Andrew has 10 more goldfish than Todd. Together, they have 50. goldfish. How many goldfish does each boy have?

Answers

Answer 1
Todd has x amount of gold fish
Andrew has x + 10 amount of gold fish
They have 50 in all

x +(x+10) = 50

2x + 10 = 50

2x +10 (-10) = 50 (-10)

2x/2 = 40/2

x = 20

Todd has x amount of goldfish, so he has 20 goldfish
Andrew has (x + 10) amount of goldfish, so he has 30, because 20 + 10 = 30

Jose is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices. Company A charges $108 and allows unlimited mileage. Company B has an initial fee of $75 and charges an additional $0.60 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

108 < 75 + 0.60m
108 - 75 < 0.60m
33 < 0.60m
33 / 0.60 < m
55 < m...or m > 55...company A will charge less if it is driven 56 or more miles

Final answer:

Jose should rent a truck from Company A if he plans to drive more than 55 miles, as it will charge less than Company B beyond this mileage.

Explanation:

To determine for what mileages Company A will charge less than Company B, we set up an inequality comparing the total cost for each company and solve for m (the number of miles driven).

The cost for Company A is a flat rate of $108, so it does not depend on mileage. The cost for Company B includes an initial fee of $75 plus $0.60 per mile. We set up the inequality as follows:

Company A \< Company B

$108 < $75 + $0.60m

$108 - $75 < $0.60m

$33 < $0.60m

$33 / $0.60 < m

55 < m

Therefore, Company A will charge less than Company B for any number of miles greater than 55. So, if Jose plans to drive more than 55 miles, he should choose Company A for a cheaper rate.

In Seattle, the tax on a property assessed at $570,000 is $12,540. If tax rates are proportional in this city, how much would the tax be on a property assessed at $460,000?

Answers

12,540 / 570,000 = x / 460,000
cross multiply
570,000x = 5768400000
x = 5768400000 / 570,000
x = 10,120 <=== tax on 460,000

Final answer:

To find the property tax on a $460,000 property, first, find the tax rate by dividing the known tax of $12,540 by the assessed value of $570,000 to get approximately 0.022. Then multiply $460,000 by this tax rate to get an estimated tax of $10,120.

Explanation:

To calculate the property tax on a property assessed at $460,000 in Seattle, given the tax rate is proportional, we can use the tax information from another property as a reference. In this case, we know a property assessed at $570,000 has a tax of $12,540. This allows us to find the tax rate by dividing the tax amount by the assessed value of the property.

Step 1: Determine the tax rate.

Tax Rate = Tax / Assessed Value

Tax Rate = $12,540 / $570,000

Tax Rate ≈ 0.022

Step 2: Calculate the tax for the property assessed at $460,000 using the tax rate.

Tax = Assessed Value × Tax Rate

Tax = $460,000 × 0.022

Tax ≈ $10,120

Thus, the property tax on a property assessed at $460,000 would be approximately $10,120, assuming the tax rates are indeed proportional.

(3x6÷2)v+10=3²v+9 (Need work)

Answers

Final answer:

The student's equation simplifies to 9v + 10 = 9v + 9. Upon further simplification, it becomes apparent that the equation is a contradiction and has no solution.

Explanation:

The student is asking about the solution to the equation (3x6÷2)v+10=3²v+9. The first step in solving this equation is to simplify the terms. We start by simplifying the multiplication and division in the first part of the equation (3x6÷2), which equals 9 since 3 times 6 is 18 and 18 divided by 2 is 9. Therefore, the equation simplifies to 9v + 10 = 3²v + 9. Next, we simplify 3², which is 3 raised to the power of 2, meaning 3 times itself, which results in 9. The equation now reads 9v + 10 = 9v + 9.

With the equation simplified, we notice that the terms containing v are equal on both sides of the equation. This indicates that we may be dealing with an identity or a contradiction depending on the constants. Subtracting 9v from both sides yields 10 = 9, which is clearly not true. Therefore, we conclude that the equation is a contradiction, and there is no solution for v that would make the equation true.

Final answer:

To solve the equation (3x6÷2)v+10=3²v+9, we need to follow the order of operations and solve for the variable v. However, the equation is inconsistent and has no solution.

Explanation:

To solve the equation (3x6÷2)v+10=3²v+9, we need to follow the order of operations and solve for the variable v. Let's break it down step by step:

Start by performing the division 3x6÷2 = 18÷2 = 9.

Now rewrite the equation as 9v+10=9v+9.

Subtract 9v from both sides of the equation to isolate the constants: 10 = 9.

Since 10 is not equal to 9, the equation is inconsistent and has no solution.

Therefore, there is no value of v that satisfies the equation.

The line integral of (2x+9z) ds where the curve is given by the parametric equations x=t, y=t^2, z=t^3 for t between 0 and 1. Please don't respond if you can't explain how to get out of an impossible square root. Thanks

Answers

Let r = (t,t^2,t^3)

Then r' = (1, 2t, 3t^2)

General Line integral is:
[tex]\int_a^b f(r) |r'| dt[/tex]

The limits are 0 to 1
f(r) = 2x + 9z = 2t +9t^3
|r'| is magnitude of derivative vector [tex]\sqrt{(x')^2 + (y')^2 + (z')^2}[/tex]

[tex]\int_0^1 (2t+9t^3) \sqrt{1+4t^2 +9t^4} dt [/tex]

Fortunately, this simplifies nicely with a 'u' substitution.

Let u = 1+4t^2 +9t^4

du = 8t + 36t^3  dt

[tex]\int_0^1 \frac{2t+9t^3}{8t+36t^3} \sqrt{u} du \\ \\ \int_0^1 \frac{2t+9t^3}{4(2t+9t^3)} \sqrt{u} du \\ \\ \frac{1}{4} \int_0^1 \sqrt{u} du[/tex]

After integrating using power rule, replace 'u' with function for 't' and evaluate limits:
[tex]=\frac{1}{4} |_0^1 (\frac{2}{3}) (1+4t^2 +9t^4)^{3/2} \\ \\ =\frac{1}{6} (14^{3/2} - 1)[/tex]
Final answer:

To evaluate the line integral, calculate the arclength element and substitute it into the integral. Expand the expression inside the square root, multiply it by (2x+9z), and integrate term by term.

Explanation:

To evaluate the line integral of (2x+9z) ds where the curve is given by the parametric equations x=t, y=t^2, z=t^3 for t between 0 and 1, we need to find the arclength element ds and substitute it into the integral. The arclength element ds can be calculated using the formula ds = sqrt(dx^2 + dy^2 + dz^2). In this case, dx = dt, dy = 2t dt, and dz = 3t^2 dt. Substituting these values into the arclength element formula, we get ds = sqrt(dt^2 + 4t^2 dt^2 + 9t^4 dt^2) = sqrt(1 + 4t^2 + 9t^4) dt.

Substituting ds into the line integral, we get the integral of (2x+9z) * sqrt(1 + 4t^2 + 9t^4) dt. To evaluate this integral, you can expand the expression inside the square root, multiply it by (2x+9z), and integrate term by term.

However, it seems that there might be a typo in the original question regarding the curve parametrization. The curve given by x=t, y=t^2, z=t^3 is actually a parabolic curve, not a line. If you need further clarification or assistance, please let me know.

Which expression results in a product that is rational?

(b)square root of 8 times square root of 10
(c) square root of 9 times square root of 10
(d)square root of 10 times square root of 10

Answers

Final answer:

The expression that results in a rational product is √10 times √10, as this simplifies to the rational number 10.

Explanation:

To find which expression results in a product that is a rational number, we need to identify which pair of square roots can be multiplied to produce a non-radical number.

Multiplication of square roots is analogous to the multiplication of exponents. When the same base is multiplied, the exponents are added. Utilizing this property, we know:

√7 × √10 = √(7 × 10) = √70 (which is irrational since 70 is not a perfect square).

√8 × √10 = √(8 × 10) = √80 (which is irrational since 80 is not a perfect square).

√9 × √10 = √(9 × 10) = √90 (which is irrational since 90 is not a perfect square).

√10 × √10 = √(10 × 10) = √100 = 10 (which is rational since 100 is a perfect square).

Therefore, the expression that results in a rational product is √10 × √10, which simplifies to 10.

One integer is 2​ times another. If the product of the two integers is 32, then find the integers

Answers

Final answer:

The two integers that satisfy the conditions of being twice of each other and having a product of 32 are either (4, 8) or (-4, -8).

Explanation:

The two integers as x and y, with y being 2 times x (y = 2x). According to the problem, the product of these two integers is 32 (x * y = 32). If we substitute y in the equation with 2x, we obtain the following: x * 2x = 32. Simplifying this equation gives us a quadratic equation, x² = 16.

To find x, we take the square root of both sides. The square root of 16 is 4, so x can be either 4 or -4. Consequently, y can be either 8 or -8, depending on whether x is positive or negative.

Therefore, the two sets of integers that satisfy the equation x*y = 32 are (4, 8) and (-4, -8), as both pairs have a product of 32 and one integer is exactly twice the other.
