Emma types one-third of a paper for History class in 34 hour. What part of the paper can she type in one hour?

Answer:

C

Step-by-step explanation:

The x is 3 and the y is 1 so if you divide the x by 3 it is 1 which is the y.

The relationships which have the same constant of proportionality between y and x as in the equation y = 1/3x are C and E.

The slope of a line is the ratio that determines the steepness as well as the direction of the line.

Let the two points on a line be [tex](x_{1} , y_{1} )[/tex] and [tex](x_{2} , y_{2 )[/tex]. The slope can be found as follows:

[tex]\frac{(y_{2} -y_{1} )}{(x_{2} -x_{1} )}[/tex]

The constant of proportionality in the given problem can be understood as the slope of the line. Thus the lines with their slopes as 1/3 will have the same constant of proportionality as the equation y = 1/3 x.

We can observe the graphs given and find their respective slopes. It can be done as follows:

(3 - 0)/(0 + 3) = 1

(3 - 0)/(1 - 0) = 3

(1 - 0)/(3 - 0) = 1/3

(29.1 - 4.8)/(9.7 - 1..6) = 3.111

(0.8 - 0.5)/(2.4 - 1.5) = 1/3

Therefore, graphs C and E have relationships that have the same constant of proportionality between y and x as in the equation y = 1/3 x.

Answer:

1. 2

2. 30

Step-by-step explanation:

1. The weird circle looking thing essentially means you're putting p(x) inside of q(x). This means you take the x in q(x) and replacing with the entire p(x)

so q(x) = -3x - 4

(q °p)(x) = -3 (-2x+4) -4  sorry I can't find the actual circle thing symbol

now distribute to get the simplified equation:

= 6x -12 -4

= 6x - 16

because you're doing (q - p )(3), you would plug 3 for x into the new equation

6(3) - 16 = 2

and thats you're answer for the first one

for the second one its the other way around, so you're putting all of q(x) into p(x)

take p(x) : -2x+4

and now replace the x with the entire q(x)

so (p - q)(x) = -2 (-3x-4) +4

simplify: = 6x+8+4 = 6x+12

so now since we're doing (p-q)(3), we need to plug in 3 for x in the new equation

= 6(3)+12 = 30

lmk if those were wrong or if my explanation was unclear, there's another way I can explain it even though its the same process :)

Answer:

k = -13

Step-by-step explanation:

-4(k +2) = -k +31

you multiply the bracket by -4

-4k-8 = -k+31

Collect the like terms

-4k+k = 31+8

-3k =39

divide both sides by -3

k = -13

Answer:

k = -13

Step-by-step explanation:

Distributive property

(-4 x k + -4 x 2)

-4k + -8 = -k + 31

subtract 31 from both sides.

-4k - 39 = -k

add 4k to both sides

-39 = 3k

divide 3 from both sides

-13 = k

Answer:

180mm^2

Step-by-step explanation:

CB = 15^2 + 6^2 = 261, the square root of 261 is ~16mm

CB is 16mm

the area of the triangle is A=ab/2

A=45mm^2

Now you need to find the area of the rectangle

A=l×w

A= 15×9= 135mm^2

now add both areas

(135+45)mm^2=180mm^2

The solution is : 6 feet describes the center, and 9 feet describes the spread

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

here, we have,

The center of a data set is mostly considered as the median or the mean

Here mean is 6 (given). And median is also 6.

As 6 is exactly at the middle of the data set. (When arranged in ascending order)

Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.

Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.
