What is the answer to this question?

Step-by-step explanation:

by using the formula of circumference with diameter pie ×diameter

Answer:

ω= 0.01 rad/s

Step-by-step explanation:

The given data is question is ,

Firstly let's find the linear speed. Which is

=> v = Circumference/time

=> v = 2πr/180s

=> v = 3.14 × 100ft ./ 90

=> v = 3.48 ft/s ≈ 1m/s

=> v = r[tex]\omega[/tex]

=> [tex]\omega[/tex] = v/r

=> [tex]\omega[/tex] = 1/100

=> [tex]\omega[/tex] = 0.01 rad/s

Answer:

Grapes are less expensive

Step-by-step explanation:

First, find how much money 1 pound of each fruit is:

Bananas: $1.47 / 3 = $0.49

Grapes: $1.18 / 2 = $0.59

Compare:

0.49 < 0.59

So grapes are less expensive

Answer:

Use the slope formula and slope-intercept form  y = mx + b to find the equation you get:

y = 8x

If thats not what your looking for then for every 1 (x) you get 8 (y)

Answer:

3.2 hours

Step-by-step explanation:

48x4=192

192 divided by 60 is 3.2

Answer:

3 hours and 12 minutes

Step-by-step explanation:

there are 15 sets of 4 in one hour, so 15 plus 15 equals 2 hours or 30 braids. Then you add one more hour and you get 45 braids and then for the last three braids its 12 minutes

Answer: The probability of you drawing a dime is 0.24

Step-by-step explanation:

5 quarters, 6 dimes, 2 nickels, 12 pennies

5+6+2+12= 25

6/25= 0.24 or 24%

Answer:

0.24

Step-by-step explanation:

P(dime) = 6/25 which is 0.24

Answer:

Equation:y = 1/2x .  or x = 2y

Constant = 2

Step-by-step explanation:

Input y = output x

the first input/output says that when inputed 2, the number 1 is outputted.

Similarly, when 5 is inputted, 2.5 is the output.

1/2 = 2.5/5

That means that y = 1/2 x

or x = 2y

Answer:

x + 2y - 5 = 0

Step-by-step explanation:

We can see that , the graph passes through (0,2.5) and (5,0) . Therefore the ,

We can use the intercept form of equation as ,

=> x/a + y/b = 1

=> x/5 + y/2.5 = 1

=> x + 2y/5 = 1

=> x + 2y = 5

=> x + 2y -5 = 0 .

This equation can be verified by plotting the graph .[ Refer to attachment ]

Answer:

15

Step-by-step explanation:

30% is equal to 0.3 as a proportion

Multiply 50 by 0.3 to get the number of students who play soccer.

50 X 0.3 = 15

Answer:

15

Step-by-step explanation:

football and track =50% =25 students

20% of 50 is =10 students then 25 +10 =35-50=15 students which is how many plays soccer

Answer:

The p-value of the test is 0.0014 < 0.01, meaning that the data indicates that the true average unrestrained compressive strength is less than the design value of 3200.

Step-by-step explanation:

We want to determine whether the data indicate that the true average unrestrained compressive strength is less than the design value of 3200.

At the null hypothesis, we test if the mean is at the design value of 3200, so:

[tex]H_0: \mu = 3200[/tex]

At the alternate hypothesis, we test if it is less than the design value of 3200, so:

[tex]H_a: \mu < 3200[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

3200 is tested at the null hypothesis:

This means that [tex]\mu = 3200[/tex]

The sample average unrestrained compressive strength for 50 specimens of a particular type of brick was computed to be 3120 psi, and the sample standard deviation was 180.

This means that [tex]n = 50, X = 3120, s = 180[/tex]

Test statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{3120 - 3200}{\frac{180}{\sqrt{50}}}[/tex]

[tex]t = -3.14[/tex]

P-value of the test and decision:

The p-value of the test is the probability of finding a sample mean below 3120, which is the p-value of t = -3.14, using a one-tailed test, with 50 - 1 = 49 degrees of freedom.

With the help of a calculator, the p-value of the test is 0.0014

The p-value of the test is 0.0014 < 0.01, meaning that the data indicates that the true average unrestrained compressive strength is less than the design value of 3200.

Answer:

Its width is 9.66 feet and length is 22.98 feet.

Step-by-step explanation:

Let l is length and b is width of a rectangular lot.

Length, l = (3b-6) feet

The area of the lot is 222 sq feet.

The area of a rectangle is given by :

[tex]A=lb\\\\222=(3b-6)b\\\\222=3b^2-6b[/tex]

It is a quadratic equation. The solution of the above equation is given by :

b = 9.66 feet and -7.66 feet

Neglecting negative answer, the width of the lot is 9.66 feet.

Length, l = (3(9.66)-6) = 22.98 feet

Hence, its width is 9.66 feet and length is 22.98 feet.

Answer:

1.74

Step-by-step explanation:

Multiply 5.80 times .30

Answer:

1.74

Step-by-step explanation:

To solve this, lets multiply the value by the percentage.

Our value is 5.8

And our percentage is 30%.

Lets convert this into a decimal, to do this, divide 30 by 100:

30/100

=

0.3

Now that we have the percentage in decimal form, multiply it by the 5.8:

5.8*0.3

=

1.74

This is your answer!

Answer:

  no; √4 = 2

Step-by-step explanation:

If an integer is the square of another integer, its square root is rational. For example, 9 = 3², so √9 = 3, a rational number.

The square root of an integer is irrational if and only if the integer is not a perfect square.

Answer:

There were 80 pieces of colored paper in the package.

Step-by-step explanation:

Given that a package of colored paper contains 20 pieces of yellow paper, and this represents 25% of the total pieces of colored paper in the package, to determine how many total pieces of colored paper are in the package, the following calculation must be performed:

25 = 20

100 = X

100 x 20/25 = X

2,000 / 25 = X

80 = X

Therefore, there were 80 pieces of colored paper in the package.

X= -3 this solution is extraneous

X= 5 this solution is valid
