can someone help me with this please - can you also give a step by step not just an answer
Answer:
The way I was taught to do it is to change value into a total fraction, then multiple the numerators together, multiply the denominators together, and finally reduce as far as possible.
7/9 x 5 2/5 = 7/9 x 27/5 = 189/45 = 4 9/45 = 4 1/5
1 3/4 x 4 1/6 = 7/4 x 25/6 = 175/24 = 7 7/24

How do you find a slope and the Y intercept
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
how do i do sohcahtoha
Answer:
you mean trigonometry i'm assuming
but essentially:
soh = sin theta (the angle) = opposite length/hypotenuse length
cah = cos theta (angle) = adjacent length/hypotenuse length
toa = tan theta (angle) = opposite length/adjacent length

csc^-1 4.25 to degrees
9514 1404 393
Answer:
13.609°
Step-by-step explanation:
The csc^-1 function is the arccosecant function. It gives the angle whose cosecant is given. If we let A represent that angle, your statement is ...
A = csc^-1(4.25)
It is used to solve the relation ...
4.25 = csc(A)
__
Some calculators can give you the value directly (see attached). Most cannot. In any event, you need to make sure the angle mode for the calculator is set to degrees.
When your calculator does not have the csc^-1 function, you can make use of the trig identity ...
csc(x) = 1/sin(x)
In the above equation, this becomes ...
4.25 = 1/sin(A)
sin(A) = 1/4.25 . . . . . solve for sin(A)
All scientific and graphing calculators will have the inverse sine (arcsine) function.
A = sin^-1(1/4.25)
A ≈ 13.609° . . . . . . . calculator mode in Degrees
_____
Additional comment
For inverse functions, especially inverse trig functions, I find it useful to read them as ...
csc^-1(x) ⇒ "the angle whose cosecant is x"
sin^-1(x) ⇒ "the angle whose sine is x"
This reminds me that the value it gives is an angle (degrees or radians), and the argument it takes is a pure number (one with no units).

In the number 15.42, how is the value of the digit "2" different from the value of the digit "2" in the number 12.54?
-3x + -15 = 12
x = __
Answer:
x=9
Step-by-step explanation:
alright so first we eliminate the -15 and to do that we add 15 on both sides:
-3x-15+15=12+15
-3x=27
Now we divide 3 on both sides to make the equation equal to x
[tex] \frac{-3x}{-3} = \frac{27}{-3} [/tex]
x=9
And that's your answer, you're welcome :)

Step-by-step explanation:
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 $700. What selling price should George charge the art gallery if he wants to break even?
Answer:
George should charge 1.70$ 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

Can someone help me out with this question as I’m completely stuck
Answer:
Step-by-step explanation:
∠BEF = ∠ABE {Alternate interior angle}
∠BEF = 60
∠EQR = ∠ BEF {Corresponding angles}
∠EQR = 60
In ΔEQR
∠QER + ∠EQR + ∠ERQ = 180 {angle sum property}
80 + 60 +x = 180
140 + x = 180
x = 180- 140
x = 40

the tiles on cathy's bathroom floor are square shaped and each tile covers an area of 90 square inches. simplify an expression to represent the side length of each tile.
Answer:
[tex]\huge\boxed{\sf L = 3\sqrt{10} }[/tex]
Step-by-step explanation:
Area of a square tile = 90 square inches
Let the side length of tile be "L"
Condition:
Area = 90
L * L = 90
L² = 90
Taking sqrt on both sides
L = √90
L = 3√10
