Which equation is true for the triangle?

Mathematics
1 answer:
Kamila [148]2 years ago
5 0

Answer:

D

Step-by-step explanation:

the three main trig functions are

sin = opposite / hypotenuse

cos = adjacent / hypotenuse

tan = opposite / adjacent

( opposite = side opposite of angle , hypotenuse = longest side and adjacent = other side )

Sin(55) = a/c as side a is opposite of the angle and c is the hypotenuse so D might be the answer

cos(55) would be b/c as the adjacent of that angle is b and the hypotenuse is c. B and C show the wrong ratios so B and C can't be the answer

tan(55) would be a/b as side a is opposite of the angle and b is the adjacent, A says c/a which is wrong

so we can conclude the answer is D

Find the root<br><br> X^3-125=0
Firlakuza [10]

Steps to solve:

x^3 - 125 = 0

~Add 125 to both sides

x^3 = 125

~Take cube root of both sides

x = 5

Best of Luck!

Answer:

0.150 < (Proportion of Sandy's pie) < 0.167

15% < (Percentage of Sandy's pie) < 16.7%

Step-by-step explanation:

Total percentage of pie = 100% or 1

George, Sandy, Carlos, and Michelle all ate a piece of the pie.

George ate a fraction of 0.150

Michelle ate a fraction of (1/6) = 0.167

Carlos ate a fraction of (1/7) = 0.143

The amount of pie left = 1 - 0.15 - (1/6) - (1/7) = 0.5405

And Sandy is known to eat more than two of her friends, but less than one of them.

Of the amount of pie eaten by the first 3 friends, (1/6) is the highest proportion.

Hence, it is evident that Sandy ate more than 0.143 and 0.150 (Carlos and George) but less than Michelle (0.167).

So, mathematically, the possible proportion of cake that Sandy ate is

0.150 < (Proportion of Sandy's pie) < 0.167

Hope this Helps!!!

When truckers are on long-haul drives, their driving logs must reflect their average speed. Average speed is the total distance
KengaRu [80]

Answer:

0.500 hour

Step-by-step explanation:

Givens

<em><u>Distance</u></em>

  • Total Distance on the highway = 3hr * 60 miles / hr = 180 miles
  • Distance in the city = 20 miles
  • Total Distance = 180 + 20 = 200 miles

<em><u>Time</u></em>

  • Time on the highway = 3 hours
  • Time in the city = x

Formula

d /t = r

Solution

  • Average rate = 57.14
  • Total Distance / Total Time = average rate
  • 200 / (3 + x) = 57.14                               Multiply both sides by 3 + x
  • 200 = 57.14 * (3 + x)                               Remove the brackets
  • 200 = 57.14*3 + 57.14x                           Multiply the factors on the right
  • 200 = 171.42 + 57.14x                              Subtract 171.42 from both sides.
  • 200 - 171.42 = 171.42 - 171.42 + 57.14x   So the subtraction
  • 28.58 = 57.14x                                         Divide by 57.14
  • 28.57/57.14 = x
  • x = 0.500 hour                                        Answer
