Step-by-step explanation:
1 m = 3.280839895... ft
therefore,
1 m² = 10.76391042... ft²
35 m² = 35 × 10.76391042... ft² =
= 376.7368646... ft²
the area of the circle is
pi×r²
r = 50/2 = 25 ft
so, the area of the red circle is
pi×25² = pi×625 = 1,963.495408... ft²
we need to paint it twice, so the area to be painted is twice the area of the circle
2×pi×625 = 3,926.990817... ft²
we need a many cans as the cover area of a single can fits into the total area to be painted :
3,926.990817... / 376.7368646... = 10.42369671... cans
we need to round this up to full cans.
so, we need 11 cans of red paint to give that red pad 2 coats of paint.
Triangle QPR is equal to triangle ABC
An equilateral triangle has 3 equal sides. Since one side is 14 cm, then all sides are 14 cm. You multiply 4 by 3 and you get your answer.
14*3=42. The perimeter is 42cm.
Answer:
No Solution
Step-by-step explanation:
Assuming the lines are absolute value you must get rid of the other numbers first so:
5 |x+7| + 14 = 8
5 |x+7| = -6
and since absolute values can't equal a negative the answer is NO SOLUTION
The correlation coefficient represents a moderate negative correlation is -0.64.
<h2>We have to determine</h2>
Which correlation coefficient represents a moderate negative correlation?
<h3>According to the question</h3>
The correlation coefficient is a measure of the strength of the linear relationship between two variables and is denoted by r.
The values between 0.3 and 0.7 indicate a moderate positive (negative) linear relationship.
The values between -0.3 and -0.7 indicate a moderate negative linear relationship.
The only value of r in the option is r= -0.64 lies in a given interval of the moderate negative linear relationship.
Hence, the correlation coefficient represents a moderate negative correlation is -0.64.
