Answer:

V = 21145.01 mm³

Step-by-step explanation:

Given that:

The radius of the gumball = 30  mm

The radius of the spherical hollow-core = 28 mm

Consider the radius of the gumball to be [tex]r_2[/tex] and the radius of the spherical hollow-core to be [tex]r_1[/tex]. Then;

The volume of the gumball can be determined by using the formula of a sphere.

[tex]V = \dfrac{4}{3}\pi (r_2^3 - r_1^3)[/tex]

[tex]V = \dfrac{4}{3} \times \pi \times (30^3 - 28^3)[/tex]

V = 21145.01 mm³

Answer:

1. Sides 1 and 2 are congruent so sides 3 are also congruent

2. Since angles D and R are the same and the two sides are the same, the triangles are the same

Answer:

(17, -13) (17, 8) --> In this problem, we use the y2-y1 over x2 - x1 formula.

Step-by-step explanation:

Step 1: Plug In--> 8-(-13)

                            17 - 17

Step 2: Simplify: 21

                             0

Answer: Undefined. Vertical line on graph.

Answer: 21

Step-by-step explanation: The first thing you should have noticed is that x is the same for both coordinates; in other words, x=17, which means there's no change and x, and it will therefore be a straight vertical line. From there, you can find the change in y to determine the slope (because slope is rise over run). Since 8-(-13)=21, the slope is 21.

Step-by-step explanation:

Answer:

Option B.

Step-by-step explanation:

Two triangles can be congruent either by SSS or AAS or ASA or SAS postulates.

AAS is the case where two angles and one corresponding side of a triangle are equal.

For two right angled triangles, we already have one angle congruent as right angle. If another angle is congruent and hypotenuse equal, then the two triangles are congruent.

This directly follows from AAS theorem or AAS postulate

Answer:

i need this asap

Step-by-step explanation:

The equation that models the situation; [tex]y = 148.4 \sqrt {x-1} +154[/tex] Thus, option B is correct.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

A company manufactures acoustic guitars.

The table shows the number of units that the company sold each month over a nine-month period beginning in January, that is;

Month, x 1 2 3 4 5 6 7 8 9

Units, y 150 300 380 425 425 480 520 550 575

If we put x = 2

[tex]y = 148.4 \sqrt {2-1} +154\\\\y = 148.4 +154 = 302.4[/tex]

Y = 300 ( approx)

We can see that the equation that models the situation;

[tex]y = 148.4 \sqrt {x-1} +154[/tex]

Thus, option B is correct.

Answer:

C) the triangles are congruent

Step-by-step explanation:

Answer:

c. the triangles are congruent

Step-by-step explanation:

Both the triangles are right triangles which means the square thing at the bottom corner of the triangles are 90 degrees. So with this info, a triangle is 180 degrees, and one of the triangles already gave u one of the corners degrees so

90 + 59 + x =180

149 + x = 180

x = 31, so now the left triangle is solved. Now see the 118 degrees in the middle? A straight line is 180 degrees so with this in mind,

31 + 118 + x = 180

149 + x = 180

x = 31

The right triangle also has 31 and 90 as two of its angles, we don't need to calculate to know the last angle left is 59 like the left triangle. Therefore both triangles are congruent as they are the same.
