex]\frac{(AB+DC).h}{2}[/tex]
48 = [tex]\frac{(AB+DC).h}{2}[/tex]
⇒ 48 = [tex]\frac{(5+x).(4)}{2}[/tex]
⇒ 96 = (5+x).4
⇒ 5 + x = [tex]\frac{96}{4}[/tex]
⇒ 5 + x = 24
⇒ x = 24 - 5
⇒ x = 19 cm
Hence, Value of x is 19 cm.
