liubo4ka [24]

Answer:

Step-by-step expThis is the concept of trigonometry, the value of x will be calculated as follows;

sin theta=[opposite]/[hypotenuse]

theta=x

opposite=16 units

hypotenuse=21 units

thus;

sin x=16/21

hence;

x=arcsin(16/21)

x=49.63

x=50 (to the nearest degrees)

Sophie [7]

Answer:

$318.17, out of state college is $161.12 cheaper per month

Step-by-step explanation:

72*24 = 1728 + 410*4 = 1728 + 1640 = 3368 + 450 = 18/12 = $318.17

8700+650*9 = 8700 + 5850 = 14550/9 = 1616.66

8500+400*9 = 8500 + 3600 = 12100 + 1000 = 13100/9 = 1455.56

1616.67 - 1455.56= $161.11 (use $161.12)

Step-by-step explanation:

we know that

To find out the average number of pounds, add the total number of pounds for each boy and then divide by the number of boys.

$\frac{(30+40+10+40)}{4}=\frac{120}{4}=30\ pounds$

therefore

The average number of pounds they bought was 30 pounds.

Evan borrowed money from his mom. If he paid her back 9.60 which is 20% of the total he owns, then how much did he owe her to be

lyudmila [28]

Given:

Evan paid his mom back 9.60 which is 20% of the total he owns.

To find:

How much did he owe her to begin with.

Solution:

Let x be the amount Evan owns.

According to the question,

20% of x = 9.60

$\dfrac{20}{100}x=9.60$

$\dfrac{1}{5}x=9.60$

Multiply both sides by 5.

$x=48$

Therefore, Evan owns 48 from his mom.
