Answer:

60 degrees

Step-by-step explanation:

On the diagram, we can see that the two angles have a dash on each of them. This means that they have the same measure.

So, if angle ABD is 60 degrees, then angle DBC would also be 60 degrees.

I hope this helps!

A hot air balloon is currently at a height of 900 feet. The balloon is descending by 10 feet minute. Find a function for the bal

mylen [45]

Answer:

$y=-10x+900$

Step-by-step explanation:

Let

x -----> the number of minutes

y ----> the balloon's height in feet

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have that

The slope is equal to

$m=-10\ \frac{ft}{min}$ ----> is negative because is a decreasing function

$b=900\ ft$

Remember that the y-intercept is the value of y when the value of x is equal to zero

In this context the y-intercept is the height of the balloon when the time is equal to zero (initial height)

substitute

$y=-10x+900$

12. An equation is shown. 8 1/2 - 3 1/? = 5 3/12<br>What is the value of the missing number?

weeeeeb [17]

Answer:

Step-by-step explanation:

Alright, lets get started.

$8\frac{1}{2}-3\frac{1}{?}=5\frac{3}{12}$

These are mixed number given.

Suppose the complete mixed number of second place is x.

Converting mixed numbers into fractions.

$\frac{17}{2}-x=\frac{63}{12}$

Adding x in both sides

$\frac{17}{2}=x+\frac{63}{12}$

$x=\frac{17}{2}-\frac{63}{12}$

Making common denominator

$x=\frac{102}{12}-\frac{63}{12}$

$x=\frac{39}{12}$

$x=\frac{13}{4}$

In mixed number form:

$x=3\frac{1}{4}$

So comparing with given equation, the '?' sign will be equal to 4.

Hence the answer is 4 : Answer

Hope it will help :)

Rose has 5 times as many stickers as John. They have 300 stickers in all. How many more stickers does Rose have than John? Show

kirill115 [55]

5x+x=300

6x=300

x=50

5(50)=250 (Rose)

x=50(John)

Rose has 250 stickers and John has 50, therefore Rose has 200 more stickers than John.
