Answer:
a) 22°
Step-by-step explanation:
Side 'a' is the shortest side, so angle A will be the smallest angle. Its value must be less than 60°, eliminating the last two answer choices. The actual value can be found from the Law of Cosines.
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (5² +7² -3²)/(2(5)(7)) = 65/70
A = arccos(65/70) ≈ 21.7868°
Angle A is about 22°.
Answer:
Option c.
Step-by-step explanation:
Using the normal curve to approximate a sampling distribution:
For a sample size n and a proportion n, the normal curve can be used if:
and
Option a:
So option a cannot be used.
Option b:
So option b cannot be used.
Option c:
So option c can be used, and is the answer
Option d:
So option d cannot be used.
The answer is given by option c.
The perimeter of a rectangle is 34 units. Its width W is 6.5 units.
Write an equation to represent the perimeter in terms of the length L, and find the value of L
<h3><u>Answer:</u></h3>The length of rectangle is 10.5 units
<h3><u>Solution:</u></h3>Given that,
Perimeter of rectangle = 34 units
Width of rectangle = 6.5 units
Let "L" be the length of rectangle
<em><u>The perimeter of rectangle is given by formula:</u></em>
Perimeter = 2(length + width)
<em><u>Substituting the values we get,</u></em>
Thus the equation is found
<em><u>Solve for "L"</u></em>
Thus length of rectangle is 10.5 units
Answer:
7 pounds of almond
Step-by-step explanation:
It is $3.50 per pound.
If she spent a total of $24.50, just divide 24.50 by 3.50
= 7
We can verify this by multiplying 3.50 by 7 which gives us 24.50
