A = 1/2(4)(6.9)
A = 27.6 / 2
A = 13.8
answer
13.8 cm^2
Let's make W = width, and L = length.
What do we know? We know that P = 40 yards, and L = W + 1.5 .
The formulas for perimeter and area are:
P = 2W+2L
A = W*L
We can set P to 40, and since L = W+1.5, we can substitute that in for L.
40 = 2W + 2 (W+1.5)
40 = 2W + 2W + 3
37 = 4W
W = 37/4
We can plug that into L to find the length.
L = W + 1.5
L = 37/4 + 3/2
L = 43/4
Now, we plug into the area formula!
A = L*W
A = 43/4 * 37/4
A = 1591/16 or 99.43 yd^2
Answer: 2x+11x+1x+1=2x2+x+2xx
Step-by-step explanation:
Step 1: Factor both the numerator and the denominator. ...
Step 2: Write as one fraction. ...
Step 3: Simplify the rational expression. ...
Step 4: Multiply any remaining factors in the numerator and/or denominator. ...
Step 1: Factor both the numerator and the denominator.
Step 2: Write as one fraction.
Let
x-------> <span>the greater angle
y-------> </span><span>the smaller angle
we know that
x+y=90------> equation 1
y=x/5-------> equation 2
substitute equation 2 in equation 1
x+[x/5]=90-----> multiply by 5 both sides------> 5x+x=450
6x=450
x=75
y=x/5-----> y=75/5-----> y=15
the answer Part a) is
</span>the greater angle is 75°
the answer part b) is
the smaller angle is 15°
Answer:
You had to solve the equation to it's fullest (so work out the problem on paper) Apperently that is her version of explaining something and I lost 100 braincells reading that! XD
