Answer:

18/21

Step-by-step explanation:

7x3 = 21

6x3=18

Answer:

18

Step-by-step explanation:

[tex]\frac{6}{7} =\frac{x}{21} \\\\\frac{6}{7} =\frac{18}{21}[/tex]

Multiply 3 to 6 since 7 x 3 is 21,

so 6 x 3 = 18

Answer:

[tex]2\pi[/tex]

Step-by-step explanation:

first you take 60°/360°= 1/6   then you take 1/6 and multiple it by [tex]2\pi[/tex] and that equals [tex]\frac{\pi }{3}[/tex]   finally take  [tex]\frac{\pi }{3}[/tex]  times the radius (6) and that should equal [tex]2\pi[/tex]

The measure of the arc length associated with the angle is 2π inches OR 6.28 inches

From the question, we are to determine the measure of the arc length

The measure of the arc length can be calculated by using the formula,

[tex]l = \frac{\theta}{360 ^\circ}\times 2\pi r[/tex]

Where [tex]l[/tex] is the length of the arc

θ is the central angle

r is the radius of the circle

From the given information,

r = 6 inches

θ = 60°

Putting the parameters into the formula, we get

[tex]l = \frac{60 ^\circ}{360 ^\circ}\times 2 \pi \times 6[/tex]

[tex]l = \frac{1}{6}\times 2 \pi \times 6[/tex]

[tex]l =2\pi[/tex] inches OR 6.28 inches

Hence, the measure of the arc length associated with the angle is 2π inches OR 6.28 inches

Answer:

37.68

Step-by-step explanation:

Well, the first thing first is to know the outline of the question. So I made sure I knew the diameter. In this case we didn't, so I multipilied 6 by 2 and got 12. Then I multipyed 12 by 3.14 to get 37.68

Answer:

57 kilometers a day.

Step-by-step explanation:

I just divided 513 by 9 and got that.

Answer:

It increases it by 9.

Step-by-step explanation:

Given the following data;

Base = 4m

Height = 5m

Area of triangle = ½*base*height

Area of triangle = ½*4*5

Area of triangle = 2 * 5

Area of triangle = 10 m²

Multiplying the parameters by 3, we have;

Base = 4 * 3 = 12m

Height = 5 * 3 = 15m

To find the area of triangle;

Area of triangle = ½*base*height

Area of triangle = ½*12*15

Area of triangle = 6 * 15

Area of triangle = 90 m²

Therefore, multiplying the dimensions by a factor of 3 increases the area by 9.

Answer:

18

Step-by-step explanation:

90% of 20 is 18

Answer:

18

Step-by-step explanation:

90%of 20 =18

so the answer is 18

Answer:

[tex]-\frac{2}{25}[/tex]

Step-by-step explanation:

slope is the change in y over the change in x.

change in y is 14-18= -4

change in x is 30-(-20)= 50

so the answer is -4/50

we can factor out 2 from both equations to simplify the fraction. this gives us -2/25

Complete question :

Lamont wants to buy raspberries and apples to make a fruit tart raspberries cost $3.50 per pound and apples cost $3.75 per pound. How much dose he spend if he buys 3 pounds raspberry and 2 pounds of apples ?how much does he spend if he buys X pounds of raspberries and Y pounds of apples ? ​

Answer:

$18.00 ;

3.50x + 3.75y

Step-by-step explanation:

Given that:

Cost per pound of raspberry = $3.50

Cost per pound of apple = $3.75

Cost of 2 pounds of raspberry = 3 * $3.50 = $10.50

Cost of 2 pounds of apple = 2 * $3.75 = $7.50

Total spent = $(10.50 + 7.50) = $18.00

Cost of X pounds of raspberry and Y pound of apple

.

(3.50 * X) + (3.75 * Y)

3.50x + 3.75y

Answer:

if you see three consecutive numbers you can figure out that at least one of them is divisible by 6

Step-by-step explanation:

you can use mathematical induction by proving it mathematically. for a number to be divisible by 6, it should be divisible by 2. Since all are even numbers the number will be divisible by 2.
