Answer:

53712.4

Step-by-step explanation:

[tex]53.7124 * 10^{3}[/tex] This is the scientific notation, and since we do not have a negative exponent, we can assume that the decimal is going to move to the right, because when it's negative, the decimal will move to the left, making a smaller number.

So, when we move the decimal 3 times to the right, we find it sitting at 53712.4

Answer:

1) 21

2a) -23/30

2b) 6/55

Step-by-step explanation:

1) 3(x + 2) + 5x + 7

expand the brackets:

= 3x + 6 + 5x + 7

collect like terms:

= 8x + 13

when x = 1, (just substitute 1 for x)

8(1) + 13

= 8 + 13

= 21

2a)

-9/10 + 2/15

put both fractions on the same denominator (often we can just multiply each denominator by the other one):

so -9/10 * 15/15

= -135/150

and 2/15 * 10/10

= 20/150

now they're both on the same denominator and we can add the numerators:

-135 + 20 = -115

so our answer is:

-115/150

which we can simplify to:

-23/30

2b)

3/11*2/5

Multiplying fractions is very simple, as it doesn't require to have the same denominators. We can just multiply the numerators by each other and same for the denominators:

3*2 = 6

11*5 = 55

therefore, our answer is:

6/55

A)

3(x+2) + 5x + 7

3x + 6 + 5x + 7

3x + 5x + 6 + 7

put x = 1

3(1) + 5(1) + 6 + 7

3 + 5 + 6 + 7

21

B)

a)

[tex]\sf \rightarrow -\dfrac{9}{10} + \dfrac{2}{15}[/tex]

[tex]\sf \rightarrow -\dfrac{9(15)}{150} + \dfrac{2(10)}{150}[/tex]

[tex]\sf \rightarrow -\dfrac{135}{150} + \dfrac{20}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-135+20}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-115}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-23}{30}[/tex]

b)

[tex]\sf \rightarrow \dfrac{3}{11} \ * \ \dfrac{2}{5}[/tex]

[tex]\sf \rightarrow \dfrac{3*2}{11 *5}[/tex]

[tex]\sf \rightarrow \dfrac{6}{55}[/tex]

Answer:

D None of these choices are correct.

Step-by-step explanation:

The value of x is 27.

[tex]\frac{x}{9} = \frac{9}{3}[/tex], x = 9 x [tex]\frac{9}{3}[/tex] = 27

Answer:

-6x

Step-by-step explanation:

This is correct because an unknown product is always classified as a variable or a most common used one, X. The product of -6 with an uknown variable, also known as a number, is -6x. Hope this helped and have a Great Day!!!

Answer:

A. f = 400 + 50d

Step-by-step explanation:

First, let's understand each quantity/variable.

Now that we understand these variables, we can conclude that the equation would be A. f = 400 + 50d because to find the total, we have to add the 400 eyeliners sold at the beginning to the 50 eyeliner sales per day.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:

B. SSA

Step-by-step explanation:

Because we have 2 sides with a non-included (not in-between the two sides) angle, the triangles are similar by SSA Similarity.

Answer:

2.25

Step-by-step explanation:

Notice how the common ratio is -1/3, which means the series passes part 1 of the convergence test because -1/3 is in between -1 and 1.

We can also represent this as a summation series of

[tex]Σ3( - \frac{1}{3} ) {}^{n - 1} [/tex]

Since we can represent this a summation series, we can use that convergent value is equal to

[tex] \frac{a _{1} }{1 - r} [/tex]

where a1 is initial term and r is common ratio.

R is -1/3

A1 is 3.

[tex] \frac{3}{1 - \frac{ - 1}{3} } = \frac{3}{ \frac{4}{3} } = 2.25[/tex]

So the answer is 2.25

Answer:

I believe it is the top right scatterplot, I can't tell which letter, I think B though.

Step-by-step explanation:

If you were to put a line of best fit for each graph, the top right scatterplot would be the only one that has a straight line of best fit.

Hope this helps :)

Answer:

Graph B

Step-by-step explanation:

Because it asked for a LINEAR relationship, and Graph B is the closest graph for a LINEAR relationship.

Hope it helps bro.

Answer:

supplementary

Step-by-step explanation:

we have,

3x+15+2x=180

=> 5x +15 = 180

=> 5x = 180-15

=> 5x = 165

=> x = 165/5

=> x= 33

so, 3x+15 = 3*33+15

=> 99+15

=>114

2x = 2*33

=> 99

now we can check if these angles are supplementary

114 + 99 = 180

so, they are supplementary

Answer:

D. Undefined term

Step-by-step explanation:

Points are flat surfaces, named using a capital letter, and have no depth or width because they are on a FLAT plane. Just like lines are named "line A", are on a flat surface, and have no depth or width, points also share these characteristics because they are all on a plane. However, a point is not an undefined term, it is a defined term.

A point is a geometric feature used for the definition of geometric objects

The option which is not a characteristic of a point is option A:

A. Flat surface

The reason for the above selection is as follows:

A point in Euclidean geometry is a concept that defines an exact spatial location

The characteristics of a point are:

A flat surface is defined by three noncolinear points

Therefore;

The given option which is not a characteristic of a point is therefore option A. Flat surface

Answer:

Step-by-step explanation:

We are looking for a fraction with the numerator f and denominator g + 11.

This is:

[tex]\qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}x~\hfill } \\\\ \textit{\underline{x} varies directly with }\underline{z^5}\qquad \qquad \stackrel{\textit{constant of variation}}{x=\stackrel{\downarrow }{k}z^5~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}[/tex]

[tex]\stackrel{\textit{"y" varies directly with "x"}}{y=kx}\qquad \qquad \textit{we also know that} \begin{cases} y=-8\\ x = 4 \end{cases}\implies -8=k(4) \\\\\\ \cfrac{-8}{4}=k\implies -2=k ~\hfill therefore~\hspace{10em}\boxed{y=-2x} \\\\\\ \textit{when x = -4 what is "y"?}\qquad y=-2(-4)\implies y=8[/tex]

Answer:

y=8

I didn't need a equation if they vary directly with each other then if the sign switches from 4 to -4 then -8 must have switched to 8
