$\bf \textit{exponential form of a logarithm}\\\\
log_{{ a}}{{ b}}=y \implies {{ a}}^y={{ b}}\qquad\qquad 
% exponential notation 2nd form
{{ a}}^y={{ b}}\implies log_{{ a}}{{ b}}=y \\\\
-------------------------------\\\\
e^a=47.38\implies log_e(47.38)=a\implies ln(47.38)=a$

Step-by-step explanation:

Answer 19:-

2x + 10 = 20

2x = 10

x = 5

Answer 20:-

80 + 20x = 300

Sabrina rode on a Ferris wheel at the state fair. The radius of the Ferris wheel was 106 feet. What is the approximate distance

Setler [38]

9514 1404 393

Answer:

666 ft

Step-by-step explanation:

The circumference of the wheel is given by the formula ...

C = 2πr

For a radius of 106 ft, the circumference is ...

C = 2(3.14)(106 ft) = 665.68 ft

Sabrina traveled about 666 feet in one revolution.

How many solutions does the equation have?

Alexxx [7]

-6 + 6 = 0 0 + -2x = 12 + 6 -2x = 12 + 64x+2(x-3)=8x+12 is our main problem right? so...
4x + (-3 * 2 + x * 2) = 8x + 12
4x + (-6 + 2x) = 8x + 12
So next we do:
-6 + 4x + 2x = 8x + 12
Reorder the terms :) -6 + 6x = 12 + 8x
Now were going to solve for x
-6 + -2x = 12 + 8x + -8x
8x + -8x = 0
-6 + -2x = 12 + 0
-6 + -2x = 12
-6 + 6 = 0
0 + -2x = 12 + 6
-2x = 12 + 6=
-2x = 18
so now were just going to divide each side by -2
and so thats going to be like this
-2x = 18
/ -2 /-2
0 -9
so whats left over is x = -9
So your answer is A.

Ms. Adler bought x bags of

OLga [1]

Answer:

Step-by-step explanation:

Number of bags = Total money spent / Cost of each bag

x = number of bags of chips

Simply divide 17.50 by 1.25 to work out how many bags of chips he can purchase.

Number of bags = Total money spent / Cost of each bag

$x = \frac{17.50}{1.25}$ = ?

based only on the information given in the diagram which congruence theorems or postulates could be given as reason why ABC=DEF

oksian1 [2.3K]

Answer:

SAS

SSS

Step-by-step explanation:

Since these are right triangles, and you have the two hypotenuses are congruent to each other and two legs that are also congruent to each other, then HL can be applied.

For HA to work we must have been given something else about one of those angle (besides the 90 degree one).

Since you have two corresponding sides that are congruent, then the 90 degree angles in both are congruent, and then the sides right after that 90 degree angle are also congruent to each other, so SAS can be applied.

We can't use AAS. We only know something about one angle per each triangle due to the markers.

LA? Needed another angle besides the 90 degree one.

All three corresponding sides are congruent. The markers tell us this. So we can apply SSS.
