What's the difference -1, 098 3/20 and -2, 784.72​

Mathematics
1 answer:
Mashutka [201]2 years ago
4 0

Step-by-step explanation:

you know what 3/20 is in decimal form ?

it is literally dividing 3 by 20. and the result is 0.15.

you can get this skating by converting the fraction to n/100.

it means to multiply numerator and denominator by 5

3/20 × 5/5 = 15/100 = 0.15

so, the first number is actually

-1,098.15

now the difference is not so difficult anymore, right ?

-1,098.15 - -2,784.72 = -1,098.15 + 2,784.72 = 1,686.57

Find the volume of a cylinder with diameter 8 inches and height 9 1/2 inches
marta [7]

Answer:

V=152\pi in^{2} in terms or pi

V=477.52in^{2} simplified

Step-by-step explanation:

To solve this, we are using the Cylinder's volume formula:

V=\pi r^{2} h

where

V is the volume of the cylinder

r is the radius of the cylinder

Remember that radius is half the diameter, so we can divide the diameter of our cylinder by 2 to find its radius: r=\frac{d}{2} =\frac{8in}{2} =4in. Now, 9 1/2 inches is 9 and a half inches, so h=9.5in.

Replacing values:

V=\pi (4in)^{2} (9.5in)

V=\pi (16in^{2})(9.5in)

V=152\pi in^{2}

V=477.52in^{2}

We can conclude that the volume of our cylinder is V=152\pi in^{2} in terms of pi, or V=477.52in^{2} simplified.

Let Angle w be an acute angle. Use a calculator to approximate the me
serious [3.7K]

Answer:

<h2>49.5°</h2>

Step-by-step explanation:

Given the trigonometry function as shown sin W = 0.79, to get W, the following steps must be followed.

Step 1: Take the arcsin of both sides of the equation

sin^{-1}(sinW) =  sin^{-1}0.79\\W = sin^{-1}0.79

Step 2: Use a calculator to get the resulting value of W

W = 49.46^{0}

W = 49.5^{0} (to nearest tenth of a degree)

This gives the acute angle needed.

Note that acute angle are angles that are less than 90°

Two cargo ships are sailing a direct course into harbor. Ship A is 22 miles from harbor. Ship Bis sailing into harbor on a cours
s344n2d4d5 [400]

Answer:

The distance of ship B from the Harbor is 32.26 miles

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.

I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the <u>COSINE operator</u> to solve for the length of the course of ship B.

cos(x) = \frac{adjacent}{hypotenuse}

cos(47) = \frac{22miles}{hypotenuse} .... flip both fractions.

\frac{1}{cos(47)} = \frac{hypotenuse}{22miles} .... multiply both sides by 22

\frac{22mi}{cos(47)} = hypotenuse

32.26mi = hypotenuse = B

So the distance of ship B from the Harbor is 32.26 miles

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
