Answer:

36 : 29

Step-by-step explanation:

Require to simplify the ratio

180 : 145

Divide both parts by 5

= 36 : 29 ← in simplest form

Simplest form means that no other number but 1 will divide into the 2 parts of the ratio.

WILL GIVE BRAINLIEST TO THE BEST CORRECT ANSWER!!!!!!! The people of Bridgetown wanted to build a bridge across a nearby river.

romanna [79]

Answer:

The width of the river is about 8.39 m.

Step-by-step explanation:

Tan = Opposite/Adjacent

The width of the river is the side of a right triangle opposite the angle of 40°. The 10 m distance is the length of the side adjacent to the measured angle. So, we have ...

tan(40°) = width/(10 m)

Multiplying by 10 m, we get ...

width = (10 m)tan(40°) ≈ 8.39 m

The width of the river is about 8.39 m.

Triss [41]

Answer:

Step-by-step explanation:

The midsegment AC is half the sum of the parallel bases, that is

AC = $\frac{DF+EB}{2}$ , then

x = $\frac{13+9}{2}$ = $\frac{22}{2}$ = 11 → D

If a =5, 0, −1,find a vector b such that compab = 2.b = _______.

Arturiano [62]

Answer:

$b = (q,r , 5q-2\sqrt{26} )$

Step-by-step explanation:

From the question we are told that

The vector given is

$a = (5,0,-1)$

Also $comp_a b = 2$

Generally

$comp_a b = \frac{a \cdot b}{|a|}$

Here $|a|$ is the magnitude of a which is mathematically represented as

$|a| = \sqrt{5^2 + 0^2 +(-1)^2 }$

=> $|a| = \sqrt{26}$

b is vector which we will assume to have the following parameters

$b = (q , r , x)$

$comp_a b = \frac{(5,0,-1) \cdot (q,r,x)}{\sqrt{26} } = 2$

=> $\frac{5q + 0 -x}{\sqrt{26} } = 2$

=> $x = 5q-2\sqrt{26}$

Hence the vector be can be mathematically represented as

$b = (q,r , 5q-2\sqrt{26} )$

This means that the vector b is more than one value since it is made up of variable

This means that if

$q = 1\\r=1\\x =1$

Then

$b = (1,1,5-2\sqrt{26} )$
