Answer:
Each car magnet costs $4.95 and each pom-pom costs $0.425
The club spent $495 on 100 car magnets and $85 on 200 pom-poms.
Step-by-step explanation:
I guess that we have to calculate the price of pom-poms and how much money was spent purchasing car magnets and pom-poms.
x + y = 300
2x = y (now we replace y)
x + 2x = 300
3x = 300
x = 100
The club purchased 100 car magnets and 200 pom-poms.
To determine the price of each pom-pom:
($4.95 x 100) + 200P = $580
$495 + 200P = $580
200P = $85
P = $0.425
Answer: tan A=4/3
Step-by-step explanation:
Theo đề ta có: 5sinA=4 suy ra: sinA=4/5, mà ta đã biết là: sinA= cạnh đối/cạnh huyền, suy ra: cạnh đối của góc A =4, cạnh huyền =5
Áp dụng định lí py ta go ta đc:
5^2=4^2+x^2
=) x=3
Vậy cạnh kề của góc A=3
Mà tanA = cạnh đối/cạnh kề
Vậy giá trị của tanA=4/3

Answer:
124
Step-by-step explanation:
360 - (90+146) = 124
You can make an error by not adding a zero to it and you can be confused.
The fourth step is incorrect.
<h2>Polynomial</h2>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Given
x² + 4x -12 is a polynomial.
<h3>How to factorize the polynomial?</h3>
x² + 4x - 12
Step 1. x² + 6x - 2x -12
Step 2. (x² + 6x) - (2x + 12)
Step 3. x(x + 6) - 2 (x + 6)
Step 4. (x + 6)(x - 2)
Thus, in fourth step in place of (x + 2), (x - 2) is to be put.
Thus, The fourth step is incorrect.
