The diameters of two circles are in the ratio 2 5
The area of the larger circle is 450 cm?
Work out the area of the smaller circle
Answer:
180
Step-by-step explanation:
2:5
? : 450
5u-> 450
1u->90
2u-> 180
Answer:
72 cm²
Step-by-step explanation:
Given the ratio of diameters = a : b , then
ratio of areas = a² : b²
Here the ratio of diameters = 2 : 5 , then
ratio of areas = 2² : 5² = 4 : 25
let x be the area of smaller circle then using proportion
[tex]\frac{25}{450}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )
25x = 1800 ( divide by 25 )
x = 72
That is the area of the smaller circle is 72 cm²

Find the value of x in the triangle shown below.
56°

4.5

Step-by-step explanation:
[tex] \frac{ \sin(56) }{4} = \frac{ \sin(x) }{4.5} \\ \sin(x ) = \frac{4.5 \times \sin(56) }{4} = \frac{3.73}{4} \\ \sin(x) = 0.9326 \\ x = 68.84[/tex]
Hence, the value of x is 68.84 degrees.
What is an angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs, and sometimes the arms of the angle.
How to solve?we know sine rule,
[tex]\frac{sin(56)}{4} = \frac{sin(x)}{4.5}[/tex]
sin(x) = [tex]\frac{(4.5).sin(56)}{4}[/tex] = [tex]\frac{3.73}{4}[/tex]
sin(x) = 0.9326
x = 68.84

You need to download 3 games for your math class. Each game is the same price. Since this is your first time downloading a game from the site, you are also charged a one-time $0.50 access fee. You are charged a total of $4.35. What is the cost of each game? Show your work and round your answer to the nearest cent.
Answer:
Each game costs $1.28.
Step-by-step explanation:
First, we need to find the total of all the games.
Since the only additive is the $0.50, we simply subtract it from the total.
4.35-0.50=$3.85
Since you bought three games, and they're all the same price, we divide $3.85 by 3.
3.85/3=1.2833333
Since were doing it by pennies, we can round it down to $1.28 per game.
Hope this helps!
Answer:
$1.28 per game.

Help me find the value of k asap please!
5/4(2 - k) = 2(3k - 1) - 2/3k
9514 1404 393
Answer:
k = 54/79
Step-by-step explanation:
You can eliminate fractions by multiplying both sides by 12.
15(2 -k) = 24(3k -1) -8k
30 -15k = 72k -24 -8k
54 = 79k
54/79 = k

Step-by-step explanation:
The speed of the train is 320 miles per hour.
What is speed?Speed is the ratio of the given distance and time.
It shows how fast an object is moving at a given time.
The formula is Distance / Time.
We can find the distance or time when the required values is given using this formula.
We have,
The speed of the TGV train can be calculated using the formula:
Speed = distance/time
where distance is given in miles and time is given in hours.
In this case,
The distance traveled by train is 800 miles, and the time taken to travel this distance is 2.5 hours.
Substituting these values into the formula, we get:
Speed = 800 miles / 2.5 hours
Simplifying the expression on the right-hand side, we get.
Speed = 320 miles per hour
Therefore,
The speed is 320 miles per hour.
