What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
For 3 dozen cookies = 1 1/2 cups = 3/2 cups
For 1 dozen cookies = 3/2 * 1/3 = 1/2 cups needed
So, for 7 dozen cookies = 1/2 * 7
= 3 1/2 cups needed
Hence, for 7 dozens cookies 3 1/2 cups needed.

Find the exact values of the remaining five trigonometric functions of o satisfying the given conditions.
cos θ=3/5, tan θ < 0
Answers
First, tan(θ) = sin(θ) / cos(θ), so if cos(θ) = 3/5 > 0 and tan(θ) < 0, then it follows that sin(θ) < 0.
Recall the Pythagorean identity:
sin²(θ) + cos²(θ) = 1
Then
sin(θ) = -√(1 - cos²(θ)) = -4/5
and so
tan(θ) = (-4/5) / (3/5) = -4/3
The remaining trig ratios are just reciprocals of the ones found already:
sec(θ) = 1/cos(θ) = 5/3
csc(θ) = 1/sin(θ) = -5/4
cot(θ) = 1/tan(θ) = -3/4
How do you find a slope and the Y intercept
Answers
Answer:
Step-by-step explanation:
Typically in a line the y intercept is the point where your graph crosses the y-axis, and the x value is 0 so (0,b) is the y-intercept where y-intercept is b
The slope can be found by finding the rate of change, so the change in y / the change in x
You can also calculate the slope with 2 points so (x1, y1) (x2, y2)
you take the y values and subtract them, then divide by the x values like this:
y2 - y1 / x2 - x1
If a line is going up to the right in Quadrant I then the slope is positive, if the slope of the line goes down in Quadrant IV then the line slope is negative
Slopes of horizontal lines are zero, the slope of a vertical line is undefined
We use the letter m to stand for the slope

George is required to produce 500 frames for an art gallery. He spent $100 on the wood required for all these frames. He also spent $50 in polishing all the final frames. He rented two floors of an art gallery for about $700. What selling price should George charge the art gallery if he wants to break even?
Answers
Answer:
George should charge 1.70$ for each frame to break-even.
Step-by-step explanation:
Variable cost for the frames:
Wood + polishing = $100 + $50 = $150
Variable cost per frame would be:
$150/ 500 = $0.30
The fixed cost of the operation is $700.
George has to make 500 frames.
Fixed cost / (Selling price per unit – variable cost per unit) = 500
$700 / (Selling price per unit - $0.30) = 500
700 = 500 (Selling price per unit – 0.30)
700 = 500 * Selling price – 500 * 0.3
700 = 500 * Selling price – 150
(700 + 150) / 500 = Selling price
850 / 500 = 1.7

Explanation:
The work can be done in your head, so there's really nothing to show.
If you want to go into painful detail, you can do this ...
[tex](2\sqrt{3x})(3\sqrt{6x^2})=(2\sqrt{3x})(3x\sqrt{6})=6x\sqrt{3\cdot6x}\\\\=6x\sqrt{3^2\cdot2x}=6x\cdot3\sqrt{2x}=\boxed{18x\sqrt{2x}}[/tex]
There may be some other intermediate steps you can show, or you can combine steps to the extent you think is appropriate.
The measures of the angles of Triangular garden are in the ratio 2:5:5. What are the measures of the angles? Classify the triangle based on its sides
Answers
Answer:
We know that the sum of all the interior angles of a triangle is always equal to 180°.
And we know that the angles are in a ratio of:
2:5:5
So if we have an angle (unknown) θ, the angles of this triangle will be written as:
2*θ
5*θ
5*θ
Now remember that the sum of the 3 angles is equal to 180°, this leads to:
2*θ + 5*θ + 5*θ = 180°
Now we can solve this for θ
(2 + 5 + 5)*θ = 180°
12*θ = 180°
θ = 180°/12 = 15°
This means that the angles of this triangle are:
2*θ = 2*15° = 30°
5*θ = 5*15° = 75°
5*θ = 5*15° = 75°
Now we want to classify this triangle based on this, we have two equal angles, which implies that we must have two equal sides and another different side.
Then this is an isosceles triangle.

Step-by-step explanation:
Since you read 3 pages on Monday and you read 3 times that number on Tuesday, the equation should be 3*3 to equal 9. Then, since you read 9 pages on Tuesday and 3 times that number on Wednesday, the equation should be 9*3 to equal 27 pages. So, on Wednesday, you read 27 pages in total.

27 pages
Step-by-step explanation:
Monday=3 pages
Tuesday=3 pages × 3
=9 pages
Wednesday=9 pages × 3
=27 pages
