The perimeter of triangle XYZ will be:

40r + 30r + 60r = 130r

The area of triangle ABC is n² so the area of triangle XYZ will be n²×r²

Answer:

Part A. Option B.

Part B. Option C.

Step-by-step explanation:

The sides of ΔABC are 30 units, 40 units and 60 units long.

The corresponding sides of ΔXYZ are r times as long as the sides of ΔABC.

Therefore sides of ΔXYZ will be 30r units, 40r units and 60r units.

Perimeter of ΔXYZ = 30r + 40r + 60r = 130r

Option B. is the answer.

If the area of ΔABC is n square units then we have to find the area of ΔXYZ.

Since all sides of ΔXYZ are r times of ΔABC, so area of ΔABC = \frac{1}{2}(Base)(height)

Area of ΔXYZ = \frac{1}{2}(r.height)(r.base)=n(r.r)

= n(r)²

Option C is the answer.

What is the multiplication inverse or reciprocal of each number?
Degger [83]

Answer:

4

9/8

Step-by-step explanation:

Given the fraction a/b, the reciprocal is expressed as 1/(a/b) = b/a

For 1/4;

1/4

= 1÷1/4

= 1 * 4/1

= 4

Hence the reciprocal is 4

b) 8/9

= 1 ÷ 8/9

= 1 * 9/8

= 9/8

Hence the reciprocal of 8/9 is 9/8

4) How much pizza sauce is needed to cover a 16" pizza? (Note: 16" is the diameter of the pizza.) A) 50.24 in2 B) 200.96 in2 C)
never [62]
In order to get how much is being covered, we need to know the formula of the area of a circle.
Area = pi * r^2
Area = pi * (16/2)^2
Area = pi * 8^2
Area = pi * 64
Area = 200.96 in^2

So the correct answer is letter B. 200.96 in^2

1.What is the area of this parallelogram?
dexar [7]

Question 1: Option D

Area of the parallelogram = 132 cm²

Question 2: Option B

Area of the parallelogram = 3.60 ft²

Solution:

Question 1:

Base of the parallelogram = 6 + 5 = 11 cm

Height of the parallelogram = 12 cm

Area of the parallelogram = Base × Height

                                           = 11 × 12

Area of the parallelogram = 132 cm²

Option D is the correct answer.

Question 2:

Base of the parallelogram = 1.9 + 0.5 = 2.4 ft

Height of the parallelogram = 1.5 ft

Area of the parallelogram = Base × Height

                                           = 2.4 × 1.5

Area of the parallelogram = 3.60 ft²

Option B is the correct answer.
