Answer:
Step-by-step explanation:
Let x be gallons of 7%
Let y be gallons of 3%
364 = x + y
y = 364 - x
364(0.06) = x(0.07) + y(0.03)
364(6) = x(7) + y(3)
364(6) = 7x + 3y
364(6) = 7x + 3(364 - x)
364(6 - 3) = 7x - 3x
364(3) = 4x
x = 273
y = 364 - 273 = 91
273 gallons of 7%
91 gallons of 3%

True
Step-by-step explanation:
Answer:
4.5 cm
Step-by-step explanation:
KL = LM as triangle is isosceles
LM = KM as LF = FM = KN = NM, so the triangle is equilateral
EF ║ NM as LE⊥EF and LN⊥NM
EF is half the midsegment as ∠KLN ≅ ∠MLN, and LN is angle bisector of ∠KLM
Midsegment is half the side length, and all sides are 18 cm.
EF = 1/2(1/2*18) = 4.5 cm
Answer:
56.137 Square Unit
Step-by-step explanation:
Rectangle: 7x6=42
1/2 Circle: 1/2x3x3x
=14.137
42+14.137=56.137
Answer:
Angle L is a base angle and measures 72°.
Step-by-step explanation:
Triangle JKL is isosceles.
The measure of angle J is 72°
The measure of angle K is 36°
Angles in a trinagle add up to 180° so angle L is;
180° - (36° + 72°) = 72°
An isosceles triangle means that two of its sides are equal and two base angles are equal. So base angles are angles J and L and measures 72° each.
