Answer:

D.) 38 cm²

Step-by-step explanation:

apologies if this isn't correct but I hope it is, anyway have a good day/night!

the area of the figure is 38.28cm².

The area of the shape is the sum of the area of the semicircle, a rectangle, and a right triangle.

Area of a semicircle = [tex]\frac{1}{2}[/tex]πr²

[tex]\frac{1}{2}[/tex]x 3.14 x (4/2)²  = 6.28 cm²

Area of the rectangle = length x width

6 x 4 = 24 cm²

Area of the right triangle =  [tex]\frac{1}{2}[/tex]x base x height

[tex]\frac{1}{2}[/tex]x (10 - 6) x 4 = 8cm²

Sum of the areas = 8 + 24 + 6.28 = 38.28cm²

1. 4/3, and 1 & 1/3   2. 1 & 2/3    3. I D K.    4. 3

5. 1

Step-by-step explanation:

1. because 4/3 is the same as 1 & 1/3, they are the same because if you take the 4 and make it a 3, it is 1 whole, and then you put 1/3 at the end, because the is still a left over 1/3.    2. I know this because 2/3 is bigger than 1/3, and 4/3 is equal to 1 & 1/3.

3. Two planes are 1620 miles apart and are traveling toward each other. One plane is traveling 120 mph faster than the other plane. The planes meet in 1.5 hours. Find the speed of each plane. PLEASE SHOW WORK I WILL MAKE BRAINLIST PLEASE !!!!!!!!!

Answers

Answer:

480 mph and 600 mph

Step-by-step explanation:

we can call the first planes speed x, and the other x+120 because it is going 120 mph faster. Because distance = rate * time, that means that 1620 = 1.5*(x+x+120) and then you just solve the equation

1620=1.5*(x+x+120)

1620=1.5*(2x+120)

1620=3x+180

1440=3x

x=480

x+120=600

Significant resources are allocated to mitigate the risk. Our company is committed to ensuring that employees, visitors and contractors are kept as safe as possible whilst at any premises owned or under the control of the organisation. With this in mind, all staff should familiarise themselves with the locations of the fire alarms, fire call points, fire exits, fire assembly areas and fire tally boards. On discovering a fire, you should operate the nearest alarm, evacuate the building as described below and report the nature and location of the fire to the companys fire warden. On hearing the fire alarm, you should:Quickly and calmly evacuate to the nearest assembly area.Where there is anyone with mobility impairments, utilise the evacuation chair (if trained in its use) or escort them to a temporary refuge point i.e. stairwell or corridors protected by 30 minute fire doors and remain with them if appropriate.Members of staff: If you are near the tally board AND the visitor sign-in sheet, you must pick up both, check the rooms shown on the tally board as you exit and close all doors behind you. Note the location of anyone with mobility impairment who has been escorted to a temporary refuge point. If the tally board/visitor sign-in sheet has already been collected, go straight to the assembly area.If you have collected the tally board and visitor sign-in sheet and checked the rooms as you left the building, you must report with the tally board and visitor sign-in sheet to the companys Fire Warden without delay, informing him/her of the location of any one with mobility impairments waiting in a safe area.If you have looked for a tally board that you know is missing from its usual location, then report this to the companys Fire Warden.Fire wardens should assume their designated duties.

DO NOT attempt to fight a fire unless you have been trained to and it is safe to do so.DO NOT leave the site unless instructed to do so.Why do you think the visitor sign-in sheet needs to be taken?- it is part of the fire evacuation procedure.- the visitor sign in sheet helps account for evacuated visitors accurately.- the visitors sign in sheet can help to locate people.- it assists the fire warden to evacuate people more quickly Europeans and Africans obtainedfrom the New World.A. new products, new cultures, and new ideasB. new slaves and new immigrantsC. new exchanges??
