(80pts) The ratio of the number of A's in the class to B's in the class was 2:5. How many people got A's if there were 40 people
allsm [11]

Make a proportion using the ratio (A:B) given and number of As and Bs really gotten in the class (\frac{A's}{B's})

\frac{2}{5} = \frac{A}{40}

Cross multiply

2 * 40 = 5 * A

80 = 5A

Isolate A by dividing 5 to both sides

80/5 = 5A/5

16 = A

If 40 people in the class got B's then 16 people got A's

Hope this helped!

The factor of the provided polynomial with the after the factorization process are similar to option A, which is

3xy(x^3y^2 - 5xy+ 2)

<h3>What is factor of polynomial?</h3>

The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.

The given polynomial equation in the problem is,

3x^4y^3 - 15x^2y^2+ 6xy

The above equation has the unknown variable x and y and the highest power of this unknown variable is 3.

Take out the highest common factor 3, which can divide each term of the above equation (3, 15, 6). Thus,

3(x^4y^3 - 5x^2y^2+ 2xy)

Take out the highest common factor in terms of variable, which can divide each term of the above equation. Thus,

3xy(x^3y^2 - 5xy+ 2)

Thus, the factor of the provided polynomial with the after the factorization process are similar to option A, which is

3xy(x^3y^2 - 5xy+ 2)

1. What is the value of x? Enter your answer in the box
diamong [38]

Answer:

X=5, X=9

Step-by-step explanation:

The first one has two sides that are equal length, so the angles opposite of those sides are equal. This means that there are 2 73 degree angles. A triangle only had 180 degrees, so the last angle is equal to 34 degrees. When you set 6x+4=34, x is equal to 5.

The second triangle is an equilateral triangle, so every angle is equal to 60 degrees. We can set 7x-3=60. Add 3 to isolate x. 7x=63. Divide by 7 to solve for x. x=9.
