The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days. Which ratio shows the number of chlorine tablets needed for 42 days? A. 14 to 42 B. 15 to 42 C. 19 to 42 D. 3 to 42
Answer: B (15 to 42)
Step-by-step explanation:
In order to get from 14 to 42, you must multiply by 3 (42/14 = 3). So to get an equivalent ratio, you must also multiply 5 by 3.
5:14 = 5*3:14*3 = 15:42 (B).
Answer:
15 to 42.-B
Step-by-step explanation:
5 tablets for every 14 days
X3
15 tablets every 42 days
The graph below shows the distance in miles, m, hiked from a camp in h hours.
Which hourly interval had the greatest rate of change?
1) hour 0 to hour 1
3) hour 2 to hour 3
2) hour 1 to hour 2
4) hour 3 to hour 4
Answer:
Option 1) is correct
Step-by-step explanation:
Given: The graph shows the distance in miles, m, hiked from a camp in h hours.
To find: hourly interval that had the greatest rate of change
Solution:
Rate of change between two points refers to the vertical change divided by the horizontal change.
For hour 0 to hour 1:
rate of change = [tex]\frac{2-0}{1-0}=2[/tex]
For hour 2 to hour 3:
rate of change = [tex]\frac{4.5-3.5}{3-2}=1[/tex]
For hour 1 to hour 2:
rate of change = [tex]\frac{3.5-2}{2-1}=1.5[/tex]
For hour 3 to hour 4:
rate of change = [tex]\frac{5-4.5}{4-3}=0.5[/tex]
So, rate of change is greatest in interval: hour 0 to hour 1
The greatest rate of change between the interval 0 to 1 hour.
Given that,
The graph below shows the distance in miles, m, hiked from a camp in h hours.
We have to determine,
Which hourly interval had the greatest rate of change?
According to the question,
The greatest rate of change between the interval is determined by the rate of change between two points refers to the vertical change divided by the horizontal change.
1. The rate of change between 0 to 1 hours is,
[tex]\rm Rate \ of \ change = \dfrac{2-0}{1-0}\\\\ Rate \ of \ change= \dfrac{2}{1}\\\\ Rate \ of \ change= 2[/tex]
The rate of change between 0 to 1 hour is 2.
2. The rate of change between 2 to 3 hours is,
[tex]\rm Rate \ of \ change = \dfrac{4.5-3.5}{3-2}\\\\ Rate \ of \ change= \dfrac{1}{1}\\\\ Rate \ of \ change= 1[/tex]
The rate of change between 2 to 3 hours is 1.
3. The rate of change between 1 to 2 hours is,
[tex]\rm Rate \ of \ change = \dfrac{3.5-2}{2-1}\\\\ Rate \ of \ change= \dfrac{1.5}{1}\\\\ Rate \ of \ change= 1.5[/tex]
The rate of change between 1 to 2 hours is 1.5.
4. The rate of change between 3 to 4 hours is,
[tex]\rm Rate \ of \ change = \dfrac{5-4.5}{4-3}\\\\ Rate \ of \ change= \dfrac{0.5}{1}\\\\ Rate \ of \ change= 0.5[/tex]
The rate of change between 2 to 3 hours is 1.
Hence, The required greatest rate of change between the interval 0 to 1 hour.

The points (-11, r) and (-7,5) lie on a line with slope
3
4
Find the missing coordinate r.
Answer:
r = 2
Step-by-step explanation:
Calculate slope m using the slope formula and equate to [tex]\frac{3}{4}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 11, r) and (x₂, y₂ ) = (- 7, 5)
m = [tex]\frac{5-r}{-7+11}[/tex] = [tex]\frac{5-r}{4}[/tex] = [tex]\frac{3}{4}[/tex] ( multiply both sides by 4 to clear the fractions )
5 - r = 3 ( subtract 5 from both sides )
- r = - 2 ( multiply both sides by - 1 )
r = 2

Factor the quadratic expression completely: 15x^2 - 4x -4
WHY IS THIS SO HARD !!!!!
Step-by-step explanation:
We can rewrite as 15x² + 6x - 10x - 4. The first two and last two terms have common factors so this turns into 3x (5x + 2) - 2 (5x + 2). This will then become (5x + 2)(3x - 2).
Answer:
(-2 + -5x)(2 + -3x)
Simplifying
15x2 + -4x + -4
Reorder the terms:
-4 + -4x + 15x2
Factor a trinomial.
(-2 + -5x)(2 + -3x)
Final result:
(-2 + -5x)(2 + -3x)

formula for the volume of a hemisphere=2/3 x pi x r^3
The volume of a hemisphere radius of 44.9 m rounded to the nearest 10th of a cubic meter is 181,037 cubic meters.
How to calculate volume of a hemisphere?We can say that a hemisphere is exactly half of a sphere. The volume of the hemisphere is obtained by Archimedes and is half the volume of a sphere. The volume V of a hemisphere is two-thirds times pi times the radius cubed.
The formula for the volume of a hemisphere is :
[tex]V=2/3 * \pi * r^3\\V= 2/3 (3.14) (44.9)^3\\V= 181,037 m^3[/tex]

2nd month = 18[tex]\frac{3}{4}[/tex] + [tex]\frac{3}{4}[/tex] = 19[tex]\frac{1}{2}[/tex]
3rd month = 19[tex]\frac{1}{2}[/tex] + [tex]\frac{3}{4}[/tex] = 20[tex]\frac{1}{4}[/tex]
4th month = 20[tex]\frac{1}{4}[/tex] + [tex]\frac{3}{4}[/tex] = 21

Grace:
Because Anna is [tex]\frac{9}{4}[/tex] inches shorter than Grace, we can start the count from the third month:
1st month = 20[tex]\frac{1}{4}[/tex]
2nd month = 21

What is a linear equation?A linear equation has one or two variables.
No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c. When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.explanation:
-x + 2y = -8
= 2y = -8 + x
y = -8/2 + 1/2x
y = -4 +1/2x
solving this we will get the valve of Y if x is given.
