Y is already solved because y=kt

Do you mean solve
(In)(y)=(k)(t) for y?

If so then all you do is divided (In) on both sides and you'll get

Y=(k)(t)/(In)

The basic thing you need to know when solving for a variable is that you want to make it isolated.

On the other-hand, if you meant how do you solve for y=(k)(t) for y, then it's already solved.

A marker is randomly selected from a drawer that contains 20 green, 44 orange, and 30 blue markers.Which statement is true?

Black_prince [1.1K]

$Probability = \frac{number of choice}{total number of choices}$
# green = 20
# orange = 44
# blue = 30
Total = 20 + 44 + 30 = 94

$P(green) = \frac{20}{94} = 0.212
$
$P(orange) = \frac{44}{94} = 0.468$
$P(blue) = \frac{30}{94} = 0.319$

Solve for z a(t+z)=45z+67

ladessa [460]

Solve for z a(t+z)=45z+67
1. Expand
$at+az=45z+67$

2. Subtract $at$ from both sides
$az=45z+67-at$

3. Subtract 45z from both sides
$az-45z=67-at$

4. Factor out the common term z
$z(a-45)=67-at$

5. Divide both sides by a - 45
$z= \frac{67-at}{ya-45}$

Answer: $z= \frac{67-at}{a-45}$

Four students wrote sequences during math class. Andre mc011-1.jpg Brenda mc011-2.jpg Camille mc011-3.jpg Doug mc011-4.jpg Which

maks197457 [2]

<span>A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

</span>The common ration is obtained by dividing the a term by the preceding term.

Given that f<span>our students wrote sequences during math class with
Andre writing $-\frac{3}{4} ,\frac{3}{8} ,-\frac{3}{16} ,-\frac{3}{32} , . . .$
Brenda writing </span> $\frac{3}{4} ,-\frac{3}{8} ,\frac{3}{16} ,\frac{3}{32} , . . .$
Camille writing $\frac{3}{4} ,\frac{3}{8} ,-\frac{3}{16} ,-\frac{3}{32} , . . .$
Doug writing $\frac{3}{4} ,-\frac{3}{8} ,\frac{3}{16} ,-\frac{3}{32} , . . .$

Notice that the common ratio for the four students is $- \frac{1}{2}$ .

For Andre, the last term is wrong and hence his sequence is not a geometric sequence.
For Brenda, the last term is wrong and hence her sequence is not a geometric sequence.
For Camille, her sequence is not a geometric sequence.
For Doug, his sequence is a geometric sequence with a common ratio of $- \frac{1}{2}$ .

Therefore, Doug wrote a geometric sequence.

Which equation is the inverse of y = 2x2 – 8?

natita [175]

The inverse of the function is $y=\pm \sqrt{\frac{x+8}{2}}$

Explanation:

To find the inverse of the equation $y=2x^{2} -8$ , we need to interchange the variables x and y for the variables y and x.

Thus, the equation becomes

$x=2y^{2} -8$

Now, we shall find the value of y.

Now, adding 8 to both sides of the equation, we have,

$x+8=2y^{2}$

Interchanging the sides,

$2y^{2} =x+8$

Dividing by 2 on both sides,

$y^{2} =\frac{x+8}{2}$

Taking square root on both sides,

$y=\pm \sqrt{\frac{x+8}{2}}$

Thus, the inverse of the function is $y=\pm \sqrt{\frac{x+8}{2}}$

The radius of circle G is 4 cm. What is the tangent

qaws [65]

The tangent of a given circle is perpendicular to the radius a the point called point if tangency. The radius of the circle is perpendicular to the tangent at the point of tangency. This property is especially useful in cases where the radius that connects to the point of tangency forms a part of right angle because the pythagorean theorem and trigonometry apply to right angles.
