Answer:
The change in height is 6/10 miles per hour and the entire descent will last 150 minutes (2 hours and 30 minutes)
Step-by-step explanation:
The gilder started 1 1/2 miles above the ground, in other words, it started [tex]\frac{15}{10}[/tex] miles above the ground. After 60 minutes it is now [tex]\frac{9}{10}[/tex] miles above the ground.
Therefore, the change in height in one hour is: [tex]\frac{15}{10}-\frac{9}{10}= \frac{6}{10}[/tex] miles.
Now, we know that the glide descends at a rate of 6/10 miles per hour, we can solve the second part of the problem using the rule of three (or proportions)
If it takes it 60 minutes to descend 6/10 miles, how long it will take it to descend 15/10 miles?
60 minutes --- 6/10= .6
x minutes ---- 15/10= 1.5
Therefore [tex]x=\frac{60(1.5)}{.6} =\frac{90}{0.6} =150[/tex] minutes
Thus, the entire descent will last 150 minutes.

At the end of a pizza party of a cheese pizza and of a pepperoni pizza were left. Brad ate
of all the leftover pizza. What fractional part of a whole pizza did Brad eat?
1
Answer:
The fractional part of a whole pizza did Brad ate is:
[tex]C=\frac{x}{X}\\P=\frac{y}{Y}[/tex]
Step-by-step explanation:
Suppose x portion of the cheese pizza and y portion of a pepperoni pizza were left.
Consider the whole of a cheese pizza as X and the whole of a pepperoni pizza as Y.
Then the fractional part of a whole pizza did Brad ate is:
[tex]C=\frac{x}{X}\\P=\frac{y}{Y}[/tex]

If the measure of angle ABD and DBC are a linear pair, with a measure of angle ABD = (5x+29) and measure of angle DBC=(2x+32),what is the value of x?
Answer:
x = 17
Step-by-step explanation:
5x + 29 + 2x + 32 = 180 (linear pair means that these angles add up to 180 cos they are in a line)

Help me with number 4 plzzzzzz
Answer: x=8
Step-by-step explanation:
To solve for x, we want to use our algebraic properties to isolate x.
[tex]-\frac{1}{2}x-7=-11[/tex] [add both sides by 7]
[tex]-\frac{1}{2}x=-4[/tex] [multiply both sides by -2]
[tex]x=8[/tex]
Now, we know that x=8.

Which part of the angle is the vertex?
A. AB
B. Point A
C. AC
D. Point C
Answer:
Point A
Step-by-step explanation:
The vertex is where the two rays meet together
A is the vertex
The vertex of the angle is the shared endpoint of the two rays [tex]\underset{AB}{\rightarrow}[/tex] and [tex]\underset{AC}{\rightarrow}[/tex], that is, the vertex is at Point A. Hence, option B is the right choice.
What is a ray?A ray is made up of a half-line and its endpoint.
If a ray has an endpoint A and a B that is any other half-line point, then the ray is represented by [tex]\underset{AB}{\rightarrow}[/tex].
What is an angle?A pair of rays with a shared endpoint form an angle.
The rays are referred to as the angle's sides.
The shared endpoint is referred to as the angle's vertex.
How do we solve the given question?We are asked to identify the vertex of the given anis
The given angle is made of the rays [tex]\underset{AB}{\rightarrow}[/tex] and [tex]\underset{AC}{\rightarrow}[/tex], the shared endpoint is at Point A.
As we know, the shared endpoint is the vertex of the angle, so Point A is the vertex of the given angle. Hence, Option B is the right choice.

Answer:
24
Step-by-step explanation:
i just took the test :)
The degree of rotation will be equal to 24°.
It is given that we have a regular 15 sided polygon.
We need to find out the degree of rotation for it.
What is the formula to determine degree of rotation ?
The formula of degree of rotation is given by Degree of rotation = 360° / Number of sides.
As per the question ;
We have a regular 15 sided polygon.
or
No. of sides of regular polygon = 15
We know that ;
Degree of rotation = 360° / Number of sides
⇒ Degree of rotation will be equal to ;

A volcanic eruption releasing rock, ash, and dust particles into the air is an example of which interaction?
the biosphere interacting with the geosphere
the geosphere interacting with the atmosphere
the geosphere interacting with the hydrosphere
the hydrosphere interacting with the atmosphere
The interaction described is that of the geosphere interacting with the atmosphere.
The geosphere refers to all the rock and mineral materials that we have on our planet including:
Lava in the mantle Soil Mountains and everything made of rockThe atmosphere is the air that surrounds the Earth including gases like Nitrogen and Oxygen.
When a volcano erupts therefore, it is releasing rock (geosphere) into the air (atmosphere).
As a result, we can conclude that a volcano erupting is an interaction between the geosphere and the atmosphere.
