A. 24.5 miles
B. 50 miles
B. 50 miles
C. 59.5 miles
C. 59.5 miles
D. 200 miles
D. 200 miles
Answer:
B
Step-by-step explanation:
The trip is a total of 50 miles.
You are trying to find 100% of the trip, so first, A and D can be eliminated because of the extreme values.
Between B and C, you would divide them from 100, b would give you 100, and c would give you 119.
Based on this, 35 miles of a 50 mile trip is equal to 70% of 100%
Hope this helps! Have a great day!
1/4 divided by 1 1/8
pls help ill give big brain
Answer:
2/9
Step-by-step explanation:
1/4 divided by 1 1/8.
First rewrite 1 1/8 as an improper fraction.
You now have 1/4 divided by 9/8.
When dividing by a fraction you multiply by the reciprocal.
You now have 1/4 * 8/9.
Now Multiply the numerators across and the denominators across to get 8/36.

Max attempts three free throws during a basketball game. Identify the sample space (the correct list of possible outcomes) for his results.
S = success, F = fail
The notation SFS means he succeeded on the first try, missed on the second try, and succeeded on the third try.
A. {SSSS, SFSF, FFFF}
B. {SSS, SSF, SFS, SFF, FSS, FSF, FFS, FFF}
C. {SS, FF, SF, FS)
D. SSS, SFS, FFF}
Answer:
B
Step-by-step explanation:
An experiment's or random trial's sample space is the set of all conceivable outcomes or results. The correct option is B, {SSS, SSF, SFS, SFF, FSS, FSF, FFS, FFF}.
What is a sample space?An experiment's or random trial's sample space is the set of all conceivable outcomes or results. The sample space can also be described as the collection of all potential outcomes of a random experiment. Set notation is commonly used to represent a sample space, and the potential ordered outcomes, or sample points, are given as elements in the set.
Given that Max attempts three free throws during a basketball game. And in each attempt, he can be either successful represented by S and Fail represented by F.
Since there are only 2 outcomes, therefore, the number of outcomes that are possible for three trials are,
Number of outcomes = 2³ = 8
Hence, the only option that has 8 outcomes is {SSS, SSF, SFS, SFF, FSS, FSF, FFS, FFF}.

Stephen has $500 in an account for 9 months at a compound interest rate of 7.5%. At the end of 9 months, how much money is in his account?
Answer:
8.12
Step-by-step explanation:
Stephen has approximately $532.72 in his account at the end of 9 months with a 7.5% compound interest rate.
We can use the formula for compound interest to find the amount of money in Stephen's account at the end of 9 months:
A =P \((1 + r/n)^_(nt)\)
where:
A is the amount of money in the account at the end of the period
P is the principal (initial amount) in the account
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the time (in years)
We know that P = $500, r = 0.075 (since the interest rate is 7.5%), n = 12 (since the interest is compounded monthly), and t = 9/12 (since 9 months is three-quarters of a year). Substituting these values into the formula, we get:
A = \($500(1 + 0.075/12)^_{(12*(9/12))\) = \($532.72\)
Therefore, Stephen has approximately $532.72 in his account at the end of 9 months.

PLEASE HELP!! what is the equation for the parabolic function that goes through the points (-3, 67) (-1, 1) and has a stretch factor of 9
Answer:
\(f(x)=9(x+\frac{1}{6})^2-\frac{21}{4}\)
Step-by-step explanation:
So, we need to find the equation of a parabolic function that goes through the points (-3,67) and (-1,1) and has a stretch factor of 9.
In other words, we want to find a quadratic with a vertical stretch of 9 that goes through the points (-3,67) and (-1,1).
To do so, we first need to write some equations. Let's use the vertex form of the quadratic equation. The vertex form is:
\(f(x)=a(x-h)^2+k\)
Where a is the leading coefficient and (h,k) is the vertex.
Since a is the leading coefficient, it's also our stretch factor. Thus, let a equal 9.
Also, we have two points. We can interpret them as functions. In other words, (-3,67) means that f(-3) equals 67 and (-1,1) means that f(-1) equals 1. Write the two equations:
\(f(x)=a(x-h)^2+k\\f(-3)=67=9((-3)-h)^2+k\)
And:
\(f(x)=a(x-h)^2+k\\f(-1)=1=9((-1)-h)^2+k\)
Now, we essentially have a system of equations. Thus, to find the original equation, we just need to solve for the vertex. To do so, first isolate the k term in the second equation:
\(1=9(-1-h)^2+k\\k=1-9(-1-h)^2\)
Now, substitute this value to the first equation:
\(67=9(-3-h)^2+k\\67=9(-3-h)^2+(1-9(-1-h)^2)\)
And now, we just have to simplify.
First, from each of the square, factor out a negative 1:
\(67=9((-1)(h+3))^2+(1-9(((-1)(h+1))^2)\)
Power of a product property:
\(67=9((-1)^2(h+3)^2)+(1-9((-1)^2(h+1)^2))\)
The square of -1 is positive 1. Thus, we can ignore them:
\(67=9(h+3)^2+(1-9(h+1)^2)\)
Square them. Use the trinomial pattern:
\(67=9(h^2+6h+9)+(1-9(h^2+2h+1))\)
Distribute:
\(67=(9h^2+54h+81)+(1-9h^2-18h-9)\)
Combine like terms:
\(67=(9h^2-9h^2)+(54h-18h)+(81+1-9)\)
The first set cancels. Simplify the second and third:
\(67=36h+73\)
Subtract 73 from both sides. The right cancels:
\(67-73=36h+73-73\\36h=-6\)
Divide both sides by 36:
\((36h)/36=(-6)/36\\h=-1/6\)
Therefore, h is -1/6.
Now, plug this back into the equation we isolated to solve for k:
\(k=1-9(-1-h)^2\)
First, remove the negative by simplifying:
\(k=1-9((-1)(h+1))^2\\k=1-9((-1)^2(h+1)^2)\\k=1-9(h+1)^2\)
Plug in -1/6 for h:
\(k=1-9(-\frac{1}{6}+1)^2\)
Add. Make 1 into 6/6:
\(k=1-9(-\frac{1}{6}+\frac{6}{6})^2\\ k=1-9(\frac{5}{6})^2\)
Square:
\(k=1-9(\frac{25}{36})\)
Multiply. Note that 36 is 9 times 4:
\(k=1-9(\frac{25}{9\cdot4})\\ k=1-\frac{25}{4}\)
Convert 1 into 4/4 and subtract:
\(k=\frac{4}{4}-\frac{25}{4}\\ k=-\frac{21}{4}\)
So, the vertex is (-1/6, -21/4).
Now, plug everything back into the very original equation with 9 as a:
\(f(x)=a(x-h)^2+k\\f(x)=9(x+\frac{1}{6})^2-\frac{21}{4}\)
And this is our answer :)

Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
