Point G, located at (-5, 6) is rotated 270° counterclockwise. Find the coordinates of G' after the rotation.
(5,-6)
The coordinates of G' after the rotation = (6, 5)
In this question we have been given a point G, located at (-5, 6) is rotated 270° counterclockwise.
We need to find the coordinates of G' after the rotation.
a point (-5, 6) is located in the second quadrant.
First 90° counterclockwise rotation gives (-6, -5) because x & y are interchanged and in Quadrant III both coordinates will be negative.
Second 90° counterclockwise rotation yields (5,-6) because x & y are interchanged and in Quadrant IV the y coordinate will be negative.
Last 90° counterclockwise rotation yields (6, 5) because x & y are interchanged and in Quadrant I both coordinates will be positive.
Therefore, the coordinates of G' after the rotation = (6, 5)

A housepainter mixed 5 gal of blue paint with every 9 gal of yellow paint in order to make a green paint. Which ratio of gallons of blue paint to gallons of yellow paint will NOT make the same shade of green paint?
The ratio of gallons of blue paint to gallons of yellow paint will NOT make the same shade of green paint 4:9.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
A housepainter mixed 5 gal of blue paint with every 9 gal of yellow paint.
So, the ratio of gallons of blue paint to gallons of yellow paint is

in a study, physicians were asked what the odds of breast cancer would be in a woman who was initially thought to have a 1% risk of cancer but who ended up with a positive mammogram result (a mammogram accurately classifies about 80% of cancerous tumors and 90% of benign tumors.) what is the probability of a woman having a malignant (cancerous) tumor in her breast if she has a positive mammogram result? round to 3 decimal places as needed.
The probability that a woman has a malignant tumor in her breast is 7.5%. ie 75
Let + = mammogram result is positive
B = tumor is benign
M = tumor is malignant.
Note that Bc = M.
given that P(M) = .01,
so P(B) = 1 − P(M) = 0.99.
We are also given the conditional probabilities
P(+ | M) = .80 and
P(− | B) = .90, where the event − is the complement of +
P(+ | B) = .10
Bayes’ formula:-
P(M | +) = P(+ | M) P(M) / (P(+ | M)P(M) + P(+ | B)P(B))
= 0.80 × 0.01 / (0.80 × 0.01 + 0.10 × 0.99)

What is the angle addition postulate?The angle addition postulate states that the when two angles are placed side by side such that they share a common ray, the measure of the angle formed by the two angles is the sum of the measure of the individual angles.
∠ABD = ∠ABC + ∠CBD (angle addition postulate)
∠ABD = 90° (definition of right angle)
∠ABC + ∠CBD = 90° (substitution property of equality)
∠ABC and ∠CBD are complementary (definition of complementary)
Similarly
∠CBE = ∠CBD + ∠DBE (angle addition postulate)
∠CBE = 90° (definition of right angle)
∠CBD + ∠DBE = 90° (substitution property of equality)
∠CBD and ∠DBE are complementary (definition of complementary)
∠ABC is a complementary angle to ∠CBD and ∠DBE is a complementary angle to ∠CBD
Therefore;
∠ABC is congruent to ∠DBE (congruent complements theorem)
∠ABC ≅ ∠DBEThe congruent complement theorem states if an angle ∠A is a complement to an angle ∠C and if an angle ∠B is also a complement of angle ∠C then ∠A is congruent to ∠B.

If m ZABD = 75° and m/ABC = 40°,
then mZCBD = [?]°
We see BC is in the middle of the lines AB and BD, therefore mABC + mCBD = mABD.
We're given mABD = 75, mABC = 40.
Therefore, mCBD = mABD - mABC = 75 - 40 = 35.
Answer:
∠CBD = 35°
Step-by-step explanation:
We are told in the question that m∠ABD = 75° and m∠ABC = 40°. We are then asked what the value of m∠CBD is.
As we can see from the diagram, ∠ABD is made up of the angles ABC and CBD. Therefore:
∠ABD = ∠ABC + ∠CBD
⇒ 75° = 40° + ∠CBD
⇒ 75° - 40° = 40° + ∠CBD - 40° [
⇒ 35° = ∠CBD
∴ ∠CBD = 35°
The line graphed below has a slope equal to -2. The point (3, 28) lies on
this line as shown. Determine the y-value on this line when the x-value is
equal to 11.
Answer:
y = 12
Step-by-step explanation:
We'll use the form of an equation of a straight line of y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
We are told the slope, m, is -2.
That leads to: y = -2x + b
y = -2x + b
B, the y-intercept, can be found by using the given point (3,28) in the equation (it falls on the line, so must be a valid solution to the equation. Use the given x and y in the equation and solve for b:
y = -2x + b
28 = -2*(3) + b
28 = -6 + b
b = 34
The equation is y = -2x + 34
Use this to find y when x = 11:
y = -2(11) + 34
y = -22 + 34
y = 12
y is 12 when x is 11

Answer:
164 minutes
Step-by-step explanation:
$8 + $0.06m = $17.84

What is the nature of roots?
The nature of the roots of the quadratic can fall into one of three categories depending on the value of the discriminant
Δ > 0 means there are 2 distinct real roots.
Δ = 0 means there are 2 equal real roots or 1 distinct real root.
Δ < 0 means there are no real roots, but 2 complex roots.
Here,
The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

Part a: Monthly percent rate = y/x
Part b: APR = y/x × 12.
What is meant by the term APR?The annual interest produced by a sum that is paid to investors or charged to borrowers is referred to as the annual percentage rate (APR). APR is a percentage that expresses the actual annual cost of borrowing money over the course of a loan or the income from an investment. An APR might not accurately represent the cost of borrowing but since lenders have some latitude in determining it, excluding some fees.APR and APY (annual percentage yield), a computation that takes interest compounding into account, should not be confused.For the given question;
Average daily balance sheet of Suzanne's is x dollars.
Finance charges = y
Part a: monthly percentage rate
Finance charge = Monthly percent rate × Average daily balance
Monthly percent rate = Finance charge/Average daily balance
Monthly percent rate = y/x
Part b: APR
The annual percentage rate (APR) is calculated by dividing the periodic interest rate even by number of periods in the year that it was in effect. The number of times the rate is applied to a balance is not stated.Thus,
