Answer:

m∠A+m∠B = m∠ACD.

m∠A = 56°

m∠B = 97°

Step-by-step explanation:

In this problem, we are given that m∠B is fifteen less than twice the m∠A.

Let m∠A = x°

This means that m∠B = 2x°-15°

Due the exterior angles theorem,

m∠A+m∠B = m∠ACD.

Since we are given that m∠ACD is 153°,

m∠A+m∠B=153°.

x+2x-15=153

x=56°

That means

m∠A = 56°

m∠B = 2(56) -15

m∠B = 97°

The value of a for the ratio a:b = 5 will be 25.

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.

Step-by-step explanation:

Given

w = weight

a = age

Required

Represent the weight as a function of age

When writing a function.

[tex]y = f(x)[/tex]

means that y is a function of x

Using the above to answer the given question, we have:

[tex]w = Q(a)[/tex]

Which means w is a function of a

and can be rewritten as:

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

THE ANSWER IS 6

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,

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

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°

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°
