3/4 + (-1/2) + (-2/3) explain me

Answers

Answer 1

Answer:

Remove the parentheses, use LCM (least common multiplier), adjust fractions based on the LCM, since denominators are equal, combine the fractions, subtract. Your answer would be: -5/12.

Step-by-step explanation:

Steps to the words I said but in fraction step:

3/4 + (-1/2) + (-2/3)

3/4 - 1/2 - 2/3

9/12 - 6/12 - 8/12

9-6-8/12

-5/12

The path of a projectile launched from a 26-ft-tall tower is modeled by the equation y = −16t2 + 64t + 26. What is the maximum height, in feet, reached by the projectile?

Answers

Answer:

The maximum height of the projectile is 90 ft

Step-by-step explanation:

Here, we want to get the maximum height reached by the projectile

The answer here will be the y-coordinate value of the vertex form of the given equation

so firstly, we have to write the equation in the vertex form

We have this as;

y = -16t^2 + 64t + 26

That will be;

y = a(x-h)^2 + k

y = -16(x-2)^2 + 90

where the vertex of the equation is;

(-h,k)

K

in this case is 90 and thus, that is the maximum height of the projectile

hi whats th median price of the items for 9.00 8.00 8.00 7.00 6.00​

Answers

Answer:

8.00

Step-by-step explanation:

to find the median, you have to order all your numbers from least to greatest (6.00, 7.00, 8.00, 8.00, 9.00) then find the number in the MIDDLE. that number would be 8.00 so therefore the median is 8.00.

If steak costs $12.55 per pound, what will be the total cost of 0.6 pounds of steak?\

Answers

Answer:

Solve for X; whereas lb=pound, $=cost

1lb = $12.55

0.6lb = $X; therefore 6/10 lb = $X

Rewrite:

$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10

A stepladder has an angle of elevation of 60° with the front of the house. The length of the stepladder is 24 feet. At what height does the stepladder meet the house?

Answers

Answer:

20.78 feets

Step-by-step explanation:

Based on the solution diagram attached below :

The height at which the step ladder meets the house can be obtained thus :

Using trigonometry :

Sin θ = opposite / hypotenus

Sin θ = h / 24

Sin 60 = h / 24

0.8660254 = h/24

Height, h = 0.8660254 * 24

Height, h = 20.78 feets

Part b:  Find the length of the sidewalk.  The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3.  Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:

                                     

cos 30° = adj / hyp, or:

                           

  √3       2√3

 ------- = --------

     2        hyp

This simplifies to

     1          2

 -------- = -------

      2        hyp

Cross multiplying results in:  hyp = 4.  The sidewalk length is 4 miles.

a.  The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:

                               1       opposite side

sin 30 degrees = ----- = -------------------------   or 2(opp side) = 4.

                               2                 4

Then the opp side, which is the width of the park, is 2.

The total surface area of a cylinder with height 5 in. is given by the function g(x) = 2πx2 + 10πx, where x is the radius, and the function f(x) = 10πx gives the surface area of the side of the cylinder. Which combined function gives the total surface area of the two bases of the cylinder? A. f + g B. f – g C. g – f D. f · g

Answers

Answer:

C. g - f

Step-by-step explanation:

Total surface area of a cylinder with height 5 is:

A = 2πrh + 2πr² = 10πr + 2πr²

If we substitute r with x, we get:

g(x) - full surface areaf(x) - surface area

Total surface area of two bases:

g - f = 2πx² + 10πx - 10πx = 2πx²
