Answer:

Only one triangle.

Step-by-step explanation:

Given that in a triangle one side measures 4 feet.

Two angles of the triangle are 50 and 80 degrees

Since sum of angles is 180 degrees, we have the third angle = 50 degrees.

When three angles are fixed as 50,80 and 50 and one side =4, there can be only one triangle.

So answer is only one triangle can be constructed.

Since we have the triangle, but don't know which side 4 is on, we have one where x is opposite a 50 degree angle (they are the same if across either 50 degree side) and another across the 80 degree one. In addition, it's really ratios and sin/cos/tan from there!

Which of these numbers is between 5/6 and 1?<br> (A) 4/5 <br> (B) 4/7 <br> (C)6/7
djverab [1.8K]
Two basic ways in which to do this problem:

1.  Find and apply the LCD.

2.  Convert all of the given numbers to their decimal form, to 2 or 3 places only.

Try #2 first:

5/6 = 0.83    

4/5 = 0.80 is not between 5/6 and 1.  Reject it.
4/7 = 0.57 Reject
6/7 = 0.86 This is between 5/6 and1.  This is the answer.

The sum of two numbers is 21. The larger number is 6 less than twice the smaller number. Find the two numbers.
never [62]
The sum of two numbers
 x + y = 21
x = smaller number
y = larger number

Larger Number = y = (2x -6)
Substitute  (2x - 6) for y
x + y = 21
x + (2x - 6) = 21
3x - 6 = 21
3x = 21 + 6
3x = 27
3x / 3 = 27 / 3
x =  9
Smaller number = x = 9
Find the larger number by inserting 9 into (2x - 6)
(2x - 6)
(2(9) - 6)
18 - 6
12

So 
x = 9
y =12

Check our answer by inserting x = 9 and y = 12 into  x + y = 21
x + y =21
9 + 12 = 21
21 = 21 
So since we have 21 = 21 we know our answer is correct.

Which statement is true about the end behavior of the graphed function?
dlinn [17]

Answer:

"As the x-values go to positive infinity, the function's values go to positive infinity."

Step-by-step explanation:

End-Behavior of a fucntion is basically what happens to the function when x goes to positive infinity and when x goes to negative infinity.

In this function, we can say:

  • as we move to the right (x increases), the value of the function (y-value) increases towards positive infinity.
  • Also,
  • as we move to the left (x decreases), the value of the function (y-value) decreases towards negative infinity.

From the answer choices, we take the last one -- "As the x-values go to positive infinity, the function's values go to positive infinity."

* Note, this is a cubic function

Chris used 43.96 feet of fencing to enclose a circular garden. What is the radius, in feet, of the garden?
UNO [17]

Answer:

r = 7 ft

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here C = 43.96 , then

2πr = 43.96 ( divide both sides by 2 × 3.14 ← for π )

r = \frac{43.96}{2(3.14)} = \frac{43.96}{6.28} = 7 ft
