Answer:

2750

Step-by-step explanation:

As there are 11 players on the field, each averaging 250 pounds, this means that we can add 250 11 times, 1 for each player. Another way to say this would be to multiply 250 and 11, as we are adding 250 11 times. Our answer is then 250*11 = 2750.

Answer:

Option 1. Lynn, only

Step-by-step explanation:

The correct question is

Listen Lynn, Jude, and Anne were given the function f(x)=-2x^2+32, and they were asked to find f(3). Lynn's answer was 14, Jude's answer was 4, and Anne's answer was (+/-)4. Who is correct?

1. Lynn, only

2. Jude, only

3. Anne, only

4. Both Lynn and Jude

we have

[tex]f(x)=-2x^{2} +32[/tex]

This is a vertical parabola open downward (leading coefficient is negative)

The vertex is a maximum

we know that

f(3) means, the value of f(x) when the value of x is equal to 3

so

For x=3

substitute in the quadratic equation and solve for f(x)

[tex]f(3)=-2(3^{2}) +32[/tex]

[tex]f(3)=-18 +32[/tex]

[tex]f(3)=14[/tex]

therefore

Lynn's answer is correct

To determine the value of the function f(x) = 2x + 32 at x=3, we substitute x with 3, and solve to obtain f(3) = 38. Therefore, all students' answers were incorrect.

In the function f(x) = 2x + 32, to find the value of f(3), you first need to substitute 'x' with 3. The equation it becomes f(3) = 2 * 3 + 32

By solving the equation, you obtain is f(3) = 6 + 32 which equals to f(3) = 38.

Thus, all the students, Lynn, Jude, and Anne, unfortunately provided incorrect answers.

Answer:

Well, we know x has to add up to 180 degrees since a triangle has 180 degrees in it!

63 + 36 = _99__

180 - 99 = 81

81 = x

180 - 81 = 99

99 is z

99 + 13 = 112

180 - 112 = 68

68 is y

Since 13 is an angle measurement. We add to get 180.

68 = y

99 = z

There are 165 different subcommittees possible.

To calculate the number of different subcommittees possible, we can use the combination formula. The number of different subcommittees is equal to the number of ways to choose 3 members out of 11. This can be calculated using the formula C(n, r) = n! / (r! (n - r)!), where n is the total number of members and r is the number of members in the subcommittee.

Plugging in the values, we have C(11, 3) = 11! / (3! (11 - 3)!) = 165. Therefore, there are 165 different subcommittees possible.

8 solid iron sphere with radius 'a cm' each are melted to form a sphere with radius 'b cm' then the ratio of a:b is 1 : 2

Solution:

Given that 8 solid iron sphere with radius 'a cm' each are melted to form a sphere with radius 'b cm'

Need to find the ratio of a:b

As 8 solid iron sphere with radius 'a cm' each are melted to form a sphere with radius 'b cm'.  

For sake of simplicity, let volume of 1 sphere of radius a cm is represented by [tex]V_a[/tex] and volume of 1 sphere of radius b cm is represented by [tex]V_b[/tex]

So volume of 8 solid iron sphere with radius 'a cm' = volume of  1 solid iron sphere with radius 'b cm'

[tex]=>8 \times} \mathrm{V}_{\mathrm{a}}=\mathrm{V}_{\mathrm{b}}[/tex]

[tex]\frac{\mathrm{V}_{\mathrm{a}}}{\mathrm{V}_{\mathrm{b}}}=\frac{1}{8}[/tex]  ---- eqn 1

[tex]\text {Let's calculate } {V}_{a} \text { and } V_{b}[/tex]

Formula for volume of sphere is as follows:

[tex]V=\frac{4}{3} \pi r^{3}[/tex]

Where r is radius of the sphere

Substituting r = a cm in the formula of volume of sphere we get

[tex]V_{a}=\frac{4}{3} \pi r^{3}=\frac{4}{3} \pi a^{3}[/tex]

Substituting r = b cm in the formula of volume of sphere we get

[tex]V_{b}=\frac{4}{3} \pi r^{3}=\frac{4}{3} \pi b^{3}[/tex]

[tex]\text { Substituting value of } V_{a} \text { and } V_{b} \text { in equation }(1) \text { we get }[/tex]

[tex]\frac{\frac{4}{3} \pi a^{3}}{\frac{4}{3} \pi b^{3}}=\frac{1}{8}[/tex]

[tex]\begin{array}{l}{=>\frac{\frac{4}{3} \pi a^{3}}{\frac{4}{3} \pi b^{3}}=\frac{1}{8}} \\\\ {=>\left(\frac{a}{b}\right)^{3}=\left(\frac{1}{2}\right)^{3}} \\\\ {=>\frac{a}{b}=\frac{1}{2}}\end{array}[/tex]

a : b = 1 : 2

Hence the ratio of a:b is 1 : 2

Final answer:

The ratio of the radius 'a' of the original smaller spheres to the radius 'b' of the new larger sphere formed by melting the 8 smaller spheres together is 1:2, obtained by equating the volumes and simplifying.

Explanation:

The question pertains to using the concept of volumes of spheres in Mathematics to find the ratio of radii of the original smaller spheres to the new larger sphere formed by melting them together. Given that there are 8 solid iron spheres each with radius 'a cm', and they are melted to form one single sphere with radius 'b cm', we preserve the volume during the melting process.

We know that the volume of a sphere is calculated using the formula [tex]V=\frac{4}{3}\pi r^{3}[/tex]. When combining the volumes of the 8 smaller spheres into one large sphere, the volumes on both sides must be equal since no material is lost during melting. The equation to find the volume of the large sphere is [tex]V=8(\frac{4}{3}\pi a^{3}) = \frac{4}{3}\pi b^{3}[/tex].
Simplifying this equation, we obtain the cubic ratio of radii a³/b³ = 1/8. Taking the cube root of both sides, the simple ratio of the radii is a/b = ∛[1/8], which simplifies to a/b = 1/2. Therefore, the ratio of the radius of the smaller sphere to the radius of the larger sphere, a:b, is 1:2,

The average per cost is $19.25.

Step-by-step explanation:

Given:

The fee paid by cat owner = $269.50. Total visits he made that year 14.

Now, to find the average per cost.

So, to get the average per cost we divide the total fee by total visits:  

Average per cost = Total fee ÷  Total visits

                             =  [tex]269.50\div 14[/tex]

                             =  [tex]19.25[/tex]

Therefore, average per cost is $19.25.

Answer:

The Average cost of per visit to the vet  = $ 19.25

Step-by-step explanation:

Here, the total visits to the vet in a  year = 14

Also, the total amount paid to the vet in a year = $269.50

Now, Let us assume the average cost per vet visit = m

So,[tex]\textrm{Average cost of per visit}  = \frac{\textrm{Total amount paid in n visits}}{\textrm{ n visits}}\\ \implies  m = \frac{269.50}{14}  = 19.25[/tex]

or,  m = $ 19.25

Hence, the Average cost of per visit to the vet  = $ 19.25

Paying an extra $100 each month on a $60,000 loan with an 8% APR over 25 years will reduce the loan term and total interest paid. To calculate the effect, compute the total cost of the loan with and without the extra payments and subtract these two sums.

The subject at hand pertains to understanding the impact of additional payments on a loan, which falls under the domain of financial mathematics. Let's dissect the impact of paying an extra $100 per month on a $60,000 loan with an 8% annual interest rate over 25 years.

Firstly, we need to calculate the monthly payment for a 25-year loan of $60,000 at 8% interest. This can be calculated by using a loan calculator or the loan payment formula. Then, calculate the total cost of the loan by multiplying this monthly payment by the number of months in the loan term (25 years x 12 months).

You then do a similar calculation, but this time add an extra $100 to the monthly payment. The extra repayment will reduce the loan term and decrease the total interest paid. To see the effect, compare the total cost of the loan with and without the extra $100.

Therefore, the difference between these two sums will give you the saved amount due to the additional $100 monthly payment. This saving is the effect of making additional payments on the loan.

Making additional monthly payments can shorten the loan term and save money on interest payments.

To calculate the effect of making additional monthly payments on the cost of the loan, we can compare the total interest paid and the duration of the loan with and without the additional payments. Without any additional payments, the monthly payment for a $60,000 loan with an 8% APR and a 25-year term would be $459.18. With an additional $100 each month, the monthly payment would increase to $559.18.

By making the additional $100 payments, the loan would be paid off faster, reducing the term from 25 years to approximately 17 years and saving the borrower 8 years of monthly payments. Additionally, the total interest paid over the course of the loan would also be significantly reduced compared to just paying the required monthly payments.

In summary, making extra monthly payments of $100 can shorten the loan term and save the borrower money on interest payments.

Answer: 10.22

Step-by-step explanation:

Standard Deviation = square root of variance 104.44 = 10.22

Final answer:

To find the standard deviation from the variance of 104.4, you take the square root of the variance, resulting in a standard deviation of approximately 10.22.

Explanation:

If the variance for a data set is 104.4, to find the standard deviation, you take the square root of the variance. The formula to calculate the standard deviation (s) from the variance (σ²) is:

s = √σ²

Applying this formula, the standard deviation would be s = √104.4. Using a calculator, you would get:

s ≈ 10.22

Thus, the standard deviation for the data set with a variance of 104.4 is approximately 10.22.

Answer:

Their mass at the start was 400 kg.

Step-by-step explanation:

Given:

The tyres on a car during a grand prix race are reduced in mass by 3%. Their mass is 388 kg at the end of the race.

Now, to find the mass at the start.

Let the mass at the start be [tex]x[/tex].

According to question:

[tex]x - 3 \%ofx= 388[/tex]

⇒[tex]x-\frac{3}{100}\times x = 388[/tex]

⇒[tex]x-0.03x =388[/tex]

⇒[tex]0.97x=388[/tex]

Dividing both sides by 0.97 we get:

⇒[tex]x=400[/tex]

Therefore, their mass at the start was 400 kg.

To find the original mass of the tyres before the 3% decrease,  we make a simple percentage calculation. By setting up the equation 97/100 * x = 388, we find that the original mass of the tyres was 400 kg.

The question posted is a mathematics problem related to understanding percentages and its application to real-life situations such as a Grand Prix race.

Given that the tyres at the end of the race have a mass of 388 kg, which is 97% of their original mass (since they lost 3%), we can find their original mass by setting up a simple percentage equation. We denote the original mass as 'x' and set up the equation: 97/100 * x = 388. To solve for 'x', we divide both sides of the equation by 97/100, which is equivalent to multiplying by its reciprocal, 100/97.

The solution to the problem is then calculated as following: x = 388 * (100/97) = 400 kg.

Hence, the original mass of the tyres was 400 kg.
