Answer:
The expression (11.9f + 6.7g + 8.2h) cm represent the perimeter of the triangle
Step-by-step explanation:
Perimeter of a triangle = side a + side b + side c
Side a = (8.3f + 9.6g)
Side b = (3.6f + 1.5h)
Side c = (6.7h - 2.9g)
Perimeter of a triangle = side a + side b + side c
= (8.3f + 9.6g) + (3.6f + 1.5h) + (6.7h - 2.9g)
= 8.3f + 9.6g + 3.6f + 1.5h + 6.7h - 2.9g
Collect like terms
= 8.3f + 3.6f + 9.6g - 2.9g + 1.5h + 6.7h
= 11.9f + 6.7g + 8.2h
Perimeter of a triangle = (11.9f + 6.7g + 8.2h) cm
The expression (11.9f + 6.7g + 8.2h) cm represent the perimeter of the triangle
The arc length of the semicircle is 15.7
<h3>Calculating Arc length </h3>
From the question, we are to determine the arc length of the semicircle
Arc length can be determined by using the formula,
Arc length = θ/360° × 2πr
Where θ is the angle subtended by the arc
and r is the radius of the circle
In the given diagram,
θ = 180°
and r = 10/2
r = 5
Thus,
The arc length of the semicircle = 180°/360° ×2×3.14×5
The arc length of the semicircle = 1/2×2×3.14×5
The arc length of the semicircle = 15.7
Hence, the arc length of the semicircle is 15.7

Answer:
a) Triangle.
b) Triangle.
c) The area is 110 cm.
Step-by-step explanation:
The shape is given because it is a cross section of a Pyramid which we can see shaded in grey.
The area is given by the base times hight devided by 2. So 10cm * 22cm/2= 110cm.

She can make two triangle gardens with the six pieces of wood she has
Answer:
4 years and 2 months
Step-by-step explanation:
<u>Simple interest formula</u>
A = P(1 + rt)
where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- A = $500 × 2 = $1,000
- P = $500
- r = 24% = 0.24
Substitute the given values into the formula and solve for t:
Therefore, it takes 4 years and 2 months for the initial investment of $500 to double at a simple interested rate of 24%.
