what is equivalent to sin10cos25-cos10sin25
Answer:
- 0.2588
Step-by-step explanation:
Theory: sin(a - b) = sin(a)*cos(b) - cos(a)*sin(b)
In this case a stands for 10 AND b stands for 25
Hence:
sin10cos25-cos10sin25 = sin (10 - 25) = sin (-15) = - sin(15) = - 0.2588
Which choice is equivalent to the quotient below?
√36/√4
A. √2/2
B. 3
C. 9
D. √12

A retailer’s gross margin on a $150 item is $40. Calculate GMC as a percentage.
The gross margin cost for the case when the considered retailer’s gross margin on a $150 item is $40 is 26.67% approximately.
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
Given that:
The cost of the considered item = $150The gross margin of retailer on that item = $40Here we assume that the term GMC is referring to gross margin cost.
Let this gross margin cost (GMC) $40 be P% of the original cost of the item $150.
Then, we get:
[tex]p = \dfrac{40}{150} \times 100 \approx 26.67 \text{(in percentage)}[/tex]
Thus, the gross margin cost for the case when the considered retailer’s gross margin on a $150 item is $40 is 26.67% approximately.

Answer:
x = 19
Step-by-step explanation:
The work shown is almost complete. It can be finished by multiplying both sides of the equation by the inverse of the coefficient of x.
x-coefficient: -1/3
inverse of x-coefficient = 1/(-1/3) = -3
Then you have ...
[tex]-3\left(-\dfrac{19}{3}\right)=-3\left(-\dfrac{1}{3}x\right)\\\\19=x\qquad\text{simplify}\\\\\boxed{x=19}[/tex]

A cylinder has a height of 15 inches. Its volume is 3,014.4 cubic inches. What is the radius of the cylinder?
Use ≈ 3.14 and round your answer to the nearest hundredth
Answer:
Radius = 8in
Step-by-step explanation:
[tex] \hookrightarrow \sf \: V = {\pi r}^{2} h[/tex]
Where,
v = 3014.4h = 15π = 3.14⇢ 3014.4 = (3.14)(r²)(15)
⇢ 3014.4 = (r²)(47.1)
⇢ 3014.4 = 47.1r²
⇢ 3014.4/47.1 = 47.1r²/47.1
⇢ 64 = r²
⇢ r = √64
⇢ r = 8
[tex] \therefore [/tex] The value of radius is 8 inches

If u give answer ill give 100 points NOT FAKE PLS I NEED HELP
Answer:
86 Degrees
Step-by-step explanation:
First we need to apply the defenition of a Supplementary Angle: A supplrementary angle means an angle whos measure is 180degrees.
As we are given two angles labled supplementary we must know that angleA + angleB = 180degrees.
Now we are given two equations for the measure of each angle.
measure of A = 6x+10
measure of B = 4x+30
We simply plug this into the first equation I've stated above.
6x+10 + 4x+30 = 180
Simplify
10x+40 = 180
10x = 140
x = 14
Now that we have X, we plug this into the measure B equation to get the measure.
4x + 30
(Plug 14)
4(14) + 30
56 + 30
86 Degrees

Two cubes have edge lengths of 9 cm and 3 cm, respectively. What is the difference in volume of the two cubes?
1. 243 cm3
2. 756 cm3
3. 27 cm3
4. 702 cm3
The difference in volume of the two cubes is 702 cm3
Step-by-step explanation :
Given-
Length of edge of one cube = 9 cmLength of edge of second cube = 3 cmNow, The formula for finding volume of any cube is -
[tex] \underline{ \boxed{ \mathfrak \red{volume \: of \: cube = {edge}^{3} }}}[/tex]Therefore, substituting values. . .
Volume of one cube = [tex] {(9)}^{3} [/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: = 9 \times 9 \times 9[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 729 \: {cm}^{3} [/tex]
Similarly,
Volume of second cube [tex] = {(3)}^{3} [/tex]
[tex] \: \: \: \: \: \: \:\: \: \: \:\: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \:\: \: \: \: \: \: = 3 \times 3 \times 3[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \:\: \: = 27 \: {cm}^{3} [/tex]
Now,
Difference in volume of two cubes = Volume of 1st cube - Volume of 2nd cube
[tex] \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \:= (729 - 27) {cm}^{3} [/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 702 \: {cm}^{3} [/tex]
Thus, the difference in volume of the two cubes comes out 702 cm3
What fraction shows what each person gets if 9 friends share 5 apples?
Answer: 5/9 of an apple
Step-by-step explanation:
Since there are more people than apples, you know that the aples are going to be cut and every person will get less than one apple. You just divide the 5 apples to the 9 people. The simple way is putting the numbers and making it a fraction. In this case, 5/9. 5 apples as the numerator and 9 people as the demoninator.
12+ b/6 = 16 what is the variable?

[tex]\frac{b}{6} = 4[/tex]
Step 2: Multiply both sides by 6
[tex]\frac{b}{6} * 6 = 4 * 6[/tex]
[tex]b = 24[/tex]

Find the area of the figure.EXPlAIN THE STEPS!!!!
Answer:
30.56 yd²
Step-by-step explanation:
To determine the area of the composite shape, we need to:
Divide the shape into two smaller "known" shapes (Refer to image). Determine the area of those "known" shapes. Add the area of the known shapes to obtain the area of the figure.Determining the area of shape 1 (Rectangle 1):
⇒ Area of rectangle = Lenght × Breadth
⇒ = 2.1 × 4.8
⇒ = 10.08 yd²
Determining the area of shape 2 (Rectangle 2):
⇒ Area of rectangle = Lenght × Breadth
⇒ = 6.4 × 3.2
⇒ = 20.48 yd²
Determining the area of the figure:
⇒ Area of figure = Area of rectangle 1 + Area of rectangle 2
⇒ = 10.08 + 20.48
⇒ = 30.56 yd²

To answer wait you put into the big, it would be .28 since when making a percentage a decimal you move the decimal point to the left twice. There is always an invisible decimal after a whole number (ex. 28.0). And to find out what 28% of 140 is you simply do .28 x 140 to find that, which is 39.2.

Elimination
Explanations are given below
Step-by-step explanation:
Hello!
1) SubstitutionThis is because you already have a solution for a variable, y, and you can simply plug in the value of y for the second equation
2) SubstitutionThe same thing as above, you already have the value of y, and you can simply plug it into the second equation.
3) EliminationYou should use elimination because you can simply eliminate the variable y by adding the two equations, as they have the same coefficient of 3.
4) EliminationSame as above, simply add the two equations to eliminate x, because they have the same coefficients of 7.
5) SubstitutionYou have the value for y, so simply plug it into the other equation to solve for x.
6) EliminationYou have -2x in both equations, and subtracting the equations will eliminate the variable x, and you can then solve for y.

Tory and Emilio's motorboats travel at the same speed. Tory pilots her boat 30 km before docking. Emilio continues for another 2 hr, traveling a total of 80 km before docking. How long did it take Tory to navigate the 30 km?
Answer:
1.2 hours
Step-by-step explanation:
first im going to assume both travel at a constant speed the entire time
both motorboats travel 30 km, so emilio travels another 50 (80-30 = 50) km in 2 hours. speed = distance/time so the speed of the motorboats is 50/2 or 25km/h
divide 30 by 25 to get 1.2hours
