Mathematics

Sloan [31]3 years ago

Answer:

9

Step-by-step explanation:

3h + 18 + 15h = 180   ( adjacent angles add up to 180 degrees).

`18h = 180 - 18 = 162

h = 162 / 18 = 9 (answer)

Answer: h=9
3h° + 18° + 15h°=180°
18h+18=180
18h=180-18
18h=162°
h=162°/18
h=9

The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:
Montano1993 [528]

Answer:

0.2 miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.

Step-by-step explanation:

As there is no graph mentioned here but the information are quite sufficient to answer the question.

We have points (0,3), (5,4),(10,5)...

From these points we can find the slope of the line .

From point slope formula y-y_1=m(x-x_1)

And assigning (x,y) (0,3) and (x_1,y_1) (5,4)

m=\frac{y_1-y}{x_1-x} =\frac{4-3}{5-0} =\frac{1}{5}=0.2

This slope is also the speed of the bird which is 0.2\ miles\ per\ minute.

As by plugging the values of any coordinate point we can confirm this.

Lets put (10,5), y-axis is the distance so in 10 minutes the the distance covered by the bird must be equal to to y-axis value which is 5 miles.

y=0.2(x),y=0.2(10)=5\ miles

Now as in t=0 the bird has started from y-intercept value 3 so we can say that,the original distance of the bird from its nest is 3\ miles.

So the correct choices are:B and D

The birds speed is 0.2\ miles per minute and is 3\ miles away from its nest.

PLS ANSWER I WILL GIVE YOU BRAINLIST AND A THANK YOU!!
Arte-miy333 [17]

Answer:

x=45

Step-by-step explanation:

2x+45+x=180

Combine 2x and x to get 3x.

3x+45=180

Subtract 45 from both sides.

3x=180−45

Subtract 45 from 180 to get 135.

3x=135

Divide both sides by 3.

x=135/3

Divide 135 by 3

x=45

Simplify this question:
stiks02 [169]

Answer: 7n - 13

Step-by-step explanation:

Apply the distributive property.

4n + 3n + 3 ⋅ -5 + 2

Multiply 3 by -5

4n + 3n - 15 + 2

Add 4n and 3n

7n - 15 + 2

Add - 15 and 2

7n - 13

hope this helps :)
