Answer:

x=30.999=31

Step-by-step explanation:

Female students=17

Female students percentage=54.84%

Let the total students be x

Now we have,

54.84% of x=17

54.84x/100=17

54.84x=1700

x=1700/54.84

x=30.999=31

Answer:

there are 14 boys and 31 total students in chemistry class.

explanation:

total number of students: 100%

<u>total number of students: </u>

  • \frac{17}{54.84} * 100
  • 31 students total.

<u>Boys in the class:</u>

  • 100% - 54.84%
  • 45.16%

<u>Boys total:</u>

  • 31 * 45.16%
  • 14 boy students.

Segments
Ipatiy [6.2K]

There are several ways two triangles can be congruent.

  • \mathbf{AC = BD}<em> congruent by SAS</em>
  • \mathbf{\angle ABC \cong \angle BAD}<em> congruent by corresponding theorem</em>

In \mathbf{\triangle AOL} and \mathbf{\triangle BOK} (see attachment), we have the following observations

1.\ \mathbf{AO = DO} --- Because O is the midpoint of line segment AD

2.\ \mathbf{BO = CO} --- Because O is the midpoint of line segment BC

3.\ \mathbf{\angle AOB =\angle COD} ---- Because vertical angles are congruent

4.\ \mathbf{\angle AOC =\angle BOD} ---- Because vertical angles are congruent

Using the SAS (<em>side-angle-side</em>) postulate, we have:

\mathbf{AC = BD}

Using corresponding theorem,

\mathbf{\angle ABC \cong \angle BAD} ---- i.e. both triangles are congruent

The above congruence equation is true because:

  1. <em>2 sides of both triangles are congruent</em>
  2. <em>1 angle each of both triangles is equal</em>
  3. <em>Corresponding angles are equal</em>

See attachment

Hunter invested $750 in an account paying an interest rate of 6\tfrac{5}{8}6 8 5 ​ % compounded continuously. London invested $7
kompoz [17]

Answer: $ 55

Step-by-step explanation:

When interest is compounded continuously, the final amount will be

A=Pe^{rt}

When interest is compounded daily, the final amount will be

A=P(1+\dfrac{r}{365})^{365t}

, where P= Principal , r = rate of interest , t = time

For Hunter , P= $750, r = 6\dfrac{5}{8}\%=\dfrac{53}{8}\%=\dfrac{53}{800}=0.06625

t = 18 years

A=750e^{0.06625(18)}=\$2471.48

For London , P= $750, r = 6\dfrac{1}{2}\%=\dfrac{13}{2}\%=\neq \dfrac{13}{200}=0.065

t = 18 years

A=750(1+\dfrac{0.065}{365})^{18(365)}=\$2416.24

Difference = $ 2471.48 - $ 2416.24 =$ 55.24≈$ 55

Hence, Hunter would have $ 55 more than London in his account .
