To change knots per hour, use the expression 1.15k, where k is the speed in in knots per hour. A plane is flying at 300 knots pe

Free_Kalibri [48]

1.15(300).
Substitute k for 300, since the plane is flying 300 knots per hour, and k=knots per hour.

1.15(300)=345 miles per hour
After multiplying, 300 by 1.15, you get 345 miles per hour. This is the speed of the plane from Knots to MPH (Miles Per Hour).

In the triangle below,<br> y = [ ? ] cm. Round to the<br> nearest tenth.

sattari [20]

Answer:

The answer is

Step-by-step explanation:

Since the triangle is a right angled triangle we can use trigonometric ratios to find y

To find y we use cosine

cos∅ = adjacent / hypotenuse

From the question

y is the adjacent

The hypotenuse is 15

So we have

$\cos(35) = \frac{y}{15} \\ y = 15 \cos( 35 ) \\ y = 12.28728$

We have the final answer as

<h3>12.3 cm to the nearest tenth</h3>

The dictionary is 3 inches thick. What is the volume of the dictionary

Yuki888 [10]

Answer:

Square shaped = 27 cubic inches , Rectangular shaped = 3LW cubic Inches

Step-by-step explanation:

If the dictionary is a square ( all sides are equal ) the the volume is

V = Length * Length * Length = $L^{3}$

V = 3 * 3 * 3 = 27 $inch^{3}$

while if its rectangular ( all side are not equal ) shaped

V = Length * Width * Height (thickness)

V = L * W * 3 = 3LW $inch^{3}$

The radius of a wheel is 21m.how much distance will it covers when it rotates 5 times?

mrs_skeptik [129]

Answer:

Distance = 660 meters

Step-by-step explanation:

Given the following data;

Radius, r = 21 m

Number of revolutions = 5 times

To find the distance covered;

The distance covered in one revolution is given by the circumference of a circle.

Mathematically, circumfeence of a circle is equal to;

C = 2πr

Substituting into the formula, we have;

C = 2 * 22/7 * 21

C = 44 * 3

C = 132 meters

Next, we find the distance covered;

Distance = Circumference * Number of revolutions

Distance = 132 * 5

Distance = 660 meters
