Traveling $m$ miles on this taxi costs

$c=2.5+3.25m$

In fact, we spend 2.50 no matter what, and then we add 3.25 (i.e. the cost of a mile) multiplied by the number of miles.

This quantity has to be less than or equal to 61, so we have

$2.5+3.25m\leq 61$

Solving for $m$ , we start by subtracting 2.5 from both sides:

$3.25m\leq 58.5$

Then, we divide both sides by 3.25:

$m\leq 18$

Ella collects 50 bottles to recycle.Of the bottle she collects 19 are plastic and the rest are glass.What percent of the bottles

gulaghasi [49]

Glass bottles =total number of bottles - numeber of bottle of plastic
gass bottles=50-19=31 bottles of glass.

percent of the bottles are glass=(number of bottles of glass*100%) / total number of bottles.

percent of the glass bottles=(31 bottles * 100%) / 50 bottles=62%

Answer: the percent of the bottles of glas is 62%

The value of the missing length is 20

Let the missing length be x

From Parallel lines and transversal theorem, we have that

If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.

Then, we can write that

$\frac{x}{15} =\frac{16}{12}$

∴ $x = \frac{15\times 16}{12}$

x = 20

Hence, the value of the missing length is 20

If Log 20 = 1.301 what is the value of Logsub100 20?

Charra [1.4K]

Answer:

$log_{100}20 = 0.6505$

Step-by-step explanation:

log20 = 1.301 (when you see only "log" with no base, it is taken as a base 10)

This basically means:

$10^{1.301} = 20$ (This is the log in exponential form)

Since we don't know what $log_{100}20$ is equal to, we will say $log_{100}20$ = x

So to solve for $log_{100}20$ = x, you do the same thing. (convert to exponential form)

$100^{x} =20$

Now you will notice that both of these equations are equal to 20.

Since 20 = 20,

we can say $100^{x}$ = $10^{1.301}$

Another way of saying 100, is $10^{2}$ (make the bases the same)

Now we get $10^{2x} = 10^{1.301}$

(we get 2x because an exponent to the power of an exponent ( $2^{x}$ ) is the same as 2 * x)

Because you have the same base, you can just ignore the 10s and focus on the exponents. So you get:

2x = 1.301

x = 0.6505

PLZ HELP I WILL GIVE BRAINLIEST

Kipish [7]

Answer:

the third one

Step-by-step explanation:

bc like there are 2 boxes of 1 and 5 boxes of 1/6 so thats already 2 and 5/6 which applies to all of them. then there is 1 box of 1 and 2 boxes of 1/3 so thats 1 and 1/3 which applies to all of them also but when you make them have the same denominator you get 2 and 5/6 + 1 and 4/6 which deletes the second one. When you add you should get the same denominator so that deletes the first one so then you simplify that and the fraction should still be equal to the unsimplified fraction so you should get 4 and 1/2 if that makes sense
