A rectangular prism fish tank measures 6.2 cm × 4.7 cm × 2.3 cm.
Find the volume of the fish tank and round to the nearest hundredth if necessary.

Answer:

The angles are 24.6° and 155.4°

Step-by-step explanation:

Supplementary angles add up to 180°

Let the measure of the supplementary angle = x

So, the angle is 130.8 more than 'x'

     The angle = x + 130.8

The angles are supplementary.

x + (x + 130.8) = 180

x + x + 130.8 = 180

  2x + 130.8  = 180

                2x = 180 - 130.8

                 2x = 49.2

                   x = 49.2/2

                   x = 24.6

x + 130.8 = 24.6 + 130.8

                =  155.4

The angles are 24.6° and 155.4°

An angle measures 130.8º more than its supplementary angle. What is the measure of each angle?

[tex]\blue{\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}[/tex]

Supplementary angles add up to 180º.

In order to find the unknown angles, we should first let the angle be x.

Set up an equation:-

(remember, there are 2 angles, x and x+130.8):-

x+x+130.8=180

Add the x's:-

2x+130.8=180

Subtract 130.8 from both sides:-

2x=49.2

Divide by 2 on both sides:-

x=24.6º

To find the other angle, add 130.8º:-

24.6+130.8=155.4º

Second angle=155.4º

Now, we need to make sure our solution is correct.

We can easily check it by adding both angles together and seeing whether or not we end up with 180:-

155.4+24.6=180

180=180

Since the left-hand side equals the right-hand side, our solution is indeed correct.

The angles are 24.6º and 155.4º

Step-by-step explanation:

We dont know how many spinner slots there are so I assume 8.

to get greater than 4 you need the cube which has 6 sides. Only 5 and 6 are > 4. So 2.

Sorry if this is incorrect...

Answer:

≥ means equal or bigger.

So 5x should be equal or bigger than 45.

Which means x can be 9 or 10/11/12...

Answer:

Perimeter: 26.43 m

Area: 27.99 sq m

Step-by-step explanation:

To find the perimeter we just add all the sides, 11.1+9.33+6 = 26.43

To find the area of a triangle, we use the formula we do (bh)/2

9.33 * 6 = 55.98

55.98 / 2 = 27.99

Hope this helped you! I would appreciate a Brainliest if this helped you a lot! Thank you, and have a good day!

Answer:

We first need to determine the perimeter of the triangle which is done by adding up all of the sides.  When combining [tex]11.1\ m[/tex], [tex]9.33\ m[/tex], and [tex]6\ m[/tex] we get a final answer of [tex]26.43\ m[/tex] as the perimeter of the triangle.

The second part that we need to determine is the area of the triangle which is done by using [tex]A=\frac{1}{2}*b*h[/tex].  In this example our base is [tex]6\ m[/tex] and our height is [tex]9.33\ m[/tex].  So when inputting those values into our area equation, we get [tex]A=27.99\ m^2[/tex]

Answer:

153 in^2

Step-by-step explanation:

To find the area of a rectangle, we can multiply the length and the width. The rectangle CDEF has length CF and width FE. We already know FE is the same as GH which is 9in. CF is the hypotenuse of right triangle FGC. Th legs are FG which is the same as EH, 8 and GC, which is the same as AE, 15. Using the pythagorean theorem, we can say that:

GC^2 + GF^2 = CF^2

64 + 225 = CF^2

CF^2 = 289

CF = 17

To find the rectangle's area, we multiply FE and CF to get 153 in^2

Answer:

A. x-intercepts: prices at with profit is zero

    maximum: price at which profit is a maximum

    increasing: (-∞, 3); decreasing: (3, ∞) — profit increases with increasing pen price below $3, decreases with increasing pen price above $3

 B. -26 2/3; loss of profit for each dollar increase in pen price

Step-by-step explanation:

Part A:

The definition of the function tells you what points on the graph represent. The x-intercept at x=0 tells you the company's profit will be zero when the price of pens sold by the company is zero.

The x-intercept at x=6 tells you the company's profit will be zero when the price of pens sold is $6.

The maximum value of 120 at x=3 tells you the company's profit will be $120 when the price of pens sold is $3.

The graph goes "uphill" for x < 3, so the function is increasing for x < 3. The function goes "downhill", so is decreasing, for x > 3. This tells you profit increases with pen price when the price is below $3, and decreases with pen price above $3.

__

Part B:

The equation of the function describing the graph is ...

 f(x) = -120/9x(x -6)

so, at x=5, the value is ...

 f(5) = -120/9(5)(-1) = 600/9 = 66 2/3

Then the average rate of change from x=3 to x=5 is ...

 m = (f(5) -f(3))/(5 -3) = (66 2/3 -120)/2 = (-53 1/3)/2 = -26 2/3

This represents the average change in profit for each dollar increase in the price at which pens are sold.

Answer:

Radiation is the emission and propagation of energy in the form of waves, rays or particles

Step-by-step explanation:

Answer:

∠B=19°

Step-by-step explanation:

At the endpoints of a diameter, angle c meets the circle. It intercepts a 180-degree arc.We know that the measure of C is 90 degrees because the measure of an inscribed angle is half the measure of its intercepted arc. Angles of triangle of ABC must add up to 180.

m∠A+m∠B+m∠C= 180°

71°+m∠B+90°=180°

m∠B+161°=180°

m∠B=19°

Since the two equations are of line and coincident to each other so the equations will have an infinite number of solutions.

The equation which have a degree of one will be called as the linear equation the graph of the equation will be always a straight line.

Here we have the equation:

x-5=-5+x

or

x-5=x-5

Here we can see that the ratios are same:

[tex]\dfrac{a_1}{b_1}=\dfrac{a_2}{b_2}\\\\\\\\\dfrac{1}{-5}=\dfrac{1}{-5}[/tex]

So the equations will be coincident to each other or line one will coincide with line 2. Hence the two equations are of line and coincident to each other so the equations will have an infinite number of solutions.
