Which expression has a positive quotient?
Negative three-fourths divided by Negative two-thirds
Negative StartFraction 1 over 8 EndFraction divided by 3 and one-fifth
2 and StartFraction 2 over 7 EndFraction divided by negative one-fifth
Negative 6 divided by Five-thirds
Answer:
Only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.
Step-by-step explanation:
We will solve to find out Which expression has a positive quotient.
We know the division rule: [tex]\frac{-a}{-b}=\frac{a}{b}[/tex] and [tex]\frac{-a}{b}=\frac{-a}{b}[/tex]
We will use these rules
1) Negative three-fourths divided by Negative two-thirds
[tex]=\frac{-\frac{3}{4} }{-\frac{2}{3} }\\=-\frac{3}{4}\times -\frac{3}{2}\\=\frac{9}{8}[/tex]
The quotient is positive.
2) Negative StartFraction 1 over 8 EndFraction divided by 3 and one-fifth
[tex]\frac{-\frac{1}{8} }{3\frac{1}{5} }\\=\frac{-\frac{1}{8} }{\frac{16}{5} }\\=-\frac{1}{18} \times \frac{5}{16}\\=-\frac{5}{288}[/tex]
The quotient is negative.
3) 2 and StartFraction 2 over 7 EndFraction divided by negative one-fifth
[tex]\frac{2\frac{2}{7} }{-\frac{1}{5} }\\= \frac{\frac{16}{7} }{-\frac{1}{5} }\\=\frac{16}{7} \times -5\\=-\frac{80}{7}[/tex]
The quotient is negative.
4) Negative 6 divided by Five-thirds
[tex]\frac{-6}{\frac{5}{3} }\\=-6 \times \frac{3}{5}\\=-\frac{18}{5}[/tex]
The quotient is negative.
So, only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.

Given that cosA = -8/17 and sinA is negative, determine the value of tanA.
Answer:
tan A = -15/8.
Step-by-step explanation:
sin^2a = 1 - cos^2A
= 1 - (-8/17)^2
= 225/289
So sin A= 15/17
tan A = sin A / cos A
= 15/17 / -8/17
= 15/-8
= -15/8.

Step-by-step explanation:
A company purchased equipment for $150,000 by paying $50,000 and signing a $100,000 note payable. The entire $150,000 is reported as a cash outflow in the financing section of the statement of cash flows.
Answer: False
Step-by-step explanation:
The financing section deals with only the transactions that have to do with equity and debt. The Investing section deals with capital expenditure such as fixed assets and investments in other company securities.
The $50,000 should therefore be recorded in the Investing section as a Cash outflow.
The $100,000 is not a cash transaction but will be recorded in the Notes to the Statement of Cashflows as a Non-Cash transaction for disclosure purposes.

When you multiply a function by –1, what is the effect on its graph?
A.
The graph flips over the y-axis.
B.
The graph flips over the line y = x.
C.
The graph flips over the x-axis.
Answer: C) The graph flips over the x axis.
This is because we're multiplying the y outputs by -1, to make them flip in sign from positive to negative (or vice versa).
Let's say the point (1,2) is on the f(x) curve. Multiplying y = f(x) by -1 will make the point turn into (1,-2). Apply this logic to every point on the f(x) curve and we end up with f(x) reflected over the horizontal x axis.
The notation we could write is either g(x) = -1*f(x) or g(x) = -f(x).
Devon has 14 steel balls of equal weight. If he puts 8 of them in one pan of a balance, and the rest along with a weight of 20 grams in the other pan, the pans balance each other. Which equation can be used to find the weight of each steel ball?

Answer: d = 5/8
Step-by-step explanation:
first, you divide both sides.
16d / 16 = 10 / 16
then, you divide and rewrite.
d = 16/10
then, reduce the fraction.
d = 5/8

Help asap please!! I will mark you as brainliest :)
Answer:
12Step-by-step explanation:
The answer is 12 because is you subtract 2 by 12 then you get 10.
Here's why that's correct.
[tex]\frac{5}{2}[/tex] [tex]or[/tex] [tex]2.5[/tex] is equal to [tex]\frac{10}{4}[/tex] which is also [tex]2.5[/tex]
This is correct because if you multiply both the numerator and the denominator by 2, you get [tex]\frac{10}{4}[/tex] because if you multiply 5 times 2, that equals 10. Then if you multiply 2 times 2, you get 4, which eventually makes 10 over 4, or [tex]\frac{10}{4}[/tex].
Hope this helps! <3

Triangle ABC has side lengths 8 cm, 17 cm, and x cm. The side length of x is shorter than the longest side. What does the value of x need to be in order for the triangle to be considered a right triangle?
Answer:
8 cm and 15 cm
The measure of the side is 15 cm
The measure of the right angle triangle is 8 cm, 15 cm and 17 cm
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle BC = 8 cm
The height of the triangle be AB = x cm
The hypotenuse of the triangle AC = 17 cm
So , for the triangle to be a right angle triangle ,
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Substituting the values in the equation , we get
AC² = AB² + BC²
So , AB² = AC² - BC²
On simplifying the equation , we get
AB² = 17² - 8²
AB² = 289 - 64
AB² = 225
Taking square roots on both sides of the equation , we get
AB = 15 cm
Therefore , the value of x is 15 cm
Hence , The measure of the side is 15 cm
The measure of the right angle triangle is 8 cm, 15 cm and 17 cm

in exercise 4 and 5 find the unkown or marked angles
Answer:
Ф = 110°, β = 110°
Step-by-step explanation:
∠Ф and the 110° angle are corresponding angles since the vertical lines are parallel and a horizontal line cut across both lines. Thus Ф = 110°.
∠β and ∠Ф are alternate angles since the horizontal lines are parallel and a vertical line cut across both lines. Thus Ф = 110° and ∠β = 110°.
