For the first question, the answer is A. You take 90 and multiply it by 3, then you get the time that it takes for one worker to mow the large park. 

For the second question, you take 50 = k/0.25. To find k, you would want to multiply both sides with 0.25 to cancel the 0.25 on k's side. 50 times 0.25 is 12.5. I think C is your answer although I'm not really confident.

A right triangle (triangle 1) has a hypotenuse length of 115 mm and α = 31.2°. What are the measurements for a, b, and β? 2. A r
kirza4 [7]

Alright, lets get started.

A right triangle (triangle 1) has a hypotenuse length of 115 mm and α = 31.2°. What are the measurements for a, b, and β?

Please refer the diagram I have attached.

Using SOH CAH TOA,

sin 31.2 = \frac{b}{115}

b = 115 sin31.2

Plugging the value of sin 31.2

b = 115*0.518 = 59.57 mm

Similarly,

cos31.2 = \frac{a}{115}

a = 115cos31.2

Plugging the value of cos 31.2

a = 115*.8553 = 98.36 mm

Now, for angle β

tan β = \frac{98.36}{59.57}

tan β = 1.65

Using tan inverse

β = 58.78°

So, the answer is a = 98.36 mm, b = 59.57 mm and β = 58.78°   :   Answer

Hope it will help :)

A right triangle (triangle 1) has measurements of a = 505 mm and b = 286 mm. What are the measurements for c, α, and β?

Please refer the diagram I have attahced.

a and b are given, we could side c by using Pythagorean theorem.

c^2 = a^2 +b^2

c^2 = 505^2 + 286^2

c^2 = 255025+81796

c^2 = 336821

Taking square root on both sides

c = 580.36 mm

Using SOH CAH TOA,

tan α = \frac{505}{286}

taking tan inverse

α = 60.48°

Similarly,

tan β = \frac{286}{505}

taking tan inverse

β = 29.52°

So, the answer is c = 580.36 mm, α = 60.48° and β = 29.52°   :    Answer

Hope it will help :)

A cable on a crane measures 89 yards 2 feet. How much total cable would be on 14 identical cranes? Convert the answer to larger
babymother [125]

we know that  

1 yard=3 feet

Multiply (89 yards 2 feet) by 14

(89 yards 2 feet)*14=89*14 yards 2*14 feet-------> 1,246 yards 28 feet

convert 28 feet to yards

28 ft=(28/3) yards=9.33 yards

9.33 yards=9 yards+0.33 yards

0.33 yards=1 foot

so

9.33 yards=9 yards+1 foot

substitute

1,246 yards 28 feet=1,246 yards +9 yards+1 foot----->1,255  yards + 1 foot

therefore

<u>the answer is the option</u>

C. 1,255 yards 1 foot
