Answer:
short story has 32 pgs
novel has 416 pgs
Step-by-step explanation:
a novel (N) has 13 times as many pages as a short story (x) so, N = 13X
total pages is the equation N + x = 448
plug the equation for N into this
13x + x = 448, combine like terms
14x = 448, divide both sides by 14
x = 32. so now we know that the short story has 32 pages. subtract that from 448. and the novel has 416 pages.
There are 32 pages in the short story and 416 pages in the novel.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
Let x be the number of pages in the short story.
We know that the novel has 13 times as many pages as the short story, so the number of pages in the novel is 13x.
The combined number of pages in the books is the sum of the number of pages in the short story and the number of pages in the novel, which is x + 13x = 14x = 448 pages.
So the number of pages in the short story is x = 32 pages.
And the number of pages in the novel is 13x = 13 × 32 = 416 pages.

x=3m/2-m
make m the subject of the formula
help me plss
Answer:
2X/(3+X)
Step-by-step explanation:
X = 3m/2-m
Cross multiply both sides
X × (2-m)= 3m
2X-Xm= 3m
2X= 3m+Xm
2X= m(3+X)
Divide both sides by the coefficient of m which is (3+X)
m= 2X/(3+X)
Changing the subject of a formula involves rearranging the formula
m as the subject of the formula is: [tex]\mathbf{m = \frac{2x}{3 + x}}[/tex]
The equation is given as:
[tex]\mathbf{x = \frac{3m}{2-m}}[/tex]
Cross multiply
[tex]\mathbf{x(2-m) = 3m}[/tex]
Open brackets
[tex]\mathbf{2x-mx = 3m}[/tex]
Collect like terms
[tex]\mathbf{2x= 3m +mx}[/tex]
Factor out m
[tex]\mathbf{2x= m(3 +x)}[/tex]
Divide both sides by 3 + x
[tex]\mathbf{\frac{2x}{3 + x}= m}[/tex]
Rewrite the above equation as:
[tex]\mathbf{m = \frac{2x}{3 + x}}[/tex]
Hence, m as the subject of the formula is:
[tex]\mathbf{m = \frac{2x}{3 + x}}[/tex]

What is the rate of change in y per unit change in x for the function 30x + 5y = 15?
Answer:
to find the answer you have to put it into y=mx+b format.
This means that it will be 5y=-30x+15
So it will simplify to y=-6x+3
This means that:
If y=2
You substitute then…
2=-6x+3
So x would equal 1/6.
Step-by-step explanation:
The rate of change is -1/6.
What is rate of change?Rate of change (ROC) refers to how quickly something changes over time. It is thus the acceleration or deceleration of changes (i.e., the rate) and not the magnitude of individual changes themselves. In finance, rate of change is used to understand price returns and identify momentum in trends.
The units on a rate of change are “output units per input units.” The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
Given:
30x + 5y = 15
We know that the equation of line y= mx + b
Now, using 30x + 5y = 15
5y=-30x+15
Dividing both side by 5.
y = -30x/5 + 15/5
y = -6x + 3
let us take y= 4
4 = -6x + 3
1 = -6x
x= -1/6

If there is a very weak correlation between two variables, then the coefficient of determination must be:__________.
Answer:
zero
Step-by-step explanation:
The coefficient of determination (R², or the square of the linear correlation coefficient r) is an indicator that allows us to judge a simple linear regression quality. It measures the fit between the model and the observed data or how well the regression equation is suited to describe the distribution of points.
A strong correlation between two variables is usually greater than 0.8. A weak correlation between two variables is usually less than 0.5, but a very weak correlation between two variables will be near zero.

Using π = 3.14, find the area of a circle with a radius of 7. Round your answer to the nearest hundredth
Answer:
The formula for calculating the circumference (C) of a circle, C = πD or C = 2πR, is simple if you know the circle's diameter (D) or radius (R). But what do you do if you only know the circle's area? Like many things in math, there are multiple solutions to this problem. The formula C = 2√πA is designed to find a circle's circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result.
