Answer:

About 22 degrees

Step-by-step explanation:

Since we are given the opposite side measurement to the angle we wish to find and the hypotenuse measurement, we will want to use sine.

sin(theta)=3/8

theta=arcsin(3/8)

theta=22.024 approximately

Richie and bethany play basketball and practice shooting free throws after school. During one practice session, Richie attempted

mamaluj [8]

Answer:

Bethany did not do better than Richie because her average score was less than his.

Step-by-step explanation:

Average Value

The average or mean value of m successes out of n tries is given by:

$\displaystyle \bar x=\frac{m}{n}$

During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:

$\displaystyle \bar x=\frac{12}{15}=0.8$

Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:

$\displaystyle \bar x=\frac{8}{11}=0.72$

Bethany did not do better than Richie because her average score was less than his.

$3\frac15=3.2\\ 3\frac13=3.33333...$

$3.19, \ \ \ 3\frac15, \ \ \ 3.3, \ \ \ 3\frac13$

3.
$20\%\cdot1500\$=0.2\cdot1500\$=300\$$

4.
$\frac{600g}{3kg}=\frac{600g}{3000g}=\frac{600g}{5\cdot600g}=\frac15$
This fraction is $\frac15$

5.
$10^3+10^2+10+1=1000+100+10+1=1111$

6. $6.7\cdot5\$=33.5\$$

7.
$180-40\%\cdot180=180-0.4\cdot180=180-72=108$

8.
$9^2-4\cdot9=81-36=45$

from 8.45am to 12.45pm - 4 hours
$\$15\cdot4=\$60$
I earn $\$60$

10.
48 minutes = 1 hour - 12 min
21.15 - 1 hour = 20.15
20.15 + 12 min = 20.27

11.
$34.1^oC-27.6^oC=6.5^oC$

12.
$8\frac14 \ h= 8h \ 15min$
$10.30pm+8h = 6.30am\\ 6.30am+15min = \boxed{6.45am}$
I get up at 6.45am

13.
$12\cdot108=1296$

14.
$\overline{x}=\frac{8.2+9.4+3.5+2.9}4=\frac{24}4=6$

15.
$48\cdot26=1248 \ \ \ - \ \ \ total \ amount \ of \ lolipops \ in \ 48 \ bags\\ 1248\cdot20g=24960g = \boxed{24.96kg} \ \ \ - \ \ \ total \ weight \ of \ the \ 48 \ bags\\$
