The slosh-out water is 29.9 cubic cm.
What is volume?Volume is defined as the space covered by any solid body in the three-dimensional plane. For the cylinder, the parameters are height and radius.
The volume of the cone is calculated as:-
V = ⅓r^2h
V = ⅓r^2h
V = ⅓(3.5)^2(7)
V = ⅓(12.25)(7)
V = 1/3(85.75)
V = 85.75/3
1/3 cup of water is sloshed out:
Sloshed water = (85.75/3 )/3
Sloshed water = 29.9 cubic cm
Therefore, the sloshed-out water is 29.9 cubic cm.

The statement "RST and ZXY are similar" means that the two triangles have the same shape but possibly different sizes.
Similarity means that corresponding angles are congruent and corresponding sides are proportional.
Now,
If Triangle RST was dilated to create Triangle ZXY, it means that Triangle ZXY is an enlarged or reduced version of Triangle RST, with the same shape and proportions.
This is because dilation is a transformation that changes the size of a figure while preserving its shape.

Round your answer to the nearest tenth.
Using Pythagorean theorem and trigonometric ratio, the resultant vector is 30.72km and the angle between is 53.1°
What is the angle of the balloon's resultant vector?To determine the balloon's resultant vector, we can use the concept of Pythagorean theorem;

Step-by-step explanation:
First you take 3x times 2x since its the first of both equations, which will give you 6x squared.

Then the inner, -2 times 2x which is -4x

You are going to paint a six-sector spinner. There are 4 colors to choose from. How many different ways can you paint the spinner if each color can be used more than once and no two adjacent sectors can be the same color?
Using the Fundamental Counting Theorem, it is found that there are 648 ways to paint the spinner.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem, we have that the first sector can be painted in any of the 4 colors, the others until the 5th can be painted in 3 colors(not the adjacent), and the sixth in only 2, as it is adjacent to both the 5th and the 1st sectors, hence:
[tex]n_1 = 4, n_2 = n_3 = n_4 = n_5 = 3, n_6 = 2[/tex]
Hence the number of ways is given by:
N = 4 x 3 x 3 x 3 x 3 x 2 = 648.

Simplify. ( 2 questions )
Answer:
7) y⁹
9) a⁸
Step-by-step explanation:
when we multiply two exponents (of the same base), we can add them
so, a² · a³ = a² ⁺ ³ = a⁵
let's test it out!
(a = 2 in our example)
2² · 2³ = 2⁵
4 · 8 = 32 (2⁵ = 32)
32 = 32
because this is true, we know that we can add exponents of the same base when multiplying them together
now, let's try out the question at hand:
y³ · y⁶
well, we know that 3 + 6 = 9, so y³ · y⁶ can be simplified to y⁹
--
now, we're going to be working with division. We know that division is the inverse of multiplication, so we logically know that instead of adding exponents, we subtract them when dividing
here,
a³ ÷ a² would equal a¹ (3 - 2 = 1)
let's put a = 2 again:
a³ ÷ a² = a³ ⁻ ² = a¹ = a
2³ ÷ 2² = 2¹
8 ÷ 4 = 2
2 = 2
once again, we have proven this shortcut to be true
now, to the problem at hand!
first, we can multiply a³ · a⁹
a³ · a⁹ = a³ ⁺ ⁹ = a¹²
so, let's rewrite the problem:
a¹² / a⁴
because we're dividing with exponents, we can subtract 12 - 4
a¹² / a⁴
a¹² ÷ a⁴
a¹² ⁻ ⁴
a⁸
so, our simplified answer is a⁸
(note: they must be the same base, [the thing that the exponent is attached to] for this to apply)

1 ) [tex]y^3* y^6[/tex]

since the base of the exponents is the same so the powers of y get added

2 ) [tex]\frac{a^3*a^9}{a^4}[/tex]

Answer:
When the volume of a gas in a container varies inversely with the pressure on the gas and a container of nitrogen has a volume of 29.5 litres with 2000 psi. So, if the tank has a 14.7 psi pressure, then the volume of the tank would be 4013.6 litres.
Step-by-step explanation:
The volume of a gas in a container varies inversely with the pressure on the gas. If a container of nitrogen has a volume of litres with psi, what is the volume if the tank has a psi pressure.Calculate the volume to the nearest whole number.Use the given values and calculate the proportionality constant as well as required solution.Step 1 of 2
Write the inversely proportionality relation between the volume and pressure of a gas in container.

Using Sarai’s measurements, Line 3 must be parallel to Line 5 according to which postulate or theorem?
I need help ASAP please!!
Using Sarai's measurements, Line 3 must be parallel to Line 5 according to (A) Converse of Alternate Exterior Angles Theorem.
Alternate Exterior Angles theorem states that, "If two lines are parallel and they are intersected by same straight line then the alternative exterior angles formed by the figure are equal to each other."
Converse of the above theorem states that, "If two lines intersected by one transverse and formed alternate exterior angles, and if they are equal to each other then that two lines are parallel to each other."
Here in Sarai's measurement we can see that Line 3 and Line 5 are intersected by one straight line and the formed alternate exterior angles both are 65, which shows they are equal to each other.
Hence by Converse of Alternate Exterior Theorem we can say that Line 3 and Line 5 are parallel to each other.
So, Line 3 must be parallel to Line 5 according to Converse of Alternate Exterior Angles Theorem.
