Answer:

A 12

Step-by-step explanation:

We can use the pythagorean theorem to find the length a

a^2 + b^2 = c^2

a^2 + (4sqrt(3))^2 = (8sqrt(3))^2

a^2 +16*3 = 64*3

a^2 +48 = 192

Subtract 48 from each side

a^2 +48-48 = 192-48

a^2 =144

Taking the square root of each side

sqrt(a^2) = sqrt(144)

a = 12

We only take the positive square root because length must be positive

how do you solve this problem. there are approximately 2.1 million deaths per year in country A. Express this quantity as deaths

slamgirl [31]

Well... we know that... there are 365 days in a year, unless is a leap-year, but we'll use 365 anyway

and each day has 24hrs, each hr has 60 minutes

so. let us use those ratios

$\bf 2.1million\iff 2.1E6\iff 2,100,000\qquad thus
\\\\\\
\cfrac{2100000\ deaths}{1\ year}\cdot \cfrac{1\ year}{365\ day}\cdot \cfrac{1\ day}{24\ hr}\cdot \cfrac{1\ hr}{60\ minute}$

so.. multiply and simplify, cancelling out any like-units atop and bottom

notice, all we do, is use the ratios, in a way, that if we need one unit to be changed, we flip the ratio

for example, to toss away "year" unit, since in the first fraction is at the bottom, then we put it on the top on the ratio, year/year = 1, effectively cancelling the unit

PLEASE HELP ASAP

Lesechka [4]

Answer:

A. f and h

Step-by-step explanation:

For a linear function the First Differences of the y-values must be a constant. i.e. if we take the difference between any two consecutive y values or values of f(x) it should be the constant. For this rule to work, x values must change by the same number every time, which is true for all three given functions.

For function f:

The values of f(x) are: 5,8,11,14

We can see the difference in consecutive two values is a constant i.e. 3, so the First Difference is the same. Hence, function f is a linear function.

For function g:

The values of g(x) are: 8,4,16,32

We can see the difference among two consecutive values is not a constant. Since the first differences are not the same, this function is not a linear.

For function h:

The values of h(x) are: 28, 64, 100, 136

We can see the difference among two consecutive values is a constant i.e. 36. Therefore, function h is a linear function.

What is 13/6 as a mixed fraction

irina1246 [14]

Answer:

The answer is 2 1/6

Step-by-step explanation:

First you would divide 13 by six and that would leave you with 2 with a remainder of 1. Then you would put together the fraction leaving 6 as the denominator, 2 as the whole number, and 1 as the numerator.

Let me know if you need any other help!
