Answer:

0.72 km per hour

Step-by-step explanation:

First, find the speed in meters per hour. Create a proportion where x is this speed:

[tex]\frac{36}{3}[/tex] = [tex]\frac{x}{60}[/tex]

3x = 2160

x = 720

So, the speed is 720 meters per hour. Convert this to kilometers per hour by dividing 720 by 1000, since there are 1000 meters in a kilometer:

720/1000

= 0.72

So, the speed of the conveyer belt is 0.72 km per hour

Answer:

Solution: means we replace 'x' with 'x+1' and we get g (x). Let us put x = 0 and then y = 0 to find two points on coordinate axis to easily plot the graph of g (x). Now, let us put y = 0 and find out x. So, second point is . Now, let us plot A and B then extend the line joining AB.

Answer:

C. 49, x-7

Step-by-step explanation:

(A+B)^2 = A^2 + 2AB + B^2

-14x = 2*A*B

where A=x

Therefore B=-7

and (x-7)^2=x^2-14x+49

Answer:

He paid Rs 1,850 to buy the watch

Profit = Rs 185

Step-by-step explanation:

Cost price = x

Profit = 10% of x

Selling price = Rs 2035

Profit = Selling price - cost price

10% of x = 2035 - x

0.1x = 2035 - x

0.1x + x = 2035

1.1x = 2035

x = 2035 / 1.1

x = 1,850

Cost price = x = Rs 1,850

Profit = 10% of x

= 10% of 1,850

= 0.1 × 1850

= 185

Profit = Rs 185

The x intercept is (8,0)

Step-by-step explanation:

To find the x intercept set y = 0 and solve for x

Y=3/4x - 6

0 =3/4x - 6

6 = 3/4x

4/3 *6 = 4/3*3/4x

8 =x

The x intercept is (8,0)

Answer:

8

Step-by-step explanation:

0 =3/4x - 6

6 = 3/4x

24 = 3x

x = 24/3 = 8

Answer:

C

Step-by-step explanation:

We are given that

[tex]\angle[/tex]DCB and [tex]\angle[/tex]CDA are supplementary.

We have to identify the parallel segments if [tex]\angle[/tex]DCB and [tex]\angle[/tex]CDA are supplementary.

Supplementary angles: If the angles are supplementary then the sum of two angles is 180 degrees.

Therefore,

[tex]\angle DCB+\angle CDA=180^{\circ}[/tex]

Therefore, angle DCB and angle CDA are interior angles .

Because CA is a transversal line and sum of interior angles is 180 degrees.

When the sum of interior angles formed between two lines  and on same side of transversal line is 180  degrees. Then the lines are parallel.

Therefore, angle DCB and angle CDA are formed between line AD and BC.

Hence, AD is parallel to BC.

Option C is correct.

Step-by-step explanation:

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true.

then it means if the events are independent then the probability is multiplying the probability of each event.

Solution: (1, 1)

Check:

y = -3x +4

1 = -3 +4

1 = 1

y = 3x -2

1 = 3 -2

1 = 1

Answer:

m=y2-y1/x2-x1 ⇒ m=-48+64/-15+21

m=16/6=8/3

y-y1/x-x1= m⇒ 8/3=y+64/x+21

Answer:

18

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp /adj

tan ? = 11/34

Taking the inverse tan of each side

tan ^-1 (tan ?) = tan ^-1 (11/34)

? =17.92791

To the nearest degrees

? = 18

Answer:

Set the measure of the indicated angle as x:

[tex]tan(x)=\frac{11}{34}\\\\x=tan^{-1}(\frac{11}{34})\\\\x=17.9279...[/tex]

Therefore, the measure of the indicated angle is around 18°

Answer: y-intercept of the function is (0,-2).

Answer:

56.52cm²

Step-by-step explanation

Lateral surface area = 2πrh

Given

r = 3cm

h = 3cm

Substitute

Lateral surface area = 2 * 3.14 * 3 * 3

Lateral surface area = 56.52cm²

Answer: 56.52

Step-by-step explanation: 3*3*3.14*2

Answer:

Step-by-step explanation:

All these amount of money are based on Dan's initial amount, which is x. Ben had 7 more than Dan, so Ben's amount of money is x + 7. Kaden has 4 more than Ben, so Kaden's amount of money is 4 + (x + 7) which is x + 11. So here's the breakdown so far:

Dan: x

Ben: x + 7

Kaden: x + 11

Now it looks like Kaden is the favorite and got another 20 from his mom, so his amount became x + 31. After Dan spends a dollar, making his amount x - 1, Kaden had 9 times what Dan had. Now we have finally:

x + 31 = 9(x - 1) and

x + 31 = 9x - 9 and

40 = 8x so

x = 5.

Dan originally had $5, Ben originally had $12, and Kaden originally had $16

Answer:

This would not be 20

Step-by-step explanation:

This question can be thought as a Pythagoras question.

By subtracting 2cm from both the left side ZW, and the right side YX, you will have a right angled triangle WYX (or ZYX, since after subtracting 2cm Z and W are essentially the same point)

I have attached a crude drawing of what the triangle is looking like, we are looking for the unknown value marked with the ?

Pythagoras states that [tex]a^{2} +b^{2} =c^{2}[/tex]

We are given the lengths 2cm and 20cm, which can be thought of as a (or b) and c. Substitute in the values 2 and 20 and solve for the unknown

Answer:

11/12 miles Lyon walk.

Step-by-step explanation:

3/4 -> 9/12

1/6 -> 2/12

9 + 2 = 11

The solution is :about  11/12 miles Lyon walk.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

given that,

Lyon walked 3/4 mile from school to the soccer field.

He then walked 1/6 mile home.

now, we have to find that,

About how many miles did Lyon walk

so, we need to add the both distance

i.e.  3/4 + 1/6

so, we have,

3/4 -> 9/12

1/6 -> 2/12

so, we get,

9 + 2 = 11

i.e. 3/4 + 1/6

= 9/12 + 2/12

=11/12

Hence, about  11/12 miles Lyon walk.
