Answer:

1/5 = q/p, or q:p

Step-by-step explanation:

You might want to rewrite 1/2p=2 1/2q as (1/2)p = (2 1/2)q.

To remove the fractions, multiply both sides by 2:

p = 2(2 1/2)q becomes p = 5q.

Dividing both sides by 5 yields p/5 = q.

Dividing both sides by p yields 1/5 = q/p, or q:p

Find the fraction of stundents enrolled in each language

blondinia [14]

Fraction of students enrolled in Chinese = $\frac{51}{126}$

Fraction of students enrolled in French = $\frac{33}{126}$

Fraction of students enrolled in Spanish = $\frac{42}{126}$

Solution:

Total number of students = 51 + 33 + 42

= 126

Number of students enrolled in Chinese = 51

Fraction of students enrolled in Chinese

$$=\frac{\text{Number of students enrolled in Chinese}}{\text{Total number of students}}$

$$=\frac{51}{126}$

Fraction of students enrolled in Chinese = $\frac{51}{126}$

Number of students enrolled in French = 33

Fraction of students enrolled in French

$$=\frac{\text{Number of students enrolled in French}}{\text{Total number of students}}$

$$=\frac{33}{126}$

Fraction of students enrolled in French = $\frac{33}{126}$

Number of students enrolled in Spanish = 42

Fraction of students enrolled in Spanish

$$=\frac{\text{Number of students enrolled in Spanish}}{\text{Total number of students}}$

$$=\frac{42}{126}$

Fraction of students enrolled in Spanish = $\frac{42}{126}$

If the length of AC equals 18, what is the length of the midsection DE

Free_Kalibri [48]

Answer:

The length of the midsegment is 9 ⇒ (B)

Step-by-step explanation:

In a triangle,

The midsegment is the segment which joining the midpoints of two opposite sides of it

The length of the midsegment is half the length of the third side in the triangle which opposite to it

<em>Let us use this rule to solve our question</em>

In Δ AC

∵ DE is the midsegment of it

∵ DE is opposite to the side AC

∴ The length of DE = 1/2 the length of AC

∵ The length of AC = 18

∴ The length of DE = 1/2 × 18

∴ The length of DE = 9

∴ The length of the midsegment is 9

The correct answer is B

How does depositon change the earths surface

jok3333 [9.3K]

Step-by-step explanation:

"Deposition occurs when weathered rocks, soil, and sediments are carried by erosion to a new location and left there. Deposition happens when the forces carrying the sediments - wind, water, glaciers - are no longer strong enough to move the sediments. Rivers and streams fill with melting snow in the springtime."

Jeffrey currently has an account balance of $1,565.00. His initial deposit on the account was $625 and it earned 4.7% simple int

hram777 [196]

A = P(1 + rt)

1565 = 625(1 + (0.047)(t))

2.504 = 1 + 0.047t

1.504 = 0.047t

t = 32

I hope this is correct! (Sorry I haven't done simple interest in a while.)
