I think its d. Because it is to the nearest thousands. And you cannot find the long sides of the rectangle,because you need another one info. about the number of the long sides or the perimeter or the area. Im happy if i helped you

Answer:

a. 4.85

Step-by-step explanation:

im right

? = a+b

a = 3

(3+b)/3=3/b

b= -4.85 or 1.85

it cant be negive.

so ? = 3+1.85 = 4.85

A baker bought some flour. he used 2/5 of the flour to make bread and used the rest to make batches of muffins. if he used 16ib. of flour making bread and 2/3ib.for watch batch of muffins,how many batches of muffins did he make?

Answers

So if 16 is 2/5, then 16 ÷ 2 is 1/5 which is 8. Knowing this, we can multiply 8 by 3 to get the amount of flour he uses in muffins, which is 24. If he uses 2/3lbs for each batch of muffins, then you have to do 24 ÷ 2/3 which is 36. So he makes 36 batches of muffins. Hope this helps!

Answer:

The baker made 36 batches of muffins.

Step-by-step explanation:

Let the total amount of flour be x

We know he used 2/5 of the flour for bread, we also know he used 16 pounds for bread.

We can write this as :

[tex]\frac{2}{5}\times x=16[/tex]

Solving this we get;

[tex]2x=80[/tex]

So, x = 40

Means total amount of flour was 40 pounds and he used 16 pounds for bread, so the remaining is for batches of muffins, which is [tex]40-16=24[/tex] pounds

As each batch of muffin uses 2/3 pounds, so 24 pounds of flour will be used to bake :

[tex]\frac{24}{\frac{2}{3} }[/tex]

= [tex]\frac{24\times3}{2} =36[/tex]

Hence, the baker made 36 batches of muffins.

Algebra 2 Word Problem: Set up using 3 variables & 3 equations:
"A friend e-mails you the results of a recent high school swim meet. The e-mail states that 24 individuals placed, earning a combined total of 53 points. First place earned 3 points, second place earned 2 points, and third place earned 1 point. There were as many first-place finishers as second and third-place finishers combined."
A: Write a system of THREE equations that represents how many people finished in each place.
B: How many swimmers finished in first place, second and third?

Answers

Final answer:

To solve the word problem, we define three variables representing the number of first-, second-, and third-place finishers, respectively. We set up three linear equations based on the information provided, and by solving the system, we determined that 10 swimmers finished in first place, 8 in second, and 6 in third.

Explanation:

Setting Up the Equations

Let's denote the number of first-place finishers as x, second-place finishers as y, and third-place finishers as z. According to the information provided:

Total number of individuals placed: x + y + z = 24

Total points earned: 3x + 2y + z = 53

The number of first-place finishers equals the number of second and third-place finishers combined: x = y + z

This is our system of three equations.

Solving the System of Equations

To solve for the number of swimmers in each place, use the substitution or elimination method:

Since x = y + z, substitute x in the first two equations.

You'll get two equations with two variables (y and z).

Solve these equations to find the values of y and z.

Finally, substitute the found y and z back into x = y + z to get the value of x.

By solving this system, we find that 10 swimmers finished in first place, 8 swimmers finished in second, and 6 swimmers finished in third.

Solve system of equations using any method 2x-6y=8 and 2x-6y=3

Answers

Let z be any number (like x would be)

if we set z equal to 2x-6y, then we get z = 2x-6y

The system 

2x-6y = 8
2x-6 = 3

turns into this new system

z = 8
z = 3

but z is a single number. It can't be both 8 and 3 at the same time. So there are no solutions
The answer is no solution. If you use elimination, by subtracting the second equation from the first, you come out with 0=5, which is a false statement. Therefore, there is no solution.

Write two equations in standard form that are equivalent to the given equation.
1.5x+10y=15
2.-9x-12y=6
3.-2x+4y=-5

Answers

1.) 5x + 10y = 15 => x + 2y = 3 => 3x + 6y = 9

2.) -9x - 12y = 6 => 9x + 12y = -6 => 3x + 4y = -2

3.) -2x + 4y = -5 => 2x - 4y = 5 => 4x - 8y = 10
Final answer:

Equivalent equations can be created by multiplying or dividing the original equation by any nonzero constant. Lifting the coefficients of the given equations accordingly can create multiple equivalent equations.

Explanation:

To create two equations that are equivalent to the given equation 1.5x + 10y = 15, we can multiply the entire equation by a nonzero constant.  By multiplying by 2, we obtain 3x + 20y = 30. Conversely, dividing the original equation by 3 gives us 0.5x + 3.3333y = 5.

Applying the same concept to the second equation -9x - 12y = 6, multiplying by 2 gives us -18x - 24y = 12, and dividing by 3 gives us -3x - 4y = 2.

For the third equation -2x + 4y = -5, multiplying by any nonzero constant yields an equivalent equation. Multiplying by 2, we get -4x + 8y = -10, and dividing by 2 gives us -1x + 2y = -2.5.

Lena is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges
$115
and allows unlimited mileage.
Company B has an initial fee of
$55
and charges an additional
$0.80
for every mile driven.
For what mileages will Company A charge less than Company B?
Use
m
for the number of miles driven, and solve your inequality for
m
.

Answers

Cost of Company A: 114
Cost of Company B: 55 + 0.8m
Mileage where A is less than B:
114 < 55 + 0.8m
59 < 0.8m
m > 73.75 miles
Company A: 115.00 initial, 0.00 per mile
Company B: 55.00 initial, 0.80 per mile
Set the thing you want to be less than (Company A) less than the other (Company B).
115 < 55 + .8m (solve for m.)
60 < .8m
75 < m
Company A will charge less than Company B when the number of miles is greater than 75. (The charge will be equal at 75 miles.)

Answer:

Step-by-step explanation:

I'm not sure why though this is right because I graphed it, and I don't see how that could be the right answer.

Answer:

Option A - It shrinks the graph vertically to 1/2 its original height.

Step-by-step explanation:

Given : In the function [tex]y=\frac{1}{2} x^2[/tex]

To find : What effect does the number [tex]\frac{1}{2}[/tex] have on the graph, as compared to the graph of the function [tex]y=x^2[/tex] ?

Solution :

The parent function is [tex]y=x^2[/tex]

We have given that  [tex]\frac{1}{2}[/tex] number is multiply to the parent function.

When the unit is multiply to the function gives you vertical stretch or compression

i.e, f(x)→ bf(x), o<b<1 then the function is vertically compressed.

[tex]y=\frac{1}{2} x^2[/tex] As  [tex]0<\frac{1}{2}<1[/tex] means there is vertical compression or shrinks.

Therefore, Option A is correct.

It shrinks the graph vertically to 1/2 its original height.

A cone has a diameter of 10 inches. If its height is twice its radius, about what is the volume of the cone in cubic inches? Use 3.14 for π.

Answer with Step-by-step explanation:

The volume of cone is given by:

V=[tex]\dfrac{1}{3}\times \pi r^2h[/tex]

Where r is the radius of cone and h is height

r=d/2 where d is the diameter

Hence, here r=5 in.

height is twice its radius ⇒ h=10 in.

V=[tex]\dfrac{1}{3}\times 3.14\times 5^2\times 10[/tex]

V=261.66 in³

Hence, Volume of cone is:

False:
[tex]f(x)=x^2 \\f(3+5)=(3+5)^2=8^2=64 \\f(3+5)=f(3)+f(5)=3^2+5^2=9+25=34 [/tex]
Final answer:

The statement is true for linear functions, but not in general for all functions.

Explanation:

The statement is true if f(x) is a linear function.

However, it is not true in general for all functions, so the statement is false.

An example of a linear function where the statement is true would be f(x) = 2x.

If we substitute s + t into the function, we get f(s + t) = 2(s + t) = 2s + 2t.

On the other hand, if we substitute f(s) + f(t) into the function, we get f(s) + f(t) = 2s + 2t.

Therefore, the equality holds and the statement is true for linear functions.

at the party 2/5 of the pizzas ordered had pepperoni .The kids ate only 1/3 of the pepperoni pizzas, while the parents ate all of the remaining pizza. How much of all the pizza ordered was eaten by the kids ? ...?

Answers

Here is the solution for the given problem above.
Given that in the whole pizza, 2/5 of it is pepperoni (which makes 3/5 of the pizza has different flavor). What we are going to find is how much of all the pizza ordered was eaten by the kids, since only 1/3 of the pepperoni pizza is eaten by them. So to solve this, we will multiply 1/3 by 2/5 and the answer would be 2/15. Therefore, the answer is 2/15 of the pizza was eaten by the kids.
