Answer:

<1 = 45

<2 = 50

Step-by-step explanation:

Let <1 = x

Let <2 = y

=============

x + y = 95

y = 2*x - 40

=============

I think the easiest way to do this is to substitute the second or bottom equation into the top equation. Substitute for y

x + 2x - 40 = 95                    Combine like terms on the left.

3x - 40 = 95                          Add 40 to both sides.

3x -40+40 = 95+40              Combine

3x = 135                                 Divide by 3

x = 45

=================

Now use the top equation to solve for y

x + y = 95

45 + y = 95                             Subtract 45 from both sides.

45 - 45 + y = 95 -45               Combine

y = 50

Answer:

Demand: q = -50p + 1200

Supply: q = 40p

Step-by-step explanation:

First let's define our variables.

q = quantity of T-shirts

p = price

We know that when p = 12, q = 600.  When p increases by 1, q decreases by 50.  So this is a line with slope -50 that passes through the point (12, 600).  Using point-slope form to write the equation:

q - 600 = -50 (p - 12)

Converting to slope-intercept form:

q - 600 = -50p + 600

q = -50p + 1200

Similarly, we know that when p = 9.75, q = 600 - 210 = 390.  When p increases by 1, q increases by 40.  So this is a line with slope 40 that passes through the point (9.75, 390).  Using point-slope form to write the equation:

q - 390 = 40 (p - 9.75)

Converting to slope-intercept form:

q - 390 = 40p - 390

q = 40p

Answer:

Answer is 81y^4z^4

Step-by-step explanation:

The expression is (-3yz) (-3yz) (-3yz) (-3yz).

Since all the four terms have power 1:

(-3yz)^1 (-3yz)^1 (-3yz)^1 (-3yz)^1

We know that we can add the powers if the terms have same base

So,

=(-3yz)^1+1+1+1

=(-3yz)^4

=(-3)^4(y)^4(z)^4.

If the power is an even number than the negative sign changes into positive sign.

=3^4y^4z^4

=81y^4z^4

Thus the answer is 81y^4z^4....

Answer:

3619.11 cubic inches

Step-by-step explanation:

volume of a cylinder is [tex]V=\pi r^2h[/tex]

diameter is 16 in, so radius (r) is 8 in

plug in values: [tex]V=\pi 8^2(18) = 3619.11[/tex] cubic inches

The volume of a cylinder with a diameter of 16 inches and a height of 18 inches is calculated using the formula V = πr²h, which results in approximately 3617.3 cubic inches when rounded to the nearest tenths place.

To calculate the volume of a cylinder, we use the formula V = πr²h. Given that the diameter of the cylinder is 16 inches, which means its radius (r) is half of that, 8 inches. The height (h) of the cylinder is given as 18 inches. To find the volume, first square the radius, then multiply by π (approximated as 3.14 for this purpose), and then by the height.

So, the calculation looks like this:

Therefore, the volume of the cylinder, rounded to the nearest tenth place, is 3617.3 cubic inches.

Answer:

D

Step-by-step explanation:

we can use the formula of tan(A-B) to solve this equation .

The formula is

[tex]tan(A-B)= \frac{tanA-tanB}{1+tanA.tanB}[/tex]

In our question , A is x and B is [tex]\frac{\pi }{3}[/tex]

so when we apply these in the question we get

[tex]tan(x-\frac{\pi }{3} )=\frac{tanx-tan\frac{\pi }{3} }{1+tanx.tan\frac{\pi }{3} }[/tex]

Now since [tex]tan\frac{\pi }{3} = \sqrt{3}[/tex]

we get

[tex]tan(x-\frac{\pi }{3} )=\frac{tanx-\sqrt{3}  }{1+\sqrt{3} tanx.} }[/tex]

so correct option is

Step-by-step explanation:

The Law of Sines states the relationship between the sides and the angles of non-right (oblique) triangles.

In the given triangle,the following relation holds;

[tex]\frac{4.7}{sin(95)}=\frac{a}{sin(40)}\\\\a=\frac{4.7}{sin(95)}*sin(40)\\\\a=3.03[/tex]

Answer:

Option C. a = 3.0 cm

Step-by-step explanation:

We have to find the value of a from the given triangle ABC.

By applying sine rule in ΔABC

[tex]\frac{sin95}{4.7}=\frac{sin40}{a}[/tex]

Now we cross multiply in the given equation.

a(sin95°) = 4.7(sin40°)

a(0.9962) = 4.7(0.6428)

a = [tex]\frac{4.7(0.6428)}{0.9962}[/tex]

a = 3.03 cm ≈ 3.0 cm

Therefore, a = 3.0cm Option C. will be the answer.

Answer: (It didn't say what to have the units in so I assumed as is)

(pm) 5sqrt(6)/2

(pm) 6.12372           (rounded version)

Step-by-step explanation:

F=mv^2/r  (Given)

rF=mv^2    (Multiply both sides by r)

rF/m=v^2   (Divide both sides by m)

v=(pm) sqrt(rF/m)  (Square root both sides)-(pm means plus or minus)

v=(pm) sqrt(rF)/sqrt(m)  

v=(pm) sqrt(rF)sqrt(m)/m   (I had multiply top and bottom by sqrt(m))

v=(pm) sqrt(rFm)/m

*sqrt( ) means square root of whatever is in the (  ) that follows the sqrt

Now find v if F=50, m=100 kg, and r=150/2=75 so plug in

v=(pm) sqrt(75*50*100)/100

v=(pm) sqrt(375000)/100  OR

v=(pm) sqrt(100*25*3*25*2)/100

v=(pm) 10*5*sqrt(3)*5*sqrt(2)/100

v=(pm) 250sqrt(6)/100

v=(pm) 2.5sqrt(6)

v=(pm) 5sqrt(6)/2

Or if you want a decimal number rounded, it would be (pm) 6.12372

The formula for calculating the centripetal force of an object in circular motion can be rearranged to find velocity. You compute the tangential velocity of a 100kg object with a force of 50N, moving on a circular path with a diameter of 150m, by plugging these values into this rearranged formula. This calculation results in a value of approximately 61.24 m/s for the tangential velocity of the object.

The formula F=mv^2/r calculates the centripetal force (F) of an object of mass (m) moving in a circular path with a radius (r). You can solve this formula for velocity (v) by first multiplying both sides by r, making the formula Fr=mv^2. Then, divide both sides by m, which makes the formula Fr/m = v^2. Finally, take the square root of both sides to get v = √(Fr/m).

To calculate the tangential velocity of a 100kg object with a force of 50 Newton, moving along a circular path with a diameter of 150 meters, you must first divide the diameter of the circle by 2 to get the radius, 75 meters. Next, substitute the given values into the formula; v = √((50N * 75m) / 100kg). Therefore, the tangential velocity is approximately √(3750N·m/kg) = 61.24 m/s.

Answer:

Julie=35 lbs, Ted= 70 lbs, and Mike=105 lbs

Step-by-step explanation:

Julie=x ted=2x mike=3x

The sum of their weight all together is 210 pounds

Combine the x's

6x=210

Divide both sides by 6 to get 1x (Julies weight)

6x/6 = 210/6

1x= 35 (Julie weighs 35 lbs)

35 x 2= 70 ( Ted weighs 70 lbs)

35 x 3= 105 ( Mike weighs 105 lbs)

Answer:

B

Step-by-step explanation:

Circumference of a circle is:

C = 2πr

Area of a circle is:

A = πr²

The circumference of the well is 47 ft and the area of the well in the drawing is 0.641 cm².  If we say r is the radius of the circle on the drawing in centimeters and R is the actual radius of the well in feet, then:

47 = 2πR

0.641 = πr²

Solving for each:

R = 47 / (2π) ≈ 7.48 feet

r = √(0.641 / π) ≈ 0.452 cm

The scale is the ratio of R / r:

R / r = (7.48 ft) / (0.452 cm) = 16.6 ft/cm

So 1 cm = 16.6 ft.

This isn't one of the options.  Are you sure you copied the problem correctly?

Maybe you meant that the circumference is 4π feet, and the area is 0.64π cm².  If so:

R = 4π / (2π) = 2 feet

r = √(0.64π / π) = 0.8 cm

R / r = (2 feet) / (0.8 cm) = 2.5 ft/cm

So 1 cm = 2.5 ft.

a^2 + 36 = 100

a^2 = 64

a = 8

For this case we must find an expression equivalent to:

Answer:

So ordered pair a is (2,11)

Step-by-step explanation:

We are given

a = b+c

and ordered pair b =(6,3) and ordered pair c =(-4,8)

Putting values of b and c in the given equation and adding x and y coordinates of b and c we can find ordered pair a.

a=(6,3)+(-4,8)

a =(6-4,3+8)

a =(2,11)

So ordered pair a is (2,11)

We don't get to see the figure but we don't need it.

The remaining angle B is

B = 180 - 27 - 78 = 75°

The Law of Sines gives the remaining sides

[tex]\dfrac{a}{\sin A} =\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

[tex]a = \dfrac{b \sin A}{\sin B} = \dfrac{66 \sin 27}{sin 75} \approx 31.0203[/tex]

[tex]c = \dfrac{b \sin C}{\sin B} = \dfrac{66 \sin 78}{sin 75} \approx 66.8350[/tex]

Answer: B=75°, a=31.0, c=66.8
