How do you solve b/3-1=4??

Mathematics

mezya [45]4 years ago

Alright! In order to solve this, you have to isolate your variable, which is b. To do that you'd first have to add one to both sides in order for you to be left with:

[b/3 = 5]

Since 3 is in the denominator, you multiply both sides by 3 in order to get rid of it. In the end you get 

[b = 15]

The answer is 15.

What is the range of g(x)=-4^x+2
d1i1m1o1n [39]

Answer:

R: {y<=2}

Step-by-step explanation:

We can identify the range by looking at all possible y values or the result after you input an x in the g(x) function. We see that in the g(x) function, the vertex of the quadratic graph lies on (0,2) when we graph it. Thus, any possible y value must be less than or equal to (0,2) because the slope is pointing down due to the negative coefficient attached to the x, making it have a maximum.

Thus all y values or the range of g(x) must be {y<=2}

The researchers used data from 10 trials so they could compare each trial or use the information in all, its better to use more than one so you can compare and see the difference.

A publisher estimates that 8 of every 50 books become national best sellers. What's percentage of the books do not become nation
ollegr [7]

Answer:

We conclude that 84% of books are not best-sellers.

Step-by-step explanation:

A publisher estimates that 8 of every 50 books become national best-sellers.

Means 16% of books are best sellers.

  • Because 16% of 50 books = 8    ∵ 16/100 × 50 =  8

Thus,

Bestseller books = 16%

Books that are not national best sellers = 100% -16% = 84%

Therefore, we conclude that 84% of books are not best-sellers.

Alberto wants to keep their favorite tree from being uprooted by heavy winds. They plan to tie 3 sections of rope to a band on t
motikmotik

Answer:

39 ft

Step-by-step explanation:

Using the description as a guideline I have drawn out the situation (badly drawn) as seen in the picture below. From the picture, we see that we need to find x which is the length of one of the ropes. Once we have this length we simply multiply it by 3 to find out how much rope we need altogether. Since this is the diagonal of a triangle we can use the Pythagorean theorem to solve for x.

Pythagorean theorem: a^{2} +b^{2}  = c^{2}  .... which a and b are the two sides while x is the diagonal.

5^{2} +12^{2} = x^{2}

25 + 144 = x^{2}

169 = x^{2} ... now we square root both sides

13 = x

Now that we have the length of one of the ropes we simply multiply this by 3 to find the total amount of rope needed.

13 * 3 = 39 ft
