<span>14100000 written in scientific notation would be 1.41 x 10^7 because you have to make the number be between 1 and 10, so you would put your decimal between the 1 and 4, then you would count the number of zeros in standard form, then you would solve and your answer would be 1.41 x 10^7</span>

It's 1.41 times 10^7 because there are 7 digits after the first one

Answer:

25% increase

Step-by-step explanation:

length is 24 inches after the increase and width is 33 inches (i did length as up and down and width as side to side, that's how I always do it but I might be wrong let me know and I can fix it)

the area before it gets increased it 600

after the increase its 792

and 600 is 75.75% of 792

so it would be 25.25% increase

This person did something wrong and I do not know what it is :( Please help this is for points!

Arlecino [84]

Answer:

0.4 cm

Step-by-step explanation:

The magnifying glass basically zooms into smaller objects. If the insect appears to be 2cm, then it is actually smaller than this. It cannot be 10 cm.

If the scale factor is 5, then this means that the insect is zoomed in 5 times through the magnifying glass. Use the following ratio:

$\frac{2}{5}$

This fraction can also be seen as division, so:

$2$ ÷ $5=0.4$

The insect is actually 0.4 cm long.

(or 4 millimeters)

Which of the following intervals represents the set (1,4) u [2,6]?

fenix001 [56]

Set is a sum of two intervals :(1,4) u [2,6]
In the first interval it is open on both sides so 1 and 4 don't belong to this interval, the second is closed so both 2 and 6 belong to interval and numbers between 2 and 6
We can write it as 1<x $\leq 6$
summing both sets we have one set: (1,6]
so
a) represent our set
b) also represent because all numbers between 4-6 and 6 are in our set
c)also represent, all numbers are in main set
d)also represent

The value of y when x=5

Molodets [167]

D. 35 is the answer. Since we know that 14=2k based on the knowledge given in the first part of the equation, we can solve for K. We learn that K=7. Then, we can substitute K into the second equation: y=(7)(5) which is 35.
