Answer:
A. 9 Desserts
Step-by-step explanation:
We can make the equation 2/3x = 6 to find the answer
2/3x = 6 we need to isolate x so we divide by 2/3 on both sides
2/3 / 2/3 = 1 and 6 / 2/3
we divide 6 by 2/3 like 6/1 * 3/2 = 9
x = 9

The ratio of a to 5 equals b
What do we do here? Tell me in the comments, please!
The value of a for the ratio a:b = 5 will be 25.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio of a to 5 equals b. When b = 5 the value of 'a' will be calculated as below,
a / 5 = b
a / 5 = 5
a = 5 x 5
a = 25
Hence, the value of 'a' will be 25.

Abelie flew by plane from Dubai to Rome.
The flight time was 6 hours 42 minutes.
The average speed of the plane was 650 kilometres
per hour.
Work out the distance the plane flew.
Answer:
4355
Step-by-step explanation:
So first we will see how much is each hour
650 kilometres per hour.
So next we can work out how is 6 hours since that is easy.
650 X 6 = 3900
Next is the 42 mins
All you need to do is
650/ 60 = 65/6
65/6 X 42 = 455
Last step:
3900 + 455 = 4355
Done!
Hope I helped!
The distance is 4,355 km.
Given that,
The flight time was 6 hours 42 minutes. The average speed of the plane was 650 kilometres per hour.Based on the above information, the calculation is as follows:
We know that
[tex]Speed = Distance \div time \\\\Distance = Speed \times time[/tex]
Now for 6 hours, and 650 km/hr, the distance is 3,900
And, for 42 mins, and 650 km/hr the distance is [tex]650\div 60 \times 42[/tex] = 455
So, the total distance is
= 3,900 + 455
= 4,355 km

You jog 2 kilometers in 12 minutes. Your friend jogs 3 kilometers in 16.5 minutes. Who jogs faster? You jog faster. Your friend jogs faster. Question 2 How much sooner will the faster jogger finish a five-kilometer race?
Answer:
a) Who jogs faster?
Your friend jogs faster because he jogs with a speed of 10.91 km/hr
Step-by-step explanation:
Speed = Distance(km)/Time(hours)
Question 2 How much sooner will the faster jogger finish a five-kilometer race?
Your friend's will finish a 5km race at a speed of 18.18 km/hr
Your speed is :
You jog 2 kilometers in 12 minutes.
Convert 12 minutes to hours
60 minutes = 1 hour
12 minutes = x
x = 12/60
x = 1/5 hour
Your speed is calculated as:
2km/1/5hour
= 2 km ÷ 1/5 hour
= 2 × 5
= 10 km/hr
Your friend's speed is calculated as:
Your friend jogs 3 kilometers in 16.5 minutes.
Convert 16.5 minutes to hours
60 minutes = 1 hour
16.5 minutes = x
x = 16.5/60
x = 0.275 hour
Your speed is calculated as:
3km/0.275 hour
= 10.909090909 km/hr
Approximately = 10.91km/hr
a) Who jogs faster?
Your friend jogs faster because he jogs with a speed of 10.91 km/hr
Question 2 How much sooner will the faster jogger finish a five-kilometer race?
Your friend jogs faster, hence:
3 km = 10.91 km/hr
5km = x
x = 5 × 10.91/3
x = 18.183333333 km/hr
Your friend's will finish a 5km race at a speed of 18.18 km/hr

In the figure above,AD intersects BE at C. If x=100 , what is the value of y?
A) 100
B) 60
C) 90
D) 80
Answer:
The answer is D), 80.
Step-by-step explanation:
All sides of a triangle must add up to 180°. So, if x = 100, angle BCA must equal 60° because 180 - 120 = 60. Since angles BCA and DCE are vertical angles, they are equal, making angles DCE 60°. All you need to do now is add up 60 + 40; that should give you 100. You also need to subtract that from 180 to get your final answer of y = 80°.
The solution is Option D.
The value of y from the two triangles is given by the equation y = 80°
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the first triangle be represented as ABC
Now , let the second triangle be represented as CDE
Now ,
The measure of angle x = 100°
The measure of ∠ACB = measure of ∠DCE ( vertically opposite angles )
And , for a triangle ∠A + ∠B + ∠C = 180°
So , The measure of ∠ACB = 180° - ( x° + 20° )
And , the measure of ∠DCE = 180° - ( y° + 40° )
Substituting the values in the equation , we get
180° - ( x° + 20° ) = 180° - ( y° + 40° )
when x = 100°
Subtracting 180° on both sides of the equation , we get
- ( x° + 20° ) = - ( y° + 40° )
( 100° + 20 ) = ( y° + 40° )
( y° + 40° ) = 120°
Subtracting 40° on both sides of the equation , we get
y = 80°
Hence , the measure of angle ∠y = 80°
