Answer:

Area of triangle = 8.9

Area of parallelogram = 53.4 yd² (option A)

Step-by-step explanation:

✔️Area of the triangle = ½*base*height

base = 3 m

height = 5.9 m

Area of triangle = ½*3*5.9

Area of triangle = 8.85 ≈ 8.9 (nearest tenth)

✔️Area of parallelogram = base*height

base = 8.9 yd

height = 6 yd

Area of parallelogram = 8.9*6 = 53.4 yd²

<h3 /><h3>Midpoint of coordinate points</h3>

The formula for calculating the midpoint of coordinate is expressed as:

M(x, y) = {(x₁+x₂)/2, (y₁+y₂)/2}

Given the coordinate between their locations at (-4, 4) and (-9, 8)

Determine the midpoint

x = (-4+9)/2

x =5/2 = 2.5

Similarly

y = 4-8/2

y = -4/2

y = -2

Hence the point that Sam's house is located is at (2.5, -2)

3. You purchase a car using a $20,000 loan with a 5% simple interest rate.

finlep [7]

(a) 20,000 × 5/100 × 4 = $4000( interest)

(b) 20000 × 5/100 × 2 = $2000 (interest)

How much do you save = $4000 - $2000 = $2000

what are a) the ratio of the perimeters and b) the ratio of the areas of the larger figure to the smaller figure? the figures ar

Alla [95]

We know that

a) find <span>the ratio of the perimeters
</span><span>
the ratio of the perimeters is equal to the scale factor
</span>scale factor=26/6-----> 13/3
the answer Part a) is
the ratio of the perimeters is 13/3

b) find <span>the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]</span>²*area smaller figure
scale factor²=area larger figure/area smaller figure

the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²----> 169/9

the answer Part b) is
169/9

the complete answer is
13/3 and 169/9

Given the following coordinates complete the reflection transformation. A(1,−5) B(2,−2) C(5,−2) Transformation: Complete the dou

Dmitriy789 [7]

Answer:

A''(1,-1) B''(2,2) C''(5,2)

Step-by-step explanation:

Points A(1,−5) B(2,−2) C(5,−2)

reflection over y=-1

Perpendicular distance between points y-coordinates of points (A, B and C) and y=-1 are 4,1 and 1

after reflections, the perpendicular distance will be 8,2,2 and the points will be at

A'(1,3) B'(2,0) C'(5,0)

again reflection over y=1

Perpendicular distance between points y-coordinates of points (A', B' and C') and y=1 are 2,1 and 1

after reflections, the perpendicular distance will be 4,2,2 and the points will be at

A''(1,-1) B''(2,2) C''(5,2)!
