You have to multiply the eight pieces by 5 because it takes him five minutes to cut one piece of metal

Time=number of cuts times time it takes to make each cut

to cut something into 2 pieces, you need 1 cut
to cut into 3 pieces you need 2 cuts
therefor, to cut something into n pieces, it takes n-1 cuts
so 8piece is 8-1=7 cuts

time=number of cust times time per cut
time=7 times 5 minutes
times=35 minutes

Arada [10]

Answer:

E, F, B, and C

Step-by-step explanation:

Im just learning about these kind of things and this is a challenging question not going to lie.

I chose B because expanding and building more factories is apart of economics. You need more land to expand your business, but this will also affect the economy.

C seems like a good answer also because writing about economic trends is an important thing in economics. This also helps others learn out the economy and what not to do and what to do to help make our environment a better place.

I chose E because starting a business is apart of economics. A lot of business are apart of economic systems and help money come into our economy.

F is a good answer for me because the U.S government has been apart of America's economic system for a long time just like they are involved with everything else. The government is a big help and a big part of our economy, especially for america.

Step-by-step explanation:

Given system:

-x + y = 8
7x + 3y = - 16

Multiply the first equation by 7 and add up the equations:

-7x + 7y + 7x + 3y = 7*8 - 16
10y = 40
y = 4

How to find the distance from a velocity-time graph?

Orlov [11]

Answer:

Calculating the distance travelled

Calculate the total distance travelled by the object - its motion is represented by the velocity-time graph below.

Here, the distance travelled can be found by calculating the total area of the shaded sections below the line.

½ × base × height.

½ × 6 × 2 = 12 m 2

(10 – 6) × 2 = 8 m 2

We understand the points on the graph of h(x) to be ...

(0, 2), (1, 5), (2, 8), (3, 11), (4, 14), (5, 17)

The points on the graph of the inverse function will have the x- and y-coordinates reversed:

(2, 0), (5, 1), (8, 2), (11, 3), (14, 4), (17, 5)

The one that appears among the answer choices is ...
