To convert 330 seconds into minutes which ratio would you multiply by

1 answer:

5 0

$60s = 1 min \ |\div 60\\\\ 1 s = \frac{1}{60}min\\\\ So 330 s = 330 \cdot \frac{1}{60}min = \frac[330}{60}min = \frac{33}{6}=5\frac{3}{6}=5\frac{1}{2} \ min$

What is the second step to prove that Sn=>2+2^2+2^3+...+2^n=2(2^n-1)?

EleoNora [17]

Answer:

Assume that Sn is valid for n = k and prove that Sn is valid for n = k + 1.

Step-by-step explanation:

This is the second step in the principal of mathematical induction. The three steps in the principals of mathematical induction are:

1. show that something works for the first case (base or anchor step)

2. assume that it works for any particular step (inductive hypothesis), and then

3. show that it works for the next case (inductive step)

p. 621 in textbook

It's weird that they put steps 2 & 3 together, but it was correct on the test so ¯\_(ツ)_/¯

Which of the following expressions does not equal: the sixth root of 81x^4y^8

DerKrebs [107]

$\sqrt[6]{81x^4y^8}=\left[3^4x^4(y^2)^4\right]^\frac{1}{6}=\left[\left(3xy^2\right)^4\right]^\frac{1}{6}\\\\=\left(3xy^2\right)^{4\cdot\frac{1}{6}}=\left(3xy^2\right)^\frac{2}{3}\to A\\\\=\left(3xy^2\right)^\frac{2}{3}=\sqrt[3]{\left(3xy^2\right)^2}=\sqrt[3]{9x^2y^4}\to D\\\\=\left(3xy^2\right)^\frac{2}{3}=\left(3x\right)^\frac{2}{3}y^{2\cdot\frac{2}{3}}=\left(3x\right)^\frac{2}{3}y^\frac{4}{3}\to B\\\\\\Answer:C$

A company made a storage container with sheet steel walls. The container was in the shape of a rectangular prism, as shown below

nirvana33 [79]

The missing figure is attached

Answer:

The sheet steel costed $22.41 per square meter

Step-by-step explanation:

To find the cost per square units find the lateral area (they will made the walls only) of the rectangular prism and divide the cost of the steel sheet by it

The formula of the lateral area of the rectangular prism is:

LA = perimeter of base × height

∵ The length of the base is 9 m

∵ The width of the base is 5 m

∵ The height of the prism is 7 m

- Find the perimeter of the base

∵ Perimeter of base = 2(length + width)

- Substitute the values of the length and the width

∴ Perimeter of base = 2(9 + 5) = 28 m

Now use the formula of the lateral area to get it

∵ LA = 28 × 7

∴ LA = 196 m²
