At a furniture manufacturer, worker A can assemble a shelving unit in 5 hours. Worker B can assemble the same shelving unit in 3 hours. Which equation can be used to find t, the time it takes for worker A and worker B to assemble a shelving unit together?

Answer:

23.4 in

Step-by-step explanation:

The only side of SFN we know the measurement of is FS, which is 18.2.  We see from the similarity statement that FS corresponds to QB, which is 14.  This gives us the ratio

14/18.2.

From the similarity statement, we see that FN corresponds to QH; this gives us the ratio

18/x

Together this gives us the proportion

14/18.2 = 18/x

Cross multiplying gives us

14(x) = 18.2(18)

14x = 327.6

Divide each side by 14:

14x/14 = 327.6/14

x = 23.4

Answer:

The measure of angle A is 30 degree, measure of angle B is 90 degree and measure of angle C is 60 degree.

Step-by-step explanation:

The measures of given sides are 6, 12, [tex]6\sqrt{3}[/tex].

According to the Law of Cosine:

[tex]\cos A=\frac{b^2+c^2-a^2}{2bc}[/tex]

Using Law of Cosine, we get

[tex]\cos A=\frac{(12)^2+(6\sqrt{3})^2-(6)^2}{2(12)(6\sqrt{3})}[/tex]

[tex]\cos A=\frac{216}{144\sqrt{3}}[/tex]

[tex]\cos A=\frac{3}{2\sqrt{3}}[/tex]

[tex]\cos A=\frac{\sqrt{3}{2}[/tex]

[tex]A=30^{\circ}[/tex]

Similarly,

[tex]\cos B=\frac{a^2+c^2-b^2}{2ac}[/tex]

[tex]\cos B=\frac{(6)^2+(6\sqrt{3})^2-(12)^2}{2(6)(6\sqrt{3})}[/tex]

[tex]\cos B=\frac{0}{36\sqrt{3}}[/tex]

[tex]\cos B=0[/tex]

[tex]B=90^{\circ}[/tex]

Therefore, measure of angle A is 30 degree and measure of angle B is 90 degree.

According to angle sum property, the sum of interior angles of a triangle is 180 degree.

[tex]A+B+C=180^{\circ}[/tex]

[tex]30^{\circ}+90^{\circ}+C=180^{\circ}[/tex]

[tex]C=60^{\circ}[/tex]

Therefore the measure of angle C is 60 degree.

The triangle with sides 6, 12, and 6√3 has angles of 30 degrees, 60 degrees, and 90 degrees.

Given a triangle with sides 6, 12, and 6√3, we can find the angles using the Law of Cosines.

First, we use the formula for the Law of Cosines,
c² = a² + b² - 2ab * cos(C).

Let a = 6, b = 6√3, and c = 12.
We substitute these values into the formula to find angle C,

cos(C) = (6² + (6√3)² - 12²) / (2 * 6 * 6√3)

Compute the values inside the formula:

6² = 36

(6√3)² = 108

12² = 144

cos(C) = (36 + 108 - 144) / 72

cos(C) = 0

Therefore, angle C = 90 degrees.

To find the other angles, we use the Law of Sines,
(sin A / a) = (sin B / b) = (sin C / c).

We already know C = 90°, so (sin C / 12) = 1/12.

For angle A,

sin(A) / 6 = 1/12

sin(A) = 6/12 = 1/2

A = 30 degrees

For angle B:

B = 180° - 90° - 30° = 60 degrees

Therefore, the angles of the triangle are 30 degrees, 60 degrees, and 90 degrees.

Answer:

C 9 inches

Step-by-step explanation:

the set of all whole numbers

f(x)=2x^2-3x+1

the graph of the function is attached with the answer

As we can see that equation is quadratic and its graph is a parabola facing upward.

As we can see it passes the Vertical line test

As it passes the Vertical line test , So it is a function

And two values of x has one value of y

So it is a many to one function.

Using the formula V = πr²h, the volume of the cylinder is calculated as 188.4954 cubic inches, which can be rounded to 188 cubic inches, corresponding to answer choice D.

To calculate the volume of the cylindrical container holding sugar, we can use the formula for the volume of a cylinder, which is V = πr²h. Here, π is a constant (approximately 3.14159), r is the radius of the cylinder, and h is the height of the cylinder.

The diameter of the container is given as 4 inches, so the radius (r) is half of the diameter, which is 2 inches. The height (h) is given as 15 inches. Plugging these values into the volume formula, we get:

V = π(2 inches)²(15 inches)
= π(4 square inches)(15 inches)
= 60π cubic inches

Using 3.14159 as the value for π, the volume calculates to:

V = 60 * 3.14159 cubic inches = 188.4954 cubic inches

So, the closest estimate to the volume of the sugar container would be 188 cubic inches, which corresponds to answer choice D.

Answer:

The dimensions are

[tex]8\frac{1}{2}\ in[/tex]  

[tex]10\frac{5}{8}\ in[/tex]

Step-by-step explanation:

we know that

If two figures are similar, then the scale factor is the ratio of its corresponding sides

step 1

Divide [tex]8\frac{1}{2}[/tex] by [tex]4[/tex]

[tex]8\frac{1}{2}=\frac{8*2+1}{2}=\frac{17}{2}\ in[/tex]

so

[tex]\frac{17}{2}/4=2.125[/tex]

step 2

Divide [tex]11[/tex] by [tex]5[/tex]

so

[tex]\frac{11}{5}=2.2[/tex]

step 3

Find the largest complete enlargement

The scale factor is the smaller of the two previous values

so

The scale factor is [tex]2.125[/tex]

The dimensions are

[tex]4*2.125=8.5=8\frac{1}{2}\ in[/tex]  

[tex]5*2.125=10.625=10\frac{5}{8}\ in[/tex]

Answer:

360°/d = kn.

Step-by-step explanation:

To know if a regular polygon can tessellate, we divide 360 by the interior angle of the polygon and the result needs to be an integer, but not in all cases you get the number of sides of the polygon, you get a multiple of the number of sides. So, none of the options are correct, the correct would be

360/d = kn, where k is an integer.

Just took the test Its C

Using exponential function concepts, it is found that it represents growth of 4%.

An exponential function is modeled by:

[tex]y(t) = y(0)(1 + r)^t[/tex]

In which:

In this problem, the equation is:

[tex]y = 8700(1.04)^t[/tex]

Hence:

[tex]1 + r = 1.04[/tex]

[tex]r = 0.04[/tex]

Since r = 0.04 is positive, it represents a growth of 4%.

To learn more about exponential function concepts, you can take a look at https://brainly.com/question/24757163

Final answer:

The function y = 8700(1.04)^4 represents an exponential growth with a rate of increase of 4% per time period over four periods.

Explanation:

The given function is y = 8700(1.04)^4. This represents an exponential growth because the base of the exponent, 1.04, is greater than 1. To determine the percentage rate of increase, we observe that the base, 1.04, when written as a percentage, is 104%. This means that the amount increases by 4% over each time periodperiod. Since the exponent is 4, this growth occurs over four time periods. However, the overall increase is not simply 4% multiplied by 4, as exponential growth compounds wicompoundsth each time period.

What is the exact value of the trigonometric expression in simplest form? 2 cos(3π/4)−4 sin(7π/6)

[tex] 2 cos(\frac{3\pi}{4})-4sin(\frac{7\pi}{6}) [/tex]

Let us find the value of cos([tex] \frac{3\pi}{4} [/tex]) and [tex] sin(\frac{7\pi}{6} ) [/tex]

[tex] cos(\frac{3\pi}{4} )=cos(\pi -\frac{\pi}{4} ) [/tex]

The angle [tex] \pi -\frac{\pi}{4} [/tex] lies in second quadrant.

So, [tex] cos(\frac{3\pi}{4} )=-cos(\frac{\pi}{4} ) =-\frac{1}{\sqrt{2}} [/tex]

[tex] So, cos(\frac{3\pi}{4} )=-\frac{1}{\sqrt{2}} [/tex]

Now, Let us find the value of [tex] sin(\frac{7\pi}{6} ) [/tex]

[tex] sin(\frac{7\pi}{6} ) =sin(\pi +\frac{\pi}{6} )=-sin(\frac{\pi}{6} ) =\frac{-1}{2} [/tex]

[tex] sin(\frac{7\pi}{6} ) =\frac{-1}{2} [/tex]

[tex] 2 cos(\frac{3\pi}{4})-4sin(\frac{7\pi}{6}) [/tex]=2*[tex] \frac{-1}{\sqrt{2}} [/tex]-4*[tex] \frac{-1}{2} [/tex]

=[tex] \frac{-2}{\sqrt{2}} +\frac{4}{2} [/tex]

=[tex] \frac{-2\sqrt{2}}{2} +\frac{4}{2} [/tex]

=[tex] \frac{-1\sqrt{2}}{1} +\frac{2}{1} [/tex]

=[tex] -\sqrt{2} +2 [/tex]

=[tex] 2-\sqrt{2} [/tex]

[tex] 2 cos(\frac{3\pi}{4})-4sin(\frac{7\pi}{6})=2-\sqrt{2} [/tex]
