Answer:

C. $\frac{4}{10}$ and $\frac{10}{25}$

Step-by-step explanation:

The proportion between these fractions is true. Multiply 4/10 (numerator and denominator) by 2.5 to get 10/25. This is the only correct option.

Hope it helps!

Help me find answer to this

Debora [2.8K]

Answer:

$\angle B=41.81^\circ$

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

$\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}$

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

$\displaystyle \sin \angle B=\frac{2}{3}=0.667$

Calculating the inverse sine function:

$\angle B=\arcsin (0.667)$

$\boxed{\angle B=41.81^\circ}$

A. Reflection over y = 2

B. Reflection over y axis, reflection over y = 1

C. I'm guessing you just have to draw this one, just put the center on (2,0) and enlarge it by the scale factor

Answer number 2 pleaseeee thank you

Fittoniya [83]

Hi!

a: F n G =(Intersection) {4,6,8,10}

b: F n H ={empty set}

Because there is no common element between the elements of set F and the elements of set H.

Note: It may not be very clear as I don't speak English.

God work!

60>5(6-2x) ok help me so I can get an answer

Dima020 [189]

Inequalities are used to represent unequal expressions

The solution to the inequality is: $x > -3$

<h3>How to determine the inequality solution</h3>

The inequality is given as:

60>5(6-2x)

Rewrite the inequality properly as:

$60>5(6-2x)$

Divide both sides of the inequality by 5

$12>6-2x$

Subtract 6 from both sides of the inequality

$6>-2x$

Divide both sides of the inequality by -2

$-3Rewrite the inequality as[tex]x > -3$

Hence, the solution to the inequality is: $x > -3$
