Answer:
2,268.63
Step-by-step explanation: there are two methods.
1st you can multiply 58.17 by 39.
or the 2nd way is the fish method.
fish method: _/39 and 58.17/1
the 39 and 1 are the hours
the blank and 58.17 are the money
you would multiply 58.17 by 39 and divide by 1.

Answer:
80.38°
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
The person is standing 40 ft from the building. The point they're looking at is 236 ft above their eyes. So the angle α is found from ...
tan(α) = 236/40
α = arctan(236/40) ≈ 80.38°
There are 152 men, 76 women and 38 children.
Step-by-step explanation:
Total persons = 266
Let,
men = m
women = w
children = c
According to given statement;
m+w+c=266 Eqn 1
m = 4c Eqn 2
w = 2c Eqn 3
Putting value of m and w from Eqn 2 and 3 in Eqn 1
Dividing both sides by 7
Putting c=38 in Eqn 2;
Putting c=38 in Eqn 1;
There are 152 men, 76 women and 38 children.

1) "
Rename one-eight as a percent".
→
= 1 ÷ 8 = 0.125 ;
→
= 0.125 ;
→ x = 0.125 * 100 = {move the decimal point in the number, "0.125"; two spaces forward, since we are MULTIPLYING, by "100" (which has 2 zeros);
→ x = 12 * 100 = 12.5 .
So: →
= 12.5 % ; since "12.5 % = 12.5/100 "
_____________________________________Other method:

→ x = 100 *

→ x =

→ x = 12.5 ;
→
=
= 12.5% ;
→ 12.5 % =
;
= ?
→ {Take the "12.5" & move the decimal backward TWO (2) places, since we are "dividing" by "100" (which has 2 "zeros") ;
= 0.125 =
=
.
_________________________________________________2) "
Rename "0.709" as a percent."
===>
= 0.709 ;
→ x = 0.709 * 100 = ? ;
Note: Take the "0.709" ; & move the decimal place "2 (TWO)" spaces forward, since are MULTIPLYING by "100" (which has 2 zeros); to get:
→ x = 70.9 ;
→ x = 0.709 * 100 = 70.9 ;
→
=
=
70.9% ;
→ which is: Answer choice: [B] .
→ 70.9% =
= ? ;
{take the "70.9" ; and move the decimal point backwards TWO (2) decimal places; since we are DIVIDING by "100" (which has "2 (two) zeros") ;
→ 70.9% =
= 0.709 .

or, write as: 66.666666....% ; or, round to:
