Ebony walked at a rate of 3 1/2 miles per hour for 1 1/3 hours. how far did she walk?

Answers

Answer 1

Answer:

Answer:

She walked $4(2)/(3)$ miles

Step-by-step explanation:

Speed of ebony = $3(1)/(2)$ miles/hour

= $(7)/(2)$ miles/hour

Time Taken = $1(1)/(3)$ hours.

= $(4)/(3)$ hours.

We are supposed to find how far did she walk i.e. Distance

Formula : $Distance = Speed * Time$

$Distance = (7)/(2) * (4)/(3)$

$Distance = (14)/(3)$

$Distance = 4(2)/(3)$

Hence she walked $4(2)/(3)$ miles

A bicycle wheel makes five rotations. The bicycle travels 41.87 ft. Find the diameter of the wheel in inches. Use 3.14 for pi. The diameter of the wheel is about nothing in.

Answers

Answer:

The diameter is 32.04 Inches

Step-by-step explanation:

If the Bicycle makes 5 rotations and it equals 41.87 ft

Then 1 rotation around the circumference is

41.87/5 = 8.374 ft

Circumference = $\pi d$

8.374 = 3.14*d

Divide both sides by 3.14

d = 8.374/3.14

d = 2.67 ft

To convert feet to inches, we multiply by 12

d = 2.67*12 inches

d = 32.04 Inches

How do you graph and work problem x+4y=16??

Answers

You have to give values to x or y to create points which can be represented on a system of axis. For example, for x=0 we would get 4y=16, so y=4 => A(0, 4). For y = 0 we would get x=16, so B(16, 0). I attached the graph

Answer: x = 4

If 10 men can complete a piece of work in 30 days how many men are requiredto complete the same job in 25 days?

Answers

We must assume that all workmen work at the same rate, and keep it up forever.

More men ==> fewer days

so the proportion is: 30/25 = x/10

Cross-multiply the proportion:

300 = 25 x

Divide each side by 25 :

x = 300/25 = 12 men

Your family went out to dinner at Applebee's and left the waiter an 18% tip. If the total before the tip for the dinner was $47.98 what should be paid to the waitress as a tip

Step-by-step explanation:

0.18 x $47.98=$8.64

To calculate the volume of a cylinder, we have equation like this: V = πd 2 4 h = πr 2h d is the diameter, r is the radius and h is its height. We can measure the diameter (r = d 2 ) and height directly. To calculate the confidence interval of the volume, we should use the propagation of errors. We use the micrometer screw to measure the diameter. The minimum interval on the screw is 0.01mm. What is the confidence interval for δd and δr?

Answers

Answer:

$\delta d =$ +/- 0.01 mm

$\delta r =$ +/- 0.02 mm

Step-by-step explanation:

$\delta d$ . The error of a quantity directly measured is the uncertainty of the tool used for measuring. So error for diameter is 0.01 mm.

$\delta r$ . The error of a quantity obtained multiplying/dividing a measure by a constant is calculated multiplying/dividing the measure uncertainity by the same constant. Radius is calculated as r=2*d, so we calculate $\delta r$ multiplying the diameter uncertainty by 2 ( $\delta r = 2*0.01=0.02$ ).
