Answer 2

Answer:

area = 100 inches^2

Step-by-step explanation:

width = x

length = 4x

x + x + 4x + 4x = 50

10x = 50

x = 5

width = 5

length = 4 × 5 = 20

area = length x width

= 20 x 5 = 100

The second term of an arithmetic sequence is –39. The rule a, - a-1 +12 can be used to find the next term of the
sequence. What is the explicit rule for the arithmetic sequence?

Answers

Answer:

a 2 = -39

a 2 = a 1 + 12

- 39 = a 1 + 12

a 1 = - 39 - 12

a 1 = - 51 ( first term )

The common difference is : d = 12

The explicit rule for the arithmetic sequence:

a n = a1 + ( n - 1 ) d

a n = -51 + ( n - 1 ) · 12

The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.

Answers

Answer:

Step-by-step explanation:

The total shaded area = area of the square - area of a circle

= 9^2 - π * 4.5^2

= 17.3827

The 2 shaded parts both have area 8.69 unit^2 ( to nearest hundred)

Perimeter:

The perimeter of the top shaded part

= AB + 1/2 circmference of the circle

= 9 + 1/2 * 2 π r

= 9 + 14.137

= 23.14 units ( to nearest hundredth)

The bottom part has the same perimeter.

Answer:

area: 17.38 cm²perimeter: 46.27 cm

Step-by-step explanation:

You want the perimeter and area of the part of a 9 cm square remaining after a semicircle is removed from two opposite sides.

Area

The shaded area is the area of the 9 cm square less the area of a 9 cm circle. That area is ...

  A = s² -  π(s/2)² = s²(1 -π/4) . . . . . where s is the side length of the square

  A = (9 cm)²(1 -π/4) ≈ 17.38 cm²

The area is about 17.38 cm².

Perimeter

The perimeter is the circumference of the circle plus two sides of the square.

  P = C +2s

  P = πs +2s = s(π+2)

  P = (9 cm)(π+2) ≈ 46.27 cm

The perimeter is about 46.27 cm.

It is estimated the value of a new car decreases by 30% after one year of ownership. Find the
value of a car after one year of ownership if the cost of the new car was $24,300.

Answers

Answer: 17 010

If $24300 is the 100% (full price), then after year it would be 70% of that cost (because 100% decreases by 30% in a year). We can cross multiply the values:
$24300 100%
x 70%
so cross multiplying: 100 with x and 24300 with 70
-> 100x = 1701000
so the x will be 17010

Step-by-step explanation:

Pythagorean theorem: a^2 + b^2 = c^2

Now lets solve!!

12^2 + b^2 = 18^2

144 + b^2 = 324

Now we subtract!!

324 - 144 = b^2

180 = b^2

Now we need to find the square root!!

Max went to a shopping mall with $35 in his wallet. He spent two fifths of the money he had in his wallet at the bookstore. How much money, in dollars, did he have left?

$21
$26
$10
$13

Answers

Answer:

$21

Step-by-step explanation:

1) Find the amount spent.

"Two fifths" = 2/5

So, he spent 2/5 of 35.

= 2 x 35 / 5

= 70 / 5

= 14

2) Subtract 14 from 35, since 35 is the total amount of money he had.

= 35 - 14

= 21

Answer:

$21

Step-by-step explanation:

Given that:

Max went to a shopping mall with $35 in his wallet.

He spent two fifths of the money he had in his wallet at the bookstore.

To Find:

How much money, in dollars, did he have left?

Solution:

Let the left money that max have = x

Base on the given:

$35-(2/5)×$35=x

⇒ $35-($2×7)=x

⇒ $35-$14=x

⇒ x=$21

Hence, max has $21 left.

The total area of a pyramid is the sum of the areas of the triangular faces and the area of the base.

__

face area

Here, each triangular face has a base of 5 in, and a slant height of 7 in. Its area will be given by the area formula for a triangle:

  A = 1/2bh

  A = 1/2(5 in)(7 in) = 35/2 in² . . . . area of one of four congruent faces

__

base area

The area of the base is that of a square with 5-inch sides. It is given by the formula ...

  A = s²

  A = (5 in)² = 25 in²

__

total area

Then the total surface area is .

  area of base + 4 × triangle area

  = 25 in² + 4(35/2 in²) = 95 in² . . . . . surface area of the pyramid
