Can anyone explain this question to me? My teacher solved it but I didn’t understand how she did it
Answers
Step-by-step explanation:
To find the space a figure takes, we need to find the volume. Volume of a rectangular prism can be found by multiplying the length, width, and height of the figure.
We can start with the green block. The dimensions of this figure are 6cm, 3cm, and 3cm. The 5cm at the bottom is not a dimension of the green figure. Instead, it shows the total width of both blocks. We will use this later.
Back to the first block, we will find its volume by multiplying its dimensions together.
3 · 3 · 6 = 54
So, the volume of the first block is 54 cm³.
To this, we will add the volume of the blue block. We can find its dimensions with some simple deduction.
The picture shows that the height of the figure is 4cm less than the height of the green one, 6cm.
6 - 4 = 2
The height, then, is 2cm.
The width can be found by subtracting the width of the green block from the total width of both figures, 5cm.
5 - 3 = 2
So, the width is also 2cm.
We can see that the length of the blue block is equal to that of the green one, so we know that the length is 3cm.
Now, multiply all the dimensions we have found together.
2 · 2 · 3 = 12
The volume of the blue block is 12cm³.
We have found the volumes of both figures, so now we can add them both together to find the total.
54 + 12 = 66
So, the total volume is 66cm³.
I hope this was a satisfactory explanation ^^ Good luck, mate

a. 40 miles
b. 540 miles
c. 480 miles
d. 600 miles
Answers
Answer:
c. 480 miles.
Step-by-step explanation:
From the graph:
after 5 hours distance travelled is 200 miles.
So by proportion distance in 12 hours = 200 * 12/ 5
= 2400/5
= 480 miles.

Answers
Answer:
You can tell if they are similar if all the angles correspond and the sides are all scaled down by the same factor. For instance, a triangle with sides of 30, 40, and 50 scaled down by a factor of 2 would have sides of 15, 20, and 25.

Answers
x= sin^-1(40/50)
x= 53.1301023542—>53.1 rounded to the nearest tenth
angle of elevation is 53.1
The angle of elevation of a kite is 53.13°
What is angle of elevation?"It is the angle formed by the line of sight and the horizontal plane for an object above the horizontal surface."
What is sine angle?"For a right triangle, the sine of acute angle [tex]\theta[/tex] is,
[tex]sin(\theta)=\frac{opposite ~side}{hypotenuse}[/tex]"
For given question,
Consider the following diagram for given question.
The length of the string (AC) = 50m
The kite is flying 40m vertically above the ground.
⇒AB = 40m
We need to find the angle of elevation [tex]\theta[/tex]
Consider the sine of angle [tex]\theta[/tex]
[tex]\Rightarrow sin(\theta)=\frac{AB}{AC} \\\\\Rightarrow sin(\theta)=\frac{40}{50}\\\\\Rightarrow sin(\theta)=0.8\\\\\Rightarrow \theta=sin^{-1}(0.8)\\\\\Rightarrow \theta=53.13^{\circ}[/tex]
Therefore, the angle of elevation of a kite is 53.13°
