Answer:

D. 6 7/8

Step-by-step explanation:

First, convert 2 3/4 to an improper fraction.

2 times 4 = 8

8+3=11

11/4 ÷2/5

Then, flip the second fraction and change the sign to multiplication.

11/4 × 5/2

Multiply.

11 × 5 = 55

4 × 2 = 6

55/6

Simplify the fraction.

6 7/8

The data set represents the number of minutes Dan spent on his homework each night.

ra1l [238]

Answer:

The answer is A. (or the first one)

Step-by-step explanation:

It's not D because the median is 46. It is not B or C either because the IQR is 35 and the OQR is 53.5 and A is the only one that has that. Hope it helped :)

What is the simple interest value missing in the table? Principal $2,500 Interest rate 3.5% Time 5 years Interest ? $43.75 $437.

netineya [11]

Answer:

$4,3750.00

Step-by-step explanation:

Simple interest is calculated using the equation:

I = Prt

I = Interest

P = Principal

r = Rate

t = Time (years)

I = 2,500 * 3.5 * 5

43750 = 2,500 * 3.5 * 5

Therefore, the interest is $43750.00

A 10 ft pole has a support rope that extends from the top of the pole to the ground. The rope and the ground form a 30 degree an

mr Goodwill [35]

Answer:

The length of rope is 20.0 ft . Hence, <u>option (1) </u> is correct.

Step-by-step explanation:

In the figure below AB represents pole having height 10 ft and AC represents the rope that is from the top of pole to the ground. BC represent the ground distance from base of tower to the rope.

The rope and the ground form a 30 degree angle that is the angle between BC and AC is 30°.

In right angled triangle ABC with right angle at B.

Since we have to find the length of rope that is the value of side AC.

Using trigonometric ratios

$\sin C=\frac{\text{perpendicular}}{\text{hypotenuse}}$
