Use complete sentences to describe the relationship between the two sets A and B if A ⊆ B .

kakasveta [241]

Answer:

The relationship between the two sets A and B if A ⊆ B is A is subset of B

Solution:

A is subset of B means,” all elements of set A are present in set B”

Consider two sets A and B where ,

A = {1,2,3,4,5}

B = {1,2,3,4,5,6,7,8}

All Elements of set A {1,2,3,4,5} are present in set B

hence we relate set A and set B as A ⊆ B,which means set A is subset of set B. Symbol “⊆” is used to denote subset

So set A is subset of set B (A ⊆ B)

A plane has traveled 26 miles on a course heading 48º east of north. How far north (x) has the plane traveled at this point, to

GrogVix [38]

Answer: $17.4\ \text{miles}$

Step-by-step explanation:

Given

A plane has traveled 26 miles on a course heading $48^{\circ}$ east of north

Taking the component of travel in North direction

The distance traveled in North is given by with the help of figure

$\Rightarrow x=26\cos 48^{\circ}\\\\\Rightarrow x=26\times 0.669\\\\\Rightarrow x=17.4\ \text{miles}$

Put 50%, 2/25, 5, and 0.31 in order from greatest to least

storchak [24]

Answer:

$5,50\%,0.31,\frac{2}{25}$

Step-by-step explanation:

we have

50%, 2/25, 5, and 0.31

1) 50%

we know that

$50\%=\frac{50}{100}$

2) 2/25

Multiply by 4/4

$\frac{4}{4}(\frac{2}{25})=\frac{8}{100}$

3) 5

Multiply by 100/100

$\frac{100}{100}(5)=\frac{500}{100}$

4) 0.31

Multiply by 100/100

$\frac{100}{100}(0.31)=\frac{31}{100}$

Now all numbers have the same denominator

$\frac{500}{100}> \frac{50}{100}>\frac{31}{100}>\frac{8}{100}$

therefore

$5 > 50\%>0.31>\frac{2}{25}$

$5,50\%,0.31,\frac{2}{25}$
