Mathematics

Answer:

Step-by-step explanation:

2l+2w= 50

l= 4w-8

2 (4W - 8) + 2W = 50.

2 (4W - 8) + 2W = 50

8W - 16 + 2W = 50

10W - 16 = 50

10W = 66

W = 6.6 meters

Solve for L

L = 4W - 8

L = 4 (6.6) -8

L = 26.4 - 8

L = 18.4

Dimensions are 6.6 and 18.4

I hope this is right

Answer/Step-by-step explanation:

1. The figure is composed of a triangle and a rectangle.

Area of the triangle = ½*base*height

base = 4 ft

height = 12 - 8 = 4ft

Area of triangle = ½*4*4 = 8 ft²

Area of rectangle = length * width

Length = 8 ft

Width = 4 ft

Area of rectangle = 8*4 = 32 ft²

✔️Area of the figure = 8 + 32 = 40 ft²

2. The figure is composed of a semicircle and a triangle

Area of the semicircle = ½(πr²)

radius (r) = 3 cm

π = 3

Area = ½(3*3²) = 13.5 cm²

Area of triangle = ½*base*height

base = 3*2 = 6 cm

height = 6 cm

Area = ½*6*6 = 6 cm²

✔️Area of the figure = 13.5 + 6 = 19.5 cm²

Bill wants to rent a car.Rental Company A charges $35 per day plus $0.10 per mile driven.Rental Company B charges $25 per day pl
zlopas [31]

Answer:

m = 200 miles

Step-by-step explanation:

Rental Co. A:  A(m) = $35 + ($0.10/mile)(m), where m is the number of miles driven

Rental Co. B:  B(m) = $25 + ($0.15/mile)(m)

Set these two dollar amounts equal to each other and solve for m:

$25 + ($0.15/mile)m = $35 + ($0.10/mile)(m).  Combine like terms, obtaining:

($0.05/mile)m = $10; then m = ($10) / ($0.05/mile), or 200 miles.

The price charged by the two companies would be the same when the car has been driven 200 miles.

Read the numbers and decide what the next number should be. 5 15 6 18 7 21 8
VikaD [51]

we have

5,15 \\6, 18 \\7,21 \\8,?

Let

a1=5\\b1=15\\a2=3\\b2=18\\a3=7\\b3=21\\a4=8

we know that

\frac{b1}{a1}=\frac{15}{5}\\ \\b1=3*a1

\frac{b2}{a2}=\frac{18}{6}\\ \\b2=3*a2

\frac{b3}{a3}=\frac{21}{7}\\ \\b3=3*a3

a4=8

so

the next term should be

b4=3*a4=3*8=24

therefore

<u>the answer is</u>

24
