Answer:
45 square units.
Step-by-step explanation:
Applying the pythagoras theorem:
Base of the bigger triangle =
=
= 12 units
Area of a triangle is given by
× base × height
The area of the bigger triangle is
× 12 × 9 = 54 square units.
The area of the smallest triangle is
× (12 - 10) × 9 = 9 square units.
The area of the figure( required triangle) is 54 - 9 = 45 square units.
Answer:
n=−5
Step-by-step explanation:
n−4−3n=3n+6−3n
−2n−4=6
Step 2: Add 4 to both sides.
−2n−4+4=6+4
−2n=10
Step 3: Divide both sides by -2.
−2n
/−2
= 10
/−2
n=−5
The answer is 8.031 per person
∗ l = 50.6 ft
∗ w = ?
∗ The length is 50.6 feet. The question is saying that 50.6 is 5.8 feet less than 6 times the width.
∗ 6w - 5.8 = 50.6
∗ 6w = 56.4
∗ w = 9.4
Now lets check.
∗ If the length is 5.8 feet less than 6 times the width, and we found 9.4 as the answer, then;
6 times 9.4 - 5.8 should equal 50.6
∗ 6 • 9.4 - 5.8 = l
∗ 56.4 - 5.8 = l
∗ 50.6 = l
⋆The width is 9.4 feet⋆
