(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!

Help please If f(x) = -3x - 5 and g(x) = 4x-2, find (1-9)(x).

Mandarinka [93]

Answer:

-7x -3

Step-by-step explanation:

(f -g)(x) = f(x) -g(x) = (-3x -5) -(4x -2)

(f -g)(x) = -3x -5 -4x +2 = (-3-4)x +(-5+2)

(f -g)(x) = -7x -3

Select the correct answer. which expression is equivalent to the given expression? assume the denominator does not equal zero. a

Alexxandr [17]

If the denominator does not equal 0, the equivalent expression of $\frac{14x^4y^6}{7x^8y^2}$ is $\frac{2y^{4}}{x^{4}}$ $\frac{x^{10} y^{14}}{729}$

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

$\frac{14x^4y^6}{7x^8y^2}$

Divide 14 by 7

$\frac{14x^4y^6}{7x^8y^2} = \frac{2x^4y^6}{x^8y^2}$

Apply the law of indices

$\frac{14x^4y^6}{7x^8y^2} = \frac{2y^{6-2}}{x^{8-4}}$

Evaluate the differences in the exponents

$\frac{14x^4y^6}{7x^8y^2} = \frac{2y^{4}}{x^{4}}$

Hence, the equivalent expression of $\frac{14x^4y^6}{7x^8y^2}$ is $\frac{2y^{4}}{x^{4}}$

Convert the following radian angle 3.5 into degrees. Round decimal answers to nearest tenth. Use 3.14 for pi.

8_murik_8 [283]

Answer:

200.6°

Step-by-step explanation:

There are 180° in π radians, so the conversion is ...

(3.5 radians)×(180°/(π radians)) = (3.5×180/3.14)° ≈ 200.6°
