What is (7/12)/(5/9)? In simplest form..

Answers

Answer 1

Answer: $(7)/(12) / (5)/(9) =$

Change the division to multiplication through the reciprocal of the number being divided.

$(7)/(5) * (9)/(5) = (21)/(20)$

As mixed number:

$1 (1)/(20)$

Answer 2

Answer: 7/12 times 5/9 equals 35/108. It is automatically in simplest form.

i am pretty sure it is B because x is the slope in a graph and 1 can be 1/1 and parrarel means opposite so opposite of x axis is y.
opposite of 1/1 on x axis is opposite of 1/1 on y

1Convert the following equation to slope-intercept formy-3=\frac{1}{8}\left(x+8\right)y−3=8(x+8)

Answers

Answer:

y = 8x + 67

Step-by-step explanation:

The equation of a line in slop- intercept form is

y = mx + c

Given

y - 3 = 8(x + 8) ← distribute parenthesis

y - 3 = 8x + 64 ( add 3 to both sides )

y = 8x + 67 ← in slope- intercept form

Khaliq produces and sells toy cars. The material for each car costs him $4. He has been selling them for $8 each and averaging sales of 40 per week. He has been told by Kiarash that he could charge more but has found that for each $0.50 increase in price, he would lose 4 sales each week. How much should Khaliq charge per car in order to have the greatest profit? What is the greatestprofit?

Quadrilateral ABCD is a kite. A kite. Angle A is 90 degrees, angle B is unknown, angle C is 130 degrees, angle D is unknown. What is the measure of angle B? degrees

Answers

Final answer:

A kite is a quadrilateral with two pairs of adjacent congruent sides. In a kite, the two angles between the congruent sides are equal. To find angle B in this given kite, we can subtract the sum of the other three angles from 360 degrees.

Explanation:

A kite is a quadrilateral with two pairs of adjacent congruent sides. In a kite, the two angles between the congruent sides are equal. In this given kite, angle A is 90 degrees, angle C is 130 degrees, and angle D is unknown. Since the sum of the angles in a quadrilateral is 360 degrees, we can find angle B by subtracting the sum of the other three angles from 360 degrees.

Let's calculate it:

Angle A = 90 degrees
Angle C = 130 degrees
Angle D = (360 - 90 - 130) degrees
Angle B = (360 - 90 - 130 - Angle D) degrees

By substituting the values, we can find that angle D is 140 degrees.

Therefore, angle B is (360 - 90 - 130 - 140) degrees, which simplifies to 0 degrees.
