Given :
The Ironman endurance race has a 2.4 miles swim.
Javier can swim 0.5 miles in 20 minutes.
To Find :
How much time in hours it takes to complete the race.
Solution :
Speed of Javier :
[tex]s=\dfrac{2.4}{\dfrac{20}{60}}\ mph\\\\s= 7.2\ mph[/tex]
Let, time taken to cover 2.4 miles is t .
So,
[tex]t = \dfrac{2.4}{7.2}\ hours\\\\t = 0.33\ hours[/tex]
Hence, this is the required solution.

Answer:
the first one is c 2x+y=7/ the second one y=2x+7
Step-by-step explanation:
y= -2x +7 so slope good
subtract 10 for the x variable -3 so 5,-3 and your good.
use y2-y1 over x2-x1 and you find 2x and see that 0,7 is slope.

what is the value of the ratio 4:5
Answer:
You might need to be more specific, it could be 4 puppies to 5 dogs, or 4 apples to 5 oranges or 4 cups of flour to 5 cups of flour.
Step-by-step explanation:
The value of 4:5 is 4 for every 5 like 4 cups of sugar for every 5 cups of flour
The simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that the ratio is 4:5.
To convert mixed numbers into improper fractions, when A is the numerator or B is the denominator,
If either A or B is a decimal number, multiply both of their values by the same factor of 10, which will remove all decimal places.
If one value is a whole number and the other is a fraction, you should try to reduce the fraction to a whole number or convert the whole number to a fraction by giving it a denominator of 1.
= 4 / 5
We have to apply the division operation in which we have to divide the number 4 by 5 in order to obtain the improper fraction values as,
=0.8
Thus, the simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.

What is the equation of the line that passes through the point (8,4) and has a slope of 3/2 ?
Answer:
y = [tex]\frac{3}{2}[/tex] x - 8
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 )
Here m = [tex]\frac{3}{2}[/tex] , thus
y = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
To find c substitute (8, 4) into the partial equation
4 = 12 + c ⇒ c = 4 - 12 = - 8
y = [tex]\frac{3}{2}[/tex] x - 8 ← equation of line
The equation of a line that has a slope of 3/2 and passes through (8, 4) can be written as:
[tex]y - 4 = \frac{3}{2} (x - 8)[/tex] (point-slope form) or
[tex]y = \frac{3}{2}x - 8[/tex] (slope-intercept form).
Given:
a point on a line: (8, 4)
slope of the line: 3/2
The equation of the line can be written in either point-slope form or slope-intercept form.
First, let's write the equation in point-slope form since we know one of the points and the slope.
Point-slope equation takes the form: y - b = m(x - a)Where,
(8, 4) = (a, b), andm = 3/2Substitute[tex]y - 4 = \frac{3}{2} (x - 8)[/tex] =>> point-slope form.
Also, we can rewrite in slope-intercept form as follows:[tex]y - 4 = \frac{3}{2} (x - 8)[/tex]
Open bracket[tex]y - 4 = \frac{3}{2}x - 12[/tex]
Add 4 to both sides[tex]y - 4 + 4 = \frac{3}{2}x - 12 + 4\\\\y = \frac{3}{2}x - 8[/tex](slope-intercept form)
Therefore, the equation of a line that has a slope of 3/2 and passes through (8, 4) can be written as:
[tex]y - 4 = \frac{3}{2} (x - 8)[/tex] (point-slope form) or
[tex]y = \frac{3}{2}x - 8[/tex] (slope-intercept form).

0.57
0.69
Answer:
3rd choice 0.57
Step-by-step explanation:
when rounding to the tenth place we look at the hundreds place and when it greater than or at 5 we round up and when it's less than 5 we round down.
1) explanation:0.7 when rounding to the tenth place. since the 8 was greater than 5 we round-up and get 0.70.
2)explanation: 0.5 when rounded to the tenth place the hundreds place which is 2 is less the 5 so we round down and get 0.50.
3)explanation: 0.6 when rounded its hundreds place is greater than 5 so we round up and get 0.60.

Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she sees the third mile marker ,she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?
Answer:
hence, she is riding [tex]\frac{2}{15}[/tex] miles per minute
Step-by-step explanation:
The computation of the rate at which she is riding is shown below:
Given that
Rita covered 1 mile in 15 minutes.
And, her covered 3 miles in 30 minutes.
Now
Let us assume the number of miles covered would be in x minutes
So for one miles the point would be (15,1)
And for three miles, the point is (30,3)
Now the slope of the line is
m equal to
[tex]\frac{y_2 - y_1}{x_2 - x_1} \\\\\frac{3 - 1}{30 - 15} \\\\\frac{2}{15}[/tex]
hence, she is riding [tex]\frac{2}{15}[/tex] miles per minute

As per the quadratic equation, the given equation can be modified into (x - 2)² = 1. The value of x is 3, 1.
What is a quadratic equation?A quadratic equation is an equation where the variable has the highest degree of 2. A quadratic equation might have more than one variable. However, the highest degree of any variable must be 2.
Given equation: x² - 4x + 3 = 0
⇒ x² - 4x + 3 + 1 = 1 (By adding 1 on either side)
⇒ x² - 4x + 4 = 1
⇒ x² - 2 × x × 2 + 2² = 1
⇒ (x - 2)² = 1
⇒ x - 2 = ±1
⇒ x = 3, 1
