Mrs. Travis rode her bike 17.8 miles the first week, 21.5 miles the second week, and 13.4 miles the third week. The rest of her mileage was in the final week of the month. Her total mileage for the month was 62.9 miles.
She rode her bike 10.2 mile the final week.
You simply just add all of the numbers together & subtract from 62.9 then get 10.2.
Hopefully this helps! :-)

1. There are 6 girls and 7 boys in a class. A team of 10 players is to be selected from the class. How many different combinations of players are possible?
2. There are 6 girls and 7 boys in a class. A team of 10 players is to be selected from the class. If the selection is random, what is the probability of selecting a team of 5 girls and 5 boys? what is the decimal?
Answer: 1. 286 different combinations of players are possible.
2. The probability of selecting a team of 5 girls and 5 boys is [tex]\frac{63}{143}[/tex] and the decimal is 0.4405...
Step-by-step explanation:
1. Number of girls is 6 and number of boys is 7.
So, the total number of players = 6+7 = 13
A team of 10 players is to be selected from the class.
So, the total possible number of different combinations of players will be: [tex]^1^3C_{10} = \frac{13!}{10! (13-10)!}=\frac{13*12*11*10!}{10!*3!}= \frac{13*12*11}{6}=286[/tex]
2. Number of girls is 6 and number of boys is 7.
The possible number of teams by selecting 5 girls and 5 boys will be: [tex]^6C_{5}\times ^7C_{5} =6\times 21= 126[/tex]
and the number of total possible teams of 10 players [tex]= ^1^3C_{10} =286[/tex]
Thus, the probability of selecting a team of 5 girls and 5 boys [tex]=\frac{126}{286}= \frac{63}{143}[/tex] or [tex]0.4405...[/tex]

explain in words how to find the product of -4(-1.5) on the number line
Multiplying Negatives odd # of negatives means negative answer. even means positive answer.
-4(1.5) Change both to improper fractions
-4/1(6/5) Multiply
-24/5 Simplify
-4 4/5 THE END
To find the product of -4(-1.5) on the number line, start from zero, move 4 units to the left due to the negative sign, and then move 6 units (4 x 1.5) to the right because of the negative multiplied by a negative rule. The result is 6.
Explanation:To find the product of -4(-1.5) on the number line, you would follow a few steps. First, choose your starting point on the number line. In this case, the starting point would be zero.
Next, because the first number is negative, move 4 units to the left from zero. Since the second number is also negative, it changes the direction. So multiply by 1.5 in the opposite direction, which means moving to the right on the number line.
However, as it's a decimal multiplication you need to move 1.5 times or multiply the distance you moved when you moved 1 unit 4 times. It's like taking 1.5 steps to the right for each of the 4 steps we initially moved to the left. In the end, you will end up 6 units to the right of 0. Thus, the product of -4 and -1.5 is 6.

A mattress store charges 7% sales tax and a 50 delivery fee
We are given function f(a) = 1.07a for total amount including sales tax.
g(b) = b+50 total cost including delivery.
We need to write function g(f(a)).
g(f(a)) = g of f(a).
We need to substitute function f(a) in g(b) function for b.
g(f(a)) = g(1.07a) = 1.07a +50.
Therefore, g(f(a)) = 1.07a +50.We are given mattress price a = $1125.
In order to find the total cost including delivery charges, we need to plug a= 1125 in the above function 1.07a +50.
Plugging a= $1125, we get
g(1125) = 1.07a +50 = 1.07*1125 +50 = 1203.75 +50 = 1253.75.
Therefore, total cost including delivery charges is $1253.75.Answer:
g(f(a)) = 1.07a +50.
Total cost including delivery charges is $1253.75.

Sarah owns a car that runs on a mixture of gasoline and ethanol. She can buy fuels that have 85% ethanol or 25% ethanol. How much of each type of fuel should she buy if she wants to fill her 20 gallon tank with a mixture of fuel that contains 50% ethanol?
Denise needs to buy 25/3 gallons of 85% ethanol and 35/3 gallons of 25% ethanol to have 20 gallons of 50% ethanol.
x | y | 20 gal
use x and y because you don't know how much she needs.
0.85x | 0.25y | 20(0.5)
85% is 85/100 or 0.85, and you need that much of x, same goes for the 25% and 50% mixtures
so now you can make up 2 equations
1) x + y = 20
2) 0.85x + 0.25y= 10 (you get 10 when you multiply 20 by 0.5)
now you can solve for x or y using substitution. first rewrite 1) in terms of x or y:
x+ y= 20 ----> y= 20 - x
now you can substitute 20- x for y in the second equation..
0.85x + 0.25y= 10
0.85x + 0.25(20-x)= 10 distribute here..(0.25 * 20 and 0.25 * (-x) )
0.85x + 5 - 0.25x = 10 combine like terms
0.6x +5 = 10 move the 5 over to the other side
0.6x= 10 -5
0.6x = 5 divide both sides by 0.6
x= 25/3 or 8.3 now you know the amount of x so you can substitue this back into the first equation to find y.
0.85x + 0.25y= 10
0.85(25/3) +0.25y= 10
85/12 + 0.25y= 10
0.25y = 10- 85/12
0.25y= 35/12
y= 35/3 or 11.6
you can check by putting these values into the euations:
1) x+ y= 20
25/3 + 35/3 =20
20= 20 good so far
2) 0.85x + 0.25y= 10
0.85(25/3) + 0.25(35/3)=10
10 = 10 so our values for x and y work
What is 0.8 divided by 0.6 and what would it be if I round it to the nearest hundred
Final answer:
0.8 divided by 0.6 is 1.33333... which, when rounded to the nearest hundredth, is 1.33. The rounding should be done to the nearest hundredth as 'rounding to the nearest hundred' typically does not apply to decimals.
Explanation:
To calculate 0.8 divided by 0.6, we simply perform the division:
0.8 ÷ 0.6 = 1.33333...
When we round this to the nearest hundredth, we look at the third decimal place. Since it's 3, we do not round up the second decimal place. Thus, 1.33333... rounded to the nearest hundredth is 1.33.
Rounding numbers and understanding division are fundamental skills in mathematics. They are essential for various applications, such as converting fractions to percentages or when dealing with metrics and customary units.
However, the question asked to round to the nearest hundred, which seems to be a typographical mistake, because we usually round numbers to the nearest hundredth or to the nearest hundred as a whole number, but not to the nearest hundred as a decimal. Assuming it's a typo and meant the hundredth, the result is 1.33. Otherwise, 1.33 rounded to the nearest hundred as a whole number is simply 100 (since this is the closest hundred to 1.33).

Find the equation of the line that is parallel to y=-x+9 and contains the point (7,-13).
The equation of the line that is parallel to y = -x + 9 and passes through the point (7, -13) is y = -x - 6.
Now, we want to find the equation of a line that is parallel to this given line and passes through the point (7, -13). Since the new line is parallel, it will have the same slope of -1. Let's denote the equation of the new line as y = mx + b. We know the slope (m = -1), and we have a point (7, -13) that the line passes through. We can use this information to find the value of b.
To find b, we can plug in the coordinates of the point (7, -13) into the equation y = -x + b:
-13 = -1 * 7 + b
Now, solve for b:
b = -13 + 7
b = -6
Therefore, the value of b is -6.

what is the vertex of the quadratic function f(x)=1/2x^2+3x+3/2?
the vertex of the quadratic function
[tex]f(x)= \frac{1}{2}x^2+3x+\frac{3}{2}[/tex]
To find vertex we use formula x= -b/2a
from the given equation , a= 1/2 and b = 3
Now we plug in the values in the formula
[tex]x = \frac{-b}{2a}[/tex]
[tex]x= \frac{-3}{2\frac{1}{2}}=-3[/tex]
x coordinate of vertex is -3
Now plug in -3 for x in f(x)
[tex]f(-3)= \frac{1}{2}(-3)^2+3(-3)+\frac{3}{2}[/tex]
f(-3) = -3
the y coordinate of vertex is -3
So vertex is (-3,-3)
Answer:
(-3, -3)
Step-by-step explanation:
The standard form of a quadratic equation is [tex]y = ax^2+bx+c[/tex] where the coordinates of the highest point (x, y) indicate the vertex.
Here, [tex]a= \frac{1}{2} , b = 3[/tex] and [tex]c= \frac{3}{2}[/tex].

A veterinarian treated 7 dogs, 13 cats, 4 horses, and 3 ferrets. What percentage of his patients were small animals?
As per your defention, horses are the only thing considered "not small". To find the percentage, you take the number of what you are trying to find the percentage of divided by the total number.
So, 7 dogs + 13 cats + 3 ferrets = 23 Small animals
7 dogs + 13 cats + 3 ferrets + 4 horses = 27 total animals.
So,
[tex]\frac{23}{27}*100[/tex]
The reason we multiply by 100 is because the division gives us a decimal, and a percentage is a part out of 100.
So by doing the calculation we get
85.18%
Mathematics defines a percentage as a number or ratio expressed as fraction of 100.
It is denoted using % sign.
General formula to calculate percentage is:
[tex]\rm Percentage=\dfrac{\rm Value}{\rm Total\: value} \times 100%.[/tex]
For the given question, percentage of small animals is [tex]\rm 85.19\%.[/tex]
Calculation of percentage of small animals:[tex]\begin{aligned} \rm Total\: animals &= 7 + 13 + 4 + 3\\&= 27 \end[/tex]
[tex]\begin{aligned} \rm Number\:of\:small\:animals &= 7 + 13 + 3\\&= 23\end[/tex]
Small animals includes all animals except horses.
Therefore, percentage of small animals will be:
[tex]\rm \begin{aligned}\rm Percentage &= \dfrac{\rm Small \:animals}{\rm Total\:animals} \times 100\\\\ &= \dfrac{23}{27} \times 100\\\\ &= 85.19\% \end{aligned}[/tex]
