Answer: The arc length of the clock is 31.42cm

Step-by-step explanation:

1. Use your section formula: S = r (Radius) θ (Theta: Angle in radians)

2. Convert your 180 degrees to radians by multiplying it by π / 180, resulting in π radians.

3. Take your radius of 10cms and multiply it by π, leaving 31.42cm. This is the length of the 180 degree arc.

the question measures 6.EE.7 because it asks the student to solve a real-world problem by writing an equation of the form px=qpx=qpx=q for a case in which p,qp,qp,q and x are all non-negative rational numbers. In this case the equation includes a division expression and shows the total cost of $13.50\$ 13.50$13.50 divided by 666, the number of spiral notebooks.

Answer:

20 or 18

Step-by-step explanation:

The value of x is 10.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

From the triangle it can be assume that ΔPSR is similar to ΔPQR.

Then, the ratio of corresponding sides of triangles are proportion.

So, PQ/ PS = QR/ RS

9/15 = 6 /x

9x = 90

x= 90/9

x= 10

Thus, the value of x is 10.

Answer:

The coordinates of the midpoint between the two

points is (-1,4)

Step-by-step explanation:

Here, we want to find the midpoint between the two given points

To do this, we are to use the midpoint formula

We have this as;

m = (x1 + x2)/2, (y1 + y2)/2

(x1,y1) = (-7,9)

(x2,y2) = (5,-1)

(x,y) = (-7 + 5)/2, (9-1)/2

= (-2/2, 8/2) = (-1,4)

Answer:

2.75feet

Step-by-step explanation:

Given data

Volume= 11.39 cubic feet

Length= 2.3 feet

Width= 1.8 feet

Depth= ???

The expression for the volume is  

Volume= Length*Width*depth

11.39=2.3*1.8*d

11.39=4.14d

d= 11.39/4.14

d= 2.75

Hence the depth is 2.75feet

Answer:

3

Step-by-step explanation:

Given the function : y = x/3 + 1

If an input value, x is given as 6 ;

Output value, y can be obtained by Substituting the value x = 6 into the function and calculating the value of y

Calculation goes thus ;

y = 6/3 + 1

y = 2 + 1

y = 3

Output, y = 3

Given:

I have walked 20% of the way to school.

I have 1200 metres more to walk than when I have 20% of the walk remaining.

To find:

The distance from home to school.

Solution:

Let x be the distance from home to school.

I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.

It means 1200 is [tex]100\%-20\%-20\%=60\%[/tex] of the total distance from home to school.

[tex]1200=\dfrac{60}{100}x[/tex]

[tex]1200=0.6x[/tex]

[tex]\dfrac{1200}{0.6}=x[/tex]

[tex]2000=x[/tex]

Therefore, the distance from home to school is 2000  metres.

How far, in metres, is it from my home to my school is 2,000 metres.

First step is to formulate

1200/(1-2×20%)

Second step is to find how far in metres

Distance=1200/(1-0.4)

Distance=1200/0.6

Distance=2,000

Inconclusion how far, in metres, is it from my home to my school is 2,000 metres.

Answer:

x=3

x=−3

Step-by-step explanation:

2x^2 - 5 = 13

Subtract 13 from both sides.

2x^2 - 5 - 13 = 0

Subtract 13 from −5 to get −18.

2x^2 - 18 = 0

Divide both sides by 2.

x^2 - 9 = 0

Consider x^2−9. Rewrite x^2−9 as x^2−3^2. The difference of squares can be factored using the rule: a^2−b^2=(a−b)(a+b).

Answer:

The population mean = sample mean = x`= 67.5

Population standard deviation = 13.369

Sample standard deviation= 4.225

Step-by-step explanation:

AS the population mean is not given we will calculate it from the sample.

The mean of the sampling distribution is equal to the population mean .

The sample mean is calculated by

x`= ∑x/n= 75,+ 62, +69,+65,+66,+64, +67,+70,+74 + 63/10

x`=675/10= 67.5

The standard deviation of the sample is equal to

u = σ/ √n   where σ is the population standard deviation and n is the number of observations.

Calculating the sample mean

s= √∑xi²/n- (∑x/n)²

s= √(45741/10)- (675/10)²

s= 4.2249

σ= u*√n= 4.229 *√10

σ=13.360

Answer:

I think the answer is 5.75 miles.

Step-by-step explanation:

If the drone flies 2,530 ft in 5 seconds, that means that in one minute it flies 30,360 ft. And 30,360 divided by 5,280 is 5.75.

There are 5.74 miles does the drone fly in a minute.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Ashley flies a drone 2,530 ft in 5 s.

Now,

Since, Ashley flies a drone 2,530 ft in 5 s.

We know that;

1 minute = 60 seconds

Hence, Number of miles in 1 minutes = 2530/5 × 60

                                                          = 30,360 ft

Since, We know that;

1 ft = 0.000189 miles

Hence, we get;

⇒ 30360 × 0.000189

⇒ 5.74 miles
