Divide rs 350 in ratio 2:5​
mihalych1998 [28]

Answer:

100 : 250

Step-by-step explanation:

Sum the parts of the ratio, 2 + 5 = 7 parts

Divide the quantity by 7 to find the value of one part of the ratio.

350 ÷ 7 = 50 ← value of 1 part of the ratio, thus

2 parts = 2 × 50 = 100

5 parts = 5 × 50 = 250

350 = 100 : 250 in the ratio 2 : 5

Why did the women of Seneca Falls choose to echo the language in the Declaration of Independence? Write one sentence to explain
sveta [45]

Answer:

Step-by-step explanation:

The women of the Seneca Falls Convention choose to echo the language of the Declaration of Independence for multiple reasons including:

A) Evoke an emotional response- The Declaration of Independence is often referred to in important speeches as a way to remind Americans of the reasoning for why we became a free nation during the late 18th century.

B) Show that they deserve similar rights to men- The Declaration of Independence says that "all men" are created equal. The women of this convention changed that wording to say that all people are equally and deserve equal treatment in the eyes of the law.

A lake near the Arctic Circle is covered by a sheet of ice during the cold winter months. When spring arrives, the ice starts to
hichkok12 [17]

Answer: 1.5 meters


Step-by-step explanation:

Given: A lake near the Arctic Circle is covered by a sheet of ice during the cold winter months. S

S(t) models the ice sheet's thickness (in meters) as a function of time t (in weeks) S(t)=-0.25t+4

if we put x=0, then

S(0)=-0.25(0)+4\\=4\ meters

So 4 meters is the initial thickness

To find the thickness after 6 weeks, put x=6 we get

S(6)=-0.25(6)+4\\=-1.5+4=2.5\ meters

Decrease in thickness every 6 weeks= 4-2.5=1.5\ meters
