eight less than a number s is three more than four times a number t. solve for s

Answers

The solution is s = 4t + 11.

Let's translate the problem into an equation:

s - 8 = 4t + 3

Now we can solve for s by adding 8 to both sides of the equation:

s = 4t + 3 + 8

Finally, we can simplify the equation by combining the constant terms:

s = 4t + 11

Therefore, the solution is:

s = 4t + 11

What is the value of the expression 4x+y2y−x when x = 2 and y = 4?

Answers

Final answer:

To solve the expression 4x+y2y−x, we substitute the values x=2 and y=4, obtaining the result 262.

Explanation:

The question asks what is the value of the mathematical expression 4x+y2y−x when x = 2 and y = 4. To solve this, we first substitute the given values of x and y into the expression. The expression becomes 4*2 + 4²*4 - 2 = 8 + 64 *4 - 2 = 8 + 256 - 2 = 262. Therefore, the value of the expression when x = 2 and y = 4 is 262.

Since the perimeters are the same, we should equate:

n + n+0.6 = 2n + n+0.1

(multiplying by 2 isn't going to change the solution, so I'm not doing that here)

This simplifies as follows:

n + n+0.6 = 2n + n+0.1 =>
2n + 0.6 = 3n + 0.1 =>
0.6 - 0.1 = 3n - 2n =>
n = 0.5

The perimeters are (now we should take the 2 into account):

2*(n + n+0.6) = 2*(0.5 + 0.5 + 0.6) = 3.2
2*(2n + n + 0.1) = 2*(1.0 + 0.5 + 0.1) = 3.2

As expected, they are equal.

Simplify (−34.67)0

Answers

Final answer:

Any non-zero number raised to the power of zero is equal to 1, so [tex](-34.67)^0[/tex] simplifies to 1.

Explanation:

The question asks us to simplify  [tex](-34.67)^0[/tex]. In mathematics, any non-zero number raised to the power of zero is equal to 1. This rule is known as the zero exponent rule and is an important concept in algebra.

Applying this rule to the given expression, regardless of the value of −(34.67), the whole expression to the power of zero will simply be:

[tex](-34.67)^0[/tex] = 1

From a more abstract perspective, raising a number to the power of 0 can be seen as a special case of exponentiation that preserves the multiplicative identity. In other words, it serves as the identity element for multiplication in the set of non-zero real numbers. This property is consistent with the general pattern observed in exponentiation, where raising a number to different powers yields specific results based on mathematical principles and definitions.

Then since you need to move the decimal over to make it in scientific notation, you add 1 to the 10^-8 , then you get 10^-7. The problem in scientific notation is 3.726×10^-7.

The correct scientific notation is 3.762x10⁻⁷.

Given that  (4.18x10⁻⁴)(9x10⁻⁴).

4.18x9=37.62

10⁻⁴x10⁻⁴=10⁻⁸

So, the answer is 37.62x10⁻⁸. To obtain scientific notation the decimal moves to the left which gives 3.762x10⁻⁷.

A plumber has a 50 foot piece of PVC pipe. how many 9/5 foot pieces can be cut from the 50 foot piece?

Answers

Answer:

[tex]27\frac{7}{9}\approx 27[/tex] pipes.

Step-by-step explanation:

We have been given that a plumber has a 50 foot piece of PVC pipe. We are asked to find the number of 9/5 foot pieces of pipes that could be cut from the 50 foot piece.

To find the number of 9/5 foot pieces of pipes, we will divide total length of PVC pipe by 9/5 foot.

[tex]\text{Number of 9/5 foot pieces of pipes}=50\div \frac{9}{5}[/tex]

Convert to multiplication problem:

[tex]\text{Number of 9/5 foot pieces of pipes}=50\times \frac{5}{9}[/tex]

[tex]\text{Number of 9/5 foot pieces of pipes}=\frac{250}{9}[/tex]

[tex]\text{Number of 9/5 foot pieces of pipes}=27\frac{7}{9}[/tex]

[tex]\text{Number of 9/5 foot pieces of pipes}\approx 27[/tex]

Therefore, the plumber can make [tex]27\frac{7}{9}\approx 27[/tex] pipes.

28 of the  [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece.

Given the following data;

Total length of PVC pipe = 50 footRequired length of PVC pipe = [tex]\frac{9}{5}[/tex] foot

In this exercise, you're required how many  [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece. To do this we would divide the 50 foot piece of PVC pipe by [tex]\frac{9}{5}[/tex].

[tex]50[/tex] ÷ [tex]\frac{9}{5}[/tex] = [tex]\frac{50}{\frac{9}{5}}[/tex]

Simplifying the equation, we have;

[tex]\frac{50 \;X \;5}{9}[/tex]

[tex]\frac{250}{9}[/tex]

Number of pipes = 27.77 ≈ 28 pipes.

Therefore, 28 of the  [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece.
