$2-(\frac{7}{8} - \frac{3}{4}) = 2-(\frac{7}{8} -\frac{3\times2}{4\times2})=2 - (\frac{7}{8} - \frac{6}{8}) =\\\\2 - (\frac{7-6}{8}) = 2-\frac{1}{8} = \frac{16}{8} - \frac{1}{8} = \frac{15}{8} = \boxed{1\frac{7}{8}}$

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

The volume of a mini-basketball is approximately 4846.59 cubic centimeters. What is the approximate radius of a mini-basketball?

Sati [7]

Answer:

10.49823 centimeters

Step-by-step explanation:

Simply reverse the formula for the volume of a sphere: pi*r^3*(4/3).

So: pi*r^3*(4/3)=4846.59

r^3*(4/3)=1542.71751128

r^3*4=4628.15253384

r^3=1157.03813346

r=10.49823

(WILL AWARD BEST ANSWER) Is the relationship shown by the data linear? If so, model the data with an equation. (Data+Choices in

Mademuasel [1]

The relationship shown in this picture is linear. This can be determined by first looking at the x-column, and we can see that every value is continuously increasing by 4. Next, we look at the y-column, and we can see that each y-value is steadily increasing by 5. Since it is not increasing by a <u>factor</u> of 5, it is not exponential, it is linear. After we have determined this, we need to find the slope of the coordinates. To do this, we must take two coordinates - (1, 5) and (5, 10). Then, we need to plug in the respective values into the slope formula, giving us a slope of 5/4. Now, we take the first coordinate point in the table, (1, 5). Now, just put all the derived information into point-slope form, which gives us y - 5 = 5/4(x - 1). Therefore, the answer to your problem is B) The relationship is linear; y - 5 = 5/4(x - 1). Hope this helped!
