Savannah uses 3.5 ounces of window cleaner on each window, She cleans more than 18 windows. Write an inequality that can be used to determine how much window cleaner Savannah uses.

The amount of peanuts Maggie puts in each container is 1/9 pounds per container.

Number of pounds of peanut Maggie has = 2/3 pounds

Number of containers = 6

Number of peanuts in each container = Number of pounds of peanut Maggie has / Number of containers

= 2/3 ÷ 6

multiply by the reciprocal of 6

= 2/3 × 1/6

= 2/18

= 1/9 pounds per container

Hence, there are 1/9 pounds of peanuts in each container if Maggie puts an equal amount.

If there were 18 students in each group and they were asked to form six equal groups, then there would be a total of 108 students.

i.e. (18 students x 6 groups = 108 students)

When a group of students are asked to form a certain number of equal groups, the total number of students can be determined by multiplying the number of students in each group by the number of groups.

In this case, the students were asked to form six equal groups and there were 18 students in each group.

To find the total number of students, we simply multiply 18 by 6.

Therefore, there were 108 students in total.

This is because when you have x number of groups and y number of students in each group, the total number of students is xy.

In this case x=6 and y=18, so the total number of students is 6*18 = 108.

Answer: 2:7

Step-by-step explanation:

Vanilla icecream = 4

Chocolate icecream = 14

4:14=2:7

2X2=4

7X2=14

Step-by-step explanation:

a ratio is simply relating 2 (or more) groups and their sizes.

in our case here the ratio is

4/14 = 2/7

this is often written as

4:14 = 2:7

it means that for every 2 people liking (I assume "preferring") vanilla ice cream there are 7 people liking (preferring) chocolate ice cream.

FYI

in total, a ratio also tells us about the size of the sample for the observation or analysis. 4/14 tells us there are 18 (4+14) people in the survey. and the simplified form 2/7 tells us that we can split the whole survey group into units of 9 (2+7) people with the same behavior as the total group.

a ratio is a fraction (incl. all the calculation and comparison rules) with a special meaning.

so, don't mix the ratio up with e.g. the fractions of the different behaviors in the group :

4/18 = 2/9 of the whole group prefer vanilla.

14/18 = 7/9 of the whole group prefer chocolate.

the ratio is now the relative size relationship between both : 2/9 / 7/9 = 2/7

Step-by-step explanation:

The two quadrilaterals are similar to each other. So the ratio of  each side of the larger quadrilateral to the corresponding side of the smaller quadrilateral must be the same.

Examining the two figures we see the side which has  68° and 128° pf the smaller quadrilateral has length 2

The corresponding side of the larger quadrilateral on the right is 6

So each side of the larger quadrilateral =6/2 = 3 times each side of the smaller one

Side which has length 10 pf the smaller quadrilateral corresponds to the side with length x+10 of the larger one. This ratio must also be 1:3

So

[tex]\dfrac{10 + x}{10}= 3\\\\[/tex]

Cross-multiplying we get
10 + x = 10 x 3

10 + x = 30

x = 30-10

x =20

ANSWER

The axis of symmetry is the line x=3.

As y  is a linear term and x is quadratic, this means we’re dealing with either an ‘n-shaped’ parabola or a ‘u-shaped’ parabola.

As the coefficients of  x² and y have the same sign they’re both positive, which means we have a ‘u-shaped’ parabola.

One can express a parabola in the vertex form,  y=a(x−p)²+q, which tells us that the vertex is the point  (p,q)  and the axis of symmetry is the line x=p.

So, let’s apply this format to your parabola.

y=(x−3)²=(x−3)²+0

From this, it’s clear that:

The vertex is the point (3,0)

To calculate the composition of two functions, "F" and "G", represented by the notation "FG", you first need to have a specific input value, usually represented as "x".The first step is to apply the function "G" to the input "x", resulting in G(x).

The next step is to take the output of the function G, which is G(x), and use it as the input for the function F.

The final step is to apply the function F to the output of G(x) resulting in F(G(x)), which is the composition of the two functions F and G.

In other words, you apply the function G to the input x, and then you apply the function F to the result of G(x). The final result is the function F(G(x)), which is the composition of the functions F and G.

It's important to note that the order of the functions in composition matters and can change the result of composition. The notation "FG)(x)" is different from "GF)(x)" which means that the order of the functions matter in composition.

What is ttemperature rate ?

With increase in temperature, the rate of the reaction and the rate constant increases. As a generalization, the rate of the reaction (and the rate constant) becomes almost double for every ten degree rise in temperature. This is also called temperature coefficient.

the heat Q required to raise the temperature of water varies jointly as the mass m of the water and the amount of temperature change T, and Q = 20,930 J when m = 1 kg and T = 5°C.

So, write an equation for Q as:

Q = k * m * T

where k is a constant of proportionality.

Substituting the known values, we can find k:

20930 = k * 1 * 5

k = 20930 / (1 * 5) = 4186

Now that we have k, use it to find m when Q = 8349 J and T = 3°C:

8349 = 4186 * m * 3

m = 8349 / (4186 * 3)

k = Q / (m * T) = 20,930 / (1 * 5) = 4186

Now that we have found k, we can use it to find m when Q = 8,349 J and T = 3°C:

Q = k * m * T

8,349 = 4186 * m * 3

m = 8,349 / (4186 * 3) = 8,349 / 12,558

No, the number 52 is not a perfect square. Because the square root of 52 is an irrational number.

An irrational number is a real number that cannot be expressed as a ratio of two integers, or in other words, as a fraction. Irrational numbers include numbers such as pi (π), the square root of 2, and the square root of 3, which are not terminating or repeating decimals. They cannot be written as a finite decimal or a fraction of integers. Irrational numbers have an infinite number of decimal places, which means they cannot be represented exactly as a decimal.

They are also non-repeating and non-terminating decimals. Irrational numbers have many important properties and applications in mathematics, such as in geometry, where they are used to calculate the lengths of curves and the areas of circles. They also appear in trigonometry and calculus. Irrational numbers are also important in physics and engineering as well as other branches of science and technology.

Answer:

x = 7 , VS = 6

Step-by-step explanation:

• If two chords of a circle are equidistant from the centre of the circle then they are congruent.

given ZU and ZV = 5

then the chords QR and ST are equidistant from the centre and are congruent , that is

QR = ST

2x - 2 = 12 ( add 2 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

The tallest lighthouse in the world is the Jeddah Light. It is 133 m tall. A dhow is sailing away from this lighthouse. From the top of the lighthouse, the angle of depression to the dhow is 65° Later, the angle of depression has changed to 40°.

How far did the dhow travel during that time?

To solve this problem, we can use trigonometry and the fact that the angles in a triangle add up to 180°.

Let's call the distance between the lighthouse and the dhow "d".

We know that the angle of depression from the top of the lighthouse to the dhow is 65°, and the angle of depression later changed to 40°.

Let's call the angle between the horizontal and the line of sight from the lighthouse to the dhow, "x"

Since the angles in a triangle add up to 180°, we can say that:

x + 65 + 40 = 180

x = 75

Now, we can use the tangent function to find the distance d. We know that:

tan(x) = d / h

tan(75) = d / 133

d = 133 * tan(75)

Therefore, the dhow traveled 133 * tan(75) distance during that time.

To solve for g in terms of T, L, we can manipulate the formula T = 2π √(L/g) as follows:

First, we divide both sides by 2π:

T/2π = √(L/g)

Then, we square both sides:

(T/2π)² = (L/g)

Then, we multiply both sides by g^2 :

(T^2/4π^2) = L

Finally, we divide both sides by L:

(T^2/4π^2 * L) = g

So the formula for g in terms of T, L is g = (T^2/4π^2 * L)

Please note that this formula is only valid for simple pendulum and not for any complex pendulum, and also the result is in terms of acceleration due to gravity g.

The polynomial function with zeroes at -2, 0, and 3√2 is (x+2)(x-0)(x-3√2) = [tex](x+2)*(x-3\sqrt{2}) = x^3 - 3x\sqrt{2x} - 2x^2.[/tex]

The polynomial function with zeroes at -1, 3, and 2i is (x+1)(x-3)(x-2i) = [tex](x+1)(x-3)(x^2+4) = x^3 +x^2 - 11x -12[/tex]

A polynomial function is a function of the form f(x) = a_nx^n + a_{n-1}x^{n-1} + ... + a_1x + a_0, where n is the degree of the polynomial and the a_i are constants. To find a polynomial function with zeroes at -2, 0, and 3√2, we can use the fact that if a polynomial function has a zero at x=c, then (x-c) is a factor of the polynomial. Therefore, we can write the polynomial function as [tex](x+2)(x-0)(x-3\sqrt{2}) = (x+2)x(x-3√2) = x^3 - 3x\sqrt{2x} - 2x^2[/tex].

In this case, we can see that x = -2, x = 0, x = 3√2 are the zeroes, so we know that (x+2), x and (x-3√2) are the factors of the polynomial.

Similarly, to find a polynomial function with zeroes at -1, 3, and 2i, we can use the fact that if a polynomial function has a zero at x=c, then (x-c) is a factor of the polynomial. Therefore, we can write the polynomial function as [tex](x+1)(x-3)(x-2i) = (x+1)(x-3)(x^2+4) = x^3 +x^2 - 11x -12[/tex]

In this case, we can see that x = -1, x = 3, x = 2i are the zeroes, so we know that [tex](x+1), (x-3), (x^2+4)[/tex]are the factors of the polynomial.

It is worth noting that (x-2i) is a zero of the polynomial, so (x-2i)(x+2i) = [tex]x^2[/tex]+4 is a factor of the polynomial and it is included in the polynomial..
