Answer:

80%

Step-by-step explanation:

Since we're excluding hydrogen and helium, we are looking for the % of nitrogen and oxygen.

From the graph, we can see that we found 75% oxygen (blue).

We can also see that of nitrogen, green, we found 5%.

We simply need to add these two together.

75% + 5% = 80%

j = 59

Step-by-step explanation:

since you are solving for j, you want to get it by itself

you can start out by multiplying both sides of the equation by 6 to get rid of the fractions

[tex](6)(\frac{j}{6}-9)=\frac{5}{6}(6)[/tex]

distribute the 6

[tex]j-54=5[/tex]

add 54 to both sides

[tex]j-54+54=5+54[/tex]

Answer:

w = -(5 u)/7

Step-by-step explanation:

Solve for w:

-w - 4 u = 6 w + u

Hint: | Isolate w to the left-hand side.

Subtract 6 w - 4 u from both sides:

-7 w = 5 u

Hint: | Solve for w.

Divide both sides by -7:

Answer:

the answe is -4

Step-by-step explanation:

first you distribute the five to the numbers in the paranthesis

5(-2n+6)

-10n+30=70.

than we subtract 30 from the 30 and 70

-10n=40

Next we divide by 10 to 40 and -10n

n=-4

the reason it negative is because if you divide a negative and a positive it always make a negative.

Answer: vertical translation

Step-by-step explanation:

A function is even if:

f(x) = f(-x)

and a function is odd if:

f(-x) = -f(x).

Now, we want to find a translation that only affects the symmetry of an odd function (but not that one of the even function).

The correct answer will be a vertical translation, now let's prove it.

when we have a function f(x) and we want to transform it into g(x), such that g(x) is a vertical translation of (for example) A units up, we can write the relation as:

g(x) = f(x) + A.

Now, let's see if this preserves the symmetry of the original function.

1) if f(x) is even, then:

g(x) = f(x) + A

g(-x) = f(-x) + A

But we know that f(-x) = f(x)

then:

g(-x) = f(-x) + A = f(x) + A = g(x)

this means that g(x) is even, the symmetry of an even function is not affected by this transformation.

Now suppose that f(x) is odd.

Then:

g(x) = f(x) + A

g(-x) = f(-x) + A

and f(-x) = -f(x)

then:

g(-x) = f(-x) + A = -f(x) + A

and this is clearly different than g(x) = f(x) + A.

Then the odd symmetry is broken.

BCD

Step-by-step explanation:

The top rectangle is ABCD because of its vertices.  BCD is included in it.

The top plane represented by the BCD

In geometry, a plane is a flat surface that extends into infinity. It is also known as a two-dimensional surface. A plane has zero thickness, zero curvature, infinite width, and infinite length. It is actually difficult to imagine a plane in real life; all the flat surfaces of a cube or cuboid, flat surface of paper are all real examples of a geometric plane. We can see an example of a plane in which the position of any given point on the plane is determined using an ordered pair of numbers or coordinates. The coordinates show the correct location of the points on the plane.

As, per the figure we can say that the upper plane is made of plane ABCD.

So, among all the option BCD will be correct because BCD is part of ABCD.

Answer: B: 4

Step-by-step explanation: just took the test

The seventh line will be having 4 marbles which can be determined by taking the given data as an arithmetic progression with the first term as 1 and the common difference -1. Hence, option B is the right choice.

An arithmetic progression (A.P.) is a series where every term is the sum of the previous term and a common difference.

The first term of an arithmetic progression is denoted by a, and its common difference is denoted by d. The n-th term of an arithmetic progression can be found using the formula

n-th term = a + (n-1)d.

We are given a pattern, starting with 10 marbles and every consecutive line has 1 less marble than the previous line. We are asked to find the number of marbles in the 7th line.

This can be seen as an arithmetic progression with the first term a = 10, and the common difference d = -1.

We are asked to find the number of marbles in the 7th line. This can be taken as the 7th term of the given arithmetic progression.

n-th term = a + (n-1)d

or, 7th term = 10 + (7-1)(-1) = 10 + 6(-1) = 10 - 6 = 4.

∴ The seventh line will be having 4 marbles which can be determined by taking the given data as an arithmetic progression with the first term as 1 and the common difference -1. Hence, option B is the right choice.

Answer:

7x^2 −12x−10

Step-by-step explanation:

 ((5x2 -  8x) +  1) +  (2x2 - 4x - 11)

Factoring  7x2-12x-10

The first term is,  7x2  its coefficient is  7 .

The middle term is,  -12x  its coefficient is  -12 .

The last term, "the constant", is  -10

Step-1 : Multiply the coefficient of the first term by the constant   7 • -10 = -70

Step-2 : Find two factors of  -70  whose sum equals the coefficient of the middle term, which is   -12 .

     -70    +    1    =    -69

     -35    +    2    =    -33

     -14    +    5    =    -9

     -10    +    7    =    -3

     -7    +    10    =    3

     -5    +    14    =    9

     -2    +    35    =    33

     -1    +    70    =    69

Step-by-step explanation:

Everything looks great. The only issue I see is that 27 is a bit smudged. I think you were trying to say "A, B and E" (in any order you want). If so then that would be the correct answer.

The square root of the number is A = 1/6 = 0.16667

Given data ,

Let the first number be represented as p

where the value of p = 1/36

Now , the square root of the number is expressed as

A = √p

The radical form of a number refers to expressing a number using a radical symbol (√) to represent a root.

It is used to express the roots present in the number.

So , A = √( 1/36 )

On simplifying , we get

A = 1/6

On further simplification , we get

A = 0.166667

Hence , the square root is A = 1/6 = 0.16667

Answer:

k = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 5 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus the 2 points have a slope of - 3

calculate the slope using the slope formula and equate to - 3

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (k, 5)

m = [tex]\frac{5+1}{k-4}[/tex] = [tex]\frac{6}{k-4}[/tex] = - 3 ( multiply both sides by (k - 4) )

- 3(k - 4) = 6 ( divide both sides by - 3 )

k - 4 = - 2 ( add 4 to both sides )

The equal number of signatures Mimi and Rita eventually collects are 70 signatures

Step-by-step explanation:

1) The initial number of signatures Mimi has = 30 Signatures

The average rate at which Mimi can collect signatures = 8 signatures per hour

The average rate at which Rita can collect signatures = 14 signatures per hour

The table of values showing the number of signatures Mimi and Rita can have at a given hour is presented as follows;

For Mimi, we have;

Hour        [tex]{}[/tex]    Number of Signatures

0         [tex]{}[/tex]           30

1         [tex]{}[/tex]            38

4         [tex]{}[/tex]           62

5         [tex]{}[/tex]           70

For Rita, we have;

Hour        [tex]{}[/tex]    Number of Signatures

0         [tex]{}[/tex]           0

1         [tex]{}[/tex]            14

4         [tex]{}[/tex]           56

5         [tex]{}[/tex]           70

2) The equation representing the number of signatures Mimi has at a given time, t, is given as follows;

The number of signatures Mimi has = 30 + 8 × t

The equation representing the number of signatures Rita has at a given time, t, is given as follows;

The number of signatures Rita has = 14 × t

3) Please find attached the required graph of the number of signatures Mimi and Rita has

4) The solution if the system of equations is given as follows;

30 + 8 × t = 14 × t

From which we have;

30 = 14 × t - 8 × t  = 6 × t

t = 30/6 = 5 Hours

By substituting t = 5 hours in the above equations, the equal number of signature of signatures Mimi and Rita can have is therefore;

30 + 8 × 5 = 70 signatures = (14 × 5) signatures

The equal number of signatures Mimi and Rita eventually collects are 70 signatures

5) The meaning of the solution is that is Mimi and Rita continue collecting signatures at their respective constant rate of 8 and 14 signatures per hour, given that Mimi already has 30 signatures, they will have the same number of 70 signatures after 5 hours
